Abstract

A method for polishing a diamond crystal includes preparing a diamond crystal having a main surface having a plane orientation of (100). Mechanical polishing is performed on the main surface using a polishing wheel such that: a tangent contacts a curve extending in a rotation direction of the wheel and contacting a contact position between the diamond crystal and the wheel that is rotating; and a tangent direction of the tangent at the contact position is within a range of ±10 degrees relative to a <110> direction of the diamond crystal, thereby causing an affected region to appear such that the affected region is parallel to a direction of a plane orientation (111) of the diamond crystal and penetrates the diamond crystal onto the main surface. Chemical mechanical polishing is performed on the main surface to remove the affected region, thereby removing the affected region from the main surface.

Abstract

Provided is a method for manufacturing a self-forming optical waveguide, the method comprising producing a structure in which a photo-curable resin is disposed between a diffraction grating coupler provided in a silicon waveguide and an optical fiber disposed in the diffraction direction of light to be emitted from the diffraction grating coupler, wherein the optical fiber has a cladding and at least one core, and the photo-curable resin includes a core part forming resin that is polymerized and cured by incidence of light in a predetermined wavelength band thereon and has a refractive index na, and a cladding part forming resin that is polymerized and cured by incidence of light with an intensity higher than or equal to that of the light incident on the core part forming resin thereon and has a refractive index nb after cured, the nb being higher than the na. The method further comprises forming an optical waveguide in the photo-curable resin by forming a core part of the optical waveguide in the photo-curable resin by causing the polymerization and curing of the core part forming resin by bidirectional light irradiation for causing light with an intensity at which only the core part forming resin can be polymerized to be incident on the photo-curable resin from each of the optical fiber side and the silicon waveguide side, and by forming a cladding part of the optical waveguide, wherein the bidirectional light irradiation causes light to be incident on the photo-curable resin from the core of the optical fiber, and causes light having propagated through the silicon waveguide to be incident on the photo-curable resin via the diffraction grating coupler.

Abstract

The present invention provides a method for producing a self-forming optical waveguide, the method involving preparation of a photocurable resin and two multicore fibers which each comprise a plurality of cores, wherein the photocurable resin contains a core part-forming resin which is polymerized and cured when light in a specific wavelength band is incident thereon and has a refractive index na, and a cladding part-forming resin which is polymerized and cured when light that has an intensity not less than the intensity of the light incident on the core part-forming resin is incident thereon and has a refractive index nb after curing, the refractive index nb satisfying nb < na. The method also involves: arranging the two multicore fibers so as to face each other, and disposing the photocurable resin between the multicore fibers; having light that has an intensity with which only the core part-forming resin can be polymerized incident on the photocurable resin from the cores of the two multicore fibers so as to cause the polymerization and curing of the core part-forming resin, thereby forming core parts of optical waveguides within the photocurable resin; and subsequently forming cladding parts, thereby self-forming a plurality of optical waveguides within the photocurable resin.

Abstract

The present invention provides a method for producing a self-forming optical waveguide. A photocurable resin and two multicore fibers, each of which has n cores (n is a natural number of 2 or more), are prepared. The photocurable resin contains: a core part forming resin which is polymerized and cured when light within a specific wavelength range is incident thereon, and which has a refractive index na; and a cladding part forming resin which is polymerized and cured when light that has a higher intensity than the light that is incident on the core part forming resin is incident thereon, and which has a refractive index nb after curing, the refractive index nb satisfying nb < na. The two multicore fibers are arranged so as to face each other; and the photocurable resin is arranged between the multicore fibers. Light from the cores of the two multicore fibers is caused to be incident on the photocurable resin, thereby forming a core part. Subsequently, light is caused to be incident on the core part so that light leakage to the cladding part forming resin occurs, thereby polymerizing and curing the cladding part forming resin around the core part so as to form a cladding part.

Abstract

[Problem] To provide a luminous body capable of changing color in response to emission (ON) or non-emission (OFF) of ultraviolet light, in particular, a watch component provided with the luminous body, and a watch provided with the watch component. [Solution] This luminous body is provided with a phosphorescent material and a fluorescent material. The phosphorescent material and the fluorescent material both emit light when light having a wavelength of 315 nm or more and less than 380 nm is shone onto the luminous body. Thereupon, the light emitted from the phosphorescent material and the fluorescent material mixes and is emitted from the luminous body. Next, when the state in which the light being emitted from the phosphorescent material and the fluorescent material is mixing and is being emitted from the luminous body transitions to a state in which the light having a wavelength of 315 nm or more and less than 380 nm is not being shone, only the phosphorescent material emits light. In addition, the watch component is provided with the luminous body, and the watch is provided with the watch component.

Abstract

A power generation mechanism includes a first movable member, a second movable member, a twisted coil spring, a power generator, and a housing. The first and second movable members are gears. First and second wound parts of the spring are wound around a first center shaft in opposite directions. Initial elastic energies ie1 and ie2 are respectively applied to the first and second wound parts, absolute values of ie2 and ie1 being equal. The second movable member is turnable by a force from outside the mechanism, engaging teeth of the first and second movable members together to turn the first movable member. With ie12 accumulating on the first wound part and with the teeth disengaged from each other, the first center shaft is turned in an opposite direction by ie12 to generate power in the power generator. Also, the first center shaft is turned by ie1 and ie2.

Abstract

A pigtail-type optical receptacle includes a ferrule, an optical fiber, a protective member, a sleeve, and a holder. The ferrule has a through-hole extending in an axial direction. The optical fiber is held by the ferrule in a state of being inserted into the through-hole and extends outside the ferrule from a rear end side of the ferrule. The protective member covers a portion of the optical fiber extending outside the ferrule. The sleeve engages an outer surface of the ferrule. The through-hole includes a first region and a second region. The second region is disposed rearward of the first region. The width in an orthogonal direction orthogonal to the axial direction of the through-hole in the second region widens toward the rear end side of the ferrule. The holder holds a portion of the outer surface of the ferrule rearward of the first region.

Abstract

A clutch device includes an input disc, an output disc, and a biasing member configured to press the input disc against the output disc. A rotation load applied to an output shaft separates the input disc from the output disc against biasing force of the biasing member. The input disc and the output disc include opposing surfaces, each of which includes axially disengageable overlapping tooth portions. Recessed and raised portions of each tooth portion are formed continuously in a radial direction and are alternately arranged in a circumferential direction. Each of the curved shapes of the recessed and raised portions is maintained at a respective identical height while a circumferential width thereof continuously expands in a radially outward direction. Also disclosed is a motor unit including the clutch device. The disclosed clutch device reduces, e.g., deformation or damage of a disengageable portion, and therefore, can improve durability.
