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 guide device for guiding a furniture part movable relative to a furniture body comprises: a guide unit including a body rail fixable to the furniture body; a sliding rail connectable to the movable furniture part and displaceably mounted relative to the body rail via a rail guide movable in a sliding direction, wherein the rail guide is mounted displaceably relative to the body rail and the one sliding rail and, when withdrawn to an open position, abuts against stops on the body rail and sliding rail; and a damper to damp the impact of the rail guide on at least one of the stops. The rail guide comprises at least two guide sections arranged behind one another in the sliding direction. The guide sections are connected to one another by a damping section that is flexible in the sliding direction and equipped with the damper.

A slide rail assembly includes a first rail, a second rail, an engagement element and an operating element. The first rail has a blocking feature. The second rail is movable relative to the first rail. The engagement element is arranged on the second rail. When the second rail is moved to a predetermined position relative to the first rail, the engagement element abuts against the blocking feature. The engagement element is configured to be moved away from the blocking feature of the first rail in response to operation of the operating element.

A domestic appliance device, in particular a domestic refrigeration appliance device, has an appliance body which defines at least one storage space, at least one insertion unit which is movable at least partially parallel to a direction of insertion into the storage space and parallel to a direction of extension out of the storage space, and at least one coupling unit which couples the insertion to the appliance body. The coupling unit has at least one roller rail and at least one roller element cooperating with the roller rail. In order to achieve greater ease of operation, the roller element is fastened to the appliance body.
