Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To simplify calibration of camera parameters, and easily measure objects in a wide area, in a three-dimensional position measuring method and its equipment in which a plurality of cameras are used. SOLUTION: A plurality of cameras are so fixed on a jig that position measurement regions overlap in a wide area (S1). Outer/inner parameters of each camera in a camera coordinate system common to all cameras are obtained, and a transformation formula for obtaining a three-dimensional position of an object in the camera coordinate system by the principle of trigonometrical survey from positions on the image plane of the object of a plurality of the cameras is constituted (S2). A jig with a fixed camera and an assemblable jig which is provided with a plurality of characteristic objects in known positional relations in a measurement region coordinate system are arranged in the measurement region (S3).  The characteristic objects are measured with a plurality of cameras, and parameters for transforming the three-dimensional positions of the characteristic objects in the camera coordinate system by the transformation formula into the three-dimensional position in the measurement region coordinate system is obtained (S4). Finally, the three-dimensional position of a measurement object in a wide area is obtained from the parameters and the transformation formula (S5).

Title: Weft-length measuring apparatus for fragment loom
Inventor: MATSUZAKI KAZUHIKO
IPC: D03D47/36
Filed: 1988-12-24
Abstract: PURPOSE:To eliminate the application of load to the flying of weft and to prevent defective weft insertion by selectively integrating a ring holding a weft wound round a V-groove roller driven and rotated in the transport direction of the weft and forcedly introducing the weft into a nozzle while measuring the length of the weft. CONSTITUTION:A driving motor 18 is energized to rotate a V-groove roller 16 in the weft-transport direction shown by the arrow and, at the same time, a pump 26 is driven to eject air through a Vgroove 16a of the V-groove roller 16. A ring 17 holding a weft 8 wound round the ring and loosely fitting to the V-groove group is separated from the V-groove 16a by the air flow. When the ejection of air is started by a fluid nozzle 13 toward a warp opening part, a tension is applied to the weft 8 wound round the ring 17 to press the ring 17 against the circumferential groove of the V-groove roll 16 opposing to the air pressure blasted through the V-groove 16a. The ring 17 starts to rotate together with the V-groove roll 16 to unreel the weft 8 from the bobbin 15 and the weft is forcedly introduced into the fluid nozzle 13 which is controlled to eject the weft during a period corresponding to the measured length of the weft.

Abstract: PURPOSE:To expand a detection area by constructing the title apparatus so that a detecting device can be moved by devices for rotation, declination and elevation and running. CONSTITUTION:Far infrared rays recognized by a sensor element 22 of a pyroelectric infrared sensor 21 are transmitted as information to a terminal and the whole of a monitoring apparatus is moved by a running device 25. When a rotation instruction from the terminal is transmitted to a rotating motor 27, the rotating motor 27 rotates in the direction of instruction under a speed control. Moreover, the instruction from the terminal is received by a declination- elevation control unit 34. The declination-elevation control unit 34 extends or contracts a shaft 32 for moving the sensor vertically. Since the pyroelectric infrared sensor 21 is fitted to the shaft 32 by a plug 31 for fixing the sensor, it is declined and elevated with the shaft 32 for moving the sensor vertically.

IPC: G21K5/04
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To easily correct the positional shift of a generated electron beam and to obtain information on the shape and state of the electron beam by detecting secondary electron information obtained by a detector for detecting reflected electrons or secondary electrons and information derived from the shape of the electron beam formed based on secondary electrons obtained by the scanning of a mark by a deflector and/or information derived information on reflected electrons. SOLUTION: A mark 108 for adjustment is formed on a stage 107 and the stage 107 is driven so as to position the mark 108 for adjustment within a range possible to scan the mark by electron beam 102 in adjusting rectangular apertures 103 and apertures 105 for collective transfer to deflect the electron beam 102 and to scan the mark 108. Since the scanning starting position can be set to be a single position for all of the measurement of the rectangular apertures 103 and the apertures 105 for collective transfer for the control only for alteration, the starting position can be employed as a standard for measurement position.  Defined rotation degree and magnification error calculation can be carried out by specifying the degree of the difference of the positions of the gravity center of the respective apertures 105 from the standard position and the position of the gravity center of the rectangular apertures 103.

Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To improve the security of a network and a computer while maintaining stationary operation by providing a means which performs network set inspection by using a means simulating network communication. SOLUTION: An inspecting device 101a notifies an inspecting device 101b of a test start and a test table of a simulation packet to be transmitted by the device 101a (901). When the device 101b receives test start notice, the device 101b stores the test table in a test data storing part and also starts to capture the packet via a line controlling part (910). A repeater 102 relays the packet based on filtering information stored in data transmission and reception control information (905 to 907). For this reason, the device 101b can capture the packet (911 and 912). When the device 101b captures the packet, inspection results are described and the device 101a notifies the device 101b of a test end (902).

Title: Developing device
Inventor: NAKANO MASAO
IPC: G03G15/08
Filed: 1989-12-20
Abstract: PURPOSE:To prevent the generation of the lumps of a developer by independently disposing a sealing member and a bearing member and using respectively nonmagnetic metals for these members, thereby improving the sealability of the developer. CONSTITUTION:A revolving shaft 3 is held in tight contact with an inner sealing part 8 of an oil seal 6 fixed to the mounting hole of the side plate of a developer container 1 and revolves while rubbing with the sealing part 8. The oil seal 6 presses the revolving shaft 3 by a elasticity of rubber to seal the developer in the developer container 1. The sealing force of the oil seal 6 weakens when the pressure of the developer acts on the tight contact surfaces of the oil seal 6 and the revolving shaft 3, but a ring 7 consisting of the nonmagnetic metal is embedded in the oil seal 6 in this case and, therefore, the strong sealing force is maintained. The oil seal and a bushing do not receive the influence of the magnetic field in the developer container 1. The oil seal 6 does not, therefore, suck the developer and does not generate the lumps of the developer.
