Title: Data transfer unit
Inventor: HASHIGUCHI TATSUROU
IPC: G06F11/00
Filed: 1979-05-24
Abstract: PURPOSE: To increase the efficiency of data transfer, by constituting the unit with data buffer memory, registers, comparison circuit, FFs and failure detection circuit.  
     CONSTITUTION: A data buffer memory 1 is a memory temporarily storing the data and the area assigned corresponding to the input and output channel is accessed with the content of a register 2 storing the channel number under operation at present. A failure detection circuit 7 detects a failure of the memory 1 depending on the presence of error in output data. The failure of the memory 1 detected at the circuit 7 sets FF6 to "1", indicating the production of failure. Simultaneously, the channel number of the register 2 is set to the failure production channel number register. A comparison circuit 4 compares the channel number of the register 2 with the failure production channel number of a register 3. If a failure is taken place, the address of nonuse area of a register 5 is output to access the nonuse area of the memory 1 and this nonuse area is substantially used as the memory 1 of this channel.

Title: Differential amplifier
Inventor: AMANO KAORI
IPC: H03F3/45
Filed: 1991-03-28
Abstract: PURPOSE:To obtain a differential amplifier whose operating power supply voltage is set to a low potential or whose output voltage is set to a high level. CONSTITUTION:A differential input inputted from input terminals 51, 52 is amplified via a differential pair composed of NPN transistors(TRs) 3, 4. Its output is extracted from the collector of the NPN TR 4 and outputted from an output terminal 55 via an emitter follower composed of an NPN TR 6. A difference is produced between collector currents of the NPN TRs 3, 4 by the base current of the NPN TR 6 and a difference is produced in base-emitter voltage to produce an offset voltage with respect to the input. The offset is compensated by adding an NPN TR 5 to the differential amplifier.

Filed: 1986-03-25
Abstract: PURPOSE:To improve the response characteristic and the resolution of a correction function by adding an analog AFT function to a digital AFT function at the time of tuning, namely at the time of the stopping of an automatic channel selection. CONSTITUTION:At the time of the tuning, namely at the time of the stopping of the automatic channel selection, an AFT superimposing circuit 4 operates according to a control signal H from an automatic channel selection control circuit 1, an AFT signal G is superimposed on a tuning voltage E. Accordingly, to a detuning after the tuning, the correction of analog AFT operates. At the same time, the level of the digital AFT signal is detected by a window comparator 11, thereby, the correction by the digital AFT operates. The analog AFT is faster in the response than the digital AFT, so that the analog AFT preferentially operates to lead to an optimum tuning point. The resolution of the analog AFT is better than the digital AFT, so that the tuning is performed at the position nearer to the optimum tuning point. Accordingly, on the leading to the tuning point, the response characteristic and the resolution are improved.
