Title: Manufacture of amorphous hydride silicon thin-film transistor
Inventor: KAWAMURA SHINICHI
IPC: H01L21/31
Filed: 1992-06-01
Abstract: PURPOSE:To prevent the degradation of properties of a semiconductor layer by forming it after effects of the source gas of a gate oxide are eliminated. CONSTITUTION:The surface of a gate oxide 3 is treated in a very weak hydrogen plasma until the source gas for the gate oxide (NH3 and N2), remaining in a vacuum chamber, has no effects on the formation of a semiconductor layer 4. This maintains the surface of the gate oxide chemically active, thereby preventing defects. After the effect of the remaining gas is removed (about 10 minutes), SiH4 is introduced at 40sccm, 0.5Torr and 0.4W/cm<2> in power density to form a semiconductor layer 4 of about 3000Angstrom  on the gate oxide 3. As a result, the semiconductor layer undergoes no degradation of its properties.

IPC: B60G17/00
Filed: 1982-08-16
Abstract: PURPOSE:To automatically control damping force in accordance with the adjustment of load of a damper spring, in a vehicle damper for the rear wheel of a motorcycle, by disposing a cam mechanism between an attaching member of the damper and the damper spring so that an adjusting element in the damper is frictionally engaged with a variable orifice adjusting element. CONSTITUTION:By rotating an adjusting fixture 25 to adjust the initial load of a damper spring 22, a frictional ring 34 engaged with the adjusting fixture 25 is rotated and therefore, an adjusting ring 33 also rotates, following the rotation of the fixture 25. Since the adjusting ring 33 is engaged by a thread with the outer periphery of a second attaching member 3, the adjusting ring 33 axially moves as it rotates. This movement is accompanied by a rod 12c through a pin 33c. Thereby, a needle valve 12 is opened and closed to adjust damping force by means of working fluid passing through a center hole 6e. With this arrangement, the adjustment of damping force is automatically made in accordance with the load setting of the damper spring.
