    • The present invention relates to a microwave oven. According to the present invention, a fixed heater 41 is installed on a ceiling of a cavity 31 of a microwave oven, and a pivotable heater 43 is installed to pivot upward and downward on its lower end in the cavity 31. When the pivotable heater 43 has been pivoted downward on its lower end, a grill 45 on which an object to be heated is seated is horizontally installed between a lower surface of the fixed heater 41 and an upper surface of the pivotable heater 43. A micro-switch 51, which will be pushed by the grill 45 and thus generate an actuating signal for pivoting the pivotable heater 43, is installed on a side surface of the cavity 31. According to the present invention, since the fixed and pivotable heaters 41 and 43 heat upper and lower surfaces of the object, respectively, and the pivotable heater 43 is pivoted according to whether the grill 45 is mounted or detached, it is possible to cook the object faster and more conveniently.
    • 微波炉本发明涉及一种微波炉。 根据本发明,固定加热器41安装在微波炉的空腔31的天花板上,并且可枢转加热器43安装成在其空腔31的下端上下转动。 当可枢转加热器43在其下端已经向下枢转时,其上放置有待加热物体的格栅45水平地安装在固定加热器41的下表面和可枢转加热器43的上表面之间。 将由格栅45推动并因此产生用于枢转可枢转加热器43的致动信号的微型开关51安装在空腔31的侧表面上。 根据本发明,由于固定和可枢转加热器41和43分别加热物体的上表面和下表面,并且可枢转加热器43根据格栅45是否安装或拆卸而枢转,因此可以将 对象更快更方便。

    • A tension mask assembly of a flat CRT is provided. The tension mask assembly includes a tension mask, which is placed to be opposite to a phosphor screen formed at an inner surface of a panel a predetermined distance from the phosphor screen and which serves to discriminate colors of electron beam; an aperture grill, which serves as an electron beam transmitting hole and which is formed on an effective surface of the tension mask having a slot or a dot shape; a rail which is supported by applying a predetermined tension to both ends of a long side part or short side part of the tension mask; a support bar, which supports both ends of the rail by being arranged in a direction that crosses with the rail and which has a support spring and a tamper wire disposed thereon; and a tension controlling member, which has a different rate of thermal expansion from the support bar and which is placed in a longitudinal direction against a side wall of a support bar.
    • 提供了一种扁平CRT的张力罩组件。 张力罩组件包括张力掩模,该张力掩模被放置成与荧光屏的内表面形成的荧光屏相对,距离荧光屏预定距离,用于区分电子束的颜色; 用作电子束透过孔的孔格栅,其形成在具有槽或点形状的张力掩模的有效表面上; 轨道,其通过对张力掩模的长边部分或短边部分的两端施加预定的张力而被支撑; 支撑杆,其通过沿与轨道相交的方向布置并支撑轨道的两端,并且具有支撑弹簧和设置在其上的防拆电线; 以及张力控制构件,其与支撑杆具有不同的热膨胀率,并且相对于支撑杆的侧壁沿纵向放置。
