In a turbocharger for an internal combustion engine of a motor vehicle, comprising a turbine housing having first and second spiral passages, each of which is connected to at least one exhaust gas line of an exhaust train of the internal combustion engine and a turbine wheel disposed within a rotor chamber of the turbine housing and connected to a compressor impeller via a drive shaft for rotation with the impeller, the exhaust gas of the internal combustion engine can be routed through the spiral passages for admission to the turbine wheel via the first and second spiral passages which have different wrap angles around the turbine wheel.

In one aspect, a voltage controlled oscillator is provided that includes circuitry comprising tunable coupled resonator networks, which are coupled to a terminal of a pair of three-terminal devices through a tuning voltage network which supports wide-band tunability. In another aspect, a wide-band tunable resonator is provided that is amenable to integration in the integrated circuit form.

A locking and separating structure for a front face plate of a drawer comprises a fixing device arranged on a side plate. The front face plate is connected with the fixing device through one or more connecting elements. The fixing device is provided with one or more locking and separating devices used for locking and separating the connecting elements. Each locking and separating device comprises a separating element, a finger-shaped element and a holding element. When installed, the connecting elements are automatically locked in the mode that the connecting elements and the finger-shaped elements with acting force are fastened; when the connecting elements are detached, a tool acts on the holding elements with acting force and drives the holding elements to move, the tool and / or the holding elements act on the separating elements, the finger-shaped elements are separated from the connecting elements through the separating elements, and separation is achieved; when the connecting elements are separated from the finger-shaped elements, the positions of the connecting elements basically remain unchanged; the holding elements begin to return to initial positions at least when the tool is separated from the separating elements and / or the holding elements and the connecting elements are separated from the locking and separating devices with certain distances.

A locking and separating structure used for a drawer front face plate comprises a fixing device arranged on a side plate. The front face plate is connected with the fixing device through one or more connecting elements. One or more locking and separating devices used for locking and separating the connecting elements are arranged on the fixing device. Each locking and separating device comprises a separating element, a finger-shaped element and a keeping element. Each connecting element and the corresponding finger-shaped element with acting force are buckled when the connecting element is installed, so that automatic locking is achieved. When the connecting elements are detached, tools act on the keeping elements with acting force and drive the keeping elements to move, the tools then act on the separating elements, the finger-shaped elements are disengaged from the connecting elements through the separating elements, and separation is achieved. When the connecting elements are disengaged from the finger-shaped elements, the positions of the connecting elements are basically kept unchanged; when the tools leave the separating elements and / or the keeping elements and the connecting elements are disengaged from the locking and separating devices by a certain distance, at least the keeping elements start to reset to the initial positions. The locking and separating structure is high in practicability.

A nebuliser for a fluid which has a conveying tube for conveying fluid and a method for producing a thick-walled capillary. The conveying tube or the capillary is of multipart and / or double-walled construction, and in particular, is made up of a number of parts, such as an inner tube and an outer tube. This construction allows the device to be manufactured more easily and cheaply, in particular, when the inner diameters are very small.

A method of manufacturing a recirculating ball nut for a ball screw drive, comprising a base body which includes at least one recirculating ball track, the method comprising the following manufacturing steps: manufacturing the base body by precision forging; and finishing the recirculating ball track by a cutting method subsequent to manufacturing the base body.

A locking and separating system for a furniture drawer front panel comprises a fixing device arranged on a side plate. The front panel is connected with the fixing device through two connecting elements. Two sets of locking and separating mechanisms for locking and separating the connecting elements are arranged on the fixing device. Each locking and separating mechanism is provided with a finger-shaped element and an unlocking element which is in transmission connection with the finger-shaped element, wherein the finger-shaped element and the corresponding connecting element are locked and separated through movement of the unlocking element. The two sets of locking and separating mechanisms are independently and vertically arranged and do not interfere with each other when the locking and separating mechanisms and the corresponding connecting elements are locked and separated in a matched mode. Unlocking components are arranged on the locking and separating mechanisms, and the unlocking components jointly act on the unlocking elements of the two sets of locking and separating mechanisms successively, so that the finger-shaped elements are disengaged from the connecting elements, and the front panel is separated from the side plate. According to the structural improvement, the locking and separating system has the advantages of being simple and reasonable in structure, reliable in performance, firm in connection, low in manufacturing cost, rapid and convenient to disassemble and assemble, high in flexibility and practicability, and the like.
