摘要： A thrust screw includes a head, a first shank, a second shank, and a drilling member. The first shank and the second shank are arranged between the head and the drilling member. The second shank is provided with an external thread. The first shank is provided with a thrust member corresponding to the external thread. The thrust member includes two wing-shaped stop pieces and two flat portions. The two flat portions are formed on the two wing-shaped stop pieces respectively and correspond to the external thread. The two flat portions have an outer diameter greater than that of the external thread. The two flat portions of the thrust member stop a further screwing motion of the external thread.

摘要： A touch window including a first transparent substrate, a second transparent substrate, a first conductive film and a pad is provided. The second transparent substrate is disposed on one side of the first transparent substrate, and the area of the first transparent substrate is larger than that of the second transparent substrate. The first conductive film is disposed on the second transparent substrate and is located between the first transparent substrate and the second transparent substrate. The pad is disposed on the same side of the first transparent substrate as the second transparent substrate being disposed.

摘要： A slide cover unit including: a substrate board formed with guide slots and slide rails, each guide slot being formed as a curved path with a ridge point; an upper cover having slide channels and formed with a transverse slot, the slide rails of the substrate board being slidably inlaid in the slide channels; and at least one resilient member having a fixed end fixed at an outer end of the slot and a free end equipped with a roller member. The roller member is slidably inlaid in the transverse slot and the guide slots. When the upper cover is moved, the roller member is moved along the transverse slot and guide slots to extend or compress the resilient member. When the roller member passes over the ridge point, by means of the resilient restoring force of the resilient member, the upper cover can further automatically move relative to the substrate board to complete opening/closing operation.
摘要翻译： 一种滑动盖单元，包括：形成有引导槽和滑轨的基板，每个引导槽形成为具有脊点的弯曲路径; 具有滑动通道并形成有横向狭槽的上盖，所述基板的滑轨可滑动地嵌入滑动通道中; 以及至少一个弹性构件，其具有固定在所述狭槽的外端的固定端和具有滚动构件的自由端。 辊构件可滑动地嵌入横向槽和引导槽中。 当上盖移动时，辊构件沿着横向狭槽和引导槽移动以延伸或压缩弹性构件。 当辊构件通过脊点时，通过弹性构件的弹性恢复力，上盖可以进一步自动地相对于衬底板移动以完成打开/关闭操作。
