Title: Vertical mos field effect transistor
Inventor: TANIDA HIROSHI
IPC: H01L29/78
Filed: 1987-12-29
Abstract: PURPOSE:To improve breakdown strength, and to miniaturize a pattern by forming an opposite conductivity type diffused layer having a deeper diffusion length than that of a channel forming region around a plurality of opposite conductivity type channel forming regions, and crossing the outermost part of the channel forming region across the diffused layer. CONSTITUTION:A F.L.R.(field limited ring) 9 having a deep diffusion length by boron ion implantation and a deep diffused layer 10 of a deep channel forming region are so formed as to surround all a plurality of opposite conductivity type channel forming regions 4 to a silicon substrate to become the drain region 1 of a vertical MOS field effect transistor, and the diffusion length of a P-type region is deepened by high temperature treating. Thereafter, after a gate oxide film 2, a polycrystalline silicon 3 are generated, with the silicon 3 as a mask a channel forming region 4 and a source region 5 are diffused in a self-alignment by boron/phosphorus ion implantations. Thus, the reverse breakdown strength of the power MOSFET is enhanced, and a pattern can be miniaturized without varying a region except the MOS pattern such as the F.L.R part 9.

IPC: H01R43/00
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a connector inspecting apparatus which can enhance workability in inspecting connectors. SOLUTION: A connector receive part 7 has a receiving recess 17.

Abstract: PURPOSE:To rigidly connect a lead by forming a step of a second layer made of tungsten or molybdenum on a ceramic board pattern, and circulating silver brazing material to the step at the time of connecting the lead. CONSTITUTION:A first layer 12 made of tungsten is printed and formed corresponding to a predetermined pattern on a ceramic board 10 so that the end is disposed inside the board 10. Then, a second layer 14 made of tungsten or molybdenum is formed by forming a step H and superposing the part of the step on the board 10. Then, when it is nickel plated 16, a lead 18 and a silver brazing material 20 are placed, press-bonded and heated, the silver brazing material is circulated to the lower part of the lead 18 by its own weight, and connected completely in a state that a silver brazing material reservoir is formed. Thus, a connecting strength can be enhanced by avoiding a stress concentration for the metallized part or the board.

Title: Power converter
Inventor: SUGIURA YASUYUKI
IPC: H02M7/155
Filed: 1993-12-28
Abstract: PURPOSE:To enable a no-break operation by decomposing voltage signals for three phases of an AC power source into the respective components of the real axis and the imaginary axis, detecting the phase of a positive phase sequence from the respective components by using an instantaneous symmetric coordinate method and defining the phase of the positive phase sequence as a voltage phase. CONSTITUTION:A phase angle detector 118 decomposes the voltage signals for three phases of an AC system 101 into the respective components of the real axis and the imaginary axis and detects the phase of the positive phase sequence from the respective components by using the instantaneous symmetric coordinate method. Then, the phase of the positive phase sequence from the phase angle detector 118 is defined as the voltage phase. Thus, even when one line inside the AC system 101 commits a ground fault and the voltage becomes zero, the phase is highly accurately detected and the operation is stably continued without stopping a power converter 103 by controlling the power converter 103 based on the detected phase.

Title: Picture input output device
Inventor: SHIRAISHI MASAYOSHI
IPC: H04N1/04
Filed: 1991-12-18
Abstract: PURPOSE:To detect a size of an original accurately without being affected by noise or a type of the original by comparing at least two color picture data subject to color separation with reference data. CONSTITUTION:A picture read means 3 separates read picture data into 3 RGB colors and inputs the result to a signal processing means 4. The means 4 converts the received analog signal into a digital signal and it is inputted to a discrimination means 6. An original area detection means 8 discriminates whether an original 1 is read or an original detection plate 2 is read based on a level of an output signal 12c of the means 6. When the detection plate 2 is discriminated, the processing is terminated. When the original 1 is discriminated, a coordinate signal 15 and a minimum coordinate are compared, and when the signal 15 is smaller than the minimum coordinate, the signal 15 is stored as the minimum coordinate and when not, the signal 15 is compared with a maximum coordinate, and when the signal 15 is larger, the signal 15 is stored as the maximum coordinate. When the signal 15 is larger than the minimum coordinate and smaller than the maximum coordinate, no processing is implemented. Thus, the size of the original is detected accurately.

Filed: 1992-12-17
Abstract: PURPOSE:To exactly read only the surface to be read at high speed by switching the color of the plane of an original presser board in contact with an original to any dark color by using a color switching means. CONSTITUTION:An original presser sheet 12 forming the presser plane of an original presser board 5 is formed composed with a white color part 12W and a dark color part 12B having a length corresponding to a distance between both of rollers 15 and 17. At the time of reading thin paper copied on both sides as an original, the original presser board 5 is closed so that a knob can be inserted to the engagement recessed part of the main body of the device, and the color of the presser board 5 on the presser plane side is switched to the dark color part 12b. Thus, even when the quantity of light irradiating the original is massive, the light transmitted through the original and made incident on the dark color part 12B of the original presser board 5 is not reflected but absorbed by the dark color part 12B. Therefore, the surface opposite to the reading surface of the original is not read together with the surface to be read.
