Title: Method for stabilizing surface potential of electrophotographic photosensitive body
Inventor: NOGUCHI TERUHIKO
IPC: G03G21/00
Filed: 1991-09-20
Abstract: PURPOSE:To stabilize surface potential and to obtain stable image quality by controlling the quantity of destaticizing light in accordance with fatigue by light and the shaving of the surface by mechanical force so that the fluctuation of the surface potential caused by the fatigue and the shaving of the surface may be restrained. CONSTITUTION:In the method in which the surface potential of an electrophotographic photosensitive body is stabilized by irradiating the electrophotographic photosensitive body with the destaticizing light before an electrostatic charging stage, the quantity of the destaticizing light is controlled by considering the fatigue of the photosensitive body by the light and the recovery thereform, the shaving of an oxide film on the surface of the photosensitive body by the mechanical force and the recovery of film thickness by oxidation so that the surface potential of the photosensitive body may be constant. The control of the quantity of the destaticizing light is performed by controlling the duty ratio of a current supplied to a lamp which emits the destaticizing light based on a duty ratio table. For example, the duty ratio is increased nearly in proportion to the logarithm of stop time and decreased nearly in proportion to the logarithm of copying time, so that the photosensitive body is made in a specified fatigue state.

Abstract: PURPOSE:To make it unnecessary to set a working hole in a ceiling plate or a maintenance opening in a housing side face by taking out a humidifying unit into an interior of a room through a mounting-demounting opening from a heat exchanging room by taking away a fixing material. CONSTITUTION:At a maintenance time of a humidifying unit 21, a decorative panel 14 and a partition panel 19 are taken away and a mounting-demounting opening 12 is allowed to communicate with a heat exchanging room R1 and a heat exchanging element 20 is taken away. Then, by taking away the partition plate 22, and making the heat exchanging room R1 communicate with a humidifying room R2, through the heat exchanging room R1, the humidifying room R2 is made to communicate with the mounting-demounting opening 12. In this state, when a fixing material 27 is taken away from the mounting- demounting room 12 along the humidifying room R2, as an upper surface of a humidifying unit 21 becomes completely free, the humidifying unit 21 can be taken out from the heat exchanging room R1 through the mounting- demounting opening 12 into an interior of a room. Therefore a maintenance opening or a working hole is not required to be set at a side face of a housing 11 or in the ceiling plate.

Title: X-ray transmissive window and its manufacture
Inventor: KUMASAKA FUMIAKI
IPC: H01L21/027
Filed: 1991-09-20
Abstract: PURPOSE:To obtain an X-ray transmissive window which has high transmissivity against X rays and, at the sane time, which can withstand a pressure difference which is nearly equal to the atmospheric pressure by forming the window by bundling a prescribed number of capillaries having a prescribed internal diameter and length in parallel and uniting the capillaries to each other. CONSTITUTION:This-X-ray transmissive window 1 is constituted by bundling a plurality of capillaries 2 having a prescribed internal diameter D and length L in parallel and uniting the capillaries 2 to each other. The diameter D and length L are decided so that each capillary 2 can have a conductance at which a prescribed pressure difference can be produced between both sides of the window 1. Even when the rate of effective aperture area of the capillaries 2 is reduced to 50%, the X-ray transmissivity of the window 1 is still maintained at a high level of 0.5 and the window 1 has such a structure that can withstand a pressure difference which is nearly equal to the atmospheric pressure. Therefore, an X-ray transmissive window which can withstand a large pressure difference and has high X-ray transmissivity and, at the same time, which can reduce the rear of installation and cost of roentogenizing devices can be obtained.

Title: Dimming device
Inventor: NOMURA YASUSHI
IPC: H05B37/02
Filed: 1992-09-10
Abstract: PURPOSE:To regenerate brightness and correct the dimming level during the fade control by reversing the execution time and dimming level based on the dimming data when resuming the brightness before execution after each scene is executed. CONSTITUTION:When a regeneration button 11 is pushed, a switch data input/ output circuit 2 reads it, a main arithmetic circuit 31 calculates the dimming levels at the normal fade time based on the dimming data of individual parts and outputs the results to dimmers 7a-7n. When a stop button 12 is pushed, the circuit 31 judges whether the dimmers are under or after the fade control. In case the dimmers 7a-7n are under control, the circuit 31 temporarily stops dimming calculation and outputs the present levels to the dimmers 7a-7n. When a reverse regeneration button 13 is pushed, the circuit 31 judges the progress state of the scene, calculates the fade time of the scene and the delay time and part time of each part, calculates dimming levels via the reverse in the normal time, then outputs them to the dimmers 7a-7n. The brightness during the fade control can be repeatedly regenerated as well as that after the fade control.
