PURPOSE:To align and support many objects to be soldered by providing plural sets of 2-piece set of lower steel wires extended between frame bodies, and 2- piece set of upper steel wires which are set at one end of the frame bodies and are supported at the other end by freely vertically movable gate bodies in the upper part of the former steel wires and providing insertion ports for the objects to be soldered to the frame bodies by facing the gate bodies. CONSTITUTION:Frame bodies 57 detained to a conveying holder 29 of a soldering line, plural sets of 2-piece set of lower steel wires 59 which are extended between the bodies 57 and support the lower side of objects 58 to be soldered and 2-piece set of upper steel wires 60 which are disposed in parallel with the upper part of the respective sets of the lower wires 59 along both side surfaces of the objects 58 and are set at one end to the bodies 57 are provided. The other ends of the respective sets of the wires 60 are supported by freely vertically movable gate bodies 61 and insertion ports 62 for the objects 58 are provided to the bodies 57 by facing the bodies 51. Thus the objects 58 are aligned and supported by four pieces of the steel wires.

PURPOSE:To reliably turn OFF a thyristor without damage by providing a gamma- limiter which produces a pulse at the prescribed maximum delay phase angle and a pulse lock circuit for interrupting the normal firing control pulse. CONSTITUTION:A firing control pulse controlled in phase by a phase control unit 21 is inputted to gamma-limiter 22 corresponding to the necessary reactor current to compensate the generated reactive power in a reactive power control unit 20 of a controller 19. This limiter 22 always outputs a pulse at the maximum delay phase angle predetermined even when the firing control pulse phase control signal is maximum throttle command. A pulse lock circuit 23 operates corresponding to the forcible firing signal, and interrupts the firing control pulse transmitted to the thyristor of reverse phase to the thyristor, to which the forward overvoltage is applied at least by one cycle.

Controller for thyristor

PURPOSE:To increase the video quality of reproduction, even if noise is intruded, by performing the request of retransmission and rewriting the part causing error for the reception side video memory content, through the error detection at the reception side.
