Filed: 1982-07-19
Abstract: PURPOSE:To simplify a mechnism, to ensure an operation and thus to enable the quick detectin of displacement, by converting the displacement of a displacement member into a change in the intensity of light of an optical fiber. CONSTITUTION:The stem 5 of a probe is displaced when the contact 13 of the stem 5 is made touch an object by the movement of a moin-body case 1. By the displacement of the stem 5 projections 17 of a pressing body 14 are made to press an optical fiber 19 of a sensing element 16 so that the fiber is deformed. When the fiber 19 is deformed, a transmitted light decreases, an output of a photoelectric transducer 22 lowers sharply, a detection signal is delivered from an operational amplifier 26, and thereby the touch of the contact with the object is detected. When the contact 13 of the stem 5 separates from the object, the stem 5 is restored to a posture in accordance with the axial line of a shank 2 by the action of a spring board 4, and the fiber 19 is restored to its original state by an actuating means 15. Since the operation requires no opening and closing of an electric contact, rapid responsiveness is obtained, and the mechanism is made free from the infiltration of dust, the abrasion and deterioration of the contact, the fault in continuity and the adverse effect of noise. Thus, the operation is ensured, and the mechanism can be simplified.

Title: Back pressure absorbing method for liquid pipeline
Inventor: KIKUCHI SHOICHI
IPC: F17D1/20
Filed: 1989-05-18
Abstract: PURPOSE:To control the generation of the serge pressure attending on a momentary change of the flowing quantity in a main pipeline at minimum by forming a part of the main pipeline into inverted U-shape, and supplying the gas to that part to shut a part of the liquid in the pipeline with the gaseous phase. CONSTITUTION:A part of a main pipeline 6 is formed into an inverted U-shape bent pipe 3, and the gas 4 such as N2 gas or the like is supplied to the bent pipe 3 through a gas supplying branch pipe 5, and the gas 4 is sealed in the bent pipe 3 to form a gaseous phase 1 to shut the liquid 2 with the gaseous phase 1. Consequently, the back pressure of the hydraulic actuation oil momentarily discharged from a servo valve 10 is absorbed by receiving the pressure cushioning action with the compression effect of the gas of the gaseous phase 1 before the serge pressure is generated, and rising of the pressure in the pipeline can be prevented. Next, at the time of application as a hydraulic return pipeline, when the bubble quantity during the hydraulic action is increased to exceed a certain value, since it is considered that a volume exceeds the bubble floating ability of an oil tank and the bubbles flow into the pump side of a hydraulic source 12 to generate the cavitation, the capacity of supplying gas is set within a range that does not exceed the bubble floating ability.
