Abstract: PURPOSE:To obtain a high withstand voltage IG-FET by covering the peripheral surface of the drain region formed in the IG-FET with a thin oxide film and forming an inversion layer on the surface layer of the substrate at the periphery of the region when applying a voltage to the gate electrode. CONSTITUTION:A thick field SiO2 film 22 is formed on the periphery of a P type Si substrate 21 with a P<+> type channel-cut region 23 ad an underlayer, and N<+> type source and drain regions 24 and 25 are diffused in the substrate 21 surrounded thereby. Subsequently, a thin first gate SiO2 film 26 is covered on the surface of the substrate 21 exposed between the regions 24 and 25, and the second gate SiO2 film 27 is extended onto the film 22 thereon. Thereafter, the film 27 is perforated with a window on the region 25, and is mounted on the region 25 while extending the polycrystalline Si film 28 operating also as the gate electrode and the drain electrode on the film 27. When high voltage is applied to the film 28, an inversion layer is formed in the surface layer of the substrate 21 on the periphery of the region 25, and thereby preventing the region from contacting the region 23 directly.

IPC: G01M99/00
Filed: 1980-11-13
Abstract: PURPOSE:To measure torsional oscillation precisely, by providing a rotation detector to only one end of a rotary shaft to be measured. CONSTITUTION:At the crank pulley part 1c of an internal combustion engine 1, a rotation detector 3 is provided, and the output signal A1 of the detector 3 is supplied to a phase synchronizing circuit 6. A phase comparator 6a in the circuit 6 inputs the signal A1 and a signal A4 from a voltage control signal oscillator 6c, and its output is a phase difference output A2. An LPF6 inputs the signal A2 and outputs a signal A3; high-frequency components of the signals A1 and A4 are eliminated to output the signal which has a frequency component which is the difference between the signals A1 and A4. A voltage-controlled oscillator 6c inputs the signal A3 to output the signal A4, and oscillates at a frequency relating to the voltage of the signal A3. An HPF7 removes the DC components of the signal A3, and an integral network 8 integrates the output A7. For torsional oscillation, integration is performed while attention to only the variation of an angular speed is paid, thereby obtaining a voltage proportional to the variation.

Title: Method for controlling degree of dispersion of photographic emulsion
Inventor: ISOZUMI FUMIYOSHI
IPC: G03C1/005
Filed: 1983-09-02
Abstract: PURPOSE:To make the quality of an emulsion, especially the concn. uniform when the degree of desalting of the emulsion is regulated, by controlling the degree of dispersion of a coagulated and precipitated emulsion in washing water or a solvent so as to keep the degree of desalting of the emulsion constant after finishing desalting. CONSTITUTION:In a stage for desalting a photographic emulsion by batchwise coagulation and precipitation, the emulsion is coagulated and precipitated in a reaction vessel, and after discharging the supernatant, washing water for washing the emulsion or a solvent for preserving the emulsion in a set state is added. At this time, the degree of dispersion of the precipitated emulsion in the washing water or the solvent is controlled in accordance with the silver potential or the electric conductivity. For example, the degree of dispersion of the precipitated emulsion is controlled in accordance with the EAg value detected with an EAg value detector 8 placed in the reaction vessel 2. When the amount of an undispersed emulsion is judged to be zero by this controlling method, the liq. in the bessel 2 can be handled as a uniform system. The EAg value of the liq. is then detected with the detector 8, and the amount of washing water 6 or setting gel 7 to be fed is regulated with a flow rate control valve 10 in accordance with the value of a regulator 9 so as to attain the desired degree of desalting.
