Abstract: PURPOSE:To reduce the size of a device and to increase toner capacity by providing incidence/projection positions of all reflecting mirrors in an area determined by tangents to a photosensitive drum which are parallel to projection light from a reflecting mirror positioned at the most downstream side of the optical path of a laser beam. CONSTITUTION:The scanning beam 10 passed through an ftheta lens 1 and other image forming lens systems is refracted by reflecting mirrors 12a and 12b, and 13a and 13b to strike the photosensitive drum 5 of a laser printer. In this laser printer, the incidence/projection positions of the mirrors 12a and 12b are set in the area determined by a couple of tangents L1 and L2 to the photosensitive drum 5 which are parallel to projection light from the mirrors 13a and 13b positioned at the most downstream side of the optical path of the beam 10. Consequently, a developing unit 11 can be formed in a device margin space adjoining to the peripheral surface of the drum to increase the toner storage capacity while reducing the size of the device.

IPC: F04B39/00
Filed: 1993-05-20
Abstract: PURPOSE:To reduce the extent of pressure pulsation by branching off a refrigerant conducted to a discharge muffler from an interconnecting pipe, to a refrigerant passage to be formed by an inner groove and a muffler ring formed in an inner wall of this discharge muffler, and then rejoining these branched refrigerants together and discharging it to the discharge muffler. CONSTITUTION:A refrigerant drawn in is compressed by a piston 25 reciprocating in the inner part of a cylinder 24. At this time, since compression and suction are repeated in this cylinder 24, this discharge refrigerant has the pressure pulsation conformed to rotational frequency of a motor element driving a compressive element. The refrigerant with this pressure pulsation is conducted to a refrigerant from a discharge chamber 31 by way of an interconnecting pipe 32. Incidentally, this refrigerant coming out of a discharge port 38 of the pipe 32 is branched off at the refrigerant passage 37 consisting of the inner groove 35 or the like formed in an inner wall 34 of a discharge muffler 33. In brief, the refrigerant's pressure pulsation is decreased by flow passage resistance out of the refrigerant passage 37, while same pulsations are joined together at a discharge port 39 of a muffler ring 34, thereby countervailing each other, and then the eased pulsation is released to an interspace of the discharge muffler 33.

Abstract: PURPOSE:To purify highly frothing waste water with active sludge under a stable condition, by separating the froth formed on the surface of a mixed liquid in an active sludge aerating vessel from the aerating vessel, liquefying the separated froth, and then subjecting the liquefied froth to after-treatment such as solid-liquid separation. CONSTITUTION:Froth 5 formed on the surface of an active sludge-mixed liquid 4 in an aerating vessel 3 is sucked by a sand piper pump 11 and reserved in a liquefying reservoir 8, where the liquefied froth is flocculated by conjunct addition of an inorganic flocculant 9, e.g. FeCl3 or Ca(OH)2, and an organic macromolecular flocculant 10 or by addition of the organic macromolecular flocculant 10 only. The flocculated froth is separated into a solid part and liquid part by a dehydrator 12. The resultant dewatered cake 13 is disposed in the outside of the system. The dewatering filtrate 14 may be directly returned to the aerating vessel 3, but it is more effective to return the sludge to the aerating vessel 3 after the sludge is further flocculated or treated with active carbon, etc. The dewatered filtrate 14 may be handled as purified water 7 as it is.
