  • Patent number: 12178212
    Abstract: An expansion compensating coupler comprised of at least two expansion compensating assemblies for mounting a platen to a dough press. One end of a threaded rod is perpendicularly attached to the platen. A nut is turned onto the rod, a washer is placed on the rod, the rod is inserted through the bore of a sleeve residing in a hole in the dough press, a washer is placed on the rod, and a nut is turned onto the rod. The nuts are tightened to secure the platen to the dough press. The sleeve bore has the same diameter as the rod and the outer diameter of the sleeve is smaller than the hole so that there is a gap. Heating the platen causes it to expand and the threaded rod/sleeve to move into the gap. The minimum gap size is the maximum amount of expected expansion of the platen.

    Abstract: A resistive heating element 30 has a higher molybdenum carbide content in a central portion 35 than in a peripheral portion 34. Since molybdenum carbides have a low temperature coefficient of resistance compared to molybdenum, the amount of heat generated in the central portion 35 of the resistive heating element 30 does not increase as much as in the peripheral portion 34 even when the temperature is increased, and the increase in difference in temperature between the peripheral portion 34 and the central portion 35 can be suppressed. In other words, generation of hot spots near the center can be suppressed and a good uniform heating property in a wide range of operation temperatures can be obtained.

In one aspect, a system is described for processing a treatment object having a given emission spectrum at a treatment object temperature which causes the treatment object to produce a treatment object radiated energy. The chamber responds in a first way to the heating arrangement radiated energy and in a second way to the treatment object radiated energy that is incident thereon. The chamber may respond in the first way by reflecting the majority of the heat source radiated energy and in the second way by absorbing the majority of the treatment object radiated energy. Different portions of the chamber may be treated with selectively reflectivity based on design considerations to achieve objectives with respect to a particular chamber performance parameter.

  • Patent number: 6723964
    Abstract: A heating and cooling apparatus is provided which employs a series of thermally conductive plates thermally coupled to heating and cooling devices to heat or cool a mounting plate loaded with semiconductor devices. The mounting plate is assembled on a heating plate, which is then assembled on a cooling plate. The heating plate includes upper and lower plates with a heater therebetween which can heat the heating plate to a desired temperature, which in turn heats the mounting plate and the semiconductor devices. The cooling plate has ‘S’ shaped flow grooves formed throughout. When cooling fluid is flowed through the flow grooves, the cooling plate is cooled, which cools the heating plate, which in turn cools the mounting plate and the semiconductor devices.

  • Patent number: 6518551
    Abstract: A heating apparatus includes a heater 6 which includes a first heating conductor pattern 1, a second heating conductor patterns 2 and an elongated plate-shaped member 3 made of heat-resistive and insulated material. The first heating conductor pattern 1 is disposed in the central portion in a longitudinal direction of the plate-shaped member 3. The second heating conductor patterns are disposed in both end portions of the plate-shaped member in the longitudinal direction. The first heating conductor pattern 1 and the second heating conductor patterns 2 are independently controlled their temperature. Current is first fed to the first heating conductor pattern 1, and the current feeding is stopped, and current is then fed to the second heating conductor patterns 2. Accordingly, the protective member placed on and along the heater 6 is gradually heated from the center to both ends.
