Title: Brazing method and plate type heat exchanger brazed by the same
Inventor: KAWAI MITSUO
IPC: B23K1/008
Filed: 2000-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a brazing method for fixing surely a powder-shaped nickel brazing filler metal on the surface of a joint by using water-soluble binder and a plate type heat exchanger brazed by the method. SOLUTION: The water-soluble binder and the powder-shaped nickel brazing filler metal whose main component is nickel, are simultaneously applied to the surface of the joint of parts to be brazed. After that, after the parts are subjected to a heat treatment of 70 deg.C or over, they are placed in a vacuum furnace, and are brazed and subjected to a heat treatment. Since the adhesive strength of the binder is improved by the heat treatment, the powder-shaped brazing filler metal can be surely fixed on the surface of the joint. Also, before placing the parts to be brazed in the vacuum furnace, they are heated to evaporate moisture from them. Therefore the adverse effect to the vacuum furnace and oxidization of the brazed parts are prevented.

Title: Semiconductor device and liquid crystal module using the same
Inventor: NAITO KATSUYUKI
IPC: H01L25/065
Filed: 2000-04-07
Abstract: PROBLEM TO BE SOLVED: To mount a plurality of semiconductor chips 14, 15 in a smaller area on one tape, in a semiconductor device wherein semiconductor chips are mounted on a tape such as TCP and COF. SOLUTION: The semiconductor chips 14, 15 has a long and narrow shape and are mounted so that the long sides may be nearly vertical to the direction in which Cu wiring patterns 12 may be extracted. Many of the Cu wiring patterns 12 can therefore be arranged nearly in parallel with each other, and so they can go straight ahead to a device to which a signal of the module is outputted or from which a signal is inputted. Since the semiconductor chips 14, 15 are long and narrow, the tape 13 can be reduced in width and thereby a connected equipment can be reduced in size. The wiring length causes only a small influence on speed or the like, resulting in the increase in operation speed.
