Title: Combustion device
Inventor: NAGANO OSAMU
IPC: F23L1/00
Filed: 1985-03-11
Abstract: PURPOSE:To eliminate a disturbance of regular flow and improve a performance of combustion even if a certain distance is found between a thermal shielding plate and burner flame outlets by a method wherein a flow regulator plate for regulating supplied air required for combustion is arranged below the burner flame outlets. CONSTITUTION:A flow regulating plate 6 is arranged between respective burners below flame outlets 1a of the burner 1, and several flow regulating outlets 6a are made at a position where it is located between the respective burners 1. In this way, the supplied air required for combustion in the burner 1 is taken through the flow regulating holes 2 in the thermal shielding plate 2 and again regulated by the flow regulating holes 6a arranged at the flow regulating plate 6 near the burner flame holes 1a. Since the thermal shielding plate 2 and a heat exchanger 3 are of a highly sealed unit, immersion of supplied air from the heat exchanger is prevented. Further, it is possible to prevent the heat from being escaped to the lower part of the burner 1 and so they may also act as a thermal shielding plate.

Abstract: PROBLEM TO BE SOLVED: To surely reduce the quantity of developer remaining and adhering in a layer state to the inner peripheral surface of a cylindrical developer container to be as small as possible by temporarily rotating a feeding member in a direction opposite to a rotating direction where the developer should be fed. SOLUTION: In this developer supply device 1; when toner 10 in a toner cartridge 20 is hardly left, a control signal from a control part 11 is fed to a motor driving device 4 so as to drive a driving motor in a reverse direction for a specified time. Thus, a 1st driving shaft 40 is rotated in the reverse direction and the spiral agitator 6 of the cartridge 20 is also rotated in the reverse direction. In such a case, the agitator 6 is rotated in the reverse direction while receiving the carrying load of the toner 10, so that a spiral part is deformed toward the inner peripheral surface 21a and the outside diameter of the spiral part is in an enlarged state. As a result, the toner adhering in the layer state to the inner peripheral surface 21a of a cartridge main body 21 is scraped by making the agitator 6 whose outside diameter is enlarged directly touch the toner.
