Title: Wire bonding
Inventor: OKAMURA MASAMITSU
IPC: H01L21/60
Filed: 1987-05-27
Abstract: PURPOSE:To prevent the wire bonding strength from lowering and to prevent an erroneous connection of a wire by a method wherein a connected wire-pad connection part and its neighborhood are irradiated and a coordinate value of a wire bonding operation is corrected on the basis of the reflected light. CONSTITUTION:A tip of a wire 7 penetrating a capillary 21 is formed to be a spherical shape; if this spherical part 22 is pushed by a tip face 21a of the capillary 21, it is connected to a wire bonding pad 23 of a semiconductor chip 2. The light is irradiated, from a direction perpendicular to the pad 23, onto a connected wire-pad connection part 7a and the neighborhood of the connection part 7a; a central point of a pressed trace of the capillary on the wire 7 can be found by an amount of the reflected light. A coordinate value of a wire bonding operation is corrected after an amount of discrepancy between this central point and the central point of the pad 23 has been detected. By this setup, it is possible to surely connect the wire to a central position of the wire bonding pad. Accordingly, it is possible to prevent the wire bonding strength from lowering and to prevent erroneous connection of the wire.

Title: Apparatus for separating air by pressure swing adsorption
Inventor: MAIKERU AANESUTO GAARETSUTO
IPC: B01D53/047
Filed: 1989-05-26
Abstract: PURPOSE: To separate air by means of pressure swing adsorption by arranging a first flow restrictor means at the downstream of a pressure regulator and a second flow restrictor means in a bypass conduit. CONSTITUTION: Since pressure in an adsorption bed 14 communicated with a compressor 4 is higher than that in an adsorption bed 12 at the time of starting, nonadsorpted gas of high nitrogen content in the adsorption bed 14 flows to the adsorption bed 12 and a nitrogen product is continuously taken out of a reservoir 32. When pressure at adsorption beds 12, 14 becomes almost equal, a controller 60 closes valves 54, 56 and opens valves 12, 22, 48 to flow compressed air from the compressor 4 to the adsorption bed 12. When pressure reaches the value to open the back pressure regulator 28, the nitrogen product flows to the reservoir 32. The more pressure drop before and behind the first flow restrictor 30, the more amount of impurities in the nitrogen product flowing to the reservoir 32 increases.  Sizes of the flow restrictors 30, 38 are made so that the nitrogen product supplied to the reservoir 32 has a specific purity and rate when the pressure regulator 28 is opened and pressure in the reservoir 32 reaches a prescribed value.

Filed: 1988-06-03
Abstract: PURPOSE:To prevent composition of aluminum alloy edge and to prevent early abrasion or breakdown of edge due to cutting of steel by performing cutting with a cutting tool having mirror finished cutting face under cutting conditions and cutter shape suitable for cutting of steel. CONSTITUTION:A titanium nitride film is chemically deposited onto the surface of a chip 4 and the cutting face 4a including a bevelled section 4b is mirror finished through buffing. Then a large end hole 1d is bored by means of a boring machine provided with a chip 4, through rotation of a spindle 2 i.e. the chip 4, under conditions for cutting steel i.e. the material at the large end lower half section 1c. Since slipperiness of work on the cutting face is improved through mirror finish of the cutting face 4a, the material at the large end upper half section 1b i.e. aluminum alloy does not compose the cutter even under cutting condition for steel i.e. relatively low cutting speed conditions. Furthermore, since low speed cutting is carried out with a cutter shaped chip 4 which is not sharp and provided with a bevelled section 4b suitable for cutting of steel, early abrasion or breakdown of the chip 4 can be prevented.
