摘要： PROBLEM TO BE SOLVED: To realize a connection structure and a method for improving a printed wiring board in connection reliability and for reducing its manufacturing cost. SOLUTION: The lands 11a of a conductor pattern 11 formed on the connection surface of a flexible printed wiring board 10 formed of thermoplastic resin as an insulating board material are electrically connected to the lands 5a of a conductor pattern 5 formed on the connection surface of a rigid printed wiring board 1 through Sn plating 7. The lands 5a and 11a of the printed wiring boards 1 and 10 are directly connected together through the intermediary of the Sn plating 7, so that the assembly composed of the boards 1 and 10 is superior in reliability of connection. The Sn plating 7 is bonded to the lands 5a and 11a by diffusion of metal, so that the assembly is superior in connection strength. Furthermore, the Sn plating 7 can be easily regulated in film thickness, so that a solder bridge which is apt to occur in a printing solder process can be easily prevented from occurring between adjacent bridges.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing an inexpensive, highly corrosion resistant heat exchanger formed of stainless steel. SOLUTION: A chromium brazing filler metal layer 21 is formed after applying the Cr electroplating of a plating thickness of 15 μm on both end faces of first and second forming stainless steel plates 1 and 2 alternately stacked on each other in the thickness direction, and then a nickel brazing filler metal layer 22 is formed after applying the Ni-P plating of a plating thickness of 35 μm on the chromium brazing filler metal layer 21. The highly corrosion resistant heat exchanger is manufactured by applying the integral brazing with the chromium brazing filler metal layer 21 and the nickel brazing filler metal layer 22 interposed between the first and second forming plates 1 and 2. A highly corrosion resistant brazing filler metal 31 having an alloy composition consisting of Ni-Cr28-P8, etc., is obtained on both end faces of the first and second forming plates 1 and 2. A fine metal structure in the highly corrosion resistant brazing filler metal 31 can be realized, and generation of cracks in the interface of the metal structure can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a solenoid valve miniaturizing the body, reducing the number of components, and reducing the assembling man-hours and manufacturing costs. SOLUTION: A non-coating part 13a is formed in a spool 30 side end face of a plunger 13 so that a position of the spool to the feed current value in coil energization is prevented from being dispersed without any relation with the dispersion of the film thickness of the coating film 130. The output pressure of hydraulic oil is prevented from being dispersed relative to the feed current value so as to enhance the accuracy of hydraulic control. The non-coating part 13b is formed in the counter-spool side end face of the plunger 13 so that the assembling of the plunger 13 is facilitated so as to reduce the assembling manhour. This constitution can also eliminates the post-processing such as polishing and wrapping finish for controlling the coating film thickness and securing the accuracy. The manufacturing cost can be thus reduced.
