Title: Cleaning method in dry etching device for semiconductor wafer
Inventor: UEDA AKIHIRO
IPC: H01L21/205
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To remove a reaction product by applying high-frequency voltage between an electrode plate and a chamber under the state, in which a semiconductor wafer to be dry-etched is not placed on the electrode plate. SOLUTION: The semiconductor wafer, in which a dielectric film is formed on a surface, is replaced with one, in which the dielectric film is not formed on a surface, in the semiconductor wafers placed on the top face of an electrode plate 2. The inside of a chamber 4 is exhausted by a suction by a vacuum pump, etc., from an exhaust port 6 under the state while the inside of the chamber 4 is supplied with a reaction gas from a gas supply pipe 5. High-frequency voltage by a high-frequency power supply 8 is applied between the electrode plate 2 and a base plate 1 or the chamber 4. Consequently, no reaction product from one side of the semiconductor wafer is generated in the chamber 4.  Accordingly, the reaction product adhering and depositing on the internal surface of the chamber 4 is gasified and exhausted together with the reactive gas, thus cleaning the reaction product adhering and depositing on the internal surface of the chamber 4.

Title: Seat belt buckle
Inventor: RON KURAAKU
IPC: B60R22/12
Filed: 1989-05-11
Abstract: PURPOSE: To practically restrain shaky tendency of a latch plate in a buckle by making the forward edge part of the slanted upper wing part of an ejection part nipped between the top face of the latch plate and the down face of the flat part of a latch part and the latch plate completely latched in the buckle. CONSTITUTION: A compressive power added to a sliding block 46 by a coil spring 54 forms an upward force working to lift both the sliding block 46 and a flat part 44 of a locking part 26, and this force, on the other hand, turns the locking part 26 upward to separate a locking rod 32 from a coupling with a cross rod 34 of a latch plate 24. Once this occurs, the latch plate 24 is, having been worked by a compressed ejection spring 68, ejected from a buckle 10 by an ejection part 58. A forward movement of the ejection part 58, produced by the compressed ejection spring 68, makes a forward edge part 72 of a slanted upper wing part 66 of the ejection part 58 contact with each contacting part 74 in a push button 20, thus making the push button 20 return to its extended position.  Accordingly, the forward movement of the ejection part 58 completely separates the locking rod 32 from the vicinity of the latch plate 24, and thus any possibility of making the coupling of the locking rod 32 and the latch plate 24 being arbitrary separated is eliminated.

Filed: 1994-05-31
Abstract: PURPOSE:To prevent outside air from going into the suction cup section when sucking by providing a suction cup section, an intake hole connected to a specified suction means at the center section of this suction cup section and a projection formed near this intake hole. CONSTITUTION:When air is taken through the intake hole 6 of a suction pad A, a paper sheet 1 is sucked by a suction cup section 7, and the peripheral edge section Y slightly sags down in the arrow direction due to suction force. The projection C is slightly projected more than the peripheral edge section Y of the suction cup section 7, and the head section Ca abuts on the paper sheet 1 which enters the suction cup section 7. This constitution forms a difference in level between the part sucked to the peripheral edge section Y and the part contacting with the face of the head section Ca in the paper sheet 1. Gap sections B and B are formed between the paper sheet 1 and a paper sheet 1a adjacent to this paper sheet 1 from the inside to outside of the area of the suction cup section 7. Therefore, out side air will not goes into the suction cup section 7 through these gaps B and B, as a result, there is no possibility that the suction pad A suck the next paper sheet 1a adjacent to the paper sheet 1.

Title: Metal wire material running and heating apparatus
Inventor: KOJIMA SEIICHI
IPC: H01B13/00
Filed: 1990-05-10
Abstract: PURPOSE:To prevent a loop part of a metal wire from sagging by composing an electrode pulley of a pully for an incoming line and a pully for an outgoing line, supporting the pully for the incoming line freely rotatably by a driving shaft through a bearing, and connecting the pully for the outgoing line with the driving shaft. CONSTITUTION:A incoming part 1' of a metal wire is wound on a pully 22 for an incoming line, wound on an idler pully, and further wound on a pully 21 for taking a wire out to form a loop. The pully 21 for an outgoing line is rotated by a motor M through a driving shaft S and the metal wire is drawn out at a constant speed and sent to a covering and extruding apparatus. Since the pully 22 for taking a wire in is communicated with the pully 21 for taking a wire out through a brush, the loop part forms a closed circuit through the pully 22 for taking a wire in, the pully 21 for taking a wire out, and the brush. Consequently, elongation due to tensile force is avoided and the thinning of the diameter of the wire due to elongation is prevented.

Title: Diode switch
Inventor: MATSUNAGA MAKOTO
IPC: H01P1/15
Filed: 1981-07-29
Abstract: PURPOSE:To obtain a miniaturized diode switch having high isolation properties, by providing an inductive iris between two metallic posts to which the diodes are mounted. CONSTITUTION:An inductive iris 4 is provided between two metallic posts 2 which are set in parallel to the narrower wall of a waveguide 1. With such a double stage post diode switch, the coupling force is reduced for a magnetic field H which encloses the two posts 2 shown by the arrow marks of dotted lines in the figure owing to a metallic plate forming the iris 4.
