Title: Manufacture of semiconductor device
Inventor: NAKANO HIROBUMI
IPC: H01L29/812
Filed: 1992-08-20
Abstract: PURPOSE:To improve breakdown voltages of a gate and a drain by forming an operating layer by ion implanting only at a bottom of a groove, forming a sidewall on the inner wall of the opening, masking the opening and forming a high concentration implanted layer on a semiconductor substrate. CONSTITUTION:With resist pattern C7 as a mask a thin film 6 is etched, a groove is formed on a semiconductor substrate 1a, and Si<+> or the like is ion implanted in the bottom of the groove to form an operating layer 1b. Then, the pattern C7 is removed, an insulating film is deposited on the entire surface, and then a sidewall 8 is formed. Thereafter, after the entire surface is coated with a resist pattern D9, it is etched back, and a groove part is flattened. Then, the film 6 is removed, and then a high concentration implanted layer 1c is formed by ion implanting. Thus, an electric field is concentrated at the end of the groove thereby to alleviate a concentration of an electric field at the end of a gate electrode, the concentration of the electric field hardly occurs at the end of the operating layer, and a withstand voltage of the gate is improved.

IPC: H01L21/425
Filed: 1985-11-05
Abstract: PURPOSE:To obtain such a new semiconductor material that the state of electronic energy can be controlled by modulating the structure of a host crystal using an ion-implantation method. CONSTITUTION:Implantation ions 2 are implanted into a surface (001-plane) of a layer of a laminar host crystal III-VI compound 1 at an angle inclined about 7 deg. from the vertical direction [direction of a C axis (a)].

Filed: 1991-09-26
Abstract: PURPOSE:To prevent the generation of the rust of ferromagnetic metallic thin films formed on the butt surfaces of magnetic cores in the process for production of the magnetic head of a metal-in-gap type. CONSTITUTION:Track grooves 4 and a winding groove 7 are worked on a ferrite plate (core material) 1 (A) and the ferromagnetic metallic thin film 3 is formed on the surface to be worked (B).

Title: Data communication system
Inventor: TAKAI MAMORU
IPC: H04L29/06
Filed: 1989-09-22
Abstract: PURPOSE:To eliminate a control signal such as a clock signal and a strobe signal, etc., by preparing an encoding code with plural digits of a number of 2 to the m-th power in which the value of each adjacent digit is different, and returning a confirmation value to a transmission side by changing sequentially at every reception of one digit at a reception side. CONSTITUTION:Since communication lines 19 and 20 consist of two bits (m=2), the encoding code can take the values 0-3 setting the 2 squared = 4 as one digit. And an encoding code table comprised of the encoding code is generated. The encoding code changes the value sequentially at every digit. Thereby, since the fact that the next data is sent can be recognized, the reception side transfers the confirmation value by changing sequentially at every reception of one digit without neccessitating the control signal such as the strobe signal, etc. Synchronism with the forefront of data can be obtained by taking a leading value decided in advance as the forefront of the encoding code.

Title: Method and apparatus for recognizing part in surface mounter
Inventor: MINWA TSUYOSHI
IPC: H05K13/04
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To more effectively inspect a displacement in sucking of a part by defining the projection width detection region in a light receiving portion based on the maximum displacement of a part in a packet from a reference position. SOLUTION: When the state of a sucked part is checked with a laser unit 30, a window W is set based on the maximum value of an error to be produced by the displacement of the part in a pocket on a tape and a mechanical error, and thereby the part can be projected within a range of part suction error which is actually produced. In other words, the width of the window W is set to the minimum value required in the detection of part projection width. Accordingly, when the projection width of the same part is detected, the size of the window W can be reduced by an amount indicated by width Wa, for example. Therefore, the output signals from a detector 31b to be processed in the projection width detection can be reduced, and thereby a contribution to the inprovement of the part recognition efficiency can be done.

Abstract: PURPOSE:To identify existence of an obstacle and its location by a method wherein a sensing code indicating whether or not data transmission between sensing stations and relay transmitters has been normally performed is set in a data frame with tokens and sequentially transferred. CONSTITUTION:Sensing stations S1, S2,...S400 are placed at equal intervals on a side wall 3 while relay transmitter T1, T2,...T400 are placed with equal intervals on a side wall 4.
