  • Patent number: 5045243
    Abstract: A method for dry fractionation of a fat or oil wherein a non or less-laurin fat or oil is cooled and then fractionated into a solid fraction and a liquid fraction, said method comprising cooling the fat or oil in an apparatus having cooling means to crystallize it in a desired crystallization degree, then crushing it physically to fluidize it, and then pressing or filtering it to fractionate into the crystalline solid fraction and the liquid fraction.

  • Patent number: 4994140
    Abstract: In a method of processing a compound semiconductor wafer to deposit or form a specific layer on a wafer surface, to partially remove the specific layer to partially expose the wafer surface, and to etch a partially exposed area of the wafer, etching is performed by irradiating an electron beam and a specific gas which may be, for example, chlorine gas, bromine gas, iodine, or their compounds. Portions subjected to irradiation of both the electron beam and the specific gas are etched from the wafer. The specific layer is deposited or formed in the form of an oxide layer on the wafer surface by spraying an oxygen gas onto the wafer surface with light irradiated on the wafer surface. Such an oxide layer may be either an adsorbed molecular layer of the oxygen gas or a chemically reacted layer which results from reaction of the oxygen gas with the wafer by the help of irradiation of the light. Alternatively, the specific layer may be either a sulphide layer or a nitride layer.

  • Patent number: 4795569
    Abstract: A method for dry fractionation of a fatty material which comprises cooling the fatty material and then fractionating the material into a solid fraction and a liquid fraction, said cooling being carried out by introducing the fatty material in a fluid state into a filter chamber of a filter apparatus having pressing function and maintaining the fat material therein at a crystal deposition temperature until a predetermined amount of crystals are formed, and said fractionation being carried out by pressing the filter chamber to fractionate the fat material into the solid fraction and the liquid fraction.
