Title: Pressure sensor
Inventor: MIYAHARA IKUYA
IPC: G01L19/14
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a pressure sensor which can securely obtain radio wave shield effect, accelerate miniaturization, and facilitate assembling operation. SOLUTION: On a circuit board 33 which closes a metallic case 31, a radio wave shield layer is formed of conductor layers 331 and 333. Consequently, the circuit board 33 is only provided to obtain radio wave shield effect and the case 31 need not be fitted with a lid member with a through capacitor. Thus, a lid member like this is unnecessary and the length of a terminal provided in the circuit board 33 can be made short irrelevantly to the through capacitor, so the pressure sensor can be more miniaturized. Further, the through capacitor is not necessary, so troublesome operation such as soldering can be eliminated to facilitate the assembling operation.

Title: Method for continuously discharging molten glass at constant rate and apparatus therefor
Inventor: ITO HIROSHI
IPC: C03B7/082
Filed: 1990-01-26
Abstract: PURPOSE:To enable continuous discharge of molten glass with an extremely small dispersion in outflow rate by pressurizing molten glass, discharging the molten glass through an orifice and controlling the pressure to a positive pressure synchronously with controlling of the pressure to a negative pressure. CONSTITUTION:A lid 4 is in a hermetically closed state and a solenoid valve 15 is simultaneously closed. The second piston 6 is in a fixed state to advance the first piston 10 to a prescribed extent. Since a glass melting tank 1 is in a hermetically sealed state, the pressure applied to molten glass 2 by the advance of the first piston 10 mostly acts as function to discharge the molten glass through an orifice 7. Thereby, the molten glass 2 in a volume corresponding to the extent of advance determined by the regulating position of a stopper 61 can be discharged from the orifice 7. The first piston 10 is then retreated to the original prescribed position and the second piston 6 is advanced by control of a controller 25 synchronously with the aforementioned operation so as to provide a volume equal to that corresponding to the extent of retreat by the first piston 10. The solenoid valve 15 is subsequently opened to retreat the second piston 6 to the original prescribed position. The solenoid valve 15 is then closed to complete a series of operations of the aforementioned apparatus.

Title: Gyroscope
Inventor: HAYASHI SHUNJI
IPC: F16C32/04
Filed: 1988-01-28
Abstract: PURPOSE:To reduce a reduction in the power for turning a top with a higher accuracy, by making one of a rotating shaft and a rotating shaft support thereof of superconductor and the other thereof of magnet. CONSTITUTION:When a nitrogen gas below the critical temperature of superconductors 16 and 18 is supplied into a cooling container, the superconductors 16 and 18 are made superconductive. At this point, a repulsive force acts by a Meissner effect between supports 22 and 24 and the superconductors 16 and 18 to support a top 12 keeping a rotating shaft 14 from contacting the supports 22 and 24. As a result, the top 12 rotates at a high speed free from action of a friction force on the rotating shaft 14 thereby eliminating errors due to friction. This achieves a higher accuracy of a gyroscope while reducing a power for rotating the top 12.
