Patent JP-S5824231-A (JP)
Title: Digital-to-analog converter
Inventor: KOGA AKIHIKO
IPC: H03M1/06
Filed: 1981-08-04
Abstract: PURPOSE:To prevent the monotony of an output current from being spoiled when a digital input varies, by providing a current mirror circuit with a holding gate between the output terminal of a DA converter and a power source. CONSTITUTION:A current mirror circuit 40 provided with a holding gate is provided between the terminal 36 of a DA converter 6 and the terminal 37 of a power source VD2. When a clock signal phi synchronizing with a digital input to the gate of the transfor MOSFET42 of the circuit 40 has a high level, an FET42 turns on to short the gates of FETs 41 and 43, and the circuit 40 becomes equivalent to a current mirror circuit. When the FETs 41 and 43 are equalized in gm, equal currents flow through the FETs 41 and 43. When the signal phi has a low level and the FET42 still turns off, the gate potential of the FET43 is unchanged because of charges accumulated in a capacitance 44, and the same current flows continuously. Therefore, even if the digital input varies and the output current I1 of the converter 6 decreases temporarily and increases to a high value, the output current flowing to the drain of the FET43 has no abnormal waveform, thus obtaining the monotony.

Abstract: PURPOSE:To apply various kinds of processing to a color signal without causing deterioration in the signal by providing a 1st sampling means, a 2nd sampling means, a color difference data forming means, a color difference data processing means, a 1st arithmetic means, a control means and a chrominance carrier signal forming means. CONSTITUTION:Color difference signals 106, 107 are generated by using 1st sampling data 102, 104 obtained through sampling a chrominance carrier signal based on a clock signal phase-locked with a reference phase of the chrominance carrier signal and 2nd sampling data 103, 105 with an opposite phase to that of the 1st sampling data 102, 104. The arithmetic processing is controlled in response to whether or not a color difference data subjected to various kinds of processing represents data of an odd number when various kinds of processing are applied to the generated color difference data 106, 107 and a chrominance carrier signal is generated from the arithmetic data subjected to arithmetic processing. Thus, the signal processing is applied to the chrominance carrier signal without deteriorating the signal.

Title: Charge coupled device
Inventor: TSUKADA NORIAKI
IPC: H01L29/762
Filed: 1981-08-04
Abstract: PURPOSE:To obtain the charge coupled device, which can respond at high speed and has high charge transfer efficiency, by utilizing an epitaxial layer having high mobility as a charge transfer channel. CONSTITUTION:When an impurity is doped only to GaAlAs layers 12, 14 and is not doped to a GaAs layer 13, electrons (carriers) generated by the doners of the GaAlAs layers 12, 14 due to electronic affinity are trapped to the GaAs layer 13 having low energy. The mobility of the electrons of the GaAs layer 13 is extremely increased because there is no center of the scattering of the impurity through doping in the layer. Accordingly, the speed of response is extremely accelerated when using the high-speed mobility effect.

Title: Overvoltage suppressor
Inventor: SASA CHIKAGE
IPC: H02H9/04
Filed: 1990-05-14
Abstract: PURPOSE:To suppress an overvoltage value to a withstand voltage or less of an electric device by setting a self-igniting voltage of a thyristor to a predetermined range between a withstand voltage for protecting the device and an overvoltage to be detected by overvoltage detecting means. CONSTITUTION:The line voltage of a secondary winding 22 during normal operation is V0, the line voltage of the winding 22 when a controller 2 detects an overvoltage to generate an optical igniting signal is V1, a voltage for self- igniting a VBO-free optical thyristor 3 is V2, and withstand voltage value of the winding 22 and a cycloconverter 11 is V3. In order to suitably protect the winding 22 and the cycloconverter 11, it is necessary to set the values of the V0, V1, V2, V3 to V0<V1<V2<V3. If one-line ground-fault occurs in an AC power source circuit 25, an overvoltage is generated at the winding 22. If the line voltage reaches the V1, the controller 2 detects the overvoltage, and outputs an optical ignition signal to the thyristor 3. There is a time delay from when the controller 2 detects the overvoltage to a time t3 in which the optical ignition signal is output.

In this case, the delivery of the inks is controlled in timing, during which the thickness of the coloring material fixing liquid layer impacted on the material to be printed becomes nearly even. The timing of this time is set preferably on the basis of the penetration speed of the coloring material fixing liquid into the material to be printed.  The longer the time lag between the delivery of the ink and that of the coloring material fixing liquid becomes, the larger the delivering amount of the ink is set.
