Title: Zero phase current detecting device using magneto-optical element
Inventor: TAKAHASHI GENJI
IPC: G01R29/16
Filed: 1986-06-26
Abstract: PURPOSE:To share a sensor having magneto-optical effect with an optical current transformer too for phase current detection by detecting the current flowing in each phase by the use of an optical current sensor utilizing a magneto-optical effect and finding the sum of each detecting value. CONSTITUTION:Light generated from a light source 24 is conducted to a polarizer 18 by means of an optical fiber 26 to be made incident on a detector 16 as straight polarized light at an polarizing angle of 45 deg., then a plane of polarization rotates due to the magnetic field induced by the current flowing in a conductor 10 when said light passes through the detector 16. The polarized light which is made incident on a detector 20 is inputted to a receiver 28 through an optical fiber 30 and a voltage proportional to a phase current of each phase is outputted from an operational amplifier part 29 to an output terminal (a) of the optical CT. The voltage outputted to a terminal (b) of the zero phase output is inputted to a computing element 31, thus the zero phase current I0 is outputted by each phase current found from the inputted voltage.

Title: Low voltage buffer amplifier for fast sample-and-hold circuit
Inventor: NAGARAJ KRISHNASWAMY
IPC: H03F3/50
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To prevent harmonic distortion due to the modulation of a tail current and to improve an upper margin necessary to the operation of a source follower transistor by providing a differential pair having a bias circuit, a load connected to one of a 1st pair, a level shifter connected to the other of the 1st pair, etc. SOLUTION: A capacitor C1 is provided in series with a line connecting the connection point of the drain terminals of 1st stage transistors M2 and M3 and the gate of a source follower transistor M7. When the capacitor C1 is charged, a direct current voltage from the 1st stage to the source follower stage rises. Then, the modulation performed in an input tail current by an input signal is reflected in the drain current of the transistor M3. Thus, the distortion due to the modulation of the tail current is cancelled. Also, the gate voltage of the source follower M7 becomes close to the supply voltage, the output voltage of the 1st stage becomes sufficiently low and M2 and M3 becomes operable in a saturation area. Thus, the upper margin of the transistor M7 is improved.

Title: Optimum control of heat collecting system
Inventor: KURIYAMA TAKAFUMI
IPC: F28F27/02
Filed: 1981-09-24
Abstract: PURPOSE:To make it possible to follow a circumstantial change sufficiently by a method wherein only the direction of change and the change itself of each of operation variables toward an  optimum operating point of the titled system are determined by a computer and the precedure  of setting a process input toward the determined direction is repeated to make the optimum  operating point reached. CONSTITUTION:A controller H reads in measured values regarding the flow rate, the temperature or the like of each of the sections of the heat collecting system and judges whether or  not the amount of the collection has reached an optimum value. For example, when the variation of the amount of heat collection goes below a predetermined value, the controller H  judges the optimum value has been reached. On the other hand, when the optimum value is  not reached, each of the operation variables is changed in different directions by unit amount  and the amount of heat collection at that time is calculated as sensitivity. Then a set of main  operation variables giving rise to the maximum value of the sensitivity is determined and a  set of auxiliary operation variables is selected by estimating the amount of variations of each  of the variables so as to change the variables by a predetermined amount. Thus, when the optimum amount of heat collection comes near the optimum value and becomes constant, the same operation is performed repreatedly. Accordingly, the program size can be made small  and the time required for calculation can be shortened to thereby enable the heat collecting  system to be controlled speedily.

The data for imparting tolerance to every picture element is set in the memory 26 in advance.

Abstract: PURPOSE:To prevent etching breaking generated by plasma in the partition wall of a plasma generating section and in the vicinity of the microwave transmitting window of a gas introducing pipe and the leakage of air by setting up a film wall coated with an aluminum film to a section opposite to the microwave propagating section of the plasma generating section. CONSTITUTION:A decompression chamber decompressed up to fixed pressure of 1.0Torr is partitioned by a microwave shielding plate 22, and CF4 and O2 are introduced to the plasma generating section 23 side at fixed ratios. On the other hand, microwaves of 2.45GHz generated by the oscillation of a magnetron 25 are propagated in a wave guide 26 and transmit the partition wall 27, and induce plasma in the plasma generating section 23, and the active seeds of a plasma gas generated are introduced to an etching sectin 24, and etch polycrystalline silicon on a sample and a photo-resist film, etc. The etching of the surface of the partition wall 27 is prevented by using a quartz partition wall 27 in which the aluminum layer 28 consisting of not more than 1mum film thickness is formed to the surface 27a of the partition wall because the surface reacts with the radicals of the active particles and is etched. A section around the microwave transmitting window of the gas introducing pipe can also be coated.

Title: Flow-rate measuring method by using semiconductor sensor
Inventor: TANAKA SUKEYOSHI
IPC: G01F1/69
Filed: 1983-08-22
Abstract: PURPOSE:To measure flow rates and average flow speed highly accurately, without disturbing the flow of a fluid to be measured, by arranging a semiconductor flow rate sensor and a temperature detecting sensor on the wall of a pipe. CONSTITUTION:A base voltage V6 of a heating power transistor Q3 is controlled, and a collector current ic3 is adjusted. Then the temperature of a chip 51 is increased. At this time, since the temperature of a transistor Q1 becomes the same as that of a transistor Q2, emitter-base voltages VBE1 and VBE2 become the same, emitter currents iE1 and iE2 become the same, and ic1 and ic2 become the same. When there is no flow, the output becomes zero. When a fluid flows along a carrier plate, a temperature boundary layer is formed. The temperature difference yielded between Q1 and Q2 gives effect on the emitter-base voltages VBE1 and VBE2 of the temperature checking transistors Q1 and Q2. With the change in iE1 and iE2, difference occurs between ic1 and ic2, and finally difference occurs between V01 and V02.

Abstract: PURPOSE:To grasp working conditions accurately without influencing the working efficiency by connecting an electromagnetic coil which is provided on an upper nozzle for attraction of a product to a flow meter, and thereby detecting a current flow between a wire electrode under operation and a workpiece. CONSTITUTION:By inserting a switch 9 into the side of a flow meter 11 for application of a pulse voltage between a wire electrode 1 and a workpiece 10, discharge is generated therebetween, and thereby the workpiece 10 is worked with the discharged energy.

The induction current is measured by a flow meter 11 so that the current flowing therein is detected. When the induction current indicates an abnormal value, it is understood that for example short-circuit is generated therebetween.
