Abstract:
A substrate 1 has a coil 5 that is a choke coil part and, for example, is used for controlling a motor. At the substrate 1, an electronic component mounting part 9 is formed such that a circuit conductor therein is to be exposed to outside. A portion other than an externally connected portion such as the electronic mounting part 9 is covered with substrate-forming resin to form an injection molded circuit board 3. The coil 5 arranged at the substrate 1 (the injection molded circuit board 3) is provided for smoothing current inputted from outside. A core part 7 is formed at the coil 5 by core-forming resin such that the coil part 7 covers at least a center core part 6 of the coil 5.

Abstract:
A method, and structure formed thereof, for processing an exposed conductive connection between an thermal inkjet print head device (12) and a flexible tape circuit (15) connectable to control signals for driving the inkjet device. According to the method of processing, the exposed conductive connection (14, 16) is electrophoretically plated with a polymer (19) to protect it against corrosive damage by coupling the exposed conductive connection (14, 16) to a first voltage potential and immersing it into an electrophoretic polymer solution in contact with an electrode at a second voltage potential thereby establishing a current between the electrode and the exposed connection (14, 16) such that the exposed connection (14, 16) is coated with a thin film of polymer (19) of uniform thickness.
Abstract:
A wiring board formed with electric circuits is provided, wherein said electric circuits are formed by comprising straight bus bar segments (11-13), each of the straight bus bar segments having contact portions (11a-13a) at opposite ends thereof, said wiring board having means for bringing the respective contact portions into electrical contact.
Abstract:
The invention relates to a laminated substrate producing method for mounting semiconductor chips, wherein at least respective metal and plastic structure films having respective different recurrent contour are laminated together in such a way that a material strip is obtained and said lamination is followed by perforations or cuttings, the inventive method is characterised by at least one of the following steps: A) the films are structured in such a way that the superposition thereof makes it possible to obtain the areas which are devoid of overlap through the total thickness thereof; B) the films are not laminated through the total thickness of the laminate in partly recurrent areas; and C) the reccurent cross-sections of the reccurent contours are curved from the surface of the laminated strip starting from said laminate.
Abstract:
An electric connection box is provided with an upper case, a lower case which is coupled with the upper case when the upper case if fitted to the lower case, a connector housing which connects external connectors, a terminal section composed of a plurality of terminal pieces which are arranged between the upper and lower cases and positioned in parallel with each other in the connector housing, one or a plurality of bus bars having bus bar main bodies integrally formed with the terminal section, and insulators which are provided at least between each terminal piece and couple and fix the terminal pieces with and to each other. The pitch disturbance and deformation of the narrow terminal pieces are prevented, because the insulators couple the terminal pieces with each other.
