A continuous mousetrap
PendingCN122536551AAchieve active closureAchieve directional transfer
This invention discloses a continuous mouse-trapping device, belonging to the field of animal trapping technology. The device includes a first housing, a lifting box, a sealing plate assembly, a lifting assembly, a pusher assembly, an active space, a second housing, and a controller. The first housing contains a lifting space with inlets at both ends. The lifting box is slidably disposed within the lifting space and has an internal cavity extending through both ends, having a first position communicating with the inlets and a second position where both ends are closed. The sealing plate assembly is located at the inlets to close them after a mouse enters the internal cavity. The lifting assembly drives the lifting box to move up and down. The pusher assembly is located on the lifting box to push the mouse out of the internal cavity. The active space is adjacent to the lifting space; when the lifting box is in the second position, the internal cavity communicates with the active space. The second housing is located above the first housing and contains a flip-up assembly and a collection cavity. This invention enables automated continuous mouse trapping, improving the success rate of mouse trapping.

Ferroelectric metal regulated artificial anti-ferromagnetic free layer spin orbit torque magnetic random access memory
A spin-orbit moment magnetic random access memory (MORAM) and method for controlling an artificial antiferromagnetic free layer with ferroelectric metal are disclosed. The MORAM comprises multiple memory cells, with the free magnetic layer being an artificial antiferromagnetic structure comprising a first magnetic layer, a non-magnetically coupled layer formed on the first magnetic layer, and a second magnetic layer formed on the non-magnetically coupled layer. The ferroelectric metal layer simultaneously possesses ferroelectric polarization characteristics and a spin-orbit coupling effect, generating a spin-orbit moment when an in-plane current is applied to drive the magnetic moment reversal of the free magnetic layer. Simultaneously, the magnetic coupling state of the artificial antiferromagnetic structure is controlled by the ferroelectric polarization electric field. The simultaneous presence of ferroelectric polarization and spin-orbit coupling characteristics in the ferroelectric metal layer enables both ferroelectric control and spin-orbit moment writing functions, thereby simplifying the device structure, reducing the write current density required for magnetic moment reversal, and lowering device power consumption.

Automatic overturning and visual detection device for magnetic shoe
ActiveCN224405811UImplement automatic detectionImprove detection efficiencyElectric machineryStructural engineering
The utility model relates to the technical field of magnetic shoe production detection, specifically relates to a kind of automatic overturning vision detection device of magnetic shoe.The automatic overturning vision detection device of magnetic shoe includes conveying mechanism, automatic overturning mechanism and front and rear two vision detection stations.The conveying belt of conveying mechanism is driven by motor uniform speed to convey magnetic shoe.In the guide channel of automatic overturning mechanism, the space guide edge line of twisted steel plate guides magnetic shoe to gradually overturn 180 °, and end end receives steel plate to make it slowly fall down to prevent damage.In vision detection station, photoelectric sensor triggers vision camera to take photograph, after camera judges defect, pneumatic sorting mechanism blows bad product to collection box by blowing nozzle.Working, magnetic shoe is first detected by first station, after passing, overturns, and is detected by second station again, realizes double-sided automatic detection, efficiently and protects magnetic shoe.
