Title: Manufacture of plurality of selectable power semiconductor chip
Inventor: AREKUSANDAA JIYON YAAMAN
IPC: G01R31/26
Filed: 1989-05-01
Abstract: PURPOSE: To manufacture a power chip mosaic, using the additive method, by screen-printing a polymer layer on a wafer with exposed contact pads of devices, testing the devices, burying the contact pads of rejected devices, and interconnecting accepted devices. CONSTITUTION: A polymer layer is screen-printed on a semiconductor wafer including accepted and rejected devices to form via-holes on the devices enough to expose contact pads of the devices. The devices are tested to form a rejected device location map on the wafer, the via-holes exposing the contact pads of only the rejected devices are buried to selectively choke the rejected devices according to the map. The wafer is covered with a metal layer to electrically interconnect the accepted devices, and the metal layer is patterned to form a power chip array with the accepted devices interconnected through conductive metal runs.

Title: Switching power supply
Inventor: NAGAKATA NOBUYOSHI
IPC: H02M3/338
Filed: 1989-04-28
Abstract: PURPOSE:To prevent the efficiency of an apparatus from lowering at the time of a light load by reducing the ON period of a switching means, when an output becomes a light load, and by decreasing the quantity of energy supplied to the primary winding of a transformer. CONSTITUTION:When the ON period length of a synchronous oscillation circuit 6 is narrowed at the time of a light load, the ON period length of a switching element 4 is narrowed and energy applied to a primary winding 3a and supplied to the output side via transformer 3 is decreased so that the ON period length of a secondary switching element 8 for controlling an output voltage stably also becomes narrower. Therefore, energy applied to a secondary winding 3c and regenerated on the input side via the transformer 3 diminishes also so that an electric current flowing to the primary winding 3a and secondary winding 3c of the transformer 3 is reduced.

Title: Method for forming wiring pattern
Inventor: YAMAMORI AKIYOSHI
IPC: H01L21/306
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a wiring pattern so as to improve yield by surely rounding only the edges of the wiring pattern without adding another process. SOLUTION: After forming an aluminum film 2, the aluminum film 2 is wet-etched using a resist pattern 4, which is made of phenol novolak resin photoresist, as a mask and TMAH(tetramethylanmonium-hydroxide) as etching solution. Then, adhesion of the resist pattern 4 is reduced at the interface between the resist pattern 4 and the aluminum film 2 simultaneously with the formation of the aluminum wiring pattern 5, and the resist pattern 4 floats at the interface. Thus, the TMAH aqueous solution soaks, and the edge corners of the aluminum wiring pattern 5 are etched to be rounded.

Title: Current mirror circuit
Inventor: ARIYOSHI HIROMI
IPC: H03F3/343
Filed: 1981-07-14
Abstract: PURPOSE:To keep the ratio of current mirror to 1 even to the fluctuation of temperature and load, by providing a level shift circuit making the operating point equal and a circuit compensanting the amplification factor. CONSTITUTION:Transistors (TR) TR1 and TR2 are in the current mirror operation. The collector potential of the TR1 and TR2 is level-shifted with a TR3 and made equal. Thus, the operating point of the TR1 and TR2 is equal. Then, the TR1 and TR2 are operated in the same state. Since a TR4 is connected to the collector and the base of the TR2, the impedance viewed from a load L is very high and the effect of the load current from the load L can be decreased. Further, the base current of the TR4 compensates the base current picked up at the TR1.

Abstract: PURPOSE:To enhance the density of memory cells by providing two grooves on an insulating layer between a pair of transistor regions formed in a semiconductor layer through a predetermined interval. CONSTITUTION:In a semiconductor memory, a field effect transistor is composed of a depletion layer 22a in a semiconductor layer 22, a gate insulating film 26, a diffused source layer 23, and a diffused drain layer 24 and a gate electrode 25.

Title: Single chip microcomputer for evaluation
Inventor: IKEI SATOSHI
IPC: G06F15/78
Filed: 1986-05-13
Abstract: PURPOSE:To inhibit the change of modes for a chip to be evaluated by inhibiting the access to be given to a mode switching register as long as the chip for evaluation is kept under an executing state of a program to be evaluated. CONSTITUTION:The working state output signal 8 for evaluation chip is kept at a high level under execution of a program to be evaluated by the evaluation chip. Thus the output 10 of an OR gate 9 is set at a high level and no trigger is applied to a d type flip-flop 1. Then the signal 8 is set at a low level in case the evaluation chip receives a privileged interruption request from a control CPU and performs an evaluating job in a program executing state. Therefore, the register contents can be set as conventional by carrying out a writing operation to a mode switching register.

Title: Method of purifying silicon tetrafluoride gas
Inventor: NISHITSUJI TOSHIHIKO
IPC: C01B33/107
Filed: 1988-05-09
Abstract: PURPOSE:To efficiently remove CO2 in silicon tetrafluoride by passing the silicon tetrafluoride gas through an activated alumina layer specifically pre-treated. CONSTITUTION:The silicon tetrafluoride gas at least contg. CO2 is passed at -10--90 deg.C through the activated alumina layer dehydrated in advance by heating at 250-900 deg.C, without substantially contaminating water. When the activated alumina is heated below 250 deg.C, the water in the activated alumina can not be completely removed, even trough heated for a long time period, and the CO2 in the silicon tetrafluoride also can not be sufficiently removed. When the activated alumina dehydrated by heating is cooled, the contamination of water must be avoided as completely as possible. The temp. for passing the silicon tetrafluoride must be <=-10 deg.C, and the lower, the better. However, since the sublimation temp. of silicon tetrafluoride is -95 deg.C, the operation below this temp. is practically difficult.

Title: Heat exchanger
Inventor: IMAI SEISHI

Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To provide a heat exchanger for the outdoor unit of a heat pump type air conditioner in which resistance against frosting is enhanced by retarding clogging of a wind path due to frosting. SOLUTION: Planar fins 12 are arranged such that two arbitrary planar fins 12 adjacent in the axial direction of a heating tube 11 are raised alternately in the opposite directions. Even after an air channel having a raised piece between the bases of the planar fin 12 is clogged, air flows through an air channel having no raised piece between the bases of the planar tin 12. Consequently, heat is exchanged between the air and the refrigerant and heat exchanging capacity can be sustained.
