Title: Reducing-sintering method for high speed steel powder
Inventor: OONO EIJI
IPC: C22C33/02
Filed: 1978-06-23
Abstract: PURPOSE: To reduce the oxide in the surface layers of high speed steel particles simultaneoulsy with sintering, by coating the high speed steel particles produced by water-spray method with phenol resin, and after the steel particles are shaped into green compact, by inserting the compact into a reducing furnace heated by a heater in an atmosphere of nitrogen.  
     CONSTITUTION: High speed steel powder manufactured by water-spray method is coated with novolak type phenol resin to form resin-coated powder, which is shaped by compression and heated at a reducing temp. 1,000W1,300°C in a nitrogen gas stream for 0.5W2 hrs. so as to be sintered. After completion of reducing-sintering, the amount of residual carbon can be controlled to a desired quantity freely in proportion to the coated amount of the phenol resin, the time and the temp. for the reduction. Hereby, nitrogen content of the sintered compact is increased and the performance after hot forging is improved, so that fineness of the crystal grains and the hardness after tempering are increased.

Title: Voice coil for speaker
Inventor: KOKUBU NORIO
IPC: H04R9/04
Filed: 1989-03-28
Abstract: PURPOSE:To prevent a foaming phenomenon to be generated between insulated lead wires in the case of heating and setting by applying the thermal setting adhesive agent of high concentration to a part to be wound such as a voice coil bobbin, etc., and winding the insulating lead wire on the part to be wound while the thermal setting adhesive agent of the low concentration is applied. CONSTITUTION:In comparison with a thermal setting adhesive agent layer 2a formed in a part where goes to be the part to be wound of a voice coil bobbin 1, and is composed of triazine resin, for example, the concentration of an adhesive agent 5 is especially low. While the adhesive agent 5 is applied, an insulated lead wire 3 is wound on the adhesive agent layer 2a. Afterwards, a whole body is heated and set. Thus, in the case of the heating and setting, the generation of foam in the adhesive agent between the adjacent insulated lead wires or the floating phenomenon of each insulated lead wire caused by the reduction of the adhesive agent in the part can be eliminated.

Title: Storage of blood
Inventor: KITA SHOICHI
IPC: A61K35/14
Filed: 1986-04-02
Abstract: PURPOSE:To slow down the degradation of stored blood and to enable long-term storage of blood, by adding adenine to stored blood or concentrated erythrocyte to decrease the freezing point and maintaining the blood, etc., at a temperature lower than 0 deg.C and higher than the depressed freezing point. CONSTITUTION:Stored blood of concentrated erythrocyte is added with a small amount of an additive such as adenine to depress the freezing point of the blood, etc., from -1--2 deg.C to about -5 deg.C and is stored by cooling at a temperature lower than 0 deg.C and higher than the depressed freezing point (i.e. -1--4 deg.C). An erythrocyte preparation for blood transfusion can be stored by this process. Since the temperature gap between 0 deg.C and the freezing point of the blood preparation is expanded by the above method, the blood preparation can be stored at 0 deg.C preventing the freezing of the preparation with each control and the storage period can be prolonged.

Abstract: PURPOSE:To realize a high-density mounting operation and a good heat- dissipating function by a method wherein the tip of a thin outer lead is bent in such a way that its rear surface becomes the same face as the rear surface of a sealing resin. CONSTITUTION:When a resin-sealed semiconductor device is mounted on, and attached to, a circuit board, the rear surface of every tip part of individual outer lead terminal 15, 17, 18 is connected, by means of solder, to a copper foil on the circuit board for mounting. Thereby, the rear surface of a resin- sealed region 23 adheres closely to the circuit board, heat generated at the inside of a transistor 19 is dissipated via an element mounting part 14, a sealing resin and the circuit board. In addition, the outer lead terminal 15 for a collector and the outer lead terminals 17, 18 other than it are arranged so as to divided into both sides of the element mounting part 14. As a result, in a state that every tip of the individual outer lead terminals 15, 17, 18 is connected to the circuit board, the whole region on the rear surface of the sealing resin adheres closely to the surface of the circuit board. As a result, it is possible to obtain a heat-dissipating effect which is not inferior to that by fixing with screws.
