Title: Device for conveying billet from billet heater
Inventor: OKAYAMA SAKAE
IPC: F27B9/22
Filed: 1984-09-20
Abstract: PURPOSE:To enable a fixed quantity of billets to be conveyed surely and continuously by connecting a chuter to an outlet of the billets in the inclinable manner and by making a billet stopper which is provided at the end of a chuter controllable of carrying out. CONSTITUTION:High-temp. billets 2 heated by an induction heating coil 1 are conveyed continuously on a carrying base 3, and moved onto a chuter 4 in a fixed quantity. At this time, by projecting a stopper 8 in the chuter 4, a fixed quantity of billets 2 is moved onto the chuter 4. Then the billet 2 at the end of the carrying base 3 is pressed down by a piston-type stopper 5. After that, the chuter 4 is made inclined so as to be connected to a fixed chuter 7 and the stopper 8 is released. Thus, the billets 2 on the chuter 4 slide down smoothly and continuously with their own-weight, and can be surely conveyed out of the fixed chuter 7.

IPC: H02P21/05
Filed: 1986-08-22
Abstract: PURPOSE:To get rid of resonance with a load in forming a superb follow-up characteristic, by adding the output of a speed control amplifier to that of a speed command change rate arithmetic circuit as a torque current command. CONSTITUTION:A speed command change rate arithmetic circuit 19 constitutes an open loop control system, inputs a speed command Ns from a speed pattern generator 1 and performs the operation by multiplying its rate of change dNs/dt by a coefficient K. For this coefficient K the torque is worked out which is decided by the rate of change in the speed command Ns and by the load inertial force GD<2>, setting it as a torque generating coefficient so as to become nearly this control amount of torque as required. The speed command Ns is matched with a speed detection signal omegan by a speed control amplifier 2 and the proportional-plus-integral operation is performed. The output of this speed amplifier 2 is added to that of a speed command changing rate arithmetic circuit 19 to make a torque current command IT.

Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To surely end laser irradiation through the turning off of a switch even if a built-in component of a switch unit has failed during the irradiation of a laser beam while a continuous application mode is set. SOLUTION: First and second switches 11 and 12 are electrically connected in series with each other by a signal line 18 and provided side by side.
