3results about How to "Avoid problems such as leakage" patented technology

The present disclosure provides a laser-welding-facilitating light-emitting diode and a preparation method thereof, and belongs to the technical field of optoelectronic manufacturing. The light-emitting diode comprises a substrate, a light-emitting structure, a light-transmitting insulating layer, and a welding spot. The light-emitting structure and the light-transmitting insulating layer are both located on a bearing surface of the substrate, the light-transmitting insulating layer is located on a side of the light-emitting structure and connected with a side wall of the light-emitting structure, and the welding spot is located on a surface of the light-transmitting insulating layer away from the substrate and electrically connected with the light-emitting structure. A projection of the welding spot on the bearing surface of the substrate is at least partially located outside a projection of the light-emitting structure on the bearing surface of the substrate. Since the projection of the welding spot on the bearing surface of the substrate is at least partially located outside the projection of the light-emitting structure on the bearing surface of the substrate, when laser welding is adopted, a laser beam can irradiate the welding spot from the back surface of the substrate through the light-transmitting insulating layer, so that damage of the light-emitting structure caused by the laser beam can be avoided, and problems such as current leakage of the light-emitting diode can be avoided.

The utility model relates to the field of bathroom, disclose the regulator and closestool. The regulator includes: the connecting pipe, including the first pipe section and the second pipe section of series connection setting, the pipe orifice of first pipe section and second pipe section two mutually divergent orientation opposite and eccentric arrangement, first pipe section is used for with the butt joint of sewage pipe, and the lateral wall of first pipe section is equipped with the mounting portion, the connecting seat is used for with sewage pipe link, and the connecting seat is the annular structure, and the outside of first pipe section is covered, and the connecting seat has the limit portion, and along the axial direction of first pipe section, and the limit portion is equipped in the side of mounting portion close to second pipe section, and the axial limit of mounting portion is limited, and at least one of limit portion and mounting portion is annular structure. Utilize the eccentric arrangement of first pipe section and second pipe section, combine the characteristic that first pipe section can rotate 360 degrees, and only through the rotation can adjust the distance of second pipe section pipe orifice and closestool wall surface, thereby adapts to a variety of pit distance demand, thereby can reduce the independent model number of closestool.

The present application relates to a kind of vertebral body distraction device.The device includes pedicle screw, support component, fixed component and the distraction component connected with pedicle screw along the axial direction;Distraction component includes two support plates, two support plates are spaced apart along the radial direction of pedicle screw;Support component is provided with installation channel, support component is used to be inserted between two support plates, to open and support two support plates;Fixed component is used to be inserted in installation channel, to open and support support component.By inserting support component between two support plates, fixed component is inserted in installation channel, to open two support plates, i.e., the hollow distraction component is converted to solid in the present application, improve the stability of distraction component, so as to avoid using bone cement to increase the stability of distraction component, and then avoid the leakage problem caused by bone cement in injection process, improve the reliability of vertebral body distraction device.
