Title: Transformer controller
Inventor: MINAGAWA TAMOTSU
IPC: H02J3/16
Filed: 1992-02-14
Abstract: PURPOSE:To prevent hunting by making a decision whether tap driving direction of one transformer is reverse to that of the other transformer and locking output of tap driving signal if a decision is made that the tap driving direction is reversed and tap driving signals for one transformer are outputted predetermined times within a predetermined time. CONSTITUTION:A logic circuit 32A makes a decision whether the tap driving direction is identical or not based on signals fed from a voltage hunting detecting means 29 and a reactive power hunting detecting sans 30 and a signal Tdv 28A for driving the tap in incremental direction. If a decision is made that the driving direction is reversed. times of detection are recorded in order to decide hunting. When the number of detection reaches a set value, the logic circuit 32A produces an output 1. When the output 1 from the circuit 32A and an output from a counter 31A are inputted to an AND circuit 33A, an output (a) is fed through a NOT circuit to an AND circuit 24A which thereby produces a 0 output and that state is locked thus locking tap driving on the side where hunting has occurred.

Abstract: PURPOSE:To improve the pressure resistance between an impurity layer and a substrate by giving an etching in advance on the substrate surface of the region where a shallow impurity-layer is to be formed. CONSTITUTION:A field oxidized film, an Si oxidized film 13 and a polycrystalline Si film 14 are formed on an Si substrate 11. Then, a gate electrode 14 is formed by selectively etching the film 14. This electrode 14 obtained is used as a mask and the surface of the substrate is exposed by etching the film 13. Then, an Si oxidized film 15 is formed. This film 15 is, due to the difference in preparatory formation, thin on the surface of the substrate 11 and thick on the surface of the film 14. Then, an etching is given until the substrate 11 is exposed. Next, the surface of the substrate 11 is etched in the state that the film 14 is covered by film 15. In this case, the side of the section being etched makes a sloping surface. After that, shallow layers 16 and 17, which will become a source and a drain regions, are formed by injecting impurities. Hence, the radius of curvature of the edges of the layers 16 and 17 is increased, and the pressure resistance of the substrate 11 is improved.
