Title: Tig welding method
Inventor: TANAKA KAZUO
IPC: B23K9/073
Filed: 1983-02-08
Abstract: PURPOSE:To join surely beginning and end parts and to unify the bead shape by increasing or decreasing the distance between an electrode and a base metal according to the rise and fall of the respective current values when TIG welding to be accomplished without filler metal starts and stopped. CONSTITUTION:An electrode is detached from a base metal while the welding current, designated as I1(amp), with respect to the distance L1(mm.) between the electrode and the base metal is increased at a grade of I3 per second right after the start of welding at the point T1 of the time when TIG welding to be accomplished without filler metal starts. Said distance is increased up to a stationary value L2 at the point T2 of the time when the current attains the value I2. The stationary welding is performed under the condition of the current I2 and the distance L2 and while the current is decreased at a grade of I4 per second at the point T3 of the time just before the terminal end part, electrode is approached to the base metal. The welding is ended at the point T4 of the time when said distance attains L1. The electrode is run simultaneously with firing. The beginning end part and terminal end part of welding are thus surely joined and the beads are formed to a smooth surface.

Title: Method for adjusting current distribution for electroplating
Inventor: HINO YASUHIKO
IPC: C25D21/00
Filed: 1989-01-30
Abstract: PURPOSE:To easily adjust a current distribution by each of sub-segmented plating areas by combining small anodes which can be individually set at desired current values to form a assembled anode, disposing such anode to face a surface to be plated and properly adjusting the currents of the individual small anodes. CONSTITUTION:For example, 16 pieces of the small anodes 1 which can be set individually at the desired current values are combined to a net shape to form the assembled anode 5 and this anode is so installed as to face the surface 10 to be plated of a substrate 11 to be plated. A plating liquid 13 of a plating cell 14 is fed by a pump 15 to the assembled anode 5 and is brought into contact with the surface 10 to be plated through the assembled anode 5; thereafter, the liquid is returned to the plating cell 14. The currents flowing out of the small anodes 1 are insulated by an anode frame 2 and are, therefore, kept at the set values when the currents are supplied to the small anodes 1, which are respectively properly set, of the assembled anode 5 from a power source 6 in this constitution. The current distribution well reflecting the individual current set values is obtd. when the currents emit from the assembled anode 5. Desired plating patterns are formed on the surface 10 to be plated in this way.

Title: Tape tension detecting mechanism
Inventor: ETATSU YASUO
IPC: G11B15/43
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To suppress a tension drift due the change of a tape winding diameter from being generated by arranging a magnetic force generating means and a magnetic force detecting means three-dimensionally and making the change of an output due to the change of the magnetic force of the magnetic force detecting means to be roughly linear in the rotational range of a tension arm while displacing one side of the magnetic force generating means or the magnetic force detecting means relatively by tension. SOLUTION: At the time of the prescribed tension of a state B, a Hall device 5 is arranged at the roughly center of a magnet 3 and a magneti 4 and its output becomes zero. When tension becomes high, a tension arm 1 is rotated to the right direction and the balanced state of the arm 1 becomes to be in a state A. At this time, the magnet 3 whose N pole is opposed to the hole element 5 approaches the device 5 and the output voltage of the device 5 becomes a positive. When the tension becomes low, the magnet 4 whose S pole is opposed to the element 5 approaches the element 5 and the output voltage of it becomes negative. Thus, the relation of the output voltage with respect to the rotational angle of the arm 1 is made to be linear by arranging the magnets 3, 4 while allowing their poles different each other to be opposed to the Hall device 5.
