Abstract:
PROBLEM TO BE SOLVED: To provide a wireless communication network including a base station (10) and a wireless unit (UE). SOLUTION: The wireless unit (UE) requests a connection with a base station (10) by transmission of a preamble within time slots designated by the base station (10). The disclosed preambles are Walsh Hadamard code symbols, repeated a number of times so as to have the same length as a cell-specific scrambling code. The wireless unit (UE) requesting a connection pseudo-randomly selects one time slot and one Walsh Hadamard code symbol available, scrambles a bitstream obtained from the code symbol and transmits it to the base station (10). The base station (10) descrambles the received input bitstream and de-interleaves the symbol. The symbol is applied to a correlator (104, 126, 136) to determine the transmitted preamble.

Abstract:
PROBLEM TO BE SOLVED: To adjust ultra high-speed bi-directional data transmissions between a central unit and a plurality of remote units, through distinct twisted pair transmission lines that share a binder. SOLUTION: Specifically, periodic synchronized uplink and downlink communication periods are provided so as not to overlap with each other. The uplink and downlink communication periods for all of the wires that share the binder are synchronized. With this arrangement, all of the ultra high-speed transmissions within the same binder are synchronized, and time division duplexed such that downlink communications are not transmitted when overlapping with the transmission of uplink communication. In some embodiments, quiet periods are provided to separate the uplink and downlink communication periods. The invention described may be used, in conjunction with a wide variety of modulation schemes, including both multi-carrier and single carrier transmission schemes. It is compatible with the existing systems and has particular advantages for ultra high-performance systems. COPYRIGHT: (C)2006,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a slurry for polishing which has less of the conventional defects and is improved which is used for chemical mechanical polishing (CMP) to be used for manufacturing a semiconductor integrated circuit, and to provide a polishing method using the same. SOLUTION: The slurry for polishing has a composition which uses colloidal silica instead of the conventional aerosol silica for the material of an abrasive, and uses a corrosion inhibitor while not using an oxidant which has been conventionally used. For wafer interconnection fabrication, a damask inlay method is employed. In the polishing method, a damask inlay structure and a polishing pad are prepared. The slurry is applied on the interface between the structure and the pad, and polishing is performed by a chemical mechanical polishing apparatus using the polishing parameters of the apparatus to remove at least part of a metal layer.

Abstract:
PROBLEM TO BE SOLVED: To obtain a device for capturing images improved by a digital camera. SOLUTION: When a user obtains an image by operating a switch, the digital camera provides an external sound or activity for allowing the simulation of the obtaining of the image. Actually, a component is added as if the image were obtained. The operation of a timing unit 22 is initiated by the start of the switch. Without an input by the user, an actual image is obtained after the elapse of a pre-selected time determined by the timing unit 22. The digital camera periodically obtains images by the operation of the timing unit switched on. The images are transferred to a processing unit 12, where a pattern recognition program 12A checks the preselected features of the thus obtained images, smiling faces, etc., of a subject. After the preselected features are discriminated, the digital camera stores images having the preselected features. The invention is applicable to the photographing of children.

Abstract:
PROBLEM TO BE SOLVED: To provide a low-current motor protecting apparatus formed with a switch chamber, and having an oblong metal housing formed with an opening end. SOLUTION: The housing has an opposite flange laterally extending from the opening end. Part of spaced lid (18a, 18b, 18a', 18b') is located on the flange by a gasket (16) located between the housing and the part of the lid, having a central opening and electrically insulating, and clamped to the flange. The part of the lid is maintained at a correct location by spring clips (22, 22') attached to the lid, and formed with a recessed ceramic heater sheet disposed in the switch chamber having a contact shelf (18f) with a space for accommodating a ceramic heater (20) receiving a supplied contact force.

Abstract:
PROBLEM TO BE SOLVED: To disclose a method that prevents cloning of a mobile communication device by downloading a boot image onto the device and generating a device-bound certificate (DBC). SOLUTION: A DBC includes an authentication code generated with a hashed message authentication code/algorithm and a key specific to a device. The method stores the DBC on a boot image to bind the boot image to the mobile communication device. A flash loader downloads a boot image (204), and calls a protected application (206). The protected application computes a DBC (208), optionally encrypts the DBC with a random key (210), and transfers it to the flash loader (212). The flash loader inserts the DBC into a DBC field (214), and loads the boot image into a flash memory of the mobile communication device (216). COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a device and method for games requiring the display of individual player information. SOLUTION: The game device has a display device, a game hub (10), and at least one game controller (15). Each console has a local display device (20). The local display device (20) has objects to be displayed normally only for use by a game controller user. For example, the objects to be displayed in card games are cards already distributed to a game controller device. The device on the game controller is used by the user to select the object to be displayed for continuing the game. COPYRIGHT: (C)2005,JPO&NCIPI
