  • Apparatus for positioning a furnace module in a horizontal diffusion furnace
    Patent number: 5530222
    Abstract: Performance of a high temperature diffusion furnace is enhanced by an improved multi-furnace module design. The furnace is constructed of materials suitable for clean room environments with an adjustable leveling frame assembly. A slide out assembly and heating element alignment mechanism of individual furnace tube modules with a heating element hoist mechanism allows for enhanced maintainability. Heat treatment performance is improved by a sealed heating element with individual furnace module cooling system. Improved thermocouple positioning and composition has also enhanced heat treatment process control and heating element maintainability.

  • High temperature diffusion furnace
    Patent number: 5095192
    Abstract: The furnace 70 includes a heating element 72 which is restrained from growth during operation of the furnace 70 by retaining spacers 84 which provide a yoke 88 around the individual coils 102 of the heating element 72 and which spacers 84 are interlocked with each other. A high alumina fiber insulation 180 is applied to insulate the heating element 72. This high alumina fiber insulation 180 has enhanced properties with respect to shrinkage and devitrification.
