摘要:
Time required for location registration is reduced and concentration of location update signals caused when a group moves is prevented. Each mobile node and a mobile router sends a location update request to a local location manager near to the area in which it exists, so that time required for location registration can be reduced, and it is possible to prevent pressure on wireless resources and temporary increase in communication traffic within a mobile network, which may be caused by concentration of location update signals when a group moves as in the case of a train with a lot of passengers having mobile nodes. Thereby, even if location registration is not correctly performed by a mobile router, which sends a location update request on behalf of mobile nodes existing in the space of a moving body, due to the communication condition or a failure, it can be dealt with.

A data communications system which communicates data via a data communications network, includes: an information extraction unit configured to extract an extraction target from received data; an comparison information generator/transmitter unit configured to generate and transmit comparison information including the extraction target extracted by the information extraction unit; a comparison unit configured to compare the received comparison information with the received data; and a cancellation processor unit configured to delete the received data, when the received comparison information agrees with the received data.

A sheet conveying apparatus includes a sheet feed tray on which sheets of a plurality of sizes which differ in length in a sheet widthwise direction perpendicular to a sheet conveying direction, a conveying unit which conveys a sheet on the sheet feed tray to a predetermined processing position, a sheet position detector which has a plurality of light-emitting units respectively arranged at positions corresponding to different sheet widths and one light-receiving unit capable of moving to positions corresponding to the plurality of light-emitting units, a light reception position detector which detects the position of the light-receiving unit, and a control unit which selects one of the plurality of light-emitting units on the basis of a detection result from the light reception position detector. The sheet position detector causes the selected light-emitting unit to emit light and detects the convey position of an end portion of a sheet in the widthwise direction which is conveyed by the conveying unit on the basis of an output signal from the light-receiving unit when the light-emitting unit is caused to emit light.

A sheet supplying device includes a stacker for placing sheets; a delivery device for separating and feeding the sheets on the stacker; a register device for temporarily holding a sheet; a sheet conveying guide for guiding the sheet from the register device to a processing position; a sheet sensor disposed between the delivery device and the register device for detecting the sheet; at least one driving device for driving the delivery device and the register device; a conveyance control device for controlling the driving device so that the delivery device and the register device form a loop of the sheet according to a signal from the sheet sensor and an overlap sensor disposed between the register device and the processing position for detecting overlapping of the sheet. An overlap determining device determines overlapping of the sheet according to signals from the sheet sensor and the overlap sensor.

Backgate-characteristics determination method and device that make for curtailing the fabrication of semiconductor circuit elements having defective backgate-characteristics. Initially a first C-V curve 30 representing the relation between a voltage applied to the obverse face of a wafer 20 serving as a substrate for semiconductor circuit elements, and its capacitance, is found. Next, a second C-V curve 32 is found through applying a voltage to the reverse face of the wafer 20. The backgate characteristics for the semiconductor circuit elements are determined based on a voltage-shift amount 34 for the wafer 20, found from the first C-V curve 30 and the second C-V curve 32.
摘要:
Documents to be imaged which lie one upon another in a prescribed order of page on an automatic document feeding device are automatically fed one by one to a scanning reference position defined in an image scanning position of an image processing device and discharged, after being imaged, to a discharge tray in the same order of page as those initially stacked. The document sent out from the image scanning position to a delivery passage after being imaged is sent back to the document scanning position through a return passage to be turned over. When the document being sent back is introduced into the image scanning position by the longitudinal size of the document, document transporting means is reversed to discharge the document, thereby to shorten the time required to discharge the document from the image scanning position to the discharge tray through a document discharge passage. The documents after being imaged can be discharged in the desired order of page on the discharge tray by turning over the documents before being discharged.
摘要:
In a device and method for feeding one by one documents including a preceding document to be fed earlier and a following document to be fed later to an image scanning station having a scanning reference point, the document being transported toward the image scanning station is first measured to find the length of the document, so that the following document is introduced into the image scanning station with timing varying with the length of the preceding document after the preceding document is treated and discharged. In a case that the following document passes past the scanning reference point just when the preceding document is discharged, the following document is moved backward to the scanning reference point, but if the following document does not reach the scanning reference point at that time, it is further forwarded to the appropriate image scanning station, consequently to shorten the interval of transporting the preceding and following documents, thus speeding up the image processing operation.
摘要:
A clamp is used for clamping a paper feed tractor to a support shaft at a predetermined distance from another paper feed tractor. The clamp comprises a semi-cylindrical elongated clamp guide member which is cantilevered from a frame of the paper feed tractor, and a cylindrical clamp member rotatably mounted about the clamp guide member. The clamp guide member has a clamping inner peripheral surface adapted to complementarily engage the support shaft, a first outer peripheral surface, a second outer peripheral surface having a radius of curvature larger than the first outer peripheral surface and a sloped outer peripheral portion joining the first and second outer peripheral surfaces. The clamp member has a clamping inner peripheral surface adapted to complementarily engage the support shaft, a first inner peripheral surface, a second inner peripheral surface having a radius of curvature larger than the first inner peripheral surface, and a sloped inner peripheral portion joining the first and second inner peripheral surfaces, such that the clamp member is rotatable between a clamping position and a release position.
