Title: Fuel feeding port
Inventor: MOTOHASHI TOSHIAKI
IPC: B65D90/10
Filed: 1990-09-06
Abstract: PURPOSE:To make it possible to prevent fuel leakage caused by a guide ring from happening by a method wherein a distance from the upper surface of a packing to the lower edge of a guide ring is made larger than a distance from the upper surface of a fastening part to a step part. CONSTITUTION:A flange part 51 of a guide ring 50 is pinched between the lower end of a coil spring 30 and a packing 29. A cylinder 52 which extends in a fuel feeding pipe 2 is formed into a tapered cylindrical shape of which the diameter becomes smaller toward the lower end. A distance X from the upper surface of the packing 29 to the lower edge of the guide ring 50 is larger than a distance Y from the upper surface of a fastening part 15 of a main body 11 to a sealing part, i.e., a step 12, and the title fuel feeding port is formed to satisfy, e.g., an equation, X-Y=10mm. Therefore, the cylinder part 52 of the guide ring 50 is hard to get on the step 12. But, when the lower edge of the cylinder 52 gets on the step 12, the upper edge of the packing 29 protrudes from the upper surface of the fastening part 15 of the main body 11. Therefore, fuel feeding by connecting a coupling at the tip of a fuel feeding hose cannot be performed.

Abstract: PURPOSE:To reduce an error in quantization during integration by making the light emission frequency or duty ratio of a light emitting means for distance measurement different before and after a point of time which is a specific time after the start of light emission. CONSTITUTION:A counter 1004 outputs an H signal to a terminal OUT with a clock signal CLK and the signal of an inverter E 1006 through an AND circuit 1005 a specific time t1 after the signal CLK falls to L. The output of the counter 1004 is inputted to an AND circuit 1003 through an inverter 1016 during the period from the start of light emission to the output of a count (out) from the counter 1004, and the same output signal as a signal SYNC2 is inputted to an AND circuit 1002 until the output of a comparator 1013 is inputted to an AND circuit 1003. When the count (out) rises to H, the signal from an AND circuit 1001 is inputted to an AND circuit 1002, whose output SYNC3 allows the output of a signal SYNC2' up to t1 and then allows the output of a signal synchronizing with SYNC1, thereby reducing an error in quantization during integration.

Abstract: PURPOSE: To enable a packing operation accompanied by no danger on health by blowing powder into a rear wall by a gaseous medium to fill the powder, then packing the powder by the higher-pressure gaseous medium, and by evacuating through a filter element during the filling and the packing. CONSTITUTION: This method for filling powder in a wall of a refrigerator cabinet body is as follows. First, all amount of the powder necessary for heat insulation of the cabinet body is supplied to a container 40 through a valve 48. Next, pumps 28, 50 are started, and valves 32, 44 are opened, while a valve 52 is opened such that a pressure in the container 40 becomes a higher pressure (an excessive pressure) than an ambient air pressure by about 0.5 bar. The powder is fed by flowing air from the pump 50 to the direction of the vacuum pump 28. At that time, a filter element 24 stops the powder to fill the powder in spaces 26, 36 of the cabinet body, while the vacuum pump 28 evacuates and exhausts the air. In time of the filling, a valve 56 is occasionally opened for supplying the pressurized air from the pump 50 so as to press the powder.  Then, a piston 38 presses the powder to pack the powder still more.
