Title: Tape loading mechanism
Inventor: KITAGAWA SHIGEHARU
IPC: G11B15/665
Filed: 1991-11-25
Abstract: PURPOSE:To obtain a tape loading mechanism capable of stably pulling out a tape by energizing a slider to rotate in a specified direction against a driving means. CONSTITUTION:A coil spring 22 is stretched between a link plate 5 and the slider 7 to energize the rotation in the specified direction. The width between two faces 21a, 21b opposing to a guide groove 21 is not constant, but a part of the width is made wider. A pair of guide pin 10 erected on a slider 7 and the pin 10 of a guide pin 11 is abutted to one face 21a of the groove 21, and the pin 11 is abutted to another face 21b. With this structure, the attitude of the slider 7 is controlled by the shape of groove 21, and a post 8 is moved along a curve 23. As a result, the tape is prevented from coming into contact with a tilted post 9 to be damaged, since the attitude of slider 7 is controlled, and only one guide groove suffices.

Title: Method for inspecting injection state of injector
Inventor: HIBINO HIROSHI
IPC: G06T7/00
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for inspecting the injection state, e.g. injection angle or torsion angle, in detail. SOLUTION: A planar light 3 is projected vertically to the axis Z of an injection port extending in the injecting direction from the injection port of a fuel injection valve 1 to produce the cross-sectional images 5a, 6a of first and second parts 5, 6 injected from the fuel injection valve 1 on the planar light 3. The cross-sectional images 5a, +6a of spray are then picked up by means of a video camera 4 disposed while inclining by a specified angle against the axis Z of injection port. Subsequently, occrdinates at the central position of the cross-sectional image are determined from the image data thereof obtained through the video camera 4 in order to calculate the spray angle between the axis of spray part passing though the coordinates at the central position and the axis of the spray port.  The calculated spray angle is compared with a preset reflectance value thus deciding whether the fuel injection valve is acceptable or not.

Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To generate a dot pattern, corresponding to number of a plurality of screen lines on request by providing only one dot pattern. SOLUTION: A 6×6 dot pattern is reduced to a half. For example, a coordinate on the 6×6 dot pattern, corresponding to a center point of a picture element of 0-row 0-column of a 3×3 dot pattern, is expressed as x=0.5 and y=0.5. Center points of four picture elements are in existence around the coordinate (x=0.5 and y=0.5) of the 6×6 dot pattern coordinate. A threshold level is given to each center point of the pixels. A threshold level of the 0-th row, 0-th column of the 3×3 dot pattern is calculated, based on each threshold level for each center point of the four pixels and a distance from the coordinate (x=0.5 and y=0.5) to the four pixel points.

The thickness of the outer layer is preferably 1-10 mm, while the thickness of the inner layer is 2-300 mm. As the thermoplastic resin, polyethylene, polypropylene and vinyl chloride can be preferably used since they provide improved feel of wood appearances.  As the wood powder, sawdust, crushed wood shavings, lumber from thinning, crushed dead tree, etc., are used, and particularly, a wood powder prepared by piling the shavings from lumber mills, partially fermenting and drying them can be properly used since it has high affinity to a resin and an average particle size is 30-500 μm.

Title: Setting method for radio frequency
Inventor: SHIBAMOTO SUKENORI
IPC: H04Q9/00
Filed: 1988-12-07
Abstract: PURPOSE:To surely receive information from a gondola without polling by a repeater by setting plural kinds of transmission frequencies different sequentially to the gondola at a start point of a station office. CONSTITUTION:When a 1st gondola G1 accommodates customers in a station (e.g. S1) and the door is closed, a radio frequency in a device in the G1 is set automatically to a setting frequency f4 so as to communicated with a setting device 2. Then the device in the station, that is, the setting device 2 uses the setting frequency f4 to designate the transmission frequency f1 to be used by the G1 to the G1. A 1st repeater R1 receives drive information from the G1 in the frequency f1 and transfers the information to a central controller 8. Thus, two or over of gondolas using the same transmission frequency do not exist in the receptible range of each repeater.

Each end of each round pipe of each pair is connected with a manifold, and hence cooling water reaches after passage through the manifold 11 and is collected with an intermediate manifold 12 directed toward the manifold 13. The water once passing through the grid and being collected, is fed to a heat exchanger. Prefluidized air passes through a wall 9 and is jetted onto the grid with the aid of a nozzle 15. The air is blown off horizontally or downwardly from the nozzle to a deflector 15a.

Title: Melting furnace for magnesium diecast machine
Inventor: KUBOTA KOHEI
IPC: B22D45/00
Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To stabilize diecast conditions by setting the gap between an ingot throw-in port and the surface of molten magnesium at a specified value or above thereby suppressing oxidation and combustion of molten magnesium. SOLUTION: The distance L from an ingot throw-in port 12 and the surface of molten magnesium 13 depends on the size of a melting furnace, the size of the ingot throw-in port 12, the surface area of the molten, etc., and a thickness for holding a shield gas layer while suppressing oxidation of the molten without breaking the atmosphere of shield gas is required. The distance between the ingot throw-in port 12 made in a furnace body 11 and the surface at molten magnesium 13 is thereby set at 50mm or longer. The thickness for holding shield gas layer is preferably set in the range of 50-150mm because a handling problem of ingot occurs when the shield gas layer is too thick. This arrangement suppresses oxidation and combustion of molten magnesium and appropriate casting conditions can be sustained.

Title: Speaker device
Inventor: KOURA TETSUJI
IPC: H04R9/00
Filed: 1994-12-14
Abstract: PURPOSE: To reduce the temperature rise of a voice coil to cope with a high input and a large output by allowing the air stream, which is generated simultaneously with oscillation of a second speaker unit, to pass the outer peripheral face of the voice coil of a first speaker unit to cool the voice coil. CONSTITUTION: Air in a speaker box 27 passes a damper 22 of a speaker unit 14 and passes a space part 32 and an air hole 28 and flows to a space part 33 and passes an air hole 29 to reach an air tube 31. When a speaker unit 30 vibrates toward the inside of the box 27, air in an air line passes the damper 22 and flows out to the inside space of the box 27. Consequently, the temperature rise of a voice coil 20 is reduced because the air passing the hole 28 not only directly cools the voice coil 20 but also cools an upper plate 18 and a center pole part 15. Since units 14 and 30 are driven with the same phase by the same signal source, the overall sound pressure is the sum of sound pressures of respective units, and a high output is obtained.

Meanwhile, an input part 7 holds the state of the drive signal detected by a detection circuit 6 and supplies it to the device 8. The device 8 compares the state of a PWM controller that is supplied from the part 5 with the state of the drive signal that is supplied from the part 7 and stores this comparison result in a storage 9.
