Inventor: KATO TAKASHI
IPC: H05K3/18
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a printed wiring board, which can form fine wiring pattern. SOLUTION: In this manufacturing method, a through-hole 14 is formed on a substrate 10 having copper foils 12 on both faces, and copper 16 is plated after a catalyst processing. The through-hole is filled with an insulating material 18, a copper layer on a surface is etched so that the catalyst layer does appear and a thin copper layer 12' is left. An insulating material 19, protruded from the surface is polished and flattened and copper 20, is plated on a surface containing the region of the filled through-hole. The copper layer on the surface is patterned, and a wiring pattern 23 is formed. The copper layer is thinned, so that the catalyst layer is not exposed and therefore a wiring pattern is made fine, without the occurrence of the trouble of peeling of a wiring conductor, and the trouble of an air trap can be also solved.

Title: Shaving apparatus of rail head part
Inventor: FUREDEI SHIYOIHITSUERU
IPC: E01B31/17
Filed: 1984-05-16
Abstract: This machine comprises at least one grinding unit mounted to a grinding base. Each unit comprises a frame secured to the grinding base. The grinding wheel is driven by an electric motor, suspended from the frame by means of four rocker arms constituting two parallel-motion suspension systems. The lower rocker arms are levers of the first order and the grinding pressure is applied for one of the rocker arms by the piston rod of a hydraulic cylinder rigid with the frame and adapted to position the grinding wheel in relation to the rail, and for the other rocker arm by the piston rod of a pneumatic cylinder also rigid with the frame. This pneumatic cylinder determines the operating pressure of the grinding wheel on the rail. The operative face of the grinding wheel is parallel to the plane of the theoretical tangent to the rail profile. A right-angled lever is pivoted to a projection of the frame and provided at one end with a stud facing the grinding wheel. During the forward feed of the grinding wheel this stud moves from an inoperative position to the theoretical tangent and when this theoretical tangent is attained by the wheel the opposite end of the right-angled lever actuates a device for stopping and locking the feed of the grinding wheel by actuating the hydraulic positioning cylinder.
