    • A lens meter having an optical measuring system which can measure optical characteristics of a progressive lens includes a memory means which stores the optical characteristics of each measuring point measured in a range from a far vision region to a near vision region by the optical measuring system, a distinguishing means which compares the optical characteristics of each measuring point stored in the memory means and distinguishes whether the measured points belong to a progressive band or areas located in both right and left sides of the progressive band, a display means which displays a result of the distinguishing means. With this structure, the optical characteristics of each measuring point can be measured ranging from the far vision region to the near vision region by the optical measuring system, and the results are stored in the memory means. Next, by means of the distinguishing means, the optical characteristics of each measuring point are compared and distinguished whether the measured points belong to the progressive band or the areas located in both right and left sides of the progressive band. This distinguished result is displayed by the display means. Thus, the measuring position of the progressive lens can be easily recognized, and thus the near vision power can be accurately measured.
    • 具有可以测量渐进透镜的光学特性的光学测量系统的透镜计包括:存储装置,其通过光学测量系统存储从远视区域到近视觉区域的范围中测量的每个测量点的光学特性, 比较存储在存储装置中的每个测量点的光学特性的区别装置,区分测量点是属于逐行频带还是位于渐进频带左右两侧的区域;显示装置, 区别手段。 利用该结构,可以通过光学测量系统测量各个测量点的光学特性,从远视区域到近视区域,并将结果存储在存储装置中。 接下来,通过识别手段,对每个测量点的光学特性进行比较和区分,测量点是否属于逐行频带或位于渐进频带左右两侧的区域。 由显示装置显示该区别结果。 因此,可以容易地识别渐进式镜片的测量位置,从而可以精确地测量近视力。

    • The invention offers a superconducting coil that has the shape of a pancake formed by winding a superconducting conductor. The superconducting conductor is composed of a tape-shaped (Bi, Pb)2223-based superconducting wire and a tape-shaped thin-film RE123-based superconducting wire that are electrically connected in parallel with each other. The coil generates only a low voltage in the steady-operation state, limits the generated voltage to a low level even in a state where an external disturbance enters for some reason, and is therefore less susceptible to quenching. Consequently, the coil can be operated stably in both states. The invention also offers a superconducting conductor to be used to form the coil.
    • 本发明提供一种超导线圈,其具有通过缠绕超导导体形成的薄饼形状。 超导导体由彼此并联电连接的带状(Bi,Pb)2223基超导线和带状薄膜RE123基超导线构成。 线圈在稳定运行状态下仅产生低电压,即使在由于某种原因导致外部干扰进入的状态下也将发电电压限制在低电平,因此不易于淬火。 因此,能够以两种状态稳定地操作线圈。 本发明还提供一种用于形成线圈的超导导体。
