Title: Manufacture of refrigerant shunt device and refrigerant shunt device
Inventor: TAIRA TERUHIKO
IPC: B21D53/06
Filed: 1993-03-08
Abstract: PURPOSE:To reduce a working man-hour and the number of parts by forming plural connecting tubes projecting on a flat plate, rounding the flat plate, joining both its edges and forming a conical shunt part. CONSTITUTION:The flat plate is deep-drawn at a prescribed pitch to form connecting tubes 13. Then, the nearly trapezoidal flat plate is cut along a cutting line 18 so that a line of connecting tubes 13 are arranged in the center of the flat plate. The flat plate 11a is curved nearly conically and the butted parts 15 are welded to make the shunt part 12. End plats 16, 17 are mounted on both end parts of the shunt part 12. An inflow tube 14 is set to a large diameter end part 17 of the shunt part 12 to make a refrigerant shunt device. Since the flat plate is rounded to form the shunt part 12, a semi-circular tapered inserting member is not required. The refrigerant having a two phase state of gas and liquid can be shunted uniformly, the shunt device can be miniaturized, lightened and manufactured at a low cost.

Title: Image display device
Inventor: SANO YOSHIHISA
IPC: H01J1/316
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To prevent irradiation positional displacement on a target surface of electron beams by driving a plurality of elements on a scanning wiring near a spacer that is placed on the same wiring and supports an enclosure in a plurality of timing. SOLUTION: Electrons are emitted by impressing a scan signal and a modulation signal on each cold cathode element 1012 through terminals Dx1-Dxm, Dy1-Dyn out of a container, and each color phosphor is stimulated to emit light by colliding electrons to a fluorescent film 1018 on a metal back 1019. Elements driven by a scan wiring nearest a spacer 1020 are divided into N groups, and are selected and collected by N elements along the scan wiring. The group of N elements are driven one by one in one frame. The maximum value of electrification voltage in the center of the spacer 1020 is lower than that in the case of no division, because electrification charge due to one driving pulse is small. By restraining electrification on the surface of the spacer 1020 from electron emitting elements to an anode, displacement of an orbit is reduced.
