  • Publication number: 20170045847
    Abstract: A fixing apparatus includes a belt including a ferromagnetic layer. A ferromagnetic plate is disposed inside the belt and has a Curie point that is lower than a Curie point of the ferromagnetic layer. An induction heater causes heat generation in the ferromagnetic layer and the ferromagnetic plate. The induction heater includes a coil. A driving circuit outputs a high frequency current to the coil, and changes the high frequency current. A temperature sensor measures a temperature of the coil. A controller controls the driving circuit to decrease the high frequency current if the temperature of the coil measured by the temperature sensor is higher than a predetermined value.

  • Publication number: 20150272835
    Abstract: Methods of obtaining a carotenoid-containing composition were developed, in which degradation of carotenoids is suppressed even though extraction and purification are performed on a culture of microorganism that produces carotenoids including astaxanthin by simple steps using a lower alcohol which is a conventionally known solvent, and the compositions have high astaxanthin content and contain highly pure carotenoids and also have satisfactory crystal properties. Further addition of a simple step that promotes isomerization of astaxanthin successfully improved the carotenoid yield.
