摘要:
A method for producing a propylene-based polymer, including polymerizing propylene or propylene and an α-olefin except propylene in the presence of a catalyst with a horizontal polymerization reactor equipped with stirring vanes rotating around a horizontal axis therein by a continuous vapor-phase polymerization, which removes heat of polymerization by heat of vaporization of a liquefied propylene, wherein the reactor can set a plurality of area sections different in temperature in a horizontal direction inside the reactor, and satisfies at least one of i) a temperature difference, ΔT1=Tω−Tα, between an area section including an upstream end of the reactor (Tα) and a downstream end (Tω) thereof is 0.1 to 20° C. and ii) a temperature difference, ΔT2=Tx−Tz, between an area section including a catalyst feed part (Tx) and dew point (Tz) of a mix gas in the reactor is 0 to 5° C.

A sealing member seals an opening provided at one axial end of a rotatable container body of a toner supply container detachably mountable to an assembly of an image forming apparatus having a hollow cylindrical driving member. The sealing member includes a sealing portion provided at a side adjacent the container body to seal the opening, and a coupling portion provided at a side remote from the container body to receive a rotational drive force. The coupling portion includes a supporting portion provided on the sealing portion, an engaging portion provided at a free end of the supporting portion, and a displacing force receiving portion provided closer to the container body than the engaging portion. The engaging portion includes a rotational force receiving portion being abuttable in a circumferential direction of the driving member, and a locking portion being abuttable in an axial direction of the driving member.

A display device changes the gradation of pixels by a write operation of applying a voltage to the pixels a plurality of times. When newly changing the display state of pixels, the display device judges as to whether or not the pixels whose display state are to be changed are in a write operation. The display device starts the writing operation for those of the pixels that are not in a writing operation, and starts a new writing operation for those of the pixels that are in a writing operation, after the ongoing writing operation is completed. If a writing operation for pixels in progress of being updated and pixels with which a writing operation is to be newly started would lead to substantially large power consumption, the start of the writing operation for the pixels with which a writing operation is to be newly started is postponed.

An exhaust gas treating catalyst further improved in denitrification performance is provided. It is an exhaust gas treating catalyst containing a complex oxide represented by the general formula ABO3, where the A-site is composed of a lanthanoid (La) and barium (Ba), and the B-site is composed of iron (Fe), niobium (Nb) and palladium (Pd).

Conventionally, the developer in the developer supply container is discharged by an air-supply pump and a suction pump which are provided in the main assembly side of the image forming apparatus, and therefore, the developer is compacted by the increase of the internal pressure of the developer supply container resulting from the air-supply. Therefore, the proper suction of the developer from the developer supply container becomes difficult with the result of shortage of the developer amount to be supplied.A bellow-like pump is provided on the side of the developer supply container, and the pump alternately repeats the suction operation and the discharging operation through the discharge opening by a driving force inputted from the image forming apparatus side. By this, the developer can be sufficiently loosened, thus properly discharging the developer.

A door lock device includes an electrical drive source, which pivots a drive member from a predetermined neutral position, and a return urging member, which returns the drive member to the predetermined neutral position. The drive member pushes a locking lever with a first engagement portion and moves the locking lever to a lock position when the drive member moves from the predetermined neutral portion in a first direction in a state in which the locking lever is arranged at an unlock position. The drive member allows the double lock lever to move to the second position and disengages the first engagement portion from the locking lever when subsequently returned to the predetermined neutral position. The drive member pushes the double lock lever with a second engagement portion when moved again from the predetermined neutral position in the first direction.

A toner container detachably mountable to an image forming apparatus, includes a container body for containing toner and a coupling member. The coupling member includes a coupling portion provided at a side remote from the container body. The coupling portion includes a supporting portion which is elastically displaceable in an inward direction toward the axis of the container body and is elastically restorable in an outward direction away from such axis, an engaging portion configured and positioned to displace in an inward direction with the supporting portion and to engage with a slot of a hollow cylindrical driving member of the image forming apparatus when the supporting portion elastically restores in an outward direction, and a displacing force receiving portion configured and positioned to receive a force from a hollow cylinder of the image forming apparatus and cause the supporting portion to elastically displace in an inward direction.
