Abstract: A high-power thyristor module includes a housing configured with an inner receiving space, and a thyristor unit disposed in the inner receiving space in the housing and including a mounting frame, and a plurality of high-power thyristors mounted on the mounting frame. Each thyristor has a gate. The mounting frame includes a dielectric top plate disposed on a top side of the housing, and a plurality of electrodes mounted on the top plate so that the electrodes are exposed outwardly of the housing, and coupled respectively to the gates of the thyristors. Cooling oil is contained in the inner receiving space so that the thyristors are submerged thereby.

Abstract: The present invention provides an impingement sprinkler with adjustable outflow angle. The invention includes a main body, at a lower side of which there is an inflow tube coupling end, and at upper side of which there is an upper frame. An outlet coupling portion is arranged at the lower flange close to the upper frame. A rotating member is arranged onto the upper frame of the main body; and an adjustable outflow head is assembled onto the outlet coupling portion of the main body, allowing the outflow angle to be freely adjusted. It is possible to adjust freely the sprinkling angle with the adjustable outflow head.

Abstract: This invention provides an electric generating system with energy transfer device for accumulating and transferring the compressed medium to produce driving force for generating electric power. Once the electric generator start generating electric power, the driving force can be transmitted simultaneously to a medium compressor to compress the medium in the pressure reservoir for accumulating pressure. The compressed medium can be released automatically and properly to push the fan wheel to rotate by a pressure release valve when the driving force of the electric generator is stopped so as to provide extra driving force to operate the electric generator continuously.

Abstract: A computer key includes a socket member which confines a receiving space therein and which has a top wall that is provided with a through hole, a resilient biasing member which is disposed inside the receiving space of the socket member, and a support member which has an upright tubular portion and a flange portion that projects radially outward from an intermediate part of the tubular portion and that is in sliding contact with an inner wall surface of the socket member. The support member is provided inside the receiving space of the socket member such that the tubular portion extends through the through hole of the socket member. The tubular portion has a bottom end which rests on top of the biasing member. The biasing member urges the support member upward to a normal unpressed key condition. A push button is secured on top of the support member.
