Patent JP-2003033001-A (JP)
Title: Main circuit conductor and power converter
Inventor: KATO MASASHI
IPC: H02M7/537
Filed: 2001-07-09
Abstract: PROBLEM TO BE SOLVED: To decrease the rate of change di/dt of short-circuit current when a short-circuit fault occurs, by increasing the inductance of a main circuit conductor when the short-circuit fault occurs. SOLUTION: Currents of the same magnitude flow in directions reverse to each other in a pair of conductors 1a, 1b. A movable portion 5 holds the conductors 1a, 1b in parallel in such a way as to be movable. Springs 3 urge the conductors 1a, 1b in directions for an insulator 2 to be interposed inbetween. The urging force of the springs 3 is smaller than repulsive force generated between the conductors 1a, 1b by electromagnetic force by short-circuit current which flows in the conductors 1a, 1b, when a short-circuit fault occurs. When normally operated, the conductors 1a, 1b touch the insulator 2 and their gaps become narrower, and the inductance of the main circuit conductor 10 becomes smaller. When the short-circuit fault occurs, the conductors 1a, 1b open and their gap becomes wider, and the inductance of the main circuit conductor 10 becomes larger.

Filed: 2001-07-16
Abstract: PROBLEM TO BE SOLVED: To provide a MOS reference voltage circuit having a small temperature drift (voltage change due to a temperature) of a reference voltage, and to provide a method for manufacturing the same. SOLUTION: The method for manufacturing the MOS reference voltage circuit comprises a step of deciding an impurity dose (Dep Dose amount Xd[×10<12> cm<-2> ]) at the time of ion implanting when an n-type layer 6 of a channel of a depletion type n-channel MOSFET 21 is formed according to a formula of 0.9×[[Tm+(1.75Ld+230)]/(0.3Ld+149)]<=Xd<=1.1×[[Tm+(1.75Ld+230)]/(0.3Ld+149)].
