  • Publication number: 20180115059
    Abstract: A radio-wave transmitting cover is configured to be arranged in the path of the radio wave of a radio-wave radar device. The thickness of the cover is set to a reference thickness at a reference position where the incident angle of the radio wave from the radio-wave radar device is 0°. The reference thickness is set to a value obtained by multiplying half of the wavelength of the radio wave by an integer. In the area around the reference position, the thickness of the cover is gradually changed such that the greater the distance from the reference position, the greater becomes the difference by which the thickness of the cover is larger than the reference thickness.

  • Patent number: 8107731
    Abstract: A text input device receives, in its information input circuit, a letter indicating a destination of transmission as information on the destination of transmission. The text input device stores, in its word-finder with learning function, an input text and an output text in a state correlated with the information on the destination of transmission or its attribute. The text input device in its text learning circuit controls a change in storage caused by correlating an input text matched to a text entered with the information on the destination of transmission or its attribute stored and coincident with the information on the destination of transmission or its attribute entered. When a text matched to the text entered is output, the text input device in its text converter takes out and outputs at least one output text stored.

  • Publication number: 20090112537
    Abstract: A location expression detection device extracts a location expression contained in an object text and determines one of the candidate places when the extracted location expression has a plurality of candidate places. A location expression information storage section stores correspondence of location expressions against locations. A location expression extraction section extracts a location expression from an object text and determines whether the extracted location expression has plural candidate places with reference to stored contents. An object text characteristic word extraction section extracts a characteristic word in the object text. A compared text search section searches for a compared text by using at least one of the plural candidate places and/or the characteristic word. A location expression identification section determines one of the candidate places based on information related to the searched compared text.

  • Publication number: 20080189367
    Abstract: A user-to-user communication system allows users to chat with each other by sending messages via a computer. The computer also includes a chatbot with which the users can chat; that chatbot generates response messages automatically. The computer keeps a history of messages sent by the users, infers users' interests from the content of the messages they send, matches users with similar interests, and presents the matched users as suitable chat partners. In inferring users' interests, the computer also considers message sent to the chatbot, so that a user can be matched with suitable partners even before the user has accumulated an extensive history of communication with other users.

  • Publication number: 20040207025
    Abstract: The invention provides a data processor realizing high-speed reading of an on-chip nonvolatile memory and improvement in defect repairing efficiency. For a nonvolatile memory, nonvolatile memory cells each having a split-gate structure including a memory transistor part of an ONO structure and a selection transistor part for selecting the memory transistor part are employed. The gate withstand voltage of the selection transistor part can be lower than that of the memory transistor part, so that it is convenient to increase reading speed. A specific storage region which can be read by a resetting instruction of the data processor is assigned to a storage region in the nonvolatile memory, and repair information and the like is stored in the specific storage region. An internal circuit to which the repair information is transferred replaces a normal storage region instructed by the repair information with a redundant storage region.
