Inventor: KOGYO TAKASHI
IPC: H04L27/26
Filed: 1995-06-05
Abstract: PURPOSE: To easily select any transmission mode with a simple circuit configuration while providing several transmission mode functions. CONSTITUTION: A calling signal is received and when this signal is 1100Hz, its band is passed through a filter 14a. When it is detected by a comparator 14c, a detected signal is applied to a circuit 20. This detected signal is applied to a circuit 2. When a 697Hz signal and a 1209Hz signal are received from a counter device as PB signals simultaneously with the reception of this detected signal, the 697Hz signal passes its band through a filter 11a and detected by a comparator 11c and applied to a decoder 19. The 1209Hz signal passes its band through a filter 15a and is detected by a comparator 15a and applied to the decoder 19. It is recognized from these detected signals by the decoder 19 that the code of the PB signal is (1) and a figure code and a PB detect signal are applied to the circuit 2.  The circuit 2 selects the facsimile transmission mode function while considering the signal at 1100Hz as well.

Title: Optical receiver
Inventor: IMAMURA KEIICHI
IPC: H04B10/2507
Filed: 1989-05-31
Abstract: PURPOSE:To attain waveform shaping while excluding the effect of noise effectively even when an input signal level is decreased by referencing a reference voltage corresponding to an input signal level so as to shape the waveform. CONSTITUTION:An optical signal inputted to a photodetector PD is amplified by a preamplifier IC1 connecting to a feedback resistor Rr, and reaches an IC2 being an output buffer through a circuit 2 whose transfer function is H(S). On the other hand, when an optical current flows to the photodetector PD, a voltage is generated across a resistor R1, the voltage connects to an inverting input of an amplifier IC3 and the amplifier IC3 supplies an output corresponding to the generated voltage to a noninverting input of the IC2. Thus, the level is changed in response to the light receiving power so as to be in the middle of the amplitude of the signal voltage given to the inverting input of the IC2. Thus, the effect of noise caused around 'H' level and 'L' level is hardly caused and the reception sensitivity is substantially improved.
