Title: Air purifier
Inventor: FUKUNAGA MIKIO
IPC: A61L9/16
Filed: 1988-07-28
Abstract: PURPOSE:To simplify the mounting of an aromatic and to mask the malodor re-discharged from a main body by constituting a filter set by mounting a dust collecting filter, a deodorizing filter, a filter frame and a handle part and receiving the aromatic in the handle part in a ventilative state. CONSTITUTION:The title air purifier has a main body 6 having an air blowing blade 12 and a motor 3 mounted therein and the filter set 5 arranged in the air passage 6a on the suction side of the blade 12, and the filter set 6 is equipped with a dust collecting filter 2, a deodorizing filter 3, a filter frame 4 for fixing the respective filters at the peripheral edge parts thereof and the handle part 9 formed to the filter frame 4 so as to protrude therefrom and an aromatic 11 is received in the handle part 9 in a ventilative state. Since the aromatic 11 is received in an air recirculation route as mentioned above, even when a malodor is re-discharged into room by the contaminant adhered to the dust collecting filter 2, the deodorizing filter 3 or the interior of the main body, the masking effect of the fragrance from the aromatic is displayed.

Title: Scroll compressor
Inventor: KANAI YASUYUKI
IPC: F04C18/02
Filed: 1985-08-30
Abstract: PURPOSE:To enhance reliability of a scroll compressor, by forming a metallic base material, constituting a scroll member, in large surface roughness and coating a surface of said base material with a resin material so as to improve closely attaching strength or adhesively attaching strength between the metallic base material and a resin layer. CONSTITUTION:A metallic base material 4, used for a scroll base material, uses cast iron manufactured by roughing sand used for a sandmold. The cast iron made metallic base material 4 as manufactured in such way provides considerably large surface roughness, and if its surface is coated with resin 5 filled with an inorganic filling agent of graphite or the like and organic matter of aramide fiber or fluorine contained resin and the like, closely attaching strength between the metallic base material 4 and the resin 5 can be remarkably improved. Further, the effect can be enhanced by applying an adhesive agent 6 between the metallic base material 4 and the resin 5.

Title: Package for recorded or unrecorded voice and/or video recording medium
Inventor: ROBIN JIYOFURII MAASHIYU
IPC: G09F23/00
Filed: 1990-07-19
Abstract: PURPOSE: To provide an attractive, conspicuous, rigid and practical package made of plastics material including fluorescent dye by a method wherein the package is constituted in such a way that light produced by the material due to its fluorescent characteristic responding to its surrounding light is preferentially emitted from one or more selected portions of the package. CONSTITUTION: Upright sections 3 and 4 are arranged at a base section 2. The base section 2 is formed of plastics material. A lid section 1 is formed of plastics material such as polymethyl methacrylate, polystylene, acryl or polycarbonate materials containing one or more fluorescent plastic dyes. Almost all light generated by fluorescent light produced in response to the surrounding light is enclosed within the material and the light is emitted out of the material when the light is scattered. Since the light scattering is automatically produced at some sharp edges of the material, the lid 1 may produce intensified light from around the sharp edges. The light is seen bright due to an effect of intensified emitted light caused by the light emitted from a smaller lid region as compared with an entire light collecting/fluorescent volume.

Title: Method and device for forming hologram
Inventor: HOSOE HIDE
IPC: G03H1/04
Filed: 1989-07-21
Abstract: PURPOSE:To form the concentrical patterns of a hologram with high drawing accuracy by forming a photoresist film on a substrate at the point of the time when a photoresist soln. spreads sufficiently on the substrate, then exposing the concentrical patterns of the hologram onto the photoresist on the substrate and subjecting the photoresist to an after-exposing processing. CONSTITUTION:The photoresist soln. is dropped to the central part of rotation of the photoresist substrate B by rotating the substrate B and the rotation of the substrate B is stopped at the point of the time when the soln. spreads sufficiently to the peripheral part of the substrate B, then the photoresist film is formed on the substrate B. The substrate B is again rotated and the concentrical patterns of the hologram are exposed to the photoresist on the substrate B by a light projecting means 2 of a laser beam and a moving means 3 for moving this light projecting means 2 in the direction orthogonal with the revolving shaft 13 of the hologram B; thereafter, the photoresist is subjected to the after-exposing processing. The concentrical patterns of the hologram are formed on the photoresist film uniformly with the high drawing accuracy in this way.

IPC: B24C9/00
Filed: 1998-06-20
Abstract: PROBLEM TO BE SOLVED: To quickly eliminate static electricity from blast particle in contact with an inside surface of a working chamber and to smoothly collect a used blast material by forming a conductive layer on the inside surface of the blast working chamber and grounding the conductive layer. SOLUTION: A blast nozzle 2 is provided at the inside of a blast working chamber 1, blast particle supplied via a blast material supply pipe 3 is blown on a work 5 by taking blast particle on high speed air current from an air feed pipe 4 and blast working is performed. A bottom part discharge side is connected with a collecting device via a collecting pipe 6. By sticking a copper plate to the whole surface on an inside surface of the blast working chamber 1, a conductive layer 7 is formed and is grounded via an earth wire 8. Because electric charge is immediately discharged via the earth wire 8 when particle charged by frictional static electricity comes into contact with the conductive layer 7, sticking and staying of particle on the inside surface of the working chamber 1 are eliminated. By impressing ac voltage on the conductive layer 7, static electricity can he eliminated.

Title: Fullness detector for stacked paper sheets
Inventor: HIGUCHI TERUYUKI
IPC: B65H31/00
Filed: 1988-07-30
Abstract: PURPOSE:To detect a state of fullness in stacked paper sheets so accurately without any malfunction by setting up a detecting lever in a shift member being vertically shifted, and constituting it so as to recognize a paper surface level as this detecting lever and a sensor are opposed to each other only at a time when the shift member is in a specified position. CONSTITUTION:When a reject note is found out at a discriminating part, a shift member 104 emits a reject signal, rotating paper discharge rollers 101, 102. At this time, the shift member 104 is situated in a home position, stacking paper sheets in order from a receiving port 103 and housing them, and when a topmost paper sheet 140 is reached to the specified level, a paper surface detecting lever 130 goes across each optical path of sensor means 131a, 131b, through which a fact that the number of stacked paper sheets becomes more than the specified quantity is detected. On the other hand, when such a paper sheet as oblivious of taking out is detected at a reception port, the member 104 is moved down, and the forgotten paper sheet is housed on this member 104. Thus, the sensor means 131a, 131b detect a paper surface level only at the specified position of the member 104 vertically moving, and at another position, they separate from this member so that no malfunction occurs at all.
