Title: Transfer-repair-stack-extracting mechanism of tabular article
Inventor: KITAGAWA JOHAN
IPC: B27D1/00
Filed: 1987-09-02
Abstract: PURPOSE: To successively conduct repair work for lacking portion of board article including transfer of board article to be repaired and loading of that after repaired by means of transfer, repair and loading mechanism. CONSTITUTION: Regular-shaped repair hole is bored by cutting board article to be repaired by rotary circular cutter 13. At this stage, repair disk supply mechanism C supplies repair disk to repair disk joint mechanism B. The repair disk housed in circular recession 62a is held by the joint mechanism B and fit-inserted into the repair hole of the board article to be repaired. Because the repair disk has been cut obliquely at the circumferential face to form wedged clearance broadening upward in the sate fit-inserted into the repair hole, hot melt adhesive is injected for painting into this clearance.

Title: Semiconductor device
Inventor: TANAKA KAZUO
IPC: H01L21/768
Filed: 1987-09-02
Abstract: PURPOSE:To reduce a chip area, by interposing a TiN layer between connections of the first wiring layer or first semiconductor to the second wiring layer or second semiconductor. CONSTITUTION:An active region 101 containing an N-type or a P-type impurity is formed on a semiconductor substrate 100 and all sides of the active region are surrounded with insulating films 102; films of silicon oxide, silicon nitride, a polyimide resin, and the like. A TiN layer 103 is formed on an opening 104 provided on the active region. Then its active region 101 of this element is connected to a polycrystal silicon layer 105 through the opening 104. This step not only prevents characteristic failures such as an electric leakage and so on but also contrives to make the element fine without enlarging a polycrystal silicon width at the opening part.

Title: Liquid crystal display device
Inventor: YOSHIDA HIDESHI
IPC: G02F1/1333
Filed: 1992-08-19
Abstract: PURPOSE:To improve display performance by causing the phase sepn. of the compatibilized matter of a photosetting resin material contg. monofunctional monomers and oligomers and liquid crystals by photoirradiation, thereby dispersing the liquid crystals into a polymer. CONSTITUTION:This liquid crystal panel 10 is constituted by sealing a liquid crystal layer 16 between a pair of glass substrates 12 and 14 facing each other. This liquid crystal layer 16 is formed by causing the phase sepn. of the compatibilized matter of the photosetting resin material contg. the monofunctional monomers and the oligomers and the liquid crystals by the photoirradiation to disperse the liquid crystals 18 into the transparent polymers 22 in the form of liquid crystal capsules 20. The monofunctional monomers or the monomers having >=200 mol.wt. are preferably selected in such constitution. The former improves the relation between an impressed voltage and transmittance and the latter lowers the evaporation of the photosetting resin material in a vacuum. The monomers which do not possess sections leading to polarities, such as ether bonds, are preferably selected. Further, a combination in which the solubility parameter of the photosetting resin material is smaller than the solubility parameter of the liquid crystals 18 is more preferable.

Title: Non-metallic inclusion removing device in molten metal
Inventor: YAMADA MASAHIRO
IPC: B22D11/11
Filed: 1993-09-06
Abstract: PURPOSE:To turn the tundish and the coil and efficiently work the coil by keeping the space at the end of the coil so that the end part of the coil may not be brought into contact with the tundish in the turning operation. CONSTITUTION:A electromagnetic force generating coil 12 is of the semi- cylindrical shape along a side wall 1a of a tundish 1, and the center 12b of the inner surface of the tundish side is curved in the arc shape. The end part 12c of the inner surface of the coil is brought close to the outer surface 12a toward the tip, and the space between the end part and the side wall 1a of the tundish 1 becomes larger. Thus, the tundish 1 and the coil 11 can be arranged to be moved and brought as close as to each other by the turning. The area of the building can be reduced, and the tilting device of the tundish hot recycling can be simplified thereby without lowering working efficiency of the coil 11. The manufacturing cost of the high grade steel can be reduced accordingly.

