Title: Data signal modulating circuit
Inventor: NAKADA YUKIO
IPC: H04L27/00
Filed: 1983-08-19
Abstract: PURPOSE:To transmit surely a carrier only when a data exists by deciding the presence of data from a transmission data signal so as to extract an on/off control signal of the carrier even when the carrier on/off control signal is not inputted. CONSTITUTION:When a transmission data signal 3-7 is inputted to an input terminal 3-5 of a modulator and the mode is changed from the idle state to the active state, a data sense circuit 3-3 comprising a retrigger type monostable multivibrator or a counter or the like detects the head of a frame to turn on a data sense signal 3-9. A carrier signal output gate 3-4 is controlled by the data sense signal 3-9 and outputs a transmission carrier signal 3-10 only when the data sense signal 3-9 is turned on. Further, the data sense circuit 3-3 detects the end of frame at a prescribed time T4 after the transmission data signal 3-7 changes from the active state to the idle state so as to turn off the data sense signal 3-9.

Abstract: PURPOSE:To prevent the misdetection of the temperature of a fixing roll due to the noises, etc., by reading the temperature of the fixing roll by several times and deciding the temperature of the fixing roll based on the average level of those read temperatures. CONSTITUTION:When a scanner motor 6 reaches a prescribed rotational frequency, a scanner motor control part 5 returns a scanner ready signal 15 to a CPU 1. The CPU 1 sends a heater ON signal 16 to a fixing part 7 and turns on a heater contained in a fixing roll 106 to heat the roll 106 up to a printing temperature. Then the temperature of the roll 106 is read by several times by a thermistor 15 set on the roll 106. These detected temperatures are stored in a RAM and also an averagelevel is taken among these stored temperatures. Thus the temperature of the roll 106 is decided. A fixing part 7 sets the surface temperature of the roll 106 to a heater temperature signal and returns them to the CPU 1. The CPU 1 applies the ON/OFF control to the signal 16 in order to keep the received temperature at the printing temperature.

A selector 16, designates the combination and selects an output result that is outputted from a memory 12 and a result that is outputted from the memory 13. A control circuit 18 discriminates whether or not the codeword corresponding to the combination is a partial combination. When it is not, the selector 16 successively selects a codeword, that is already outputted from the memory 12 and a codeword outputted by the memory 13 and, constructs a variable length codeword. Thus, it is possible to reduce a time that is needed for code word allocation.
