IPC: B23K3/02
Filed: 1987-10-21
Abstract: PURPOSE:To continuously operate an IC device for automatic soldering for a long period by coating the contact part with a solder by a ceramics material and coating the vicinity of a heater chip fitting par by the metal or alloy of oxidation resistance and heat resistance. CONSTITUTION:The contact face of a heater chip with a solder means a heating face (a) and its circumferential part (b). A molybdenum (Mo) is used for the base metal of the heater chip. The ceramic material coating its contact part with a solder may be good provided it has a bad wettability with a solder and good thermal conductivity and there are TiN, AlN, etc., for the same. The higher electric resistance is preferrable and there are SiC, SiN, etc. The coating of the ceramic material is by a CVD method (vapor phase plating method), etc. Those which are oxidation resistant and heat resistant are good for the metal coating the vicinity of a heat chip fitting part and they are Ni, Au, Pt, etc., and connected to the heater chip power source part main body by a fitting hole C. The need for executing a grinding work and oxide film removing work frequently is thus eliminated hence the productivity can be improved by performing the continuous operation of an automatic IC soldering device.

Title: Control system of water supply pressure
Inventor: SUZUKI MASAYOSHI
IPC: G05D16/00
Filed: 1984-12-14
Abstract: PURPOSE:To prevent the mutual interference with a control system of water supply pressure by controlling a water pressure control valve with a prescribed pattern based on the deviation of the water supply pressure of each water supply control terminal and the variance of the water flow rate. CONSTITUTION:This control system contains the water supply control terminals in the course of a pipeline for supply of water to each house from a distributing reservoir. The water pressure P2 of each terminal is kept at a prescribed level, and each terminal compares the real water pressure P2 measured by a pressure gauge 103 with the target water pressure P02 indicated through a telemeter 105 to obtain a deviation DELTAP. This deviation is supplied to a valve drive part 204 via a blind sector setting unit 201, a valve characteristics correcting part 202 and a control amount deciding part 203 for control of the opening amount of a valve 102. Then a pipeline flow rate meter 1104 is provided together with a detecting part 1101 for flow rate variance DELTAQ/DELTAT, a control pattern deciding part 1102 and a gain setting part 1103. Thus it is possible to decide whether the correction and control should be carried out at an own area or not from the combination of the amount and the direction of variance of the water supply pressure of the own area and the combination of the amount and the direction of the flow rate variance of water.

Filed: 1989-10-11
Abstract: PURPOSE:To effectively utilize a space in a room and to prevent external appearance of an installed location by covering the surface of a piezoelectric speaker with the same coating member as that of a wall face and embedding the piezoelectric speaker in a mount location recessed onto the wall face. CONSTITUTION:The structure is adopted such that plural number of piezoelectric drivers 3 are embedded in the inside of a rectangular diaphragm 2 whose lateral size is longer than the longitudinal size. The peripheral part of the diaphragm 2 is supported by a frame 4 like a picture frame and the front face of a piezoelectric speaker 1 including the frame 4 is entirely covered with covering member 10. The same member covering the wall face to which the piezoelectric speaker 1 is mounted as wallpaper is used for the coating member 10. Since the piezoelectric speaker 1 is embedded in a mount part 6 and its surface is covered by the same member 10 as that on the wall face 20, the speaker 1 is integrated with the wall face 20. Thus, the space saving is realized and the external appearance of the install location is not lost.
