Title: Power converter
Inventor: NAKAZAWA YOSUKE
IPC: H02M7/12
Filed: 2002-11-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide an economical power converter which can reduce the higher harmonic of the whole system in a parallel operation with an existing power diode rectifier and also is excellent in overload resistance, capable of power regeneration and high in converter efficiency.  <P>SOLUTION: At power running, by limiting an input current I of a power converter CNV, a DC voltage Vd drops in the case that a load over its limitation value is applied to it, and power is supplied from a power diode rectifier REC, and the power diode rectifier REC (equivalent to six phases) and the voltage type self-excited power converter CNV (equivalent to six phases) are operated in parallel. At this time, there is a phase difference of 30° between transformers TRa and TRb, so that it becomes twelve-phase operation equivalently, and the higher harmonic of the input current of the whole device decreases.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To highly accurately control the threshold of a memory cell transistor by increasing an gradient angle of injection in ion injection for setting the threshold of the memory cell transistor which may be difficult in accordance with miniaturization.  <P>SOLUTION: After forming a multilayer gate electrode 21 in a memory region Rmem, a silicon oxide film 11 is formed on the whole surface. In forming a p-type region 16 by ion implantation 15 in order to set the threshold of the memory cell transistor after forming a heavily doped n-type source region 14, the height of a resist pattern 12 obtained by opening a source region which becomes a mask is set lower than the height of the multilayer gate electrode 21. Even when the memory cell transistor is miniaturized, the gradient angle θ of the ion implantation 15 can be increased independently of the film thickness of the resist pattern 12, and the threshold of the memory cell transistor can highly accurately be controlled.  <P>COPYRIGHT: (C)2004,JPO
