Title: Printing hammer drive device
Inventor: WATANABE SUSUMU
IPC: B41J2/235
Filed: 1985-05-20
Abstract: PURPOSE:To effectively cool the heat of a coil to realize a high-speed printing hammer drive device with little heat, by providing holes on a part of a yoke corresponding to a coil. CONSTITUTION:A permanent magnet 1 is held between yokes 2 and 3, and the yoke 2 corresponding to a printing hammer 4 is wound with a coil 5 releasing the printing hammer 4. On the yoke 3, holes 6 are disposed corresponding to the coil 5. Usually, the printing hammer 4 is attracted to the yoke 2 with being deflected by the attraction force of the permanent magnet 1. But, if the flux of the permanent magnet 1 is eliminated by passing an electric current through a coil 5 when necessary, the printing hammer 4 is released from the face of the yoke 2, resulting in the conversion of the strain energy stored therein to a kinetic energy, whereby printing is conducted. At this time, the heat caused by the loss in the coil 5 is directly cooled by a cooling air 10 blown through the holes 6 provided on the yoke 3. On the other hand, the holes 6 disposed on the yoke 3 corresponding to the yoke 2 prevent the flux leakage from the yoke 2 to the yoke 3, enabling a small sectional area of the yoke 2 and a compact permanent magnet 1 in size.

Title: Method of processing blind via hole
Inventor: KOIZUMI SHINICHI
IPC: H05K3/46
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To enable the hole making in a short time by machining the inside, making use of the accumulated heat generated inside, when machining the outside in conformity with the contour of a blind via hole by means of a laser, for a work where plural layers are stacked. SOLUTION: The focus of the laser beam outputted from a laser oscillator is narrowed down, and it is used to scan a layer along the contour of a blind via hole 19 thereby processing a copper layer 16a positioned outside 19a along this contour into a small width. The copper layer 16a at the surface is eliminated and opened in ring form, which exposes a polyimide layer 17a positioned outside 19a along the contour of the blind via hole 19. The surface layer 16a positioned inside 19b remains in circular form, and it is cut off the copper layer 16b section of the whole surface layer with the cut aperture on the circumference side 19a. This effectively accumulates heat generated inside 19b at processing of the outside 19a.  The round copper layer 16a on the inside 19b remaining first is scanned for machining using a laser by means of galvanometers 2 and 3, under condition that the focus is slid in all range of the blind via hole 19. The polyimide layer 17 can be heated to an evaporation temperature in a short time.

Filed: 1982-06-25
Abstract: In an electrolytic reduction cell for the production of molten metal, particularly aluminium, by electrolysis of a less dense salt a monolayer of ceramic shapes is located on the floor of the cell. Such shapes are formed of a ceramic material, wettable by molten aluminium, but not wettable by the cell electrolyte. The spacing between adjacent shapes and/or the apertures in individual shapes is selected such the interfacial surface forces prevent entry of electrolyte between the shapes. The shapes may be tiles, honeycombs, cylinders, tubes, balls etc. The product metal may be collected in a sump for periodic withdrawal from the cell or withdrawn continuously or at short intervals through a selective filter that permits passage of molten metal, but not of molten cell electrolyte, at low withdrawal rates.

Abstract: PURPOSE:To eliminate interference of protective layer and attain uniform sensi tivity by covering a photoelectric conversion region with a single or a plurality of protective layers having almost equal refractive indices and setting thickness of protective layer to several tens or more times of the wavelength of incident light. CONSTITUTION:A photoelectric conversion region 2 is formed by the pn junction on a semiconductor substrate 1. An oxide film 3 consisting of a gate oxide film and intermediate insulating layer is formed by the semiconductor process on the semiconductor substrate 1. When a nitride film 5 on the photoelectric conversion region 2 is removed by the etching, etc., the light shielding layer 4 is protected by invasion of temperature in such a manner as the nitride film 4 covers to a certain degree the light shielding layer 4. After the semiconductor image sensor elements thus formed are loaded on the substrate, resin molding is carried out as the protective layer. This resin 6 should well transmit the incident light and have the refractive index near that of oxide film 3. Thickness of resin should be several tens or more times of the wavelength of incident light.

Abstract: PURPOSE:To produce a heat ray screening transparent material excellent in heat ray screening properties, mechanical strength, scuffing resistance, abrasion resistance, weather resistance and chemical resistance by coating an Ag film on a transparent base with a transparent protective film. CONSTITUTION:A heat ray screening film having one or more film layers composed mainly of Ag is formed on a flat transparent base plate such as a plane glass plate, a synthetic resin glass or their laminate. The formed film is coated with a coating liquid or paste for formation of a transparent protective film, e.g. a liquid containing a metal alkoxide of an oxide such as SiO2 or SnO2 or an oxide prepared by calcining glass paste or a liquid containing dispersed ultrafine particles of the same oxide. A bending treatment is subsequently applied to the transparent base plate by heating it. During the course of the heat treatment, the coating liquid or paste is calcined at the same time and a transparent protective film having 0.03 to 200mum thickness is formed, thus producing the objective heat ray screening transparent material.

Abstract: PURPOSE:To maintain stable magnetic properties for long time by incorporating aluminum nitride and aluminum oxide in a dielectric layer.
