Title: Heat dissipating struture of semiconductor element
Inventor: MORITA TETSUO
IPC: H01L23/34
Filed: 1984-06-18
Abstract: PURPOSE:To enable marked reduction in the substantial thermal resistivity of lead terminals by a method wherein the lead terminals are made integral with a connector. CONSTITUTION:The upper end of a lead terminal 2 is in contact with a circuit board 3 positioned at the upper part in the casing 1, and necessary semiconductor elements 4 are mounted on the circuit board 3. The lead terminals 2, circuit board 3, and semiconductor elements 4 are fixed with a potting resin that forms the casing 1. Then, the connector 6 of the lead terminals 2 is arranged e.g. from the circuit board 3 in the casing 1 to the neighborhood of the lower surface of the casing 1, and is joined to the lead terminals 2 by brazing or the like. Since the lead terminals 2 are made integral with the connector 6 in such a manner, substantial reduction in thermal resistivity of the lead terminals is enabled.

Title: Manufacture of semiconductor device
Inventor: SHIMODA HIROSHI
IPC: H01L21/56
Filed: 1988-05-19
Abstract: PURPOSE:To enhance shot effect, eliminate generation of dust and make processing of waste materials unnecessitated by using ice as a shot material and eliminating burrs by spraying mixture of ice and water to burrs. CONSTITUTION:Burrs 3 can be eliminated by utilizing the ice grinding effect by spraying, from a nozzle, the ice made by an ice maker 5 and compressed water from a high pressure pump 4 as the ice shot material 7 mixing the water and ice. The ice shot material 7 is collected by a collector 8 after elimination of burrs and is then returned to the ice maker 5. Thereby, the shot material can eliminate burrs not swelled by electrolysis or thick burrs by the grinding effect. Moreover, since ice is used as the shot material, the burrs may be collected, dust is not generated and non-public hazard burr elimination, which does not require the processing of waste material can be realized.

Title: Solder material
Inventor: TAKEDA NAOKO
IPC: H05K3/34
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To inexpensively provide a nonleaded material having excellent workability and high wiring reliability by composing it of specified weight% of Bi, Ag, Cu, In, and substantially the balance Sn. SOLUTION: When Cu and In are added to a Sn-Bi-Ag solder material, the characteristic of solder is improved while restraining the quantity of Bi making solder brittle by adding a large quantity of it and expensive Ag so as to reduce. That is, this solder material is composed of a Sn-Bi-Ag-Cu-In alloy. The compositional ratio of Sn, Bi, Ag, Cu, In is, by weight 1.0-12.0% Bi, 0.5-6.0% Ag, 0.1-3.0% Cu, 0.5-10.0% In and substantially the balance Sn. Since the melting temperature in the solder material of composition like this is about the same as that of Sn-Pb solder, the present soldering process of Sn-Pb solder is used as it is. By this way, the melting temperature is optimized, and the wettability and mechanical characteristic of solder liquid are improved.

Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To stably maintain contact between a negative electrode metal and an electrolyte and connection with a current collecting body even if impact or vibration are applied, and stably take out an electric current by molding a mixture of Zn power, Zn alloy powder and a desolvated substance into a cylindrical body, and sintering it after pores are formed by desolvating the substance to be desolvated. SOLUTION: A mixture obtained by mixing Zn powder of raw material powder for a negative electrode, Zn alloy powder and mixed powder P of Zn powder and the other metallic powder and a desolvated substance D, is fed to hopper 71. A pushing- out plate 74 is advanced to a discharge port 73 side by a driving device, and is moved to a reduced part 72 while compressing the mixture. The mixture is taken out of a taking-out port 73 as a round bar-shaped mold 76. The mold 76 is heated to 200 to 400 deg.C in a nonoxidizing atmosphere in a desolvating furnace, and the desolvated substance D is baked away. Next, it is heated to about 350 to 400 deg.C in a reducing atmosphere in a sintering furnace, and the raw material powder P for a negative electrode is sintered. Thereby, negative electrode metal having comparatively large diameter pores three-dimensionally can be obtained.

IPC: C07C67/00
Filed: 1979-09-27
Abstract: PURPOSE: To prepare the titled compound useful as a raw material of a polycarbonate esin, etc., in high conversion and yield, by reacting phenol and acetone using cysteine and a water-insoluble solfonic acid-type cation exchange resin as catalysts.  
     CONSTITUTION: Bisphenol A is prepared by condensing phenol and acetone in an inert solvent or in the absence of solvent, in the presence of a catalyst comprising a modified resin obtained by modifying pref. a cation exchange resin with cysteine, under a pressure of 1W5kg/cm 2 G at 50W100°C for 0.1W20hr. Since the presence of water in the reaction system gives undesirable effects to the reaction, the concentration of water in the reaction system is preferably maintained below 0.1wt%. The degree of modification of the cation exchange resin with cysteine is 5W20mol% based on the sulfonic acid group. If cysteine is added to the reaction system separately, its amount is 0.01W0.5wt% based on the sum of the phenol and acetone used as raw materials.

Title: Ac-dc converter
Inventor: YAMADA NAOHIRA
IPC: H02M7/155
Filed: 1978-10-11
Abstract: PURPOSE: To suppress short-circuit currents by giving high impedance to a reactor with an intermediate tap against the short-circuit currents, in the case transformers having three-phase winding for converters are provided to cancel (6K±1) the harmonic.  
     CONSTITUTION: When the thyristor arm of either of thyristors 6A or 6B is short- circuited, a short-circuit current is flown through each transformer. The short-circuit current from the transformer on the good side flows from one end of a reactor 12 having an intermediate tap to the other end thereof. The reactor 12 having the intermediate tap develops high impedans against said current, thereby the short- circuit current can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To maximize yield when both are made a set even when distributions are provided in plating thickness, composition and magnetic characteristics, etc., by adopting a method alternately arranging many UP heads and DN heads on a wafer and manufacturing it. SOLUTION: The DN head 2 is a thin film magnetic head reading/writing the data on a magnetic medium from the upper side of this magnetic medium. Further, the UP head 3 is the thin film magnetic head reading/writing the data on this magnetic medium from the lower side of the magnetic medium. Then, by alternately arranging the DN heads 2 and the UP heads 3, even when e.g. a current distribution when electroplating is performed is biased, since the DN heads are arranged close to the UP heads, both characteristics become nearly equal, and the yield when a pair of both are selected to be finished up as a product is improved. The DN head 2 and the UP head 3 are combined back to back, and a pair of them is applied with a magnetic field on the wafer 1, and a magnetic film is formed to be manufactured.
