A conventional thin-film photoelectric converter using amorphous germanium or crystalline silicon as a photoelectric conversion layer is problematic in that light having a long wavelength of 1100 nm or more cannot be used for photoelectric conversion, and is inefficient. Basically, the present invention relates to a structure and method for forming laminated structures and more particularly to a structure and method for fabricating multi-layer ceramic products using very thin green sheets andor green sheets with very dense electrically conductive patterns on top of a stronger support sheet. The seal is positioned against the interior wall of the tubular body. An output timing-determining device outputs a switch changing-over signal to either one of respective changing-over switches in a changing-over switch circuit. A harness is attached to the flexible plate positioned to expose a patient’s mouth and nose clear of the plate in response to adjusting the harness.
