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.

Automatic programming apparatus includes: a material shape data input unit that receives input of data of material shape; a processing program storage unit that stores therein data of material shape and processed unit data; a processed unit data input part that receives an input of other-processed-unit-reference-type processed unit data referencing processed region shape data contained in the processed unit data; a processed region shape generating unit that generates processed region shape data in the processed unit data for partial processing, based on data of material shape and processed region shape data referenced by other-processed-unit-reference-type processed unit data; and a control command generating unit that generates control command data, based on processed unit data for partial processing containing processed region shape data.
摘要:
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 mobile station that performs wireless communication through a base station, includes a first connection setup request unit configured to make a first connection setup request for an emergency call and a normal call when communication performed in the communication region of the base station is in a congestion state, the emergency call and the normal call using a signal sequence that corresponds to a sequence number of a connection setup request signal used when communication performed in a communication region of the base station is in a normal state, and a second connection setup request unit configured to make a second connection setup request for another one of the emergency call and the normal call different from the first connection setup request, using a generated-signal sequence generated from the sequence number, when communication performed in the communication region of the base station is in the congestion state.

An image forming apparatus includes an operating portion that moves between a first operating position in which each of positioning members is moved to each of positioning positions and a second operating position in which each of the positioning members is moved to each of releasing positions through each of transmitting members and each of transmitted members when a first transmitting member and a first transmitted member are coupled to each other, and that carries out the movement to a first operating position to move a second positioning member to a second positioning position through a second transmitting member and a second transmitted member and carries out the movement to a second operating position to move the second positioning member to a second releasing position when the first transmitting member and the first transmitted member are decoupled from each other.

摘要:
An inexpensive fluorescent object is provided which may be used, for example, as a test object for color adjustment of a fluorescent endoscope system. The fluorescent object generates fluorescence while minimizing the generation of ‘noise’ at undesired wavelengths, and is made using a plastic that substantially does not deteriorate upon exposure to U.V. and visible radiation. A method of producing the fluorescent object is disclosed, namely, a plastic powder (such as PTFE) and an inorganic fluorescent powder (such as Mn-doped ZnS) are blended so as to form a mixture of these components, and the mixture is then molded by applying pressure to the mixture. An important feature of the invention is that heat is not added during any phase in the production of the fluorescent object, thereby preventing the inorganic fluorescent powder from being denatured when producing the fluorescent object.
