Title: Bonding wire for semiconductor device
Inventor: HOSODA NAOYUKI
IPC: H01L23/48
Filed: 1985-06-28
Abstract: PURPOSE:To obtain inexpensive very thin wire, which can be practically used as bonding wire sufficiently, by specifying the amounts of inclusion of S, Se and Te components as inevitable impurities, and specifying mechanical properties of the highly pure very thin copper wire at the same time. CONSTITUTION:The amounts of inclusion of the components of S, Se and Te as inevitable impurities are specified as follows: less than 0.5ppm for S; less than 0.2ppm for Se; and less than 0.2ppm for Te. The total amount of inclusion of the inevitable impurities is made to be less than 5ppm. This highly pure, very thin copper wire has the following properties: 14-22% elongation, rupture strength of 16-26kg/mm<2>; and Vickers hardness of 38-45 under the raw material state. The wire is suitable for bonding wire for semiconductor devices. When the amount of the inclusion of the total inevitable impurities exceeds the above described value, the properties of the highly pure, very thin copper wire are changed into the properties, which are not suitable for the bonding wire. Therefore, the wire cannot be used in practical applications.

Title: Conductive tape
Inventor: KITAGAWA KOJI
IPC: H05K9/00
Filed: 1989-06-02
Abstract: PURPOSE:To get a tape having good workability and mechanical characteristics by adding carbon fiber which makes ultra-fine powder of a refractory metal or its compound grow as a growth starting portion to a binder such as resin, rubber, etc., by a vapor phase reaction through thermal decomposition of hydro carbon. CONSTITUTION:Carbon fiber is produced in a shape of whisker with a microdiameter almost equal to the diameter of ultra-fine powder of a refractory metal or its compound. The refractory metal to be used for a growth starting portion of carbon fiber is a metal which does not vaporize at a temperature of thermal decomposition of hydrocarbon such as Fe, Co, etc., and grows through a vapor phase reaction. This carbon fiber is held by a binder such as synthetic resin, silicon rubber, etc., to be molded in a shape of string or tape. This whisker-like carbon fiber as a binder has good adhesion and dispersibility and is linkedly and dispersedly held in the binder. Thereby, it is possible to get a heating tape 1 having good conductivity and mechanical characteristics.

Title: Valve
Inventor: HANSU KURISUCHIYAN PEETERUSEN
IPC: F16K31/02
Filed: 1991-06-14
Abstract: PURPOSE: To obtain a steady opening motion of a valve by attaching an insert that acts to expand a clearance between a piston and a valve seat in a valve in which a leak fluid flows between the piston and the valve seat when pressurized fluid is supplied to the piston in a normal closed state by a spring. CONSTITUTION: A stepped piston 4 that serves as a valve-closing member is inserted in a housing 2. The piston 4 comprises a cylindrical portion 6 to be fit into a small diameter hole 7 of the housing 2 via a seal ring 8 in a liquid- tight state, and a head portion 9 to be positioned in a large diameter hole 10. A spring 16 enforces the cylindrical portion 6 so as to close a connecting hole 12 provided in a cover 3. The piston 4 is provided with a through-hole 11 communicating with the connecting hole 12 at its central portion. In addition, a ring-shaped insert 19 made of piezo-electric material is disposed in a valve seat surface 18 of the cover 3. By controlling an electric current for the insert 19, a clearance is formed between the valve seat surface 18 and an end face 17 of the piston 4. Thus, it is possible to obtain an open state of the valve 4.

Title: Motive power transmission device
Inventor: KASHIMA MITSUHIRO
IPC: F16C1/12
Filed: 1979-11-05
Abstract: PURPOSE: To efficiently transmit the pulling force of an inner wire to its end without applying the compressive force of an outer tube to the inner wire, by using a spring to apply constant load to the cable of a brake for a motorcycle or the like.  
     CONSTITUTION: When an inner wire 12 is pulled rightward, a cable 8 is pulled rightward together with an outer tube 9 applying compressive force to the inner wire 12. The end of the outer tube 9 is coupled to a spring 10 through a spring carrier 7. Since the spring 10 thrusts the outer tube 9 leftward by initially set load, the outer tube 10 cannot move rightward but is maintained in a position shown by a full line in the drawing. For that reason, only the inner wire 12 is pulled by a lever 3 and the tension of the wire 12 acts directly to a brake regardless of the compressive force of the outer tube 9 to drive the brake to control the motion of a wheel.
