  • Publication number: 20240356620
    Abstract: A communication device includes a communication unit and a control unit. The communication unit performs wireless communication using at least one of a plurality of beams. The control unit acquires service communication quality corresponding to quality requested on a service. The control unit obtains, by estimation, an estimated communication quality achievable by the communication unit, based on a radio wave propagation environment. Even in a case where a beam quality of a non-currently working beam, a beam which is not being used for wireless communication, is higher than the beam quality of a currently working beam, which is being used for wireless communication, the control unit maintains the communication by the currently working beam in a case where the estimated communication quality is the service communication quality or more. Where the estimated communication quality is below the service communication quality, the control unit determines switching of the beam.

  • Patent number: 7199788
    Abstract: The present invention provides a pointing input device, which sequentially outputs pointing position data indicating a pointing input position and push detection data from a push by the same pen or finger used for a pointing input. The pointing input device includes a display panel for displaying any pointing input information and an optical touch panel. The optical touch panel detects the pointing input in an input operation area, through which a display area is visible, and outputs the pointing position data. Piezoelectric substrates are attached to a transparent protective plate protecting the top surface of the display panel. When an operator pushes the transparent protective plate disposed at the lower part of the optical touch panel while carrying out the pointing input, the piezoelectric substrates output electric signals by which the push is judged. Then, the push detection data is outputted with the pointing position data.

  • Patent number: 6343792
    Abstract: A shaft seal having a high abrasion resistance is disclosed, by which the leakage of the gas from the high-pressure side to the low-pressure side can be reduced. In the shaft seal, flexible leaves are multi-layered to form a ring shape. The shaft seal is mainly arranged around the rotation shaft of a gas turbine or the like. The relevant turbine comprises a casing, a compressor, a rotation shaft, moving blades attached to the rotation shaft, and stationary blades attached to the casing in a manner such that the stationary blades face the moving blades, wherein the shaft seals are provided between a plurality of stationary blades and the rotation shaft wherein the leaves of each shaft seal contact the rotation shaft. Under the rated operating conditions, the top ends of the leaves slightly separate from the surface of the rotation shaft due to the dynamic pressure generated by the rotation of the rotation shaft.
