Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that a uniformity when a semiconductor substrate is processed, for example, a uniformity of a thin-film forming rate or a thin-film etching rate in the plane of the semiconductor substrate is required to be accurately controlled in a process of manufacturing a semiconductor device, and this necessity is more strictly demanded as the diameter of the substrate is made larger.  <P>SOLUTION: Since a cathode electrode 25 having the semiconductor substrate mounted thereon is covered with a mesh-net-like anode electrode 27, a plasma 30 generated between the electrodes can be trapped in a space between the electrodes and a large quantity of processing gas can be made to flow. For this reason, the semiconductor substrate 26 can be uniformly processing in its plane.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Filed: 2004-02-17
Abstract: <P>PROBLEM TO BE SOLVED: To realize a shut-off valve capable of reducing a load of a driving means because a pressure difference capable of opening the valve for reset is high, restricted in the generation of abrasion and lock in the driving means, and restricted in probability that a fluid seal part of a valve seat is permanently deformed.  <P>SOLUTION: An engaging means 36 pulls a winding part 33b, and the periphery of the valve seat 33 near a valve seat abutting part 33a is partially bent for deformation to form a small opening part 55 between the valve seat 32 and the valve seat 33, and a pressure difference can be thereby reduced with a weak load. Since the engaging means 36 are evenly arranged in rotary symmetrical positions, oblique loads when solving a pressure difference are offset each other. Since an oblique load is not given to a stepping motor 35 to restrict probability that abrasion and lock is generated and a bending and deforming position of the valve seat 33 is displaced in a rotating direction to avoid fixation during the repeating operation, the shut-off valve restricted in the generation of permanent deformation of the valve seat abutting part 33a of the valve seat 33 can be realized.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide a game machine capable of suppressing the remarkable excitation of a gambling spirit by suppressing the generation of continuous advance announcements.  <P>SOLUTION: Whether or not a winning flag is 0 is judged in S240. The initial value of the winning flag is 0 and it becomes 1 in the case that there is a winning in holding. At the time of being 0 (S240:YES), the processing advances to S241, and whether or not a random number value read in S230 is a big winning is decided. The processing shifts to S242 in the case of the winning (S241:YES), the winning flag is set (turned to 1), the continuous advance announcement instruction signal of the winning is set in S243 and the processing shifts to S247. In the case of deciding that the winning flag is not 0 in S240, the processing directly advances to S247. In such a manner, in the case that the winning flag is 1, that is there is the random number of the big winning in the holding, the continuous advance announcement instruction signal is not newly generated. Thus, the generation of the continuous advance announcements can be suppressed.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
