Title: Tape recorder device
Inventor: FURUKAWA HIROSHI
IPC: G11B5/027
Filed: 1986-02-14
Abstract: PURPOSE:To prevent the oscillation or the unstable state that is caused by the bias leakage to a reproduction amplifier for a tape recorder device storing the transports A and B of a magnetic tape, by using the reproduction amplifier also to both transports A and B and cutting off the loop between the regenerative amplifier and a recording amplifier of the recording side during a dubbing mode. CONSTITUTION:The reproduced signal supplied to a recording amplifier A2 from a reproducing head PH for amplification and then recorded on a magnetic tape loaded to a transport A by a recording/reproducing head RPH via a transistor TRQ15. In such a case, the bias leaked out via an OFF resistance of a TRQ14 is not emerged at the input of a regenerative amplifier A1 since a TRQ13 of a selection circuit 10 is kept under an ON state. Thus no loop is formed between both amplifiers A1 and A2 and these amplifiers are separated completely from each other regardless of the bias oscillation level of a bias oscillation circuit 12. In such a way, the adverse influence of oscillation, etc. due to the bias leakage is prevented.

IPC: H04L29/08
Filed: 1983-03-01
Abstract: PURPOSE:To attain sure communication of a document by inhibiting the communication if an error occurs in terminal identification information. CONSTITUTION:When a transmission request is received from a system control section 8, terminal identification information TID stored in a nonvolatile memory 57 in a communication control section CCU5 is read. Further, bytes from the 1st to the 24 bytes are added by sum check calculation so as to check whether or not a low-order 8-bit of the result of addition is coincident with an error discriminating data stored in the memory 57. That is, whether or not the TID has an error is discriminated. When an error exists from the result, a TID error response is transmitted to a system control section 8 and the transmission is rejected. When the result of discrimination has no error, the transmission processing of document is started. After a dial number of an opposite party and a transmitted document are received from the system control section 8 and the format conversion of the document is attained, the line is connected and the document is transmitted and the result of transmission is transmitted to the system control section 8.

Filed: 1995-02-21
Abstract: PURPOSE: To improve the speech quality by selecting a circuit component of a dummy circuit so that its current flowing at its conduction is almost equal to a current flowing to the light emitting diode when it is conductive thereby preventing noise production. CONSTITUTION: A dummy circuit 7 is made up of an NPN transistor(TR) 71 and a resistor 72, an emitter of the TR 71 connects to a control terminal 4 being an input terminal of an LED control signal and its collector connects to a DC power supply via the resistor 72. Since a current flowing to a digital TR circuit 3 and an LED 5 when the LED 5 is lighted is usually 10mA, a primary current of a transformer 1 is almost unchanged by selecting the TR 71 and the resistor 72 so that the current flowing to the dummy circuit 7 when the LED 5 goes off is nearly 10mA even when the LED control signal is switched from its high level into a low level or vice versa, and then no noise is produced on a voice signal line.
