The invention provides an efficient cooling and fresh-keeping device for lychee fruits, the efficient cooling and fresh-keeping device comprises a cooling box, a conveying mechanism, a draining platform and a transfer mechanism, the transfer mechanism comprises a rotating motor, a roller, a driving wheel, a rotating shaft, a driven wheel, an incomplete gear, a synchronous belt, a rack, a push plate and a spring, and the conveying mechanism conveys the lychee fruits into the cooling box for cooling and fresh keeping; litchi fruits can continuously float forwards in low-temperature water, the rotating roller can press the litchi fruits into the water, finally, the litchi fruits can float to the position between the push plate and the roller, and when the rotating motor drives the roller to rotate, the rotating shaft can be driven to rotate synchronously through the driving wheel, the synchronous belt and the driven wheel. The incomplete gear on the rotating shaft can be periodically meshed with the rack, the rack can drive the push plate to move, the push plate can push the lychee fruits to the side wall of the roller, the roller can drive the lychee fruits to a draining platform to be discharged when rotating, the lychee fruits are prevented from being damaged due to the fact that the lychee fruits are located in low-temperature water for a long time, and the cooling and fresh-keeping efficiency is improved.

The present disclosure provides a memory device that efficiently performs a compression operation and an operating method thereof, the memory device including: a memory device having a memory area; a compression operation unit that generates compressed data by performing a first compression operation on the write data; and a control operation unit that divides the storage area into a plurality of storage spaces, selects N selected storage spaces, controls the compression operation unit, and controls the compression operation unit when an operation rate of a first compression operation reaches a first operation rate at a first time, when the sum of the size of the first data and the size of the second data is equal to or smaller than a storage size corresponding to (N-K + 1) selected storage spaces, storing the first data and the second data in the (N-K + 1) selected storage spaces, the first data being a compressed portion in the data written at the first time, and the second data being a compressed portion in the data written at the second time; the second data is an uncompressed portion of the written data at the first time.

This invention discloses an optical path system and method for exposing a polarizing holographic grating, including but not limited to a light source module, a polarization, beam expansion, and collimation module, an interference exposure module, and an orientation module. These modules are arranged sequentially along the center line of the optical system. The light source module emits a light beam; the polarization, beam expansion, and collimation module changes the polarization direction of the emitted beam, filters and expands the beam, and collimates the beam; the interference exposure module exposes the beam through interference; and the orientation module adjusts the substrate position. This invention reduces the volume of the traditional polarizing holographic grating exposure optical path, simplifies the traditional polarizing holographic grating exposure method, reduces the difficulty of implementing the exposure optical path engineering, and improves the integration and stability of the polarization holographic exposure optical path.

This utility model discloses a cooking appliance, belonging to the technical field of household appliances, solving the problems of detachable pots being difficult to grasp and the resulting burns. It includes a pot body, an inner pot within the pot body, a steaming box assembly within the inner pot, and a lid within the pot body. The area inside the inner pot below the steaming box assembly is the cooking zone. The steaming box assembly includes a steaming box and a lid. The inner bottom wall of the steaming box is sealed, and the lid covers the steaming box. The steaming box has at least two independent cooking zones, and the steaming box has a handle for the user to remove and place it. This utility model mainly improves the ease of removing the cooking zones, increases the efficiency of user removal, and reduces the possibility of burns during removal.
