Title: Reference signal generating circuit device
Inventor: NISHIYAMA KIYOHARU
IPC: H04N5/782
Filed: 1989-07-31
Abstract: PURPOSE:To form a reference signal generating circuit device with a few components and simple circuit constitution by resetting a reference signal of the same period as that of a vertical synchronizing signal and sending the reference signal again based on a signal sent from a count section and a waveform shaping circuit. CONSTITUTION:For example, 4 vertical synchronizing signals or over are missing, a counter 7 changes an output signal level into an H level from an L level so far when the count reaches 4 or over. Then since a signal of an H level is fed to one input of an AND circuit 3, a 1st vertical synchronizing signal after the missing is fed to a waveform shaping circuit 2. When a pulse signal a3 is sent from the waveform shaping circuit 2, the AND circuit 3 sends a signal of an H level to a pulse generating circuit 4. Then the pulse generating circuit 4 resets a reference signal sent in self-running and sends a reference signal of the same period as that of the vertical synchronizing signal again newly synchronously with the pulse signal a3.

Filed: 1999-07-13
Abstract: PROBLEM TO BE SOLVED: To provide a communication terminal that inexpensively transmits information to a transmission destination without tracing an undesirable path even in the case of transmitting the information via a communication terminal having a relay function. SOLUTION: A main control section 1 stores the least expensive routing to a connection path information table 24 according to connection information sent from other communication terminal in advance. In the case of transmitting information to a transmission destination, the least expensive routing is used in the connection path information table 24 to select a relay path. In this case, the importance of the transmitted information or the like is taken into account and in the case of transmitting, e.g. secret information, a path such as the Internet where leakage of secrecy may take place is avoided through the selection of a relay path. Then the information with information relating to the relay path and denoting whether or not he information is secret added thereto is transmitted to a succeeding communication terminal having a relay function.
