Title: Improvement of adhesive property between copper foil and resin
Inventor: MASUI KATSUE
IPC: C23G1/10
Filed: 1989-03-13
Abstract: PURPOSE:To improve adhesive properties between a resin and a copper foil by forming a film of copper oxide on the surface of the copper foil, dissolving and removing the oxide film formed on the surface with an acid and thereby roughening the surface of the copper foil when the copper foil and the resin are heat-pressed. CONSTITUTION:When a copper foil and a resin are heat-pressed, after a film of copper oxide is formed on the surface of the copper foil, the oxide film is dissolved and removed by means of a chem. treatment with an acid and the surface of the copper foil is thereby roughened to improved adhesive properties between the copper foil and the resin. As copper oxide is easily dissolved by means of an acid hydrolysis compared with copper, when acid treatment is performed after the oxide film is formed, only the oxide layer is selectively dissolved and removed and a roughened copper surface appears. As the thickness of the copper oxide film is scores to thousands Angstrom , there is no possibility that all the copper foil is converted to copper oxide and then dissolved and removed. Adhesive properties between a conductive metal and the resin can be improved by this method and peeling of a resist pattern, getting into inside of a plating, infiltration of a plating liq., peeling and crack caused by thermal and mechanical shock, an interlaminar peeling of the inner conductive body and a prepreg can be prevented.

Title: Operation processor
Inventor: NAKAJIMA MASAHIRO
IPC: G06F9/44
Filed: 1988-03-14
Abstract: PURPOSE:To save trouble for writing arithmetic definition by developing arithmetic resulted value in the arithmetic definition and executing an arithmetic operation by only data of a first storage means, when other arithmetic resulted value is contained in one arithmetic definition. CONSTITUTION:When a TAG for showing other operation result is detected in an operational expression, an operation processing part fetches its arithmetic definition from a second storage means, and develops it in the original arithmetic operational expression. Since the operation is executed by only the existing data stored in the first storage means, trouble for writing the same arithmetic data many times is removed.

Filed: 1980-05-07
Abstract: PURPOSE:To improve the distortion characteristics at a low band, by providing a sliding element at the position which is opposite to both surfaces of a plate or both surfaces of the plate of a pole piece and then supplying an aural current to a voice coil through the sliding element. CONSTITUTION:A sliding element 12 is provided at the position opposite to the inner circumference surface of a plate 2 and at a part of a pole piece 1. An aural current is supplied to the element 12 via a lead wire 13, and thus the aural current is supplied to a voice coil 4d through the element 12. The aural current is always supplied to the coil 4d only at a part (c) which is held between the upper and lower elements 12 regardless of the position of the coil 4d. In this connection, the coil 4d never swells out over the concentrated part of magnetic flux by setting the winding width of coil 4d slightly larger than the required maximum amplitude. Thus the occurrence of distortion can be reduced.

Title: Vapor growth equipment
Inventor: IGA HIROSHI
IPC: H01L21/31
Filed: 1985-03-25
Abstract: PURPOSE:To keep uniform temperature distribution over a substrate when it is heated for preventing the slippage and to obtain a vapor growth layer having a more uniform thickness, by providing the portion of a susceptor where the substrate is to be disposed with a through hole having a size approximately equal to or smaller than that of the substrate so that the susceptor supports the outer periphery of the substrate directly or indirectly. CONSTITUTION:A carbon susceptor 10 arranged within a reaction chamber 2 by means of a support table 11 of quartz is provided with a through hole 12 having a size somewhat smaller than that of a substrate 4. The substrate 4 is disposed at the upper end of the through hole 12 such that the top face of the substrate 4 lies on the approximately same level with that of the susceptor 10. When the entire surface of the substrate 4 is uniformly heated by means of radiant light from a lamp 5, heat is dissipated more from the outer periphery than from the central portion of the substrate. It can cause the outer periphery to have a temperature lower than that of the central portion. In fact, however, the outer periphery is heated by the heat conduction from the susceptor 10 and the radiation so that a uniform temperature can be kept over the entire substrate 4.

Abstract: PURPOSE:To improve the whole working efficiency by letting a normal carrier truck transferring a load continue its action, making the normal carrier truck which is not transferring the load take refuge in the nearest refuging line, making the carrier truck which loses the present address circulate on a loop line to recover a new present address. CONSTITUTION:When a carrier truck 1 losing a present address is generated, the winding-up carrier tuck 1, to which a destination address is not set, is made to refuge to the nearest refuge line 7. Then, by making the carrier truck 1 losing the present address wind up on a loop line 2 smoothly and pass an origin 3, the carrier truck 1 can be made to recover the present address, and a destination address is set, the destination address can be moved. Besides, the carrier truck 1, which is transferring a load or is moving to a first destination address to receive the load at working generating, continues to move as it is. Thus, since the transfer of the load is not delayed and moreover the carrier truck 1 losing the present address is made to wind up without being stopped, the delay of the carrier truck 1 can be eliminated and the whole working efficiency can be raised.

Abstract: PURPOSE:To effectively reduce the flicker of screen caused by the fluctuation of the transmissivity, etc., of a liquid crystal display pannel by controlling electric field applied to a liquid crystal so that the fluctuation in the output of a photodetector detecting a light quantity transmitting through the liquid crystal display pannel becomes a minimum. CONSTITUTION:This device is provided with the liquid crystal display pannel 7 and a light source device 9. Further, the device is provided with the photodetector 13 detecting the light quantity transmitting through the liquid crystal pannel 7 and a means 10 controlling the liquid crystal display pannel 7 or the light source device 9 so that the fluctuation in the output of the photodetector 13 becomes a minimum as the constitution eliminating the flicker of the screen. The flicker occurs due to that the transmissivity of the liquid crystal display pannel 7 is fluctuated due to the shift in DC of the +- electric field in the liquid crystal occurring when the liquid crystal is AC driven. Then, the fluctuation in the transmissivity of the liquid cryatal display pannel 7 being the cause of the flicker is detected as the fluctuation in a photoelectric current by the photodetector, and the electric field applied to the liquid crystal is controlled so that the fluctuation in the output of the photodetector becomes a minimum. Thus, the deviation in DC of the +-electric field in the liquid crystal is normalized to a minimum, and the flicker is reduced.

Abstract: PROBLEM TO BE SOLVED: To reduce a data amount while maintaining the acceleration of a processing speed by displaying a vertex that is common to plural polygons with coordinate data of one vertex and its positional data. SOLUTION: Polygon data, etc., stored in an external storage medium are read from an I/O 13 by the control of a CPU 11 and is stored in a data memory 16 through a data control circuit 15. The stored polygon data converts a vertex coordinate of a polygon that is arranged at a view port by such a manner that the CPU 11 executes geometry processing into a three-dimensional coordinate in a view point coordinate system that makes a prescribed view point coordinate a reference based on the control of the circuit 15. The vertex coordinate data that undergoes geometry processing is once stored in a cache memory 14. Then, when an overlapping vertex coordinate exists, it is possible to reduce a polygon data amount by reading vertex coordinate data of a position indicated by the CPU 11 from the memory 14.
