    摘要： A mechanical heart valve apparatus includes a loop-shaped frame defining a valve opening and formed with a pair of transverse slot units and a pair of longitudinal slots; and a pair of valve plates mounted on the loop-shaped frame. Each of the valve plates includes a pair of first studs that are slidably and respectively inserted into the transverse slot units, and a second stud that is slidably inserted into a respective one of the longitudinal slots. The valve plates are pivoted to each other so as to be rotatable relative to each other between a closed position, in which the second studs are disposed adjacent to upper ends of the longitudinal slots, and an opening position, in which the second studs are disposed adjacent to lower ends of the longitudinal slots.

    摘要： A rolling ball separator structure of a linear drive member includes multiple separators mounted between the multiple rolling balls and each having a body and an outer ring structure. Thus, the body may be deformed elastically, thereby preventing the multiple separators from interfering with the return face of the rolling path during the returning process of the rolling balls, and thereby absorbing the gap variation of the uneven force during the returning process of the rolling balls, and the outer ring structure may maintain the relative position of the rolling balls, so that the rolling balls will not collide directly during the returning process.

    摘要： The present invention is to provide a slide track structure of a linear platform, wherein the center of gravity of the slide track structure of the linear platform may be lowered. In addition, the outer edge of the upper end of the U-shaped guide track is formed with an inclined face or a smooth arc-shaped face, thereby capable of producing better structural stiffness, saving material, and decreasing weight. Thus, the slide track structure of the linear platform of the present invention can increase the structural stiffness, save material, and decrease the entire weight.

    摘要： A cemented tungsten carbide-based material includes: a cemented tungsten carbide substrate having a chromized layer that contains a tungsten carbide and a chromium carbide; and a diamond film formed on said chromized layer. A method for making the cemented tungsten carbide-based material involves subjecting a cemented tungsten carbide substrate to chromization so as to form the cemented tungsten carbide substrate with a chromized layer that contains a tungsten carbide and a chromium carbide; and forming a diamond film on the chromized layer.
