摘要:
A percussion mechanism (21; 41) for a percussion power tool includes an impact element (24; 44) reciprocating along a percussion axis (22; 42) of the percussion mechanism (21; 41) and acting on the striker (26, 46). The contact point (27, 47) and counter-contact point (28, 48) are provided between the striker (26, 46) and the impact element (24, 44), with the contact point (27, 47) being formed as an exposed contact point and being arranged outside of the percussion axis (22; 42).
摘要:
A power-branched transmission, particularly for agricultural vehicles such as tractors or similar, includes a stepped planetary gear which is disposed between an input shaft and an output shaft and is used for dividing the power supplied at the input shaft onto a mechanical power branch and a hydraulic power branch. The hydraulic power branch is formed by two hydraulically interconnected, identical hydrostatic axial piston engines which can be selectively operated as a pump or an engine, can be swiveled within a predefined pivoting angle, and can be connected to the input shaft or the stepped planetary gear in a different manner via two respective clutches so as to cover different operating ranges or running steps. In order to obtain better efficiency in such a power-branched transmission, the two hydrostatic axial piston engines are configured as wide-angle hydrostats that are provided with a minimum pivoting angle range of 45°.
摘要:
Method of producing a vertically inhomogeneous platinum or gold distribution in a semiconductor substrate with a first and a second surface opposite the first surface, with diffusing (100) platinum or gold into the semiconductor substrate from one of the first and second surfaces of the semiconductor substrate, removing (102) platinum- or gold-comprising residues remaining on the one of the first and second surfaces after diffusing the platinum or gold, forming (104) a phosphorus- or boron-doped surface barrier layer on the first or second surface, and heating (105) the semiconductor substrate for local gettering of the platinum or gold by the phosphorus- or boron-doped surface barrier layer.
摘要:
A method shuts down and switches on cylinders in a motor vehicle internal-combustion engine. Injection valves are controlled by an engine timing system as a function of vehicle operating conditions. The shutting-down of cylinders is carried out sequentially according to a defined program. Vehicle brakes can be acted upon in a power-operated manner. In order to prevent a switching jolt when shut-down cylinders are switched on again, when the cylinders are switched on again, the running up of the engine takes place in steps according to another defined program and a braking intervention is carried out.
摘要:
Halogen bulb without additional safety device for high-volt/intermediate-t operation with a bulb pinched on one side produces an inherent safety effect by producing a current lead segment that is pinched from an uncoiled wire with a diameter of 130 .mu.m at most and the distance between the two current leads is suitably selected.

Techniques related to implementing neural networks for speech recognition systems are discussed. Such techniques may include implementing frame skipping with approximated skip frames and/or distances on demand such that only those outputs needed by a speech decoder are provided via the neural network or approximation techniques.

Connection data, for example, a telephone number, and a corresponding identification, for example, the name of the telephone subscriber associated with the corresponding telephone number, is automatically extracted from a data memory and saved in a dialing directory memory.
摘要:
In a flexible disk (10) made of rubber-elastic material and having a central axis (A) at least two first and two second connection bodies (32, 34) are inserted alternately, with their own axis (B) parallel to the central axis (A), around the axis (A), at angular distances from one another; they are intended to be fastened each to one of the shaft ends. Flexible inserts (20) are moreover embedded in the flexible disk (10) and extend around adjacent connection bodies (32, 34). For effecting the mutual centring of the two shaft ends a centring device (40) is provided, which comprises a first and a second end plate (22, 24), which are arranged centred in relation to one another each against one end face (12, 14) of the flexible disk (10) and are pivotable about a joint centre (C) lying on the central axis (A). Independently of their subsequent fastening to the first and/or second shaft end the first connection bodies (32) are fastened to the first end plate (22)and the second connection bodies (34) to the second end plate (24) rigidly and securely against rotation.
摘要:
Commercially available voice recognition systems are generally speaker-dependent, with the voice recognition system first being trained to the voice of the speaker before it can be used. A disadvantage with this method is that modified reference data has to be buffered and permanently saved in several steps when the speaker adaptation algorithm is executed, and thus requires a lot of memory space. This primarily negatively affects applications on devices with restricted processor power and limited memory space, such as mobile radio terminals for example. A method of speaker adaptation for a Hidden Markov Model based voice recognition system may address these issues. In the method, the memory space requirement and thus also the processor power required can be considerably reduced. This is achieved by using modified reference data in a speaker adaptation algorithm to adapt a new speaker to a reference speaker. The modified reference data is processed in compressed form.
摘要:
A working tool for use with a percussion power tool and including a cushioning elongate stem (3), and a head (4) connected with the stem (3) for joint rotation therewith and for a limited axial displacement relative thereto, with the tool head (4) being adapted, with respect to its resistance associated with its cushioning properties, to characteristics of the percussion piston (5) of the power tool and with the tool stem (3) and the tool head (4) having mutually abutting each other end surfaces (10) which form at least a partially flat contact upon abutting each other.
