Title: Method for purifying glycerol
Inventor: ISHIDA TOSHIROU
IPC: C07C27/00
Filed: 1988-03-31
Abstract: PURPOSE:To reduce N content in glycerol without requiring a distillation step, by binding a water-soluble protein and peptide contained in the glycerol or an aqueous solution thereof to a water-insoluble immobilized tannin and removing the water-soluble protein and peptide. CONSTITUTION:A water-soluble protein and peptide contained in glycerol or an aqueous solution thereof (preferably an aqueous solution with 30-70wt.% moisture content) are bound to a water-insoluble immobilized tannin and removed to afford purified high-quality glycerol of high practical value. The immobilized tannin is prepared by covalently binding a high polymer substance, such as water-insoluble polysaccharides, e.g., agarose, cellulose or insoluble starch, to tannin and may assume either form of fluidized and fixed beds. The above-mentioned method is advantageous, since a distillation step having disadvantages in energy consumption or yield is not required.

IPC: H01L21/314
Filed: 1983-05-11
Abstract: PURPOSE:To form an MOSFET by self-aligning method at a low temperature, by utilizing the difference in absorption coefficient with respect to electromagnetic waves and the difference in heat conductivity, and selectively forming an insulating material, a semiconductor, and metal on a substrate. CONSTITUTION:High concentration impurities are introduced into a semiconductor substrate by a conventional technology such as ion implantation, and a source region 2 and a drain region 3 are formed. Then, CO2 laser 5 is projected on the entire surface, and silicon dioxide 6 is formed by a CVD method. At this time the CO2 laser is absorbed only by a layer, whose carrier concentration is high. When the CVD method is performed utilizing the heat, the silicon 6 is formed thickly on the regions 2 and 3. Then, argon laser 8 is projected on the surface and the CVD of aluminum 7 is performed. At this time, the argon laser 8 is not absorbed by the silicon 6 due to the difference in absorption coefficient, but absorbed by the surface of the semiconductor. Only the part of a channel region 9 on the surface of the silicon 6 is heated due to the difference in heat conductivity. Therefore, aluminum, which is to become a gate electrode, is formed on the channel 9.

Abstract: PURPOSE:To prevent breakdown even though stress is applied to an element, by differentiating the lengths of terminal bodies in the axial direction, so that a space formed in the peripheral part of a diode chip is not positioned at the central part of the element. CONSTITUTION:Terminal bodies, which hold a diode chip 1, are asymmetrical and constituted by a terminal body 21, which is long in the axial direction, and a terminal body 22, which is short.
