Patent JP-S61177475-A (JP)
Title: Lighting device
Inventor: YANO HIDEAKI
IPC: G03G21/00
Filed: 1985-02-01
Abstract: PURPOSE:To eliminate deterioration and deficiency of picture quality and, at the same time, to prevent useless consumption of toner, by providing a slit member which forms a clearance having parallel linear side edges between lens members and an image carrier. CONSTITUTION:Luminous fluxes radiated from LEDs 12 are shaped to rectangular luminous fluxes by means of light intercepting members 13 and narrowed their spread angles theta by means of lens members 14, and then, become parallel band-like luminous fluxes having linear side edges after passing through a slit member 23. The band-like luminous fluxes are irradiated upon an image carrier 6 in the shape of a rectangle with high intensity of illumination and no other luminous flux does reach the image carrier 6. Therefore, the light quantity distribution on the surface of the image carrier 6 becomes such that no light is leaked to an image area A and only an no-image area A can be illuminated sharply with high intensity of illumination. Moreover, since even the light quantity at the trough part in the light quantity distribution is higher than the level required for removing electricity from the image carrier 6, the electricity can be removed uniformly from the no-image area B. Accordingly, deterioration and deficiency of picture quality and useless consumption of toner can be prevented.

Abstract: PURPOSE:To reduce the cost and to improve the quality by converting a composite video signal expressed with a digital value to another composite video signal expressed with an analog value. CONSTITUTION:Two color difference signals expressed with digital values and a color burst signal 29 expressed with a digital value are modulated by two chrominance subcarriers, which are different in phase and have the same frequency, to obtain two modulated color difference signals 25 expressed with digital values. Two modulated color difference signals 25 and a signal obtained by synthesizing a luminance signal expressed with a digital signal and a composite synchronizing signal consisting of horizontal and vertical synchronizing signals are digitally added to obtain a composite video signal 26 expressed with a digital value. This composite video signal 26 is converted to a composite video signal 27 expressed with an analog value. Thus, the composite video signal of high quality is obtained with a low cost.

Title: Method of forming metal thin film on surface of oxide superconductor
Inventor: SHIMAOKA KAZUHIRO
IPC: H01L39/24
Filed: 1991-01-19
Abstract: PURPOSE:To form a metal thin film as a normal conductor layer so as to be thin and homogeneous on the surface of a substrate composed of an oxide superconductor by a method wherein, when the metal thin film is formed on the surface of the substrate composed of the oxide superconductor by a vacuum vapor deposition method or a sputtering method, the temperature of the substrate and the thickness of the film are specified. CONSTITUTION:When a metal thin film is formed on the surface of an oxide superconductor substrate by, e.g. a vacuum vapor deposition method, the substrate 1 is kept within a range of 450 to 600 deg.C and a vapor-deposition speed is maintained within a range of 0.001 to 0.05nm/sec. The metal thin film is formed to be a thickness of 10 to 30nm. Since the vapor-deposition speed is slow, many crystals are grown on the surface of the substrate. Since the temperature of the substrate is high at 450 to 600 deg.C, the material for the metal thin film is moved violently on the surface of the substrate 1. The planar spread of the material for the metal thin film deposited on the surface of the substrate 1 is promoted. The metal thin film 2 which does not contain any pinhole and which is homogeneous is formed.
