Patent EP-0445555-A2 (EP)
Inventor: JURASCHECK STEFAN
IPC: F02D41/26
Filed: 1991-02-14
Abstract: Method for the regulation of the camshaft phasing, continuously variable according to RPM, in which it is proposed to derive the actual value for the camshaft phasing directly from a comparison of the crankshaft position with the camshaft position. The reference value for the camshaft phasing is read off as a digital signal from a phasing characteristic. The difference between the actual value and the reference value is fed to a digital control element, the control parameters of which are adapted as a function of the speed of rotation. The output signal of the control element is converted by a D/A converter into an analog control signal, which is fed to a mechanical control system for adjustment of the reference value of the phasing. By adapting the control parameters as a function of the speed of rotation, a desired transient response is maintained over the entire speed range. <IMAGE>

Abstract: An RF signal received by an antenna (1) is amplified in an amplifier circuit (3) and is then tuned in a tuned circuit (4) to pick up a signal having a certain frequency and a certain level. Then, the picked up signal is mixed with another signal to output an IF signal and the IF signal is detected to reproduce the desired broadcasting program. An AGC circuit (8,9) ensures high and low levels of the received signal to make the received signal to a certain level. Further, a damping circuit (2) capable of switching a damping amount by a sensitivity switching signal is arranged in the rear stage of the AGC circuit. Hence, intensity of a signal for performing a detection or the like can be exactly switched based of the sensitivity switching signal in an automatic broadcasting station selection.

Abstract: A high intensity discharge lamp system includes an AC supply (20) or a chamber (16) within which a plasma conductor (14) is created to generate light. In order to confine charged particles within the chamber (16) and to inhibit migration and loss thereof, a DC circuit (28) taps power from the AC supply (20) and produces a DC potential which is applied to relatively large-surface components in the vicinity of the plasma chamber (16). Properly polarized, the large-surface components, such as a reflector (18) and a conductive housing (41), refractor or door, produces electric fields which inhibit migration of the charged particles. The result is improved color and light output as well as increased lamp life.

Abstract: 2.1. It is known in the case of a commercially available magnetic tape apparatus with a head drum which can be driven by a motor to heat the head drum by means of a heating element in order to prevent condensate forming on the head drum. For this purpose, the heating element is arranged on the stationary lower part of the head drum by means of a metal clip. The object is to reduce the effort involved in protecting such head drums from the formation of condensate. 2.2. For the heating of the head drum (90), which forms a mechanical unit with the motor (M), the ohmic resistance of the winding wire of the motor phase windings (U, V, W) is used by feeding a heating current (direct current) to the latter in the operating modes of the apparatus characterised by the motor being at a standstill. The heat thereby generated is then passed on from the motor (M) to the head drum (90). 2.3. In particular, a head drum for a video recorder. <IMAGE>

Abstract: For adjusting grinding machines to the respective required distance between workpiece and tool, accessories are used with which the instantaneous distance can be determined as a function of the surface of workpiece and tool. The object of the invention is to simplify the control devices, accelerate the adjustment and prevent damage to the surface of workpiece or tool by means of the control procedure. A combination of sensor elements has been developed to this end, which act simultaneously on the workpiece and on the tool and which determine their relative position by way of a fixed distance between both positions of action. A sensor finger 8 assigned to the workpiece 2 is used as sensor tool 6 and is connected fixedly to a light barrier 9. This light barrier 9 scans the tool 1. To determine the zero point, the sensor tool 6 is displaced in the direction of the tool 1 by means of the workpiece feed, until the light barrier 9 indicates mutual contact. The present relative position is thus determined by way of the fixed distance between sensor finger 8 and light barrier 9. A fixed stop 14 can be provided on the workpiece holder in order to determine absolute dimensions. …<IMAGE>…

Abstract: In accordance with the invention, gallium-containing layers are grown by molecular beam processes using as an arsenic precursor a compound of the dialkylaminoarsenic family (DAAAS) such as tris-dimethylamino arsenic (DMAAs). In contrast to conventional arsenic sources, DAAAs act as carbon "getters". When DAAAs are used as an arsenic source, the DAAAs getter carbon impurities from the gallium source. Thus, for example, DAAAs can be used as an arsenic source in combination with TMG as a gallium source to selectively grow high purity or n-type layers of gallium arsenide at low temperatures below 600°C. In addition DMAAs has been found to be an excellent cleaning agent for gallium arsenide materials.

Abstract: In a semiconductor laser element which has a semiconductor block (2) including a first end surface (1), a second end surface (3) opposite to the first end surface, and a principal surface (5) contiguous to the first and the second end surfaces, the internal end surface (6) is defined by forming a groove (7) from the principal surface to be opposite to the second end surface and nearer to the second end surface than the first end surface. The internal end surface serves as a front laser beam emitting surface while the second end surface serves as a rear laser beam emitting surface. Thus, an optical resonator is provided between the internal and the second end surfaces. The internal end surface is spaced apart from the second end surface by a length of 150 µm which is different from a length of the semiconductor block. The short cavity length with highly reflective facets yields improved high temperature operation.
