Inventor: TERAOKA YASUHIRO
IPC: H01L23/28
Filed: 1988-06-01
Abstract: PURPOSE:To reduce the warpage to sealing resin by a method wherein the upper and lower parts of a semiconductor element are covered with the sealing resin and the thermal expansion coefficients of the upper part and the lower part are adjusted. CONSTITUTION:A metal foil 9 is bonded to the rear of a semiconductor element 1 with die-bonder 5. Then the semiconductor element 1 is placed in a mold and sealing resin 8 is cast to seal the semiconductor element 1 by surrounding the whole semiconductor element 1 with the sealing resin 8. If the mold is so designed as to have the thicknesses (t1) and (t2) equal to each other, the semiconductor element 1 can be placed at the center of a the package and, looking outward from the center of the package, the same structure can be provided around the semiconductor element 1, so that expansion and contraction of the sealing resin 8 caused by curing contraction and heat can be cancelled between the upper and lower parts.

Title: Defective contact deciding method for contactor
Inventor: SUWADA MAKOTO
IPC: G01R31/28
Filed: 1989-05-30
Abstract: PURPOSE:To easily discriminate where the cause of abnormality is existed by supplying a constant voltage always to an output terminal from the probe side and enabling the outputting of a peculiar voltage level when the probe contact is defective. CONSTITUTION:When whether an object to be tested (logic) 1 is normal or not is measured by bringing the probe 2 into contact with the output terminal of logic 1, a decision is made in such a manner that the constant voltage is always supplied to the output terminal from the probe 2 side to make capable of outputting the peculiar voltage level at the time when the contact of probe 2 is defective. That is, when the defective contact is generated at a contact point P for the logic 1 and the probe 2, an output impedance is increased to the unnegligible degree in resistance value as compared with the other resistances since a contact resistance caused by the defective contact becomes large. Then, the probe 2 is brought into contact with the output end of logic 1 to continuously supply the constant voltage Vt always to the contact point P through a resistor R3. This resistor R3 is the one for setting the input voltage Vi of an oscilloscope 3 at the time when the contact is defective to a voltage value different from that of the normal time, by the voltage drop.

Title: Chopper control device
Inventor: KATOU AKIRA
IPC: H02P3/14
Filed: 1980-10-02
Abstract: PURPOSE:To suppress voltage of a filter capacitor and make it possible to perform stable regenerative braking operation, by controlling chopper according to the current signal of a DC motor and the signal obtained by passing it through a differentiating circuit during regenerative control of a DC motor to which a resistance with short-circuit means is connected in series. CONSTITUTION:When a contact point 20 which closes at the same time as the short-circuit command of a resistance 9 and opens when a contactor 10 closes at the same time as the short-circuit command of the resistance 9, a current signal 12 is input into a differentiating circuit 21, and it is compared with a control voltage 22, and a throttling command signal 18 is output according to the current signal 12. Because jumping of voltage at a filter capacitor 3 during short-circuit of the resistance 9 becomes function of the motor current, the drop-out of a current detector 11 due to motor current can be prevented by changing the throttle signal 18 according to the value of the motor current. When short-circuiting is finished, the contact point 20 opens and the control quickly returns to its original state.

Title: Stainless steel excellent in surface properties and corrosion resistance
Inventor: YAMAMOTO AKIO
IPC: C22C38/00
Filed: 1982-08-06
Abstract: PURPOSE:To obtain stainless steel excellent in corrosion resistance and generating no gold dust flaw, in stainless steel with a specific composition, by limiting P content. CONSTITUTION:In stainless steel containing 0.12% or less C and 10-25% Cr, the content of P is limited to 0.02% or less. It is recognized that minute spills resulting in gold dust flaw in a cold rolled steel plate manufacturing process of stainless steel is generated because the protruded part of the base material or the edge part of grain boundary falls down to overspread the steel sheet surface. However, in addn. to this phenomenon, a crack is generated in the part of surface grain boundary at the time of cold rolling and the edge part thereof falls down to ovespread the steel surface at the next or succeeding rolling path to form the minute defect flaw which, in turn, results in the gold dust flaw. This crack of the grain boundary is grain boundary breakage generated due to the brittleness directly under a roll at the time of cold rolling, and the brittleness of the grain boundary is related to P concentrated in the grain boundary. Therefore, by reducing the content of P, objective stainless steel is obtained.

Abstract: PURPOSE:To minimize generation and residue of voids, by a method wherein after a decompressed and defoamed synthetic resin is poured into a material to be impregnated under reduced pressure, the pressure is raised back to a normal pressure, and after decompressed again, it is raised back to a normal pressure and this process is repeated at least once. CONSTITUTION:Seven sheets of polyester non-woven cloth H-8010, 10cmX10cm manufactured by Japan Vilene Co., Ltd. are used in a state of piling-up as a material 3 to be impregnated. After the inside of a vacuum tank 1 is decompressed to degass the air contained in the material to be impregnated, an impregnated synthetic resin 4 is agitated and defoamed by a hopper. After the synthetic resin 4 is gradually poured into an impregnating tub 2 from its bottom until the material 3 to be impregnated is completely covered with, the inside of the vacuum pressure tank 1 is raised back to a normal pressure (1 atmospheric pressure). After decompressed by way of the same condition and procedure as mentioned above, it is raised back to a normal pressure. This process is repeated. By this method, the number of inevitably generating void can be minimized.

Abstract: PURPOSE:To avoid the longitudinal stripes with contrast which appear on a screen of a CRT, by inserting a resistor in series with a closed circit of high-voltage coil  distributed capacitance ground high voltage coil and consuming a ringing energy in the circuit. CONSTITUTION:In a high voltage coil of a flyback tranformer 11, positive pulses only are present, and a ringing current flows via the path as shown by arrow.
