  • Patent number: 8416704
    Abstract: A radio communication system of a frequency hopping system, which carries out time division multiplex by TDMA and carries out communications while changing over two or more frequencies with respect to a radio link, wherein radio resources are efficiently utilized by establishing a plurality of radio links. A first communication apparatus periodically transmits control data by a frame cycle and a second communication apparatus which is a communication partner thereof receives the above-described control information during standby and secures synchronization in timing of frames and slots and timing of frequency hopping. Communication signals between both communication apparatuses and control information are overlapped in a slot to establish radio links. Once radio links are established in a plurality of slots other than a slot for transmitting control information, control is performed such that the control information is overlapped in the slots in which a radio link is established.

  • Patent number: 7883271
    Abstract: In a rolling bearing including an oil supply unit for supplying lubricating oil stored in a tank by a pump via a nozzle which is made to open in an annular space defined between an inner ring and an outer ring, the nozzle is made to open in a space between an inner circumferential surface of a case and the inner ring, and the inner circumferential surface of the cage is formed into a surface in which an inside diameter of the cage is reduced gradually in a continuous or intermittent fashion from an axial center portion towards at least an end portion lying on a side where the nozzle is inserted, whereby a lubricating oil dropped on to the inner circumferential surface of the cage is caused to flow towards the axial center portion by virtue of centrifugal force generated by the rotation of the cage, so as to prevent the lubricating oil from flowing out to the outside of the bearing unit.

  • Patent number: 7555030
    Abstract: The invention provides a frequency hopping method for switching a hopping carrier frequency in a predetermined hopping pattern based on a hopping carrier table, in which there is provided intermittent receiving means for starting carrier frequency designating means every constant cycle to give a command for receiving the control channels of opposed radio base stations. In the case in which a hopping order in a hopping carrier table is skipped by n to carry out switching every intermittent receiving cycle in an intermittent receiving operation, an intermittent receiving cycle is set in such a manner that the n and a total number m of hopping carrier frequencies in the hopping carrier table have a prime relationship with each other.

    Abstract: In a time division multiplex access (TDMA-TDD) type wireless communication system in which a communication operation is carried out between a first communication apparatus (mother appliance) and a second communication apparatus (child appliance), and since a slot diversity mode is selected while considering power consumption on the side of the second communication apparatus, the wireless communication system performs such a wireless communication having a higher wireless quality. Based upon a power supply remaining energy capacity on the side of the second communication apparatus, and an electromagnetic wave environment when a wireless signal is received, a slot diversity mode is selected.

  • Patent number: 7356104
    Abstract: A radio communication apparatus and method employs frequency hopping in a predetermined pattern based on a hopping carrier table. An intermittent receiving section activates a carrier frequency designating section every constant cycle to give a command for receiving the control channels of opposing radio base stations. In the case in which a hopping order in a hopping carrier table is skipped by n to carry out switching every intermittent receiving cycle in an intermittent receiving operation, an intermittent receiving cycle is set in such a manner that the n and a total number m of hopping carrier frequencies in the hopping carrier table have a prime relationship with each other. The electric field strength of a carrier frequency in a spare carrier list is measured by the intermittent receiving operation and an interference counter of a spare carrier is increased or decreased corresponding to a frequency at which the electric field strength exceeds or does not exceed a predetermined threshold.
