LLL of the hole of the support member, and the outer circumferential surface of the tubular fabric is disposed on the inner circumferential surface of the hole of the support member so as to cover the contact portion between the inner circumferential surface of the support member and the member to be sealed.
In the present invention, in order to provide a shaft-sealing unit of superior sealing performance, low friction, enhanced lifetime, and simple structure, a shaft-sealing unit for a rotator shaft part, which is for restrictively controlling the shifting of powder between an outer peripheral component and a cylindrical rotational-shaft-driven member that follows the rotation of a rotational shaft, is configured so as to comprise an outer peripheral component provided with a cylindrical cavity of circular cross-section, and a cylindrical rotational-shaft-driven member arranged in the cylindrical cavity, wherein: the outer peripheral component, along the inner circumferential surface of the cylindrical cavity thereof, is provided with a sealing member; the inner-circumferential face section of the sealing member abuts on the outer circumferential surface of the cylindrical rotational-shaft-driven member; the cylindrical rotational-shaft-driven member is made of a plastic resin polymer and is provided with a rotational-shaft insertion hole in the center thereof; and the inner diameter of the cylindrical rotational-shaft-driven member is less than the outer diameter of the rotational shaft.
In order to provide a covered roller that improves productivity, reduces cost, and sufficiently achieves anchoring of a covering, and to provide a means for detecting the lifespan of said covered roller, a roller is used wherein a rotating body that is covered with a covering has a region where an insertion member is inserted into the inside of the rotating body with the covering interposed therebetween. An end section of the covering in a region that protrudes from the rotating body is formed to have an inner circumference that is the same as or smaller than the inner circumference at the inner diameter of the rotating body, either by configuring the covering to be longer in a width (axial) direction than the width of the rotating body that is covered with the covering, allowing the covering to protrude from the rotating body, and using heat to subject the covering to thermal contraction in the radial direction, or by configuring the covering to be expandable/contractable in at least the radial direction and to be longer than the width of the rotating body that is to be covered with the covering, applying the covering to the rotating body, allowing the covering to protrude from the rotating body, and allowing the covering to contract. The covering in the protruding section is folded back toward the inside of the rotating body, the insertion member is inserted according to at least a press-fitting condition into the inside of the rotating body with the covering interposed therebetween to hold the covering on the surface of the rotating body, and at least the rotating body, the covering, and the insertion member are unified.
This liquid sprayer comprises: a nozzle section for spraying a liquid; a pump, namely a piston pump with a piston that moves in a reciprocating manner, said pump comprising a suction section for suctioning the liquid, and a discharge section that is connected to the nozzle section and discharges liquid suctioned from the suction section; and a drive means that includes a cam section and a moving member having formed therein a cam hole into which the cam section is fitted, in which rotating movement of the cam section causes the moving member to move in one direction or the other direction along a linear path of movement perpendicular to the rotational axis of the cam section, movement of the moving member in the one direction causes the pump to suction the liquid, and movement of the moving member in the other direction causes the piston to move in the same direction, compress the suctioned liquid, and discharge the result from the nozzle section. The pump is configured so that the load within the pump fluctuates as a result of one instance of reciprocating movement of the piston, and the drive means includes a motor for applying rotary force around the rotational axis of the cam section and is configured so that the load fluctuation of the load torque of a rotating shaft is synchronized with the load fluctuation within the pump.

CLEANING MEMBER FOR CLEANING SMOOTH SURFACE COMPRISING WOVEN FABRIC WITH STRIPED PATTERN AND SUPPORT MEMBER FOR WOVEN FABRIC
In order to provide a cleaning member having a fibrous material, with the surface of the cleaning member formed of plain weave or twill weave fibrous material and satin weave fibrous material, with which attachment of particles to the surface or inside of the fibers is prevented and the effect of scraping particles is maintained for a long time, a cleaning member 1 for cleaning particles 6 and liquid contained in dust, powder, or liquid which are attached onto an approximately smooth surface is characterized by comprising a woven fabric 2 with a striped pattern and a support member 5 for the woven fabric, the woven fabric 2 having a surface which is the face brought into contact with particles 6 or liquid and is formed from a recessed stripe part 3 and a projecting stripe part 4, wherein particles 6 and liquid contained in dust, powder, or liquid attached onto an approximately smooth surface are cleaned by steps 13 formed by the recessed stripe part 3 and projecting stripe part 4 of the woven fabric 2 with a striped pattern, the relative speed of the cleaning member 1 having the woven fabric 2 with a striped pattern formed from the recessed stripe part 3 and projecting stripe part 4, the abutting load of the cleaning member 1, and the action of scraping particles 6 by, for example, the angle of the projecting stripe part 4 of the woven fabric 2 with a striped pattern formed from the recessed stripe part 3 and projecting stripe part 4.
A droplet jetting apparatus includes: a nozzle that ejects a jet of liquid droplets; a detector that detects a hand or an object in a flight path of liquid droplets from the nozzle; a pump including a suction portion for suction of liquid, and a discharge portion which is connected to the nozzle and discharges the liquid which has been sucked into the suction portion; a driver which by rotation of a cam, sucks liquid into the pump and discharges the liquid in a compressed state; and controller which actuates the driver. When the detector detects the hand or object, the controller actuates the pump by rotation of the cam, and ejects a jet of liquid in droplet form from the nozzle.
