Abstract:
A photosensitized composite material and a material, an element, a device, and the like, which employ the photosensitized composite material, are provided. In the photosensitized composite material, multiphoton absorption compounds are highly sensitized for practical use by utilizing an enhanced plasmon field. The photosensitized composite material has a structure where the multiphoton absorption compounds are linked to the surface of a fine metal particle through linking groups. The fine metal particle generates an enhanced surface plasmon field in resonance with a multiphoton excitation wavelength. The multiphoton absorption compounds have a molecular structure enabling multiphoton absorption. The photosensitized composite material is contained in or used for, for example, a three-dimensional memory material and a three-dimensional recording medium, an optical power limiting material and an optical power limiting element, a photocuring material and a stereolithography system, and a fluorescent material for a multiphoton fluorescence microscope and a multiphoton fluorescence microscope.

Abstract:
A variable capacity viscous heater whose capacity is reliably decreased and whose heating efficiency does not lower even after a long term use. Formed are, for example, a recovery passage (3a) communicating with the central area of a heating chamber (10) and capable of being opened and closed, a supply passage (3c) communicating with the lower portion of the heating chamber (10), and a control chamber (CR) communicating with the recovery passage (3a) and the supply passage (3c). Silicone oil in the heating chamber (10) is recovered by use of the Weissenberg effect into the control chamber (CR) through the recovery passage (3a), which is open, to decrease the capacity. Silicone oil in the control chamber (CR) is fed into the heating chamber (10) through the supply passage (3c) to increase the capacity.
