Abstract: Disclosed is an equivalent friction coefficient measurement apparatus for a rolling bearing. The apparatus comprises a machine body, a rotary shafting, a sliding seat, a rotational velocity sensor and a data acquisition/processing/calculation/display system. The rotary shafting comprises a mandrel and two support bearings supporting the mandrel. The support bearings are configured as air-floating spindle assemblies or measured rolling bearings or the air-floating spindle assembly and the measured rolling bearing. The rotational velocity sensor is configured to monitor an angular velocity of gyration of the mandrel.

Abstract: Disclosed is a grinding disk kit for finishing rolling surfaces of bearing rollers, including a pair of coaxial first and second grinding disks; a front face of the first grinding disk includes a group of radially distributed linear grooves and transition faces for connecting the adjacent linear grooves; a front face of the second grinding disk includes one or more helical grooves and transition faces for connecting adjacent helical grooves; one bearing roller to be machined is distributed in each linear groove corresponding to each intersection of the helical grooves and the linear grooves during grinding machining; the rolling surfaces of the bearing rollers to be machined are respectively in contact with working faces of the linear grooves and the helical grooves corresponding to each intersection; and the bearing rollers to be machined translate along the linear grooves while rotating about the own axes under the friction.

Abstract: The present invention provides a method and apparatus for transmitting control signal of Resilient Packet Ring (RPR) Medium Access Control (MAC), including: encapsulating a control signal of RPR MAC interface to be transmitted into an RPR data frame of predefined format, and directly sending it to a receiving unit through a standard interface. In this invention, an RPR data frame of predefined format is utilized to transmit signals between an RPR MAC and a receiving unit, e.g., an RPR client, via standard interfaces, which may avoid the increase of unstable factors affecting signal transmission and hardware cost caused by the appending of hardware devices in the standard interfaces. Thus, the reliability of signal transmission is enhanced, and the hardware cost of communication system is reduced.

Abstract: The present invention discloses a protection switching apparatus for nodes in a Resilient Packet Ring (RPR) network, including: a first switching module, for receiving inner ringlet data and transmitting data to the outer ringlet; a second switching module, for receiving outer ringlet data and transmitting data to the inner ringlet; and when it is in a normal mode, each of the switching modules transmits the received ringlet data to the other switching module connected to itself, and the received ringlet data are transmitted through normal data paths; when protection switching is required and frame boundaries of data are reached, the first and second switching modules directly switch data paths within themselves, and transmit the received ringlet data through WRAP data paths. At the same time, a protection switching method for nodes in an RPR network is provided.

Abstract: A laminated dielectric block (3) is formed by laminating dielectric sheets (31) each having a conductive film formed on its one surface so as to constitute at least one filter (2). A radiation element (1) is provided so as to fix to the laminating dielectric block, wherein one electrode of the filter is electrically connected to the radiation element. The other electrode (22) of the filter is connected to a feeding terminal electrode (4) provided mounting face B (a face opposing to a circuit board) of the laminated dielectric block through a via-contact (33) and a wiring (34), not being exposed to the side face. As a result, an antenna with built-in filter of the structure where even if it is mounted on a circuit board, interference between an electronic circuit on the circuit board and the feeding terminal electrode of the antenna is prevented to improve the isolation characteristic and transmitting or receiving characteristic.