Title: Tape printer
Inventor: NAKAJIMA KENICHI
IPC: B41J15/16
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To remove a slack in a printing tape, maintain printing quality and suppress a wasteful consumption of the printing tape without feeding the printing tape in the normal direction by providing a structure wherein a rear feed roller is rotated reversely with a front feed roller stopped in a tape printer. SOLUTION: When a tape feed motor 58 is rotated reversely for a prescribed period (several seconds), a feed roller 41 rotates reversely and thereby feeds a printing tape Tp reversely only slightly. In such case, the third idle gear 56 engages with a rotation blocking block 62, putting a lamination roller 42 in a blocked state, and the printing tape Tp gets into a tensioned state between the feed roller 41 and the lamination roller 42. That is, the feed roller 41 rotates reversely and thereby feeds the printing tape Tp reversely, and idles and stops after the printing tape Tp is tensioned. The reverse feed of the printing tape helps remove a slack in the printing tape without feeding normally the printing tape.

Title: Air-conditioner
Inventor: KATO KOJI
IPC: F04C28/06
Filed: 1994-09-16
Abstract: PURPOSE: To reduce the generation of vibration noise of a compressor and an outdoor unit without reducing torque during synchronous starting by a method wherein an initial commutation frequency during synchronous starting from a low frequency is started with a frequency higher than the resonance frequency of a machine system consisting of a compressor, a unit, etc. CONSTITUTION: An air-conditioner comprises an AC source 1, such as a commercial AC source; a converter part 2 to convert AC to DC; an inverter part 3 to invert a current fed from the converter part 2 to a three-phase AC; a control part 4 to control the inverter part 3: a compressor motor 8: a position detecting circuit 9 to detect the position of a rotating rotor 6: and a current detecting circuit 10 to detect a current flowing to the inverter 3.

Title: Packing plate for drum brake
Inventor: NIWA SHOZO
IPC: F16D65/00
Filed: 1988-09-06
Abstract: PURPOSE:To prevent a brake noise from occurring by having two steel sheets joined together via a resin layer (consisting of polypropylene 60wt.% and ethylenepropylene diene rubber 40%), in a packing plate. CONSTITUTION:The front and back of a packing plate 1 are all made up of metalforming steel sheets 1a, 1b, and a resin layer 1c is interposed between these sheets and subjected to thermocompression bonding as a whole by means of a press machine. A loss factor of resin to be used is almost constant in an extensive temperature area, therefore such one that a damping characteristic is not lowered even at time of a temperature rise is desirable to be used. Accordingly, resin consisting of polypropylene 60w.t% and ethylenepropylenediene rubber 40wt.% is suitable for this condition, which absorbs vibration in an anchor 2 when a brake is applied, so that vibro-dampability in the packing plate is thus improved. Thus a brake noise is preventable.

Title: Method for forming phosphor screen for color picture tube of beam index type
Inventor: TERADA KATSUMI
IPC: H01J29/28
Filed: 1982-12-16
Abstract: PURPOSE:To provide an index beam of large intensity, by providing a film of a substance transparent and conductive and having pinholes therein allowing vaporized gas to pass through the same and then subjecting the film to a baking process. CONSTITUTION:After formation of index stripes thereon, a panel 9 is fixed to a rotatable device for painting 10. With a shutter 11 being made integral with the device for painting applied to the panel not to smear the circumferential portion of the panel, a protect film is spread over the panel with a spray gun 12 while the device for painting is rotated, the protection film being of a material transparent and conductive and having pinholes therein allowing vaporized gas to pass through the same. Since the protect film 20 has suitable cracks or pinholes therein, all organic substances can be vaporized without dispersing the index phosphor stripes 6 during the baking process. Since the protect film is transparent and conductive, the loss of the electron beam passing through the same is small and the film also provides good transparency for the beam coming from the index phosphor material.
