Title: Conduction angle control self-excited inverter
Inventor: SAKAMOTO YOSHINOBU
IPC: H02M3/338
Filed: 1989-09-28
Abstract: PURPOSE:To reduce the size of inverter by employing an N-type and a P-type MOSFETs as two elements for switching a DC power source alternately and connecting the drain of one MOSFET directly to the power supply while connecting the drain of the other MOSFET to the power supply through a capacitor. CONSTITUTION:Upon start of a self-exciting inverter 1, an N-type MOSFET 5A is turned ON while a P-type MOSFET 5B is turned OFF. A saturable reactor 7 is continuously applied with +Vsc voltage through an auxiliary winding 19 and it is short-circuited, upon saturation, to discharge the gate voltage of the FET 5A so as to turn OFF the FET 5a. Inductive energy in the input winding 2 charges a capacitor 27. Consequently, the polarities at the terminals of the input winding 2 and the saturable reactor 7 are inverted thus turning the FET 5B OFF. The reactor 7 is continuously applied with -Vsc voltage and it is short-circuited, upon saturation, to turn the FET 5B OFF while turn the FET 5A ON thus returning the energy in the capacitor 27 to the power supply.

CONSTITUTION:The A1 spray-coated layer 2 of 30-200mum thickness is formed on the outer circumferential surface of the end part of the straight tube of a cast iron tube 1 as cast by executing the spray coating of A1. Then, red oxide (powder of Fe2O3) which is slurried with water is coated or sprayed thereon to form the Fe2O3 layer 3 of 10-150mum thickness. This cast iron tube 1 is placed in a lateral turning furnace, and annealed, for example, at the temperature of 980 deg.C.

Abstract: PURPOSE:To perform a stable and efficient operation with a loop car having a long effective length by catching tuning points as a locus and controlling it without fixing it to one point in accordance with speeds on the inlet and outlet sides of a looper of a material to be worked. CONSTITUTION:The starting point of deceleration of the loop car is required in accordance with the inlet side speed of the looper 5 and the outlet side speed of the looper in the material 1 to be worked. When the loop car arrives at this starting point, the deceleration of the inlet side speed of the looper is started and the locus of the tuning points is required in sequence in accordance with the outlet side speed of the looper.
