Filed: 1984-10-31
Abstract: PURPOSE:To generate a stable clock signal with a desired pulse width by providing a delay circuit from which a signal with different delay time is extracted, a logical circuit and a selector circuit. CONSTITUTION:When a clock is given from a CLKIN to a delay circuit 1, clock signals with different delay are obtained from points DL0-DL2.

Title: Vehicle movement state amount estimating device
Inventor: ITO TAKESHI
IPC: B62D6/00
Filed: 1985-10-17
Abstract: PURPOSE:To provide a vehicle movement state estimating device which also determines a movement state amount, being difficult in actual measurement, and has function equal to those of plural single movement state amount sensing device, by a method wherein, from actual measurements of the steering angle of a steering handle and a car speed, plural vehicle movement state amounts are estimated. CONSTITUTION:From a vehicle model previously set by a movement state amount estimating means 103, a movement state amount responding to a steering angle thetas and a car speed V is estimated. This determines a necessary movement state amount through estimation where occasion demands, and permits determination of a movement state amount being difficult in actual measurement. Thus, an estimating means 103 produces the same effect as that produced by mounting of plural sensing devices for a single movement state amount. In order to improve the estimated value of a movement state amount or control precision at an estimated value, the actual value of a single movement state amount is detected by an actual valve detecting means 102 to feedback it to correct the vehicle factors of the estimating means 103. When right and left turn movements are alternately executed, the vehicle factors are corrected only when comparing results during two types of movement produced by a comparing means 105 are coincided with each other. This coincides movement characteristic during right and left turn with each other, and enables prevention of unstabilization of vehicle movement.

Abstract: PURPOSE:To eliminate the adverse effect on a living body due to a dissociating cathode current and to enhance operability by supplying a current to respective electrodes at the time of the non-emission of a microwave and permitting the emission of a microwave corresponding to the detection result of the impedance thereof. CONSTITUTION:A control part 20 operates a constant current circuit 11 in response to the turning-ON of a fit switch and a change-over device 2 is changed over to the constant current circuit 11 to allow a current of a constant level to flow between electrodes 5, 6.

Title: Element isolating method for semiconductor device
Inventor: YAMAZAKI KOUJI
IPC: H01L21/762
Filed: 1983-12-06
Abstract: PURPOSE:To enable formation with a narrow and deep isolation width and with a small number of crystal defects by a method wherein an amorphous oxide film is grown on a thermal oxide film formed at the groove bottom of a single crystal Si substrate by the selective growing method, thus filling the groove. CONSTITUTION:A polycrystalline Si film 102 and an Si nitride film 103 are successively formed on the single crystal Si substrate 101. Next, grooves 104 and 105 for element isolation with different widths are formed, and thermal oxide films 106 are formed on the surfaces of the grooves 104 and 105. After removal of the film 103, a polycrystalline Si film 107 is formed. Then, the film 107 is etched only in the section of the film thickness. The amorphous Si oxide film 108 is formed on the film 106 at the groove bottom at a substrate temperature of 200 deg.C by the selective growing method. The element isolation region is formed by removing the part above the substrate 101. This element isolating method allows no growth of the film 108 on the surface of the film 107 on the groove side surface, but allows its growth on the film 106 at the groove bottom; therefore, grooves on the same substrate with the same depth inspite of different widths can be filled. Besides, the oxide film does not laterally grow because of low temperature growth.
