Title: Power source regulator circuit
Inventor: OOHATA YASUO
IPC: G05F1/56
Filed: 1977-09-21
Abstract: PURPOSE: To stabilize output as well as simplify constitution by using enhancement type electric field effect transistor for control transistor.  
     CONSTITUTION: As the output voltage Vout rises, the base voltageVA of the amplifying transistor Q1 is increased, and because the emitter potential of the transistor Q1 is kept constant by means of the Zener diode DZ, the voltage VBE between the base emitters of the transistor Q1 rises to increase current flowing in the transistor Q1. The voltage drop of the resistance RO becomes greater and the gate voltage of the enhancement type electric field effect transistor Mn is therefore lowered, so that the drain current of the electric field effect transistor Mn is reduced, the voltage drop between drain and source becomes greater, and the output voltage Vout is reduced, thus resulting in the stabilization of the output voltage. And, when the output voltage is lowered, the gate voltage of the electric field effect transistor Mn becomes greater to raise the output voltage Vout

Filed: 1988-05-10
Abstract: PURPOSE:To display a moving image with natural halftones by converting an analog video signal into discrete data and transferring the result of halftone processing to a bit map memory in parallel, and then transferring the data in the memory to a binary display device. CONSTITUTION:A vertical synchronizing signal outputted by the video signal processing circuit 102 in an image input adapter 101 begins to be monitored in response to a processing start signal from the CPU 107 in information processing equipment 100. When the signal is inputted to an image data controller 104, a halftone processing circuit 105 processes it into halftone image data, which is stored in a memory 106. When the input processing is finished, the CPU 107 sends a signal for sending the data in the memory 106 to a VRAM 111 to a DMAC 108 to perform transfer and the processing from the image input to the transfer is repeated in a fraction of tens of seconds until an input signal for stopping the processing is inputted on a keyboard 113. Thus, an NTSC video signal 115 is displayed as a moving image on a display part 112.

Title: Amplifying circuit
Inventor: SATO KOJI
IPC: H03F1/34
Filed: 1989-05-08
Abstract: PURPOSE:To reduce the noise level due to the noise superposed on power and to reduce the output signal for circuit trouble by setting negative feedback of a negative feedback amplifying circuit to such extent that it cancels the power noise. CONSTITUTION:A resistance R and a capacitor C are connected between the collector and the ground of a transistor TR Q2. The capacitor C is inserted to prevent the resistance R from being related to the DC potential of the base of a TR Q1. The resistance R is provided as the balancing resistance to cancel the change of the signal, which flows to the emitter side of the TR Q2, through the base side of the TR Q1 with respect to the signal appearing as the change of a DC power VCC in the collector of the TR Q2. Thus, when the resistance R is properly set, the error signal due to the power noise is not generated, and the noise level is reduced, and the output signal for circuit trouble is re duced.

Title: Manufacture of amorphous semiconductor
Inventor: MORI KOUSHIROU
IPC: H01L31/04
Filed: 1981-07-20
Abstract: PURPOSE:To improve amorphous Si solar batteries by a method wherein a distance between the substrate and the electrode is varied at the time of depositing. CONSTITUTION:A P type layer 18, an i type layer 19 and an n type layer 20  have thickness of 100Angstrom , several thousands Angstrom and 3,000Angstrom , respectively. Deposition in carried out by adding B2H6 to SiH4 for the p type layer and adding PH3  to SiH4 for the n type layer. At present, to form p type amorphous Si and control activation energy at 0.2-0.3 eV, it is required that B2H6 is added to SiH4 in percentage of ca. 1%. Decomposing speeds of SiH4, B2H6 and PH3 are normally different from one another, but such decomposing speeds and film property can be controlled by setting a distance between the substrate and the electrode at a proper value. In other words, a distance between a substrate 9 and an electrode 8 within a vacuum vessel 7 is movable vertically using an electrode serving as a substrate holder and also another electrode, which electrode is raised or lowered by using a combination of gears 11 and 12 and by rotating the gear 11 fixed to a shaft of a motor 13.

Title: Oxidation of pitch fiber
Inventor: MATSUMOTO TADAYUKI
IPC: D01F9/15
Filed: 1988-05-10
Abstract: PURPOSE:To improve the efficiency of infusibilization treatment by spinning a pitch, carrying out oxidation thereof as an infusibilization reaction while heating the pitch yarn in steps and in such a way as to release almost equal heat in the respective steps. CONSTITUTION:A pitch such as coal-based pitch or petroleum-based pitch is spun. The resultant pitch yarn is subjected to infusibilization treatment by forcing the yarn to run through an infusibilizing apparatus using rollers in which an pattern of temperature increase is set in steps and in such a way that heat release value may be almost equal in the respective steps between the glass transition temperature of the pitch and the maximum treating temperature. The resultant infusibilized yarn is subsequently subjected to carbonization treatment and graphitization treatment, thus troubles such as adhesion of mutually adjacent fibers, fusion and combustion in infusibilization treatment are prevented.

Title: Emulsion polymerization
Inventor: BABA AKIKAZU
IPC: C08F2/00
Filed: 1982-07-02
Abstract: PURPOSE:To obtain stably a low-foaming resin emulsion, by emulsion-polymerizing an unsaturated monomer by using a specified compound as an emulsifier. CONSTITUTION:In producing a resin emulsion by emulsion-polymerizing an unsaturated monomer, use is made of an emulsifier which is a compound of the formula (wherein n is 4-300, and X and Y are each H or a salt-forming substance). This process can provide a low-foaming resin emulsion, because the emulsifier used can exhibit its effectiveness in such a manner that all of the moieties of the emulsifier molecule have a considerable associatability with water used as the media for the emulsion polymerization and the resin emulsion, while the molecule has ionically dissociatable carboxyl groups on both of its ends and therefore it shows an ability to solubilize the unsaturated monomer in water and an ability to stabilize the dispersed particles produced by polymerization of the monomer.
