Title: Multilayer wiring structure and its manufacture
Inventor: MIURA OSAMU
IPC: H01L23/538
Filed: 1993-03-11
Abstract: PURPOSE:To make it possible to form a fine wiring layer by providing complex having more than two sets of subassemblies having a construction of formed wiring layers in such a manner that the area ratio will correspond through an insulation layer on both the surfaces of a core material made of a low thermal expansion metal and by reducing dimensional changes of substrate. CONSTITUTION:For the wiring sheet, copper wires 3 are formed on both the surfaces of a polyimide film 2 for which the thermal expansion coefficient was matched to copper. This wiring sheet is laminated on a mullite substrate by an adhesive film 4 and a multilayer laminated board 6 made of wiring sheets is produced. In this case, a core member with the thermal expansion coefficient of 1X10<-5>/ deg.C to 1X10<-7>/ deg.C is provided, for example, an invar foil is inserted to copper-lined polyimide sheets for realizing low heat expansion. By doing this, mismatch of thermal expansion coefficient between copper-lined polyimide sheet and mullite substrate can be reduced.

Title: Heat exchanger
Inventor: OKAMURA AKINOBU
IPC: F28F9/26
Filed: 1992-03-09
Abstract: PURPOSE:To improve operability at the time of assembling by reducing a diameter of a pipe of a lower side with resect to gravity of a distributor. CONSTITUTION:A distribution pipe 3 of a U-bent shaped is made to hydraulically protrude at its inlet 3a, drawn at its lower pipe part 3d, and further enlarged at its lower pipe part 3e. In this case, a length l1 of an inner wall is increased 2<1/2> times of 1/2 of a difference between an inner diameter d) of a thick part and an inner diameter d2 of a thin part, and a length l2 of a thin part is so drawn at the thin part as to be longer than the diameter d2 of the thin part. Thus, refrigerant can be uniformly distributed, and further a refrigerant distributing amount can be easily regulated. Since an abrupt pressure loss is eliminated, no refrigerant sound is generated, and operability at the time of assembling can be improved.

Inventor: TATEYAMA SATORU
IPC: C21D1/82
Filed: 1989-03-02
Abstract: PURPOSE:To peel primary scales adhering to the surface of an austenitic stainless steel slab and to easily remove the scales from the surface by applying water cooling to the above steel slab when its surface is at a specific temp. CONSTITUTION:When the surface temp. of an austenitic stainless steel slab 1 after slabbing is 100-800 deg.C, this slab 1 is dipped into a cooling water tank 2 to undergo water cooling.

Filed: 1985-03-13
Abstract: PURPOSE:To simplify the structure of a pick and place unit by combining function for stopping rotation with sliding function by means of a rectangular slide shaft and a guide piece in the pick and place unit to feed work. CONSTITUTION:A lever 6 and block 7 interlock with a driving cam fixed to a main body 4, and a slide shaft 8 being of a rectangular section is therefore held between plural guide pieces 9 whose a pair of square portions are fixed to a slide block 10, and is moved back and forth through the tension of a spring 12. A lever 6A interlocks with a block 11, and the slide block 10 is therefore guided by guide pieces 9A between both the slide shafts 8 under the tension of the spring 12. Thus the directions of sliding and rotation of the slide shaft 8 can be similarly controlled in moving back and forth or vertically. Consequently the slide section can be simplified, and moreover the number of parts and their weight can be reduced, and the whole space occupied by the unit also becomes less.

Abstract: PURPOSE:To allow the content of conversation to be listened by concerned persons only by synthesizing a voice at a frequency band other than the voice effecting the understanding of the content of conversation with a masking voice and reproducing the synthesized voice through a nondirectional speaker. CONSTITUTION:The frequency band is split (split into A and B) at a frequency split circuit 11 to an audio signal of a monaural sound X(=A+B) transferred from an input terminal 10. For example, the voice A of a noticed characteristic frequency region is reproduced by a directivity speaker 12 and the voice B of the other frequency is transferred to a making sound addition section 25. The masking sound addition section 25 adds the 'masking sound C with respect to A' to the voice B and the synthesized sound (B+C) is reproduced by the nondirectional speaker 13. Thus, the directivity speaker 12 acts it that the content of conversation is not listened to a person not concerned resident therearound (not understood) but listened to a person concerned 15.
