Patent JP-S60220604-A (JP)
Title: Oscillator
Inventor: SAITOU KENJI
IPC: H03B5/32
Filed: 1984-04-17
Abstract: PURPOSE:To prevent mixture of the noise from an output terminal to obtain a stable oscillation output by providing a cylindrical earth terminal around the output terminal. CONSTITUTION:A cylindrical earth terminal 8 is provided around an output terminal 2 and an optional gap apart from the output terminal 2. By the presence of this earth terminal 8, influences of variance of the voltage and the current applied to a conductor 7 forming a circuit pattern are not transmitted to the output terminal 2. Therefore, mixture of the noise from the output terminal 2 is prevented. That is, electrostatical and electromagnetic coupling between the output terminal 2 and the conductor 7 is not caused, and influences from an external wiring or the like are avoided similarly. Consequently, a stable oscillation output is obtained.

Title: System for confirming termination of data transfer using tone signal
Inventor: KAKEHI HAJIME
IPC: H04M11/06
Filed: 1980-06-12
Abstract: PURPOSE:To ensure a confirmation for the termination of data transfer at the incoming side, by consecutively transmitting a tone signal along with an originating request information from the originating side and cutting off the tone signal after the end of data transfer. CONSTITUTION:A data transmission control part 20 transmits a dial information to connect the center side to the terminal side, and then switches a circuit switch relay 36 from the originating/incoming side to the data transmission side. Then the part 20 starts a tone generating circuit 24. Thus the tone signal plus the FM-modulated polling signal are transmitted to the terminal side via a transformer 32. The data signal, if transmitted from the terminal side, is supplied to a demodulating circuit 28. This data is supplied to a central processor via the part 20 to receive an error checking. When no error is detected, the relay 36 is switched to the originating/ incoming side. Thus the tone signal is never transmitted to the terminal side, and  the end of polling can be known at the terminal side.
