  • Publication number: 20070178837
    Abstract: Proposed is a technique for implementing data communication and distance measurement even in a case where data communication and distance measurement share the physical layer. A wireless communication apparatus includes a radio unit and a distance measuring unit. The radio unit performs communication using a frame that includes at least a data period for transferring data and a beacon period for transmitting a beacon. The distance measuring unit utilizes the beacon period to measure the distance from the wireless communication apparatus to a target object whose distance is to be measured.

  • Publication number: 20070040326
    Abstract: A sheet supplying unit having no need to place a great many skew sensors and enabling printing apparatus to simplify structure and to reduce cost. The sheet supplying unit moves a skew sensor to a most left sensor position in which the table sensor detected that the print medium exists, detects the upper edge of print medium, and executes a skew detection; in the case that the print medium is narrow, moves a skew sensor, detects the upper edge of print medium, and executes a skew detection; in the case that a position of skew sensor does not place at a position keeping a predetermined margin at the inside of the print medium, moves skew sensor to the inside of the print medium and executes again an inclination detection; or according to print medium width and skew sensor width, changes a skew judgment quantity.

  • Publication number: 20060044470
    Abstract: An image pickup apparatus which is capable of interrupting a data searching process quickly without detecting a user pressing a search interruption button. A system controller circuit carries out a searching process for searching least one desired data from a plurality of data stored in a nonvolatile memory or a memory card. When a change-of-status of the image pickup apparatus is detected, for example, when a shutter button has been pressed halfway, the system controller circuit interrupts the searching process and executes an interruption process.

  • Publication number: 20050151980
    Abstract: A dimension measurement method includes: irradiating a measurement mark with light, the measurement mark being formed on a sample on which a pattern to be measured is formed, the measurement mark comprising measurement patterns of the same shape as at least part of the pattern to be measured, the measurement patterns being arranged in a matrix constituted of measurement pattern columns which are repetitively disposed with a predetermined space in the direction of an arbitrary measurement direction which would provide a measurement target dimension of the pattern to be measured, the measurement pattern column being composed of the measurement patterns disposed with a predetermined period in the direction perpendicular to the measurement direction, and the light being fallen from the measurement direction; detecting reflected diffracted light from the measurement mark to measure intensity thereof; calculating a theoretical value of the intensity of the reflected diffracted light from a plurality of candidate va

  • Patent number: 6737658
    Abstract: A first beam radiation is effected by uniformly radiating an electron beam on a vicinity of an underlying mark formed on a sample. The underlying mark is formed of a material with an emission efficiency of secondary electrons different from that of the other part of the sample. Thus, a surface of the sample is charged. A second beam radiation is effected by radiating an electron beam under conditions different from those of the first beam radiation, thereby scanning the mark. Secondary electrons from the surface of the sample are detected to determined the mark position. On the basis of the mark position, an alignment exposure is effected.

  • Patent number: 6715821
    Abstract: A mounting assembly for a first ornamental molding (2), comprises a second molding (10) independent of the first ornamental molding (2) and integrally fixed to and along the periphery of a window glass (1), and a molding clip (6) for holding the first molding (2). The molding clip (6) is fixed to the second molding (10 upon a molding process of the second molding. The molding clip (6) includes a body portion (17) defining therein a space for receiving an engagement portion (29) of the first molding, an engagement pawl (18) disposed on the inside of the body portion and adapted to engage with the engagement portion (29) of the first molding, and a flange (19) formed on the outside of the body portion and enclosed in the second molding (10) so as to fix the molding clip (6) to the second molding (10). The molding clip (6) is adapted to be positioned in a gap between the periphery of the window glass and a window frame (11) of a vehicle body by placing the window glass (1) on the window frame (11).

  • Patent number: 6657203
    Abstract: A sample has a first mark and a second mark formed in a layer upper than the first mark on a Si substrate. The first and second marks are arrange such that they do not have an overlapping area in a direction in which relative positions of the first and second marks are measured. The sample is scanned with an electron beam, detecting a first scattered-electron signal from the sample on a line including the first mark, and a second scattered-electron signal from the sample on a line including the second mark. Based on the first and second scattered-electron signal, representative positions of the first and second marks are obtained, and a positional misalignment amount of the first and second marks is further obtained.

  • Patent number: 6628380
    Abstract: A jig for inspecting the appearance of small parts with an optical microscope, the jig is equipped with a base, having an upper flat surface which becomes a mounting stage of the optical microscope, and is also provided with a member for moving the upper flat surface at least in a direction approximately parallel to a direction of an optical axis of an objective lens of the optical microscope in order to focus the optical microscope on an inspection portion of the small parts mounted on the upper flat surface. The jig is also equipped with an inspection-object supporting portion, provided with a member for supporting the small parts at the predetermined portion on the base. Furthermore, the jig is equipped with reflecting mirrors which have a mirrorlike surface with an inclined angle of approximately 45 degrees to the upper flat surface of the base.

  • Patent number: 5949076
    Abstract: A charged beam applying apparatus comprises a column at least having a charged beam generation section and optical system for controlling the charged beam and a chamber for holding a specimen in place which is exposed with the charged beam. At least one inner portion of the column is formed of a specific material whose an atomic number is equal or less than 22. When a contamination is cleaned off in the column through the utilization of an oxidation effect, an oxide film is sometimes formed inside the column. The electric charging of the oxide film causes a beam control error. The specific material such as the metal of the atomic number causes very much less such error. This is because such specific material involves less emission of secondary electrons and less electric charging in the oxide film formed.
