    • A television signal converter includes a CATV tuner having a channel converting function, a gain changing circuit for descrambling the output from the CATV tuner and the like, in order to convert a television signal such as a CATV signal formed by a scrambled video signal into a descrambled television signal of channel 3, for example. The descrambled channel 3 CATV signal outputted from the gain changing circuit includes noise in the reproduced audio signal since the audio carrier is influenced by gain changing. In the present invention, therefore, the audio signal is reproduced from an audio carrier extracted from the front stage of a gain changing circuit. Thus, the reproduced audio signal is released from noise caused by gain changing.
    • 电视信号转换器包括具有信道转换功能的CATV调谐器,用于对来自CATV调谐器的输出进行解扰的增益改变电路等,以将诸如由加扰视频信号形成的CATV信号的电视信号转换为 通道3的解扰频电视信号。 由于音频载波受增益变化的影响,从增益改变电路输出的解扰频道3 CATV信号包括再现的音频信号中的噪声。 因此,在本发明中,从从增益改变电路的前级提取的音频载波再现音频信号。 因此,再现的音频信号由增益变化引起的噪声释放。

    • A system control circuit is provided with a table storing portion. In the table storing portion, a table for a positioned-on-a-floor mode and a hung-from-a-ceiling mode, a table for upwardly-positioned, and a table for downwardly-positioned are stored. On each table, temperature of outside air and voltage supplied to each fan power supply are corresponded. In receipt of information indicating a positioned-on-a-floor state (angle=zero degrees) from an attitude detection sensor, the system control circuit selects the table for a positioned-on-a-floor mode and a hung-from-a-ceiling mode. In addition, the system control circuit obtains measured temperature data from a temperature sensor, and applies this measured temperature data to the selection table as a read-out address. As a result, voltage values regarding each fan power supply are read out from the selection table. The system control circuit instructs each fan power supply to drive the fans based on the read-out voltage values.
    • 系统控制电路具有表存储部分。 在台存储部分中,存储有用于位于地板模式和悬吊模式的桌子,用于向上定位的桌子和用于向下定位的桌子。 在每个工作台上,对应于每个风扇电源供给的外部空气和电压的温度。 在从姿态检测传感器接收到指示位于地面状态(角度=零度)的信息时,系统控制电路选择用于位于地板模式的表和从地板上挂起的 接通模式。 此外,系统控制电路从温度传感器获取测量的温度数据,并将该测量的温度数据作为读出地址应用于选择表。 结果,从选择表中读出关于每个风扇电源的电压值。 系统控制电路根据读出的电压值指示每个风扇电源驱动风扇。

    • Barometric-pressure data that a barometric pressure sensor outputs, and an air volume data that an air-volume sensor outputs are input into a system control circuit. The system control circuit is provided with a table storing portion. In the table storing portion, a control table is stored. The control table defines a voltage value to be added to a fan power supply set by a barometric-pressure value and an air-volume value. The voltage value to be added is voltage added to a normally set voltage value, and is set within a range from 0 (zero) V (volt) to 6 V, for example. The normally set voltage value is voltage set based on temperature detected by a temperature sensor, for example. In this case, the voltage value to be added is applied to voltage that is determined by the outside temperature and applied to the fan power supply.
