  • Publication number: 20080120078
    Abstract: A modeling device is disclosed that easily projects characteristic information obtained from an object onto a differently-shaped object, even if the object, from which the characteristic information is obtained, has a complex shape. A modeling device in one embodiment of the present invention includes a virtually electrifying section to calculate an electric potential at a spot in a heart at the time when a predetermined voltage is applied to the heart, and a projecting section to project a fiber orientation onto a heart model created on the basis of shape information that is input to the input section. The projecting section specifies a spot to be a target of projection on the basis of the electric potential obtained by the virtually electrifying section. Use of the electric potential in specifying the spot makes it possible to easily project the fiber orientation onto any heart having complex and various shapes.

  • Patent number: 7243229
    Abstract: A computing system and an exclusive access control method are provided for preventing degraded performance of a network caused by exclusive access control, and for permitting a computer to exclusively access a storage area irrespective of whether a storage has an exclusive access control function. In the computing system in which a plurality of computers and an external storage device storing shared data are connected through a relay, exclusive access control is executed by a device other than the storage. Specifically, the relay having a virtualizing function is instructed to execute exclusive access control. The relay has information indicating whether a storage area on the storage is an exclusive access area, so that the relay determines based on this information whether an access request received from a computer requests an access to an exclusive access area, and executes exclusive access control when it is an access request.

  • Publication number: 20060255343
    Abstract: A semiconductor apparatus includes a substrate; and a plurality of semiconductor thin films formed on said substrate, each of said semiconductor thin films having a pn-junction, and electrodes of p-type and n-type for injecting carriers to the pn-junction, wherein said semiconductor thin films are formed so that all or a part of said pn-junctions are connected serially. As different from a semiconductor thin film constituted of a single pn-junction, the light emission with the invented semiconductor apparatus is the summation of the light emission intensities of the entire pn-junctions, so that the light emitting intensity can be increased largely.
