Abstract: PURPOSE:To enhance operational function by integrally providing a powder supply vessel to the body of a gun for injecting powder which is suitably used for powder slush molding and constituting the gun for injecting powder so as to surely perform fluidization of powder in the vessel. CONSTITUTION:In the case of powder slush molding wherein powder consisting of plastic is injected on the cavity face of a heated mold, when a trigger 17 is pulled to open a stop valve 11, compressed air flow directed to an injection port 4 is formed through an introduction port 6, an introduction chamber (b), the respective nozzles 24 and a straightening vane 25. A suction chamber (a) becomes a state of negative pressure by the compressed air flow and a normally closing valve 38 is opened. Since the normally closing valve 38 is so provided that the valve port 41 thereof is displaced at an outside air suction port 32 side higher than the surface (s) of a powder layer L in a storage chamber (d), outside air flows through an outside air flow chamber (c) from the outside air suction port 32.

Title: Ink jet recording method, recording head, recording apparatus and data processing mechanism
Inventor: SHIOTANI MAKOTO
IPC: B41J2/01
Filed: 1995-05-12
Abstract: PURPOSE: To record a sharp image while reducing the substitution of ink by preparatory emission or suction/pressurization to the utmost by driving a first heater part when image data is recorded on a medium to be recorded to emit recording ink droplets and driving a second heater part when image data is not recorded. CONSTITUTION: When an image is recorded, a first heater part 1 is driven on the basis of the signal from a control part to emit ink to perform recording and the driving of a second heater part 2 is not performed. When recording is not performed, that is, when recording is performed after the definite standby time of a recording head is elapsed, the second heater part 2 is driven at a part other than a material to be recorded to emit the ink at the tip part of a nozzle. The driving timing of the second heater part 2 is set on the way of the closing of a power supply or the like. It is also effective to determine the substitution of ink by preparatory emission or suction/pressurization based on whether a definite time is elapsed after a timer is incorporated.

Title: Semiconductor device and manufacture thereof
Inventor: NAKANO JIRO
IPC: H01L23/13
Filed: 1996-05-09
Abstract: PROBLEM TO BE SOLVED: To prevent metal bumps from cracking because of the linear expansion coefficient difference between an insulation substrate and the mother board, by placing the insulation substrates apart and electrically connecting the mother board having a different linear expansion coefficient from those of the insulation substrates to the substrates through metal bumps. SOLUTION: An insulation substrate 1 is divided into four equal parts at lines passing the cross point of the diagonal lines on the substrate 1 to apparently reduce the solder bump spacing in appearance into one half the conventional one. When a semiconductor chip 3 is mounted on the center of the substrate 1, the thermal expansions of this substrate 1 and the mother board 10 increase from the ends to the centers. This suppresses the stress applied to high m.p. solder bumps 8 at the corners of the substrate. Thus, it is possible to prevent the solder bumps 8 from cracking to break wires due to the temp. change in the atmosphere surrounding the semiconductor device.
