摘要:
A luminescence diode (1) having an active zone (7) which emits electromagnetic radiation in a main radiating direction (15). A reflection-reducing layer sequence (16) is arranged downstream of the active zone (7) in the main radiating direction (15). The reflection-reducing layer sequence includes a DBR mirror (13), which is formed by at least one layer pair (11, 12), an antireflective layer (9) downstream of the DBR mirror (13) in the main radiating direction (15) and an intermediate layer (14) arranged between the DBR mirror (13) and the antireflective layer (9).

The invention relates to a percussion hammer and/or a drill hammer comprising a hammer housing, a handle which is preferably embodied as a handle cover and which can be displaced in a working direction (A) in relation to the hammer housing and which surrounds at least one part of the hammer housing. The hammer also comprises a guiding device which is used to guide the handle cover in a linear manner in relation to the hammer housing. The hammer is characterized in that the guiding device comprises a rolling body device which is active between the hammer housing and the handle cover. The rolling body device ensures that the handle cover is guided in a stable manner, with respect to tilting, in relation to the hammer housing.

The invention relates to a firearm (10), in particular a single or multi-shot repeating rifle comprising a stock (11), a barrel (30) axially displaceable relative to the stock (11) and resting on or in a linear guide (20), a cartridge chamber to receive a cartridge being constituted in said barrel, further a breech (40) fitted with a breech cap (41) to seal the cartridge chamber and axially affixable in the barrel end (32) when the firearm (10) is closed, and further a locking unit (80) to lock the firearm into the closed position. The linear guide (20) comprises at least one guide rod (21), guide fork or the like linked or linkable to the barrel (30) and guided in sliding manner within the stock (11). This design leads to a compact and easily manufactured firearm with a slender and attractive appearance. The firearm (10) furthermore is made of fewer parts, resulting in simple disassembly and small shipping size.

A device for a drilling hammer and/or percussive hammer has a tool holding fixture for holding a tool and for transmitting a torque to the tool. A component of the tool holding fixture consists of a hollow cylindrical tool holder, which has an insertion opening for an insertion end of the tool, and has an impact opening, via which a percussive action can be applied to the insertion end. A stopping surface, which is stationary with regard to the tool holder and which acts in an axial direction of the tool holder, is provided in the tool holder in the area of the impact opening. The tool holding fixture is particularly suited for insertion ends according to the SDS-max standard.

The invention concerns a pressure control valve for the control of the value of pressure in a hydraulic circuit, especially in a hydraulic circuit of a vehicle transmission, with a valve housing, with a solenoid coil, with an armature component group comprising an armature rod, an armature and advantageously, a spring, with a yoke and with a push rod, which is interposed between the armature rod and a control element, whereby the section of the valve housing (3) in the zone of the control element (16) consists of a plastic flange (2a), and further, the armature rod (1) possesses a control boring in the longitudinal direction, in which a pin (12, 12′, 12″) is inserted, the material and dimensioning are so selected, that the pin can compensate for a temperature based longitudinal change of the plastic flange (2a).
摘要:
A semiconductor component having a light-emitting semiconductor layer or a light-emitting semiconductor element, two contact locations and a vertically or horizontally patterned carrier substrate, and a method for producing a semiconductor component are disclosed for the purpose of reducing or compensating for the thermal stresses in the component. The thermal stresses arise as a result of temperature changes during processing and during operation and on account of the different expansion coefficients of the semiconductor and carrier substrate. The carrier substrate is patterned in such a way that the thermal stresses are reduced or compensated for sufficiently to ensure that the component does not fail.

The invention relates to a hand-held working tool, comprising a first unit, powered by a vibration on operation and a second unit which may be displaced relative to the first unit. A vibration isolation device is arranged between the first and second unit, comprising an actuator, for generation of a control force, by means of which the operational force acting in the working direction (A) between the first and the second unit may be at least partly compensated. The actuator is pneumatically operated and comprises an air spring for vibration isolation. A working piston in an air spring percussion device on the working tool serves to supply compressed air for the air spring. Alternatively, the compressed air can be supplied by the oscillating relative movement between the first unit and the second unit.
