Title: Manufacture of bonding wire
Inventor: TOBIYAMA TAEKO
IPC: C23F1/00
Filed: 1995-05-25
Abstract: PURPOSE: To provide a manufacturing method of a wire wherein the exchange frequency of a capillary can be reduced by increasing the number of times of bonding until abnormality generation due reverse deformation when a loop is formed. CONSTITUTION: A surface layer eliminating treatment is performed on an intermediate yarn stock obtained by plastic-working an ingot. After a wire is formed by stretching the yarn stock, final annealing and post-treatment of wire lubricant coating are performed. Thereby adhesion of the wire lubricant is increased, troubles causing loop abnormality are hardly generated, and the capillary exchange frequency is reduced.

Title: Passage switch valve with stop function
Inventor: HASHIOKA YOSHIO
IPC: F16K3/08
Filed: 1983-07-11
Abstract: PURPOSE:To eliminate influence of hydraulic pressure upon discs and to keep constant the contact surface pressure of a fixed disc and a movable disc by providing a movable disc close to a fixed disc with a disc cover having a passage axially pierced therethrough. CONSTITUTION:A movable disc 5 is slidably rotated with a disc cover 6 for a fixed amount on a fixed disc 4 by operating a lever 9 to connect or intercept a water passing hole 5a or 5b of the movable disc 5 and water passing hole 4a or 4b of the fixed disc, thereby stopping water and adjusting the flow rate. The disc cover 6 is adapted to seal up the outer peripheral edge of a comparatively narrow inlet passage through a packing 14 and simultaneously to connect an outlet passage 6 to the water passing hole 5a of the movable disc.

Title: Manufacture of optical fiber cable
Inventor: KITAYAMA YOSHINOBU
IPC: H01B13/02
Filed: 1985-06-11
Abstract: PURPOSE:To facilitate control over the amount of unwinding of an optical fiber and to increase a manufacture speed by inserting the optical fiber into the spiral groove of a center member at pitch smaller than in the beginning and resetting the pitch to the initial state in a final take-up process. CONSTITUTION:The pitch of the spiral groove of the center member 1 is smaller than the initial pitch between a payoff drum 5 and a take-up drum A and the optical fiber 2 is inserted into the spiral groove of the center member 1. On the other hand, a take-up drum B is rotated in the opposite direction from the payoff drum 5 between the take-up drum A and take-up drum B, so the pitch is reset to the initial state and the difference in the standing rate of the optical fiber 2 between the payoff drum 5 and take-up drum B is therefore the excessive length of the optical fiber 2 when it is inserted into the spiral groove of the center member 1.

Abstract: PURPOSE:To prevent hindrance of the next process and to prevent damage by making the distance of falling down of tubular bodies constant by storing tubular bodies in plural storing grooves classifying the tubular bodies, and detecting the number of stored and delivered tubular bodies, and adjusting moving-up and- down of a lifter according to the number of stored tubular bodies. CONSTITUTION:The tubular body storing device 6 opens the cover plate 8 of a storing groove that stores the tubular body and erects a stopper 10. Under this state, a tubular body regulated to specified length moves while rolling on a slanted face and falls down in the storing groove and stored. At this time, a storing confirming sensor turns on, and is inputted to a controlling box 16, and added to the number of tubular bodies in the storing groove 7a. At the same time, the controlling box 16 gives a command to a lifter 11 to descend by one tubular body. Thus, the controlling box 16 detects the number of tubular bodies in each storing groove 7 at all times by signals of each sensor and gives manufacture request signals D1 or manufacture suspension signals D2. When a delivery signal L of specified tubular body is inputted to the controlling box 16, the controlling box 16 gives a command to the lifter 11 of specified tubular body. The tubular body is lifted and delivered, and the number of tubular bodies in the storing groove is subtracted.
