A heating chamber is divided into a plurality of spaces by barrier sections including a conductive material. Phase shifters having different lengths with respect to a direction and including a dielectric body having permittivity higher than air are inserted in positions of a terminal section, in the spaces except for at least one space, to differentiate positions of bottoms of standing microwaves formed in the respective spaces from each other with respect to the direction. In addition, impedance adjusters having different lengths with respect to the direction and including a dielectric body having permittivity higher than air are inserted in positions on an upstream side of a region passed by the object to be heated, in the spaces except for at least one space, to reduce differences in impedance of the spaces from an entrance of the heating chamber to the terminal section including the phase shifters.

A microwave heating device enhances heating efficiency by a simple configuration. A microwave is led from one end of a conductive heating chamber in direction d. The heating chamber is provided with an opening. A pair of conveying members are provided. A member to be heated sandwiched between the conveying members is moved in direction d, and passes through the opening in direction dnon-parallel to microwave traveling direction d

A microwave heating device includes a microwave generating portion outputting a microwave, a conductive heating chamber into which the microwave is led and having a short-circuited terminal end in a traveling direction of the microwave, and a tuner provided between the microwave generating portion and the heating chamber. The heating chamber has an opening for passing a member to be heated therethrough. The tuner re-reflects the microwave reflected at the terminal end of the heating chamber onto the heating chamber side. The microwave output end of the microwave generating portion and the tuner are connected by a square tubular waveguide made of a conductive material. The tuner and the terminal end of the heating chamber are connected by a square tubular waveguide, which is made of a conductive material except for the opening for passing the member to be heated therethrough.

A classification apparatus including a magnetic stirrer composed of main body () and rotor () and, arranged on the main body of the magnetic stirrer, classification tube (). The interior of the classification tube is provided with classification compartments (A-E) partitioned from each other by divider plates (-). The lowermost classification compartment (A) is furnished with gas emission conduit (). In the classification compartment (A), the rotor () of the magnetic stirrer is arranged. From gas supply source (), a high-pressure gas is fed into the gas emission conduit. By means of the gas emitted from the gas emission conduit, a vortex flow rising from the lowermost classification compartment sequentially toward higher classification compartments is generated in the classification tube. Simultaneously, the rotor of the magnetic stirrer is rotated, so that powdery substance (O) within the classification compartment (A), while being conveyed by the vortex flow, undergoes particle size classification in each of the classification compartments.

An X-ray generator uses a high electrical field generated when a hemimorphic crystal is heated or cooled. The crystal may be lithium niobate polarized in one direction. An X-ray target is placed inside a housing inside which a vacuum is maintained. A tungsten line containing thorium is placed between the crystal and the target. When the crystal is heated or cooled by a Pelletier element, an intense electrical field is generated around the crystal. Thermoelectrons released from the tungsten line accelerate as a result of the electrical field and collide with the X-ray target. The X-rays released at this time radiate through a beryllium window exteriorly of the housing. Intense X-rays are generated without using large scale equipment, such as a high voltage power source.
