Title: Line loss compensating circuit
Inventor: ICHIMURA AKIRA
IPC: H04B3/36
Filed: 1984-08-27
Abstract: PURPOSE:To increase the degree of compensation for line loss of a two-wire circuit by converting once a two-wire circuit into a four-wire circuit at both ends of the two-wire circuit and then converting again the four-wire circuit into the two-wire circuit after separating and amplifying the ascending and descending signal information. CONSTITUTION:A speech transmission signal current given from a two-wire connection circuit 11 is converted into a four-wire form by a 4/2-wire converting circuit HYB51. The speech transmission side (ascending signal current) actuates a relay A55 via a speech transmission amplifier TA52, a rectifier circuit 54 and a contact (b), and a busy state is detected. Therefore an ascending signal is amplified by the TA52 up to a level equivalent to the line loss of a two 2-wire circuit 12 and sent to the circuit 12 via a capacitor 58 and a contact (a). A line loss compensating circuit 6 receives the ascending signal current from the circuit 12 via a contact (c) and an RA63 and transmits it to a two-wire connection circuit 13 after conversion into a two-wire form through a circuit HYB261. For a descending signal current, an amplifier TA62 amplifies an amount equivalent to the line loss of the circuit 12 according to the operation of the ascending signal current. The amplified descending signal current is transmitted to the circuit 11 via a line compensating circuit 5.

Filed: 1989-07-11
Abstract: PURPOSE:To prevent destruction caused by a trouble from being enlarged and the trouble from occurring again by detecting abnormal overheat on a specified spot in a copying machine, interrupting feed to all the circuits and mechanically locking a feed interrupting state. CONSTITUTION:When a smoke emitting detection signal is inputted from sensors 100a-100c, a control CPU 200 outputs a signal for interrupting the feed to all the circuits to a power source circuit 300 from an output port PO0, and the power source circuit 300 side interrupts the feed to all the circuits. Then, the feed interrupting state is mechanically locked, which is held after turning off a power source. Furthermore, the release of the locked state can be performed by operating an operation means such as a switch, etc. Thus, the destruction caused by the overheat is prevented from being enlarged and the trouble of overheat caused by an erroneous power-supply reapplying operation is prevented from occurring again.
