Filed: 1987-04-15
Abstract: PURPOSE:To prevent photosensitive drums from positionally deviating in a main- scanning direction to overlay image resists on the photosensitive drums with high accuracy, by a method wherein, an optical output determined according to a latent image potential which is set on the plural photosensitive drums is detected, and the writing timing of a laser beam emitted from each laser unit is adjusted. CONSTITUTION:Within a blanking period t2, a semiconductor laser 3 is always turned ON, and the back beam of the semiconductor laser 3 is detected by a photo diode 2. According to the detected value, a reference potential VREF1 is inputted to one end of a comparator 1. On the other hand, when a laser beam LB is inputted to a light-receiving element 52, a light-detection signal B1 based on the emitting power is inputted to the other end of the comparator 1. Then, the waveform of the light- detection signal B1 is shaped by the reference potential VREF1. The comparator 1 outputs a horizontal synchronizing signal BD to be of an image writing timing when the light-detection signal B1 is lowered to less than the reference potential VREF1. With a reference potential VREF2, a light-detection signal B2 is also changed similarly and the waveform of the light-detection signal B2 is shaped by the reference potential VREF2, and the horizontal synchronizing signal BD is not changed.

Title: Production of superconductive material
Inventor: HIRANO SHINICHI
IPC: C04B35/45
Filed: 1987-04-15
Abstract: PURPOSE:To produce easily a superconductive material having a fixed compsn. and having no dispersion of the characteristics by molding fine powder obtd. by hydrolyzing a mixed solution of metal alkoxides of several constituting materials and drying the hydrolyzed product to a desired shape, then sintering the molded product. CONSTITUTION:Metal alkoxides (e.g. isopropoxide) of constituting elements of an aimed superconductive material, for example, Y, Ba, Cu, etc. are charged to a solvent (e.g. isopropyl alcohol) in a proportion necessary for resulting a specified ratio of numbers of atoms (e.g. Y:Ba:Cu=1:2:3 by mol%). The metal alkoxides are hydrolyzed by heating at, for example, 50-90 deg.C while dropping water into the mixture under stirring. After separating the hydrolyzed product by filtration, it is dried at 100 deg.C in gaseous N2 to obtain thus fine powder of 50-200Angstrom  particle size [e.g. fine powder having a compsn. expressed by Y:Ba:Cu: O=1:2:3:6-9 (oxygen defect)]. The fine powder is then crushed after calcining at about 500 deg.C and molded to a desired shape (e.g. fine wire, thin film) under pressure, and sintered at about 900 deg.C for about 8hr in the air to obtain thus R-(Sr, Ba)-Cu-O type superconductive material having perovskite structure (wherein R is at least one kind of element selected from Y, Sc, and lanthanoids).

Title: Temperature-sensitive non-powered automatic valve unit
Inventor: YOSHIDA TOORU
IPC: A01G25/16
Filed: 1983-05-23
Abstract: PURPOSE:To automatically open or close a valve depending on the temperature, by connecting the opening and closing of a prescribed-temperature-operated valve unit to that of a shutoff valve unit. CONSTITUTION:The heightened primary temperature Pa of a chamber (a) is transmitted to another chamber (b) so that the pressure Pb of the chamber (b) becomes equal to that Pa of the chamber (a). Since the pressure Pc of still another chamber (c) is zero at that time, the open/close valve 2 of a main valve unit is pushed to remain closed. When the outside air temperature has become lower than a set level, the thermostat of a prescribed-temperature-operated valve unit 6 acts to open a valve 61 so that pressurized water starts flowing along the valve. As a result, the water pressure Pb becomes lower than that Pa. Because of this pressure difference, the valve 2 of the main valve unit is lifted so that water flows from the chamber (a) into the chamber (c).

Abstract: PURPOSE:To improve the stability of a transmission frequency by detecting the fluctuation of the frequency when it is transmitted and by compensating the fluctuation at the stage of processing a reception signal. CONSTITUTION:A directional coupler 11 takes out a part of a transmission signal. This signal is converted into a signal in an IF band by a mixer 12 and a  phase difference between the latter and the COHO signal of a COHO oscillator  1 is detected by a phase detector 13.
