  • Patent number: 9253824
    Abstract: A small steam generator uses a cylindrical steam generation vessel having a steam generation portion formed to store an amount of water for generating steam and a steam passage portion formed on the upper end of the steam generation portion for spouting steam generated in the steam generation portion. A heater element is disposed within the steam generation vessel, and an induction heating coil is wound around the periphery of the steam generation vessel for energizing the heater element. The heater element is energized by supply of electric power to the heating coil so that steam generated by boiling of the water in the steam generation portion spouts upward from the steam passage.

  • Publication number: 20150346464
    Abstract: A zoom lens is a projection lens which is composed of a negative first lens group, a negative second lens group, a positive third lens group, a negative fourth lens group, a fifth lens group, and a positive sixth lens group in order from the enlargement conjugate side, and changes magnification by changing the intervals between the lens groups. At least the second, third, and fifth lens groups move when the magnification is changed, and the third lens group moves from the enlargement conjugate side to the reduction conjugate side when the magnification is changed from a telephoto end to a wide angle end. An aperture stop is disposed between the surface closest to the reduction conjugate side of the third lens group and the surface closest to the enlargement conjugate side of the fifth lens group, and is approximately telecentric on the reduction conjugate side.
