  • Publication number: 20060011887
    Abstract: A novel liquid-crystalline ionic conductor, which is useful in the electric, electronic, chemical and bioengineering fields, as an anisotropic reaction solvent, ionic conductor, electric field-responsible conductor or the like, and a method for producing the same, is provided. The liquid-crystalline ionic conductor is obtained by mixing an organic molten salt with a-liquid-crystalline organic molecule or a liquid-crystalline inorganic molecule, which comprises a moiety miscible to the organic molten salt and a moiety that shows liquid-crystalline orientation, thereby forming a liquid-crystalline ionic conductor, wherein the organic molten salt is assembled to the liquid-crystalline molecule.

  • Publication number: 20050251557
    Abstract: Providing a new contents delivery method that is suitable for community networks and reduces leaks of personal information. Presentities indicating channels for information delivery are formed on presence service, and virtual channel communication terminals corresponding to their presentities are logically formed on an information delivery server. Thereby, contents are transmitted and received between the information delivery server and user communication terminals, and among the user communication terminals as if the contents were transmitted and received between a presentity indicating a channel and a presentity indicating a user. During contents transmission and reception, the need to exchange address information among users is eliminated, making it possible to prevent leaks of personal information.

  • Patent number: 5006795
    Abstract: A charged beam radiation apparatus includes an auxiliary charged beam emitting mechanism, a main charged beam emitting mechanism, a secondary electron detector, and a computer as a controller. The auxiliary charged beam emitting mechanism emits an auxiliary charged beam of a given acceleration voltage onto a predetermined portion of an electronic device to be measured. The main charged beam emitting mechanism emits a main charged beam of an acceleration voltage lower than that of the auxiliary charged beam onto the predetermined portion and the vicinity of the predetermined portion. The secondary electron detector detects secondary electrons generated from a portion irradiated by the main charged beam. The controller measures a change in a secondary electron signal from the secondary electron detector.

  • Patent number: 4928010
    Abstract: An arrangement for observing a surface using a charged particle beam irradiated on the surface of a specimen and detecting secondary electrons emitted. An exciting device produces a strong magnetic field substantially perpendicular to the surface of the specimen. Secondary electrons are extracted from a bottom or side surface of a recess, such as a through hole formed in the surface of the specimen, by an interaction between the emitted secondary electrons and the strong magnetic field. A focusing lens is arranged so as to focus the charged particles at a point on the specimen, even in the presence of a strong field. Thus, a secondary electron image on the surface of the specimen can be sharply obtained to thereby observe a secondary electron image at the bottom surface or side surface of the through hole.

  • Patent number: 4851768
    Abstract: In a characteristic test apparatus for an electronic device, a number of voltage supply beams are radiated onto predetermined irradiation positions of the electronic device placed on a sample table. In addition, a potential measuring beam is radiated onto a number of irradiation positions including the predetermined irradiation positions of the voltage supply beams. A secondary electron signal based on the potential measuring beam is detected to measure a potential. When the irradiation position of the potential measuring beam coincides with that of the voltage supply beam, the voltage supply beam is controlled to adjust a potential at the irradiation position to a set value by controlling, e.g., an acceleration power source for the voltage supply beam. When the irradiation position of the potential measuring beam is different from that of the voltage supply beam, a potential at this position is measured.
