Abstract: A power head of a directional drill includes a main motor, gearbox, main shaft, active drill pipe, and water swivel. The gearbox has a driving shaft connected to the main motor and engaged with the main shaft via a gear. One end of the main shaft is fixedly connected to the active drill pipe, while the other end of the driving shaft links to an angle adjuster through the gearbox, enabling efficient toolface adjustment and braking of the main motor. The water swivel mandrel connects to the active drill pipe via a connecting shaft with an axial floating structure. A connecting sleeve near the water swivel forms a hexagonal sleeve sliding pair with the connecting shaft, preventing axial impacts on mandrel support bearings during drilling. This design enhances the service life of the bearings and reduces equipment repairs, improving the reliability and efficiency of the drilling process.

Abstract: A memory device may include processing circuitry connected to a ferroelectric transistor through a word line and a bit line. The ferroelectric transistor may include an interfacial layer between a gate electrode and a semiconductor layer, and a ferroelectric layer between the interfacial layer and the gate electrode. The processing circuitry may be configured to perform an operation to reduce disturb in the ferroelectric transistor by applying a mitigation pulse to the gate electrode of the ferroelectric transistor using the word line and then applying a program pulse to the gate electrode of the ferroelectric transistor using the word line. The mitigation pulse and the program pulse may have opposite polarities. A level of the program pulse may be sufficient to program a desired program state in the ferroelectric transistor. A level of the mitigation pulse may be sufficient to detrap electrons in the ferroelectric transistor.

Abstract: This application relates to a frame and an electronic device. The frame includes a first body and a second body. The first body includes a sealing surface, and the second body includes a flow-blocking part sunken toward one side. An extension surface of the sealing surface intersects the flow blocking part in a first direction. Because the flow blocking part is designed, in a plastic injection process, a pressure of injected plastic on the first body is reduced, to ensure that, after sealing processing is performed on the sealing surface of the first body, the plastic does not continuously flow in the first direction. This ensures sealing reliability of the sealing surface, improves sealing effect of the first body, enables the first body and the second body to be bound well, and ensures smooth manufacturing of the frame.

Abstract: A middle frame of an electronic device and the electronic device. The electronic device may include a handheld device, an in-vehicle device, a wearable device, a terminal device, or be connected to any one of a wireless modem, a cellular phone, a smartphone, a personal digital assistant, a computer, a tablet computer, a handheld computer, or the like. In embodiments, a display module of the electronic device is located inside a first mounting cavity, a sound channel is relatively isolated from the first mounting cavity, and the sound channel is not communicated with the first mounting cavity. In this way, the display module is also relatively isolated from the sound channel, so that a medium like oil inside the sound channel is prevented from contacting the display module. This greatly reduces a probability of occurrence of a yellow spot phenomenon.
