Title: Method and device for generating two-dimensional circuit pattern
Inventor: YAMASHITA KYOJI
IPC: G03F1/36
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To generate a high-accuracy multi-gradation two-dimensional circuit pattern at high speed by finding an area without extending graphic data into bits, and finding the density value of an entire graphic corresponding to that area. SOLUTION: The coordinate and dimension of a trapezoid are inputted and afterwards, the coordinate and dimension of the trapezoid are normalized in a picture element size as preprocessing. Next, a discriminating means 13 discriminates four sides of the trapezoid concerning the distances from the center of picture elements to the sides and whether the center of picture elements is located inside or outside the trapezoid and at the same time, an area means 14 calculates the area occupied by the trapezoid in the picture elements including apexes. At an image density value generating means 16 to which these results are inputted, the density values of all the picture elements included in the trapezoid are written in an image memory 17.  When the trapezoid to be processed is still remained, similar processing is performed to that trapezoid and its density value is added to the written density values. When there is no trapezoid to be processed any more, processing is finished and the result is read out as reference data.

Title: Protection device for plunger drive circuit
Inventor: INOUE SHIYOUJI
IPC: H01F7/18
Filed: 1981-12-09
Abstract: PURPOSE:To prevent troubles due to heating of a plunger by detecting such an accident that a transistor adapted to attract the plunger has been broken. CONSTITUTION:If a drive transistor 2 or a first transistor 3 is broken by some reason, the connection point between the first transistor 3 and the plunger 4 becomes high potential with first source voltage V1 and transistors 8, 9 of a detection circuit 7 are turned off, whereby base potential of a transistor 10 is raised in accordance with a time constant determined by a resistor R7 and a capacitor C1. When the raised potential conducts between base and emitter of the transistor 10, the transistor 10 is turned ON so that the output voltage of its collector drives a control circuit 1 and a second transistor 5 for holding is turned ON. Thus, the subsequent power supply to the plunger 4 is interrupted to prevent damages of the second transistor 5 and the printed circuit board.

Title: Semiconductor chip module
Inventor: NISHIGUCHI KATSUNORI
IPC: H01L23/36
Filed: 1991-08-08
Abstract: PURPOSE:To improve the heat dissipation property of a semiconductor chip module by a method wherein each one end of heat sinks is brought into contact to the central parts of the upper surfaces of semiconductor chips mounted in such a way that circuit surfaces are faced upward and an insulative thermal compound material is filled in the chips all over the surfaces of the chips in such a way as to come into contact to both of the chips and the heat sinks. CONSTITUTION:Holes 2a are bored at positions, which correspond to the mounting positions of face up type semiconductor chips 4 and face down type semiconductor chips 4a, on a chip 2. Each one end part of heat sinks 3 is inserted in the holes 2a and is brought into contact to the surfaces of the chips 4 and 4a. Moreover, an insulative thermal compound material 1 is filled in the chips 4 almost all over the surfaces of the chips 4 in such a way as to come into contact to both of the chips 4 and the sinks 3. Accordingly, heat which is generated in the center parts of the chips and I/O circuits on the peripheral parts of the chips 4 is transferred to the sinks 3 via the material 1. Thereby, a good heat dissipation design becomes possible and the heat resistance of a semiconductor chip module can be reduced.

Filed: 1984-09-26
Abstract: PURPOSE:To eliminate the variation of substrate potential by forming a substrate potential feed layer between a bipolar transistor and a MISFET. CONSTITUTION:When a bipolar transistor is saturated, a parasitic bipolar transistor Q3, which uses a base region 35 (a P type) as an emitter, an N type well region 33 (the P type) and an N<+> type buried layer 31 (an N<+> type) as collectors and a substrate 31 (the P type) as a collector, is shaped, and currents Isub flow through the substrate 30. Potential drops by a resistor R1 in the substrate 30, but a substrate potential feed layer 41 is fixed at substrate potential, thus absorbing Isub, then preventing the occurrence of potential variation in the substrate 30 under a MOSFET. Accordingly, a flowing-in up to the substrate under a MISFET of the substrate currents of the parasitic bipolar transistor is prevented, thus varying no substrate potential, then acquiring stable operation.

Title: Spindle earth contact structure
Inventor: KIMURA YUKIO
IPC: G11B19/20
Filed: 1985-09-10
Abstract: PURPOSE:To prevent the resonance of a plate spring and to eliminate the generation of abnormal sounds by absorbing the vibrating force produced by rotary sliding actions given between a spindle projection and the recess of an earth contact with the degrees of freedom of a leaf spring in its transverse and longitudinal directions. CONSTITUTION:An earth contact spring A is formed with the leaf spring 11' and an earth contact 10' having a contact with a projection provided to the spindle of a magnetic disk device. The spring 11' is bent preliminarily to secure the contact pressure and the center width of the spring 11' is reduced to deteriorate the rigidity and to reduce the spring constant. Thus the degree of freedom is secured against the width direction shown by an arrow head. As a result, the vibrating force produced by the rotary sliding actions given between the worn part of a contact and the spindle projection is absorbed by the degree of freedom of the spring 11'. This prevents the generation of resonance and abnormal sounds.

Title: Manufacture of optical integrated circuit
Inventor: FUJIWARA MASAHIKO
IPC: H01S5/00
Filed: 1982-11-16
Abstract: PURPOSE:To manufacture the optical integrated circuit, which is manufactured easily, in which a coupling at high efficiency of both a passive waveguide and an active waveguide is enabled and which does not interfere in the operation of a device on the passive waveguide and the active waveguide, by removing upper sections at the stepped difference of a semiconductor substrate in each waveguide and an intermediate layer and forming end surfaces mutually corresponding to the active waveguide and the passive waveguide in approximately parallel. CONSTITUTION:A stepped difference 11 is formed previously on the InP substrate 1 through etching. When forming the stepped difference, various stepped-difference shapes can be selected by selecting etching liquids and substrate orientations, but the stepped difference close to verticality is preferable. An InP buffer layer 2, the InGaAsP active waveguide layer 3, the InP intermediate layer 4, the InGaAsP passive waveguide layer 5 and an InP clad layer 6 are grown continuously on the substrate to which the stepped difference is formed. The depth of the stepped difference and the thickness of the intermediate layer 4 are controlled previously so that the positions of the active waveguide layer 3 and the passive waveguide layer 5 coincide on both sides of the stepped difference at that time. The stepped difference section of the substrate is removed, and the end surfaces of the active waveguide and the passive waveguide are formed. Accordingly, beams 12 generated or amplified by the active waveguide 3 couple with the passive waveguide 5 while interposing a minute clearance removed through etching.
