Abstract: A three-dimensional display including a laminate sheet with first element cells with recorded personal identification information, and second element cells carrying an authentication medium with visible personal identification information, including a first region and a second region formed by arranging first element cells and second element cells which form respective phase shift structures; the first element cells and the second element cells arranged in an interleaved manner at a predetermined ratio to form respective three-dimensional structures; the first region and the second region are visible respectively from first and second sides of the laminate sheet; a first reconstructed image is produced on the first side of the laminate sheet due to the phase shift structure formed by the first element cells; and a second reconstructed image is produced on the second side of the laminate sheet due to the phase shift structure formed by the second element cells.

Abstract: The present invention has an object to provide an on-vehicle air conditioner that can prevent breakage or the like caused by applying a high voltage. In an inverter system 20 that controls an operation of a motor 30 of a compressor for the on-vehicle air conditioner, a motor control microcomputer 24 operates by converting a voltage supplied from an on-vehicle battery power source 50 into a low voltage. Thus, the motor control microcomputer 24 is operated to perform failure diagnosis of a high voltage circuit Cb without a high voltage power source 40 being turned on. The failure diagnosis can be performed without power being supplied from the high voltage power source 40 to the high voltage circuit Cb, thereby preventing the high voltage circuit Cb from being broken by applying the high voltage even when there is some failure in the high voltage circuit Cb.

Abstract: Screw thread holes 20 circumferentially spaced from each other are formed in a first ring 10, and through holes 21 circumferentially spaced from each other are formed in a second ring 11. A screw thread section 40 and a press fitting section 42 are formed on the outer periphery of each pin 13. The minimum inner diameter of the through holes 21 in the second ring 11 is set greater than the maximum outer diameter of a portion of the pin 13 which is positioned closer to the screw thread section 40 than the press fitting section 42. The screw thread sections 40 of the pins 13 are screwed into the screw thread holes 20 in the first ring 10, and the press fitting sections 42 of the pins 13 are fixed in the through holes 21 in the second ring 11 by interference fit.

Abstract: To provide a method of producing an outer ring of a self-aligning bearing in which at a raceway-turning step after a heat treatment, the chipping of a turning tool and damage of a raceway can be prevented. Before the heat treatment, an annular groove 2b is formed in that portion of the raceway 2a of the outer ring 2 corresponding to lubrication holes 7, thereby avoiding a situation in which a discontinuous cutting operation occurs because of the lubrication holes 7 at the raceway-turning step after the heat treatment.

Abstract: A double-row spherical roller bearing comprises an inner race, an outer race, two retainers each molded of a synthetic resin, and double-rows of spherical rollers rotatably received in pockets of the retainers and arranged one after another in the equally spaced relationship in the circumferential direction. Each retainer is molded such that an annular portion on the large diameter side and an annular portion on the small diameter side are integrally jointed to each other with a plurality of retainer bars bridges therebetween. Each retainer bar comprises an inner portion located on the inner race side and an outer portion on the outer race side. Each side surface of the inner portion is defined by a part of the spherical surface extending around the spherical surface of each spherical roller. In addition, each side surface of the outer portion is defined by a first surface, a second surface and a third surface.

Abstract: A rolling body retaining member comprising, based on the whole weight thereof, 15 to 50 wt. % of glass fiber or like reinforcing fiber, 5 to 15 wt. % of carbon powder, and the balance polyether ether ketone resin.

Abstract: A composite cylindrical roller bearing assembly including an inner ring having an annular projection on its outer peripheral side, an outer ring having an annular recess to receive the annular projection on its inner peripheral side, upper and lower cylindrical thrust rollers held by upper and lower retainers and disposed in upper and lower spaces formed above and below the projection in the recess, cylindrical radial rollers held by a retainer and disposed in an annular space between peripheral surfaces of the recess and the projection, and an annular gear to be meshed with an external gear. The inner ring is divisibly composed of first, second and third annular inner ring sections each of which is divisibly composed of two generally semicircular parts. One of the above annular inner ring sections has projections defining teeth of the annular gear on its inner peripheral side.
