    • A gas insulated switchgear includes a transformer mounting body; a bushing mounted on the transformer mounting body; and a main circuit conductor. The main circuit conductor includes a first main circuit conductor which is connected to a circuit breaker and is located in the bushing and a second main circuit conductor which is connected to the first main circuit conductor. An insulator extends below the lower end of the transformer mounting body and toward the vicinity of the connection between the first main circuit conductor and the second main circuit conductor, in a region where the first main circuit conductor is located in the transformer mounting body. A ground shield is arranged in the insulator, and extends below the lower end of the transformer mounting body and above a coupling portion between the transformer mounting body and the bushing.

    • An angle measuring device 2 is configured to detect an angle formed between a measured line LX connecting a first position PL and a second position PR and a predetermined reference plane. The angle measuring device 2 includes: a case 10; a first pointing mechanism 30L for pointing the first position PL; a second pointing mechanism 30R for pointing the second position PR; moving mechanisms 60L and 60R that allow at least one of the first and second pointing mechanisms 30L and 30R to be movable; and a turning member angular scale mark 72 that indicates a moved amount of at least one of the first and second pointing mechanisms 30L and 30R by the moving mechanisms 60L and 60R. The moving mechanisms 60L and 60R move the first pointing mechanism 30L and the like so that a line segment connecting the first pointing mechanism 30L and the second pointing mechanism 30R includes the measurement reference plane or becomes parallel to the measurement reference plane.
    • 角度测量装置2被配置为检测在连接第一位置PL的测量线LX和第二位置PR与预定参考平面之间形成的角度。 角度测量装置2包括:壳体10; 用于指示第一位置PL的第一指示机构30L; 用于指示第二位置PR的第二指示机构30R; 允许第一和第二指示机构30L和30R中的至少一个可移动的移动机构60L和60R; 以及通过移动机构60L,60R表示第一和第二指示机构30L,30R中的至少一个移动量的转动构件角度刻度标记72。 移动机构60L,60R使第一指示机构30L等移动,使得连接第一指示机构30L和第二指示机构30R的线段包括测量基准面,或变得平行于测量基准面。

    • A loudspeaker includes a first bar magnet having a longitudinal direction, a second bar magnet having a longitudinal direction parallel to the longitudinal direction of the first bar magnet, a third bar magnet forming a second magnetic gap between the first bar magnet and the third bar magnet, a diaphragm arranged to vibrate in a vibrating direction, a case accommodating the first bar magnet, the second bar magnet, the third bar magnet, and the diaphragm , and the voice coil fixed to the diaphragm and located in the first and second magnetic gaps. The second bar magnet has a longitudinal direction parallel to the longitudinal direction of the first bar magnet, and has both ends in the longitudinal direction. The third bar magnet has a longitudinal direction parallel to the longitudinal direction of the first bar magnet, and has both ends in the longitudinal direction. The diaphragm is located between the first and second bar magnets and between the first and third bar magnents. The case is made of non-magnetic material and holds an outer periphery of the diaphragm. The case forms a first space surrounded by the case, one of the both ends of the second bar magnet, and one of the both ends of the third bar magnet. The case forms a second space surrounded by the case, another one of both ends of the second bar magnet, and another one of both ends of the third bar magnet. First and second sound holes are provided in the case and communicate with the first and second spaces, respectively. The loudspeaker is thin but outputs large sounds.
