Abstract: PURPOSE:To prevent the intrusion of saline water into the upper chamber of a diaphragm and prevent the trouble of a switch due to the saline water by keeping the upper chamber of the diaphragm at atmospheric pressure by installing a porous film which permits the passing of gas only in the air vent hole in the upper chamber of the diaphragm. CONSTITUTION:A diaphragm 9 is installed on the outlet side of a filter 8, and an air vent hole 12 is formed on the upper chamber 11 of the diaphragm, and a switch 10 is installed on the diaphragm. When a negative pressure is generated on the outlet side of the oil filter, the switch 10 is connected by the diaphragm 9, and the clogging of the filter is informed. In this case, a porous film 13 which pemits the passing of gas only is installed in the air vent hole in the upper chamber of the diaphragm. Accordingly, sufficient aspiration through the porous film 13 is enabled by using the air vent hole 12 in a rather larger size, and the upper chamber 11 can be kept at the atmospheric pressure. While, the intrusion of saline water is prevented by the porous film 13, and the trouble of the switch 10 can be prevented.

Abstract: PURPOSE:To make it possible to surely set thermosetting resin even when thickness of an impregnated foam is thicker by a method wherein the press molding of the thermosetting resin impregnated foam is done with a top force and a bottom force under the state that hot air is kept penetrating through the foam. CONSTITUTION:A hollow top force 3 and a hollow bottom force 4 are respectively provided onto a top ram 1 and onto a bottom ram 2. Holes 7 for hot air, which are provided on the pressing faces of the top force 3 and of the bottom force 4, are bored so as to be staggered on the top force 3 and on the bottom force 4. A thermosetting resin impregnated foam 5 (hereinafter referred to as the impregnated foam) is set between the top force 3 and the bottom force 4. By changing over a three way valve 14 at the start of the pressing of the impregnated foam, the hot air, the temperature of which is raised, is passed through a filter 10 and fed through an outlet port 8 to the space of the top force 3 and simultaneously a valve 13 is opened. The fed hot air enters from the holes 7 for hot air of the top force 3 in the impregnated foam 5 and raises the temperature of the thermosetting resin and finally flows out of the holes 7 for hot air of the bottom force 4. Thus, the thermosetting resin reacts efficiently and sets and at the same time the thermosetting resin of the whole sheet sets uniformly.

Filed: 1989-03-27
Abstract: PURPOSE:To match impedances and to increase the optical switching ratio of an electrooptical medium and further to increase the margin of production by adopting the structure in which a photoconductor is enclosed by an insulator. CONSTITUTION:RPC when dark is extremely high and RISO, RLC are high and, therefore, the most of the impedance of an equiv. circuit is governed by an electric capacity. The partial pressure of the liquid crystal of the external impressed voltage when dark is, therefore, decreased by enclosing the photoconductor 102 with the insulator 101. The ratio of the voltages impressed on the liquid crystal at the dark time and at the time of photoirradiation is, therefore, increased and the extinction ratio of the electrooptic effect is taken large. Further, the voltage leak of the dark time is suppressed by the increase in RPC and the holding performance is improved. The easier matching of the impedances is executed in this way and the optical switching ratio of the electrooptical medium is increased.
