Title: Rolling method for clad metal sheet
Inventor: HIRUTA TOSHIKI
IPC: B21B1/22
Filed: 1987-09-30
Abstract: PURPOSE:To reduce elongation difference defect and clad ratio defect parts in the top and rear end parts of a clad stock by performing usual rolling after performing preformative rolling in a specific lengthwise range from the stock top and rolling by a larger draft than that of the preformative rolling. CONSTITUTION:As for hot rolling of a clad stock, the lengthwise range of 0.2-0.8 times the total length of the stock from the stock top end is preformatively rolled. Defining a combination of the preformative rolling with a rolling by a larger draft than that of the preformative rolling from the stock rear end is one pass, then at least two passes rollings are performed. Respective peripheral speeds of upper and lower rolling rolls are made to be different; a material having less extensibility is put at a high speed roll side and rolling is performed in the above-mentioned way. Hence, the yield of the stock is improved.

Filed: 1993-09-30
Abstract: PURPOSE:To provide a method for efficiently producing diaminodiphenyl ether useful as a raw material of an aromatic polyamide for fiber and a raw material of medicines, agrochemicals, etc., in a high yield. CONSTITUTION:In a method for production of aminodiphenyl ether through a condensation reaction between a halonitrobenzene and aminophenol in a reaction medium, the objective aminodiphenyl ether is produced with high productivity by conducting the condensation reaction in the presence of (b) a condensation agent composed of an alkali metal hydroxide and/or an alkali metal carbonate and calcium oxide and/or calcium carbonate, especially a condensation agent prepared by calcining a mixture of these substances at >=130 deg.C, preferably >=150 deg.C as the dehalogenation condensation agent in (a) an aprotic organic polar solvent as the reaction medium. The condensation reaction between the halonitrobenzene and aminophenol can efficiently be conducted even at a relatively low temperature and this condensation reaction is allowed to proceed without removing water formed as a by-product or without requirement of addition of a condensation agent during the reaction. This method can inhibit formation of a by-product difficult and troublesome to separate from the objective substance and, therefore, produce high-purity aminodiphenyl ether in a high yield.

Title: Wire saw
Inventor: OKUYAMA TETSUO
IPC: B24B57/02
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To supply a sufficient quantity of slurry between a wire and a workpiece to permit efficient cutting by providing a vibration imparting means coming close to a wire row to impart vibration to the wire through a micro clearance. SOLUTION: Driving output from a driving output generating circuit 44 is supplied to magnetic field generators 21, 22. A wire 7 is drawn downward by the magnetic field from the magnetic field generators 21, 22, and the supply of driving output is stopped to return the wire 7 upward by its own elasticity, thereby imparting a specified cycle of vertical vibration to the wire 7. Vertical progressive waves are therefore generated to the wire 7, and more slurry is led in between the wire 7 and the cut part of a workpiece 11 by the progressive waves to carry out efficient cutting. Since the wire 7 and the magnetic field generators 21, 22 never come in contact with each other, the magnetic field generators 21, 22 are not cut or damaged by the wire 7.

Abstract: PURPOSE:To produce a novel epoxy resin expressed by a specific formula and having lowered residual stress after curing and improved heat-resistance and flexibility, etc., by polymerizing a phenolic compound with dicyclopentadiene, andreacting the obtained resin with epichlorohydrin. CONSTITUTION:A phenolic compound (e.g. o-cresol) is mixed with dicyclopentadiene and made to react with each other for several hours under the addition of a catalyst (a Lewis acid such as AlCl3) slowly to the mixture to obtain the resin of formula I (R is methyl or H; n is 0-5). The resin is dissolved in epich-lorohydrin, heated, subjected to the addition reaction in the presence of a catalyst (e.g. tetramethylammonium bromide), and distilled in the presence of an alkali (e.g. sodium hydroxide) to effect the removal of water by azeotropic distillation. Excess epichlorohydrin is distilled off under reduced pressure, and the residue is dissolved in an organic solvent and filtered to remove the by-products. The objective resin of formula Ii is obtained by concentrating the organic layer of the filtrate under reduced pressure.
