摘要： A ratchet wrench including a fixed jaw and a movable jaw attached to a body of the ratchet wrench and having V-shaped nut gripping portions opposing each other. The fixed jaw is pivoted to a forward end portion of the body and biased to rotate toward the movable jaw by a spring. An adjusting nut is provided rotatably about a longitudinal center axis of the body, and an adjusting screw rod is threaded into the adjusting nut so that it is movable back and forth along the longitudinal center axis of the body by rotating the adjusting nut in one direction or the other. The movable jaw is pivoted at a rear end portion thereof to the adjusting screw rod by a guide pin which is guided along a longitudinal slot provided in the body and, the movable jaw is biased to rotate toward the fixed jaw by a spring provided between the movable jaw and the adjusting screw rod. A pivot point between the movable jaw and the adjusting screw rod is positioned on a straight line passing through apexes of the V-shaped nut gripping portions of the movable jaw and the fixed jaw upon gripping a nut therebetween.

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 device for mounting a lamp on a lamp mount includes an engagement spring made of a spring steel sheet in the form of a leaf spring having a substantially elliptical shape. The engagement spring is configured such that it extends at a right angle relative to the axis of a lamp socket, and moreover, it exhibits a line symmetry relative to two lines extending on a common plane at a right angle relative to each other. The common plane extends at a right angle relative to the axis of the lamp socket. The engagement spring includes an opposing pair of depressing portions and an opposing pair of arm-shaped engagement portions. The depressing portions extend in parallel with one of the two lines while maintaining a line symmetry relative to one of the two lines. The engagement portions are arranged in a spaced relationship while maintaining a line symmetry relative to other one of the two lines. When the engagement spring is placed in position on the upper surface of a lamp socket inserted through a socket insert hole, a uniform resilient depressing force is imparted to the lamp socket from the engagement spring so as to firmly hold the lamp socket on the lamp mount.

摘要： A variable-displacement compressor includes a wobble member for driving a pistons, and a rotation member for wobbling the wobbling member, a first support portion for supporting a wobbling member in such a manner that the angle of wobbling of the wobbling member is variable, and a second support portion for supporting said rotation member in such a manner that the angle of tilt of said rotation member relative to a main shaft is variable. With this construction, unbalanced inertia forces can be reduced greatly, thereby providing the variable-displacement compressor which produces less vibrations and noises.
