Title: Metal covered carbon material and carbon-metal composite material using the metal covered carbon material
Inventor: UENO TOSHIYUKI
IPC: B22F1/18
Filed: 2008-09-16
Abstract: This invention provides a transition metal covered carbon material comprising a transition metal covering. In the transition metal covered carbon material, the adhesion between the transition metal and the carbon material is large, and the transition metal covering is less likely to be separated or eliminated during subsequent working. The transition metal covered carbon material is produced by depositing a compound containing a transition metal ion on the surface of a carbon material, heat treating the assembly to reduce the transition metal ion with carbon contained in the carbon material to form a transition metal as a simple substance. The transition metal is Fe, Co, Ni, Mn, Cu, or Zn. There is also provided a carbon-metal composite material using the transition metal covered carbon material, which has improved affinity for metal such as aluminum and has excellent mechanical strength and thermal conductivity.

Title: Image processing device, image processing method, data storage medium, and program
Inventor: NOMURA TAKEHIRO
IPC: G06T13/60
Filed: 2009-04-27
Abstract: In an image processing device (200), a storage unit (201) stores first paste area data (251) that show the position and shape of a first polygonal area to which a first texture image will be pasted, and second paste area data (252) that show the position and shape of a second polygonal area to which a second texture image will be pasted. An updater (202) disposes the shape of the first polygonal area and the second polygonal area in a virtual space so that a specified edge of the first polygonal area and a specified edge of the second polygonal area are present on the same straight line, and transforms the shape of the first polygonal area and the shape of the second polygonal area using an affine transformation. A generation and display unit (203) generates and displays an image in which the first texture image is pasted in the first polygonal area and the second texture image is pasted in the second polygonal area. The updater (202) repeats processing to transform the shape of the first polygonal area in a first period, and repeats processing to transform the shape of the second polygonal area in a second period.

Title: Transmission of signaling information for broadcast and multicast services
Inventor: VAYANOS ALKINOOS HECTOR
IPC: H04J3/16
Filed: 2005-02-10
Abstract: Techniques for transmitting signaling information for broadcast and multicast services are described. A base station transmits signaling information for each service in accordance with a schedule that includes a repetition period and a modification period. The signaling information is sent in each repetition period to allow wireless devices to quickly obtain this information. Changes to the critical signaling information are permitted at the start of each modification period, which is an integer multiple of the repetition period. Whenever the critical signaling information for a given service is changed in a given modification period, a notification indicator for the service is set in an entire preceding modification period to inform the wireless devices of the impending change. The wireless devices can detect the notification indicator being set in the preceding modification period and can retrieve the updated critical signaling information in the following modification period.
