  • Bush with a spherical sliding surface
    Patent number: 4714368
    Abstract: A bush with a sliding surface comprising a socket, a ball-integral shaft having shaft portions on both sides of a ball portion, a bearing body location between the socket and the ball-integral shaft, and a cushion having recesses in at least one axial end portions thereof constructed of polyurethane resins or polyester resins. Excellent absorption of manufacturing tolerances of parts of the bush and easy adjustment of rotational torque of the bush in normal operating conditions are obtained through use of the bush of the present invention. Additionally, the bush can show excellent load bearing characteristics even when the bush receives large loads beyond normal operating loads. Further, the durability of the bush is improved.

  • Electrostatic reproducing apparatus
    Patent number: 4505572
    Abstract: An electrostatic reproducing apparatus characterized in that a sensor unit consisting integrally of at least one light emitting element and one light receiving element is disposed close to the surface of a photosensitive member at a position downstream of the position where the printed sheet of recording paper separates from the photosensitive member. One of the light emitting elements is a visible-light emitting diode for detecting jamming of the sheet of recording paper and the other light emitting element is an infrared-light emitting diode for detecting the toner concentration.

  • Dense sintered silicon carbide ceramic
    Patent number: 4354991
    Abstract: A dense sintered silicon carbide ceramic has high strength and a flexural strength of at least 25 kg/mm.sup.2 at room temperature and 1400.degree. C. which is obtained by molding a mixture of an aluminum oxide source at a ratio of 0.5 to 35 wt. % as Al.sub.2 O.sub.3 and silicon carbide at a substantial residual portion followed by a pressureless sintering.
