  • Publication number: 20020139410
    Abstract: A radiation sensor which includes a thermopile for detecting radiant energy. The thermopile and a support rim for the thermopile are fabricated as an integrated unit to form a support chip. The support chip is mated to a mating chip so that the thermopile is positioned in an inner cavity region of the radiation sensor. The sensor has a window which permits the transmission of radiant energy into the enclosure such that the radiant energy impinges upon a central absorber region of the thermopile.

  • Publication number: 20020021743
    Abstract: The invention provides a temperature sensor on the basis of a thermocouple constituted by two different metals. The first metal is provided in the form of an electrically insulated wire, having a blank uninsulated portion. The second metal is constituted by a jacket member enclosing the insulated wire. The jacket member is in electrical contact with the insulated wire via the blank uninsulated portion to thereby form a measuring junction. As a feed line, an electrically insulated copper wire is provided whose free end has a blank portion. The first wire is wound around the copper wire and projects over the free end thereof. The jacket member extends over the blank uninsulated portion of the carrier wire and is in electrical contact therewith. Due to the fact that the same material is chosen for the jacket member and for the carrier wire, i.e. copper, the carrier wire can be used as electrical feed line.

  • Patent number: 6325858
    Abstract: A generally horizontally-oriented quartz CVD chamber is disclosed with front and rear chamber divider plates adjacent a centrally positioned susceptor and surrounding temperature control ring which divide the chamber into upper and lower regions. Improvement to the lifetime of CVD process components and related throughput improvements are disclosed. A getter plate for attracting some of the unused reactant gas is positioned downstream from the susceptor extending generally parallel to and spaced between the divider plate and the upper chamber wall. This getter plate also minimizes deposition on the chamber walls and improves the efficiency of a cleaning step. Reradiating elements are also located adjacent side walls of the chamber to heat cooler chamber wall areas. The getter plate and the reradiating elements plus the susceptor and surrounding ring are all made of solid chemical vapor deposited SiC to improve the life of the chamber.

  • Patent number: 6299348
    Abstract: An immersion measuring probe for measurement in liquids, in particular in molten metals, has a carrier tube, a measuring head mounted on one end of the carrier tube, and measuring elements as well as signal lines for the measuring signals generated by the measuring elements arranged on the measuring head. The signal lines are longer than the carrier tube and run from the end of the measuring head facing the inside of the carrier tube. In order to improve the handling of the immersion measuring probe, the signal lines are guided through the inside of the carrier tube and are wound up there around its longitudinal axis.

  • Patent number: 5939667
    Abstract: A subsea thermoelectric generator has a plurality of flat thermoelectric modules attached concentrically to the outside wall of an undersea line in which petroleum products extracted from a subsea drilling well circulate. The thermoelectric modules are disposed in flat-bottomed pans machined into the outside wall of the line. The pans are sealed by lids made of heat-conducting material and in thermal contact with the thermoelectric modules. Each lid defines, with the walls of the corresponding pan, a peripheral sealed chamber. The various chambers in the pans communicate with each other through passages provided in partitions that separate the pans and are filled with a soft (compliant), preferably non-heat-conducting, resin. At least one of the pans is provided with an orifice closed by a sealed deformable element.
