Novel oxindole derivative and salt thereof represented by the general formula, ##STR1## wherein R.sup.1 is a hydrogen atom, a lower alkyl group, a lower alkenyl group, a lower alkynyl group or a phenyl-lower alkyl group; R.sup.2 is a hydrogen atom or a lower alkyl group; R.sup.3 is a hydrogen atom, a cycloalkylcarbonyl group, a benzoyl group which may have 1 to 3 substituents selected from the group consisting of a halogen atom, a lower alkyl group and a lower alkoxy group on the phenyl ring, or a phenyl-lower alkanoyl group which may have halogen atoms as the substituents on the phenyl ring; provided that when R.sup.4 is a hydrogen atom, then R.sup.3 should be neither a hydrogen atom nor a lower alkyl group.The novel oxindole derivative and salt thereof possesses anti-peptic ulcer effects and are useful as anti-peptic ulcer agents.
摘要:
A cap is configured to be attached to a developer container that discharges developer contained in the container body out of the container body through a discharge port defined in a portion of the container body. The cap includes a first attaching member and a second attaching member that are detachably assembled into one piece. When the first attaching member or the second attaching member receives a rotary force, the first attaching member and the second attaching member are separated from each other, and only the first attaching member is released from the container body.

A correction control method includes performing correction control to bring a control value to a target value or a change through a prediction control system that previously applies a predetermined amount of correction and a predetermined timing. The prediction control system is constructed without performing data offset processing for deriving the predetermined amount of correction and the predetermined timing.

Provided is a powder container having a new structure capable of stable discharge and transport of a powder contained in a container by enabling the powder to be reliably discharged to the outside of the package while preventing the powder from spilling and flying out of the container. The powder container has a container body (138) for transporting powder contained therein from a first end side (138a) to a second end side (138b) thereof by self-rotating; a nozzle receiver (139) having a nozzle receiving hole (insertion section) (139a) arranged inside the second end side of the container body and configured to allow a transport nozzle (162) having a powder receiving inlet (170) to be inserted therein, and a supply port 139b arranged in at least a part of the nozzle receiver (139) and configured to supply the powder in the container body (138) to the powder receiving inlet (170): and a shutter (140) supported by the nozzle receiver 139 and configured to open and close the nozzle receiving hole (insertion section) 139a by sliding in response to insertion of the transport nozzle 162 into the nozzle receiver (139).

An image forming apparatus in which a medium container is installed includes a main body, an image forming unit, a medium container a container body at least partially formed of a deformable material, a drawer to hold the medium container thereon and movable between a first position and a second position, a medium transport unit including a medium outlet port provided on a distal end of the medium container, and a medium receiving unit disposed at the second position of the drawer and connected to the medium transport unit provided on the medium container, and a medium transport facilitator mounted on the drawer to contact the medium container set in the drawer from below to move the medium contained in the medium container toward the medium transport unit at the second position.
摘要:
A fluctuation detecting unit detects a fluctuation of an endless belt generated when a sheet is brought into contact with a predetermined position of the endless belt at an upstream side in a conveying direction from a nip portion based on fluctuation information acquired by a fluctuation information acquiring unit. An entry timing estimating unit estimates entry timing of the sheet into the nip portion based on a detection of the fluctuation. A correction control unit corrects a speed fluctuation of the endless belt generated when the sheet enters the nip portion by performing a feedforward control of a first driving unit based on the entry timing.
摘要:
There is provided a technique for introducing grafted side chains having a narrow molecular weight distribution onto a molded organic polymer substrate, for example polyolefin substrate, while maintaining the form of the substrate. One aspect of the present invention relates to a method of manufacturing a grafted material, comprising the steps of (a) irradiating an organic polymer substrate with ionizing radiation, and then bringing a polymerizable monomer and a polymerization initiating group-introducing agent into contact with the substrate, thus introducing grafted side chains having polymerization initiating groups on ends thereof onto trunk polymer of the substrate, and (b) then bringing a polymerizable monomer into contact with the substrate, thus causing the grafted side chains to grow.
摘要:
A drive control device for a brushless motor having a rotor and a plurality of coils with different phases can be included in an image reading apparatus or an image forming apparatus. The drive control device may include a detection target configured to rotate in synchronization with rotation of the rotor and having formed thereon a pattern representing modulation information, a detector configured to read the pattern and to output modulated output signals, a demodulator configured to demodulate the modulated output signals and to obtain demodulated information, and a controller configured to control rotation of the rotor on the basis of at least the demodulated information obtained by the demodulator.
