A drawer apparatus capable of locking and unlocking a drawer without position control and motor stop control is provided. A lock frame is released from the hook to be brought into an operable state by unidirectional rotation of a DC motor in an engaged state. A drawer is released from an anchor to be advanced out of the retracted position when the lock frame operates. A planetary gear unit is pushed by the lock frame. A small-diameter planetary gear is thereby shifted from the engaged state to a default state. The anchor is engaged with the drawer when the advanced drawer is pushed back to the retracted position. The hook is engaged with a lock when the advanced drawer is pushed back to the retracted position.

A furniture drive for retracting a movably supported furniture part into a closed position relative to a furniture carcass includes a housing, an entrainment member which can be releasably coupled to the movable furniture part, a spring device for applying a force to the entrainment member, and a guide path arranged or formed on the housing. The entrainment member is displaceably arranged along the guide path, and the guide path includes a first bend for releasably locking the entrainment member. The guide path includes at least one second bend for releasably locking the entrainment member, and at least one movably-supported switch element with a first and with a second switching position is provided. The switch element, in the first switching position, blocks the first bend so that the entrainment member can move into the second bend and the switch element, in the second switching position, unblocks the first bend so that the entrainment member can move into the first bend.

A mounting assembly is provided for supporting card readers in an electronic equipment rack, where the rack is configured to house therein the card readers and electronic equipment in communication with the card readers. The mounting assembly generally includes a bracket configured to couple to a frame of the rack, and at least one mount configured to couple to a card reader. The at least one mount is further configured to releasably couple to the bracket while the bracket is coupled to the frame of the rack to thereby position the card reader, when coupled to the at least one mount, in the rack. What's more, the bracket may be free of arms extending away from the bracket when the at least one mount is uncoupled from the bracket.

The refrigerator includes a cabinet having a storage compartment, a door hingedly connected to the cabinet for opening and closing the storage compartment, a drawer provided in the storage compartment, a sensor for sensing whether the door is open, an electric driving unit including a moving frame, the electric driving unit being configured to move the drawer to a manipulating position spaced apart forward from an initial position by a predetermined distance through forward movement of the moving frame when it is sensed that the door is open, and a rail configured to allow the drawer to move forward and rearward relative to the storage compartment, wherein the electric driving unit is driven to return the moving frame to the initial position after the moving frame is moved to the manipulating position.

A guide device which is producible in a simple manner and which enables reliable and stable guidance of two elements moveable relative to each other, the guide device comprises a guide rail and a sliding body which is displaceable in sliding manner on the guide rail along a guide direction, Wherein the sliding body comprises at least one pair of mutually oppositely located sliding surfaces with which the sliding body rests on at least one pair of mutually oppositely located contact surfaces of the guide rail, wherein the sliding body comprises a pressing device with the at least one pair of sliding surfaces of the sliding body is pressable onto the at least one pair of contact surfaces of the guide rail.

An object of the present invention is to provide a synchronic drawer slider rail system with a mute springback function, which can solve conventional problems of a large occupation rate and a low carrying capacity due to a damping device of a springback mechanism of a drawer slider rail system is placed at a bottom end inside a slide rail. The synchronic drawer slide rail system with a mute springback function includes: two slide rail units, wherein two external faces of a drawer are connected to two internal faces of a cabinet in a relative sliding form through the slide rail units which are symmetrically arranged; the two slide rail units are synchronically connected to each other through a synchronizing mechanism; wherein a shell unit is fixed on each of the two internal faces of the cabinet; a linear groove extending along a relative sliding direction of the drawer and the cabinet is provided on a side face, which faces the drawer, of the shell unit; each of the slide rail units is installed in the linear groove; a horizontal board extending towards the drawer is arranged at a bottom face of the shell unit, and a rack is provided on an inner end of the horizontal board; a down-facing groove is formed between a bottom groove wall of the linear groove and the rack, and a slide rail springback mechanism is installed in the down-facing groove.

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.
