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 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.

Abstract:
PROBLEM TO BE SOLVED: To provide an earthquake-resistant exterior fence capable of being constructed even in a narrow place, and a method for constructing the earthquake-resistant exterior fence.SOLUTION: An earthquake-resistant exterior fence comprises a steel pipe pile 1 that is driven into the ground, a vertical support 2 that is fixed to the steel pipe pile 1, and a fence member 4. The fence member 4 and the vertical support 2 are coupled together by infilling a filler between the fence member 4 and the vertical support 2 and solidifying the filler. Base concrete and a buttress can be dispensed with, and the earthquake-resistant exterior fence can be constructed even in a narrow place. Possession of vertical and horizontal great strength can prevent the earthquake-resistant exterior fence from collapsing due to earthquakes.
