IPC: H01L29/78
Filed: 1995-03-27
Abstract: PURPOSE: To improve reliability, handling properties, manufacturing properties, and cooling efficiency, by metallographically joining the cathode electrode and the anode electrode of an MOS controlled power semiconductor element to a cathode side inner electrode and an anode side inner electrode. CONSTITUTION: A cathode electrode 303 and a collector electrode 304 of an Si substrate 301 are rigidly metallographically bonded to inner electrodes 307, 308. A gate electrode 309 arranged around an IGBT is connected with a gate terminal 311 through a wire. These are sealed with resin 313. The capacity of an IGBT is dependent also on the performance and the size of the Si substrate, and about 500-3000V and 50-300A. In the range of this capacity, application in this state is possible. Since the cathode electrode and the collector electrode of the IGBT are bonded to the inner electrodes 307, 308, heat can be made to escape from both sides. Thereby the thermal resistance and the reliability are improved and a wire bonding part is hardly deteriorated.

IPC: H04L1/22
Filed: 1982-04-23
Abstract: PURPOSE:To change respective internal states to the same state with two control circuit outputs executing the same control by constituting a titled so as to output by two sets of data processors complementarily with a device selection signal given from the outside. CONSTITUTION:Since data processors 20, 21 output complementarily with a device selection signal 100 given from the outside, when one is making an output, the other is waiting for the operation. Thus, output data of, e.g., the data processor 20 in operation is outputted to an output terminal 101. Then, control circuits 10, 11 change the internal state of the data processors 20 and 21 with the same control based on the output data and the internal state of the data processors 20, 21 is controlled in the same state. In this case, the device selecting signal 100 brings the processor 21 to an outputting state and the processor 20 to a waiting state, and even if the device in operation is replaced, since the internal state of the processor 21 is changed suitably based on the preceding output data already, the operation is done continuously.

Title: Forming method of pattern
Inventor: HIRAI YUTAKA
IPC: H01L49/02
Filed: 1984-04-06
Abstract: PURPOSE:To enable the control of two-dimentional arrangement of a monomolecular film or a monomolecular accumulated film, by scanning the surface of a substrate by means of energy beams, and by forming then a pattern to form the monomolecular film or the monomolecular accumulated film. CONSTITUTION:On the surface of an Si (100) plate 1-1, for instance, a monomolecular accumulated film 1-2 of arachidic acid is formed by the LB method to prepare a substrate. Next, the surface of the substrate is scanned by an argon laser condensed into a radius of 50mum. Thereby an arachidic acid film in a scanned part 1-4 is degenerated and vaporized and thus a pattern is formed. Then, a monomolecular accumulated film of the derivative of arachidic acid and merocyanine is formed by the LB method. Concretely, a solution prepared by dissolving said acid and derivative in chloro-form is developed on the surface of water and then deposited in an layer. A monomolecular accumulated film 1-5 is not formed in the part 1-4, but formed only in a part 1-3 in accordance with the pattern.

Filed: 1993-03-03
Abstract: PURPOSE:To prevent a flicker from occurring by preventing a lighting display frequency from lowering even when a dark image is displayed on a matrix display pannel. CONSTITUTION:In a method of time dividing one frame display interval for every pixel to eight pieces of sub-field intervals SF1-SF8 corresponding to the display gradation with eight bits, and weighting corresponding to every bit in every interval and displaying a halftone image, the time sequential alignment of N pieces of SF1-SF8 is formed to the alignment where SF1, 3, 5, 7 whose weighting are small, are diffused time sequentially by taking out one by one from an increasing order alignment 1, 2, 4 and a decreasing order alignment 128, 64, 32 successively alternately as shown in the figure. Thus, in the lighting display distribution of a bright image, all SF1-SF8 become a lighting display interval as (a), and in the lighting display distribution of a dark image, four pieces of SF1, SF3, SF5, SF7 whose weghting are small become the lighting display interval as (b), and the interval is not converged as conventinal one but diffused.

Title: Gear grinding method
IPC: G05B19/4103
Filed: 1992-03-26
Abstract: PURPOSE:To provide a method which can use a gear bias grinding method by means of numerical control even in the case of an arc interpolation curve having a very large radius of curvature. CONSTITUTION:Relations between a rotation angle Arev around an axis A and a movement stroke Zst in the direction of the axis Z of a gear to be ground which is ground by a rotating grindstone are subjected to arc interpolation to perform bias working. In this case, arcs indicating the range of a minimum resolution DR are determined on both sides of the arc interpolating curve, and a line tangential to the inner arc is drawn from a start point P0, and rectangular coordinate values of a point P1 where this line and the outer arc intersect are obtained. Rectangular coordinate values of a point P2, and following points 10 are obtained in the same manner to generate a set of lines obtained by decomposing the arc interpolating curve into minute segments in the range of the minimum resolution DR. Relations between Arev and Zst are controlled by rectangular coordinate points determining respective segments to grind an involute gear. Even if the radius of curvature of the arc interpolating curve exceeds specifications of an NC device, the arc interpolating operation can be controlled by minute segments approximated to an arc.

IPC: G01S19/27
Filed: 1985-03-30
Abstract: PURPOSE:To shorten the time needed for data collection, and to measure the position even in the case of the signal from the satellite is shielded by the building, etc., by dividing and collecting the Ephemeris data into the word unit and holding them at the memory. CONSTITUTION:The signal of the satellite received from an antenna part 1 enters a receiving part 12, demodulates the navigation data, measures the pseudo range, and stores successively to a buffer 13 for the data bit. Here, when the data can be demodulated, the symbols '0' and '1' are stored by the polarity of the data, and when the electric wave is shielded and the data can not be modulated, for example, '2' is stored as the mark for identification. A data bit processing part 14 processes the data of the buffer, stores them to a memory 15 for the decoding data and uses a word collecting flag 16 at the time of the processing. A position measuring calculating part 17 obtains the position of the satellite from the navigation data of the memory 15 for the data, assembles with the pseudo range, constitutes the navigation equation which is usually well known, solves it, obtains the position of the user and outputs this to a displaying device 18.
