Title: Method for controlling rolling of seamless steel pipe
Inventor: SAKURADA KAZUYUKI
IPC: B21B19/08
Filed: 1982-12-17
Abstract: PURPOSE:To make the wall thickness of a final product uniform in its longitudinal direction, by controlling the position of a rolling plug while a rolling is operated in an elongator so that a rolling load is kept constant at the time of performing one pass of rolling in a succeeding plug mill. CONSTITUTION:An elongator has skew rolls 11 facing to each other, and rolls further a hollow pipe 14 formed into hollow one between a rolling plug 13 attached to the front end of a plug bar 12 and the skew rolls 11 in a piercer, and reduces the wall thickness of the pipe 14 by expanding and elongating it. At that time, the position of the plug 13 of a skew rolling mill is adjusted at the time of rolling a succeeding material so that the change with time of the rolling load of a plug mill for the succeeding material is zero, by estimating the change with time of the rolling load of the plug mill imposed on the pipe ranging from its front end to its rear end, obtained from the preceding material, is equal to the change with time of the rolling load of the plug mill for the succeeding material when assumed that the succeeding material is pierced by the same condition as that of the preceding one.

Title: Wiring board inspection device
Inventor: MATSUSHITA TATSUO
IPC: G01R31/28
Filed: 1990-08-22
Abstract: PURPOSE:To prevent re-inspection, inability of inspection, or damage to a wiring board by measuring deviation between a probe and an inspection position using a photo sensor and compensating for deviation with an inspection position. CONSTITUTION:A wiring board 1 is set to an inspection table 3 and a ground pattern 12 and a control part 62 of a control device 6 are connected. One inspection data is transferred from the inspection data storage part 61 to this control part 62 and a table 3 is transferred to coordinates of this inspection data. Then, a photo sensor 5 measures deviation between an inspection position 2 and a probe 4, compensates for coordinates of the inspection data if there is deviation and moves the table 3, and performs the same processing as in measurement of deviation. If there is no deviation, a control part 65 inspects a floating capacity CS between a wiring pattern 11 and a grounding pattern 12, indicates an error if it does not agree with the floating capacity of the inspection data, and then prints it out 63. Therefore, since the probe always comes into contact with inspection position, re-inspection and inspection inability are not required and there is no counter to areas other than the inspection position, thus preventing a wiring board from being damaged.

Abstract: PURPOSE:To obtain an excellent film whose surface characteristics do not deteriorate with time by preparing a polymeric resin film having specified convex parts being arranged in about a definite order on the film surface, dyeable with osmic acid and monolithically fixed with the film. CONSTITUTION:Preferable characteristics of a film comes out by arranging convex parts dyeable with osmic acid to about a definite direction and almost uniformly. Flatness and easy-sliding properties of the film depends on the size of the convex parts on the film surface. It is preferable that the height, width, no. of the convex parts dyeable with osmic acid on the film surface observed from the cross section cut parallel to the arranging direction of the convex parts are 30-300Angstrom , 100-5,000Angstrom  and 0.5-50/mum of the surface respectively. It is more preferable that those values are 50-300Angstrom , 100-3,000Angstrom  and 1-20/mum respectively. When the height and no. of the convex parts are smaller than 30Angstrom and 0.5, the easy-sliding property is not satisfactory. On the other hand, when the height is larger than 300Angstrom  and the no. is larger then 50, flatness of the surface is lost and at the same time, adhesiveness is also lost.

Title: Magnetically shielded optical fiber
Inventor: TANABE KUNIO
IPC: G02B6/44
Filed: 1987-09-03
Abstract: PURPOSE:To facilitate magnetic shielding by incorporating a superconducting material in one of clad layers. CONSTITUTION:A single-mode optical fiber 13 is provided with a layer 11 of silicon resin containing a superconducting material. For the purpose, when this layer 11 is made superconductive, the influence of magnetism applied to an optical fiber 8 from the outside is removed. Namely, the material in the superconductive state never transmits magnetism, so the magnetism passes through the coating detouring around the part of the layer 11 and no lines of magnetic force, therefore, enter the optical fiber 8 in it. Consequently, Faraday effect induced in the optical fiber with earth magnetism, etc., is suppressed. The magnetic shield effect can be increased more and more as the concentration of the superconductive material contained in the layer 11 is increased more and more, thereby reducing the quantity of magnetism leaking in the optical fiber 8.

Title: Fin material for heat exchanger
Inventor: YOKOTA YUZO
IPC: F28F1/12
Filed: 1985-10-03
Abstract: PURPOSE:To have condensate absorbed into the surface layer of a fin and to treat the condensate in the layer, by applying a specified organic compound on a fin material. CONSTITUTION:An adhesive layer is formed on the surface of a fin material in the first place. As for the adhesive, conventionally known heat-hardening resin adhesive or thermoplastic resin adhesive can be used. A resin of high water absorption capacity is a high polymer which can absorb and hold water more than 100 times as much as the weight of itself. Starch - acrylonitrile graft polymer, acrylic acid - acrylonitrile copolymer, and so forth can be given as examples. Especially the cross-linking agent of a polymer, of which main constituent is polyacrylate, is very suitable because it has very high water absorption capacity. A highly water absorption resin layer can be formed by applying a highly water absorptive resin solution on the adhesive layer or by spraying or applying highly water absorptive resin powder on the adhesive which is not yet hardened or which is still in the soft state. When the fin material processed in such a manner is used for the fin of a heat exchanger, condensate is absorbed and held in the highly water absorptive resin. The condensate gradually drips under the weight of its own and is removed from the surface of a fin.
