Described herein is a fuel processor that produces hydrogen from a fuel source. The fuel processor comprises a reformer and burner. The reformer includes a catalyst that facilitates the production of hydrogen from the fuel source. Voluminous reformer chamber designs are provided that increase the amount of catalyst that can be used in a reformer and increase hydrogen output for a given fuel processor size. The burner provides heat to the reformer. One or more burners may be configured to surround a reformer on multiple sides to increase thermal transfer to the reformer. Dewars are also described that increase thermal management of a fuel processor and increase burner efficiency. A dewar includes one or more dewar chambers that receive inlet air before a burner receives the air. The dewar is arranged such that air passing through the dewar chamber intercepts heat generated in the burner before the heat escapes the fuel processor.

The present invention discloses rare earth-doped semiconductor infrared radiation thick-film electronic paste and a preparation method therefor. The electronic paste comprises, in percentage by weight, 10%-90% of an organic vehicle and 10%-90% of a functional phase. The organic vehicle comprises, in percentage by weight, 50%-95% of an organic solvent,1%-40% of a thickening agent, and 0%-5% of an organic additive. The functional phase comprises, in percentage by weight, 40%-95% of a rare earth-doped infrared radiation semiconductor material, 5%-60% of a conductive material, and 0%-20% of a functional additive. According to the electronic paste, the selecting range of a base material is wide, the heating temperature range is wide, the heating efficiency is high, the temperature of a heating body itself is low, and the bidirectional thermoelectric conversion can be achieved. The preparation method comprises: a, mixing the thickening agent, the organic additive and the organic solvent to prepare the organic vehicle; b, mixing and grinding the organic vehicle and the functional phase to prepare the electronic paste; c, printing the electronic paste on a substrate by means of screen printing, and performing curing or sintering to form a film.

Provided is an exhaust emission control device which can properly burn off soot and soluble organic fraction attached to and accumulated on electrodes of a plasma generator. The exhaust emission control device with a post-processing device (catalyst regenerative particulate filter) for allowing exhaust gas to pass therethrough for gas purification incorporated in an exhaust pipe of an internal combustion engine (diesel engine) comprises a plasma generator arranged upstream of the post-processing device for discharging electricity in the exhaust gas to generate plasma, flow-through type oxidation catalyst arranged upstream of the plasma generator, fuel adding means (controller) arranged upstream of the oxidation catalyst for adding fuel into the exhaust gas, temperature increasing means (suction throttling valve or controller) for increasing the exhaust temperature to a level enough for oxidation reaction on the oxidation catalyst of the fuel added by said fuel adding means.

Microwaves are applied to pure water stored in a pure water tank past at least one of the top section of the sealed pure water tank, the side sections thereof and the bottom section thereof, thereby heating the pure water in a non-contact manner.

An image heating apparatus includes an endless belt for heating an image on a recording material at a nip; magnetic flux generating means, disposed opposed to an outer surface of the endless belt, for generating a magnetic flux to cause the belt to generate heat; a metal member disposed inside the belt and supporting a member which is disposed inside the belt; and a magnetic flux reducing member, disposed between the metal member and an opposing portion of the belt which is opposed to the magnetic flux generating means, for reducing a magnetic flux actable on the metal member.

The amount of cooling air (cooling medium) can be reduced, and low-temperature cooling air is prevented from being blown out through film cooling holes. Part of a cooling medium impingement-cooling an inner circumferential surface of a blade main body located on a ventral side further impingement-cools the inner circumferential surface of the blade main body located on a dorsal side and is blown out through film cooling holes in the blade main body that are located on the dorsal side.
