Abstract: PURPOSE:To obtain the titled compound useful as an intermediate for pharmaceuticals, agricultural chemicals, liquid crystals, etc., from an inexpensive raw material in high yield, by using a,a,a,a',a',a'-hexafluoroxylene as a raw material and reacting the material with a strong acid, thereby selectively hydrolyzing the raw material. CONSTITUTION:The objective compound can be produced by using a,a,a,a',a',a'- hexafluoroxylene as a raw material and reacting the material with a strong acid (e.g. fuming sulfuric acid, fluorosulfuric acid, sulfuric anhydride, trifluoromethane-sulfonic acid and antimony pentachloride) in sulfuric acid. The amount of the strong acid is preferably about equivalent to the trifluoromethyl group to be hydrolyzed.

Abstract: PROBLEM TO BE SOLVED: To make a plate undeformable even if a jig is repeatedly used many times by providing the wafer sticking surface to which semiconductor wafers are stuck and notch grooves extending inward from the peripheral edge, on the plate. SOLUTION: This substrate polishing jig 20 is composed of a plate 11 formed of heat resisting glass composed of a transmissive material having points 42a to 42d being height adjustable polishing quantity adjusting means, four notch grooves 16a to 16d extending toward the peripheral edge from the respective points 42a to 42d and the sticking surface to which semiconductor wafers 12a to 12d are stuck. The four notch grooves 16a to 16d prevent deformation such as a warp by the repetition of the extension/contraction of the plate 11 itself, and operate to release stress applied to the plate 11 by thermal expansion of the points 42a to 42d arranged in the respective notch grooves 16a to 16d. Therefore, even if thermal expansion is repeated by using this jig 20 many times, a warp and a crack are not caused in the plate 11.

Title: Operation method of sintering machine
Inventor: OYAMA KOICHI
IPC: C22B1/16
Filed: 1994-04-11
Abstract: PURPOSE:To stabilize high product strength and improve the product yield by adjusting the amts. of cake in the upper layer and lower layer of raw material layers by gradient compounding to segregation indices of a specific range according to the points where the waste gases of a sintering machine are circulated and the rate of circulation. CONSTITUTION:Raw materials to be sintered compounded with the cake are charged from a charging hopper 15 onto a sintering bed 14. The upper part of a raw material layer 16 is ignited in an ignition furnace of a sintering machine 10A. While the waste gases 11 are sucked during the passage of the raw material layer 16 through a heat retaining furnace, the waste gases are allowed to fall gradually to the lower layers in a red hot zone 17 kept at a high temp. Combustion is ended before the waste gases are discharged from the sintering machine 10A. At that time, the amts. of the cake in the upper and lower layers of the raw material layer 16 are adjusted by gradient compounding at the segregation indices from 0.7 to 1.2 according to the points where the waste gases of the sintering machine 10a are circulated and the rate of circulation. As a result, adequate heat balance is obtd. over the entire part of the layers on the sintering bed 14. The red hot zone 17a of the lower layer is thus made thin and the air permeability is improved.

Title: Electrolyte for driving electrolytic capacitor and electrolytic capacitor using it
Inventor: MORI YOSHIYUKI
IPC: H01G9/035
Filed: 1995-04-24
Abstract: PURPOSE: To improve variations in the capacitance and leakage current of an electrolytic capacitor at high temperature by adding a phenol derivative, expressed by a specific formula, to solvent and solute. CONSTITUTION: An electrolyte for driving electrolytic capacitors is prepared by adding a phenol derivative, expressed by the formula (however, n is a number of 3-8), to solvent and solute. In this electrolyte the phenol derivative is absorbed to the surfaces of anode foil and cathode foil, and a uniform protective film is formed there. This prevents hydration and the like of the anode foil and cathode foil, and improves variations in the capacitance and leakage current of an electrolytic capacitor at high temperature. Especially, since phenol derivatives are excellent in absorption to an electrode foil as compared with prior art amino acids, they have protective effect not only on a cathode foil but also an anode foil, where any unevenness of a protective film leads to increase in leakage current. It is preferable that 0.001-10.0wt.% of the phenol derivative should be added to electrolyte of a weight.
