Title: Catalyst plug for nickel cadmium battery
Inventor: FUJITA YUUKOU
IPC: H01M10/52
Filed: 1983-08-05
Abstract: PURPOSE:To suppress temperature increase in charging by covering an alumina carrier with palladium and applying poisoning treatment with antimony and others to form a catalyst plug of nickel cadmium battery. CONSTITUTION:A catalyst plug which recombines hydrogen and oxygen evolved in charging of a nickel cadmium battery to form water is formed in such a way that alumina is used as a carrier and palladium is carried on the alumina carrier and poisoning treatment is applied with metal compound having poisoning action to palladium such as antimony, arsenic, or lead. In a nickel cadmium battery which is difficult to control increase rate of catalyst temperature and circulation efficiency, temperature increase in charging is effectively suppressed to increase recombining reaction of hydrogen and oxygen without sacrifice of circulation efficiency.

Then, an N<+> high concentration impurity is formed from the other primary face of the semiconductor substrate 1. The junction is 10mum or so in depth. Next, metal electrodes 5 and 6 are formed through evaporation. By these processes, a diode, which is very similar to a conventional one and whose electrode polarity is opposite to that of it, can be obtained and has an advantage in application.

Title: Control method of automatic clutch
Inventor: KAKINAMI TOSHIAKI
IPC: F16D48/02
Filed: 1985-06-29
Abstract: PURPOSE:To control the gearing rate of a clutch adequately with no complicated driving system, by setting a clutch stroke responding to the engine revolutions and the accelerator pedal stepping rate, and securing the clutch stroke by the force of the driving system. CONSTITUTION:A piston 31 of an actuator 3 acts as a driving force to the left by the force of the clutch spring of a clutch 2. A clutch stroke responding to the engine revolutions is set, and if the present stroke is different from the set stroke, electromagnetic valves V1 and V2 are accelerated or decelerated by the signals from a microcomputer, to increase or reduce the control oil in the actuator 3, to convert the present value at an amount of the set driving amount. Thus, the clutch stroke is driven and controlled securely. Therefore, even if the clutch spring has an unlinear feature, it imposes no influence. Moreover, by setting the driving rate depending on the clutch stepping rate, the control response at the starting can be made smooth.

IPC: G02B6/44
Filed: 1992-05-11
Abstract: PURPOSE:To prevent the increase of loss at the time of a cable being bent by forming the bottom face of the groove of a storage member into the curved recessed face smoothly continuous from the side face, and setting the width of the groove to such width that the laminated body of tape like optical fibers is rotatable inside.

The laminated body of the tape like optical fibers 28 can be thereby rotated easily in the groove 12. Accordingly, in the case of a cable being curved, the tape like optical fibers 28 are rotated in the direction of minimizing mechanical energy accumulated therein, so that the compressive distortion of the side edge part is reduced to prevent the generation of micro-bending. This results in preventing loss increase caused by the micro-bending of the optical fibers.
