Abstract: A latch assembly for securing two boards together includes a male section and a female section. The male section includes a base to be fixed to one board, a tab protruding from a first side surface of the base. The tab includes at least one latching portion protruding therefrom. The female section includes a support block fixed to the other one board and defining a chamber, a movable block slidably retained within the chamber of the support block, and the at least one elastic member is retained within the chamber. The movable block includes a stop portion capable of latching with the at least one latching portion when the movable block is retained in a securing position by the tab. The at least one elastic member applies a push force to the movable block to movably retain the movable block in the normal position.

Abstract: The present invention relates to a novel compound, 3-amino-2-hydroxy-4-phenylbutanoyl-valyl-isoleucine with structure showed below. The compound is prepared from fermentation culture Streptomyces parvus CGMCC No. 4027 and is active as inhibitor of aminopeptidase. It can be used for preparation of aminopeptidase inhibitor.

Abstract: A manipulator includes a main body, and a grasping device mounted to the main body. The grasping device includes a mounting board and two grasping members secured on the mounting board. The two grasping members move towards and away from each other, each grasping member is able to grasp a loader at a specific position of the loader.

Abstract: A cart includes a frame body, a tray, a driving mechanism, and a transmission mechanism. The frame body includes a top portion, a bottom portion including a number of castors, and a number of connecting bars between the top portion and the bottom portion, which cooperatively defines a receiving space. The tray is configured to support a workpiece and to be slidably received in the receiving space. The transmission mechanism is connected between the tray and the driving mechanism to transmit the power of the driving mechanism to the tray to drive the tray to move in the receiving space.
