Title: Spherical sliding bearing
Inventor: MIYAKE SHIYOUJIROU
IPC: F16C23/04
Filed: 1983-09-29
Abstract: PURPOSE:To improve reliability and precision by inserting, between sliding surfaces of an inner wheel and an outer wheel, an elastic plate which has radius of curvature different from that of the sliding surface.

Abstract: PURPOSE:To measure a D.C. current amplification factor without the operation of correction by applying a prescribed collector-emitter voltage to a transistor to be measured while a constant current flows to the base thereof with a voltage follower circuit. CONSTITUTION:As the amplification level of arithmetic amplifiers 7 and 9 ranges from 80dB to 120dB, current running to an inversion terminal of an arithmetic amplifier 7 forming a voltage follower and current flowing to a non-inversion terminal of an arithmetic amplifier 9 forming a constant current power source are so minimal that errors can be ignored in the measured values due to these currents. Current flowing through a variable resistor VR1 is so minimal as to ensure the prescribed value VCE by VR1 not affected by current IC. On the other hand, the base current IB can be set so easily by VR2 as to give a collector current IC in a stable condition thereby making it easy to attain hFE= IC/IB.
