Patent JP-H05167819-A (JP)
Title: Facsimile equipment
Inventor: MUKAI KOICHI
IPC: H04L29/08
Filed: 1991-12-13
Abstract: PURPOSE:To efficiently select transmission speed by varying the transmission speed owing to the number of error frames at the time of fallback. CONSTITUTION:A register part 1 accumulates the number of error frames sent from a reception side. A speed selection part 2 selects the optimum value out of one or two stages of the transmission speed of an error frame to be re- transmitted from the present speed based on the number of error frames accumulated in the register part 1. In such a case, a threshold level of the number of error frames to be selected is decided by the characteristic of a telephone circuit and that of a modem, and assuming the value of the threshold level as (m) and the number of error frames as (n), modem speed is decreased by one stage when it is n<m. When it is n>=m, the speed is decreased by two stages. A control part 3 sets a transmission speed of the re-transmission frame to a modem part 4 at the next stage due to transmission speed information from the speed selection part 2. The modem part 4 performs re-transmission at speed instructed by the control part 3.

IPC: H04B10/278
Filed: 1989-12-22
Abstract: PURPOSE:To improve the reception sensitivity by converting the quantization state of an optical signal in an optical receiver from a coherent state into a squeezed state. CONSTITUTION:An optical transmitter applies frequency shift keying(FSK) modulation to a coherent light to form an optical signal. An optical receiver converts the quantizing state of an inputted FSK optical signal from the coherent state into the squeezed state at first, and uses an optical filter to extract only the signal component corresponding to the space from the FSK optical signal converted into the squeezed state, applies homodyne detection to the extracted signal component and identifies the detection signal depending whether the detection signal resides within two threshold levels or at the outside of the levels. Thus, a high reception sensitivity characteristic is obtained.

IPC: H01L27/04
Filed: 1989-12-20
Abstract: PURPOSE:To prevent the reduction of a power supply voltage in an IC due to the simultaneous change of plural output signals and the generation of malfunction by adjusting and controlling the change timing of an output signal from a required line out of plural lines. CONSTITUTION:When a selecting circuit 3 sets up both selection setting signals A, B to 'L', and AND circuit 31 outputs an 'L' signal to a switching circuit 2a and AND circuits 32, 34 output 'H' signals respectively to switching circuits 2b, 2c. Thereby an input signal I1 is delayed and outputted and input signals I2, I3 are outputted as it is. When the signals A, B are respectively set up to 'H' and 'L', the input signal L2 is delayed and outputted and the signals I1, I3 are outputted as it is. Thus, the delay of an optional input signal out of the signals I1 to I3 can be selected by setting up the signals A, B respectively to 'L' and 'H' or setting up both the signals A, B to 'H'. Consequently, the coincidence of changing timing of output signals from respective lines can be prevented and the reduction of the power supply voltage and the generation of malfunction can also be prevented.
