Title: Processing method for silver halide color photographic sensitive material
Inventor: ISHIKAWA TAKATOSHI
IPC: G03C7/42
Filed: 1987-09-03
Abstract: PURPOSE:To improve desilverability and to prevent the conversion of a dye into a leuco-body by processing a silver halide color photographic sensitive material with a bleach-fix bath contg. specified aminopolycarboxylic acid, bromide ions and iodide ions after color development. CONSTITUTION:A silver halide color photographic sensitive material is color- developed and processed with a bleach-fix bath contg. aminopolycarboxylic acid having >=300mol.wt. and 1X10<-2>-2mol./l bromide ions and/or 5X10<-4>-5X10<-2>mol./l iodide ions. In case of <1X10<-2>mol./l bromide ion concn., no bleach-fix accelerating effect is exhibited. The amt. of residual silver is not sufficiently reduced in case of <5X10<-4>mol./l iodide ion concn. and defective desilvering is caused in case of >5X10<-2>mol./l. Thus, in spite of rapid processing, desilverability is improved and the conversion of a dye into a leuco- body can be prevented.

Title: Method and fixing jig for fixing multi-core optical fiber
Inventor: YANAGI AKIRA
IPC: G02B6/255
Filed: 1988-09-01
Abstract: PURPOSE:To splice multi-core optical fiber cables with each other by fusion without irregularly arranged end faces by holding and fixing each cable with two press lids, with the cable being turned by 180 deg. between the lids. CONSTITUTION:A multi-core optical fiber cable 10 is held by a jig 20 by closing the press lid 22a on the front end side of the jig 20 after housing the cable 10 in a linear optical fiber housing groove 23 provided in the lower base plate 21 of a jig 20. Then the state A of the figure is formed by turning the cable 10 by 180 deg. in such state and the succeeding section of the cable 10 is fixed in another groove 23 by closing a press lid 22b after housing the cable 10 in the groove 23. Thereafter, the front end of the cable 10 is spliced with another cable by fusion after aligning the cables to each other. While the stress and tension produced by the movement of the cables can be transmitted to the front ends when the press lid 22b only is used, they cannot be transmitted to the front sections when the cables are turned in such way, because the stress and tension are completely blocked at the turned section A. Therefore, the cables can be spliced with each other by fusion without irregularly arranged end faces.

Title: Reader
Inventor: MORIHIRO JIYUNJI
IPC: H04N1/12
Filed: 1987-09-02
Abstract: PURPOSE:To reduce the thrust pressure of an original by lowering the thrust pressures of a reading means and a reading roller and driving feeding and pressing rollers provided before the reading roller synchronously. CONSTITUTION:An original 6 is carried by a feeding roller 10 and a pressing roller 11 and, simultaneously, read in being thrust by an image sensor 7 at a reading roller 8. During such a reading action, an original thrust pressure by the image sensor 7 and the reading roller 8 is lower compared with a conventional one, and therefore, there is a fear that a feeding nonuniformity is generated to the original by means of only the reading roller 8. Then, since the feeding roller 10 and the pressing roller 11 are provided before the reading roller 8 and synchronously driven, the original can be fed at a proper speed by the feeding roller 10 and the pressing roller 11. Since the original 6 is not tightly thrust by the image sensor 7, a noise can be reduced.

Title: System for preventing mismachining in machine tool
Inventor: MASUDA NOBUYUKI
IPC: B23Q11/00
Filed: 1986-09-17
Abstract: PURPOSE:To prevent mismachining, by setting a motion inhibiting region in a machine tool by a program independently of the machining program while supervising whether or not a detected position is located in the inhibiting region with a correction considering the size of a tool and its mounting direction and interrupting work when the position of the machine tool is placed in the inhibiting region. CONSTITUTION:A motion inhibiting region of a lathe 1 is set by a program independently of the machining program. And the lathe 1, which supervises whether or not a position, detected by a detector, is located in the inhibiting region applying a correction, considering the size of a machining tool 13 and its mounting direction, to the coordinates of the lathe 1, interupts work by feeding a stop instruction to an NC unit 2 of the lathe 1 when its position is placed in the inhibiting region. In this way, since the lathe 1, to which a value of an edge point R of the tool 13 and its direction are given as data, obtains points on the circumference of the edge point R checking whether or not these points are placed in the machining inhibiting region on condition the same to the actual condition, mismachining due to misoperation and misprograming can be prevented by inhibiting the edge point from being placed in the inhibiting region.
