Title: Viscous fluid employed rotational type multiplate damper with adjustable brake force
Inventor: SUGASAHARA MORIHARU
IPC: F16F9/12
Filed: 1987-06-10
Abstract: PURPOSE:To enable an automobile to start smoothly by making variable a plate of free total length, which is the permissible range of fluctuation between a movable plate and a stationary plate, by the actuation of an adjusting member that can be operated freely from outside and also by adding to the plate of free total length an elastic origin body that shows restoring force against the reduction of the free total length. CONSTITUTION:As the length of a plate of free total length is shortened, it makes an elastic origin body 9 to accumulate elastic force in itself because the elastic origin body 9 is provided inside a casing 1. By doing so, when the plate of free total length is lengthened after reducing its elasticity once, not only does the plate surface space between the movable plate 6 and the stationary plate 7 follow the lengthened movement to return to the larger state but the space between the plates will never become close to zero by the elastic origin body 9 even if the plates are under an unusable state where the torque, which is the external force, can not be applied. The consequence is that the elastic fluid can be stored between the surface of the plates even if it is normal and the function of the plates as a damper against the external force becomes smooth.

Filed: 1980-10-15
Abstract: PURPOSE:To reduce a rising period loss during switching by a method wherein a switching circuit which is made conductive only during a rising period of a driving voltage input is provided in parallel with base input circuits of transistors arranged in a push-pull connection. CONSTITUTION:Switching circuits 14, 15 are connected in parallel with base circuits of tansistors 5, 6, and if switching circuits 14, 15 are closed, transistors 5, 6 are cut off, so collector currents do not flow. In this period a switching duration of the switching circuit 14 is adjusted in coincidence with a rising period between T1-T2 which is governed by a leakage inductance and a distributed parasistic capacitance of a transformer 7. Consequently by base currents of transistors being made null during this period T1-T2, collector currents are made null, and a switching loss of the period can be made null.

IPC: H01L27/10
Filed: 1993-06-17
Abstract: PURPOSE:To operate a circuits and to hold data in a relatively short time without a battery or a power source connected from an outside at the time of using the circuit. CONSTITUTION:A memory circuit part M and a power source circuit part A are provided on the same substrate. In the power source circuit part A, a capacitor C constituted of a high dielectric is serially connected with a resistance R. First, a voltage is impressed from an outside power source to a power source terminal V, and charged in the capacitor C. Next, when the outside power source is disconnected, a charged charge Q is discharged through the resistance R, and current is supplied to the memory circuit M. The insulating film of the capacitor C is SrTiO3 whose area is 1cm<2>, thickness is 10A, and dielectric film constant is 200. For example, the current consumption of a memory circuit with 4000 gates is almost 0.3mumA, and when the voltage impressed from the outside power source is 10V, 6000 second = 100 minute memory holding can be attained. Thus, information can be transferred while secrecy can be held in an IC memory or an IC card, and information can be prevented from leaking by automatically deleting data after the lapse of a holding time.

Title: Device and method for in-circuit test
Inventor: RONARUDO JIEI PAIFUA
IPC: G01R31/26
Filed: 1988-06-13
Abstract: PURPOSE:To prevent a transistor (TR) from being saturated and to test the base of the TR by generating a constant emitter current and determining a collector voltage and a base voltage substantially equally. CONSTITUTION:An operational amplifier 38 holds the voltage on a base lead 34 at a substantially zero potential, so a base-emitter voltage drop is about 0.7V and the emitter voltage Ve is therefore about -0.7V. Further, a collector lead 26 is coupled with an earth potential, so a collector-emitter voltage drop is -0.7V and the lead 26 has no resistance, so the voltage drop is held substantially constant. The collector-emitter voltage drop is large enough to prevent the TR 24 from being saturated and equals to the base-emitter voltage drop as long as a bias is applied to the TR 24. Further, a voltage level is held low, so another component connected to the TR 24 on a printed circuit board is prevented from being actuated.
