Title: Speed detecting device
Inventor: TERAJIMA MASAYUKI
IPC: G01P3/44
Filed: 1984-08-31
Abstract: PURPOSE:To output a stable speed detection signal by stopping the differentiating operation of a differentiating circuit temporarily with an inflection point detection signal. CONSTITUTION:Normally open contacts S1 and S4 of the differentiating circuit 2 are broken unless there is a signal from an inflection point detection part 3, and normally closed contacts S2 and S3 are held closed unless there is a signal from the detection part 3. The output signal of a saw-tooth wave generating circuit 1 is converted into a rectangular wave signal Q, which is passed through a shift register 3a to input output signals Q1 and Q2 to an exclusive OR gate 3b. When the signals Q1 and Q2 are 1 and 0, or 0 and 1, an output signal Q3 is obtained. Output signals Q1 and Q2 of the register 3a, however, are 0 and 0, or 1 and 1 almost at the inflection point of the saw-tooth wave of the rectangular wave signal Q. Thus, the inflection point of the saw-tooth wave is detected and the output signal Q3 of the gate 3 is passed through a pulse width adjusting circuit 3c to control the normally open and normally closed contacts S1-S4, and consequently the operation of the circuit 2 at the inflection point is stopped temporarily to obtain the speed detection signal from a resolver stably.

Title: Toner supply control method for image forming device
Inventor: SAWAI YUJI
IPC: G03G15/08
Filed: 1985-08-21
Abstract: PURPOSE:To obtain a copy having sufficient density from an original whose black part area ratio is large and to prevent an end display from being misread by setting a maximum toner supply rate higher than a manual settable level and making the toner end display when the degree of toner sticking is deficient. CONSTITUTION:When the output of a sensor 14 exceeds a reference control value K1 and is less than K2, it is judged that images with proper density are obtained with the current toner concentration, and toner is supplied at a supply rate corresponding to the 20% black part area rate of the original. When the output of the sensor 14 exceeds the value K2, it is judged that the concentration is lower than the toner density for proper density images, and it is checked whether or not the level corresponds to the 100% original black part area rate at which manual setting is impossible; when not, toner is supplied at a supply rate corresponding to the 100% area rate in a next process to obtain a copy with good reproducibility. On the other hand, when the image density does not reaches the proper level although the toner supply rate is maximum, it indicates that there is toner in neither a casing 8 nor a toner bottle 10, so the toner end display is made and processing regarding the supply of toner is performed.
