Title: Slicing method
Inventor: YASUNAGA NOBUO
IPC: B28D1/22
Filed: 1990-04-18
Abstract: PURPOSE:To permit the ingot having a larger diameter to be cut with a blade of the conventional size by a method wherein the ingot is sliced successively in different directions. CONSTITUTION:An ingot 1 is first fed in a first radial direction of a blade to an ingot fixing stand while being cut, preferably not more than one half its entire size, then moved back to the center O of the blade and thereafter moved in a second radial direction of the blade approximately perpendicular to the first direction thereof to cut off the remainder of the ingot. Preferably, the ingot is first cut in the first radial direction, for example, a direction 3 at an angle of 45 deg. to a perpendicular line of the ingot fixing stand 2 penetrating to a point 5 of intersection of the perpendicular line 4 passing through the center of the ingot 1 and the ingot fixing stand 2 and then in the second radial direction 6 at an angle of 90 deg.+ or -20 deg. to the first radial direction, thereby completing the cutting of the ingot 1 in its entirety. The maximum cutting amount required at this time can be made much smaller than that required for the entire cutting by feeding in only the first radial direction.

Title: Method of starting motor dynamo
Inventor: NAGASE NAOAKI
IPC: H02P1/50
Filed: 1979-08-08
Abstract: PURPOSE:To reduce an influence upon power lines with which a motor dynamo is connected in parallel, by controlling the gate phases of antiparallel thyristors, which are connected to a starting bus, to regulate the voltage and current of the motor dynamo only in its starting. CONSTITUTION:To start the motor dynamo 1, a generation side phase change-over disconnecting switch 6 is opened and a pump-up side phase change-over disconnecting switch 7 is closed and a starting circuit breaker 8 is thereafter closed. As a result, the intermediate tap voltage of a main transformer 4 is applied to antiparallel thyristors 14. When a starting instruction A is applied to a controller 20, the output AC voltage of the antiparallel thyristors 14 varies linearly from zero to the maximum for t1 seconds. An instruction for closing a switch 15 for short-circuiting the antiparallel thyristors 14 is applied from a closing instruction circuit 23 after t1 seconds since the reception of the starting instruction A. A field circuit breaker 11 and a circuit breaker 5 for parallel connection are then closed.
