  • Patent number: 7667162
    Abstract: During fabrication, a rotating semiconductor substrate is radiated in accordance with a thermal recipe. Temperature measurements of the semiconductor substrate are obtained along with the position of the semiconductor substrate at the time of each temperature measurement. It is then determined for the position of the semiconductor substrate whether at least one particular temperature measurement of the temperature measurements should be filtered. If so, at least one filtered temperature measurement is obtained. The radiation of the semiconductor substrate is subsequently controlled based on the temperature measurements, the at least one filtered temperature measurement, and the thermal recipe.

  • Patent number: 7358464
    Abstract: A method for temperature measurement in a household appliance includes generating a high-frequency electromagnetic excitation wave of a predefined transmit frequency. The transmit frequency is selected from a frequency band including temperature-dependent resonant frequencies that occur in a surface wave device incorporated in a temperature measuring probe and which respectively correspond to temperatures expected at the temperature measuring probe during operation of the household appliance. During a first phase, the excitation wave is wirelessly transmitting to the surface wave device. During a second phase following the first phase, an electromagnetic response wave generated by the excitation wave in the surface wave device is wirelessly transmitting to a processing unit.

Arranged in the housing (110) is a radial fan wheel (130) that serves to generate a flow from the air inlet (116) via the pressure chamber (115) to the air exit opening (118). Also provided is an electrical heating element, e.g. a PTC (Positive Temperature Coefficient) heating element (125), that serves to transfer heat to the air flow generated by the fan. Air-directing elements (632, 634, 636, 638) are provided between the exit opening (118) and the heating element (125), in order to generate an air flow having a more uniform (680) velocity distribution.

  • Patent number: 7332693
    Abstract: Functional elements, particularly PTC heating elements, are braced in a hollow reception means, such as a profile tube. The reception means have two at least partly concave top wall areas facing one anther and flat sides of the functional elements and in this way permits a bracing of the functional elements, in that side walls of the reception means, extending substantially perpendicular to the concave top wall areas, are subject to the action of a pressing pressure. In the free space areas defined by the concave top walls can be fitted ends of attachment parts, such as metal lamellas, which are clamped in the same operation, according to the invention, during the bracing of the functional elements. This makes it possible in a simple manner to manufacture assembled devices, particularly electric heating devices.
