Title: Selective oxidation and isolation
Inventor: KUDO NOBORU
IPC: H01L21/318
Filed: 1987-09-11
Abstract: PURPOSE:To suppress the redistribution of a well region and to improve the integration of an integrated circuit by selectively forming an oxide film with an optical nitride film formed on a semiconductor substrate used as a mask, thereby forming the nitride film having a sufficient thickness at a low temperature or in a short time. CONSTITUTION:With an optical nitride film 3 formed on a semiconductor substrate as a mask an oxide film 6 is selectively formed. For example, the substrate 1 is heated by an infrared ray lamp in an ammonia gas atmosphere, thereby forming the optical nitride film 3 having 50-200Angstrom  of thickness on the substrate 1, a well 2. Then, an oxide film 4 having 200-1000Angstrom  of thickness is formed by a CVD method, and a nitride film 5 is further formed by a CVD method to have 200-2000Angstrom  of thickness. Then, with a resist pattern so formed as to remain on an element region as a mask, the films 5, 4, 3 are etched by dry etching or the like, and the resist is removed. Thereafter, a region not masked by the film 3 on the substrate 1 is oxidized by thermally oxidizing at 1000-1100 deg.C, and a field oxide film 6 is formed.

Title: Electrooptic device using tft array
Inventor: SUZUKI HIROSHI
IPC: G02F1/133
Filed: 1987-09-11
Abstract: PURPOSE:To prevent an abnormal voltage from being applied to the holding capacitor of a current stage and to improve the display quality by applying a gate pulse to the gate line of the current stage after a time constant determined by at least the resistance and capacity of the gate line of the last stage. CONSTITUTION:The current stage gate pulse 11 is applied to the current stage gate line 3 after time is elapsed by the time constant tau determined by the capacity of the last-stage gate line 2. Thus, the TFT array is driven to write a signal in the holding capacitor 5 by the TFT 7 on the current-stage gate line 3 in an area where variation in the transient variation of the last-stage gate line 3 is sufficiently small. Consequently, an abnormal voltage is prevented from being applied to the holding capacitor 5 to improve the display quality.

Title: Apparatus for arranging tape cassette
Inventor: MORITA TSUGIO
IPC: B65B35/30
Filed: 1989-09-05
Abstract: PURPOSE:To automate arrangement and transfer of tape cassettes onto a tray by a method wherein when the number of the transferred tape cassettes reaches a specific value, a side of the tape cassettes is pushed so that the tape cassettes arranged on a widthwise direction on a carrying means are pushed onto a tray which has been sent out by a tray sending means. CONSTITUTION:Every time a tape cassette A is transferred onto a belt 7, a supporting plate 11 moves so that an interval between a label face on a direction opposite to movement of the belt 7 of the tape cassette A and a guide plate 8 is constant. When the number of detected tape cassettes A by a photo sensor reaches a specific value, a fork 14 is lowered by a cylinder 15. When the number of the tape cassettes thus transferred onto the belt 7 reaches a specific value and interposed between the supporting plate 11 and the fork 14, a cylinder 28 operates to allow a pushing plate 29 to push a side of the arranged tape cassettes A on the belt 7 toward a tray B on a roller conveyer 24, so that the cassettes A are passed over a guide plate 27 to be transferred onto a bottom late of the tray B. Thus operation is automated.

IPC: G06F3/023
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To give real feeling as if an object is operated to a user by controlling the fluid resistance of electric viscous fluid, which is generated by the movement of an object in an outer member incorporating tubes filled with electric viscous fluid. SOLUTION: An outer member 2 into which the hand of a user is inserted is formed on a soft material and a plurality of tubes 6 filled with electric viscous fluid 5 are incorporated. The respective tubes 6 are closely closed at finger tip side end parts 6A and opposite side end parts 6b are connected to a storage tank 8. When the user inserts a wrist 14 into the outer member 2 and flexes the finger tip 15, the tubes 6 fitted to the outer member 2 are bent, the inner volume changes and the fluid 5 flows. When an electric field generation means 9 interrupts the flow of the fluid 5, the movement of the fluid 5 is restricted and the flexing movement of the finer tip 15, which changes the inner volume of the tube, is prevented. Thus, the intensity of an electric field on the electric viscous fluid 5 is changed and therefore various feelings can be given to the finger tip 15 of the user.

Abstract: PURPOSE:To prevent the speed of a vehicle from being reduced during the releasing time of an automatic clutch so as to provide preferable driving performance by controlling the clutch so as to vary the clutch engaging speed according to the load on the vehicle when the gear is shifted. CONSTITUTION:An accumulator 6 and a solenoid supply valve 7 are closed normally but opened at the releasing time of a clutch. A solenoid discharge valve 8a is opened normally and once electrified, is closed with a clearance for a flow course remained according to the control signal which is issued on the basis of the compensating speed. The solenoid discharge valve 8b is so constituted that the valve opening area thereof is wider than that of the solenoid valve 8a and is closed normally but opened when electrified. The quantity per a unit time of pressure oil which is discharged from an oil pressure chamber 32 of an actuator 3 when the solenoid discharge valve 8b is opened is greater in comparison with that when the solenoid dischage valve 8a is opened. Since the engaging speed of the clutch 2 becomes high, it may be regulated by selectively actuating either the solenoid discharge valve 8a or 8b.
