Title: Steel pipe cutting machine
Inventor: YONEYAMA TOSHIJI
IPC: E02D9/04
Filed: 1977-10-19
Abstract: PURPOSE: To improve the balance of operation of a cutting machine by providing a plurality of cutters in the circumferential portion of a machine body which is divided into a plurality of parts at the same angle via the axis of the machine body, so that one of the cutters in operation absorbs the reactional force of another.  
     CONSTITUTION: A cutter 4 is forced out by a piston 5 to press the inner surface of a steel pipe as the cutter 4 is rotated in a desired direction in a plane at right angles to the axis of a machine body 2. Since the cutter 4 is rotatably connected to a cutter arm 3, the cutter 4 comes into rolling contact with the inner surface of the steel pipe and is moved like a planet. When an actuating member 11 is constantly urged in the upward direction by a drive source 10, the cutter 4 is gradually pushed in the outward direction to cut into the wall of the steel pipe from the inner surface thereof. Since the actuating member 11 is of a conical shape, a plurality of cutters 4 on the circumferential portion of the machine body 2 divided into a plurality of parts at the same angle via the axis thereof by a cutter arm bracket 19 are forced out in the outward direction under the same pressure.

Filed: 1978-10-12
Abstract: PURPOSE:To provide a semiconductor device which is miniaturized in size by arranging a member of controlling the di/dt values on the periphery of a semiconductor element and yet inside a cooling wind tunnel so that both the control member and the semiconductor element are cooled at the same time within the common cooling device wind tunnel.

A cooling fin 4 is fitted to both electrodes of the element 1, with the iron core 2 provided between the periphery of the element 1 and the cooling fin 4. The thus formed composite is placed within a wind tunnel 9 to be cooled, using a cooling fan 6. The iron core tends to become exothermic by hysteresis loss, but since it is situated near to the element 1 within the wind tunnel 9, no extra cooling means to be used exclusively for cooling the iron core may be required any longer. This is why the semiconductor device can be made smaller sized.
