摘要:
A numerical control device (1) of a machine tool capable of controlling its spindle rotating speed includes: a program analyzing unit (2) that reads ahead a machining program (6) by one block or more and analyzes a command for the machine tool; and a command determining unit (3) that determines, based on a result analyzed by the program analyzing unit (2), whether a command posterior to a spindle control command causes any machining problem when the command is executed during a spindle rotating speed change, outputs a first command, in which some problem occurs in the machining, after the spindle rotating speed reaches the commanded rotating speed, and output a second command, which is other than the first command, before the spindle rotating speed reaches the commanded rotating speed.

A machine motion trajectory measuring device for measuring the motion trajectory of a machine used in an apparatus which controls the position of the machine by feeding back a detected position obtained by converting the rotation angles of motors for a plurality of movable axes and then driving the motors such that the detected position follows a commanded position is provided. The machine motion trajectory measuring device includes accelerometers for measuring the acceleration of the machine; and a motion trajectory measuring unit that measures the motion trajectory of the machine by obtaining the position of the machine by integrating the acceleration twice and correcting the position of the machine such that the profile of the position of the machine coincides with the profile of the detected position or the profile of an estimated position estimated using a model for simulating the response of the position of the machine to the commanded position.
摘要:
Corrected power for compensating for a reduction in the temperature of an endless belt that accompanies the entry of a recording material into a fixing nip portion is adjusted by correcting the power supplied to a fixing unit when the recording material enters the fixing unit with a correction power based on the difference between the update time of a power updating period and the time of the entry of the recording material.

An image-forming apparatus includes: a plural image-holding members, each image-holding member holding an image and being rotatable around a rotation shaft; a frame member that at least partially defines a space for accommodating the plural image-holding members therein; a cover provided to the frame member to open and close the space with respect to an outside, an inner side of the cover being formed with rotation shaft insertion holes each for receiving an end portion of the rotation shaft of a corresponding one of the image-holding members accommodated in the space; a supporting shaft that supports the cover such that the cover is pivotable with respect to the frame member, the supporting shaft being inserted into a supporting shaft insertion hole provided to the frame member or to the cover, the supporting shaft insertion hole being elongated in a direction having a vertical component when the cover closes the space; and a positioning mechanism that positions the cover with respect to the frame member when the cover closes the space, the positioning mechanism including at least two projections that project from one of the frame member and the cover, and that are spaced apart from each other in a direction of an axis of the supporting shaft, and projection insertion holes provided to the other one of the frame member and the cover to receive corresponding projections when the cover closes the space.
摘要:
A link establishing method to be implemented in a radio communication system sends a notifying signal notifying a plurality of radio resources from a base station when the base station judges that a collision of requests from a plurality of mobile stations has occurred, depending on a call request signal or a first connection request signal, and sends a second connection request signal from the mobile station using one radio resource selected from the plurality of radio resources notified by the notifying signal.

A drive transmission structure includes a driven shaft, a drive shaft, and a bearing member. The driven shaft has a drive receiving gear attached thereto and a first shaft portion near the drive receiving gear, to which a rotational force is transmitted. The drive shaft has a drive transmitting gear attached thereto and a second shaft portion near the drive transmitting gear. The drive transmitting gear is engaged with the drive receiving gear so as to transmit the rotational force. The bearing member has a first bearing and a second bearing, which respectively support the first shaft portion and the second shaft portion. In the drive transmission structure, the axis of the drive shaft does not intersect and is non-parallel to the axis of the driven shaft, and the first and second bearings are integrally formed with the bearing member.

A powder collecting container includes: a first chamber that is configured to store collected powder; a conveying unit that has a rotary shaft, and a powder conveying blade formed to be wound around the rotary shaft, the conveying unit being arranged along an upper-limit zone for accommodating powder in the first chamber and configured to convey powder which is contained in the first chamber and located at a position exceeding the upper-limit zone. A hollow member has an opening portion formed in a peripheral wall so that a powder conveying end of the conveying unit is located in the opening portion, and that the conveying unit passes through the hollow member. A second chamber has an inlet provided to face the opening portion so that powder conveyed by the conveying unit enters the second chamber from the inlet.
