  • Publication number: 20040077362
    Abstract: A mobile body information system comprises a center system and a vehicle-mounted terminal device. The vehicle-mounted terminal device is configured to determine a density of communication areas of narrow area wireless base stations along a travel route of a vehicle based on a current position of the vehicle and installation data of the narrow area wireless base stations. When the density of communication areas is high, the vehicle-mounted terminal device is configured to recommend to a user a divided download format in which the information is intermittently distributed through a plurality of the narrow area wireless base stations while the vehicle is travelling. When the density of the communication areas is low, the vehicle-mounted terminal device is configured to recommend a batch download format in which the information is distributed through one of the narrow area wireless base stations while the vehicle remains in one communication area.

  • Patent number: 6718187
    Abstract: With a mobile telephone (10) set into a telephone holder (11), if a telephone call is received, rather than sounding an audible ringing, a head-up display (60) notifies the driver by a display (67) made in a peripheral vision region (64) outside of a central vision region (63) of the driver. The driver can respond to the incoming call only in the case in which the driving burden on the driver is small enough that, even without the aid of an audible ringing, the driver can notice the received-call display in only the peripheral vision region.

  • Patent number: 6717145
    Abstract: Mapping electron microscopes are disclosed in which the amount of charging of the specimen is controlled to between a minimum amount needed to view an image and a maximum amount beyond which a viewable image cannot be obtained that has low distortion or that does not result in specimen damage. Multiple irradiation-electron beams, or multiple segments of a single irradiation-electron beam, are directed to a specimen surface. The irradiation beams (or segments) are decelerated by a retarding voltage applied by a cathode lens and are incident on the specimen surface. The respective current and incident energy of each irradiation beam (or segment thereof) are controlled independently to a predetermined relationship so as to impart predetermined amounts of charging to different insulator regions of the specimen.

  • Patent number: 6661008
    Abstract: An electron-optical system, including irradiation means which irradiates a surface of a sample with an irradiating electron beam and observation means which focuses an observational electron beam emitted from the surface of the sample as an image on electron beam detection means. The observation means includes a plurality of electrodes. The electron-optical system further includes an accelerating electric field disposed between the surface of the sample and at least one of the plurality of electrodes so that the sample is biased to a negative potential, and so that the velocity of the observational electron beam that has just been emitted from the surface of the sample increases monotonically to a positive potential. The velocity of the observational electron beam that has been accelerated to the positive potential is reduced to the ground potential by another of the plurality of electrodes which form the observation means.

  • Publication number: 20030126974
    Abstract: A contents reproduction system includes a reproducing section to reproduce a content received via telecommunication when the receiving condition is in an acceptable state, and to reproduce one of recorded contents stored in a storage section when the receiving condition is in an unacceptable state. A preference discriminating section determines a preference of a user by examining at least one content selected by a user for reproduction. A contents selecting section selects one, as a reserve content, from the contents stored in the storage section in accordance with the preference and supplies the reserve content to the reproducing section for reproduction instead of the received content when the receiving condition is in the unacceptable state.
