Filed: 1979-02-21
Abstract: PURPOSE: To prevent leakage of liquid from a tank by constituting a pump so that the liquid level in a large vessel lowers when the pump is operated and liquid is flowed out by syphon effect and that when the liquid level reaches a small hole part in the air introducing passage which is in alignment with a single aperture formed in the pump part, air flows in and stops the syphon action.  
     CONSTITUTION: Wheh liquid is dispensed from a polyethylene vessel having the capacity of, for example, 20l to a container having the capacity of, for example, 5l  or more by means of a pump, the liquid level in the vessel which conforms the  height in a suction pipe 4 is confirmed in the state of the suction pipe 4 inserted  completely into the large vessel, and the small hole 11 of the pump part A is  aligned with the air introducing passage 9 having a first lower small hole 12a or the  subsequent small hole 12b. Accordingly, when the pump is operated, and the liquid  level in the large vessel lowers as a result of the flowing-out of liquid due to syphon  effect, and reaches the position of the small hole 10 on the air introducing passage 9  which is aligned with the only one small hole 11 in the pump part A, then, air  flows into and the syphon effect stops automatically, and the leakage of liquid from  the tank is prevented.

Title: Simultaneous forming and inside coating method of metal
Inventor: TAGASHIRA TAMOTSU
IPC: B21D22/10
Filed: 1983-02-15
Abstract: PURPOSE:To perform welding simultaneously with forming and to simplify its working process by inserting a metallic hollow body into a die, injecting a molten metal to be coated into the metallic hollow body and pressurizing. CONSTITUTION:A metallic hollow body 1 serving as a material to be worked is inserted into a die 3. A molten metal to be coated is injected in the metallic hollow body 1 and pressurized when it is in a semimolten state. This pressurizing can be made by a mechanical pressure using a pressurizing rod, etc. or by a gas pressure such as compressed gas etc. The hollow body 1 is bulged out along the die 3 by this internal pressure and formed. At this time, an activated newly formed face generated at the inside of the hollow body 1 does not come into contact with air but comes directly into contact with the molten metal. At the same time, it is brought into close contact by pressure and deposition is accelerated. Accordingly, welding can be effected without requiring any pretreatment to remove an oxide film on the surface as was formely the case.

Filed: 1983-02-15
Abstract: PURPOSE:To increase gain and operating margin by using an amplifier where a logical threshold voltage is variable in an amplifier such as CMOS inverter, and controlling automatically a logical threshold value to bring it to the vicinity of a reference voltage. CONSTITUTION:When the logical threshold value of a simulating amplifier A1 and a main amplifier A0 is at a potential higher than a reference voltage VR1 in the initial state, an output signal O1 of the simulating amplifier A1 goes to a level higher than a reference voltage VR2 and an output signal O2 goes to a negative potential. Thus, the potential of a control signal Vc1 is shifted negatively by a control signal generating circuit G1. The logical threshold value of the simulating amplifier A1 and the main amplifier A0 is shifted to a low potential by this control signal Vc1. When the reference voltage VR1 and the logical threshold value are made equal after a series of operations continue, the potential of the output signal O1 and the reference voltage VR2 is made equal and when the potential of the outut signal O2 is reduced to zero V, the control signal Vc1 is held.
