  • Publication number: 20100295224
    Abstract: A strut mount allows a sufficient pre-compression to be applied to a rubber member without impairing the retaining force for the rubber member, thereby achieving improved durability of the rubber member. A pre-compression member (4) has an outer diameter that is smaller in the distal end side than in the proximal end side, and is press-fitted into the inner peripheral surface of an inner tube member (1).

  • Patent number: 7715345
    Abstract: The normalities of access points including antenna facilities thereof are confirmed. An access point includes a terminal function unit which has the transmission/reception functions of a radio terminal. A radio signal is transmitted from the terminal function unit to the signal processing unit of an access point through the antenna of the access point, and a process for the calling connection between the terminal function unit and a test server is executed through the antenna of the access point, and the antenna and signal processing unit of the access point (along a path). The normalities of the antenna of the access point and the access point, or the abnormality of any of them is judged in accordance with the success or failure of the calling connection.

  • Publication number: 20090170560
    Abstract: A receiver of a wireless base station that uses a simple mode to detect a failure is provided, and an SW 201 switches whether an input port of the receiver 133 is to be connected with an antenna 114 or to be terminated. An LNA (a low noise amplifier) 205 amplifies an input signal with a low distortion. SWs 202 and 203 switch between a first path which runs through the LNA 205 and a second path 204 which does not run through the LNA 205. An AGC AMP, the gain of which is controlled such that the output thereof is constant, amplifies the signal with the controlled gain. A base station control section uses the SW 201 to terminate the input port of the receiver so that thermal noise is input to the LNA 205.

  • Publication number: 20070217317
    Abstract: An optical disk device according to an embodiment of the present invention includes: an irradiating unit irradiating an optical disk with laser light; a photodetector split into at least two along a track direction of the optical disk and converting return light from the optical disk into an electric signal to output a detection signal; and a reproduction signal generating unit generating an RF signal based on the detection signal from the photodetector. The reproduction signal generating unit generates an RF signal in a header portion based on a detection signal from one of the at least two photodetectors split along the track direction or a detection signal from the other photodetector. An RF signal in a data portion is generated based on all of detection signals from the photodetector.
