IPC: H04N1/04
Filed: 1980-11-13
Abstract: PURPOSE:To obtain a cylindrical light source which is free from irregularities in the quantity of light, and has less influence of heat upon illuminating parts by providing a light diffusing material on the inside surface of a cylindrical body, introducing light from the axial direction in the end part of said cylindrical body and emitting the light from the face parallel to the longitudinal direction. CONSTITUTION:Light is introduced from light sources 2a, 2b through IR cut filters 5a, 5b from both ends 4a, 4b of a cylindrical body 1 having a light releasing opening part 7, and coated with a light diffusing material such as magnesium oxide or white fluorescent paint. The light introduced into the body 1 is uniformly diffused by the light diffusing material, and is emitted from the opening 7 of a slit shape. Arbitrary exposure control as a light source for slit exposure is possible by input voltage controlling of the light sources 2a, 2b, and  since there are no heating elements in the cylindrical body, the influence of heat  on illuminating parts is less.

Abstract: PURPOSE:To increase the withstand voltage and capacitance of a capacitor and, at the same time, to simplify the manufacturing process of the capacitor by providing silicon-oxide films on both upper and lower surfaces of an Si substrate and forming lead-out electrodes in cap-like shapes so that the electrodes can be installed easily. CONSTITUTION:A capacitor is provided with an Si substrate 4, dielectric films 6 formed of a silicon oxide on the upper and lower surfaces of the substrate 4, electric parts 8 formed on the surfaces of the films 6, the cap-like first lead-out electrode 10 which electrically connects both electrode parts 8 to each other and does not come into contact with the substrate 4, and the cap-like second lead-out electrode 12 which is fitted to the side end section of the substrate 4. Since the silicon oxide forming the dielectric films 6 is compact and high in withstand voltage, the withstand voltage of this capacitor is improved. Moreover, since the films 6 are formed on both surfaces of the substrate 4, the capacitance of this capacitor is doubled as compared with the capacitor having the dielectric film on one surface only. In addition, the electrodes 10 and 12 can be installed easily, since they have cap-like shapes which can easily put on the side faces of this capacitor. Therefore, a capacitor having large capacitance and high withstand voltage can be manufactured easily.

Title: Metal ion laser
Inventor: FUKUYA KO
IPC: H01S3/134
Filed: 1985-07-22
Abstract: PURPOSE:To stabilize the light output, by providing a constant current circuit, which stabilizes an anode current, and providing a heater control circuit, which controls a current to be supplied to a heater that heats a metal well. CONSTITUTION:When several minutes has passed after the start of discharge in a laser tube 1, Cd vapor enters a hollow cathode 4, and oscillation is started. Even if the oscillation state is reached, the change in Cd vapor brings about the fluctuation in discharge impedance. An anode current is supplied through constant current circuits 101-103. Therefore, the change in discharge impedance appears as change in output voltages of the circuits 101-103. Thus input voltages to a heater control circuit 106 are fluctuated. The circuit 106 compares the input voltages with a reference voltage and controls electric power to a Cd metal well heater 10B so that the voltages become constant and the Cd vapor pressure is optimized. In this way, both voltage and current of the discharge become constant, and the stabilized light output is obtained.
