    • A light separating element designed to have parallel first and second external surfaces, a first polarizing film disposed on the first external surface and arranged to reflect a first portion of a first component in a first direction and transmit a second portion of the first component and all of a second component in a second direction. Further, a second polarizing film can be disposed on a second external surface which reflects a first portion of the second component in a third direction and transmits a second portion of the first and second components in a fourth direction. Further, the first portion of the second component is reflected by the second polarizing film to strike the first polarizing film. The first polarizing film transmitting a first portion of the second component in a fifth direction or a reflecting surface disposed on the second external surface and arranged to reflect a second portion of a first component and all of a second component in a third direction toward the polarizing film. The first portion of the second component is transmitted by the polarizing film in a fourth direction and a second portion of the second component and the second portion of the first component are reflected in a fifth direction toward the reflective surface. The second portions of the first and second components traveling in the fifth direction are reflected by the reflective surface in a sixth direction toward the polarizing film and the second portions of the first and second components traveling in the sixth direction are transmitted by the polarizing film in a seventh direction.
    • 一种设计成具有平行的第一和第二外表面的光分离元件,设置在第一外表面上并被布置成在第一方向上反射第一部件的第一部分并且透射第一部件的第二部分并且全部 在第二方向上的第二部件。 此外,第二偏振膜可以设置在第二外表面上,第二外表面沿第三方向反射第二部件的第一部分,并且在第四方向上透射第一和第二部件的第二部分。 此外,第二分量的第一部分被第二偏振膜反射以撞击第一偏振膜。 所述第一偏振膜在第五方向上透射所述第二成分的第一部分,或者设置在所述第二外表面上的反射表面,并且被布置成将第一成分的第二部分和第三成分的所有第三成分朝向偏振 电影。 第二部件的第一部分在第四方向上被偏振膜透射,第二部件的第二部分和第一部件的第二部分在朝向反射表面的第五方向上反射。 第一和第二部件沿第五方向行进的第二部分在第六方向上被反射表面反射到偏振膜,并且沿第六方向行进的第一和第二部件的第二部分通过偏振膜传播 第七个方向。

    • A magnetic core (2) is formed so as to be vertically thin and segmentable into an upper segment (3) and a lower segment (4). An inner portion (2a) and two outer portions (2b), (2b) of the magnetic core (2) are interconnected so as to form a closed magnetic circuit. A substrate (9) is inserted between the two outer portions (2b), (2b), while the inner portion (2a) is inserted into a through hole (10) of the substrate (9). A scroll pattern coil (11) is formed on each of front surface (9a) and rear surface (9b) of the substrate (9) outside the through hole (10). Further, a bobbinless winding coil (13) is inserted into an annular space between the inner portion (2a) and the through hole (10).
    • 磁芯(2)形成为垂直薄且可分割成上段(3)和下段(4)。 磁芯(2)的内部部分(2a)和两个外部部分(2b),(2b)互相连接形成闭合磁路。 基板(9)插入在两个外部部分(2b),(2b)之间,而内部部分(2a)插入基板(9)的通孔(10)中。 在通孔(10)外部的基板(9)的前表面(9a)和后表面(9b)的每一个上形成有涡旋形图案线圈(11)。 此外,将无轴绕组线圈(13)插入到内部(2a)和通孔(10)之间的环形空间中。
