Abstract

A multi-joint-robot linear-member-shape simulator receives a position of at least one via point via which the linear member extends between a start-point position and an end-point position, an initial position of an adjustment via point that adjusts a length of the linear member, and an adjustment parameter of the adjustment via point, and repeatedly executes shape control for determining the shape of the linear member and a length adjustment for determining the length of the linear member when the linear member has the determined shape by using the input position of the via point and the input initial position of the adjustment via point as an initial value until a difference between an actual length of the linear member and the determined length thereof becomes smaller than or equal to a permissible value. When the shape control is to be executed, the adjustment parameter is changed.

Abstract

A building time for building an additively-manufactured object is calculated on the basis of the inter-pass time and the welding pass time and is compared with a preset upper limit value, and welding conditions in a depositing plan are repeatedly modified until the building time is equal to or less than the upper limit value. Alternatively, corrections are repeatedly performed until the shape difference between a building shape of built-up object shape data relating to the additively-manufactured object created on the basis of the inter-pass time and the inter-pass temperature, and a building shape of three-dimensional shape data, is smaller than a near net value.

Emitting light luminances of a surface of a steel sheet are measured at respective measurement wavelengths different from each other, and a temperature of the surface of the steel sheet is measured to thereby calculate the emissivity at each of the measurement wavelengths. Calculated in connection with the emissivity calculated at each of the measurement wavelength are the layer thickness corresponding to the emissivity at the measurement wavelength, and a ratio at the layer thickness by using the layer thickness conversion information corresponding to the measurement wavelength. The calculated thickness is extracted as a candidate value for an actual layer thickness when the calculated ratio is within the preset extent assigned for the layer thickness conversion information.

Abstract

A hydraulic drive apparatus includes a boom flow rate control valve, a target boom cylinder speed calculation part, a pressing force calculation part, a correction part, and a boom flow rate operation part. The target boom cylinder speed calculation part calculates a target boom cylinder speed for making the construction surface by the bucket closer to the target construction surface. The pressing force calculation part calculates the pressing force by which the bucket is pressed against the construction surface, based on the cylinder thrust of the boom cylinder and the center-of-gravity position information on the center-of-gravity position of the work device. The correction part corrects the target boom cylinder speed to make the deviation between the target pressing force and the calculated pressing force closer to 0. The boom flow rate operation part operates the boom flow rate control valve to provide the corrected target boom cylinder speed.

Abstract

A piston ring includes a first ring portion which is fitted onto an outer circumferential portion of a piston and which is capable of sliding relative to an inner wall surface of a cylinder, and a second ring portion which is fitted onto the outer circumferential portion of the piston, arranged side-by-side with the first ring portion in the axial direction, and which is capable of sliding relative to the inner wall surface of the cylinder. The second ring portion is fitted onto the outer circumferential portion of the piston in such a way as to be positioned on a side opposite to a compression chamber inside the cylinder, relative to the first ring portion, and has a greater hardness than the first ring portion has.

Abstract

Formed in series along an axial-direction end portion of a large-diameter pipe member, in the following order from the pipe end, are: a large-diameter-pipe pipe-end expanding portion; a large-diameter-pipe reduced-diameter portion; a large-diameter-pipe bulging portion; and a tapered portion. Formed in series along an axial-direction end portion of a small-diameter-pipe member, in the following order from the pipe end, are: a small-diameter-pipe pipe-end expanding portion; a small-diameter-pipe enlarged-diameter portion; and a small-diameter-pipe bulging portion. The outer cylindrical surface of the small-diameter-pipe enlarged-diameter portion is in close contact with the inner circumferential surface of the large-diameter-pipe reduced-diameter portion; the inner cylindrical surface of the large-diameter-pipe bulging portion and the outer circumferential surface of the small-diameter-pipe pipe-end expanding portion are engaged; and the inner circumferential surface of the large-diameter-pipe pipe-end expanding portion and the outer cylindrical surface of the small-diameter-pipe bulging portion are engaged.
