Abstract: To effectively call in customers. Provided are a frame display unit that displays frames that respectively correspond to a plurality of tables arranged in a store on a screen of a store terminal 2, a vacant seat presence/absence change unit that, in a case where one frame has been selected from the frames displayed on the screen, changes vacant seat presence/absence information that is stored in a vacant seat presence/absence information DB 5b in correspondence with the selected frame to a content indicating that it is not vacant, a vacant seat status update unit that updates vacant seat status information that indicates what extent of vacancy is present in tables in a store stored in a vacant seat status information DB 5c on the basis of the vacant seat presence/absence information, and a vacant seat status providing unit that provides the vacant seat status information to a user terminal 3.

Abstract: There is a need for an object recognition apparatus for identifying multiple objects separately or collectively and a method therefor. An object recognition apparatus is configured to include: an image output section acquiring multiple object images and outputting an image; a detection section detecting the multiple object images in the image; a first identification section identifying the detected multiple object images; and a second identification section identifying the detected multiple object images collectively.

Abstract: The grease composition for constant velocity joints of the invention is characterized by comprising a lubricating base oil, a thickener, carbon black with a mean particle size of not greater than 500 nm, and an organic molybdenum compound. A grease composition for constant velocity joints according to the invention can achieve a highly satisfactory balance between anti-flaking, anti-seizure and anti-wear without using lead compounds, and can sufficiently maintain these properties with long-term use.

Abstract: A fire detecting/extinguishing apparatus according to the present invention is comprised of a fire detecting unit which monitors to detect a fire within a monitoring area, the fire detecting unit stepwise scanning in a vertical direction while scanning the fire monitoring area in the vertical direction at each step of the horizontal scanning; a water discharging unit having a water discharging nozzle for discharging water to the monitoring area, the water discharging unit being rotatable in the horizontal direction, the water discharging unit being directed toward a position of the fire based on the fire detection by the fire detecting unit; a swinging unit which swings the water discharging unit in the horizontal direction; and a casing in which the fire detecting unit and the water discharging unit are housed as a single unit. Further, the apparatus of the present invention includes a cover fixed to a side of the water discharging nozzle which is opposite to the side of the water discharging nozzle.

Abstract: A method of measuring an average particle size of granules. The method computes the average particle size on the basis of an n-order moment M.sub.n of an image of granules accumulated in a pile or of the image subjected to binarization or floating binarization. The method is capable of highly accurate and stable measurement on granules having many irregularities in the surface thereof and accumulated in a pile. The method can be used to continuously measure in real time the particle size of granules in a rotary tray of a rotary tray-type rolling granulating machine thereby adjusting the feed rate of a liquid binder to automatically control the particle size.
