Patent JP-S61111030-A (JP)
Title: Photodetector
Inventor: SAKURA NARIYUKI
IPC: H04B10/50
Filed: 1984-11-05
Abstract: PURPOSE:To block passing of a DC component equivalently without using a capacitor by feeding back the DC component in an output of a parallel feedback amplifier to which a photodetector is connected to the parallel feedback amplifier via a buffer amplifier. CONSTITUTION:An output of the parallel feedback amplifier 2 is fed back via a DC buffer amplifier 20 and resistors R2, R3. The relation of V1 V0-R1 R2/(R1+R2).I is obtained with R1/A<<R2, where A is the open loop gain of the amplifier 2. The relation of v1=-R1i is established with respect to the AC component changing faster than the time constant comprising a resistor 22 and a capacitor 26. Thus, the conversion gain of the DC component is R1R2/R1+R2 and the conversion gain of the AC component is R1. The conversion gain of the DC component is made sufficiently smaller than the conversion gain of the AC component by selecting the resistors as R2<<R1 and the fluctuation of the DC component is neglected substantially.

Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To confirm and display the reception of electronic mail, without a modem control terminal by storing once executed communication operation and reproducing a stored communication protocol, when it is desired to confirm the reception of electronic mail. SOLUTION: Two operating modes of a communication protocol storage mode and a communication protocol reproducing mode are added to a conventional modem. The communication protocol storage mode is a mode for the modem to prepare single operation, and the communication protocols clearly distinguished into transmission data and reception data are stored in the order of execution. The communication protocol reproducing mode is a mode for reproducing the stored protocols and at such times, the modem plays the role of a terminal even without its own terminal. Then, when there is a received electronic mail at the time of log-in with a communication center, data reported from that communication center are received and displayed on the modem.
