Filed: 1983-05-31
Abstract: PURPOSE:To remove the clogging with a simple method, and to use continuously the apparatus by providing a pressing device for exerting pressing force to a thin disk at the end part of a filtration member. CONSTITUTION:The waste water contg. activated sludge and solids such as iron powder flows in from an inflow port 2. The iron powder, etc. in the waste water is attracted to the surfaces of disks 5 and 5, since a magnetic flux passes through the clearance part between the disks 5 and 5 and spacers 6 and 6 due to the magnetization by a permanent magnet. And other solids in the waste water are left mostly on the circumferential surfaces of the disks 5 and 5. In addition, since the disks 5 and 5 are pressed by rollers 11 and 11, fine solids clogging the clearance between the disks 5 and 5 are squeezed out over the circumferential surfaces of the disks 5 and 5 along with the revolution of the disks 5 and 5, and removed. Said iron powder and solids are carried to the location of a scraper 8 and discharged into a solids discharging part 10. In this way, the apparatus can be used continuously.

Title: Cooling device
Inventor: ONO HIRONORI
IPC: G03G21/20
Filed: 1985-05-02
Abstract: PURPOSE:To cool whole operating member by a centralized cooling, by cooling locally the part being adjacent to a heat source of the operating member, and also inhaling and blowing an external air to the vicinity of the most adjacent point of the heat source and the operating member so as to diffuse and cool a divergent heat from the heat source. CONSTITUTION:A photosensitive body 2 which rotates itself and repeats each process of electrification, exposure, development, transfer and cleaning receives locally heat of a fixing lamp 3 from an inrush port through which a transfer material goes into a fixing device. In this case, the photosensitive body 2 rotates itself and executes each process, therefore, receives heat successively in each part, and as a result, a temperature rise occurs as a whole. A radiation heat 13 which has been generated from the fixing lamp 3 passes through a gap of a heat roller 5 and a heat insulating plate 11 and reaches extending over the whole width to the vicinity of the most adjacent point to the heat roller 5 of the photosensitive body 2, and in that case, an air flow 12b by an air blower 1b is blown to the part which is influenced by the radiation heat 13. In case of cooling concentrically some one part of the photosensitive body 2, the blowing takes a way more heat quantity than the exhaust, and the cooling effect also becomes high as much. In this way, a temperature rise of the whole operating member is suppressed.

Abstract: PURPOSE:To prolong the life of a filter and to decrease the amount of ozone included in the discharged air by providing an activated carbon filter and a catalytic filter on an air leading path which leads the air around a corona discharger to an absorbing means. CONSTITUTION:The air containing the ozone developed in a primary electrifier is led in a downstream direction in a main body duct 14, passes through a guiding duct 17, and is discharged out of the device by a discharging fan 15.

Especially, when the catalytic filter 18 and the activated carbon filter 19 are provided from the upstream of the air flow in that order, the ozone resolving efficiency can be improved by initially bringing the air whose ozone density is high into contact with the catalysis. Consequently, the life of the filters 18 and 19 can be prolonged, and the content of ozone included in the discharged air can be decreased.
