Patent JP-S62238606-A (JP)
Title: Protection apparatus for superconducting energy storage system
Inventor: KAWAKAMI NORIKO
IPC: H02H7/00
Filed: 1986-04-09
Abstract: PURPOSE:To protect a system against an excessive voltage rising sharply, by providing a short-circuit switch which is automatically turned ON by an excessive voltage across a superconducting coil and also providing a permanent switch detecting the operation of the short-circuit switch to cause short-circuits across the coil. CONSTITUTION:When any disorder occurs in a GTO converter 7, a circuit constituted by a superconducting coil 8 of the GTO converter 7 is opened to cause direct current to flow into surge absorbtion capacitances 5A 5F of the GTO, providing an excessive voltage. An excessive voltage detection circuit 9 is thereby actuated and a short-circuit switch 10 is closed. A current transformer 11 detects the electric current flowing through the short-circuit switch 10, and an operation detector 12 detects a value of the electric current flowing through the current transformer 11. When electric current flows through the short-circuit switch 10, a heater switch 13 is opened and, therefore, no current flows through a heater 15. A permanent switch 16 switches over to the superconducting state and the electric current which has been flowing through the superconducting coil 8 is circulated to the permanent switch 16. Thus, electric current is allowed to flow permanently.

Title: Camera
Inventor: UCHIYAMA HIROYUKI
IPC: G03B15/03
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent a backup capacitor for autofocusing from being ruptured in the case of performing inspection by using a constant-voltage type stabilized power source device as the power source of the camera. SOLUTION: A stroboscopic circuit 41 and an AF circuit 43 are incorporated in a camera main body. At the time of inspection in a factory, the constant- voltage stabilized power source device 35 is used as the power source instead of a battery 31. In the device 35, a load current is largely fluctuated in the midst of charging a main capacitor 41a in the circuit 41, so that output voltage happens to exceed the breakdown strength of the backup capacitor 46d for applying an auxiliary current to an IRED 46a. A control circuit 40 makes a transistor for protection 50 in an off-state before charging a main capacitor 41a, and separates the transistor 50 from the power source in the midst of charging.
Patent JP-H03276524-A (JP)
Title: Contact device
Inventor: KITAMURA TSUNEHIRO
IPC: H01H1/50
Filed: 1990-03-27
Abstract: PURPOSE:To restrain a contact bounce due to the collision energy of contacts by applying suction force generated with a permanent magnet to a direction in which a movable contact is not apart from a fixed contact. CONSTITUTION:When contact pressure is assured with a movable spring 2 driven with a card 3 to press a movable contact 2a to a fixed contact 1a, suction force Pm generated with a permanent magnet 5 is applied to a movable plate 4, a magnetic body. At that time, a gap is to be left between the movable plate 4 and the permanent magnet 5 so as to ensure contact pressure with both the contacts. Consequently the suction force Pm is applied in a direction in which the movable contact 2a is not apart from the fixed contact 1a. This causes a contact bounce, due to collision energy of the contacts, difficult to occur.

Title: Appreciating device of microcomputer
Inventor: KAWADA KAZUHIDE
IPC: G06F9/455
Filed: 1981-05-27
Abstract: PURPOSE:To exactly appreciate an analog part without generating a noise at all, by using a microcomputer for a supervisor part, and inhibiting read of a program of this computer in case of measuring the characteristics of the analog part. CONSTITUTION:While an SOD terminal of a supervisor MPU10 is ''1'', ''0'' is inputted to an RUN terminal of an emulator 11, and the emulator 11 becomes an RUN state. In this case, since outputs of a bus driver 20 and a duplex bus driver 23 are inhibited, the emulator 11 and the MPU10 are not emulated. Subsequently, when the SOD terminal becomes ''0'', the emulator 11 stops executing an instruction, and is not operated until ''0'' is inputted to the RUN terminal next time. Also, bus drivers 21, 22 are inhibited, and 20 and 23 become effective. Accordingly, the MPU10 is capable of reading and writing the contents of a program memory 19.

Filed: 1987-03-31
Abstract: PURPOSE:To control a stepping motor in a closed loop having smooth acceleration/deceleration by using a normal stepping motor having no rotation detector by detecting the rotating position of a rotor from the phase voltage of a stator winding. CONSTITUTION:A phase voltage comparator 15 compares the voltages of phases with a reference voltage applied from a level switching circuit 16, and outputs a discrimination signal of the result to a clock circuit 13. The circuit 13 outputs an stepping signal to a distributor 12 when the phase voltage of the phase to be excited next crosses the reference voltage on the basis of the discrimination signal from the comparator 15, an excitation signal from the distributor 12 and an operation state signal from a CPU 14, and switches the exciting phase.

Filed: 1983-05-11
Abstract: PURPOSE:To prevent a leaf-like paper body from curling with a head device with elements for reading, recording, etc., by installing a rugged part in a projecting part covering the elements in the vicinity of the elements. CONSTITUTION:A wear resisting protective glass film 104 which protects elements is formed in such a way that carrying-in side of recording paper P is thickly formed and a rugged part DC which almost corresponds to the projected shape of a heating element 103 is formed in the contacting area of a platen roller 130 in the vicinity of the heating element 103. Since the recording paper P passes between the rugged part DC and platen roller 130 before passing through the heating element 103 section, the recording paper is curled in the opposite direction and, therefore, the paper is prevented from curling toward the printing side.
