Abstract: A subject for the invention is to provide a positive-electrode material, which has high capacity and high output and is inhibited from suffering a decrease in output with repetitions of charge and use. The invention provides a positive-electrode material for lithium secondary battery, which comprises a secondary particle of a lithium/transition metal composite oxide containing boron and/or bismuth, and wherein the atomic ratio of the sum of boron and bismuth to the sum of the metallic elements other than lithium, boron, and bismuth in a surface part of the secondary particle is from 5 times to 70 times the atomic ratio in the whole secondary particle.

Abstract: In a peer-to-peer network system, a first network terminal sends a request message to a host terminal. The host terminal receives this request message and extracts from this message an IP address of the first network terminal. A second network terminal also sends a request message to the host terminal, and the host terminal receives this request message, too. The host terminal sends a reply message to the second network terminal, where the host terminal has the IP address of the first network terminal contained in this reply message. The second network terminal extracts from the reply message the IP address of the first network and, based on this extracted IP address, starts a peer-to-peer communication with the first network terminal.

Abstract: A vehicle-use bearing device having a double row rolling bearing fitted around an outer peripheral surface of a hollow shaft portion of a hub wheel, wherein a held portion between an axially intermediate position and a vehicle outer side in the hollow shaft portion of the hub wheel is axially held between the axially intermediate position of an outer ring shaft portion of a constant velocity joint and the vehicle outer side so that a cup-shaped cylindrical portion of an outer ring of the constant velocity joint is free of contact with a caulked portion in the hollow shaft portion of the hub wheel at the shaft end on the vehicle inner side in order to connect the hub wheel with the constant velocity joint without a clearance, whereby an excessive preload which can affect a rolling performance of the double row rolling bearing is not imparted on the bearing.

Abstract: The number of sessions of a stack of a verification target machine is verified by connecting such verification target machine through a network with a verifier machine for verifying the number of sessions of the stack of the verification target machine; virtually generating an IP address to thereby produce at least one virtual machine in the verifier machine; and establishing a virtual session between the virtual machine and the verification target machine using a packet capture based on three-way handshake of TCP/IP. This enables advanced network verification on the software basis without needing expensive hardware.

Abstract: In a construction in which a double row rolling bearing and a constant velocity joint are mounted to a hub wheel, a fixing ring fixedly mounted to a vehicle-outer side opening of the hub wheel is sandwiched between a vehicle-outer side end face of an outer ring shaft of the constant velocity joint and a bolt integrally mounted to the shaft in the axial direction, thereby coupling the outer ring of the constant velocity joint to the hub wheel. In this case, a simple coupling operation only for mounting the bolt to the shaft suffices, and a pre-load that has been applied to the rolling bearing is maintained invariably.

Abstract: An object of the present invention is to provide a clutch device capable of providing a simple structure, greatly reducing power-application cost and component cost, reducing weight and improving convenience.

Abstract: A telephone exchanging apparatus 30 comprises a joined terminal table 341, a joined terminal table operating portion 352, and a reception side designating portion 355. The joined terminal table 341 stores terminal identification information that identifies a telephone terminal 40 that will join a conference. The joined terminal table operating portion 352 operates the joined terminal table 341 corresponding to joined terminal table operation commanding information. The reception side designating portion 355 designates the reception side of a speech packet transmitted from the telephone terminal 40. Since the joined terminal table 341 is operated by the joined terminal table operating portion 352, even if the number of people who join a conference increases, they can be easily added or deleted.

Abstract: This invention relates to a bending press for bending metal foils, comprising a mobile panel and a fixed panel. The fixed panel comprises two slots open on the lateral faces of the lower panel and symmetrical with respect to the transverse median plane of this fixed panel. The bottom of each slot is formed by the inner wall of a through bore made in the lower panel which extends over an angle close to 360°, in order to distribute the stresses due to the bending over a broader area. A safety stop is provided in the opening of each slot in order to limit the vertical displacement of the ends of the upper part of the lower panel.

Abstract: Magnetic recording media-are provided having separately textured data and read/write head landing zones. Separating these zones on the recording surface allows independent optimization of the topology to maximize both recording characteristics and mechanical durability. The landing or contact start stop zone has an average surface roughness greater than that of the data zone. Preferably, a transition zone extends between the contact start stop zone and the data zone, the transition zone varying between the two in average surface roughness. Preferably, the contact start stop zone is textured first, followed by the data zone, thereby ensuring uniform stiction performance. Texture machines for producing such zone texturing and texturing methods are also provided.

Abstract: Lower cost magnetic recording media and disk drive systems including an improved polymeric or polymeric-based disk substrate are provided by increasing the substrate thickness sufficient to provide mechanical rigidity comparable to that provided by an aluminum-based substrate of similar diameter and forming the CSS zone on the surface of the disk at the outer rather than inner diameter thereof, with a plurality of integrally formed projections extending from the disk surface for reducing heating during head takeoff and landing. The projections are coated with diamond-like carbon (DLC) and lubricant layers for reducing heating and friction during CSS operation and providing good tribological performance when utilized with a cooperating head slider having DLC contact pads.
