Filed: 1981-10-19
Abstract: PURPOSE:To prevent emission of vaporized fuel to the atmosphere, when a fuel tank is not used, by suppressing breathing action of a breather device before internal pressure of the fuel tank reaches preset pressure. CONSTITUTION:A breather port 9 is communicated to an air layer (a) formed in the upper part of a tank 1, and opened to an upper wall 1a' of the enclosed fuel tank 1, then the first breather pipe 13, communicated to the atmosphere, is connected to this breather port 9. While a relief valve R, opened to permit emission of vaporized fuel if pressure in the tank 1 exceeds a prescribed value, is interposed in a half way of the pipe 13. Then a device is constituted in such a manner that when the tank 1 is not used, breathing action is suppressed before internal pressure reaches preset pressure. In this way, the inside of the tank 1, at no use of fuel, is placed under a completely air-tight condition before reaching the set pressure to both suppress vaporization of fuel and prevent ceaseless emission of fuel to the atmosphere, and an after-process of vaporized fuel can be easily performed.

Abstract: PURPOSE:To make a molten metal flow softly into a casting mold at a temperature being as uniform as possible, by inclining an opposed wall to a molten metal inflow port side wall to a casting mold 1, by a specific angle from the bottom of a furnace, in a holding furnace for horizontal and continuous casting of cast iron connected the casting mold to the holding furnace. CONSTITUTION:An inclined angle theta against the bottom of a furnace of a downward flow preventive bed 4 constituting a wall opposed to a molten metal inflow port side wall to a casting mold 1 is set to 30-70 deg.. According to this method, when a molten metal is replenished to a holding furnace in order to perform continuous casting, descending force of the molten metal is reduced once in a sprue 5, subsequently, the descending force is completely suppressed by a downward flow preventive part 10 of the bed 4, and the molten metal flows into the casting mold 1 in the form of a laminar flow along the inclination of the bed 4. Accordingly, a low temperature part as before is not formed, and a variation of temperature becomes small. Therefore, a corner crack of continuous castings and a disturbance of oscillation are decreased remarkably.

IPC: H04B10/564
Filed: 1979-12-24
Abstract: PURPOSE: To prevent waveform distortion by connecting a nonlinear resistance element in parallel to the DC load resistance of a photodetector.  
     CONSTITUTION: Photodetector 2 converts light signal 1 from a light emitting diode into a light current, part of which is shunted to DC load resistance 4, the base of transistor 5 and nonlinear resistance element 13. As light signal 1 increases, the unipolar light current also increases. The increase in the light current containing a DC component decreases the differential resistance value of nonlinear resistance element 13 and the increased light current is shunted to nonlinear resistance 13. Therefore, the device can be designed that while transistor 5 never gets saturated, the waveform distortion can be eliminated.

Abstract: PURPOSE: To minimize the backward bias leakage by diffusing implanted aluminum at a high temperature, so as to drive the aluminum to a substantial depth in silicon, and laterally diffusing the aluminum to the lower side of a mask existing on a region where a capacitor is formed. CONSTITUTION: A mask 20 is maintained at a center portion of a hole 12 and aluminum 20 prevents directly bombarding silicon at the center portion of the hole 12.
