Title: Powder beam processing device and powder beam processing method
Inventor: KURODA MASAYUKI
IPC: B24C5/04
Filed: 1992-04-15
Abstract: PURPOSE:To prevent adhesion of powder to each other by vibrating injected powder beams. CONSTITUTION:High pressure fluid is injected against a solid gas two-phase mixture flow conveying pipe 2 through a fluid feed pipe 5 and powder is fed through a particulate feed pipe 7 to the solid gas two-phase mixture flow conveying pipe 2. High pressure fluid and powder are mixed together in the solid gas two-phase mixture flow conveying pipe 2 to produce a solid gas two- phase mixture flow, which is conveyed to a first nozzle 9 and accelerated by the first nozzle 9 and delivered as an acceleration flow to a second nozzle 13. The acceleration flow forms a parallel flow by means of the nozzle part 14a of the second nozzle and through excitation of the exciting part 16 of the second nozzle 13, powder passing through the nozzle part 14a is excited and injected as powder beams to a work. Thus, the powder beams are uniformized without being coagulated and adhered to each other and microprocessing of the work is practicable.

Abstract: PURPOSE:To enable the issue of a game to be instantly decided by deciding the issue of the piece game fixedly with an electronic type issue-deciding-machine, and by competing with each other for the occupation of a position. CONSTITUTION:A game playing order is determined by two players, and each player has 20 pieces S, 20 pieces T, and 10 pieces A. As a same board, a checkerboard-like one is used, and with a central line 8 for a boundary, the pieces of each player are to be put one by one alternately within each position. In this case, in place of putting the pieces, each only one ready-put piece of each player may be moved, but they cannot move each piece of them to the positions of each rival player. When the arrangement of the pieces is completed to some extent, then playing the game is declared, and the pieces of the players can be moved within the positions of their mutual rival players. When the pieces of the players and the pieces of their mutual rival players are put together, then the issue of the game is discriminated by an electronic type issue-discriminating machine, and the pieces of the player who lost the game are removed from the board. When the players can put their pieces S at their mutual rival positions, then the rival positions can be set as the players' positions, and at the rival positions, the marks of the players, positions are put. At the positions, the players can put their own captured pieces, but the rival players cannot put them there.

Title: Chemical emission-type gas analyzer
Inventor: KOZAKURA MASARU
IPC: G01N21/76
Filed: 1993-05-24
Abstract: PURPOSE:To obtain a chemical emission-type gas analyzer which restrains ions to be generated from flowing into a luminous reaction cell and which eliminates an extinction phenomenon by a method wherein a device which removes the ions is installed in the halfway part of an ozone-gas flow passage between an ozone generator and the luminous reaction cell. CONSTITUTION:Two pairs of electrodes 9, 9' and 10, 10' are arranged so as to protrude inside an ozone-gas flow passage between an ozone generator and a luminous reaction cell, and a high-frequency high voltage is applied across the individual electrodes. At this time, the electrodes are arranged in such a way that the direction of an electric force to be formed, i.e., an electric repulsive force, crosses the flow direction of a fluid. As a result, ions are preserved in a space. (When the high-frequency high voltage is applied across two electrodes, an arc-shaped line of electric force is formed in a space between the electrodes. When the ions enter the space, they vibrate the line of electric force, an electric repulsive force is received in its tangential direction, and the ions are preserved in the space). Then, it is possible to restrain the ions generated by the ozone generator from flowing to the downstream side of the flow passage, i.e., to the emission reaction cell.
