IPC: H04N5/08
Filed: 1985-06-29
Abstract: PURPOSE:To assure a separation of synchronous signals even when sag of vertical scanning cycle incidentally occur in an image detecting output by providing a slice level variable means which make slice levels of a synchronizing and separator circuit variable. CONSTITUTION:The slice level variable means is composed of a differential amp circuit 13 of a synchronous separator 11, peak detecting circuits 14 and 17, a reverse amplifier circuit 16, an integration circuit 15, a single monostable multivibrator 18 and the like. When a vertical synchronous signal a composite in video signal which is an output of an image detecting circuit 4 occur the sag and direct current level becomes larger during vertical synchronous period, an emitter potential of transistor Q1 of synchronous separator circuits 12 rises and allows the transistor Q2 to repeat ON and OFF and then outputs of the peak detecting circuits 14 to develop ripples. The ripple current is detected and rectified by the peak detecting circuit 17 and allow the transistor Q6 to rise a base potential. Then the transistor Q6 becomes to be ON during a vertical blanking period and permit a base bias of the transistor Q1 to be lowered and also the synchronous signal to be separated from the video signals.

Filed: 1993-06-16
Abstract: PURPOSE: To provide advanced priority having a recovery function onto a serial communication link and to obtain the method and device for an enhanced HDLCMAC layer protocol. CONSTITUTION: In a data/audio/multimedia mixture communication system, a protocol is defined to realize transmission reception of a high priority real time traffic on a low-speed digital communication link, by inserting a high priority traffic in a low priority/non-real time traffic. A high priority packet is transmitted, without causing a delay by prefetching a low priority packet. The low priority non-real time packet is buffered during a prefetch and its transmission is automatically recovered after the end of the high priority packet transmission. When a communication link is activated, a protocol is defined in the system, so that the communication system exchanges link capacity definition information with the communication link to process the high priority real time packet and the system permits the transmission method of the high priority traffic on the communication link.  A packet, including a header 10B and data 10C, is identified by a flag.

Title: Interrupting system
Inventor: KATOU KEIICHI
IPC: G06F3/06
Filed: 1979-11-08
Abstract: PURPOSE: To prevent the state under which the control device is not actuated normally for a long time due to the fault of the control device and the signal line, by applying the signals of different cycles to the signal lines which give a connection between the control devices and then using one of the signals for the interruption signal.  
     CONSTITUTION: The signals e 1  and e 2  are applied at all times to the multiplexer 4 through the input signal lines 5 and 6, and the signal e 1  is transmitted in the normal state to the signal line 3 via the multiplexer 4. In case when an interruption request is given, the signal e 2  is transmitted for a fixed time by the control of the FF7. When the control device 2 receives the signal e 1  via the signal line 3, the output of the comparator 9 turns to the signal e 5  (dotted line). Then this signal e 5  is monitored to detect the disconnection or the like of the line 3. In case when an interruption request is given, the output of the comparator 10 turns to the signal e 7 . Thus the interruption request can be accepted. Thus the state under which the control device is not actuated normally for a long time can be prevented.
