Abstract:
A client connected to a communication network performs an access request to an object. An application server performs an application by an actual object according to the client request. An object pool connected to the client and the application server pools a proxy object corresponding to the actual object and holds the actual object management information. The application server notifies the object pool of an event according to the status change of the application. The object pool automatically updates the actual object management information according to the notification of the event from the application server.

Abstract:
Provided are a stereoscopic display device and stereoscopic display system, and a stereoscopic display device and glasses for stereoscopic video image observation, which are capable of reducing flicker attributable to the influence of a fluorescent lamp while preventing increase in crosstalk. Specifically, provided is a stereoscopic display system provided with: a stereoscopic display device which displays left-eye video images and right-eye video images alternatively in terms of time, the left-eye video images and right-eye video images being based on inputted left-eye video signals and right-eye video signals; and glasses for stereoscopic observation which comprise left-eye shutter and right-eye shutter configured to adjust quantities of light passing through the glasses toward the respective left and right eyes, and with which the left-eye video images and right-eye video images are observed. The stereoscopic display system is further provided with: an ambient light detecting unit which detects ambient light surrounding the system; and a shutter controlling unit which, so that changes in quantities of ambient light entering the respective left and right shutters can be reduced, controls quantities of light passing through the respective left and right shutters.
Abstract:
The present invention provides an information collection apparatus, an information collection method, and a program capable of collecting information from information resources on a network effectively as well as a search engine that searches the information resources collected. An information collection apparatus of the present invention that collects information from information resources on a network includes an extraction unit that acquires data from an information resource via the network to extract a link-destination address included in the data, a calculation unit that calculates, by comparing each link-destination address with a collection rule describing a set of addresses qualified for a collection target, a score for each link-destination address that reflects a distance from the set to a link-destination information resource indicated by the link-destination address, and a judgment unit that judges whether the link-destination information resource is to be included in the collection target or not in accordance with the score calculated for the link-destination information resource.
Abstract:
A transmission cable that has three signal lines, and in which there is little unwanted radiation noise, is provided. In a section that is perpendicular to the longitudinal direction of the differential transmission cable, the distance between any two signal lines of the three signal lines is equal to a predetermined value. The differential transmission cable is twisted in its longitudinal direction. The differential transmission cable further includes a dielectric core line, and the signal lines are formed on the surface of the dielectric core line. In the differential transmission cable, the signal lines are formed in a helix in the longitudinal direction of the dielectric core line.
Abstract:
A laminated glass (10) has a structure in which seven sheet glasses (20) and six PVB resin layers (30) are laminated alternately. A laminated region from a transparent surface (10a) on one side to 4.0 mm comprises two 0.7 mm-thick glass layers formed of two sheet glasses (20), one 0.8 mm-thick glass layer formed of the portion (20c) of one 1.5 mm-thick sheet glass (20) positioned in the laminated region, and two adhesion layers (30) with thicknesses of 1.3 mm and 0.5 mm. Each of the adhesion layers is interposed between the glass layers and is adhered to the glass layers. The laminated region with a depth of 4.0 mm from a transparent surface (10b) on the other side also has the same laminated structure as that in the above laminated region.
Abstract:
A CAD apparatus designing patterns of a printed board. The apparatus includes a signal wiring pattern detecting unit for detecting a signal wiring pattern, and a guard ground detecting unit for tracing the signal wiring pattern along the longitudinal direction thereof, in order to detect whether or not a guard ground exists within a distance from the signal wiring pattern to a predetermined first discriminant value, identify a non-guard ground section within the distance to the first discriminant value, and to detect whether or not a guard ground exists within another distance from the signal wiring pattern to a second discriminant value, which is larger than the first discriminant value. The apparatus also includes a return path judging unit for judging an error of guard ground when no guard ground exists within the distance to the second discriminant value, thereby quickly checking a return path without mistake.
