Abstract: The present invention provides a microwave treatment apparatus capable of suppressing the occurrence of sparking in a vessel. A microwave treatment apparatus 1 includes: a vessel having a pillar-shaped hollow portion configured to contain a liquid-phase content to be subjected to batch processing using microwaves, and an upper inner face whose height decreases along a direction from a central axis of the hollow portion to the periphery when the vessel is located such that a direction along the central axis is along a vertical direction; a microwave generator that generates microwaves; and a waveguide having a portion protruding from the upper inner face into the hollow portion, and configured to introduce microwaves generated by a microwave generator into the hollow portion.

Abstract: Provided is a microwave treatment apparatus that can properly treat a treatment target using microwaves. The apparatus includes: a vessel 10 in which a treatment target 2 is arranged; a microwave irradiating unit 20 that irradiates an internal portion of the vessel 10 with microwaves; and heat generating member 30 that is provided inside the vessel 10 along the treatment target 2, generates heat by absorbing part of microwaves used for irradiation by the microwave irradiating unit 20, and transmits part of the microwaves. The microwave irradiating unit 20 irradiates a portion in which the heat generating member 30 is provided with microwaves, thereby heating the treatment target 2 from the outside through heat generation at the heat generating member 30, and directly heating the treatment target 2 with microwaves transmitted through the heat generating member 30.

Abstract: A waveguide connecting apparatus including two waveguide connecting clamps each including a pair of clamp pieces positioned to oppose each other and sandwich outer peripheral portions of flanges positioned to oppose each other. A fastener pressing the pair of clamp pieces against the outer peripheral portions of the flanges. Each clamp piece includes two abutting members having first faces abutting against faces on the opposite side of faces that oppose each other of the flanges positioned to oppose each other. Second faces abutting against side faces of the waveguides, and third faces serving as tapered faces of the flanges, on the opposite side of the faces opposing each other. A pressing member with a substantially V-shaped cross section, having two inclined faces engaging with the respective third faces of the abutting members, and holding the two abutting members such that the two abutting members are respectively movable in the directions of inclination of the inclined faces with which the two abutting members respectively engage. The two waveguide connecting clamps are positioned such that directions in which the pairs of clamp pieces oppose each other intersect each other.
