Inventor: OGAWA MASASHI
IPC: G01N27/447
Filed: 1984-05-18
Abstract: PURPOSE:To strengthen the bonding of materials and to facilitate handling, by using a three-layer structure, wherein a plastic supporting body and an acrylamide water gel are bonded by a derivative of methylmethacrylate macro-monomer, as a medium material for electrophoresis. CONSTITUTION:On a plastic supporting body, e.g., polyethylene terephthalate, a derivative of methylmethacrylate macro-monomer, e.g., the compound shown by the formula, is applied as a bonding agent layer. Then, modified polyacrylamide water gel, wherein acrylamide compound, e.g., acrylamide, a bridging agent, e.g., N,N'-methl bisacrylamide, and a compound having at least one carbamoyl group as a modifying agent, e.g. urea and the like are bridged and polymerized, is bonded. Then the obtained three-layer structure is used as an electrophoresis medium material. Since bonding is performed by the compound shown by the formula, the three-layer structure has high adhesion property. Electrophoresis and dyeing can be performed with a polyacrylamide gel film (medium layer) being mounted on the supporting body.

Title: Electrically driven focal length changeover camera
Inventor: HOSHINO YASUSHI
IPC: G03B17/12
Filed: 1985-05-14
Abstract: PURPOSE:To improve the handiness of a camera by making it possible to switch focal length even when the battery voltage of the camera is blow a specified value. CONSTITUTION:When a switch S2 is switched over to a contact (b) side by the operation of a focal length switching button, a motor 35 is driven and thereby a lens system is shifted to a regular photographing position. The first step switch S1 of a release is made on and a supply voltage to a load and a reference voltage are compared by a comparator 36. When battery voltage is above a specified voltage, it advances to an influence process and if the voltage is lower than the specified value, advance is locked and the battery is exchanged. As the moving of the lens system is made irrespective of battery check, by setting a motor driving voltage less than the reference voltage of battery check, the lens can be moved even when voltage is out of prescription. Accordingly, the lens system can be housed in a camera easily even when voltage is dropped with a lens system projected from the camera.

Title: Charger part for electrophotographic device
Inventor: SUGINO YOICHIRO
IPC: G03G15/02
Filed: 1989-04-20
Abstract: PURPOSE:To prevent toner from sticking to an end block and to prevent a charger part from being stained by covering the photosensitive body side of the end block with conductive members and earthing those conductive members. CONSTITUTION:The side of the photosensitive body 11 of the end block 31 is covered with a metallic plate 35, its end block is attached to a casing 30 with screws 36 and the metallic plate 35 is earthed. For instance, if the toner is negatively electrified and a transferring and separating charger part 15 positively discharges, the end block 31 is positively electrified. But it is covered with the metallic plate 35, so that the electrostatic attraction of the end block 31 does not act on scattering toner. Therefore, the toner scattering from a developing part 14 and a cleaning part 16 is not attracted to the end block 31. Thus, toner sticking to the end block and the stain of the charger part can be prevented.

Filed: 1993-04-27
Abstract: PURPOSE:To project an optical image having no color irregularity on a screen by shifting the light reflection and transmission characteristic of a reflector or a dichroic mirror from the optimum value. CONSTITUTION:The dichroic mirrors 5 and 6 for optical separation spectrally split light from a total reflecting mirror 4 to blue, green and red band light; and are arranged at the angle of 45 degrees with respect to the optical axis of a parabolic mirror 3. A dichroic filter 7 takes out the red band light out of light transmitted through the dichroic mirror 6 and is arranged at right angle to the optical axis of the parabolic mirror 3. The light reflection characteristic of the dichroic mirror 5 is shifted by 10nm to a long wavelength side, and also the light transmission characteristic of the dichroic filter 7 is shifted by 10nm to the long wavelength side. Thus, for example, the chromaticity temperature of a projected picture projected on the screen in the case of projecting white color light is 5800 deg.K on the peripheral part of the screen and 6600 deg.K on a central part, so that the chromaticity temperature of the projected picture is high so as not to discriminate the color irregularity.
