IPC: B21B1/28
Filed: 1982-10-29
Abstract: PURPOSE:To provide a titled installation which enables prevention of press sticking during coiling and un-coiling in a high speed temper rolling and finishing line which is so arranged that the strip after temper rolling is conducted as it is to a finishing stage and is coiled after a rust preventive oil is coated thereon. CONSTITUTION:An un-coiling reel 2, a welding machine 6, a temper rolling mill 4, an inspection device 7, a side trimmer 8, a coater 9 for a rust preventive oil, a splitting shear 10, and a coiling reel 3 are arranged in series. A strip 1 is then un-coiled from the reel 2 and the preceding strip and succeeding strip are connected by the machine 6. The connected strip is subjected to temper rolling with the mill 4, inspecting with the device 7, edge cutting with the trimmer 8, oil coating with the device 9, and splitting with the shear 10 and is coiled on the reel 3, whereby the strip is made into a product. Since the strip is coiled after coating of the oil, the generation of press sticking decreases considerably and the un- coiling and coiling of the strip after the coiling are avoided as far as possible. A tin black plate is thus produced at a processing speed of >=1,100m per minute.

Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To obtain a new compound that excels in electron transporting ability, has high solubility to solvents and good compatibility with binder resins, and is useful for electrophotographic photoreceptors to be used in image formation devices such as electrostatic copiers. SOLUTION: This compound, an isatin derivative, is expressed by formula 1 (R<1> is an alkyl; any one of R<2> A, R<2> B, R<2> C, R<2> D is H and the others are each H or alkyl), for example, N-ethylisatin. This compound is obtained by making an isatin derivative of formula II react with an alkyl iodide of the formula, IR<1> in the presence of sodium hydride in an appropriate solvent. The isatin derivative of formula I is used as an electron transporting material. For example, by forming a photosensitive layer which contains the isantin derivative of formula I, on a dielectric substrate, the other objective electrophotographic photoreceptor can be obtained. It is preferable for the photosensitive layer to contain an electron accepting compound whose oxidation-reduction potential is within the range of -0.8 to -1.4V, e.g. a benzoquinone-based or diphenoquinone-based compound.
