Title: Speech communication channel switching method and tdma terminal for realizing the method
Inventor: YASUDA SHUHEI
IPC: H04W72/04
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To reduce interference avoidance time at switching of a speech communication channel by making a slave station send a link establishment request to a slot of an up link of a control channel which corresponds to a slot of down link of a control channel that is received at all times, as soon as it detects an interference wave and to resume speech communication with a slot of a new speech communication channel that has been allocated by a base station. SOLUTION: A base station searches for a speech communication channel Tch, that is unused and sends a link channel allocation to a slot of a control channel Cch, and a slave station 1 starts communication with a slot of an allocated Tch. When the station 1 detects an interface wave in the slot of the Tch during speech communication, it sends a link channel establishment request that is a speech communication request to the slot of the Cch. Here, the station 1 is provided with transmitting and receiving parts 11b to 13b for the Cch, independently of transmitting and receiving parts 11a to 13a for the Tch. Consequently, the Tch does not have to be released, and time in silent state at switching of a slot of the Tch can be curtailed.

Title: Chrominance signal processing circuit for magnetic recording and reproducing device
Inventor: ANDO YASUNORI
IPC: H04N9/89
Filed: 1991-12-26
Abstract: PURPOSE:To reduce crosscut noise by preventing the malfunction of a phase control means caused by the lost signals by preventing cross talk from being removed from chrominance signals when the inter-channel cross talk quantity of the chrominance signals is small. CONSTITUTION:Concerning the chrominance signals whose frequency is converted by a frequency converter 1, only the cross talk component is extracted by a Y comb line filter 7, and a DC voltage in proportion to the cross talk quantity is generated by a detection circuit 8. Since the output voltage of the detection circuit 8 is made higher than a prescribed value when the cross talk quantity is large, according to the output of a low potential from a comparator circuit 9, a switch circuit 6 transmits the chrominance signals passed through a C comb line filter 2 to a phase control circuit 4. On the other hand, when the cross talk quantity is a little, the output voltage of the detection circuit 8 is made lower than the prescribed value, and the chrominance signals before passing through the C comb line filter 2 are transmitted to the phase control circuit 4. Therefore, a phase change caused by the cross talk component is reduced for the chrominance signals to be transmitted, and an error voltage generated at the phase control circuit 4 is reduced.
