Abstract: The present invention provides a novel high-efficiency infrared ray heating apparatus enabling concentrated heating of infrared rays to achieve high efficiency and seeking to reduce the size and weight to be usable on a desk, thereby achieving power saving. An infrared condensing side rotation reflector is connected to an infrared emission side rotation elliptic reflector. An infrared ray lamp is arranged in a focal position of the infrared emission side rotation elliptic reflector. The infrared emission side rotation elliptic reflector and the infrared condensing side rotation reflector are configured in such a shape that infrared rays reflected by the infrared emission side rotation elliptic reflector and the infrared condensing side rotation reflector are condensed with concentration on a tip small-diameter portion of the infrared condensing side rotation reflector. In some embodiments, a quartz rod focuses this infrared energy from the loop onto a specimen mounting stand.

Abstract: Thermal treatment equipment for rapidly heating a SiC substrate having a diameter of several inches or larger to a temperature as high as 1200° C. or higher with a high in-plane evenness by heating a peripheral zone of a substrate using high frequency induction and by heating a central zone of the substrate using infrared lamps while the substrate and a stage thereof are covered with a shield plate.

Abstract: A control method of a gas turbine provided with a plurality of combustors each of which has a first stage combustion part effecting diffusion combustion and a second stage combustion part effecting premixed combustion, comprises: monitoring a quantity of state representative of the combustion condition of the combustor or gas turbine, and regarding the combustion condition as being abnormal combustion when the quantity of state exceeds an allowable value and lowering gas turbine load to a predetermined partial load, thereby to continue the operation.

Abstract: A control method of a gas turbine which is provided with a multi can type combustor consisting of a plurality of unit combustors, each of which has a first stage combustion section for diffusion combustion and a second stage combustion section for premix combustion. Combustion states in the first and second stage combustion sections are monitored to take in quantities representative of the combustion conditions as control factors. The combustion in the second stage combustion section is assumed to be abnormal when the taken in quantities exceed an allowable limit and the combustion in the first and second stage combustion sections is changed to independent combustion only in the first stage combustion section when the number of unit combustors, each of which is assumed to be abnormal, exceeds a predetermined number of the unit combustors.
