IPC: H04N1/04
Filed: 1985-11-05
Abstract: PURPOSE:To improve the efficiency of an exposure lamp by using the signal of a position detection sensor provided to a transfer drum driven while being wounded with a transfer paper sheet therearound as a control signal lighting an original exposure lamp so as to turn on/off the exposure lamp in a proper timing. CONSTITUTION:A position detection sensor 33 is provided this side than the position of a conventional sensor and the power supply for the exposure lamp 6 is applied before a scanning platen 4 reaches the position of a picture tip sensor 23. When a copy key is turned on, a signal from the sensor 33 is led to light the exposure lamp 6. Then a signal from a sensor 20 is led to start forwarding the scanning platen 4. When the picture tip sensor 23 senses the platen 4, the reading of an original 3 is started and when the reading of the original 3 is finished, the platen 4 is stopped thereby turning off the lamp 6. Then the platen 4 is reversed backward, and when a home position sensor 22 detects the platen, the platen is stopped.

IPC: B23K20/00
Filed: 1983-12-29
Abstract: PURPOSE:To perform gas press welding with high reliability by starting press welding while applying sliding contact motion between the butt contact surfaces. CONSTITUTION:Reinforcing steel bars 1, 2 are butted to each other and the pressurizing force is initially set zero. Heating by a ring burner for press welding of the reinforcing bars is started under the operation of a vibrator 7. The state equal to zero pressurization is maintained from the start point of heating until the temp. in the contact part of the reinforcing bars attains the temp. adequate for press welding. The pressure is increased stepwise or gradually at the point where the adequate temp. is attained until finally the prescribed pressurizing force is attained. The stepwise pressurizing force is obtd. by operating an electrically driven pump by conduction of pluse currents thereto according to a prescribed program. The pressurizing state under the prescribed pressurizing force is maintained until the butt gas is closed. The operation of the electrically driven pump is stopped when the butt part is slightly compressively bulged and when not butt gap is observed at all. The pump is again operated to pressurize the butt part where the pressurizing force is decreased by half. The joining is completed where the compressive bulging attains a prescribed rate.

Abstract: PURPOSE:To prevent a decline in the number of the substantial quantizing bits of chrominance component and reduce the variation of the hue and color saturation of output video signal, by performing gain amplification on carry chrominance signal component in input video signal so as to amplify the burst amplitude to a prescribed level. CONSTITUTION:Amplitude of horizontal synchronizing signal of inputted 1 video signal are fixed by adjusting 2 gain of the horizontal synchronizing signal and luminance signal Y and chrominance signal C are separated 31 by means of an LPF and BPF, respectively. Then burst amplitude in the chrominance signal component is amplified to a prescribed level by controlling 32 gain of the luminance signal Y. When the signals C and Y are mixed 33 with each other, video signal, with the amplitude of the signal, C being adjusted to a prescribed level, is obtained. Then the video signal is AD-converted 3 and digitally Y/C separated 34 again, and then, the chrominance signal C component is written in a memory after they are digitally color-demodulated. When such constitution is used, variation of hue and color saturation in output picture can be reduced to the utmost without lowering the number of substantial quantizing bits even if the amplitude of the chrominance signal is small when the video signal is AD-converted.

Abstract: PURPOSE:To obtain an optical branching device miniaturized and with superior branching ratio and low loss by providing a sector optical waveguide coupled with an optical waveguide for input and with refractive index less than that of the optical waveguide for input, and plural optical fibers for output arranged along the arc side of the sector optical waveguide. CONSTITUTION:This device is equipped with the optical waveguide 2 for input, an optical waveguide 1 for radiation with refractive index less than that of the optical waveguide 2 for input and formed in sector shape and with the pivotal part of the sector of which the optical waveguide 2 for input is coupled, and the plural optical fibers 3 for output whose terminal parts, the diameters of which being thinned, are arranged so as to be butted with the arc side of the sector optical waveguide 1. Therefore, it follows that a waveguide mode is radiated from the optical waveguide 2 with high refractive index to the optical waveguide 1 with low refractive index, and incident light from the part of the sector can be spread and propagated uniformly in a direction of the arc side. Also, since the terminal part of the optical fiber 3 for output whose diameter is thinned is arranged at the arc side, the area ratio of a core part on which the light is made incident effectively can be heightened, which improves coupling efficiency. In such a way, it is possible to obtain the optical branching device of 1XN miniaturized and with low loss and with superior branching ratio characteristic.
