Title: Leak inspecting device for gas pipeline
Inventor: IKADA TAKAOMI
IPC: G08B21/18
Filed: 1995-03-31
Abstract: PURPOSE: To provide the leak inspecting device for gas pipeline with which the presence/absence of fine leak at large capacity gas pipeline can be inspected without erroneously discriminating it as the presence of fine leak because of supplied pressure fluctuation, etc. CONSTITUTION: After cutting, a flow rate detecting means 15 measures the flow rate of gas flowing through a gas bypass 11a parallel with gas pipeline 11 cut by a cutting means 13. Based on the measured flow rate of gas, a fine leak detecting means 27a-1 detects the presence/absence of fine leak. When a back flow detecting means 15c detects that a double phase type flow rate pulse to be generated by sensors 15b1 and 15b2 is generated by back gas flow, the flow rate detecting means stops measuring the flow rate of gas. Minimum value storage means 27c41 -27c49 collect and store the minimum value of gas flow rate measured on one day for the several days as many as periodical life patterns. Corresponding to the change pattern of the stored minimum value, the fine leak detecting means detects the presence/absence of fine leak.

Title: Array substrate, and liquid crystal display device and its driving method
Inventor: HANARI ATSUSHI
IPC: G09G3/36
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To obtain the array substrate which has low power consumption and is free of an overload on an IC and short in write time by providing a means which applies a voltage below a video signal voltage before the video signal voltage is applied to a video signal line. SOLUTION: The potential of the signal line 10 after reaching a reference potential Va with a switch 22 ON rises up to a given data signal potential with the switch 22 OFF and a switch 12 ON. After the switch 12 is turned off, the potential is held and a gate signal is applied to given pixel to write the signal to the specific pixel. This operation is performed normally in every horizontal cycle. Consequently, the reference potential Va is written before the signal is written to the signal line 10 from a data bus line 14, so even when the write is performed with a maximum amplitude, the voltage amplitude in the write may be small. Therefore, a driving IC having drive performance, which is smaller than that of a conventional one, can be used and the power consumption is reducible.

Title: Thin film magnetic head for vertical magnetic recording
Inventor: OSHIKI MITSUMASA
IPC: G11B5/31
Filed: 1978-06-23
Abstract: PURPOSE:To improve a recording density characteristic by separating a conductor coil from the magnetic pole back edge to reduce the influence of the coil magnetic field. CONSTITUTION:Conductor coil 4 is formed on substrate 1, and magnetic pole 2 is formed on coil 4 through insulating layer 3. Substrate 1 of chip 5 which is formed in this manner is caused to adhere to slider 6. Then, conductor coil 4 is positioned forward for the running direction  of medium 7, and magnetic pole 2 is positioned backward for it; and the interval between back edge 2', which approaches medium 7 most and magnetizes medium 7 in the vertical direction, of magnetic pole 2 and conductor coil 4 becomes wide when slider 6 floats up. Therefore, since the influence of the magnetic field of conductor coil 4 is reduced when conductor 7 is magnetized by magnetic pole back edge 2', a recording density at a vertical magnetic recording time can be improved without lowering a write efficiency.

Title: Adaptive array antenna system
Inventor: ITO KIYOHIKO
IPC: H04B7/10
Filed: 1988-03-31
Abstract: PURPOSE:To always obtain a multipath fading reducing effect with the title system by making a reference signal synchronous to the multipath component having the maximum incident power at a high speed. CONSTITUTION:LMS(Least Mean Square) parallel antenna operations are performed based on the referring signals r1-r3 of plural sequences having time lags and the output of the signal processing section whose error signal power becomes the minimum among the signal processing section 2a-2c operating in parallel with each other. Since the referring signal supplied to the selected signal processing section is always synchronous to the multipath component having the maximum power, the referring signal becomes synchronous to the multipath component at a high speed. Therefore, a good multipath fading reducing effect can be obtained even under a multipath fading environment associated with abrupt changes.

Abstract: PROBLEM TO BE SOLVED: To control the flow of the slag into a nozzle by providing a solenoid coil capable of applying the AC current to a periphery of a molten metal nozzle, and detecting the start of the flow of the slag into the nozzle by the change in the impedance. SOLUTION: A solenoid coil 3 capable of applying the AC current of 5,000 A.turn-100,000A.turn is arranged in the periphery of a molten metal nozzle 10. The AC current with 100-1000Hz in frequency and with <=5000A.turn, e.g. 3-300A.turn flows to detect the start of the flow of the slag into the nozzle 10 by the change in the impedance of the solenoid coil 3.
