    • A broadcast receiving apparatus includes a first tuner configured to receive a broadcast wave from a specified broadcasting station, a second tuner configured to perform a frequency search for receivable broadcasting stations, a power supply unit configured to supply power to the first tuner and the second tuner, a traveling state detection unit configured to determine if a vehicle is moving or is stopped, a reception state detection unit configured to detect a reception state of a currently-received broadcast wave, and a control unit configured to control the first tuner, the second tuner, the power supply unit, the traveling state detection unit, and the reception state detection unit. The control unit causes power to be supplied to the second tuner and causes the second tuner to perform a frequency search while the vehicle is traveling, and when it is determined that the vehicle has stopped, the control unit turns the power supplied to the second tuner on and off in accordance with the reception state of the broadcast wave.
    • 广播接收装置包括:第一调谐器,被配置为从指定的广播电台接收广播波;第二调谐器,被配置为对可接收广播电台执行频率搜索;电源单元,被配置为向第一调谐器和第二调谐器 ,配置为确定车辆是否正在移动或停止的行驶状态检测单元,被配置为检测当前接收到的广播波的接收状态的接收状态检测单元和被配置为控制第一调谐器的控制单元,第二调谐器 调谐器,电源单元,行驶状态检测单元和接收状态检测单元。 所述控制单元使得所述第二调谐器供电,并使所述第二调谐器在所述车辆行驶时进行频率搜索,并且当确定所述车辆停止时,所述控制单元将提供给所述第二调谐器的电力 根据广播波的接收状态开启和关闭。

    • An objective lens holder of the present invention includes: (i) a cavity, having an entrance and an exit, which guides, to an objective lens, an incident light beam entering the entrance, the exit being provided on a side of the cavity where the objective lens is housed; and (ii) an aperture having an opening for limiting, to an effective diameter of the objective lens, a beam diameter of the incident light beam passing through the cavity. The cavity is surrounded with internal wall surfaces facing each other so that space between the internal wall surfaces gradually increases from the opening of the aperture toward the entrance or the exit. This makes it possible to provide a highly rigid objective lens holder that allows high speed read/write operations.
    • 本发明的物镜保持器包括:(i)具有入口和出口的空腔,其引导到物镜进入入口的入射光束,该出口设置在腔的一侧, 容纳物镜; 和(ii)具有用于限制物镜的有效直径的入口的孔,该入射光束通过腔体的光束直径。 空腔被彼此面对的内壁表面围绕,使得内壁表面之间的空间从孔的开口朝向入口或出口逐渐增加。 这使得可以提供允许高速读/写操作的高度刚性的物镜保持器。
