Title: Production of sulfurized oil or fat
Inventor: TANGE TOSHIAKI
IPC: C10N30/06
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To improve the dispersibility to reduce the load on equipment (e.g. a stirrer), cut off fresh air to assure safety during operation, and improve the conversion in reaction in producing a sulfurized oil or fat by reacting a liquid unsaturated oil or fat with molten sulfur. SOLUTION: A sulfurized oil or fat is produced by reacting an unsaturated oil or fat which is liquid, is an unsaturated oil or fat and/or an alkyl ester of an unsaturated fatty acid, and has a viscosity of 10-1,000 cP with molten sulfur heated to 125-155 deg.C. After air in a tightly sealed reactor is replaced with an inert gas, an unsaturated oil or fat is charged into the reactor; then molten sulfur in an amount of 0.5-8 mol per mol of the oil or fat is added dropwise to and mixed into the oil or fat; and the resultant mixture is heated to 120-200 deg.C and allowed to react for 15-30 hr. When an alkyl ester of an unsaturated fatty acid is used, the ester and sulfur is mixed; then the mixture is heated to 120-200 deg.C; hydrogen sulfide in an amount of 0.5-2 mol per mol of the ester is added; and the resultant mixture is allowed to react for 15-30 hr.

Filed: 1985-03-07
Abstract: PURPOSE:To make it possible that only one workman exchanges a tool in an extremely short time by holding the tool by fitting a spring pin in a concave groove whose one end the flat notch surface of a shank communicates with. CONSTITUTION:The shank 23 of a tool a is inserted into a tool fitting hole 21 and then rotated there. A spring pin 22 is therefore deformed elastically by the corner R of the shank 23, and fitts in a concave groove 26. the wedge effect and elastic deformation of the spring pin 22 presses the shoulder 25 of the shank 23 against a holder end 20a to hold the tool (a). In this case, length (g) from the shoulder 25 to the concave groove 26, distance (h) from the end 20a to the pin 22, the diameter (i) of the pin 22 and the shape of the concave groove 26 keep mutually proper relationship. In the case of demounting the tool (a), the tool a is inversely rotated so that the spring pin 22 separates from the concave groove 26. Thus the tool demounting becomes possible, and the tool exchanging can be performed easily and in a short time.

IPC: H01L21/31
Filed: 1980-04-04
Abstract: PURPOSE:To perform very stable, high quality, high temperature reaction treatment by performing high temperature reaction treatment on a semiconductor sub- strate in a crystalline quartz tube having a transparent quartz layer on the inner surface thereof. CONSTITUTION:The structure of the crystalline tube is constituted such that a cylindrical region 2 containing a heating furnace inserting region 1 comprises a high purity crystalline quartz sintered tube 4, on the inner surface layer of which a transparent quartz layer 3 is formed. One end of the sintered tube 4 is melted and sealed by a thick transparent quartz lid 6 having a tail tube 5, and at the other end, a specimen introducing part 7 comprising a thick transparent quartz tube is formed. In this constitution of the reacting tube, since the crystalline quartz tube has excellent heat uniformity, sufficient heat uniformity can be obtained even though the heat uniformity tube is not specifically provided at the outer periphery. Since the strength of the crystalline quartz tube at a normal temperature is far greater than the transparent crystal tube, the deformation life is greatly lengthend in comparison with the transparent quartz tube. As a result, the increase in the yield rates in manufacture, stabilization of the manufacturing quality, and the large reduction in manufacturing costs can be realized.
