Title: Inverter circuit
Inventor: MIYACHIKA EIJI
IPC: H02M7/537
Filed: 1982-04-07
Abstract: PURPOSE:To protect a transistor without necessity of a dead time controller by bypassing a current which is generated by the counterelectromotive force at the OFF time of a switching transistor. CONSTITUTION:When a voltage is not applied to the base of a transistor TR1, the transistor TR1 becomes OFF state, and an input voltage E1 is not applied to the primary coil of a transistor T1. At this time the current flows through diodes D2, D1, the reset coil of the transformer Tr, and the input power source E1. If an ON voltage VB is applied to the base of the transistor TR1 during the reset of the transformer T1, the transistor TR1 is reversely biased by the forward voltage drop of a diode D2. Accordingly, the transistor TR1 may not become ON state. In this manner, the transistor TR1 can be prevented from being damaged.

Abstract: PROBLEM TO BE SOLVED: To prevent damage due to spattering of a plasma torch, a machine main body, etc., in piercing, to enable piercing in a thick plate and to improve machining efficiency. SOLUTION: A pilot arc Ap is generated from a plasma torch 27 to a work W in the case of starting piercing, the generating output of a plasma arc is increased and then the plasma arc is transferred from the pilot arc Ap to a main arc Am. As the generating output of the main arc Am is gradually increased, while a height of the plasma torch 27 for the work W is gradually raised from near the surface of the work W, a gas Gc from a gas injection nozzle 37 is blown to the plasma arc of the main arc Am from the horizontal direction, and thereby the plasma arc is intentionally bent/deformed. Thus, a piercing hole PH is not pierced right under a nozzle 29 of the plasma torch 27, the plasma torch and the machine main body is protected from spattering SP.

Filed: 1989-03-10
Abstract: PURPOSE:To increase a value of a critical current by forming a pattern of a magnetic thin film to a front surface or a rear surface of a superconductor thin film and by forming a flux pinning element. CONSTITUTION:A pattern 4 of a magnetic thin film is formed at least to a front surface or a rear surface of a superconductor thin film 7 to realize a structure having a flux pinning element. An artificial fluxoid pinning pattern through ferromagnetic body is thereby formed in this way. If an intense space gradient is provide to the fine line pattern density, an artificial resistance force is produced against a force of a fluxoid to move. A maximum value of a superconductive transportation current is decided by a maximum allowable value of a space density gradient of a fluxoid which has entered a thin film. According to this constitution, a remarkable increase of a superconductive critical current can be realized at a critical temperature or below if conditions to support a density gradient of a fluxoid are arranged artificially.
