Title: Gas mixing detection monitor
Inventor: OUEN RUTSUSERU SUNATSUTOJIYAA
IPC: H02K9/08
Filed: 1990-11-19
Abstract: PURPOSE: To detect the leakage of a small amount of hydrogen by arranging a first pressure escape valve that is set to a larger second given level than a first given level and a second pressure relief valve that is set to a larger given level than the second given level in a liquid circulation state within a receiving tank. CONSTITUTION: When the pressure of a hydrogen gas 40 that stays in a water receiving tank 37 reaches a first given level, it is discharged from a first pressure escape valve 103. As far as the amount of leakage is smaller than a given volume flow, an orifice 106 with an opening passes this flow due to the pressure drop of 6 psig and maintains pressure in the receiving tank 37 at this level. When the amount of leakage exceeds the volume flow level, the orifice 106 cannot discharge the gas 40 from the first pressure relief valve 103 quickly. As a result, a pressure in the receiving tank 37 continues to increase to a fourth specific level that is set to 6 psig, operates a pressure switch 109, and at the same time operates an alarm, thus giving an alarm to an operator that the amount of leakage is larger.

Filed: 1994-12-19
Abstract: PURPOSE: To provide an optical semiconductor device such as a light emitting diode, a semiconductor laser, a surface light emission type semiconductor laser, etc., having narrow light emitting spectral width and high light emitting efficiency. CONSTITUTION: An active layer is formed of a plurality of quantum wires QW, which has a structure having at least one adjacent wire QW in which carrier can be tunneled, the carrier generated by current injection or light exciting is sequentially tunneled to the wiring QW having relatively lower energy, a light is emitted from the wire QW having relatively low energy to obtain a light emission having narrow light emitting spectral width. The wiring can be replaced by a quantum box. Since the tunneling speed of the carrier is low at the low temperature, the light emitting spectral width is wide, but at the ambient temperature, the tunneling speed of the carrier is large, and hence the light is emitted at the wiring having low energy, and the spectral width is narrowed.

Filed: 1991-11-28
Abstract: PURPOSE:To provide the operational amplifier of CMOS configuration able to drive a low resistance output load without increasing a ratio (W/L)of a channel width W to a channel length L of an output stage MOS transistor(TR). CONSTITUTION:An input signal is differentially amplified by a differential amplifier stage 50 and its output is level-shifted by a level shift stage 60, the result is amplified by a 1st amplifier stage 70, a PMOS 91 in an output stage 90 is turned on and a current is outputted to an output terminal 93. In this case, an output of the differential amplifier stage 50 is amplified by a 2nd amplifier stage 80 and an NMOS 92 in the output stage 90 transits to the OFF state. Since the load MOS 82 in the output stage 90 has the same characteristic as that of the NMOS 92, the NMOS 92 is not completely reached to the OFF region. Thus, the crossover distortion is reduced.

Title: Heavy corrosionproof laminated steel panel
Inventor: WATANABE KEIICHI
IPC: B32B27/30
Filed: 1994-11-25
Abstract: PURPOSE: To suppress the generation of the swelling of a resin film caused by a corrosion product even when the exposed surface of a steel panel is corroded or the steel panel is corroded by a processing flaw, in a laminated steel panel wherein a resin film is laminated on the surface of the steel panel to which chemical forming treatment is applied through an adhesive, by setting the strain stress of the resin film to a specific value. CONSTITUTION: A laminated steel panel is obtained by laminating a resin film on the surface of a steel panel such as a galvanized steel panel subjected to chemical forming treatment such as chromate treatment through an adhesive. The strain stress at the time of 6% elongation at 20 deg.C of the resin film to be used is set to 9N or more per a film width of 10mm. When the strain stress at the time of elongation of the resin film is large, since the tensile force of the resin film is high, the swelling of the resin film caused by a corrosion product generated by corrosion is suppressed dynamically. The strain stress of the resin film may be adjusted by a plasticizer, for example, in the case of polyvinyl chloride and may be adjusted by the compositional ratio of monomers constituting a polymer in the case of an acrylic resin.
