IPC: G03G21/00
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To obtain an electrophotographic photoreceptor evaluating device, which is suitable for a photoreceptor for a digital system copying machine and a printer and capable of evaluating a characteristic value by using high-luminance LEDs and allowing several ones to simultaneously emit light, so as to obtain the exposure light source of high-luminance and short-time pulse. SOLUTION: In the evaluating device for evaluating the characteristic of the electrophotographic photoreceptor, with its electrification and exposure, the exposure light source of the evaluating device consists of two or more LEDs 1 simultaneously emitting the light and the light by a pulse modulated signal is emitted to attain exposure. The LEDs 1 are of high-luminance LEDs and it is preferable that ones whose luminous intensity is >=1000 mcd are used. On the other hand, driving is attained in such a manner that a driving current is fixed for a rated current, to keep an exposure wavelength constant. At this time, control for exposure intensity is adjusted in such a manner that a filter 3 or a diaphragm is installed between the LEDs 1 and a sample 8. Then, two or more high-luminance LEDs 1 simultaneously emit the light, to obtain high-luminance light by the pulse modulated signal.  Thus, accurate beam shaping and a complex scanning optical system required for scanning exposure with a laser beam are dispensed with.

Filed: 1990-07-20
Abstract: PURPOSE:To minimize the time of continuing inspection with equipment for zero-phase component input remaining disconnected by detecting a disconnection in the equipment in keeping with the detection of a ground fault accident. CONSTITUTION:Calculation is performed to determine a zero-phase voltage as given when an accident desired to detect occurs with a ground electrostatic capacitance set to a maximum estimated value for a transformer for an earth type instrument connected to a bus and a zero-phase current as given when a complete ground fault accident occurs with the ground electrostatic capacitance set to a minimum estimated value for a zero-phase current transformer connected to circuits separately. When a ground fault is detected, a zero-phase (hereinafter, referred to correction zero-phase) voltage is below the calculated zero-phase voltage with a residual component corrected to be calculated from an output of the transformer for the earth type instrument and when a maximum correction zero-phase current of the zero-phase current transformer is above the calculated zero-phase current, a disconnection detection signal is generated. This enables the detection of a disconnection in the transformer for the earth type instrument when at least a complete ground fault occurs.

Title: Refrigerant distributor, refrigerant distributing mechanism and air conditioner
Inventor: UMEDA TOMOMI
IPC: F25B41/00
Filed: 1994-08-18
Abstract: PURPOSE: To provide a refrigerant distributor for an air conditioner, Wherein the vapor-liquid two-phase flow of a refrigerant flowing into the refrigerant distributor through a flow-in pipe is distributed to a plurality of flow-out pipes as the refrigerant flow having generally uniform dryness, the pressure pulsation of the vapor-liquid two-phase flow is suppressed, and the vibration of pipes and the flowing noises of the refrigerant are reduced. CONSTITUTION: In a refrigerant distributor 1, an impingement wall 4 perpendicular to an axial line of a flow-in pipe 2 is formed, and a plurality of flow-out pipes 3 are radially connected to the flow-in pipe 2 in a state orthogonal to the axial line thereof. The vapor-liquid two-phase flow of a refrigerant flowing into the refrigerant distributor 1 through the flow-in pipe 2 impinges against the flat impingement wall 4 of the refrigerant distributor 1 to change its flowing direction at 90 deg., whereby the mixing of a vapor phase with a liquid phase is accelerated to be converted into a sufficiently vapor/liquid-mixed state and to be distributed to the plurality of flow-out pipes 3 as a uniform refrigerant. A maximum distribution performance can be obtained when the axis of the flow-in pipe 2 is aligned with the direction of gravity.  By this method, a refrigerant distributor can be set even in a narrow space by arbitrarily varying the mounting angles of the flow-out pipes 3.
