The invention discloses a structure for improving the reliability of a high-resistance region in a metal gate process. High resistance is formed at the top of shallow trench isolation with a metal gate. A first transverse distance is formed between the high resistor and the adjacent pseudo active region, and the first transverse distance is used for adjusting the pattern density of the pseudo active region and enabling the height and the uniformity of shallow trench isolation to meet the requirements. The interlayer film has a first thickness and the first thickness satisfies a process requirement of a contact hole passing through the interlayer film. The interlayer film is divided into a first interlayer sub-film and a second interlayer sub-film. The high resistance is between the first and second interlayer sub-films, the first interlayer sub-film having a second thickness. And the second thickness is used for adjusting a second longitudinal distance between the high resistor and the adjacent pseudo active region, so that the minimum distance between the high resistor and the adjacent pseudo active region meets the voltage withstanding requirement under the condition that the first transverse distance is not increased. The invention also discloses a method for improving the reliability of the high-resistance region in the metal gate process.

This invention provides a torque angle logic control method and control system, a rolling connection device, a storage medium, and an electronic device. The method includes: employing an independent angle control method, setting a target angle for the motor spindle during the rolling process, acquiring the real-time angle of the motor spindle during the rolling process, and controlling the operation of the motor spindle of the rolling connection device based on the real-time angle and the target angle; when the real-time angle reaches the set target angle during the rolling process, the motor spindle of the rolling connection device automatically reverses and exits. This invention effectively ensures the stability and consistency requirements of the product and meets the expected service life of the product.

This utility model relates to a welding and fixing fixture for a 5G chassis cabinet, including a mounting plate on which a front fixing component, a right fixing component, a rear fixing plate, and a left fixing plate are mounted. The front fixing component includes a front drive device and a front fixing plate. The front sidewall of the front fixing plate is connected to the front drive device, and the front fixing plate is inserted into an opening and abuts against the inner and outer sidewalls of the bent section. The rear fixing plate abuts against the rear sidewall of the rear panel. The right fixing component includes a right drive device and a right fixing plate. The right sidewall of the right fixing plate is connected to the right drive device, and a first protrusion is provided on the upper part of the left sidewall of the right fixing plate. The lower sidewall of the first protrusion abuts against the upper sidewall of the right panel. The left fixing plate abuts against the left sidewall of the left panel. It also includes an upper pressure plate placed on the top plate. This welding and fixing fixture ensures that the length, width, and height dimensions of the cabinet are not affected by welding throughout the entire welding process, ensures that the mounting openings of the cabinet can stably install components and seal them after welding, and ensures the waterproof performance of the cabinet.

This invention provides a numerical simulation method for parametric design of an autoclave. The autoclave includes a vessel body with an opening at one end and a lid disposed at the opening of the vessel body. First autoclave teeth are evenly spaced along the circumference of the opening in the vessel body, and second autoclave teeth are evenly spaced along the circumference of the edge of the lid. The first and second autoclave teeth abut against each other along the axial direction of the vessel body to close the opening. The numerical simulation method specifically includes the following steps: Step S1: Obtain the temperature distribution of the autoclave using the Fluent temperature calculation module in ANSYS; Step S2: Optimize the fillet size at the root of the autoclave teeth using the Direct Optimization module in ANSYS to obtain the fillet with the minimum equivalent stress and maximum fatigue life under the corresponding initial dimensions; In Step S2, calculate the equivalent stress and fatigue life at the fillet of the autoclave using the Static Structual module in ANSYS based on the temperature distribution.

This invention provides a carbon source dosing device for wastewater treatment, comprising a pipe and a fixed box fixedly installed on the outer side of the middle position of the pipe. A storage box is mounted on the top of the pipe via a support rod. An inner cavity communicating with the pipe is opened inside the fixed box, and a rotating wheel is rotatably installed inside the inner cavity. A delivery pump is fixedly connected to the bottom end of the storage box, and a one-way valve is fixedly connected to the bottom end of the delivery pump. The one-way valve is fixedly connected to the inner cavity. By fixing the pipe in a wastewater delivery pipeline, wastewater can enter the interior of the pipe, and the delivery pump discharges liquid carbon source into the inner cavity, allowing the liquid carbon source to be fully mixed with the wastewater. The carbon source dosing device for wastewater treatment provided by this invention, when applied to wastewater treatment pipelines, makes carbon source dosing in wastewater treatment more convenient and efficient, and is not affected by the size of the wastewater treatment tank. Compared with existing carbon source dosing devices, its efficiency is greatly improved.
