Title: Gate-turn-off thyristor and power converter using the same
Inventor: MATSUURA NOBUYOSHI
IPC: H01L29/74
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To easily manufacture a large capacity gate-turn-off(GTO) thyristor having a controllable current corresponding to the size of an element, by arranging inward leads returning to the center of a ring and an outward lead extending from the center to the outside of a package in such a way that they form an angle over a predetermined value with each other. SOLUTION: A peripheral gate contact terminal 15 is connected to a plurality of inward leads 21, which are gathered at the center and connected to an outward lead 22. The inward leads 21 is received in grooves 31 made in a cathode side Cu post 3, and the outward lead 22 is received in a cylindrical hole 33 made in the cathode side Cu post 3. The outward lead 22 and the inner leads 21 are arranged such that they form an angle of 20 degrees or more with each other to eliminate variations in inductance between a unit GTO near to the outward lead 22 and a unit GTO away from the outward lead 22. This can lessen current concentration generated when a large capacity GTO is turned off and can provide a controllable current corresponding to the size of an element.

Title: Needle valve driving device for pelton wheel
Inventor: INAGAKI TAIZOU
IPC: F16K31/04
Filed: 1984-02-20
Abstract: PURPOSE:To drive a needle valve without using an oil pressure, by a method wherein rotary movement of a gear driven by an electric motor and decelerated by a gear train is converted into linear reciprocating movement. CONSTITUTION:A gear train 14 consists of a first step driving gear 17, secured to a rotary shaft 16 of an electric motor 13 and rotated together with the motor, an intermediate gear 18, geared with a gear 17 to produce a given moderating ratio, and a final step driven gear 19. A converting means 15 comprises a screw rod 22 formed on the needle valve side of a spindle 20, and a nut 23 engaging with the screw part of the screw rod. Since the nut 23 is axially reciprocated through forward and reverse rotation of the screw rod 22, the rotary movement is converted into reciprocating movement in a linear direction through forward and reverse rotation of the electric motor 13, and this causes opening and closing of a needle valve.

IPC: E02D1/00
Filed: 1981-03-04
Abstract: PURPOSE: To finish treatment work after a penetration test only by a simple work without the drawing-out work of penetrated rod by a method in which out of the penetration rod and a joint rod driven underground, only the joint rod projecting from the ground's surface is removed by leaving the penetration rod intact under the ground.  
     CONSTITUTION: A penetration rod 1 is penetrated underground by dropping a weight 2a onto the rod 1 from a given distance as shown by an imaginary line. Then, a joint rod 1a is connected with the upper end of the rob 1 and the dropping operation of the said weight 2a is repeated for performing soil survey. After the completion of the soil survey, a penetration tester on the ground's surface is removed by leaving the penetration rod 1 and the joint rod 1a driven underground intact, and then the rod 1a projecting from the ground's surface is drawn out. Thus, since the penetration rod once used is left under the ground, penetration test can be exactly performed by using new penetration rods in any case.
