Abstract: A cross-coupling control method for moving beam of gantry machine tool is disclosed, which relates to the technical field of CNC machine tool control. The cross-coupling control method includes: Step 1: establishing a crossbeam dynamics model considering a ram on the crossbeam, and at the same time simplifying the model for an observer design; step 2: realizing a PID control parameter adjustment of motors at both ends in accordance with a method of parameter tuning of a unilateral servo control system; using a servo system with the same control parameters to jointly drive the crossbeam up and down, realizing the synchronous control and realizing PID control parameter tuning for both end motors. The disclosure not only reduces the synchronization error caused by the torsion of the crossbeam, but also solves the synchronization error caused by the asymmetric load on both sides, and improves the system robustness and stability.

Abstract: An unloading device and an unloading method for a gantry-type machining center beam guide rail is disclosed, which is used to be installed on a sliding plate assembly, comprising a first booster mechanism and a second booster mechanism. When a worm rotates and drives a worm gear to rotate, an axial displacement can be generated by the worm gear along a worm gear shaft to push the retaining sleeve assembly, and an unloading force generated acts on a first mounting bracket. An unloading bolt of the second booster mechanism is connected with a press plate through threads, the unloading bolt is rotated to generate an axial displacement, and a second sliding block is pressed tightly against an unloading guide rail vertical surface by a second mounting bracket to generate an unloading force.

Abstract: Methods of forming metal-containing films for electronic devices (e.g., logic devices and/or memory devices) and methods for reducing equivalent oxide thickness (EOT) penalty in electronic devices are disclosed. The methods comprise exposing a substrate surface to a metal precursor, such as titanium chloride (TiCl4), a reducing agent, such as a cyclic 1,4-diene, and a reactant, ammonia (NH3), either simultaneously, partially simultaneously or separately and sequentially to form the metal-containing film.

Abstract: The invention relates to the technical field of battery safety, and in particular to a safety monitoring method and system for a vehicle. The invention is intended to solve the problem that a battery cannot be continuously and safely monitored when a new energy vehicle is parked. To this end, the safety monitoring method in the invention includes: when a vehicle is in a parked state, waking up a battery management controller at specific time intervals, and obtaining status data of the battery by means of a battery management controller; determining, based on the status data, whether the battery is in an anomalous state; and when the battery is not in the anomalous state, controlling the battery management controller to enter hibernation state again; or when the battery is in the anomalous state, further waking up a wireless communications network, and uploading the status data and/or an alarm signal to a remote monitoring platform by means of the wireless communications network.
