Title: Inverter controlling device
Inventor: KAWAMURA HIROTOSHI
IPC: H02M7/48
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To prevent voltage that is equal to or more than 1/2 of a DC bus voltage from being applied to a switching element by limiting the change in a voltage command smaller than the amplitude of a carrier within a cycle of limitation where each switching element is turned on and off. SOLUTION: An amplitude-limiting means 24 functions to obtain a voltage command Vu1 where voltage command is limited smaller than the amplitude of carriers Ec1 and Ec2 within a predetermined cycle of limitation, where first to fourth switching element 13-16 are turned on and off by inputting a voltage command Vu to an amplitude limitation circuit. Therefore, with the voltage command Vu1 and to carrier signals Ec1 and Ec2 as input, a control circuit 23 compares each of the carrier waves Ec1 and Ec2 for the voltage command Vu1 and performs each delay processing of the two comparison outputs and inverted output for preventing short-circuiting due to the arc extinction delay of the switching elements 13-16.  After that, gate signals G1-G4 are inputted to a gate terminal for on/off operation, thus preventing voltage that is equal to or more than 1/2 of a DC bus voltage from being applied to the switching element.

Abstract: PURPOSE:To simplify a process and improve photoelectric conversion efficiency by a method wherein two layers of p-Ga1-xAlxAs are formed on an n-GaAs single crystal and mixed crystal ratio x of each layer is changed according to a specified manner. CONSTITUTION:An Au-Ge-Ni alloy electrode 1 is formed on one side of a substrate 2 of material such as Si, II-VI family or III-V family compound semiconductor. On the side of the substrate 2, n-GaAs 3, Be-doped p-Ga1-xAlxAs4 where 0.85<=x<=1 and Be-doped p-Ga1-xAlxAs6 where 0.5<=x<=0.75 are piled and an SiO reflection preventing film 7 and an Au-Be alloy electrode 8 are formed. A P-N junction 5 is shifted from the boundary of the layer 4 by thermal diffusion from the layer 4, so that carrier recombination is avoided by crystal defect generated at the boundary and photoelectric coversion efficiency is improved. Moreover, formation of an electrode becomes easy by taking carrier density of the layer 6 large enough, for instance not less than 10<18>/cm<3>, and resistivity is reduced, so that current loss is eliminated. With above configuration, an antioxidizing film is not necessary and total efficiency is improved to 20% or above.

Title: Lc filter
Inventor: KAWAGUCHI MASAHIKO
IPC: H03H7/01
Filed: 1987-07-22
Abstract: PURPOSE:To make the constitution small in size by using a resin with a magnetic substance contained therein to pack the entire dielectric base, thereby increasing the inductance without increasing the number of turns of a printed coil. CONSTITUTION:High frequency ferrite powder is mixed in the resin 16 packing the filter main body. The package by the resin 16 is applied to surround the entire filter main body.
