    • The invention realizes an optical modulator which prevents occurrence of an edge breakdown and is improved in extinction characteristic and voltage resisting property. The optical modulator comprises an oxide film formed as a growth inhibiting film on a compound semiconductor substrate of a first conduction type, a double heterostructure including a clad layer of the first conduction type, a light absorbing layer and a clad layer of a second conduction type successively formed in an opening of the oxide film, and an embedding structure for covering over the entire double heterostructure. The optical modulator is characterized in that the carrier concentration of the clad layer of the first conduction type exhibits a continuous variation from the semiconductor substrate to the light absorbing layer or the carrier concentration of the embedding structure portion exhibits a variation from a low concentration to a high concentration.

    • A slide fastener stringer includes a row of helically coiled or zig-zag coupling elements of thermoplastic synthetic resin with a reinforcing core extending longitudinally therethrough. The coupling elements are secured to one surface of a stringer tape by sewing threads having portions running across and over upper legs of the coupling elements. Some of the coupling elements are cut off to provide an element-free space on the stringer tape. A terminal or endmost complete coupling element disposed adjacent to the element-free space has a free-ended connecting portion remote from a longitudinal edge of the stringer tape. To form an end of the slide fastener stringer, the free-ended connecting end portion of the terminal coupling element is fused to the stringer tape, and at the same time, the upper leg of the terminal coupling element is heated and pressed toward the stringer tape. A device for forming such a stringer end includes a stringer rest for supporting the end of the stringer, and a heating presser having a first surface for heating and pressing the free-ended connecting portion of the terminal coupling element against the stringer tape and a second surface for heating and pressing the upper leg of the terminal coupling element toward the stringer tape. The first surface projects beyond the second surface toward the stringer rest.
    • 拉链纵梁包括热塑性合成树脂的螺旋卷曲或锯齿状连接件的一排,其中纵向延伸穿过其中的加强芯。 联接元件通过缝合线固定在纵带的一个表面上,缝纫线具有穿过连接元件的上腿和上腿的部分。 一些耦合元件被切断以在桁条带上提供无元件空间。 靠近无元件空间设置的端子或最终的完整耦合元件具有远离桁条带的纵向边缘的自由端连接部分。 为了形成拉链条的端部,端子联接元件的自由端连接端部被熔接到桁条带上,同时将端子连接元件的上腿加热并朝向桁条 胶带。 用于形成这种纵梁端的装置包括用于支撑纵梁末端的纵梁架,以及具有第一表面的加热压板,该第一表面用于加热并将端子联接元件的自由端连接部分压靠在纵梁上, 表面,用于加热并将终端耦合元件的上腿压向桁条带。 第一个表面突出第二个表面朝向纵梁。
