Title: Pulse width modulation circuit
Inventor: ONDA TOSHIKAZU
IPC: H03K7/08
Filed: 1985-06-18
Abstract: PURPOSE:To decrease ripple rate generated at demodulation, delay in propagation and to improve resolution by applying sequentially an output signal from the most significant bit to the least significant bit among output signals of a counter from the least significant bit input terminal to the most significant bit input terminal of a comparator. CONSTITUTION:A clock circuit 2 outputs a clock pulse of a prescribed frequency to a counter 1, which outputs the input number of the clock pulse from output terminals Q1-Q4. The output signal from the most significant bit Q4 to the least significant bit Q1 among output signals of the counter 1 is inputted sequentially from the least significant bit input terminal B1 to the most significant bit input terminal B4 of the comparator 3. The comparator 3 compares the digital signal B fed from the counter 1 with the digital signal A being a data to be modulated, and when A>B, an H level signal is outputted and in other case, an L level signal is outputted. Thus, the output signal of the comparator is in a form where H and L levels are scattered in one period and a pulse width modulation signal with very small cycle time is obtained.

Inventor: ANZAI MASAYASU
IPC: G03G15/20
Filed: 1977-11-07
Abstract: PURPOSE: To eliminate the need for using a plurality of lamps for controlling paper width and prolong the life of a heat roller by providing a heat exchanging means for evening surface temperature in contact with the heat roller.  
     CONSTITUTION: A backup roller 4 is a heat pipe which comprises sealing liquid  such as water, alcohol, etc. within a core roller 9 of good heat conductivity such as copper, aluminum, etc. and affixing a wick 10 absorbing the liquid on the inside surface. When the width of the recording paper 1 to be fixed is smaller than the width of a heat roller 3, the backup roller 4 is a heat pipe and the evaporation liquefaction action of the liquid which has absorbed and entrapped the heat of the high temperature part suppresses the temperature elevation of the portion not in contact with the paper and increases the temperature of the portion pressing the paper, heating the paper from the back side. As a result, the quantity of the heat absorbed in the paper by the heat roller 3 is decreased and the temperature decrease of this portion is suppressed. In this way, the temperature differences are kept low and the life of the elastic body of the heat roller surface may be prolonged.
