Title: Formation of metallic film onto transparent conductive film
Inventor: ADACHI KOHEI
IPC: C25D5/06
Filed: 1985-11-21
Abstract: PURPOSE:To electroplate a metallic layer having excellent adhesiveness to a desired film thickness by subjecting a transparent conductive film on a transparent insulating substrate consisting of glass, etc., to electroless plating then moving electrolyte absorbed cotton attached to the periphery of an anode back and forth and energizing the anode without using a plating cell. CONSTITUTION:An Ni-P alloy 5 is electroless plates on the transparent conductive film 2 of In2O3, SnO2, etc., patterned on the surface of the transparent glass substrate 1. A negative electrode of a DC power source 11 is attached to an Ni-P electroless plating film 5 and the positive electrode of the power source 11 is attached to the anode 6 for electroplating. The cotton 7 absorbed and impregnated with a plating liquid of Cu, Au, Ag, etc., is attached to the top end thereof. A rod 8 which is electrically insulated by an insulating washer 9 from the anode 6 is moved back and forth, by which the plating liquid absorbed cotton 7 as the anode is energized while said cotton is moved back and forth on the Ni-P plating film as the cathode. The uniform metal plating film 13 having the excellent adhesiveness is thus formed by electroplating.

Title: Resonator type semiconductor luminous device and manufacture thereof
Inventor: YAMAMOTO YOSHIHISA
IPC: H01S5/00
Filed: 1991-09-13
Abstract: PURPOSE:To heighten efficiency of combining spontaneous emission from a semiconductor luminous layer with a laser mode by making a reflection film to have an outwardly expanding curved part to the semiconductor luminous layer. CONSTITUTION:Since a reflection film 3 has a curved part 3A outwardly expanding to a semiconductor luminous layer 1, combination of spontaneous emission from the semiconductor luminous layer 1 with a laser mode has also a portion slanted to the semiconductor luminous layer 1 in addition to a portion vertical to the semiconductor layer during spontaneous emission. Consequently, efficiency of the spontaneous emission of combining with a laser mode can be obtained remarkably high. Accordingly, in the case spontaneous emission is obtained by incidence of light for excitation from the outside on the semiconductor luminous layer 1 in order to obtain laser light, no large value of light for excitation or a current for excitation is required for obtaining said laser light.

IPC: H01L23/50
Filed: 1992-09-03
Abstract: PURPOSE:To prevent deformation of a lead terminal of a surface mount type electronic component and enhance the reliability of a soldered area of the lead terminal as well.

Title: Parallel adder
Inventor: HARADA KANJI
IPC: G06F7/505
Filed: 1990-09-30
Abstract: PURPOSE:To carry out the addition of two numbers consisting of m-bit binary numbers with delay of a 2m-stage gate by providing an odd step arithmetic means and an even step arithmetic means which carry out the prescribed operations respectively. CONSTITUTION:When the binary numbers A (=amam-1...a2a1) and B (=bmbm-1...b2 b1) of the m-bit length are added together, ai + bi (ENOR1i) of an i-th bit (i = 1, 2...m) and ai X bi (NAND1i) are calculated. In this case, the arithmetic result of a1 + b1 is identical with the arithmetic result of the lowest rank bit. Then ENOR1i + NAND1(i - 1) (NOR2i) and ENOR1i + NAND1(i - 1) (NOR2i) are computed between ENOR1i and NAND1(i - 1). In this case, the arithmetic result of ENOR12 + NAND11 is identical with a 2nd bit arithmetic result. Thereafter the operations are carried out by an odd step arithmetic means when the number (n) showing the steps is odd and by an even step arithmetic means when the number (n) is even respectively. Thus a critical path is equal to 2m. As a result, the arithmetic operations are carried out at a high speed.

Title: Magnetron device
Inventor: KUROKUZUHARA MAMORU
IPC: H01J23/34
Filed: 1990-10-03
Abstract: PURPOSE:To constantly let a cathode of a magnetron maintain a normal electron emission function, and to constantly let the magnetron carry out a normal oscillation work by increasing or decreasing an impedance value of a variable impedance device correspondent to the degree of the output specification value of microwave power of the magnetron. CONSTITUTION:A variable impedance device is inserted from a low-voltage winding 42 into a circuit that supplies current to the cathode of a magnetron 5, in series, and the impedance value of this device is increased or decreased correspondent to the degree of the output specification value of the microwave power of a magnetron device. The impedance value of a variable impedance device will be large when the output specification value of the microwave power is large, while it will be small when the output specification value of the microwave power is small. A cathode heating current can thus be always maintained almost at a constant value, regardless of the level of the output specification value of the microwave power, and the cathode of the magnetron can thereby always carry out electron emission sufficient enough for carrying out normal magnetron oscillation work.

Abstract: PURPOSE:To obtain a bump connection of high reliability by a method wherein, after a flat surface of a pressure material supported at a prescribed height from a semiconductor wafer has been brought into contact with bump electrodes in a pressurized state, a secure connection is executed by the bump electrodes while the bump electrodes are heated and melted with a view to achieving the prescribed bonding strength uniformly. CONSTITUTION:A water 12, where two or more bump electrodes 11 are formed and a flux- coated film is formed, is put on a bump-correcting jig 13 and a holding plate 13-1. The height of a frame material 13-2 is the same as that of the top of the previously formed bump electrodes 11. A pressure plate 13-3 with the prescribed weight is mounted on the bump electrodes 11 of the wafer 12. The plate does not touch the bump electrodes 11 whose height is low due to the irregularity of the height of the bump electrodes 11. The bump-correcting jig 13 where the wafer 12 is accommodated is put in a thermostatic heating furnace of the like and is heated. The surface of the bump electrodes whose height is higher is melted by heating, and the pressure plate 13-3 is brought into contact with the frame material 13-2. As a result, all the bump electrodes 11-1-11-6 are brought into contact with the pressure plate 13-3, and their height becomes the same as the height of the installed frame material 13-2. The wafer 12 is cut into unit semiconductor devices to form individual semiconductor chips.
