A fuel cell system includes a fuel cell constructed by plural stacked cells, a circulation path through which a thermal medium is circulated into each cell, a heater for heating the thermal medium, a bypass path through which the thermal medium is circulated into a part of each cell while bypassing the other part thereof, and a flow control valve for controlling a flow amount of the thermal medium circulated in the bypass path. The thermal medium can be circulated into only the part of each cell in a warm-up operation, so that the part of each cell is collectively heated. An amount of the thermal medium circulated into the other part of each cell is controlled, so that all of each cell is finally warmed up in the warm-up operation.

An apparatus and method for forming a composite workpiece are provided. An electromagnetic field generator induces a current in a susceptor, thereby heating the workpiece in a die cavity. An elastomeric bladder in the cavity is inflated and urges the workpiece against a contour surface corresponding to a desired configuration of the workpiece. Coolant fluid can also be circulated through the die cavity to cool the workpiece. Thus, the workpiece can be heated, formed, and cooled quickly and without substantial heating of other components, thereby reducing the time and energy relative to conventional forming methods.

A tamper-evident rigid plastic food container system wherein the outer periphery of the mating surfaces of the lid and tray are permanently bonded together after the food product has been placed in the tray, a set of perforated rows at an inner periphery, the interconnect of which needs to be torn into order to open the lid.

Method and apparatus for disinfecting and/or sterilizing a root canal system by targeting the water content of disease and debris in the canals. The laser technique of employs a frequency of the wavelength emissions between about 930 to about 1065 nanometers with an optimum of 980 nm. This range of wavelengths targets the water content of tissue cells and pathogens as well as any residual organic debris in water within the root canal system after its preparation while being poorly absorbed by the surrounding dentin. The selection of the optimum wavelength produces significant effects generating and advancing treatment to the targeted aqueous environments. This is due to the rapid energy absorption by the water and the subsequent creation of gas bubbles, liberation of heat and subsequent propulsion of waves of heat and gas that impact along the canal walls and ramifications resulting in an enhanced bacterial kill and cleaning of the canal walls and ramifications. No dyes or other additives are necessary to enhance the effectiveness of the laser kill of bacteria, etc.

Two axial fans (82, 83) integrated with the outer rotor side flanges and two axial fans (95, 96) coupled with the inner rotor shaft work in series and produce continuous internal close-loop air circulation between both rotors and between the outer rotor and the motor enclosure, for improving the rate of heat transmission from the rotors to the motor enclosure. If the outer rotor is selectively immobilized, the two inner rotor axial fans produce the internal close-loop air circulation.
