Filed: 1999-10-19
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device where a constant image density can be maintained by agitating aggregated toner in a vicinity of an opening for toner replenishing by having a blade part of a toner agitator come into contact with a top edge of the toner replenishing opening and preventing the deterioration of toner concentration due to aggregation of the toner. SOLUTION: When the toner agitating member is driven, a free end of the blade part 49a is brought into contact with a casing end part 41a restricting a top end of the toner replenishing opening 48. Since this blade part is provided with elasticity, it is bent back and forth by an impact of contact with the casing end part and the toner 50a in the vicinity of the toner replenishing opening is agitated. Thus, blocking of the toner in the vicinity of the toner replenishing opening is relieved and the aggregation of the toner caused by passage of time can be prevented. Therefore, control can be carried out to obtain a desired toner concentration without deterioration of the toner concentration due to the passage of time.

Abstract: PURPOSE:To obtain an absorptive effect of vibration even when an operative condition large changes, by detecting driving torque, generated between a magnetic particle-type electromagnetic coupling provided halfway a shaft transmitting driving power and a prime mover, by a torque detector and controlling an excitation current in the electromagnetic coupling. CONSTITUTION:A torsional strain, generated between a magnetic particletype electromagnetic coupling 1 and a driving shaft 2, is detected by a torque detector 3.

Abstract: PROBLEM TO BE SOLVED: To make it possible to monitor a film thickness without using a calibration curve by measuring the difference in the detection times between the detection signals of the respective absorbances detected by two absorbance measuring systems and determining the absorbance and the flying speed of a particle. SOLUTION: The apparatus has the first and second absorbance measuring systems. The respective measuring systems emit one piece each of searching luminous flux. The first searching luminous flux 19 and the second searching luminous flux 20 are so arranged as to cross the extension of a line connecting an evaporating source 2 and an upper opening part so as to prevent the superposition of these luminous fluxes. The flying particles from an evaporating source 2 first passes the first searching luminous flux 19 and attenuates the luminous flux thereof. The flying particle passes the second searching luminous flux 19 after a certain time and attenuates the luminous flux intensity thereof. The time difference described above is detected as the time lag between the first searching light intensity signal 39 and the second searching light intensity signal 40 by a data processing system 46.  The flying speed of the particle is determined from the time difference described above and the distance between the centers of the two luminous fluxes.
