Title: Method for alloy plating excellent in corrosion resistance and plated product
Inventor: KIMURA TAKAO
IPC: C25D5/10
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To obtain plating free from the defects of color tone, spreadability and operability and having corrosion resistance equal to or above that of nickel- chromium used in the open air by combining hard tin alloy plating with base plating and nonconductive fine particle eutectoid plating. SOLUTION: The product to be plated is successively applied with base plating, nonconductive fine particle eutectoid plating and hard tin alloy plating. As the hard tin series alloy plating, tin-nickel alloy plating, tin-cobalt alloy plating, tin-nickel-copper alloy plating, tin-nickel-phosphorus alloy plating or the like are given, and these alloy plating has >=400 Hv hardness which is sufficient as the outermost layer plating. This hard tin alloy plating is executed at a thickness of about 0.02 to 10 μ for obtaining excellent corrosion resistance. For obtaining a plated product by this method, working by a barrel can be executed as well as working by an ordinary rack, and the working efficiency can exceedingly be improved.

Filed: 1989-07-14
Abstract: PURPOSE:To enable a semiconductor device to be easily switched to a redundant circuit and to be easily improved in reliability by a method wherein an insulating layer which is formed sealing up a redundant circuit switching member or a fuse is provided. CONSTITUTION:A semiconductor device of this design is switched to a redundant circuit in such a manner that a laser irradiation part E located at the upside of a weld part 103 is irradiated with laser rays. The weld part 103 is heated to vaporize through irradiation with laser rays, a fuse 100 is prevented from exploding as insulating films 106, 107, and 109, and a protective film 110 which envelop the weld part 103 are strong enough to withstand the vapor pressure of the part 103. Therefore, the insulating films 107 and 109 and the protective film 110 are never broken, so that a cavity is generated inside the insulating film 106. As the vaporized weld part 103 is made to adhere uniformly to the wall face of the cavity, weld parts 101 and 102 are electrically connected together. By this setup, a redundant circuit switching member or a fuse high in percentage of success and reliability can be formed at a low manufacturing cost.

Title: Method for controlling dwelling in motor-driven injection molding machine
Inventor: KAMIGUCHI MASAO
IPC: B29C45/57
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling dwelling for preventing collision of a screw. SOLUTION: A speed command Pc output from a differential amplifier 30 is sequentially compared with a speed command Vc from a position controller 26 with respect to amplitude relation by a comparator 31 based on a deviation of a detected injection pressure Pf from a set injection pressure Ps. A changeover switch 32 is operated by an output from the comparator 31, and the speed command of smaller value of the commands Pc and Vc is input to a speed controller 27 to drive an injection servo motor 2. When filling of resin becomes insufficient so that a resin pressure in later half of the injection does not arrive at the set value Ps, the command Vc < the command Pc is satisfied.  Further, since the command Vc from the controller 26 becomes '0' at the stage of arriving the screw at a target position so that a positional deviation becomes '0', the screw is automatically stopped at the target position to prevent collision of the screw with a cylinder.
