Title: Magnetic inspecting method
Inventor: HIRAKAWA KIYOSHI
IPC: G01N27/84
Filed: 1979-06-28
Abstract: PURPOSE: To make it possible to detect even a small flaw, by detecting leakage magnetic flux by the use of a specific magnetic inspecting agent.  
     CONSTITUTION: Grains of a magnetic substance having 50W1,000Å grain size are mixed into a liquid such as oil and water to obtain a colloidal magnetic inspecting agent to be used. Then, this magnetic inspecting agent is applied on a body to be checked, which is magnetized to 100W5,000 gauss by using an electromagnetic coil, etc., while attension is paid to the size of magnetic-substance grains of the magnetic inspecting agent, thereby checking the state of aggregation of magnetic grains of the magnetic inspecting agent in the magnetization state. Consequently, the magnitude of leakage magnetic flux leaking through a defect part such as a cracking flaw is detected being increased more than conventional one, and even an extremely- small cracking flaw of 2W10μm can be detected.

Title: Closing-controlled valve with control chamber
Inventor: JIYATSUKU FURUNIEERU
IPC: F16K31/122
Filed: 1992-04-02
Abstract: PURPOSE: To control close finish speed in pressurization of a control chamber by providing a first piston working in association with a fixed valve seat to block a duct; a second piston on which a control fluid works; a hole closed when the two pistons are in contact; and a spring disposed between the two pistons. CONSTITUTION: In an opening stage, only a first piston 50 is opened under a high pressure, and a narrow flowing cross section of a through channel 62 of a second piston 56 is opened. The second piston 56 keeps on moving until the hydrocarbon flowing cross section is wholly opened. When a pressure of a control chamber 38 rises, the second piston 56 becomes in contact with a valve seat 19, while the first piston 50 is not in touch with the second piston 56 in a first stage, and high-pressure hydrocarbon continuously flows through the through channel 62. The first piston 50 is in contact with the second piston 56 in a sealing state, and complete close of a valve is an instantaneous action. Consequently, the close of the valve is controlled to avoid generation of a reduced pressure in an outlet duct 18.

Title: Decoding circuit
Inventor: MURATA YUKIO
IPC: H03M5/12
Filed: 1987-04-03
Abstract: PURPOSE:To execute the error processing at decoding in a real time by using a shift means to shift a coded data one by one bit each at the occurrence of an error in a decoding circuit receiving the coded data together with a line synchronizing signal and decoding them in a real time and releasing an error signal by a line synchronizing code in the coded data. CONSTITUTION:If an error takes place, a flip-flop 107 is set and an error signal 28 goes to a high level. An output of an OR circuit 29 to a shift control circuit 24 remains at a high level. Thus, the data inputted from a storage device to a shift circuit 22 is shifted one by one bit each, the result is outputted as a code data 31. Thus, in case of an MH code, an EOL code is detected and in case of an MR code, an (EOL+1) code is detected. In case of detecting the EOL code or the like being the line synchronizing code, the compression code in succession to the line synchronizing code is taken correct and the decoding processing from the preceding line is restarted. Thus, even with an error taken place, normal decoding processing is restarted regardless of the decoding error of the preceding line.

Abstract: PROBLEM TO BE SOLVED: To produce a liquid crystal panel which deals with the trend toward higher fineness and larger area and to maintain the uniform orientation of liquid crystals of this liquid crystal panel. SOLUTION: A glass substrate 11 packed with resins 13L between metallic electrodes 12,... is pressurized in an arrow F1 direction via a smoothing plate 32 and the resins 13L are cured in this pressurized state. An elastic film 31b is formed on the surface of this smoothing plate 31 and, therefore, the resin film 32b intrudes between the electrode spacings and forms recesses of a prescribed depth in the films 13L. The similar stage is thereafter repeated by using not the smoothing plate 32 with the elastic film but the smoothing plate which is not coated with the elastic film. As a result, the resins 13L are packed into the recesses and are cured and the smooth surface is formed by the resins 13L and the metallic electrodes 12,....  If the liquid crystal panel is produced by forming transparent electrodes, etc., on this smooth surface, the delay of the voltage waveforms is eliminated by combination use of the metallic electrodes 12,... and the transparent electrodes and the liquid crystal panel dealing the trend toward the higher fineness and the larger area is obtd. In addition, the liquid crystal layer thickness is made uniform and the orientation state of the liquid crystals is improved.
