Title: Copying machine with original reader
Inventor: KATAOKA HIROSHI
IPC: H04N1/04
Filed: 1990-10-24
Abstract: PURPOSE:To attain reading of a digital data in a same way of reading in the usual copy mode and to eliminate distortion of a picture by arranging a CCD reader onto an optical axis. CONSTITUTION:A CCD read means 15 is provided side by side on a base member 6a to fix a lens unit 1 for magnifying or reducing an original and a lens changeover means 4 is formed, which replaces the arrangement of the lens unit 1 of the base member 6a and the CCD read means 15. The base member 6a is moved at the reading of a digital data to arrange the CCD read means 15 onto an optical axis in place of the lens unit 1. Since the digital data is read in the entirely same way as that of the usual copying mode, distortion of a picture is not caused.

Filed: 1987-11-13
Abstract: PURPOSE:To facilitate the production of plural oxide superconductor of good quality by using flux containing vanadium oxide, when the crystal of plural oxide superconductor is allowed to grow by the liquid-phase growth method. CONSTITUTION:A solution 7 of flux containing vanadium oxide such as V2O5, and raw materials of plural oxide superconductor such as a mixture of Y2O3, 2BaO, and 3CuO, is charged in the crucible 3 in the single crystal-pulling up unit. Then, the solution 7 is heated with heater 2 at about 1,200-1,300 deg.C and cooled down to about 700 deg.C. Then, the seed crystal such as of Y-Ba-Cu-O single crystal on the top of the pulling-up shaft 8 is allowed to contact with the solution 7 and the oxide superconductor is pulled up, as an oxygen gas is fed from pipe 12. Thus, crystals of oxide supercouductor with high homogeneity of superconductive transition point and large critical current can be produced with high reproducibility.

Abstract: PURPOSE:To appropriately control the flow rate even in the case of the mixed fluid of the liquid with the gas by providing a throttling part on the inlet side of the flow passage of a valve box, and providing a variable throttling part on the outlet side of the flow passage. CONSTITUTION:An inlet side throttling part 136 where the flow rate is adjusted by an inlet side valve 135 is provided on the inlet 130 side of the flow passage 132 of a valve box 104, and a variable throttling part 110 where the flow rate is automatically adjusted by a differential pressure actuating valve 118 is provided on the outlet 131 side of the flow passage 132. The fluid to flow into the inlet 130 of the flow passage 132 is successively passes through the inlet side throttling part 136 and the variable throttling part 110, and is discharged from the outlet 131. When the gas in the mixed fluid passes the inlet side throttling part 136, the pressure loss of the gas is small in the case where the gas is same as the liquid in volume, and the flow rate becomes higher than the prescribed value. Thus, the liquid in the flow passage 132 is subjected to the pressing force of the gas, and the liquid pressure is increased, and the differential pressure between the primary side S1 and the secondary side S2 at the variable throttling part 110 is increased, and the differential pressure actuating valve 118 is actuated in the valve-closing direction to close the variable throttling part 110.

Title: Excimer laser
Inventor: MINAGAWA TADAO
IPC: H01S3/097
Filed: 1990-10-29
Abstract: PURPOSE:To prevent deterioration of laser gas by coating an insulator of contact gas in a laser housing, a surface layer of a structural material with inorganic fluoride. CONSTITUTION:Compound having an excellent mechanical strength is used as a ceramic insulator 61. Fluoride or its mixture which is easily formed is used as inorganic fluoride coating 62. The insulator 61 is formed with the coating 62, and mounted at an insulator position of an excimer laser. In the insulator of the configuration, the insulator itself is not brought into contact with the fluorine gas by the coating 52 of the surface layer, and hence generation of impurity gas from the insulator can be suppressed. Since the coating 62 does not react with fluorine gas at all even in contact, impurities are not generated from the coating. Thus, deterioration of laser gas is alleviated, and operating efficiency of the excimer laser is improved.

Filed: 1985-12-24
Abstract: PURPOSE:To decide whether the polarity of an output signal of a connection destination is active or nonactive by providing a circuit storing the active polarity of an input signal and a polarity decision circuit of the input signal in response to the storage content. CONSTITUTION:When a reset signals is fed to an input terminal 2, a three-state buffer 3 is turned on, a signal at a terminal 1 is inputted via connection lines 6, 8 as a data a D-type FF 4. In this case, since the reset signal is fed as the clock of the FF 4, the FF is latched at the leading and when the output of the FF 4 goes to '1' when the nonactive polarity of the terminal 4 is logical '1' and the output is '0' when the output is logical '0'. After the end of reset, the output of the FF 4 and the input signal to the terminal 1 are inputted to an exclusive NOR circuit 5 after the end of reset and the polarity of the input signal is inverted. Thus, the information relating to the nonactive polarity after storage is dissident at the reset only, then the signal of an input signal connection line 10 represents the active polarity to discriminate the polarity of the output signal of connection destination.
