Abstract: An information processing apparatus (1) included in a welding training system includes a distance determination unit (13) configured to determine a distance between a tip of a welding rod object used for a welding operation and a parent material object based on a distance between the parent material object and a dot object used for distance determination, the dot object being located at the tip, a welding processing performing unit (14) configured to perform welding processing in virtual space when the determined distance is less than or equal to a predetermined threshold value, a welding rod length corrector (15) configured to perform, when the welding processing is performed, a correction such that an axial length of the welding rod object is shortened, a distance determination object mover (17) configured to move the dot object to the tip of the welding rod object after the correction, and a display controller (19) configured to cause a display to display an image including the welding rod object after the

Abstract: An information processing apparatus (1) included in a welding training system includes a transmittance adjuster (14) capable of adjusting a transmittance of a window of a welding helmet in virtual space in multiple grades, and a display controller (17) configured to cause a display of an HMD (2) to display a situation of a welding operation in the virtual space at an illuminance corresponding to the adjusted transmittance. The transmittance adjuster (14) adjusts the transmittance based on a skill level of a trainee determined by a skill level determination unit (13).

Abstract: The present invention provides a method for producing a durable semispherical shoe which can be prevented from being subjected to seizure even in a dry lubrication state in which there is no lubricating oil at a start time of an operation of a swash plate compressor, can be restrained from deteriorating in its lubricating property due to generated frictional heat, and can be restrained from deteriorating in its strength at a production time and an injection molding die. A semispherical shoe (4), for a swash plate compressor, to be produced by the production method has a base material (5), consisting of a hard material, which has a hollow part along a central axis thereof and a resin layer, consisting of a resin composition, which is formed on a surface of a planar part, disposed on a periphery of the base member, which is to be subjected to sliding contact with the swash plate and on a surface of a spherical part, disposed on the periphery thereof, which is to be subjected to sliding contact with a piston.

Abstract: A swash plate compressor in which a lubricating film is not formed on a sliding contact surface of the swash plate and the piston owing to the use of the semispherical shoe. The semispherical shoe (4) is subjected to sliding contact with the swash plate of the swash plate compressor and the piston thereof. A base material (5) consists of a metallic member having a resin layer (6b) formed on a surface of a planar part (4b) that is subjected to sliding contact with the swash plate. A resin layer (6a) is formed on a surface of a spherical part (4a) to be subjected to sliding contact with the piston. The resin layer (6a) and the resin layer (6b) are integral with each other. At least one portion of the base material (5) is exposed.

Abstract: A resin coating-provided swash plate, for a swash plate compressor, manufactured by a process shorter than a process of a conventional coating method and which allows the resin coating to be subjected to grinding processing with high accuracy and to have a high strength of adhesion to a base material of the swash plate, a method for manufacturing the swash plate, and the swash plate compressor having the swash plate. A swash plate (3) for a swash plate compressor is so constructed that inside a housing where a refrigerant is present, a rotational motion of the swash plate (3) mounted perpendicularly and obliquely on a rotational shaft by directly fixing the swash plate (3) thereto or indirectly fixing the swash plate thereto through a coupling member to the rotational shaft is converted into a reciprocating motion of a piston.
