Each vane includes a vane root (7), an outlet-side vane root end surface (9) and an inlet-side vane root end surface (8). The vane root (7) is at the inlet side (3) of the disk element (2) for mounting in its respective slot (5). A first bearing plate (12) is provided on the outlet side (4) of the disk element. At least one pressure piece shim (13) is provided in the slot (5). A second bearing plate (14) is provided on the inlet side (3). The disk element (2) is connected to the second bearing plate (14) by a radial connecting element (16) that is pressed to act on the shim in the slot to urge the root of the vane base (7) in the slot (5) to an outermost radial position. Further a method for producing a vane using such a blade wheel is disclosed.

Abstract: The regulated output voltage of a voltage regulator is maintained up to a current limit, Ilimit, then as the load impedance continues to decrease the output current does not increase past the current limit, Ilimit, but rather the output voltage decreases forcing the output current to also decrease to satisfy Ohm's Law: IOUT=VOUT/ZLoad. When the output voltage drops below the regulated voltage value because of current limiting the voltage regulator shifts from a current limit mode to a current foldback mode wherein the output current decreases with the decrease in output voltage until the output current reaches a current foldback minimum, Ifoldback, at an output voltage of substantially zero volts. As the load impedance increases so will the output voltage and current until the output voltage is back at substantially the regulation voltage value, and the output current is less than or equal to the current limit, Ilimit.

Abstract: An imaging includes an image acquisition module which has an image sensor and a first lens system, having a focal plane, for imaging an object onto the image sensor, a display module which displays the image captured by means of the image acquisition module such that a user can perceive it with one eye, and a control unit. A measuring module is provided to the control unit for measuring the accommodation state (B1(t)) of the eye of the user. The control unit adjusts the position of the focal plane of the first lens system on the basis of the measured accommodation state (B1(t)) and, at the same time, adjusts displaying of the image by means of the display module on the basis of the measured accommodation state (B1(t)) such that the user can perceive the displayed image in sharp definition with his eye having the measured accommodation state (B1(t)).

Abstract: A differential input operational amplifier has a voltage clamp differential transistor pair coupled to an input differential transistor pair of the operational amplifier. The voltage clamp differential transistor pair limits the output voltage of the operational amplifier by taking over control of the operational amplifier circuits from the input differential transistor pair as the output voltage approaches a clamp voltage value. A reference voltage may be used to set the output voltage at which the input differential transistor pair will be clamped by the voltage clamp differential transistor pair. Below the clamp voltage, operation of the input differential transistor pair will not be affected. At the clamp voltage the input differential transistor pair will no longer control the output of the differential amplifier, rather the voltage clamp differential transistor pair will control the maximum voltage output of the differential amplifier.

Two precision tooled adaptor bodies, preferably of cylindrical shape, are removably mountable in the indentations, where appropriate, for a given measuring task. The adaptor bodies are held in place by, e.g., magnets. The device is capable of determining the spatial orientation of rolls, bars, hollow or solid cylinders, ranging from small to large diameters by appropriately selecting in which of the grooves or indentations the adaptor bodies are mounted.
