Title: Hydraulic power transmission coupling
Inventor: SUZUKI SATORU
IPC: F16D31/02
Filed: 1991-08-06
Abstract: PURPOSE:To prevent an accumulator piston from jumping out, by rotating plural pieces of weights together with a coupling, converting centrifugal force, acting on these weights, into axial force, and making the accumulator piston so as to press it in the coupling internal direction, in a transmission coupling for car driving force distribution. CONSTITUTION:Plural pieces of weights 24 are housed in an accumulator piston 23, thereby constituting them to be solidly rotated together with a coupling and to be freely shifted in the radial direction. In brief, an incline part 25, housing these weights 24, is formed in the accumulator piston 23, preventing any lost motion in each weight 24 by means of a spring 27, and then they are housed. When these weights 24 are rotated together with the coupling, centrifugal force acting on these weights 24 is converted into axial force by the incline part 25 and a cover 26, thus the accumulator piston 23 is pressed to the inner direction of the coupling.

Title: Thyristor
Inventor: WADA KAZUHISA
IPC: H01L29/74
Filed: 1983-10-20
Abstract: PURPOSE:To increase the dv/dt strength and reduce the gate ignition current by forming an island-form region similar to an emitter region on the under-side of a gate electrode at a distance farther from the emitter region. CONSTITUTION:Separately from the N<+> emitter layer 4, the N<+> island-form region 9 is provided under the gate electrode 5 in L form beneath its side opposed to the emitter layer 4 and the opposite side. Since this region 9 is in the state of being short-circuited by the gate electrode, injection due to gate forward bias does not generate in the neighborhood of the region 9, and the gate ignition current concentrates toward the A region farthest from a cathode short part 7 as shown by arrows 10. As a result, gate ignition can be produced by a small gate current independently of the dv/dt strength. The intensity of this gate ignition current is exclusively determined by the degree of restriction of flow direction, according to the opening degree of the region 9.
