Filed: 1984-08-27
Abstract: PURPOSE:To improve the accuracy of operation or durability by providing a conical section at a part where either a communicating shaft or a operating shaft contacts the other in such a manner as to deminish in the diameter toward the other. CONSTITUTION:The upper end of a communicating shaft 15 is formed into a hemispherical cone 15b and the lower end of an operating shaft 11 into a larger hemispherical dent 11a than the cone 15b so that they can contact each other. As a float 23 floats abbuting against the lower end of the communicating shaft 15 to press down the top surface of a cover member 8 against the force of a spring 16 and a buoyancy of the float 23, the operating shaft 11 and the communicating shaft 15 move down being guided by guide sections 10 and 13 respectively. As the float 23 is pressed down with the communicating shaft 15 and a magnet 24 fixed at the lower end thereof gets in contact with the bottom of a reservior main section 4, a magnetic flux of the magnet 24 acts on a reed switch 28. This enables the setting almost at the center of the contact point while automatic centering and also minimizes the transmission of a rotary force.

Abstract: An approx. 35 micrometre thick electrolytically precipitated copper foil is used as carrier with a strongly structured surface profile on one side. On this structured surface is applied a 100 micrometre thick layer of an organic UV-hardenable polymer as an insulation layer. The lined foil is then laminated to the surface of a fibreglass epoxy laminate which is provided with a connection pattern of copper. Lamination occurs under pressure and heat between flat plates, and with the polymer layer turned towards the connection pattern, but before lamination the space between the plates is evacuated. - Then the copper foil is removed by etching, and the polymer layer is dried at low heat, and illuminated with ultra-violet light through a mask so that only parts which are required to remain are lit and hardened. The non-hardened parts are dissolved away using a solvent which does not attack the hardened parts. In this way, the underlying connection pattern contact points have the apertures leading to them disclosed. Chemical and electrolytic metalling is effected so that all surfaces of the insulation layer and apertures are lined with a copper layer approx. 100 micrometres thick.

Abstract: In a pneumatic reciprocating actuator of the kind comprising a cylinder which defines a forward-motion chamber and a return-motion chamber, and a piston which is reciprocal in the cylinder and separates the forward-motion chamber and the return-motion chamber, a start stroke forwardly is initiated by admission of gaseous operating fluid from an inlet port in to the foreword-motion chamber with both the forward-motion chamber and the return-motion chamber initially at zero pressure. The operating fluid is also passed from the inlet port into the return-motion chamber during the start stroke until a back pressure of a predetermined magnitude has been produced in the return-motion chamber. Then the return-motion chamber is automatically closed by a pressure control valve unit, whereby the return-motion chamber will form a cushioning chamber for cushioning the movement of the piston in the forward direction, thereby preventing piston over speeding during the start stroke.
