In an induction heater, preheated, pressurized air is further heated in the heating cabinet and also drawn into the coil tube via a suction fan. The simultaneous pulling and pushing of the twice-heated air through the tube provides superior air flow to pick up more moisture from the can ends being dried. The tube ends rest on upwardly concave collars and are held in place by gravity, with a single screw acting as a stop above to prevent upward movement. Removal requires only removing the single screw at each end then lifting the tube straight up out of the cabinet, which is facilitated by providing a hinged cover on the cabinet.

An induction heating cooking device includes a cooking table having an auxiliary slit; an induction coil for generating a magnetic field so as to inductively heat a cooking container placed on the cooking table; multiple light sources disposed at the outside of the induction coil; and a main slit through which light emitted from the light sources passes. The induction heating cooking device forms a virtual flame image on the cooking container, thereby enabling the heating state of the induction heating cooking device to be intuitively checked.

A load abnormality detecting circuit for an inverter to detect abnormality of a load during an operation of the inverter which has a self-arc-extinguishing element as a switching element and a phase synchronizing loop controlling an output frequency to be a resonance frequency of the load, the load abnormality detecting circuit includes a phase shift detection part that detects a phase shift between a gate voltage signal controlling ON/OFF of the self-arc-extinguishing element and an output current of the inverter which is applied to the load, and that sends a first abnormal load signal based on the phase shift.

The subject of the invention is an induction cooking device comprising at least one inductor positioned under a thermally or chemically strengthened glass plate, the composition of the glass being of lithium aluminosilicate type.

An induction heating cooking device includes a cooking table having an auxiliary slit through which light passes; an induction coil for generating a magnetic field so as to inductively heat a cooking container placed on the cooking table; at least one light source disposed at the outer edge of the induction coil; an optical member for changing the traveling direction of light emitted the light source and concentrating the light, and a main slit through which light emitted from the optical member passes so as to form a flame image on the cooking container. The induction heating cooking device forms a virtual flame image on the lower surface of a cooking container at the time of operation of the induction coil, thereby enabling the heating state of the cooking container to be easily recognized.

An example cable assembly includes: a plurality of conductors in a Litz cable arrangement, in which each of the plurality of conductors is electrically insulated from each other over at least a portion of a length of the Litz cable arrangement; a first layer of insulation over the Litz cable arrangement; an inner dielectric jacket over the first layer of insulation; and an outer jacket over the inner dielectric jacket.

A method and apparatus for induction heating or vaporization of water, oil, or other fluids. An induction heater system includes a ferrous heat tube, an induction coil extending around the ferrous heat tube, an induction drive, and a controller to regulate the operation of the induction drive or a fluid supply or both, to heat or vaporize the fluid.

A rack bar includes: a rack tooth row including a plurality of rack teeth meshing with pinion teeth; a hardened layer provided continuously over an entire circumference of the rack tooth row; and a center portion provided inside the hardened layer and having lower hardness than the hardened layer. When the rack bar is viewed in an axial direction of the rack bar, a depth of the hardened layer from the following positions i), ii), and iii) increases in this order: i) a bottom land of the rack teeth; ii) a side of the rack bar relative to the bottom land; and iii) a back of the rack bar relative to the bottom land.
