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: A shock absorber includes a bypass passage that is open from the side of a piston rod and causes an extension side chamber and a compression side chamber, which are divided by a piston in a cylinder, to communicate with each other; a shutter that is mounted on an outer circumference of the piston rod to be movable in an axial direction and opens or closes the bypass passage; and a coil spring that connects a rod guide mounted on one end portion of the cylinder and the shutter.

Abstract: A suspension device intervenes between a vehicle body and a wheel in a vehicle. The suspension device includes an outer tube coupled to the vehicle body, an inner tube inserted into the outer tube so as to allow the inner tube to advance and retreat, and a wheel-side bracket that includes a tubular holding portion into which an end portion on the wheel side of the inner tube is inserted and couples the inner tube to the wheel. The holding portion includes an annular ring disposed on the outer tube side and having an inner peripheral surface standing along an outer peripheral surface of the inner tube. The ring includes an outer peripheral tapered surface formed on an outer peripheral surface of the ring continuously from the end portion on the outer tube side of the inner peripheral surface and having a diameter gradually expanded to the holding portion side.

Abstract: A front fork includes a fork body having an outer tube and an inner tube relatively movably inserted into the outer tube in an axial direction, a damper housed in the fork body to dampen relative movement between the outer and inner tubes, a biasing member that biases the fork body in an expansion direction at all times, an annular dust seal that is held in the outer tube and makes sliding contact with an outer circumference of the inner tube, an annular oil seal that is held in the outer tube inside the fork body to be inner than the dust seal and makes sliding contact with the outer circumference of the inner tube, and a C-shaped scraper that is provided between the dust seal and the oil seal and makes sliding contact with the outer circumference of the inner tube.

Abstract: A wiper seal is less in sliding resistance that is encountered when the seal slides over a raceway surface of a guide rail, better in wear-proof quality, rich in durability, and further easy to steadily install it to a slider. The wiper seal is installed on one end of the slider in a linear motion guide system to wipe away foreign materials adhered on the guide rail. The wiper seal is made of polyester polyurethane foam having a reticular skeleton texture of three-dimensional construction including open-cells therein, the polyester polyurethane foam being squeezed or compressed into from ¼ to 1/20 in thickness to form a compact blank of three-dimensional construction having porosity therein. The wiper seal is set to come into sliding contact with the guide rail 1 to exert a positive interference of from 0.1 mm to 0.05 mm.

Abstract: By reducing the component count, a more compact linear motion guide unit having sealing structures capable of maintaining high sealing performance between slider and guide rail over a long term is realized. A rubber-made end seal, attached to each end face of a slider slidably straddling a guide rail, has a lip portion integrally formed on a contact face with the guide rail, and a recessed portion formed in a face opposite to a mounting face attached to the slider. A positional relationship is determined such that the lip portion is located closer to the slider than the recess bottom face is. An oil-impregnated wiper seal is mounted in the recessed portion of the end seal. A scraper is disposed along the outer side of the wiper seal mounted in the recessed portion, so that the wiper seal is fixedly interposed between the scraper and the recess bottom face.

Abstract: A linear motion guide system is disclosed in which a clearance between a slider and a guide rail is closed truly to clear foreign matter away from entering inside the system through any end of the slider traveling on the guide rail. Thus, the linear motion guide system is befitting to severe working environment where much foreign matter occurs. A highly-tight sealing unit is provided which is comprised of a cassette constituted with a front panel and an enclosure, a sealing plate stowed into the cassette, and a rear panel to close an open edge of the enclosure. The sealing plate is composed of an intermediate spongy medium flanked by skin layers, and lubricant is forcibly absorbed in pores or cells in the intermediate layer.

Abstract: A linear motion guide unit is provided in which a crowning portion available extensively for standard specification is made easily. The crowning portion is comparatively small in depth, and rich in high accuracy and high durability. A raceway groove for a load race in a carriage is made at an ingress/egress area thereof with the crowning portion of a curved profile that varies gently to allow the rolling element to move in and out of the load race with smoothness. The carriage is provided at the forward and aft ends of the raceway groove with rounded bevels, which are made in a curved contour merging into the associated crowning portion without causing any discontinuity at a junction of the rounded bevel with the crowning portion.

Abstract: Spring characteristics are switched in response to running conditions or use requirements of a bicycle in order to improve riding comfort and vehicle performance. A rod 2 is connected to a piston 3 which slides in a cylinder 1, a piston-side chamber (A) and a rod-side chamber (B) are partitioned in the cylinder 1 by the piston 3 and compressed air fills the two chambers, a passage 4 which connects the two chambers is opened and closed by a switch valve 5, the cylinder 1 is connected to the vehicle wheels and the piston rod 2 is connected to the vehicle body, the piston 3 displaces in response to vibration applied to the vehicle body in order to absorb vibrations.
