Title: Electroplating device
Inventor: FUKUDA SHUZO
IPC: C25D5/08
Filed: 1987-04-13
Abstract: PURPOSE:To prevent the infiltration of air into the upper surface of an electrode by providing a plating soln. storage communicating with a gap between the electrode and a strip above a nozzle for supplying a plating soln. into the gap, and forming a seal nozzle for supplying the plating soln. at right angles to the strip. CONSTITUTION:The strip 13 is traveled downward between the anodes 14, and the plating soln. is discharged into the gap 18 between the electrodes 14 and the strip 13 from a nozzle header 16 provided at the upper part through the nozzle 17. At this time, the side of the nozzle header 16 is closed, and the plating soln. storage 19 is formed above the nozzle 17. The seal nozzle 21 is further fixed to the nozzle header 16 at right angles to the strip 13. By such a constitution, when the plating soln. is supplied from the nozzle 17 and plating is carried out, a part of the plating soln. from the nozzle 17 enters into the plating soln. storage 19 through a plating soln. passage 20, and a plating soln. surface is formed. By this method, the infiltration of air, etc., into the gap 18 from the upper part due to the traveling of the strip 13 is prevented, and the ascension of the plating soln. into the plating soln. storage 19 is blocked.

Title: Oil outflow preventing lining
Inventor: NONAKA YOSHINORI
IPC: B63B11/04
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To flexibly deform a lining to avoid breakage even when it is pressed by a colliding material penetrating into a tank and the bursting edge of an outer plate member of the tank which is broken to be immersed inside the tank by lining a lining material along the inner surface of an oil storing tank with slackness in the longitudinal and horizontal directions. SOLUTION: One of a tank and another coiling material collides with the other thereof to break an outer plate 2 of a tank. A lining 1 is pressed by a colliding material 01 penetrating into the tank and the burst edge of the outer plate of a tank, which is broken by a collision with the colliding material 01 to be immersed inside the tank. The lining 1 is, however, flexibley deformed to avoid breakage. Further, as the lining material has a non-oil permeability, even if the outer plate of the tank is broken, the lining 1 continues to retain oil 03, whereby the oil 03 in the tank is kept from flowing into the outside of the tank, for example, the sea water through the broken part of the tank.

Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To provide multi-branched optical line testing method and device capable of automatically detecting fault generation time, a fault generation line and a fault generation position in a multi-branched optical line. SOLUTION: In a step S1, an optical pulse is made incident upon a multi- branched line and response light is photoelectrically converted into an electric signal.

In a step S4, the logarithmic waveform data of each range is Hough- transformed. In a step S5, the Hough-transformed logarithmic waveform data is processed by center value filtering processing. In a step S6, the center value filtered logarithmic waveform data are transformed by inverse Hough transformation. In a step S7, the inverse Hough-transformed logarithmic waveform data are converted by inverse logarithmic transformation and then attenuation constant separation analysis is executed.  In a step S8, attenuation constants are collected by repeating respective steps S1 to S7, and in a step S9, a fault on the multi-branched optical line is judged based on the attenuation constant.

Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To match a groove to the behavior of an optical fiber tape by previously storing a larger tape molding in the groove, filling a gap in the groove and removing the tape molding to form a tape acceptance part. SOLUTION: While a tape molding is stranded, extrusion is performed to fill a resin 4 in a gap between the tape molding 3 and a groove 2. After the resin is hardened, the tape molding 3 is pulled outward in the radial direction of a spacer 1. In a normal part A, the resin 4 resides at both sides of the groove, in a reverse part C, the resin 4 resides at the exterior angle side of the curved groove 2 and in a transition part B, the resin 4 resides only at a triangular area ranging from the groove bottom to the groove wall. The resin 4 residing in the groove 2 forms a tape acceptance part 5 which is completely matched to the behavior of the tape molding 3, as well as the behavior of an optical fiber cable tape. In this way, an optical fiber tape 6 is stranded on the spacer 1 with the tape acceptance part 5 formed in the groove 2 so as to fitted in the tape acceptance part 5.

Filed: 1987-04-14
Abstract: PURPOSE:To prevent the incomplete penetration at the toe and central part of a bead by synchronizing the oscillation of a welding torch with the travel of a torch oscillating device to stop a travel device till it starts traveling and attains the other end of the oscillation width from the vicinity of its center. CONSTITUTION:The welding torch is oscillated with a simple pattern and in synchronization with this oscillating period, the travel and stoppage of the torch oscillating device are repeated alternately. Or, the welding torch is oscillated and changed in a rectangular wave shape and a curved wave shape at the high speed and low speed. The torch movement from one end to the other end of a groove is accompanied by the travel of the travel device and the travel of the travel device is stopped in the vicinity of the central part of the oscillation width and it is moved by only the torch oscillation. By this method, the incomplete penetration at the toe and central part of the bead is prevented and the automatic welding of a joint such as a horizontally fixed pipe, etc., is performed.

Title: Film cut device
Inventor: OMORI SHOZO
IPC: B26D1/40
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a film cut device capable of firmly bringing a die roll and an anvil roller into contact with each other by prescribed pressure without generating a cutting defective. SOLUTION: This device has a die roll 21 having a prescribed shaped blade on cylindrical peripheral surfaces arranged in the vertical direction and an anvil roller 24 receiving the blade of the die roll 21. A film is made to be cut into a blade shape by bringing the film into contact between the blade and the anvil roller 214 by prescribed pressure when the film passes between the die roll 21 and the anvil roller 24. Prescribed pressure when the film is held is made to be generated by supporting the die roll 21 so as to move in the vertical direction and directly imparting energizing force downward which is generated from a fluid cylinder 30 to the die roll 21.  As a result, the die roll 21 does not bend and the blace can be brought into contact with the whole surface of the film by prescribed pressure because reaction from the anvil roller 24 is directly received by the die roll 21 which is thick in the diameter and strong in rigidity.

CONSTITUTION:At a synthetic resin-made cylindrical sliding member 2 a plurality of leg pieces 25 are placed vertically and on their outside clicks 26 are formed. On the outside of the click taper surfaces 26a, 26b diverging and converging toward the rear side of the sliding member are successively formed in the tip direction. A frame 3 is inserted between the rear surface 23b of the peripheral edge part 23 of the member 2 and the diverging taper part 26a, and the member 2 and the frame 3 are able to slide and contact under pressure by the use of the inside taper part 32b formed at the inner circumferential edge part 32 of the frame 3 and the taper surface 26a. A cavity part 27 is formed near the inside of the part 26a. Pressurized contact between the part 32b of the frame 3 and the part 26a is therefore elastic and flexible and the feeding of sliding operation can be improved.
