Title: Printed wiring circuit board
Inventor: NINOMIYA JUNJI
IPC: C22C49/06
Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a printed wiring circuit board which can be made light in weight and high in mounting density. SOLUTION: The printed wiring circuit board includes a substrate 1 made of a carbon fiber reinforced aluminum alloy containing carbon fibers dispersed into an aluminum alloy matrix, an insulating film 2 provided on one side of the substrate 1, and a conductive film pattern 3 formed on the insulating film 2. Semiconductor elements 4 are mounted on the board. In this case, parts 5 of the substrate 1 on which the semiconductor elements 4 are mounted have a carbon fiber dispersion percentage higher than the other part thereof so that a thermal expansion coefficient of the semiconductor element mounted parts 5 is as low as that of the semiconductor element. Since the substrate 1 is made of a carbon fiber reinforced aluminum alloy, the substrate is light in weight.  Further, since the parts of the substrate 1 corresponding to the mounted positions of the semiconductor element 4 have a high carbon fiber dispersion percentage and have a thermal expansion coefficient as low as that of the semiconductor element destruction of the element 4 caused by a thermal expansion difference therebetween can be prevented and high density mounting thereof can be realized.

Title: Hard film excellent in wear resistance and oxidation resistance and high hardness member
Inventor: TOMARI HARUO
IPC: C23C26/00
Filed: 1994-04-27
Abstract: PURPOSE:To improve the wear resistance and oxidation resistance of a hard film by using a multiple compound of one or more kinds among the metallic elements of the group IVa, Va, and VIa elements of the periodic table, Si, and one or more elements among N, C, and B. CONSTITUTION:The atomic ratio of Si to the total atomic content of one or more metallic elements selected from the group consisting of the group IVa, Va, and VIa elements of the periodic table is regulated to 0.01-70%. When the atomic ratio of Si is less than 0.01%, the oxides in the hard film cannot be densified and oxidation resistance becomes insufficient. When the atomic ratio of Si exceeds 70%, the film is formed into amorphous state and hardness is reduced and, as a result, sufficient wear resistance cannot be obtained. A hard film can be formed on the surface of cutting tools, dies, etc., by a PVD method, an ion implantation method, etc., and the service lives of the tools and the dies can be prolonged.
