Abstract: This application relates to a tab flattening device. The tab flattening device includes: a roller configured to convey an electrode plate, a cover, and a flattening portion. The surface of the roller is in contact with the electrode plate in a contact region. The cover surrounds the contact region peripherally and includes a feed-in guide surface oriented toward the contact region. The flattening portion is disposed protrusively on the feed-in guide surface, and located opposite to a tab of the electrode plate. A tab guide surface is formed on the flattening portion. Along a feed-in direction of the electrode plate, the flattening portion is at least partially located upstream of the contact region.

Abstract: The three-state spintronic device includes: a bottom electrode, a magnetic tunnel junction and a top electrode from bottom to top. The magnetic tunnel junction includes: a spin-orbit coupling layer, a ferromagnetic free layer, a barrier tunneling layer, a ferromagnetic reference layer, three local magnetic domain wall pinning centers and domain wall nucleation centers. An antisymmetric exchange interaction is modulated, and the magnetic domain wall pinning centers are embedded in an interface between a heavy metal and the ferromagnetic free layer. The magnetic domain wall nucleation centers are at two ends of the ferromagnetic free layer. A current pulse flows through the spin-orbit coupling layer to generate a spin current and the spin current is injected into the ferromagnetic free layer. Under a control of all-electrical controlled, an effective field of a spin-orbit torque drives domain wall to move and displace.

Abstract: The present disclosure relates to a tobacco flavoring machine, comprising: a drum (1) capable of rotating about an axis thereof as a rotation center; a nozzle (6) disposed in the drum (1) to spray a liquid flavor to tobacco shreds in the drum (1); and a shoveling plate (5) arranged on an inner wall (11) of the drum (1) and extending from an inlet end of the drum (1) towards the interior of the drum (1), the shoveling plate (5) being disposed obliquely with respect to a generatrix (9) of the drum (1). The present disclosure improves the problem of the related art that tobacco shreds cannot flow smoothly from an inlet end toward an outlet end because a shoveling plate (5) is parallel to an axis of a drum (1).

Abstract: An adjustable shower head holder with a self-locking structure includes a holder body, a lifting rod, a locking assembly, and an operating member. The holder body is movably connected to the lifting rod through the locking component. The operating member is movably fitted to the locking assembly for switching a locked state and an unlocked state of the locking assembly. With a single operation of the operating member, the locked state and the unlocked state of the locking assembly can be changed, thereby positioning or moving the holder body. The operation is simpler. The use is safer.

Abstract: A wall-mounted shower head holding structure includes a suction cup assembly capable of holding a shower head. The suction cup assembly includes a suction cup body and a retractable mechanism. The suction cup body can be retractably held to a front end of a wall-mounted main body through the retractable mechanism. When in use, the shower head is attached to and held at the front end of the suction cup assembly. It is quite convenient for use, and does not affect the use of the shower head.

Abstract: A push-button switching shower head structure includes a shower head body, a water inlet seat, a button, a push rod, a push block, a return spring, a ratchet wheel, a water distribution disc, and an outlet disc.
