Filed: 1991-05-27
Abstract: PURPOSE:To correct slip from ideal density characteristics by a method wherein temperature ascent of a control IC due to the increase of a printing rate is fed back to a circuit element with a temperature coefficient to control the output. CONSTITUTION:A pair of transistors T4, T5 and a pair of transistors T6, T7 constitute a current mirror circuit, and a transistor T2 and a transistor T3 also constitute a current mirror circuit, and therefore, an electric current i1 and an electric current i2 are equal. In addition, the transistor T2 and 64 pieces of transistors T12 also constitute a current mirror circuit. As the result, all the electric currents i1, i2 and i3 become equal. The electric current i2 is determined by the electric current i1, and the electric current i1 is determined by a variable resistance R1. As the result, the electric current value 12 can be determined by an externally attached variable resistance R2. By this method, approximation of ideal density characteristics can be obtained without requiring a counter or digital filter for the calculation of a printing rate, or without making the width of a print image pulse variable.

Filed: 1977-12-19
Abstract: PURPOSE:To ensure the generation of the false random pulse featuring the extended circulating cycle by providing the counter and the ratch circuit memorizing the past contents of the parallel output with no increment of the bit number for the shift register and thus facilitating the D-A conversion. CONSTITUTION:The false random pulse generator circuit uses the exclusive logical sum of parallel output A-D of shift register 9 as the series input of register 9. In such pulse generator, ratch device 13 is provided to memorize output A-D which are before the fixed clock number of register 9, along with counter 10 to count the clock pulse of input terminal 1. The output of counter 10 is applied to series- parallel switching signal input terminal -PE of register 9 via NAND gate 12 to control register 9, and then the switching is carried out between the output of device 13 and gate circuit 4b delivering the exclusive logical sum. Thus, the circulating cycle is extended without increasing the bit number of register 9. As a result, the false random pulse featuring the txtended circulating cycle can be obtained.

Abstract: PURPOSE:To permit the continuation of combustion while controlling the generation of impurities as much as possible, by a method wherein the title controller is equipped with a safety control unit, changing the rate of combustion to the same, in which the amount of generation of impurities such as carbon monoxide or the like per unit time is small, when burning condition is judged as poor.

When the combustion rate is QA, the value IF of the flame current shows a stationary value IA'. However, when the concentration of oxygen is reduced and the value IF is reduced to the value IA, smaller than the level IL1, due to the shortage of ventilation or the like, the micro-computer reduces the combustion rate from QA to QB and operates a buzzer 9 and a lamp 10 intermittently regardless to the value of a load.
