Title: Molding integrally molded of urethane resin and metal, and its manufacture
Inventor: HATTORI EIICHI
IPC: B29K75/00
Filed: 1988-05-30
Abstract: PURPOSE:To enable urethane resin to be stuck onto even the flat surface of a coated metallic body, while the polyurethane resin layer after molding may be prevented from occurring of its discoloration and property-deterioration with easy injection molding by using the isocyanate adhesive containing a specified residual amount of free cyanate in the combination of the adhesives of phenol/butyral type and isocyanate type. CONSTITUTION:When the surface of coated metallic body 1 preliminarily primed with the adhesive 2 of phenol/butyral type is finally coated with the isocyanate adhesive 4 having free isocyanate containing 1 to 10wt.% of relatively low residual amount, thermoplastic polyurethane resin 3 adheres perfectly to the metallic surface firmly, even if the surface of the coated metallic body is relatively flat. Accordingly, since the curing under baking at high temperature higher than necessity may be omitted, the quality deterioration and discoloration, etc. for the layer of thermoplastic polyurethane resin do not occur, and its physical property becomes stable and excellent. When thermoplastic polyurethane resin is injection-molded, water-absorbing treatment is applied to the free component of isocyanate under the atmosphere of room temperature and much moisture and the component are reacted, whereby the both materials are integrally molded mutually.

Title: Image forming method
Inventor: TOKUNAGA HIROSHI
IPC: H04N1/40
Filed: 1984-06-28
Abstract: PURPOSE:To reproduce an image containing chromatic and achromatic colors with high sharpness, high accuracy and easy control, by selecting an optical device so that the chromatic signal level can be separated from the achromatic signal level. CONSTITUTION:The output levels shown in the figures are obtained by the incidence of light of each wavelength band given from a dichroic mirror 40 and through a CCD42 on which the light containing the BG component is made incident and a CCD41 on which the light containing the R component is made incident respectively. The output [C'] given from the CCD42 is inverted at a signal processing part 43 and synthesized with the output [R] given from the CCD41. Based on this synthetic signal, the beams of light quantities corresponding to each color level are irradiated to a photosensitive drum from a latent image forming circuit. Thus latent images of each color corresponding to the potentials corresponding to the synthetic signal waveform are formed to a photosensitive layer of the drum. For these latent images, the chromatic levels (G, B and C) of the 1st group and the chromatic levels (M, Y and R) of the 2nd group are formed at both sides of the achromatic levels (w and b). These chromatic levels can be separated from the achromatic levels.

Title: Electronic variable impedance device
Inventor: OOKUBO YUUICHI
IPC: H03H11/46
Filed: 1981-08-28
Abstract: PURPOSE:To obtain an electronic variable impedance device which responds to a specific control signal and then reduces its input impedance extremely, by arranging a diode and a control transistor (TR) under the control of the specific control signal. CONSTITUTION:A specific control voltage Vc is applied to a control terminal Tc to turn on a TRQ7, whose collector current Ic is supplied to anodes of diodes D4 and D5. Simultaneously, a TRQ8 is also turned on and its collector current is supplied to a TRQ9. Resistances R5 and R6 are set to an equal value, so the collector current of the TRQ7 is equal to the collector current of the TRQ8. Further, resistances R7, R8, and R9 are also set to an equal value, so collector currents of TRs Q10 and Q11 are equal to that of the TRQ9. Therefore,  specific current Ic flows through the diodes D4 and D5 and the AC resistance of the D4 and D5 is reduced extremely, reducing the input impedance to a sufficiently small value.

Abstract: PURPOSE:To effectively investigate the cause of a trouble and to perform the processing of recovery by integrally constituting a keyboard and a display part to have an input and display unit and attachably/detachably mounting on a control part main part. CONSTITUTION:The keyboard 12a is integrally constituted with the display part 12b to have the input and display unit 12 and attachably/detachably mount the input and display unit 12 on the control part main body 11 through connectors 11a, 12d. A processor incorporated in the control part main body 11, at the time of connecting the input and display unit 12 to the control part main body 11, uses a signal from a connecting state monitoring part 12c to identify a transitional state on the way of a connection or a completely connected stable connection state. At the time of the completely connected state, an initializing processing is automatically executed to the input and display unit 12 to validate the operation of the input and display unit thereafter. Thereby, even when a power source is not disconnected, the input and display unit 12 is connected to the control part main body 11 to effectively investigate the cause of the trouble and to perform the processing of the recovery.

Abstract: PURPOSE:To quickly transmit information between a receiver and a repeater panel without lowering information transmission capacity by establishing a backup transmission line using effectively line abnormality information to be obtained beforehand. CONSTITUTION:When the disconnection or the line abnormality of main transmission lines 3a, 3b is detected in a routine monitoring state, this line abnormality is stored in the memories of the receiver 1 and the repeater panels 2a-2e.

Title: Locking method for welding wire in arc welding
Inventor: OOKUMA YUUJI
IPC: B23K9/133
Filed: 1981-08-27
Abstract: PURPOSE:To feed a welding wire easily and to stabilize its locking characteristic by pressurizing the wire at one point on the end side of its preceding end and rotating the same around the axis of the wire thereby applying torsional force and plastic deformation to the wire. CONSTITUTION:A welding wire fed by feed rollers 6 is rotated around its axis under the pressurizing forces F, -F developed by pressure-sandwiching rollers 5 in the part between a point P1 and a point P2, whereby torsional force is applied to the wire 1. Therefore, the wire deforms plastically to assume a spiral shape 7 three-dimensionally. If welding is begun while the wire is kept fed in said state, the preceding end of the wire 1 draws a circular locus. Further a feed mechanism 3 is moved along the weld line; therefore the preceding end 4 of the wire advances by drawing the loci when a coil spring is viewed diagonally. In other words, the wire locks with respect to the weld line and locks toward horizontal and vertical directions as well.
