Abstract: A cam-driven wire mesh-type electrospinning apparatus and a use method therefor are provided. The cam-driven wire mesh-type electrospinning apparatus includes the following components: a high-voltage (HV) power supply unit, a wire mesh-type spinneret, a fiber receiving device, a cam unit, and a solution supply unit. The positions and connection relationships of all the components are as follows: any end of the wire mesh-type spinneret is connected to the HV power supply unit, and the other end of the wire mesh-type spinneret is connected to the cam unit; the wire mesh-type spinneret is installed on the solution supply unit; and the fiber receiving device is positioned right above the wire mesh-type spinneret. The cam-driven wire mesh-type electrospinning apparatus may induce a solution to be uniformly distributed on a wire mesh plane, and adjust the density of jet flow and the distribution position of the jet flow.

Abstract: A semiconductor device is provided. The semiconductor device includes a bottom epitaxial layer, a gate stack formed over the bottom epitaxial layer, the gate stack including a work function metal (WFM) layer, a channel fin formed on the bottom epitaxial layer, a first interlayer dielectric (ILD) layer formed in a gate landing area over the gate stack, a second ILD layer formed in an area other than the gate landing area, and a WFM encapsulation layer formed between the first ILD layer and the second ILD layer, and formed on sidewalls of the gate stack.

Abstract: A file reading method includes: sending, by the application entity, a read request to a file system; when the application entity receives a first error response returned by the file system, determining, by the application entity, a file source of the target file and obtaining the target file from the file source; and sending, by the application entity, a write request to the file system, where the write request is used to instruct the file system to re-store the target file according to a replacement storage path.

Abstract: The present disclosure is for a pile-free parking management system and method comprising: an information manager which receives parking sensing information and locking information, and determines if a vehicle is properly parked and returned. The system comprises a plurality of sensing units each with a sensor and a sensing object installed onto and paired with a parking location and a vehicle. These sensing units are activated only when the sensor is aligned with the sensing object within a predetermined proximity of each other. Either the sensors and/or the sensing objects are installed at a parking location in a strategic and organized fashion. This system and method aim to maximize vehicle-parking capacity, and ensures orderly parking at the same time.
