Abstract: PURPOSE:To provide a photocoupling type semiconductor device which is so constituted as to make the outputs of respective light receiving cells uniform by taking not only distances from a light emitting device but also a whole photocoupling structure, especially the reflection from light transmitting resin, into account. CONSTITUTION:Areas of light receiving cells 2a which are placed at a center part are largest and the areas of light receiving cells 2b and 2c placed in circumferential parts are getting smaller in accordance with the distance from the center part to lower the receiving sensitivity of a direct light from a light emitting device. When a current is applied to the light emitting device and a light is generated, the light is applied to a photodetector 10 and photovoltages are generated by a plurality of the respective light receiving cells 2a, 2b and 2c. A voltage generated by one light receiving cell is, if the light receiving cell is composed of a light receiving diode, about 0.5 to 0.6 V which corresponds to a junction potential difference. If a plurality of the light receiving cells are connected in series, the junction potential difference is multiplied by the number of connected cells.

Abstract: PURPOSE:To inhibit an intrusion of a developer into a device and a splash of a developer to form a high-quality image by providing an ion take-out power source to apply an alternating electric field between a developer holding body and an ion flow modulating means. CONSTITUTION:At an ion head 6, ions are generated by a high voltage applied by a DC power source 13. The ion flow is modulated in accordance with an image signal from an image signal source 12 by an electric field applied to an ion flow control part 62 consisting of a control electrode 8 and a head shield 71. The ion flow moves toward a developer holding body 4 by receiving a force caused by an alternating electric field formed by an alternating voltage applied from an ion take-out power source 14 to form a predetermined electrostatic latent image on a thin developer layer. The thin developer layer in which the electrostatic latent image is recorded is fed to a transfer part 170 opposed to a transfer electrode 17 with the rotation of the developer holding body 4. The electrostatic latent image on the developer holding body 4 is transferred onto a recording medium 18 and thermally fixed on the recording medium 18 by a fixer 19.

Filed: 1990-10-30
Abstract: PURPOSE:To prevent spread of the skirt of photosensitizing resin thermally fused during heating by a method wherein a thermally fused microlens material is prepared according to a different in wetness produced between a part where a microlens is formed and a part where it is not formed. CONSTITUTION:When forming treatment is effected under oxygen plasma, a part 14 where photosensitizing resin is located is brought into a hydrophilic state by means of oxygen plasma 16. When hydrophilic treatment is applied on the photosensitizing resin, affinity with the photosensitizing resin is reduced. As a result, in thermally fused hydrophilic resin 13, compared with wetting of a part 15 where the photosensitizing resin is formed, wetting of a part 14 where the photosensitizing resin 13 is not formed is lowered. Namely, when the photosensitizing resin 13 is fused by heating, a spot where wetting is reduced is formed in the part of the skirt of a microlens, whereby the skirt of the thermally fused photosensitizing resin is prevented from spreading. This constitution and method provide a high-precise microlens 17.
