摘要： A surface to serve as a surface under ultrasonic inspection has a roughness of 0.4 &mgr;mRa or less, and wherein all imperfections existing a controlled volume X corresponding to all cross sections of a raceway ring 1 assume a length of 0.2 mm or less as represented by the square root of areas of the imperfections. Accordingly, it is possible to provide a rolling bearing which does not become short-lived and obviates a concern about occurrence of cracking even when used in a harsh environment.

摘要： Provided is a cell exchanging device which realizes switching of an AAL2 connection level using an existing ATM switch, thus preventing deterioration of a transfer quality of other ATM cells. In an input-side ATM line corresponding section, provided are an ATM cell demultiplexing section 113-I-1 for extracting and separating only an AAL2 cell from an ATM cell, an AAL2 DMX 113-I-2 for converting from the AAL2 cell to an AAL2 partial fill cell, and an ATM cell multiplexing section 113-I-4 for multiplexing and packing the ALL2 partial fill cell and the ATM cell other than AAL2. Before entering to the ATM switch, a priority order of each ATM cell is determined based on class information presented in the ATM line corresponding section, and reading-out from the ATM cell multiplexing section is controlled. Similarly, also in an output-side ATM line corresponding section, at the time of a transfer to a transmission path, a priority order of each ATM cell is determined based on class information presented in the input-side ATM line corresponding section and a reading-out is performed.

摘要： In a variable length switch for exchanging CPS-packets by AAL2, an effective variable length packet switch without limiting capacitance of a switching section is provided when the CPS-packets are loaded on an ATM cell and exchanged. An interface section receives the ATM cell in which the CPS-packets are multiplexed and packed, disassembles the received ATM cell and demultiplexes and unpacks the CPS-packets loaded on the ATM cell. When output paths of the plurality of the CPS-packets are identical, the CPS-packets are transferred by multiplexing and packing them in the same connection. In an interface 110-1 to 110-N on a transmission side, a cell transferred from the switching section 100 is disassembled, and the CPS-packet are multiplexed and packed in a cell corresponding to an output path of the CPS-packets.
