Abstract: PURPOSE:To exhibit composite functions of color recording, overlaying, etc., and to obtain a sharp image, by laminating an insulating layer formed by dispersing magnetic particles and photoconductive particles into an insulating resin having a carrier transfer function on a conductive substrate. CONSTITUTION:An insulating layer (B) formed by dispersing magnetic particles 2, such as gamma-Fe2O3 doped with Co, and photoconductive particles 3, such as ZnO, into an insulating resin 1, such as polyester, having a carrier transfer function is laminated on a conductive substrate A to provide a magnetic photoreceptor P. In the case of using the layer B for an overlay, it is charged with a charging device 4 and brought into direct contact with a magnetic head 5 to write a magnetic pattern on it, thus permitting magnetic record efficiency to be raised, and the magnetic head to be made in a small size. Then, it is exposed with an exposure device 6, developed by an ordinary method, and the image obtained is transferred. After these procedures, the layer B is restored to an initial state, thus permitting once development to write in images simultaneously optically and magnetically, a small size magnetic head to be used, so a sharp image to be obtained. In addition, e.g., a black-and-red 2-color image is obtained likewise.

Title: Exposing device
Inventor: SAKADO KEIICHIROU
IPC: G03B27/72
Filed: 1983-09-28
Abstract: PURPOSE:To always obtain a constant total exposure quantity irrespective of the variation of light intensity of a light source by reducing remarkably the light intensity of the light source in the course of closing operation of a shutter so that an excessive exposure quantity portion is not generated. CONSTITUTION:A light intensity of a light source is controlled so that it attains to the first light intensity for an exposure before starting the opening operation of a shutter, and it attains to the second light intensity which is lower than the first light intensity, at least in an opening operation period of the shutter. From a time point t0 when a trigger signal for showing that the shutter is opened is supplied, the first light intensity P0 for exposure is maintained. The light intensity irradiated onto a wafer goes to large gradually following the opening operation of the shutter, and goes to constant at a time point t1 when the shutter is fully opened. Also, the exposure quantity is obtained by integrating the light intensity on the wafer, and increases slowly from the time point t0 to t1, and quickly from t1 to t2. In such a way, the total e xposure quantity goes to constant by lowering the light intensity of the light source 1 in the course of closing operation of the shutter.

Abstract: PURPOSE:To enhance the vibration suppressing characteristic of a multistage shell type tower without increasing a wt. or cost, by constituting the multistage shelf type tower by providing a large number of shelves each comprising a perforated plate to the interior thereof and arranging thin plates between the shelves. CONSTITUTION:Thin plates 7 are newly and additionally provided between shelves each consisting of a floor plate 3 and a reinforcing material 4 in a tower 1.

Title: Heater cooler
Inventor: SUGA KUNIHIRO
IPC: F25B13/00
Filed: 1989-07-11
Abstract: PURPOSE:To reduce a work amount of a compressor and to reduce a consumption power by a method wherein a check valve and a receiver are disposed on the inflow side of a refrigerant heater, a control valve for bypassing from the high pressure side of a compressor to the receiver is provided, and the control valve is intermittently opened and closed. CONSTITUTION:With a control valve 9 released, a liquefied refrigerant in a receiver 5 is pushed to a refrigerant heater 7 by means of delivery gas from a compressor 1 and through the working of a check valve 4. Since the refrigerant bypasses so as not to flow through a heat exchanger on the indoor side, power consumption of the compressor 1 is decreased by an amount equivalent to a pressure loss of a heat exchanger 3. Meanwhile, with the control valve 9 closed, a gaseous refrigerant accumulated in the receiver 5 during release of the control valve is condensed and cooled in the heat exchanger 3 to produce a liquid refrigerant, which flows in the receiver 5. Thereby, a pressure in the receiver 5 is reduced and since a force by which a refrigerant is attracted only from the direction of the heat exchanger 3 through the working of a check valve 6 is exerted, a work amount of the compressor 1 is decreased and power consumption is reduced. Further, since the control valve 9 is formed such that when a heating load is high and a heating amount is high, a ratio of an opening time is decreased and when a heating load is low and a heating amount is low, a ratio of a opening time is increased, a circulating amount of a refrigerant flowing through the heat exchanger 3 is regulatable matching with a heating load.

Title: Automatic color registering device
Inventor: HARA AKIRA
IPC: B41F33/06
Filed: 1988-07-19
Abstract: PURPOSE:To enable a positional error of a color register mark to be detected in a short recognition time and with high accuracy, by taking-in all signals through one screen in correspondence with each color by using a single high-resolution monochromatic image pickup element. CONSTITUTION:Register spots 1 on e printing surface are imaged on an image pickup plane of an image pickup element 4, which is a monochromatic single sheet element, by an image pickup lens 2. A video signal is outputted from the pickup element 4 synchronously with a signal from a synchronizing signal generator 11, and is amplified by a video signal amplifier 5. The amplified signal is sent to a spot discriminator 6, in which it is compared with a signal level set by a level setter 7, and spot positions are extracted. Synchronously with a signal from the synchronizing signal generator 11, a position comparator 8 compares the extracted spot positions with reference positions read from a reference spot position memory. When the spot positions coincide with the reference positions, it is judged that there is no misregistering of colors, whereas when the spot positions discord with the reference positions, an error signal corresponding to the difference between the two kinds of positions is outputted. An error signal amplifier 10 amplifies the error signal, and outputs the amplified signal to a blanket cylinder position-correcting means as a correction instruction signal corresponding to the positional error.
