Title: Partial plating device of lead frame
Inventor: TOKUNAGA TAKAO
IPC: C25D5/02
Filed: 1983-02-01
Abstract: PURPOSE:To maintain the uniform plating current distribution in the plating part of a lead frame and to make plating thickness uniform by inserting an auxiliary anode plate between a box body and a mask, and connecting the same to an anode. CONSTITUTION:An auxiliary anode plate 11 consisting of a conductive material having resistance to a plating soln. is inserted between a box body 3 and a mask 4 and is connected to the anode (+) of an electric power source so as to be maintained at the same potential as the potential of a nozzle 5. A hole part 11a projecting slightly inward from the guide hole 4a of the mask 4 is provided. When electricity is conducted from the power source, the plate 11 acts as the anode upon impressing of the anode (+) of the nozzle 5, by which a lead frame 1 is plated. The plating current flows from the anode potential in the hole part 11a of the plate 11 to the plating place of the frame 1 in this stage in addition to the plating current passing the plating flow discharged from the nozzle 5 and flowing to the plating position of the frame 1. Therefore, the plating current flows uniformly to the plating place and plating in a uniform thickness is accomplished.

Title: Manufacture of silver-plated wire rod
Inventor: NAKATSU AKIYOSHI
IPC: C25D7/06
Filed: 1989-01-27
Abstract: PURPOSE:To obtain the silver-plated wire rod having no discoloration on the surface and having excellent solderability and corrosion resistance by subjecting a wire rod of which a core wire of copper-series metal is plated with silver-series metal to wire drawing at specified working rate with interposed heat treatment in the specified temp. range. CONSTITUTION:A core wire of copper or copper alloy is plated with silver or silver alloy and the obtd. wire rod is subjected to wire drawing at >=30% working rate in a secondary stage. The wire rod is subjected to heat treatment at 500 to 800 deg.C in a third stage and the obtd. wire rod is subjected to wire drawing at <=15% working rate in a fourth stage to obtain the objective wire rod. In the secondary stage, at the time of <30% working rate, recrystallization structure of the silver-series metal does not grow into the fine and uniform one in the third stage to cause the lowering of solderability and corrosion resistance. In the third stage, at the temp. of <500 deg.C, recrystallization structure of the silver-series metal does not grow satisfactorily and rapidly and, at >800 deg.C, the alloying between the silver-series metal and the copper- series metal progresses drastically to cause discoloration. In the fourth stage, at >15% working rate, the hardening of the silver-series metal progresses excessively to vanish the flexibility.

Title: Method for stripping conductor of shielded portion of coaxial cable
Inventor: SATO SADATOSHI
IPC: H02G1/12
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To provide a method for stripping the conductors of the shielded portions of a coaxial cable, wherein the conductors of the shielded portions can be stripped with stability for a long time without machining with an edged tool, and the conductors of the shielded portions of a multicore coaxial cable can be stripped simultaneously moreover under the same conditions. SOLUTION: An coaxial cable 1 is formed by coating a center conductor with an inner insulator 6, coating the inner insulator 6 with an outer conductor 3, and coating the outer conductor 3 with an outer coating insulator 2. The method for stripping coaxial cables comprises a process, in which part of the outer coating insulator 2, is removed to expose the outer conductor 3 and a process in which the exposed outer conductor 3 is dissolved in etching liquid 4. Thus the conductor of a shielded portion can be stripped stably over a long time. When the conductors of the shielded portion of a multicore coaxial cable is stripped, there is no need for striping the cores one by one, and the cores can be stripped simultaneously as well as under the same conditions.
