Abstract: By rotating a second camera (4) by a hinge (5) by 180 degrees so as to obtain an opening state, the second camera 4 faces a surface side. As a result, a first camera (3) and the second camera (4) are aligned horizontally, and use the same direction as a photographing range. When the second camera (4) is rotated, a system controller determines that a state is in a stereoscopic vision photographing mode. When a camera shutter is operated by a user, both the first camera (3) and the second camera (4) are allowed to perform a photographing process, and obtained two image data are stored in a memory after being attached to information indicating that the image is for the right eye and the image is for the left eye, and etc. Then, the two image data are transmitted by an e-mail function to a terminal of a communicating partner.

Abstract: There is disclosed a stirling system in which a rotary-type high-temperature expansion mechanical section, a rotary-type low-temperature compression mechanical section and a driving shaft common to both the mechanical sections are stored in a sealed container to achieve remarkable simplification and improvement of durability. In the stirling system, the rotary-type high-temperature expansion mechanical section and the rotary-type low-temperature compression mechanical section for constituting a stirling cycle, and the driving shaft common to both the mechanical sections are stored in the sealed container. The sealed container is divided into a rotary-type high-temperature expansion mechanical section side and a rotary-type low-temperature compression mechanical section side by a partition wall.

Abstract: An illuminating device (1) is formed of a light source (12) in which LED chips (11) are arranged in an array shape and lens cells (14) are arranged on a light-emission side of each of the LED chips (11), and a pair of fly's eye lenses (13) that integrates and guides to a liquid crystal panel (3) the light emitted from each of the LED chips (11) and collimated by the lens cells (14). The LED chip (11) and the lens cell (14) are formed in a square shape, and an aspect ratio thereof corresponds to that of the liquid crystal display panel (3). In addition, the lens cells (14) are arranged separately from one another in such a manner to have wall surfaces (air gaps), and the wall surfaces serve as reflective surfaces.

Abstract: To provide a hydrogen generator for a fuel cell for generating a hydrogen-rich gas by steam reforming a source of hydrocarbon fuel gas and supplying the hydrogen-rich gas to a fuel cell or the like to make it possible to efficiently heat a reforming catalyst in a reforming pipe by a combustion gas. A reforming pipe in which a reforming pipe is formed by filling a reforming catalyst between an erect pipe and a polygonal or wavelike outer pipe surrounding the erect pipe and an outermost pipe in which vertexes of the polygonal or wavelike outer pipe are inscribed to the contour of the reforming pipe are set to form a route of a reformed gas between the outer pipe and the outermost pipe. It is preferable to concentrically arrange a combustion pipe, the reforming pipe, the outermost pipe, the heat insulating means, a CO transformer, a first spatial portion, a CO eliminator, a second spatial portion, and a vessel in order.

Abstract: A solar battery indicator apparatus utilizing a capacitor for accumulating electrical power generated by the solar battery and light emitting diodes for emitting light on the basis of the electrical power supplied from the capacitor. An indicator body makes a prescribed indication on its front surface through the use of optical fibers. Several bundles of optical fibers are utilized with each bundle being associated with a plurality of optical fibers having one of their ends disposed to face an associated one of the light emitting diodes and the other end of each of the bundles of fibers being associated with a particular indicator. The configuration of optical fiber bundles utilize a control portion for controlling light emitting states of respective individual light emitting diodes.
