Container comprising a first element 2 and at least a second element 3 movable relative to the first element 2 between a closed position and an open position, and a drive device 5 for moving the second element 3, wherein at least one deformation measuring unit 6 is provided with a deformation sensor 11 on at least one of the elements 2, 3 for detecting a force exerted on one of the elements 2, 3 and wherein a control unit 12 is provided for receiving and evaluating a deformation signal transmitted by the deformation measuring unit 6 and is provided for actuating the drive device 5.

A refrigerator includes a cabinet defining a storage chamber, a door configured to open and close the storage chamber, a cooling device configured to cool the storage chamber, an elevation device configured to move a container in the storage chamber upward and downward, a locking device disposed at the elevation device and configured to, based on the elevation device being rotated about a front end of the elevation device in a folded state, lock the elevation device to the folded state and maintain the folded state, and a support plate that is disposed at the elevation device and includes a handle disposed at a rear portion of the support plate.

Examples of the present invention include tool storage units and methods for storing tools. In examples of the present invention, a tool storage unit comprises a moveable housing with a guide system for allowing movement of the moveable housing in at least one direction. In various examples, the moveable housing is engaged with a base unit and is moved relative to the base unit by a moving mechanism. The moving mechanism moves the moveable housing to provide access to and/or conceal, at least in part, the moveable housing.

An improved electric slide rail includes a motor driving device and two slide rail assemblies symmetrically arranged. Every slide rail assembly includes a slide rail (2, 28) and a fixed rail (31, 26), wherein the slide rail (2, 28) is slidably sleeved on the fixed rail (31, 26), a rack housing (1, 10) is sleeved on an outer side of the fixed rail (31, 26), a rack (13, 11) is provided on the rack housing (1, 10), a gear (4, 16) engaged with the rack (13, 11) is mounted on the slide rail (2, 28); the motor driving device is installed on the slide rail (2, 28) through a fixing device and is electrically connected with a controller. The improved electric slide rail further includes a clutch (18, 39, 46) which is electrically connected with the controller, wherein the clutch (18, 39, 46) is arranged at a side where an output shaft of a motor (17, 41, 44) of the motor driving device is provided, and is connected with the slide rail (2, 28) through a linkage structure. The improved electric slide rail has a simple structure, which not only achieves manual and automatic pushing and pulling of the drawer, but also achieves laborsaving manual pushing and pulling and convenient use of the drawer when the motor is powered off. Moreover, the improved electric slide rail is also able to increase the capacity of the drawer and is extended in the service life.

A wafer cassette includes a case, a plurality of wafer trays, and a plurality of transmission mechanisms. The wafer trays are disposed in the case. Each of the wafer trays includes a central opening, a first groove, and a second groove. The diameter of the second groove is greater than that of the first groove. A bottom surface of the second groove is higher than that of the first groove. The first and second grooves surround the central opening. Each of the transmission mechanisms is connected to the corresponding wafer tray to move the wafer tray between a pick-up position and a received position. Since the wafer tray has grooves with different diameters, the wafer tray is capable of receiving wafers with different sizes.

A cabinet for securely storing items includes a drawer enclosure, a drawer, a cover, an electric actuator, and a switch. The drawer is slidable at least partially into and out of the enclosure, and includes a compartment. The cover is designed to block access to the compartment of the drawer when the cover is in a first configuration, and to allow access to the compartment when the cover is in a second configuration. The electric actuator is designed to move the cover from the first configuration to the second configuration. The switch is connected to the electric actuator, and when activated the switch selectively shorts the electric actuator. Sliding the drawer relative to the enclosure activates the switch.
