IPC: H04L27/20
Filed: 1980-06-04
Abstract: PURPOSE:To realize an easy formation of a modulator into an IC, by producing a base signal of in-phase component of a modulated wave and a base signal having a complementary relation with the first base signal and selecting these base signals alternately with a switch signal that is driven by a carrier signal to obtain a balanced modulation output. CONSTITUTION:The phase value is calculated based on an input signal supplied from an input terminal 1, and the phase value is generated through a phase control circuit 2 to be applied to complementary signal generating circuits 12 and 13 to the sine and cosine signals as well as to sine and cosine signal generating circuits 3 and 4. A base signal of in-phase component of a modulated wave is generated from the circuits 3 and 4, and the signal having a complementary relation with the base signal is generated through the circuits 12 and 13 by a digital process. The output signal of each of circuits 3, 4, 12 and 13 is applied to switch circuits 14 and 15 using an MOS analog switch, etc. and these output signals are switched alternately by the output of a frequency stabilizing circuit 5 having a frequency fo. The signals switched through circuits 14 and 15 are synthesized by a synthesizing circuit 9, and a balanced modulation output is produced through an output terminal 10 of a digital orthogonal modulator.

IPC: G03G15/04
Filed: 1978-06-23
Abstract: PURPOSE: To rapidly perform coyping of plural sheets by combining a data direction changeover switch and a system control mechanism.  
     CONSTITUTION: In the case of performing only one sheet or the first sheet of plural sheets, a system controller 2 commands the data read from an AD converter 4  to a memory device 5 through a control line 10 and so commands a memory switch  9 that the data in the direction of the arrow are passed in a bus 8 through a bus  direction selecting control line 11. As a result, the image data are applied to a plotter device 6 which in turn outputs the images and the data for one image plane component are taken into the device 5. Next, for the second and subsequent sheets of the multiple sheet copying, the controller 2 causes the image data for one image plane component having been stored in the device 5 to be read out and so commands the switch 9 that the data in the arrow b direction may be passed, and therefore the data are given from the device 5 to the device 6, whereby the images are reproduced. Thereby, fast copying operation is accomplished irrespective of the quantity of sheets.

IPC: C08F8/34
Filed: 1981-05-22
Abstract: PURPOSE: To facilitate the processing of polyacetylene, by processing a modified polyacetylene obtained by treating polyacetylene with a doping strong acid and then hot-contacting the processed modified polyacetylene with an aqueous medium to regenerate it as polyacetylene.  
     CONSTITUTION: A modified polyacetylene is obtained by treating polyacetylene with a doping strong acid (e.g., sulfuric acid). This modified polyacetylene is dissolved in a solvent (e.g., sulfuric acid, aqueous alkali solution) and then processed into a shape, e.g., film, fiber, powder or impregnated product. This shape can be solidified by evaporating the solvent by heating or by contacting it with a solvent (e.g., water, acetone) which is miscible with the solvent and which is a poor solvent for the modified polyacetylene. The processed product can be regenerated as the starting polyacetyelen by hot-contacting it with an aqueous medium such as water or an aqueous acid solution.

Abstract: PURPOSE:To eliminate a complicated optical system and improve ignitionability in an ignition device which performs ignition by a beam of light, by focusing the beam of light having plural wave length components to several places in a combustion chamber through a single light focusing device to perform ignition. CONSTITUTION:If an ignition instruction signal (a) in accordance with an engine condition is generated, an excitation lamp is turned on, and a laser oscillation signal (c) is output with a delay time t1 from a rise up of the signal (a) to oscillate laser light as shown by (d). A beam of light having plural wave length components oscillated by a laser oscillator 10 is focused in a combustion chamber by a focusing lens 7 to ignite a mixture.
