Abstract:
PROBLEM TO BE SOLVED: To provide a microwave heating device capable of heating exhaust gas to a predetermined temperature in a short period of time by making a microwave absorbing heating element efficiently generate heat by small electric power, enabling the miniaturization of a device itself, being effectively mounted even to a vehicle, and heating exhaust gas to the predetermined temperature or higher and efficiently removing a contaminant by improving microwave absorption efficiency, namely, the microwave heat conversion efficiency of the microwave absorption heating element. SOLUTION: The microwave heating device is provided with a plurality of metal vent pipes having axial lines in a direction coincident with an exhaust gas direction and making exhaust gas flow therein in a hollow part of a metal storage body, and a plurality of microwave absorption heating elements 19 provided on the outer circumference surface of each metal vent pipes and radially extending with a predetermined width and at length covering substantially the whole body in an axial direction. Heat is generated by outputting a microwave from a microwave output means and making each microwave absorption heating element absorb the microwave to heat exhaust gas flowing in the vent pipes.

PROBLEM TO BE SOLVED: To efficiently heat a cookware to be heated and cook without being restricted by the material, thickness, and shape or the like of the cookware to be heated, efficiently heating various types of cookwares to be heated according to individual use, reducing the cost by using widely as a heating means of the cookware to be heated, simplifying a control means of reducing the cost of apparatus itself. SOLUTION: The heating cooker includes a shield case which has a bottomed shape with an upper surface opened and is formed of metal material, a microwave oscillation means 11 for outputting a microwave in the shield case, the cookware to be heated, which is mounted in an upper opening part of the shield case, and a microwave-absorbing member mounted, on at least a bottom surface of the cookware to be heated and generating heat by an electric wave absorption action of a microwave output in the shield case. The cookware to be heated is heated to a required temperature to cook by the microwave-absorbing member which generates heat by the electric wave absorption action of the microwaves.

PROBLEM TO BE SOLVED: To provide a snow melting material which reduces labor and time when laid on a road or the like, reduces installation cost and maintenance cost, and achieves high snow melting efficiency.SOLUTION: The snow melting material used on a place which may be loaded with snow, e.g., a sidewalk, a parking lot, a porch, a wall surface or a roof is composed of an SiC sintered body obtained by firing at 1,400-1,500°C, and snow cover or the like is melted by far infrared rays emitted from the SiC sintered body.
Abstract:
PROBLEM TO BE SOLVED: To cool a microwave oscillator effectively while ensuring waterproofness of the microwave oscillator to stabilize output characteristics, to radiate the heat of the air heated by cooling the microwave oscillator effectively to maintain cooling effect, and to simplify a cooling structure of the microwave oscillator to miniaturize it and reduce cost. SOLUTION: This microwave oscillator is provided with an air feeding member for blowing air into the microwave oscillator to cool it and a radiated heat circulating member connected with a terminal side of a microwave guide and a shield box air-tightly and cooling the air to be introduced into the microwave guide after cooling the microwave oscillator by driving the air feeding member when circulating the air from the terminal side of the microwave guide to a shield box side so that the air in the shield box and the microwave guide can be circulated.
