Title: Hot wire type flow meter
Inventor: TSUNEOKA YUTAKA
IPC: G01F1/696
Filed: 1983-11-08
Abstract: PURPOSE:To measure an accurate flow rate even when the temperature compensating resistance of a hot wire type flow meter varies with temperature owing to heat conduction from a support part by detecting the temperature of a fluid passage wall on which the hot wire type flow meter is supported fixedly, and correcting a measured flow rate value on the basis of the detected temperature. CONSTITUTION:The hot wire type flow meter 16 is interposed in a passage 15 which by-passes a main suction path 12. Then, a temperature sensor 22 which detects the temperature of a body 21 on which this flow meter 16 is supported is fixed to the body 21. The terminal voltage Us across this fixed resistance 2 is digitized through A-D converters 23 and 24 together with the output of the temperature sensor 22 and inputted to a controller consisting of, for example, a microcomputer. This controller 25 also inputs an engine rotating speed, cooling water temperature, etc., to determine the width of fuel injection pulses on the basis of the input signals.

Abstract: PURPOSE:To select the resolution of a slave pattern of a master-slave two-screen display television receiver by synthesizing a slave screen signal from a demodulation means onto a master screen signal so as to display two master- slave screens. CONSTITUTION:The television receiver is provided with an A/D converter means 2 sampling a signal of a slave screen with a sampling signal having a different frequency and converting it into a digital signal, and a memory 32 storing a digital signal with a different sampling frequency from the A/D converter means 2, and also a demodulation means reading the information of the slave screen from the memory means 32 in matching with the timing of the master screen and demodulating it and a control means 35 generating a control signal to select a signal whose sampling frequency differs in response to an external instruction representing whether the mode is the multi-gradation display mode or the high resolution display mode. Then the slave screen signal from the demodulation means is synthesized onto the master screen signal to display the master-slave two-screens. Thus, the resolution or gradation of the slave screen is selected with simple circuit configuration.

Title: Structure of down sprue in metallic pattern casting machine
Inventor: KURASHIMA YOSHIKATSU
IPC: B22C9/06
Filed: 1986-09-04
Abstract: PURPOSE:To obtain casting product having stable quality by adjusting reduction or expansion of runner area at lower part of down sprue by an adjusting mechanism to supply pure molten metal into a cavity. CONSTITUTION:The cavity 10 is formed by approaching the upper die 3 and each pattern 4, 5 to the lower die 2 by extending working rods 6-8 and at the same time, the adjusting mechanism 14 is reduced and a sleeve 12 is descended to a position, where a lower moving regulating body 14b collides with a stopper 14a. Next, at the time of supplying the molten metal into a pouring cut 13, as the lower part 11a of down sprue 11 is reduced, the staying time of molten metal in the down sprue 11 is delayed, and so the impurities, such as gas and slag, etc., mixed or generated into the molten metal, floats up to the upper side of down sprue 11. Further, the massive solid impurities are hindered at small gap part of the lower part 11a, to pour the pure molten metal into the cavity. In this way, the pure molten metal is supplied into the cavity and the casting product having stable quality is obtd.

Title: Electrostatic charge measuring method
Inventor: TAKAHASHI SHIGERU
IPC: G01R29/12
Filed: 1994-09-01
Abstract: PURPOSE: To enable quantity of electrostatic charge on a semiconductor device, etc., to be measured precisely by always maintaining the distance between an object to be measured and a measuring probe constant before measuring it. CONSTITUTION: A container 12 is installed, with a guide pin 11 provided on a base plate 10 serving as a guide. An X-axial shaft 14 and a Y-axial shaft 15 are arranged thereon, so that a measuring probe 13 moves horizontally thereon, and the quantity of electrostatic charge of an object to be measured 16 stored in the container 12, is measured. In other words, a measured value is read by gripping a handling knob 17 and moving the measuring probe 13 on the object to be measured 16. Thereby, the dispersion of the measured values due to distance variation is restricted, since a distance between the measuring probe 13 and the object to be measured 16 is always constant. In addition, any individual error due to each of measurers is reduced.  Further, since the measuring probe 13 does not come into contact with the object to be measured 16, the measuring probe 13 or the object to be measured 16 is not damaged.

Title: Working method for superconducting thin film
Inventor: ISHIBASHI KENZO
IPC: H01B13/00
Filed: 1987-08-24
Abstract: PURPOSE:To obtain a superconducting device composed of fine pattern, by projecting a spot formed by converging a laser light or an electron beam on a part of ceramic system superconductor thin film baked on an electrically insulative substrate of high thermal conductivity, and turning the part selectively into a non-superconducting structure. CONSTITUTION:A fine spot 4a of laser light 4 is formed on a superconducting thin film, which is scanned. When the light intensity of the light beam 4 is increased, the temperature of the part of superconducting thin film irradiated with the light spot 4a locally rises at several thousands degree, so that perovskite structure is destroyed, and the part is turned into a non- superconducting region. Since a device applying the superconducting thin film is used while a current is made to flow, the conductivity of a substrate 2 is made as small as possible. It is preferable to use a ceramics system substrate like SiC whose thermal expansion coefficient almost coincides with that of the superconducting thin film.

Abstract: PURPOSE:To implement the low potential of a reset drain voltage, by applying clock pulse voltages, which are lower than clock pulses for transfer gate electrodes on the upstream side in the transfer direction, to a plurality of transfer gate electrodes immediately before an output gate electrode. CONSTITUTION:A plurality of transfer gates phi1 and phi2 are alternately arranged on a P-type substrate 1. The transfer gate phi1 and phi2 comprise upper gates phi1A and phi2A and lower gates phi1B and phi2B. Transfer gates phi3 and phi4 are arranged immediately before an output gate electrode OG and have the same structure as the transfer gates phi1 and phi2. Clock pulses phiH1 and phiH3 in the same phase are imparted to the transfer gate electrodes phi1 and phi3. Clock pulses phiH2 and phiH4 having the reverse phase with respect to phiH1 and phiH3 are imparted to the transfer gate electrodes phi2 and phi4. The clock pulse phiH4 varies in the range of -2V-8V, and phiH3 varies in the range of -4V-6V. Therefore, the channel potentials (c) directly beneath lower gate electrodes phi4B and phi3B vary in the ranges of about 10.5V-18V and 9V-16.5V. The channel potential of a reset drain electrode VRD becomes lower than the conventional value by 4V.
