Title: Thin copper wire for electronic devices and manufacture thereof
Inventor: TANIGAWA TORU
IPC: H01B1/02
Filed: 1987-06-25
Abstract: PURPOSE:To obtain thin copper wire suited for bonding wire by constituting with pure Cu containing one or more of specific rare-earth elements (RE) and oxygen respectively by specific contents. CONSTITUTION:Pure copper especially of a purity 99.999% or better containing one or more of Ti, Zr, V, Hf, Cr, Ca, Mg, Y and the rare-earth elements (RE) by 0.05-10ppm in all together with 1-30ppm of oxygen is used. The additive elements has no effect if they are less than 0.05ppm and harmful beyond 10ppm on the other hand as ball becomes harder. Oxygen of below 1ppm has no effect and beyond 30ppm voids are formed in the ball as oxygen reacts with hydrogen in the atmosphere when the ball is formed. In this way, thin wire suited for bonding can be obtained.

Filed: 1983-08-30
Abstract: PURPOSE:To level off the running times of respective compressors throughout the year and consequently contrive to lengthen the lives of the compressors by a method wherein a compressor, which runs mainly, is cahnged-over when cooling operation is changed from/to heating operation in a heat-pump type air conditioner, in which a plurality of the compressors are provided. CONSTITUTION:When a change-over switch 15 is changed-over to a cooling side, a relay 16 is excited, resulting in turning its contacts 16a-16d ON in order to run a first compressor 18. Simultaneously, a timer 20 is excited, resulting in turning its contacts 20a and 20b after a few seconds in order to run a second compressor 19. After that, when a thermostat contact 23 opens itself due to the decrease of cooling load, the secnd compressor 19 is brought to a standstill. On the other hand, when the change-over switch 15 is changed-over to a heating side in order to perform heating operation, a relay 17 is excited, resulting in turning its contacts 17a-17d ON in order to run the second compressor 19. Simultaneously, contacts 20a and 20b are turned ON after the elaspse of the set time of a timer 20 in order to run the first compressor 18. The drive of the compressor 18 is controlled by the opening and closing of a thermostat contact 26.

Title: Single shaft combined action unit
Inventor: MIYAZAKI SEISHI
IPC: F16H25/20
Filed: 1992-05-27
Abstract: PURPOSE:To enable a single shaft combined action unit to be miniaturized by simple constitution even though it has large withstand loads and to increase reliability and accuracy. CONSTITUTION:A right-handed 21a and left-handed 21b thread groove are provided on the outer periphery of a shaft 21 and a first nut 22 is engaged with the right-handed thread groove 21a and a second nut 23 is engaged with the left-handed thread groove.

Title: Method for wiring formation in semiconductor device
Inventor: OTSUKI HIROAKI
IPC: H01L21/3205
Filed: 1986-07-09
Abstract: PURPOSE:To realize high-integration and high-density wiring, by performing insulating isolation of a substrate in the direction of its thickness to form wiring. CONSTITUTION:Groove parts 4 having steep inclined wall planes, that is, stepped parts 4a are formed on an insulating substrate 1 whereon wiring is to be performed. A WSi2 5 film functioning as a wiring material is piled on the bottom parts 4b and stepped parts 4a of the grooves 4, and besides on the substrate surface excluding the groove parts, for example, over the whole surface of the substrate 1. Successively, when this sample (the substrate 1 whereon WSi2 film 5 is formed) is then soaked in several % of HF(hydrofluoric acid) solution for several tens of seconds - several minutes and be oxidized at high temperature of about 900-1100 deg.C, e.g., for about 30 minutes, an oxidizing film 6 is formed uniformly on the flat part of the WSi2 film. On the other hand, the oxidizing film 6' is formed inside the WSi2 film on the stepped parts where oxidizing species are easily diffused because these parts are porous. Hence, insulating isolation is performed between the WSi2 film on the parts 1a excluding the grooves and that on the bottom parts 4b of the grooves, respectively on the insulating substrate, so that upper wiring 7 and lower wiring 8 are realized in three-dimensional structure.

CONSTITUTION:A carry-in conveyor 10 is made tiltable to some extent, and a projecting piece 31 projected inclinatorily is shiftable installed in and around its tip part by a pusher. A sheet of paperboard (a) mounted on the carry-in conveyor 10 gets over an incline of the projecting piece 31 and is stacked on a step part of the projecting piece 31 in succession after the conveyor 10 is made into a tilted state and pressed by a base arm 21. Then, the projecting piece 31 is pressed by the pusher, and the paperboard (a) stacked in pile on the step part is transferred to a carry-out conveyor 34 as a lump and taken out. Consequently, since the paperboard is conveyed surely after being separated one by one in a lump, no trouble happens there.
