    摘要： Ultrathin membranes for separating substances are obtained by exposing shaped articles comprising a water-soluble polymer or a mixture of a water-soluble polymer and water-insoluble polymer to a plasma of a gas selected from helium, argon, nitrogen, hydrogen, oxygen, carbon monoxide, carbon dioxide, ammonia, a hydrocarbon having 1 to 10 carbon atoms, an epoxide having 2 to 10 carbon atoms, or an alkylamine, or a mixture of these substances to crosslink the surface layer, and then washing the exposed articles with water to remove the unreacted portions. The membrane exhibits outstanding performance characteristics when used in the processes for separating or concentrating substances, such as reverse osmosis, ultrafiltration, and the like.

    摘要： A thin film of less than 300 microns in thickness can be obtained by crosslinking a surfactant with plasma or radiation. This thin film is as high in strength as an ordinary plastic film, and is usable as a substance-separating film, a substance-protecting film or an insulating film.

    摘要： A polarized relay with an electromagnetic drive comprises an electromagnetic yoke composed of a core wound with a coil and a yoke body, and having one end portion of one magnetic polarity and a pair of bifurcated end portions of the other magnetic polarity opposite to the one magnetic polarity. The bifurcated end portions are separated in opposition from each other. The one end portion of the yoke is disposed between the bifurcated end portions so as to cooperate to form a pair of working gaps. A movable block of a substantially C-like configuration incorporating a permanent magnet has two magnetic pole pieces which are disposed within the working gaps, respectively. Guide is provided for guiding the movable block in response to energization and deenergization of the coil so that the pole pieces are movable within the respective working gaps. A contact mechanism including movable contacts is mechanically coupled to the movable block to make or break circuit.
