An article transferring device that transfers articles includes: a traveling rail; primary-side stators; a power source; a first transporting carriage and a second transporting carriage each of which includes a secondary-side movable element and transports an article by the secondary-side movable element receiving a magnetic action from the primary-side stators. Each of the first transporting carriage and the second transporting carriage is caused to travel so as to be stopped or change a traveling speed individually by a ground primary-side linear motor system including the primary-side stators and the secondary-side movable element, and further includes a transferring unit that transfers the article in an intersecting direction intersecting with the predetermined path by receiving force from the power source.

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 mast includes two support columns each having nonuniform strength in a height direction. Both of upper and lower end portions of the mast have the highest strength, intermediate portions of the mast have the intermediate strength, and shoulder portions of the mast, between the central portion and both of the upper and the lower end portions, have the lowest strength.

Guide tracksprojecting in a vertical direction are provided in a right and left of a running trackand left and right guide rollersare provided on a track guided vehicle and guided using inner surfaces of the left and right guide tracks. Branching rollerseach comprising elevating and lowering means are provided in the right and left of the track guided vehicle and outside the right and left guide tracks. Thus, branching and rectilinear progression of the track guided vehicle is controlled by switching between a state where the branching rollersare elevated or lowered to guide the track guided vehicle using outer surfaces of the guide tracksand a state where the branching rollersdo not contact with the outer surfaces. Whether the track guided vehicle runs straight or shifts to a branch line can be controlled by contacting one of the branching rollerswith the outer surface of the corresponding guide tracks, which guide the guide rollersin the section (rectilinear progression section) different from the branching portion

A height sensorand an image recognizing sectionare installed in a teaching unit; the height sensorcontacts a pinon a load portto detect the height position of the pinand the image recognizing sectionrecognizes a pinand thus its horizontal plane position. A platformof an overhead travelling carriagegrips and lowers the teaching unittoward the load port. The height sensorthen detects the height of the load port. Then, the teaching unitis slightly raised. The horizontal plane position of the pinis recognized and averaged over a time equal to at least the vibration period of the platform. As a result, the position of the load port can be accurately taught to the overhead travelling carriagewithout preparations such as the installation of marks on the load port.

The present invention enables a member to be accurately fixed to a floor. With tapped holes in a member mounting section accurately aligned with marks formed in a grating so as to correspond to through-holes a bolt is screwed in an internal thread cylinder (fixed in a vent hole in the grating ) through a through-hole in a presser plate that can have its position changed relative to the member mounting plate and the presser plate is used to fix the member mounting plate to the grating
