Abstract: The invention discloses a detachable and easily cleanable meat tenderizer, which includes a housing, a blade holder, a blade and a baffle plate. The housing is provided with a chamber that is sized to fit the blade holder. The housing is internally provided with a clamping-type locking device which includes a clamping-type locking body and a return spring. The clamping-type locking body is provided with a clamping groove at a lower end thereof, a return post at the rear thereof and a control button in the front thereof. A clamping portion adapted to the clamping groove is arranged at an upper part of the blade holder, and the blade holder is connected to the housing when the clamping portion is clamped into the clamping groove. Limiting cavities are arranged on both sides of the housing. Guide posts are arranged on both sides of the blade, one end of the guide post is located in the limiting cavity of the housing, and the other end of the guide post is detachably connected to the baffle plate.

Abstract: The invention discloses a detachable and easily cleanable meat tenderizer, which includes a housing, a blade holder, a blade and a baffle plate. The blade is mounted in the blade holder. The housing is internally provided with a chamber that is sized to fit the blade holder, and the chamber is internally provided with a pushing-type locking device. The pushing-type locking device includes a pushing block and a sliding groove fixedly connected on an inner wall of the chamber for pushing the pushing block to slide. The blade holder is provided with a fixing groove that is sized to fit the pushing block. The housing is connected to the blade holder when the pushing block is pushed into the fixing groove, and the housing is disengaged from the blade holder when the pushing block is pushed away from the fixing groove.

Abstract: The disclosure relates to a hybrid aqueous rechargeable battery, wherein the battery comprises a positive electrode and a negative electrode, and wherein the positive electrode and the negative electrode are in aqueous electrolytes with different pHs respectively. The hybrid aqueous rechargeable battery has a working voltage at least 0.6 V higher than the conventional aqueous lithium batteries and a theoretical energy density at least 60 Wh/kg higher. The hybrid aqueous rechargeable battery can be used for storage and discharge of electricity, etc.

Abstract: A method of detecting contact between a transducing head-carrying slider and a rotatable disc is performed by applying an electrostatic voltage between the slider and the disc and monitoring current flow across an interface between the slider and the disc. The monitored current flow across the interface between the slider and the disc is analyzed to detect contact between the slider and the disc.
