Abstract: A road surface area detection device includes a normalized speed calculation portion configured to calculate a normalized speed based on a movement of a feature point in an image captured by a camera that is disposed in a vehicle; a determination range calculation portion configured to calculate a road surface determination range, which is indicated by a magnitude of the normalized speed, based on the normalized speeds of at least two feature points at different positions in a width direction of the vehicle in a predetermined central area where the vehicle is positioned in a center thereof in the width direction perpendicular to a vehicle traveling direction; and a road surface area identification portion configured to identify, as a road surface area on which the vehicle travels, a position in the width direction that includes the feature point whose normalized speed is within the road surface determination range.

Abstract: There are provided a calibration apparatus and method capable of obtaining a high-precision calibration result by taking out only feature points on a road surface from images captured by an in-vehicle camera which is a calibration target. A road surface range is estimated by using feature points appearing in an image(s) captured by a camera (a front camera 102 or a rear camera 103) that is not a camera on which the calibration is executed (a side camera 106); and the calibration is executed by using only feature points existing within the estimated road surface range from among the feature points appearing in an image(s) captured by the camera on which the calibration is executed.

Abstract: An electric connection box includes a base having a relay mounting portion on which a relay is configured to be mounted. The base has a component mounting portion on which a component is configured to be mounted at a lower position of the relay mounted on the relay mounting portion. The component mounting portion is disposed so that at least a part of the component mounting portion overlaps with an area of the base in which the relay is mounted in a plan view.

Abstract: An electric connection box includes a first base on which an electronic component is configured to be mounted, the first base having a first side surface portion and a second side surface portion, and a second base on which the electronic component is configured to be mounted, the second base configured to be assembled to the first base and having a first side surface portion and a second side surface portion. The first side surface portion of the first base faces the second side surface portion of the first base. The first side surface portion of the second base faces the second side surface portion of the second base. The first side surface portion of the first base has a guide rib. The first side surface portion of the second base has a guide groove.

Abstract: A display system of electronic manual which allows easy identification of wirings. The display system of electronic manual is provided with a storage device in which stored is an electronic manual provided with a wiring diagram described in a vector image description language and constituted so as to allow reading by a browser program. In response to user's selection of a component on the wiring diagram displayed on a display, a wiring display system highlights the selected component. In response to user's operation of selecting the highlight, the wiring display system highlights wirings extending from the selected component. Moreover, while the wiring is highlighted, in response to user's operation of selecting gray display, the wiring display system switches the elements other than the selected component and the wirings extending from the component on the wiring diagram displayed on the display to be displayed in weak gray.

Abstract: The present invention relates to improvement of the unpleasant taste characteristic of potassium salts without adversely affecting the salty taste of the potassium salts and provides a method for reducing sodium contents in foods and drinks without reducing salty taste of the foods and drinks and also provides sodium-reduced foods and drinks. The present invention relates to a taste-improving agent for a potassium salt or a potassium salt-containing food or drink, and the agent contains a phthalide as an active ingredient.

Abstract: This invention discloses a hydrogenated oil flavor-imparting agent comprising vanillin and/or ethyl vanillin, and hydrogenated-oil-flavored oil and fat formed by use of the agent.

Abstract: This invention provides a method for identifying a purchaser who purchased content from which an illegal copy was produced. A provider system encrypts a content purchased by the purchaser using a public key of a purchaser system and sends the encrypted content to the purchaser system. The purchaser system creates a digital signature of the content with the use of a private key of its own and embeds the created digital signature into the received content. When an illegal copy is found, the provider system verifies the digital signature, embedded in the illegal copy as a digital watermark, to identify the purchaser who purchased the content from which the illegal copy was produced.

Abstract: An optical disk substrate formed of an aromatic polycarbonate resin obtained by a reaction between an aromatic dihydroxy compound and a carbonate diester and in which the content of undissolved substances that emit light by irradiation with light having a wavelength of 380 nm and have a size of 30 &mgr;m or greater is 100 pieces or less per kg of said resin, and a molding material therefor. According to the present invention, there can be provided an optical disk substrate in which the number of white spots that occur in the passage of a long period of time is very small and the reliability of writing and reading of information is highly stable.

Abstract: A keyword-based information retrieving method which accepts a group of keywords entered from a user when the user makes a request for a search, sets a particular keyword within the group of keywords entered from the user as a main keyword, sets the remaining keywords other than the main keyword as additional keywords, modifies the additional keyword having a low relativity to the main keyword to a keyword having a high relativity, and conducts a search requested by the user using the group of modified keywords.
