A heating roller performs electromagnetic induction heating, and includes a first exciting coil that heats the heating roller, a first degaussing coil that decreases magnetic fields of the first exciting coil, and a first axial direction core that guides magnetic fluxes, to make up a magnetic circuit between the first axial direction core and the heating roller. The width of a heat zone is controlled in agreement with a sheet feeding area. Thus, the capability to control a temperature increase in a non-sheet-feeding area of the heating roller is enhanced. Power can be saved during continual feeding of small recording sheets.

A heat generating roller, fixing equipment and an image forming apparatus in which warm-up time is shortened while preventing excessive temperature rise and good fixing performance is realized by preventing offset. The heat generating roller is formed principally by laying a high permeability conductive layer and a nonmagnetic conductive layer in layer. When a voltage is applied from a power supply to an exciting coil and an alternating current flow, magnetic flux is generated around the exciting coil and a magnetic field is formed. Magnetic coupling of a system including the heat generating roller and the exciting coil is advantageous at a low temperature and heat generation of the heat generating roller is accelerated. When the Curie point is exceeded, skin depth increases and skin resistance decreases, which suppresses generation of Joules heat and reduces heat generation of the heat generating roller.

There are disclosed an apparatus for mounting electronic components, with which the electronic components can be reversed, up and down, and mounted onto a circuit board in a short mounting process time by performing picking up, delivering and receiving of components between heads, and mounting of the components onto the circuit board in parallel. A plurality of reverse-supply heads are mounted on a component supply holder for performing indexing rotation, while a plurality of mounting heads are mounted on a component mounting holder for performing indexing rotation in synchronization with the indexing rotation of the component supply holder. By (i) picking up an electronic component, (ii) delivering the electronic component from the reverse-supply head to the mounting head, and (iii) mounting the electronic component onto the circuit board at prescribed positions, operations from (i) to (iii) can be carried out in parallel. Thus, the electronic components can be mounted onto the circuit board in a short process time.

The present invention provides a reflow apparatus and method effective to make constant the internal gas flow direction in a heating section within a reflow furnace. A circulating gas path is formed in a heating unit which collects and causes the gas to flow from a sirocco fan, up the rear side of the heating unit and then down towards a circuit board moving along a transfer path at the front side of the heating unit. Moreover, a plurality of straightening plates are arranged above the transfer path of the heating unit so as to guide the hot gas, which is flowing forwardly downwardly toward the circuit board moving along the transfer path. A blow-down nozzle is provided and includes a plurality of plates aligned in rows in the transferring direction of the circuit boards. The plates have an inverse U-shaped cross section. The blow-down nozzle is arranged below the straightening plates to cause the vertical hot gas flows to flow uniformly over the whole surface of the circuit board.
