IPC: H03K17/725
Filed: 1986-06-26
Abstract: PURPOSE:To obtain an alarm contact operating accurately in response to temperature rise by containing a shape memory alloy bonded to the heat sink member of a reverse blocking 3-terminal thyristor and the alarm contact activated by the restoring force of the shape memory alloy to the original shape into a case. CONSTITUTION:The shape memory alloy 3 bonded to the heat sink member of the reverse blocking 3-terminal thyristor 1a and the alarm contact 11 operated by the restoring force of the shape memory alloy into the original shape are contained into the case 6. The shape memory alloy deformed plastically is fitted to a copper base 3 as the heat sink member closest to the reverse blocking 3-terminal thyristor and when the copper base reaches a prescribed high temperature, since the shape memory alloy is restored into the original shape at an accurate temperature, the restoring force at the shape change is utilized to activate the alarm contact. The alarm contact is connected to block the trigger of the reverse blocking 3-terminal thyristor to a control circuit 10.

Abstract: PURPOSE:To obtain an electric anisotrophy by using TiO2 of a needleshaped grain form when PbTiO3-PbZnO2 piezoelectric material or a tricomponent piezoelectric material added with a composite brobuskite compound as the third component is manufactured. CONSTITUTION:Highly acidic TiCl3 is kept at approximately 30 degrees C and then is subjected to thermal treatment for approximately 40hr in the atmosphere.  Produced white sediment is sufficiently water-washed, and then is filtered/ dried  into needle-shaped TiO2. Next, this TiO2 is scaled together with Pb(COOH)2 of  0.2mum grain size on the average and ZrO2 of 0.1mum grain size on the average so that the composition may be Pb(TiO70ZrO30)O3. Following this procedure, it is sufficiently mixed by means of a ball mill. Later this mixture is thermally treated for approximately 2hr at 700 deg.C and is crushed into piezoelectric body material. Thus, it  is possible to orient in a fixed direction or a fixed plane direction the crystal bearing  of a crystal grain which could not be obtained before.

Title: Rush current prevention circuit
Inventor: KIMURA YASUHIRO
IPC: H02J1/00
Filed: 1995-06-19
Abstract: PURPOSE: To suppress a rush current at the time of the instantaneous interruption of electric supply. CONSTITUTION: A charge/discharge control circuit 25 turns off a switching element 24 at application of power to charge a capacitor 22 by a current from a current supply circuit 23 and turns off the switching element 24 at interruption of power to discharge the charge in the capacitor 22 momentarily. Thus, at application of power, the drain-source resistance of a FET 21 changes from infinite to an on-resistance thereby suppressing the rush current at application of power. On the other hand, the charge in the capacitor 22 is instantaneously discharged via the switching element 24 at interruption of power to instantaneously reset the FET 21. Since the FET 21 is instantaneously reset at interruption of power in this way, the rush current is immediately suppressed even when power is applied after the interruption of power.
