Abstract: A facsimile device which stores the data of the incoming level of a training signal in the incoming mode, and judges this to be the starting point for receiving the picture signal when the incoming level after transferring the CFR signal is larger than the threshold level which is lower than the abovementioned stored incoming level by a predetermined value. The picture signal can be received with stability even when a circuit echo occurs.

Abstract: A video tape recorder comprising two video decks; one assigned to recording video signals and the other assigned to playing them back immediately in order to check if the recording has been made properly to create a means by which viewers never fail to record.

Abstract: A device for selecting a TV channel in which the names and numbers of the stations are stored in memory in advance. The user selects a program by pressing a key chosen by number or by character. In response to the user's choice of an initial letter, the device displays, individually or in a list, the whole name of the program or station so the user can choose a desired one.

Abstract: Disclosed is a TV and VTR compound set in which a holder for supporting TV's printed circuit board in a space between the inside surface of the cabinet and TV's Braun tube vertically and TV's flyback transformer laterally is newly introduced, by which holder TV's flyback transformer and VTR's picture recording and reproducing head come to be placed apart from each other at the farthest distance possible in the cabinet and the transformer's noise comes to be prevented from interfering with the head and by which not only is TV's transformer's noise prevent from entering VTR's head as mentioned above but also the dimension of the cabinet can be made smaller than that of the conventional cabinet similarly housing TV and VTR and the production cost of the set can be reduced.

Abstract: A synchronous circuit useful for video games and the like is employed to coincide an external video signal in synchronization with an internally-generated video signal. The external signal may be produced by a laser disc playing device, or by other devices. The synchronous circuit reduces the time period for synchronization and eliminates jitter on the external synchronizing signal. A flip-flop circuit element is employed, together with a horizontal synchronizing signal counter having a cycle period somewhat smaller than that of an external horizontal synchronizing signal. The flip-flop circuit element is connected at one input terminal to an output stage of a counter output through a reset line.

Abstract: A stereophonic sound producing apparatus employs four speakers, a background-sound input signal and input-sound signals, to provide an on-the-spot "live action" feeling. The sounds are combined and varied such that a sound such as an artillery shell has a simulated sound and an aurally simulated movement discernible to a human ear. Mixers and attenuators are used, so that a digital "1" or "0" signal serves to operate the on-the-spot "live action" sound effects. A cockpit is provided, together with a video display. A video signal and/or background sound signal is provided by a digitally encoded disk.
