  • Patent number: 11960618
    Abstract: A computer implemented method searches data. A number of processor units generates a candidate search result using an index for a data source in response to a search query by a user, wherein the candidate search result comprises files accessible by the user based on access control information in the index. The number of processor units generates a completed search result with a set of the files from the candidate search result having a confidentiality level less than or equal to a threshold confidentiality level. The number of processor units determines whether the user has access to a file in the candidate search result in which the file has the confidentiality level greater than the threshold confidentiality level for the data source. The number of processor units adds the file to the completed search result in response to the file being accessible by the user in the data source.

In addition, the wavelength range ?? is substantially broad, i.e., satisfies ??/?max>10%. The coating [502] is a metamaterial having structural features smaller than the smallest operational wavelength, e.g., a nano-structured metamaterial such as a photonic crystal or a disordered nano-composite of a metal and a dielectric. In a preferred embodiment, the coating [502] is semi-continuous with a filling factor p between 70% and 75%. The dielectric may be, for example, air, vacuum, an electro-optic polymer, an optical gain material, an electro-active material, or a semiconductor.

  • Publication number: 20020012424
    Abstract: In a communication apparatus, it is judged whether or not received data can be outputted from a memory device to the exterior. When the received data can be outputted, the data is outputted from the memory device to the exterior, while data reception is continued. When the data reception is completed, a delete signal is sent back to a server and the relevant data stored in the server is erased. When received data cannot be outputted from the memory device to the exterior, it is judged whether the amount of the data exceeds empty capacity of the memory or not. When it is judged that the memory device reaches a memory overflow condition, the delete signal is not transmitted, and a warning is given to a user, and line is disconnected. When the memory device recovers from the memory overflow condition, the server is automatically called, transmission of data is requested, and a routine is repeatedly performed until the reception of one case data is completed.

  • Publication number: 20010028469
    Abstract: An object of the present invention is to solve the difficulty of entering e-mail addresses. To enter an e-mail address, the e-mail address is formed by entering a partial e-mail address with an input section and selecting a desired partial e-mail address with a selection section from a plurality of partial e-mail addresses stored in a storage section while observing a display section. Consequently, it is not necessary to enter the entire e-mail address by handwith the input section, so that this troublesome task can be eliminated.

  • Patent number: 5512993
    Abstract: Disclosed is an image heating device for a fixing device in image forming apparatus. The image heating device is provided with two heaters and an image fixing roller. The image fixing roller is heated by the two heaters, one having the heat distribution in the center and the other having the heat distribution in the end portion of the fixing roller. The heaters are alternately energized so that the power requirement is maintained limited. The energization time ratio of the heaters is suitably varied according to the sheet size in order to compensate the temperature loss in the end portions when the heating is conducted in the central portion only, or to reduce the temperature rise in the end portions, encountered when narrow sheets are consecutively passed, thereby preventing various drawbacks resulting from uneven temperature distribution on the fixing roller.
