Title: Beam scanner
Inventor: MAMA TAKASHI
IPC: G02B26/10
Filed: 1990-11-28
Abstract: PURPOSE:To prevent the color slurring at the time of transfer of development by providing plural light transparent surfaces which are disposed to face both sides of a protective case and incline in the same direction with the axial center of rotation of a deflector. CONSTITUTION:The scanning rays reflected by a reflecting surface 3 of a rotary polyhedral mirror 4 which is irradiated from laser units 6, 7 are imaged by an optical system 8 onto a photosensitive body. The scanning rays reflected by the reflection surface 3 of the rotary polyhedral mirror 4 irradiated from the laser unit 7 is imaged by an optical system 9 onto the photosensitive body. The incident light on the rotary polyhedral mirror 4 from the laser units 6, 7 and the reflected light reflected from the rotary polyhedral mirror 4 pass light transmissive surfaces 15, 16 but the detrimental light reflected by the front surfaces of the inclined light transmissive surfaces 15, 16 is directed from the normal scanning surface toward the outer side and, therefore, the generation of ghost printing is prevented. The color slurring at the time of the transfer after the development is prevented in this way.

Title: Manufacture of semiconductor device
Inventor: SATO YASUO
IPC: H01L29/49
Filed: 1992-11-13
Abstract: PURPOSE:To reduce damage to a substrate when forming the gate electrode of a MIS type transistor. CONSTITUTION:After a polycrystalline silicon thin film 3 is formed on a gate dielectric film 2, the surface of the first polycrystalline silicon thin film 3 is naturally oxidized and then a second polycrystalline silicon thin film 4 is formed on it. Then, after the second polycrystalline silicon thin film 4 is etched to the pattern of gate electrode, the first polycrystalline silicon thin film 3 at a part which is not covered with the second polycrystalline silicon thin film 4 is completely oxidized thermally. Therefore, even if the gate dielectric film 2 is extremely thin, the first polycrystalline silicon thin film 3 and a natural oxide film 9 on it contribute to etching control, thus reducing the etching damage to the substrate when forming the gate electrode.

Filed: 1990-11-28
Abstract: PURPOSE: To prevent a photoconductive belt from being damaged by constituting a developing unit so that it is axially rotated to a non-actuating position from an actuating position and it is slidably detached from a supporting device. CONSTITUTION: A bracket 80 is rotated in order to detach the developing unit 38 from a printing device and a rail 78 is axially rotated downward around the back end so as to be inclined. Then, the unit 38 is away from the belt and axially rotated to the non-actuating position. Besides, since the bracket 80 is rotated so that the rail 78 is axially rotated downward and positined by a crossing angle with respect to a horizontal surface, that means, inclined, the unit 38 is easily detached from the printing device by being slid along the rail 78. At this position, the developing rollers 40 and 42 of the unit 38 are away ram a photocoductive surface 12 by leaving a space. Thus, the photoconductive belt is prevented from being damaged.
