Abstract: Metal foil base material placed on lower blade is first restricted under pressure by lower blade and pad and then cut by a shearing action based on an engagement of lower blade side cutting edge and upper blade side cutting edge. Resin face sheets are fixed to the top surface of lower blade and the pressing surface of pad, the face sheets having a larger friction coefficient than that of these surfaces. By frictional forces imparted by face sheets, metal foil base material is prevented from being dragged and moved by the pressing force of the upper blade prior to cutting. Consequently, the occurrence of “burr”, “roll-up”, and so forth is eliminated thereby ensuring a good cutting quality.

Abstract: A connecting rod of an internal combustion engine, comprising a connecting beam section serving as a main body of the connecting rod. Big and small ends are located at the opposite ends of the connecting beam section. A first joining section is located between the connecting beam section and the big end to connect the connecting beam section and the big end. A second joining section is located between the connecting beam section and the small end to connect the connecting beam section and the small end. In this connecting rod, each of the first and second joining sections gradually and continuously decreases in cross sectional area toward the connecting beam section and has a strength distribution in which a strength increases with a decrease in the cross sectional area.

Abstract: A method of producing a material having a layer of ceramic as a first component, a layer of a metal as a second component and an intermediate layer lying between said layers and including said first and second components in continuous gradient ratios so that the properties of the material may change continuous, including a step of forming said intermediate layer by igniting a powder mixture of metallic and nonmetallic constitutive elements of said ceramic component and said metal component so as to cause a synthetic reaction in the powder mixture.
