Title: Thin film deposition device and manufacture of semiconductor production device
Inventor: SHINDO HISASHI
IPC: B01J19/08
Filed: 1991-12-13
Abstract: PURPOSE:To produce a thin film having no transition region without temp. change due to light irradiation during film formation by providing a movable shielding plate transmitting light containing no wave length absorbed by main and auxiliary feed gas. CONSTITUTION:A movable transparent shielding plate 109 is installed above a substrate 103 in a reactor vessel 101. High frequency voltage is applied between a high frequency electrode 105 and the reactor vessel 101 to excite auxiliary feed gas. The substrate 103 is irradiated with light on the surface side from a light source 108. The temp. of the substrate is adjusted to the prescribed one by the temp. rise due to light irradiation and a substrate heater 110. When the high frequency voltage is stabilized, the transparent shielding plate 109 is removed from above the substrate 103, starting the deposition of a SiO2 gate insulating film. Since the shielding plate 109 stops the film formation until the high frequency voltage is stabilized, the formation of a transition region during the film deposition is prevented. When a gate insulating film of a field- effect transistor is formed using this device, a good interface state is realized to improve the performance of the transistor.

Title: Brushless dc motor driving system having no rotor position detector and its driving circuit
Inventor: BIN HEIKUN
IPC: H02P6/16
Filed: 1990-11-30
Abstract: PURPOSE: To provide a function of double speed by making each-phase coil of a DC motor electrically conduct at an electrical angle of 180 degrees to increase the maximum speed of the motor. CONSTITUTION: When turned-on signals U, W are in a high-potential state and a turned-on signal V is in a low-potential state, a high-potential signal is outputted at an AND gate AND1, and when the turned-on signals U, V are in a high-potential state and the turned-on signal W is in a low-potential state, a high-potential signal is outputted at an AND gate AND2. Similarly, when the turned-on signals V, W are in a high-potential state and the turned-on signal U is in a low-potential state, a high-potential signal is outputted at an AND3. Thus, the outputs of the AND gates 1 to 3 are combined by an OR gate 1 and applied to a frequency generating signal FG. Since the signal FG is proportional to the rotational speed of a DC motor, the rotational speed of the DC motor can be detected from the signal FG.

Title: Claw device for mechanical reduction gear
Inventor: NAGAMI SATOSHI
IPC: F16D23/06
Filed: 1993-12-27
Abstract: PURPOSE:To prevent the deterioration in shift feeling by two-stage motion and the dropping out of a gear by setting the inclination of the shift-up engaging surface of at least one of a sleeve spline and a gear spline larger than the inclination of the shift-down engaging surface. CONSTITUTION:At shift-up operation, a sleeve spline 3 is first engaged and synchronized with a ring spline 7 by an operating force F. After this synchronization is completed, the sleeve spline 3 makes contact with the shorter chamfered part 31 of a gear spline 10. Since the chamfered part 31 of the gear spline 10 is set small, the chamfered part 31 of the gear spline 10 is smoothly slid to fit the sleeve spline 3 into the gear spline 10. Since the sleeve spline 3 is fitted to the gear spline 10 by making contact with the shorter chamfered part 31 of the gear spline 10 and sliding thereon, in this way, two-stage motion is never caused, and the deterioration of shift feeling is prevented.

Abstract: PURPOSE:To prevent the presence of knots in the intensity distribution of exit light by specifying the thickness or width of an optical waveguide core and the refractive index of this optical material and emitting guided light of a higher mode with the unimodal intensity distribution. CONSTITUTION:A thin film 12 of Ta2O5 is formed as the optical waveguide core on a nonlinear optical crystal substrate 11 consisting of a single crystal (a) plate of KTiOPO4 (a substrate having the face orthogonal with the a-axis of the crystal as a plate face) and patterns 13 of SiO2 are loaded thereon, by which the charge type optical waveguide is formed.
