    摘要: A tool having an operating element that is driven by an integrated power drive for the percussive, pounding or vibratory loading of a material to be worked, in particular a tamper, a vibration plate or a vibration roll for ground compaction or a hammer for breaking and/or drilling operations, can be guided using a handle. This handle is actively vibration-damped by at least one actively controlled or regulated compensation element, which counteracts the transmission of a vibration to the handle and which, depending on the vibration that can be transmitted to it and is produced in and/or on the tool, produces a compensating force and/or movement in the potential vibration transmission path from the location of production of the vibration to the handle.

    摘要: The inventive percussion and/or drill hammer (10) consists essentially of a hammer housing (12) which surrounds a rotor for a percussive tool (11), including the drive mechanism and the holding element, and an outer shell (14) which encompasses the hammer housing (12) at a distance. Said outer shell (14) is connected elastically to the hammer housing (12) at selected coupling points and is connected to a first handle (16) at the end facing away from percussive tool (11) in the direction of impact of said percussive tool (11). The outer shell (14) extends as far as or at least almost as far as the percussive tool (11) where it is provided or can be provided with a second handle (17), said percussive tool projecting out of the hammer housing (12).

    摘要: A percussion drill and/or jack hammer has a handle that is spring-buffered against the hammer housing which has at least one straight guiding track running parallel to the longitudinal axis of the hammer. The handle can be moved to a limited extent along the guiding track in relation to the hammer housing and is spring-buffered in such a way that its movement against the guiding track is limited on all sides.

    摘要: A method of forming a semiconductor device includes forming an opening having a sidewall in a substrate and forming a first epitaxial layer in the opening. The first epitaxial layer is formed in a first portion of the sidewall without growing in a second portion of the sidewall. A second epitaxial layer is formed in the opening after forming the first epitaxial layer. The second epitaxial layer is formed in the second portion of the sidewall. The first epitaxial layer is removed after forming the second epitaxial layer.

    摘要: A method of manufacturing a semiconductor device is disclosed. The method includes forming a first conductive layer over a substrate. The first conductive layer has a top surface and sidewalls, wherein the first conductive layer comprises an overhang of a non-conductive material along the sidewalls. The method further includes forming an insulating layer on the first conductive layer, and forming a sacrificial layer over the insulating layer and the overhang of the first conductive layer. The sacrificial layer is partially removed wherein a residue of the sacrificial layer remains beneath the overhang, and a second conductive layer is formed on the insulating layer.

    摘要: A percussion mechanism that has a motor, a drive piston which can be moved to and fro in a guide cylinder by the motor, and a percussion piston. A coupling device is active between the drive piston and the percussion piston, via which coupling device the movement of the drive piston is transmitted to the percussion piston. The motor can be configured as a reluctance motor or as a synchronous motor. The motor can be actuable in such a way that different rotational speeds of the rotor can be generated within a percussion cycle and/or from percussion cycle to percussion cycle.

    摘要: A percussion tool has a cooling air channel for guiding a cooling air flow from a cooling air fan to an outside wall of a cylinder of an internal combustion engine. The cooling air channel is tapered to the extent that partial cooling air flows guided between the respective cooling fins are branched off the main cooling air flow. In such a way, the flow rate of the cooling air flow in the cooling air channel remains substantially constant, resulting in optimized engine cooling. The cooling air channel may be divided into two cooling air channels downstream of the cylinder. One of the cooling air channels guides cooling air to an exhaust gas system of the internal combustion engine, while the other cooling air channel guides cooling air to an outside wall of the guide housing of a hammer mechanism.

    摘要: A drilling and/or percussive hammer comprises a handle and a hammer housing, which can move relative to the handle and inside of which, among other things, a pneumatic spring percussive mechanism is housed. The pneumatic spring of the pneumatic spring percussive mechanism can be ventilated via a no-load operation duct that is opened and closed by a valve. The valve can be opened and closed according to a pressing force acting upon the handle. A delay device controls the valve during closing so that the valve reaches the position corresponding to the detected pressing force only with a time delay. This causes a smooth transition from the no-load operation to the percussive operation.
