Abstract: PROBLEM TO BE SOLVED: To provide a process for producing a vinyl chloride polymer having a low residual monomer content, whereby unreacted vinyl chloride monomer can be removed at good efficiency from an aqueous vinyl chloride polymer dispersion obtained by emulsion polymerization or fine suspension polymerization. SOLUTION: In recovering and removing unreacted vinyl chloride monomer from an aqueous dispersion obtained by subjecting vinyl chloride or a mixture of a major amount of this monomer with comonomers to emulsion polymerization or fine suspension polymerization, a recovery equipment composed of a plurality of connected recovery apparatuses is used, and coarse polymer particles having diameters of above 10μm and contained in the aqueous dispersion are ground with a wet grinder while the aqueous dispersion is transferred from one recovery apparatus to another. According to this process, residual monomer can be effectively removed even when the monomer removal is performed under relatively mild conditions, and a vinyl chloride polymer having a low residual monomer content can be easily obtained.

Title: Method for stopping operation of permeation vaporization membrane apparatus
Inventor: MITA MASAAKI
IPC: B01D61/36
Filed: 1993-07-21
Abstract: PURPOSE:To provide a method for preventing swelling etc., of a separation membrane when the operation is stopped for a long time by drying the surface of the separation membrane by passing inert gas, which passed through a filter, through the supply side of a permeation vaporization membrane module, after raw liquid of the supply side of the module being removed when the operation is stopped. CONSTITUTION:Supply liquid is fed to the supply part of a permeation vaporization membrane module 6 from a raw liquid supply part 1 to allow liquid components to pass selectively through the module 6. The liquid is separated by passing from the permeation side by reducing the pressure with a vacuum pomp. The operation is stopped by opening a valve 17 with the vacuum pump 11 operated, opening a valve 19 while inert gas, which passed through a filter 16 from an inert gas supply source 15 is allowed to flow in the module 6, and removing the supply liquid from a liquid extraction line 20. Especially, high purity nitrogen is preferably used as the inert gas. In the stopping method, since the supply liquid is removed, the surface of the separation membrane is dried by the flow of the inert gas, and the liquid is made difficult to stick on the surface of the separation membrane even by operating under reduced pressure, thus the swelling and deterioration of the membrane are prevented. This method can also applied to inflammable liquid, since the system is not exposed to the air.

Abstract: PURPOSE:To accurately and readily manufacture a photodiode by using a photosensitive organic insulating film for an interlayer insulating film, and by forming a contact hole by making an exposure to ultraviolet rays with an amorphous silicon film pattern as a mask for self-alignment with the pattern and the hole. CONSTITUTION:A lower electrode 11 is formed by a transparent SnO2, ITO on a glass substrate 10, and an amorphous silicon film pattern 12 is formed in the prescribed shape thereon. Then, a photosensitive organic resin is coated on the entire surface, baked to form a photosensitive organic insulating film 13, and an ultraviolet ray is then exposed from the substrate 10 side.

Inventor: TAKATANI TAKUJI
IPC: F16K31/70
Filed: 1986-07-30
Abstract: PURPOSE:To make it possible to detect an abnormal temperature, by providing such an arrangement that a valve element receives an acting force by a valve closing spring in the valve opening direction, which is smaller than an acting force in the valve closing direction, and therefore the valve closing force of the valve closing spring disappears when a predetermined temperature is attained. CONSTITUTION:A valve opening spring 29 for opening a valve element 12 which opens and closes a valve hole 11 applies a valve opening force sufficiently weaker than that of a valve closing spring 13, upon the valve element 12. The valve closing spring 13 which is a coil spring made of a shape memory alloy and provided at the front end of a spring retaining member 72, is set such that when a predetermined temperature is attained, it is deformed to extinguish its spring function. Accordingly, the valve closing spring 13 is cooled down due to leakage of LNG or the like, and therefore, the valve element 12 is opened, thereby it is possible to detect an abnormal temperature so that safe operation may be expected.
