Title: Cap tapping detector
Inventor: OGASAWARA AKINOBU
IPC: B22D2/00
Filed: 1980-06-12
Abstract: PURPOSE: To improve the quality of steel ingots, assure safe work, and perfectly automate ingot making work by surely detecting cap tapping phenomena by the use of a flame detector during casting of a capped steel.  
     CONSTITUTION: At the time of casting a capped steel into a mold, a cap 2 is placed on the top part of the mold, and the rise of the molten steel surface by bubble expansion is prevented by the cap, whereby the degradation in the quality owing to the excessive convection by the bubbles of the molten steel is prevented. In this case, the intensity ratio of the red and blue components of the flame 3 emitting from the interval between the mold 1 and the cap 2 is detected by a detecting system consisting of a flame detecting part 4, a signal processing part 9 and a deciding and processing part 13 in order to control the quality of steel ingots by detecting the time without contacting until the molten steel expands by bubbles of CO and the like and arrives at the cover 2. From the change in the detected value thereof with time, cap tapping phenomena are detected safely with high accuracy without contacting, and the degradation in the quality of the steel ingot is automatically prevented.

Title: Variable capacity type liquid piston pump
Inventor: HANDA TAKESHI
IPC: F04B1/22
Filed: 1992-02-28
Abstract: PURPOSE:To reduce pump noise regardless of the magnitude of the capacity change ratio of a cylinder chamber accompanying the change of discharge quantity in the rotating drive of a cylinder block. CONSTITUTION:Circular inlet port 23 and discharge port 24 are opened nearly in opposite positions on the sliding surface of a valve plate 22 on which one end of a cylinder block 7 is slid. A notched groove 26 formed extending from the start end 23A of the inlet port 23 to the discharge port 24 side has a small throttle part 26B and a large throttle part 26C, and the small throttle part 26B runs the pressure liquid charged in the cylinder chamber 10 to the inlet port 23 when the capacity change ratio of the cylinder chamber 10 is minimum. The large throttle part 26C runs the pressure liquid charged in the cylinder chamber 10 to the inlet port 23 since the pressure liquid can not be sufficiently run only by the small throttle part 26B when the capacity change ratio of the cylinder chamber 10 is maximum. When the opening 10A of the cylinder chamber 10 is transferred from the discharge port 24 to the inlet port 23, the internal pressure of the cylinder chamber 10 is gently lowered.

Abstract: PURPOSE:To prevent unexpected accidents such as deterioration of electrical insulation, burning and so on by providing a timer circuit for controlling the electric current application time in a stop control circuit of a driving device of a regulator for varying damping force, thereby automatically cutting off the application of electric current when a designated application time is elapsed. CONSTITUTION:A timer circuit 51 for controlling the time for applying electric current to a driving device 31 is provided in a stop control circuit 41 of the driving device 31 of a regulator 21 for varying damping force, which is disposed in a hydraulic buffer body 11.

Title: Active matrix array and method for inspecting such array
Inventor: TAKAHARA HIROSHI
IPC: G01R31/28
Filed: 1987-04-01
Abstract: PURPOSE:To permit high-speed detection of disconnection and short circuit defects in a non-contact state by providing switching elements on at least either of gate signal wires and source signal wires. CONSTITUTION:Phototransistors Pg1-Pg4 are provided on at least either of the gate signal wires and source signal wires of an active matrix array. A prescribed voltage is impressed thereto by a voltage impressing means 2 and a current detecting means 3 is connected thereto. A light beam 5 is then projected only to the phototransistor Pg1 by a photoirradiation means 4 to turn on the same. The current is not detected in the means 3 if there is a disconnection in the gate signal wire G1 and, therefore, the disconnection defect can be detected. The inspection can thus be made simply by projecting the beam on the photoswitching elements. Missing of the inspection by the defective pressurized contact of a probe with the signal wires is thus obviated.

Title: Gas detecting semiconductor device
Inventor: NOGUCHI SHIGERU
IPC: G01N27/12
Filed: 1990-03-28
Abstract: PURPOSE:To obtain a gas detecting device wherein the bonding interface is kept in a clean state and the characteritics of the elements are stabilized by manufacturing an amorphous silicon film having high electron affinity in a clean environment, bonding the film to a noble metal film, and forming a large potential barrier. CONSTITUTION:An electrode 2 is formed on an insulating substrate 1. A semiconductor film 3 is formed of amorphous silicon on the electrode 2. A noble metal film 4 is further formed on the film 3. A Schottky junction is formed without exposing the interface to atmosphere by forming the film 3 and the film 4 continuously in the vacuum state. In this way, the interface is kept in the clean state. The work function of the film 4 is decreased when gas adsorption occurs in the surface of the noble metal film 4. The height of a potential barrier is also decreased. Thus the diode characteristics of the Schottky junction are changed. Therefore, the change in current value due to the gas adsorption is measured under the state wherein a constant voltage in the forward direction is applied, and the concentration of gas can be detected.
