Abstract: A conductive member is adapted to be attached onto a living tissue to detect a bioelectrical signal. A retainer retains the conductive member on the living tissue. A lead member is partly brought into contact with the conductive member to lead out the bioelectrical signal to a connector. A waterproof sheet covers the lead member in a watertight manner, while exposing a portion of the lead member from which the biological signal is led out.

Abstract: An error detecting/correcting circuit 9 in a digital broadcast receiving device calculates a error rate from the error amount for the amount of input information. A controlling part 15 converts the error rate into the C/N ratio as a receiving signal quality and indicates it on a screen of a TV receiver 5 or other indicator 18. In this method, after digitally demodulating the received digital broadcasting signal, the error rate is obtained by an error detecting part 9 and the error rate is converted into the receiving signal quality for indication. Therefore, compared with the reception performance indication based on the input level such as the AGC voltage, the method is high both in precision and in stability. The receiving signal quality can be detected only while receiving a digital broadcasting signal, so with reference to the converted receiving signal quality in antenna bearing adjustment, a digital broadcasting signal can be surely received without confusing it with an analog broadcasting signal.

Abstract: A portable satellite broadcast signal antenna apparatus for manually transporting a satellite signal converter. The apparatus includes an antenna device for receiving the satellite broadcast signals, a device for adjusting the angle of the antenna device with respect to a predetermined plane for aligning the antenna device with a satellite, and a housing defining an interior space for receiving the satellite signal converter and the angle adjusting device therein and having an exterior surface bearing the antenna device.
