Abstract: PURPOSE:To assure elimination of stuck toner by detecting humidity of periphery of the cleaning device stuck with toner, such as a photosensitive drum, an intermediate transfer body, or a transfer drum, etc., and variably controlling bias voltage impressed to a cleaning means according to the detected humidity. CONSTITUTION:A toner image formed on a photosensitive drum 81 is transferred to a transfer paper 87 by a transfer charge 82. Then, the part where the transfer was carried out is cleaned by a brush roll 91 impressed with bias voltage V1 and V2 controlled by a micro computer 300 based on the detected result of a humidity sensor 95 and a recovery roll 92 after having residue toner uniformly electrified by a toner charger 85. Here, the bias voltage V1 and V2 of the rolls 91 and 92 can be changed over to a multiple number of stages according to relative humidity. Therefore, since variance in the cleaning effect depends greatly on variation of humidity, stable cleaning is carried out with this means by variable control of the bias voltage according to the detected humidity of a humidity detection means.

Abstract: PURPOSE:To shorten time required for outputting signals equalized for a certain degree at first by constructing two systems for which transversal filters are cascade connected. CONSTITUTION:Input signals are A/D converted and then taken in through a memory 5 to a CPU 8. The CPU 8 performs synchronous addition, improves S/N, removes DC offsets and performs transfer from the CPU 8 to the memory 4. Thereafter, the read signals of the memory 4 are inputted to the transversal filters 2 and 3. The CPU 8 takes in the signals of the memory 4, obtains the difference with reference signals and adjusts the filters 2 and 3 by a prescribed arithmetic operation. Then, at the point of time when residual errors become smaller for the certain degree, the added result of the output of an A/D converter 1 and the filter 2 is outputted as output signals. Further, after waveform equalization is continued by using the filter 3, the filters 2 and 3 are cascade connected and the output of the filter 3 and the output of the converter 1 are newly added and outputted.

CONSTITUTION:When a slide valve 27 allows an outdoor side heat exchanger 10 and the suction side of a compressor 4 to communicate with each other in a state that a piston 12 is moved by a spring 13 in the direction of a high-pressure chamber R1, an indoor side heat exchanger 9 and the outlet side of the compressor 4 communicate with each other via the high-pressure chamber R1. In this instance, a pressure changing chamber R2 and the suction side of the compressor 4 are disconnected from each other by a pilot solenoid valve 15 and, when the pilot solenoid valve 15 is opened at the time of supplying power thereto and the pressure changing chamber R2 communicates with the suction side of the compressor, the slide valve 27 allows the indoor side heat exchanger 9 and the suction side of the compressor to communicate with each other in a state that the piston 12 is moved against the spring 13 by pressure differences. Thereby, the outdoor side heat exchanger and the outlet side of the compressor communicate with each other via the high pressure chamber. Accordingly, starting characteristics in a heating operation can be improved, and the change-over from a heating cycle to a cooling cycle can be done in a relatively short period of time.
