Title: Magnetic brush cleaning device
Inventor: OKUNO TATSUO
IPC: G03G21/00
Filed: 1980-11-07
Abstract: PURPOSE:To obtain a magnetic brush cleaning device of high reliability by using plural sets of magnetic brushes of different roll biases. CONSTITUTION:Two or other pieces of magnetic brush rolls 1, 2 in contact with a photoreceptor 3 are set with low bias voltages of V1<V2 at different voltages V1, V2. The brush 1 is used for a toner of low electrostatic charge quantity and the brush 2 for a toner of high electrostatic charge quantity. Therefore, the range of cleanable electrostatic charge quantity is expanded and the toner of high electrostatic charge quantity can be cleaned as well. Hence, no influence are given upon the cleaning characteristics of the toner of normal electrostatic charge in spite of increasing of a precleaning Corotron current value in order to decrease the distribution quantity of the reversed polarity toner. As a result, the magnetic brush cleaning devie of high reliability is obtained.

Filed: 1992-05-22
Abstract: PURPOSE:To prevent damage to an air-feeding pipe when a mixture of various kinds of refuse is burned together by providing in the lower part in a primary combustion furnace a water-cooled jacket in which a plurality of air-feeding pipes having air ejection holes are arranged at specified intervals. CONSTITUTION:The air-feeding part of a primary combustion furnace 11 comprises an air conduit 21 and a plurality of air-feeding pipes 22 arranged in parallel; the air-feeding pipes 22 have air ejection holes 23 at specified intervals in each. Since waste refuse containing metal parts, such as a waste tire, is burnt in the primary combustion furnace 11, it would occur that molten metal sticks to a water vessel casing 24. But by virtue of water contained in the water vessel casing 24 molten metal almost instantly solidifies at the part of the contact irrespective of the furnace temperature and stands. Therefore the air-feeding pipes 22 are free from deformation, which would be caused by a sudden change in the furnace temperature or metal component, and enabled to feed air into the furnace without changes from the initial condition. And the function of the air-feeding piper 22 keeps stabilized and their maintenance is made easier.

Filed: 1982-09-10
Abstract: PURPOSE:To enable the detection of leak from each heater with provision of just a piece of current control element for each one piece of preheaters by detecting the leak from the difference in the magnitude and phase between the leak current when all current control elements are turned off and the leak current when the current control elements are successively turned on by a controller.

A phase meter 7 which measures the phase of the leak current is provided in addition to a zero phase current transformer 4, an ammeter 5 which measures the leak current, and a controller 6 which controls automatically a bidirectional thyristor 2. The leak current can be detected from the change in the magnitude of the leak current when the bidirectional thyristor is turned on and off in the case of the preheaters connected between U phase-V phase and between V phase-W phase. The leak current can be detected from the change in the phase of the leak current when the bidirectional thyristor is turned on and off in the case of the preheaters connected between the W phase-the U phase and therefore the presence or absence of the leak of all preheaters is judged by performing the on-off control of the bidirectional thyristor successively with respect to all juxtaposed preheaters.

Inventor: MASUDA MITSURU
IPC: H03J7/02
Filed: 1990-06-15
Abstract: PURPOSE:To shorten pull-in time by sharply reducing a common frequency fluctuating component in a signal propagation path by inputting an AFC signal from a demodulator in a synchronized state to the other demodulator in an asynchronous state, and moving the operational voltage. CONSTITUTION:An N kinds of modulated signals 21A-23A passed through the same signal propagation path are inputted to the demodulator and demodulated by a reproduced carrier signal. However, assuming that a demodulator 21 is set in the synchronous state and other demodulators 22 and 23N are set in the asynchronous state, the central voltage of an AFC signal 21B from the demodulator 21A in the synchronous state is transmitted to a controller 5 and stored. Further, the controller 5 transmits the central voltage of this AFC signal 21B to an AFC circuit 3B or the like of the other demodulator as AFC signals 22B and 23B and moves the operating point so as to obtain the same voltage as this central voltage. Thus, since moving to a state close to AFC pull-in by such a control operation, AFC sweeping width can be turned to the synchronous state with narrow sweeping width.
