Patent JP-S5690172-A (JP)
Title: Gas pressure adjuster
Inventor: AKIYAMA SATOO
IPC: F16K17/04
Filed: 1979-12-20
Abstract: PURPOSE: To simplify and make compact a local gas pressure controller by a construction wherein a primary side gas is made to pass through a body sliding in direct proportion to the loading pressure of a pilot in the local gas pressure controller for supplying the gas from a supply source to consumers after regulating the gas pressure.  
     CONSTITUTION: A primary side pipe and a secondary side pipe for supplying a gas are connected to a flange 4 and a flange 5 of a case 1, respectively. A supply port 19 is connected to the loading pressure outputting port of a pilot where the primary and secondary side pipes have been connected together. If the quantity of the gas used is near zero, and if the pressure on the secondary side is higher than the set value, the loading pressure becomes lower, while a sliding body 22 is deflected to the right by a spring 33. Then the right side end 23 of the sliding body comes in contact with a valve sheet 38, closing the passage between the primary and secondary sides, interrupting the gas supply from the primary side to the secondary side. In addition, since the pressure on the secondary side is lowered in proportion to the quantity used, the loading pressure is increased, moving the sliding body 22 to the left and allowing the primary side gas to be supplied to the secondary side in proportion to the secondary side pressure.

Abstract: PURPOSE: To make it possible to optically read from the segment of an optical tape, to enhance the reliability with low cost and to prepare for HDTV recording by incorporating a sealed window disposed on the surface of a housing. CONSTITUTION: A specific head is designed so as to bring the optical tape into contact with an optical head rotating without separating from the head by a window (e.g. window part 15). As for VISTATAPE cartridge, the design for the tape is substantially the same as for the head in contact with the tape except the following two points. First, a laser beam 18 must pass another optical interface and the part 15. Second, a long distance is between the head and a recording layer 22. This long distance is according to the mechanical clearance necessary for the head to conform to the inside of the opening 11.

Filed: 1980-11-25
Abstract: PURPOSE:To suppress the expansion due to diffraction of a surface wave beam, by forming an apodized electrode and a normal electrode on the surface of a piezoelectric substrate and connecting both electrodes by a dot surface wave guide path. CONSTITUTION:An apodized electrode 21 and a normal electrode 22 are formed on the surface of a piezoelectric substrate, and a dot surface wave guide path 23 is formed between both electrodes with a metallic vapor-deposition film. An electrode 31 is formed with crossing finger electrodes where the cross width is different in positions, and a wave guide path 32 is formed with many dot metallic films. Metallic dots are arranged irregularly in the propagation direction of surface waves and are arranged in the direction orthogonal to the propagation direction with a constant distribution, namely, metallic dots are distributed most densely in a center 33 of the propagation axis of surface waves and are distributed more thinly according as going from the propagation axis. Thus, the expansion due to diffraction of the surface wave beam is suppressed without damaging amplitude and phase characteristics of the energized surface wave beam.

Title: Amorphous silicon solar cell of high weather-resistance
Inventor: FUJITA NOBUHIKO
IPC: H01L31/06
Filed: 1984-08-09
Abstract: PURPOSE:To markedly improve the weather resistance of solar cells by a method wherein the thickness of a P type or N type a-Si layer on the light incidence side is increased to approx. 500-2,000Angstrom . CONSTITUTION:A clear electrode 2 and a lead-out electrode 6 are formed on a glass substrate 1. Next, a P type a-Si 3 and then an I-type a-Si 4 are stacked in glow discharge at 300 deg.C or less with the mixture of BH6 in SiH4, and an N type a-Si 5 is stacked by using PH3 with SiH4; then, an Al electrode 7 is adhered. At this time, the P-layer 3 on the light incidence side is selected thicker than coventional: 500-2,000Angstrom , and the I-layer 4 is formed to approx. 5,000Angstrom , and the N-layer 5 to approx. 500Angstrom . This construction inhibits short wavelength light from reaching the active region, i.e. I-layer 4 by thicknenning the P-layer 3 and enables the apprearance of the local state of having levels in a forbiddend band, thus preventing the decrease in output due to the capture of once generating electron-hole pairs. Besides, selecting the thickness to 500-2,000Angstrom  can markedly improve the weather resistance while the decrease in output due to the over yield of photo absorption is prevented. The laminating order of N-I-P is also available.
