Title: Manufacture of field effect transistor
Inventor: MUROTANI TOSHIO
IPC: H01L21/338
Filed: 1985-02-26
Abstract: PURPOSE:To obtain a reliable FET with high production yield, by oxidizing both sides of a gate electrode directly after the formation thereof so as to form oxide films. CONSTITUTION:After a gate electrode 15a is formed, both sides thereof are oxidized to form Al oxide films 16. A GaAs oxide film formed of itself on the surface of an exposed GaAs active layer 12 is removed by means of HCl or HF so that the exposed GaAs active layer 12 is cleaned. An ohmic metal 18 is vapor deposited for providing source and drain in a similar manner with the prior art. After any excessive metal 18c and resist 17 are removed, the ohmic metal 18 is alloyed to form source and drain ohmic electrodes 13 and 14. According to this process, the Al gate 15a is not etched by the pretreatment with HCl or HF before the vapor deposition.

IPC: F04B39/00
Filed: 1986-02-21
Abstract: PURPOSE:To obtain a shaft seal device with good sealing performance, by setting successively from a blower side a labyrinth seal, gas leak part lantern ring and a seal gas lantern ring and holding a pressure difference between the both lantern rings to a fixed value. CONSTITUTION:A shaft 5 provides successively from a blower working chamber side a labyrinth seal 8, gas leak part lantern ring 9, gland packing 10, seal gas lantern ring 11 and an oil seal 12.

Title: Reflection type screen
Inventor: YUGI SHIGETAKA
IPC: G03B21/60
Filed: 1992-02-25
Abstract: PURPOSE:To decrease the tilt angle of each unit and reduce linear stripes in a projection image between units by laminating a light transmission layer on a linear Fresnel surface which has light reflecting and converging performance in one direction. CONSTITUTION:The light transmission layer 2 is laminated on the linear Fresnel surface 1 which has the light reflecting and converging performance in one direction. The refractive index of polyvinyl chloride as the material of the light transmission layer 2 constituting the reflection type screen is 1.53, so when the light transmission layer 2 is present on the linear Fresnel surface 1 as a reflecting surface, the reference spherical curvature radius of the original shape of the linear Fresnel surface can be increased by 1.53 time as compared with a case wherein the light transmission layer is absent, and the original shape of the linear Fresnel surface based upon the reference spherical surface becomes gentle. The tilt angle of a linear Fresnel unit U band becomes close to the inclination of the tangent of the original shape, so the angle becomes small. Consequently, dust becomes hard to stick on the connection surfaces of the respective units U and the linear Fresnel surface can be prevented from flawing when handled.
