    • Provided is a dielectric waveguide-path device in which it is possible to accurately, effectively, and less-noisily input and output an external signal.A refractive index n of a dielectric material is larger than a refractive index of the outside in a lateral direction X and/or a vertical direction Y perpendicular to an electromagnetic wave travelling direction Z, the inside of a waveguide-path has slow electromagnetic wave propagation velocity, compared to an area on the outside, the maximum dimension in the lateral direction and/or the vertical direction of the waveguide-path has a dimension which is specified by a formula below, an electric field lateral vibration mode curve in the waveguide-path and an electric field attenuation curve outside of the waveguide-path are continuous on both surfaces in the lateral direction and/or the vertical direction, and an electromagnetic wave is transmitted in the form of a cosine distribution or a sine distribution in the Z direction while being totally reflected by both surfaces. The dielectric waveguide-path device has an input electrode structure or an output electrode structure, in which a plurality of electrodes or electrode portions are arranged at regular intervals with respect to the Z direction, on the inside or the surface thereof. tan(ksa/2)=kf/ks, or tan(ksa/2)=−ks/kf. Here, ks: propagation constant of an electromagnetic wave low-speed area, kf: propagation constant of an electromagnetic wave high-speed area, and a: maximum dimension in the X direction and/or the Y direction of the waveguide-path.

    • A sailing ship includes a sailing unit, which comprises a hard sail assembly comprising a plurality of hard sail sections of wing-shaped hollow cross section vertically stacked so each, except the lowermost, fits on the one immediately below; a mast assembly comprising a plurality of mast sections of hollow cross section vertically stacked so each, except the lowermost, fits in the one immediately below; connecting members for connecting upper ends of the hard sail sections to upper ends of the mast sections located at the same level; first means for moving each mast section, except the lowermost, toward and away from the one immediately below; and second means for rotating the mast assembly around its longitudinal axis. Overlapping lengths between vertically adjacent mast sections are variably controlled so as to variably control overlapping lengths between vertically adjacent hard sail sections. Thus, the hard sail assembly vertically expands and contracts.
    • 帆船包括帆船单元,其包括硬帆组件,所述硬帆组件包括垂直堆叠的多个翼形空心横截面的硬帆部分,除了最下面之外,每个都紧紧配合在下面; 一个桅杆组件,包括垂直堆叠的多个桅杆部分,垂直地堆叠,每个桅杆部分除了最下部以外都配合在紧邻的下方; 连接构件,用于将硬帆部分的上端连接到位于同一水平面的桅杆部分的上端; 第一装置,用于移动每个桅杆部分,除了最下面,朝向和远离紧邻的一个; 以及用于使桅杆组件围绕其纵向轴线旋转的第二装置。 垂直相邻的桅杆部分之间的重叠长度被可变地控制,以便可变地控制垂直相邻的硬帆部分之间的重叠长度。 因此,硬帆组件垂直膨胀和收缩。
