Title: Hollow yarn type ultrafilter membrane module
Inventor: AZUMA TATSUO
IPC: B01D63/02
Filed: 1987-05-26
Abstract: PURPOSE:To rapidly return to raw water when water intake is started by filling the liq. stagnation part in the title module with an adhesive to reduce the amt. of the water with decreased purity accumulated in the module when water intake is stopped. CONSTITUTION:A raw water inlet nozzle 11 is provided on the side of a housing, a permeated water nozzle 12 is furnished on the housing, and the adhesive 18 is filled to eliminate the stagnation part of raw water to prepare the hollow yarn-type ultrafilter membrane module. The module is used as the ultrapure water filter at the point of use. The raw water is introduced from the inlet nozzle 11, permeated through a hollow yarn 17 from the outside to the inside, and discharged from the permeated water nozzle 12. Since the adhesive 18 is thus filled, the water entering from the inlet hardly stagnates and is discharged from the outlet. Accordingly, the resistivity and TOC are recovered rapidly to normal at the time of water intake starting after the water intake is stopped.

Filed: 1981-08-20
Abstract: PURPOSE:To obtain a semiconductor device in which elements are isolated without decreasing the performance of the elements by providing an insulating layer containing charge for depleting the other conductive type impurity region of low density on the surface of an element isolating region. CONSTITUTION:An isolated p type region 28 and a thick insulating film 29 formed on the surface of the region 28 are formed.

Title: Controller for ac electric railcar
Inventor: YANAGISAWA KATSUHIRO
IPC: B60L3/00
Filed: 1992-05-22
Abstract: PURPOSE:To alleviate influence of a voltage phase of an AC trolley wire by variably setting a reference current value for judging whether the current of a secondary winding is an overcurrent or not based on the voltage phase of the wire. CONSTITUTION:A power synchronizing signal forming circuit 14 forms a signal having the same phase as that of the voltage of an AC trolley wire 1. A reference current value having the same phase as that of the voltage of the wire l is set according to the signal by a reference current value setter 11A. Currents of secondary windings 3a, 3b detected by an AC current detector 9 are compared with the reference current value by a comparator 12. In this case, when the current detected by the detector 9 exceeds the reference value, the comparator 12 outputs an overcurrent detection signal, thereby stopping operations of pulse- width modulation control converters 4, 5 and a variable voltage variable frequency inverter 7. Thus, influence of the voltage phase of the wire 1 can be alleviated.

Filed: 1990-05-21
Abstract: PURPOSE:To accurately control an output from a driving side by forming a means which clamps and fixes the external fitting part of a displacement-direction converting means to a shaft by using a material which is lower in coefficient of heat expansion than the displacement-direction converting means. CONSTITUTION:Expansible bodies 5a and 5b of the torque sensor 5 of the device are formed of synthetic resin and a driving shaft 1, a driven shaft 2, and clamping nut 12 and 20 are formed of iron which is lower in coefficient of heat expansion than the expansible bodies 5a and 5b. The shaft mount parts 9 and 17 of the expansible bodies 5a and 5b which expand at high temperature more than the driving shaft 1 and driven shaft 2 are pressed by the clamping nuts 12 and 20, so that the expansible bodies 5a and 5b have no play on both the shafts 1 and 2. If the temperature drops in this state, the inner peripheral surfaces of the expansible bodies 5a and 5b only press the outer peripheral surfaces of the fitting parts 10 and 18 of the driving shaft 1 and driven shaft 2 respectively. Then the shaft mount parts 9 and 17 of the expansible bodies 5a and 5b are fixed and held on the driving shaft 1 and driven shaft 2. The sensor 5 has no play on both the shafts 1 and 2 regardless of temperature variation and the output is accurately controlled from the driving shaft.

IPC: G01C17/28
Filed: 1986-06-05
Abstract: PURPOSE:To prevent the end of one rotation from being misdecided during the swiveling operation of a moving body by finding an accurate error from an azimuth vector whose output value difference is smaller than a set value between two detected directional component outputs, and correcting the output of an azimuth detecting device. CONSTITUTION:The azimuth detecting device whose position relation with the moving body is fixed relatively detects the azimuth of terrestrial magnetism as two divided orthogonal components to find the azimuth of the moving body. The detecting device detects one-side azimuth vectors V11 and V12 and other-side azimuth vectors V21 and V22 equal to intersections of a circle or ellipse formed by the azimuth vector tracks of the two directional components and straight lines parallel to a Y axis and when the output value of X is nearly equal to the vectors V11 and V22, an error arithmetic means finds the mean Y output values of them to find the Y-axial distance between an origin O and the center Oe of the ellipse, i.e. error Ye. Then, a correcting means subtracts the error Ye from one component output value Y of the azimuth detecting device on the basis of the error Ye of one component obviated by the error arithmetic means to make a correction.
