Title: Malfunction preventing circuit
Inventor: SUZUKI YASUAKI
IPC: H03K5/1252
Filed: 1988-05-23
Abstract: PURPOSE:To eliminate noise without causing the reduction in fan-out, reduction in the mount density and any cost-up by providing a delay circuit outputting plural delay signals and a logic circuit taking majority decision logic of plural delay signals and giving an output. CONSTITUTION:A delay circuit 10 gives delays of '0',  t and  t2 to a digital input signal to generate three delay signals. A logic circuit 12 takes majority decision logic of the three signals. For example, suppose that noise is superimposed on, e.g., a digital signal and the signal level is changed momentarily to a high level, then the high level is given to the logic circuit 12 as it is and delayed by  t and t2 the result is given to the logic circuit 12. As a result, when one of inputs to the logic circuit 12 is at a high level, the other two inputs are at a low level without fail. Thus, the majority decision logic results in a low level. The noise is eliminated from the input signal as the output of the logic circuit 12.

Title: Manufacture of shaft of magnetostrictive torque sensor
Inventor: SHIBATA YOSHIO
IPC: G01L3/10
Filed: 1989-05-18
Abstract: PURPOSE:To improve the mechanical strength, specially, fatigue strength by generating compressive stress which is larger than compressive yielding stress in a shape cut part with compressive remaining stress and torsion torque, then removing the torsion torque and providing magnetic anisotropy. CONSTITUTION:A couple of shape cut parts 2 and 3 which slant in axially opposite directions are formed in the shaft body 1 and the compressive remaining stress is applied to the shaft body 1. Then the torsion torque is applied to generate compressive stress which is a stress convergence coefficient larger than in other parts in the shape cut parts 2 and 3. At such a time, even when the torsion torque is applied so that the total of the compressive stress and compressive remaining stress of the shape cut parts 2 and 3 is larger than the compressive yielding stress of a shaft material, stress which is larger than the compressive yielding stress does not operate on the shaft body 1 and the total of both the compressive stress and compressive remaining stress is less than the compressive yielding stress except in the shape cut parts 2 and 3, so when the torsion torque is removed, and compressive remaining stress is released in the shape cut parts 2 and 3 and the compressive remaining stress in other parts decreases, thereby giving the magnetic anisotropy based upon the remaining stress.

Abstract: PURPOSE:To enable the supply of large amount of lubricant by finishing the final end of a spiral groove provided at a rotary shaft before the free end of a bearing part, and widening the inner dia. of bearing from the free end to the final end. CONSTITUTION:Lubricant 10 at the bottom of an enclosed vessel 1 is pressure- fed to the inner dia. face of intermediate partition plate 16 with a pressure difference. The lubricant 10 thereat passes through a space between a piston 5 and an eccentric part 4 through a spiral groove 13 provided at an eccentric part 4 of a rotary shaft 3 to perform the lubrication thereat. The lubricant enters thereafter to a bearing part of side plate 22 to lubricate it while flowing through the groove 13. In this case, the final end of groove 13 of bearing is located inside the opening end 15, thereby gas does not flowed back from a high pressure closed vessel 1 side, while the inner dia. near the end 15 is enlarged, thereby there is no interference to the flow of lubricant 10. It is thus possible to flow the lubricant in large amount perform operation at high speed and high load.
