Title: Vapor phase synthesis device
Inventor: KIKUCHI MOTOHARU
IPC: C30B29/40
Filed: 1988-01-20
Abstract: PURPOSE:To directly grow a crystal body suitable for cutting out a stock for a condenser lens for large output, etc., by disposing a raw material supply nozzle in a specific form and synthesizing a circular columnar crystal body in a vapor phase. CONSTITUTION:The circular columnar crystal body, for example, ZnSe crystal body, is prepared in the following manner: A hollow cylindrical base body which is closed at one end and has a round bar at the center is supported at the center of a reaction chamber by a revolving shaft. Nozzles for supplying gaseous H2Se and a Zn vapor-contg. carrier gas are oppositely disposed to the open end of this base body and if necessary, a flat plate base body is placed around this base body and is heated by a heater provided on the outside of the reaction chamber to the crystal growth temp. Since the inside of the hollow cylindrical base body is blown directly with the gaseous raw materials from the supply nozzles, the crystal growth speed is extremely higher than the crystal growth speed of the outside. The vapor growth is ended in the stage when the crystals deposit successively in this base body and the inside of the base body is completely filled therewith. The deposition of the crystals is uniformized by rotating the base body.

Title: Taping apparatus
Inventor: HIRAI HIROYUKI
IPC: B65B15/04
Filed: 1992-01-22
Abstract: PURPOSE:To maintain satisfactory state of taping even after winding-up by a take-up reel by specifying the curvature for the round part of a lower guide for an apparatus with which a parts supply tape made up by providing parts- holding parts over a base tape and by sticking a top tape to the surface of the parts-holding parts is wound up by the take-up reel. CONSTITUTION:A parts supply tape 11 made up by providing protuberant parts- holding parts 13 on a base tape 12 is supplied from a supply reel and is guided between an upper guide 3 and a lower guide 4, and a top tape 21a supplied from a supply reel 21 is stuck over the parts supply tape while both of the tapes are caught between the lower guide 4 and a pressing roller 5. After that, the tapes stuck together are made to pass under an upper guide 6 and are wound up by a take-up reel. The radius of curvature on the round part R of the lower guide 4 is made smaller than the radius of the inner diameter of the take-up reel. As a result, excessive tension is applied neither to the top tape 21a nor the base tape 12 even after the parts supply tape 11 is wound up by the take-up reel, and thereby satisfactory state of taping can be maintained.

Title: Forming method for minute pattern
Inventor: NISHIDA HIDEKI
IPC: H01L21/027
Filed: 1982-01-25
Abstract: PURPOSE:To eliminate the faulty adhesiveness of a photomask by coating the surface of a photoresist film with very thin resin which is light-transmitting and non-photosensitive. CONSTITUTION:After an Al film 2 to be formed into a conductor pattern is formed on a silicon wafer 1 by evaporation, a positive-type photoresist film 3 is formed thereon, and further a water-soluble polyvinyl alcohol resin film 4 is formed thereon with the thickness varied in the range of 50-1,000Angstrom , a light- transmitting and non-photosensitive resin. Successively, a minute photomask pattern is formed on said resin 4. In a method of forming such a minute pattern, a time at which a photomask 5 and the wafer 1 start to separate from each other during exposure was examined with the thickness of the resin film 4 varied. As the result, it was found that the exposure could be performed in the state that the photomask 5 adhered completely to the polyvinyl alcohol resin film 4 by connecting the film 4 with the thickness of 100Angstrom  or more to the film 3, and that it was very preferable for the film to be about 100-200 deg.C thick in view of an optimum time of exposure and a time for a preparatory process.

Abstract: PURPOSE:To improve the durability of the joint part of Al members by forming the basic compsn. of a flux of respectively specific weight % of potassium hydrogenfluoride and zinc fluoride and further, adding lithium fluoride thereto at prescribed % of the entire part. CONSTITUTION:A mixture composed, by weight, of 30-50% potassium hydrogenfluoride and 70-50% zinc fluoride is formed as the basic compsn. of the flux. The flux is constituted by using such mixture at 99-95% of the entire part and 1-5% lithium fluoride as an additive. No residues remain in the joined material after brazing if the Al materials are joined by brazing using such flux. Since the corrosion of the joint part arising from the residues is thereby prevented, the corrosion resistance of the joint part of the Al members is improved.

IPC: C23C14/32
Filed: 1987-01-20
Abstract: PURPOSE:To obtain the titled device capable of stably forming a thin Al film by constituting the device so that electrically-conductive BN is used as the material of a crucible and Mo is used as the material of a grid and a grid electrode respectively and also the lower end part of the grid is freely moved to the lattice direction of the grid. CONSTITUTION:Al being a material 4 to be deposited by evaporation is jetted through the nozzle 3 of a crucible 2A and the clusters 7 of Al are formed by adiabatic expansion. At this time, the clusters 7 can be stably fed because BN constituting the crucible 2A is excellent in corrosion resistance for Al. Thermions discharged from a filament 9 are drawn out to the inside of a grid 10A and the clusters 7 are ionized to form cluster ions 14. In this case, since the supporting plate 23 is a grid lattice is freely moved to the lattice direction of the grid 10A, breakage of the grid 10A resulting from thermal fatigue is prevented by escaping thermal stress. Simultaneously since Mo constituting the grid 10A is excellent is corrosion resistance for Al, the service life of the grid 10A or the like is prolonged. Then the ions 14 are reached to a base plate 16 and a required vapor-deposited thin Al film 17 is formed on the surface of the base plate 16.

Abstract: PURPOSE:To reduce toner consumption by reducing surface charges on the photosensitive surface by a light source provided between an electrifier and an optical writing head before a photosensitive body starts rotating or after it stops rotating when an image is formed by a reversal development system and impressing a voltage on a developing part first when rotation starts. CONSTITUTION:A light emitting element 16 exposes an area from a position where the photosensitive surface 2 faces the electrifier 3 to a position where it faces the developing part 5, and surface charges are reduced before the photosensitive body 1 starts rotating. Then, when it starts rotating or slightly before that, voltages from high voltage power sources 12 and 14 are impressed on the electrifier 3 and a transfer unit 6, and a developing voltage is impressed on the developing part 3, until a surface charge reducing part faces the developing part 5 and passes by it together with the rotation of the photosensitive body 1. In such a way, a normal recording action is carried out after rotation stats, and at the end of the action, the photosensitive body 1 stops rotating, or afterwards the voltages for electrification and transfer from the power sources 12 and 14 are lowered to non-electrification level, and the operation is ready for next storing action.
