Abstract: Provided are a beveled light-emitting lamp bead, a beveled light-emitting lamp bead holder, a manufacturing method therefor, and a display device. The beveled light-emitting lamp bead holder includes a holder body and a metal holder embedded in the holder body, where the holder body is divided by the metal holder into a cup shield located on a top side and a support structure located on a bottom side, a cup bottom in the cup shield is provided with a chip mounting surface parallel to a cup rim top surface, a bottom portion of the support structure is provided with a soldering plane, the soldering plane is electrically connected to the chip mounting surface through the metal holder, and an inclination angle is formed between the chip mounting surface and the soldering plane.

Abstract: An apparatus and a method for executing a customized production line using an artificial intelligence development platform, a computing device and a computer readable storage medium are provided. The apparatus includes: a production line executor configured to generate a native form of the artificial intelligence development platform based on a file set, the native form to be sent to a client accessing the artificial intelligence development platform so as to present a native interactive page of the artificial intelligence development platform; and a standardized platform interface configured to provide an interaction channel between the production line executor and the artificial intelligence development platform. The production line executor is further configured to generate an intermediate result by executing processing logic defined in the file set and to process the intermediate result by interacting with the artificial intelligence development platform via the standardized platform interface.

Abstract: A train having a protection device with self-adaptive crashworthiness is disclosed, which relates to the technical field of safety protection of trains. The train includes multiple vehicles, a head vehicle is located at the head end of the train, and a head vehicle energy absorbing coupler mechanism is mounted at the front end of the head vehicle, each two adjacent vehicles are connected to each other by a middle vehicle energy absorbing coupler mechanism. An image acquisition mechanism and a radar detector are mounted at the head vehicle for monitoring whether there is an obstacle ahead the train, measuring distance and collision speed between the train and the obstacle, and for transmitting measured data to a processing center of the train, the processing center optimizes and adjusts impact force at the head vehicle energy absorbing coupler mechanism and the middle vehicle energy absorbing coupler mechanisms based on a collision situation.

Abstract: A self-heat-dissipation pressure-reducing valve includes: a heat-dissipation valve core, an upper valve deck, a guiding valve deck, a valve body, a heat-dissipation valve seat, an air guide hood, and a turbine-type heat dissipation device. The heat-dissipation valve core is formed by a valve core composed of a heat pipe, and valve core heat-dissipation fins. The heat-dissipation valve seat includes a valve seat pocket, a valve seat shell, heat pipes, and valve seat heat-dissipation fins. An outer circumferential surface of the valve seat pocket is wound with multiple heat pipes fixed to the valve seat heat-dissipation fins. The turbine-type heat dissipation device includes a fan shell provided at a medium inlet, and a turbine. The turbine is lashed by a medium to turn the fan shell, and wind is guided in one direction through the external air guide hood to implement heat dissipation.
