Title: Transmission line terminating equipment
Inventor: MIYAKOSHI TAKESHI
IPC: H04B3/02
Filed: 1988-06-24
Abstract: PURPOSE:To reduce noises entering from power supply wiring together with induced noised by providing a filter circuit in addition to a potential generation circuit and impedance matching circuit and giving characteristics for interrupting the frequency band of transmission signals to the filter circuit. CONSTITUTION:When the interrupted frequency of a filter circuit 12B is made sufficiently lower than the frequency band of transmission signals, the output impedance of the circuit 12B in the transmission signal band becomes the sum of resistors 12b12 and 12b22 irrespective of values of resistors 12a1 and 12a2 of a potential generation circuit 12A. Since the DC potential given to a transmission line 13 is given by dividing a supply voltage by means of resistors 12a1, 12b11, 12b12, 12c, 12b22, 12b21 and 12a2, a circuit constant can be fixed easily. Moreover, since unbalanced noised from the power supply wiring are absorbed by the filter circuit 12B, no noises are transmitted to the line 13 and, since the line is connected to a sufficiently low impedance against the ground, induced noises can also be suppressed to a small amplitude.

Title: Automatic pausing circuit
Inventor: OOTSUKI TAKAO
IPC: G11B15/02
Filed: 1982-09-08
Abstract: PURPOSE:To obtain a pausing circuit which pauses automatically just with a push of a sound record button, by turning on the 1st and 2nd switches while the sound record button is pushed and applying a pulse signal to the pausing circuit to make the circuit into a pause mode. CONSTITUTION:When a sound record button 1 is pushed, a negative pulse is applied to the input terminal of a control circuit 2. Then an H signal is generated at the output terminal of the circuit 2. A tape recorder 3 is set in a recording mode by applying the H signal. At the same time, the H signal turns on a switch 6, and simultaneously applied to a differentiating circuit 7 for differentiation, then the output turns on a switch 8. As a result, switches 6 and 8 are turned on a time. Then a negative pulse L is applied to the input terminal of a pausing circuit 5. Therefore, the output of the circuit 5 is set at H level and then applied to the tape recorder 3 to have a record pause mode. The output signals of circuits 2 and 5 are applied to the recorder 3 at a time. Thus the recorder 3 is set immediately in a record pause mode with a push of the button 1.
