Title: Microfabrication device
Inventor: HOSOI NOBUKI
IPC: H01L21/3065
Filed: 1997-08-18
Abstract: PROBLEM TO BE SOLVED: To suppress inhibition of etching reaction, and to perform microfabrication at a high rate by forming the flow of a gas within a reaction chamber to promote the flow of a reaction product released from the surface of an object to be etched. SOLUTION: In this device, a reaction chamber 1 has an almost rotationally symmetric shape with respect to the central axis 13 and a gas introducing port section 8 is placed in the vicinity of an electrode 2 so that the flow of a reactive gas jetted out from the gas introducing port section 8 has no flow component counter to the flow of a gaseous reaction product, to jet out the reactive gas from the port section 8 toward an object to be etched 9. Also, a counter electrode 3 formed from a metallic net so as to pass the gas including the gaseous reaction product, reactive gas, etc., through the counter electrode 3, is preferably used and gas discharge ports 11 and/or 12 are placed at positions on the extension of flow streams of the gaseous reaction product, etc., respectively, to enable efficient evacuation by a vacuum pump.  Further, a trap is placed within the reaction chamber 1 downstream from the object 9 with respect to the flow of the gas including the reaction product, etc., in order to assist the flow of the reaction product in the reaction chamber 1, wherein the trap is maintained at an appropriate temp. to adsorb only the reaction product and to effectively remove the reaction product released from the surface of the object to be etched 9.

Title: Polishing roll of one-pass rice-polishing machine
Inventor: HOSOKAWA KATSUO
IPC: B02B3/06
Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To prevent grains from being stuck in a polishing chamber and also to reduce broken rice in a polishing roll of an one-pass rice polishing machine in which plural projecting baffles are arranged on the outer peripheral surface of a polishing part by forming pressure vibration grooves extending along the projecting baffles on the outer peripheral surface between the projecting baffles. SOLUTION: Raw material grains G that have fallen into a fall cylinder 11 from a raw material tank 10 are sent to a polishing chamber 14 while pressurized by a grain sending screw of a grain sending part 25 and are moved while polishing pressure is applied to them in a polishing part 21 of a polishing roll A. At this time, the grains G passing through the polishing part 21 are moved while given vibration by pressure vibration grooves 30a, 30b. When the grains G abutted on an outer peripheral surface 21s of the polishing roll A is pressurized by a groove boundary part, they receive a strong pressing force, but when they pass the groove boundary part and are positioned in grooves 30a, they receive a small pressing force.  The grains G thus are pressed by the projecting baffles 21a, 21b while receiving uneven pressure, and after that, they fall to a polished rice discharge port 41 from an outlet 39 and are housed in a polished rice vessel.

Title: Three-phase phase separation bus line
Inventor: HIGUCHI TAKAHARU
IPC: H02B13/02
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To restrain a V-phase terminal adapter from having harmful heat and provide easy installation and higher reliability, by setting the thickness of the middle phase of a three-phase isolation plate, which is inserted between the terminal adapter and a three-phase short-circuit plate and isolates both of them, thicker than those of end phases. SOLUTION: The thickness of insulation plate 12b at V-phase of its middle phase is set at about twice as large as those of isolation plates 12a, 12c at Uphase and W-phase of their end phases out of isolation plates 12a, 12b, 12c inserted between a three-phase short-circuit plate 5 and the flange 15 of a terminal adapter 10, and a difference in thickness between them is larger than the thickness of the flange 15. The electric current flowing into the three-phase short-circuit plate 5 from respective phase bus line housing 4 concentrates near the middle of the three-phase short- circuit plate 5, and electric current around V-phase increases.  However, the insulation plate 12b at V-phase is thicker than the insulation plates 12a, 12c at other phases, therefore, a distance between the three-phase short-circuit plate 5 to the flange 15 of the terminal adapter 10 at V-phase increases, and a proximity effect from the electric current of the three-phase short-circuit plate 5 decreases. It is thus possible to restrain heat generation around the flange 15 at V-phase.
