Title: Electrostatic charging mechanism for electrophotographing type printer
Inventor: WATANABE AKIO
IPC: G03G15/02
Filed: 1987-04-28
Abstract: PURPOSE:To always reduce the variance of the surface potential of an OPC drum and to improve the quality of an image by boosting the output voltage of an electrostatic charger only in a 1st rotation of the OPC drum. CONSTITUTION:A voltage generated from a high voltage generator 8 is boosted when a resistance value between a point A and the earth is small, and since the resistance value is almost zero, the initial rotation of the photosensitive drum (OPC drum) 3 impressed a high voltage to the charger 9 as shown by B in a figure (a). When a time 4 is controlled so as to output a high level in a 2nd rotation and after, a transistor(TR) 6 is turned off by a signal obtained through an inverter 5 and a resistor 7 is inserted between the point A and the earth. Thereby, a high-voltage generator 8 impresses voltage on the charger 9 as shown by C in the figure (a). Consequently, the surface potential of the drum 3 is fixed independently of the rotation of the OPC drum 3 as shown in a figure (b).

Title: Liquid level measuring instrument
Inventor: KOBAYAKAWA KOICHI
IPC: G01F23/22
Filed: 1986-05-09
Abstract: PURPOSE:To facilitate data processing for calculating a liquid level by arranging plural thermometers vertically at specific intervals nearby the liquid level and at the side wall part of a tank which contains liquid having a temperature gradient, and computing mean temperature normalized on the basis of measured values. CONSTITUTION:The respective thermometers 31-3n are arranged vertically in a section of temperature variation at almost equal intervals so that even if the liquid level fluctuates, the thermometer 31 is in vapor phase and the thermometer 3n is in liquid phase without fail. Consequently, the temperature at the point of 3n increases monotonously as the liquid level rises and there is a constant function relation between the liquid level and mean temperature. The relation between the mean temperature and liquid level is constant regardless of the absolute value between the vapor phase and liquid phase, the mean temperature normalized by the equation of normalized mean temperature = (mean temperature-vapor phase temperature)/(liquid phase temperature-vapor phase temperature) is computed, and the liquid level in the constant function relation is found on the basis of said computation result.

Abstract: PURPOSE:To correct a measuring error by fetching only the same polarized component of two lights, making it interfere, also fetching a part before the interference, and measuring an intensity of the polarized component utilized for the interference. CONSTITUTION:A right turn light and a left turn light which have been emitted from a fiber 2 reach a half mirror H.M.1 and are synthesized, but before that time, a part of them is reflected by half mirrors H.M.2, H.M.3. Subsequently, before the lights are made incident to photodetectors 42 and 43, a polarizer 32 and 33 are inserted, so that a polarized component of the same direction as a polarizer 31 in front of a photodetector 41 passes through. In this case, outputs of the photodetectors 42 and 43 become Er<2> and El<2>, respectively. That is to say, a variation state of a polarizing direction being in the course of propagation through an optical fiber is observed by photodetectors 32, 33 added newly. In this way, a problem of a measuring error due to a variation of the polarizing direction is solved.
