摘要： As the semiconductor chip is large-sized, highly integrated and speeded up, it becomes difficult to pack the semiconductor chip together with leads in a package. In view of this difficulty, there has been adopted the package structure called the "Lead-On-Chip" or "Chip-On-Lead" structure in which the semiconductor and the leads are stacked and packed. In the package of this structure, according to the present invention, the gap between the leading end portions of the inner leads and the semiconductor chip is made wider than that between the inner lead portions except the leading end portions and the semiconductor chip thereby to reduce the stray capacity, to improve the signal transmission rate and to reduce the electrical noises.

摘要： A ball screw in a continuously variable speed transmission has an axially immovable pulley half (2) and axially movable pulley half (3) both mounted on a rotary shaft (4). The axially movable pulley half (3) is moved by a ball screw (20) so as to infinitely vary the belt wrapping radius and thus the transmission speed. A nut (22), forming one part of the ball screw (20), is immovably secured in both axial and rotational directions. A screw shaft (21), forming the other part of the ball screw (20), is movable in both axial and rotational directions. The screw shaft 21 is connected to the axially movable pulley half (3). The axially movable pulley half (3) is axially moved by rotating the screw shaft (21).

摘要： As the semiconductor chip is large-sized, highly integrated and speeded up, it becomes difficult to pack the semiconductor chip together with leads in a package. In view of this difficulty, there has been adopted the package structure called the “Lead-On-Chip” or “Chip-On-Lead” structure in which the semiconductor and the leads are stacked and packed. In the package of this structure, according to the present invention, the gap between the leading end portions of the inner leads and the semiconductor chip is made wider than that between the inner lead portions except the leading end portions and the semiconductor chip thereby to reduce the stray capacity, to improve the signal transmission rate and to reduce the electrical noises.

摘要： In a link plate for use in a power transmission chain driven to run while a side edge of the link plate is in sliding contact with a shoe surface a chain guide member, the side edge of the link plate has a pair of contact portions near opposite longitudinal ends thereof for sliding contact with the shoe surface, and a recessed central portion extending between the contact portions. The recessed central portion together with the shoe surface forms a space which is capable of collecting and holding lubricating oil when the contact portions are in sliding contact with the shoe surface. As the link plate slides on the shoe surface, the lubricating oil trapped inside the space gradually enters between the contact portions and the shoe surface to thereby form an oil film. With this oil film, friction between the link plate and the shoe surface is reduced, leading to reduction of running resistance of the power transmission chain.
