Abstract: Active turn-off or disabling circuits respond to control signals from a control unit which defines the mode of operation of a receiver. In response to a designation of a standby mode of operation the active disabling unit actively disables a pulse width modulator, such as a switched pincushion correction circuit, to prevent pulses from being produced based upon an input of ringing signal. The ringing signal may be produced in a horizontal flyback transformer during a transition interval that follows a transition to standby mode of operation.

Abstract: A rotary reactor (20) having a cylindrical, horizontally-oriented chamber (22) lined with a refractory (38) for burning materials therein and a plurality of trough-like lifters (40), extending along the interior surface of the chamber, for lifting sand in the chamber as the chamber rotates includes a lifter assembly (52, 54) which provides a secure, long-wearing mounting mechanism for the lifters which minimizes the degradation of the attachment of the lifter by the intrusion of contaminants between the lifter and the refractory. The lifter assembly comprises a bolt (56) for attaching the lifter to the chamber, a split support cylinder (76) recessed into the refractory lining and coaxial with the bolt, a sleeve (58) extending through the chamber and refractory receiving the bolt and being coaxial with the support cylinder, an anchor plate (82) receiving the bolt and sleeve member therethrough and having an outer periphery substantially contiguous with an inner periphery of the sleeve member, a mounting plate (72) supported on the support cylinder and attached to the anchor plate, a retainer plate (90) attached to an inner surface of the lifter and receiving the bolt therethrough so that the bolt cams against the retainer plate, and a cap (96) covering and protecting an end of the bolt. In one embodiment, the assembly includes slots (98, 100) formed in lifter and retainer plate to allow movement of the lifter relative to the bolt resulting from thermal expansion. A cam plate (102) is slidably mounted within the slots and receives the bolt means, and a slide plate (106) covers the slots and cam plate to prevent fouling of the slots.

Abstract: An information recording and reproducing apparatus employs   a   magneto-optical   disk   including   a   main information recording area wherein plural pieces of main information can be recorded and a TOC area wherein control information related to each piece of main information can be  recorded.   When a  reproducing  operation  cannot  be performed from the TOC area, it is checked whether or not any pieces of control information exist, for example, by detecting  an  amplitude  of  a  reproduced  signal.   Or, whether or not a recording or reproducing function of the apparatus works properly may be checked by, for example, a method of test writing and reproduction.  As a  result, whether or not the magneto-optical disk is a blank disk can be accurately determined.  Further, when the disk is determined to be a blank disk,  distinctive information indicating a blank disk is recorded in a predetermined portion of the TOC area.   Thereafter,  upon loading the disk, the disk is promptly determined to be a blank disk.          On the other hand, when the disk is not determined to be a blank disk, at least a recording operation is inhibited, thereby eliminating a possibility of  destroying useful main information already recorded in the main information recording area.
