Abstract: A platinum core-shell catalyst that uses palladium (Pd) as a core metal, or a platinum catalyst containing platinum and a metal besides platinum is manufactured industrially on a mass scale. The platinum catalyst is supported on carbon and has excellent oxygen reduction activity. The platinum catalyst is made for a fuel cell by bringing about the presence of a chemical species imparting higher potential than the initial oxide formation potential of the platinum of the platinum catalyst, and by bringing about the presence of a chemical species imparting lower potential than the initial oxide formation potential of the platinum of the platinum catalyst. The manufacture is carried out in a dispersion solution of the platinum catalyst dispersed in an acidic solution containing protons.

Abstract: An infrared polarizing filter is attached to an infrared synchronization signal radiator of a stereoscopic image display device which alternately displays right and left images by time-division with polarized light in one direction to radiate the polarized-light infrared synchronization signal. The problem with the occurrence of crosstalk is solved. Stereoscopic image appreciation eyeglasses have polarizing plates, visual field opening/closing liquid crystal cells and tilt correcting liquid crystal cells. The synchronization signal is received by a receiver mounted on an eyeglass frame. The tilt correcting liquid crystal cells are adjusted based on the eyeglass frame tilt angle detected.

Abstract: A stereoscopic video imaging display. A virtual field-of-view frame or reference window is set in a field of view of a stereo camera. Standard stereoscopic video data is sent. On a display side, stereoscopic videos are alternately displayed in a time-division manner with a width in a left view angle determined by lines connecting both ends of a reference dimension display screen and a left eye of an observer and in a right view angle determined by lines connecting both the ends of the reference dimension display screen and a right eye of the observer. Thus, the left and right videos are displayed at a position where they partially overlap each other, thereby allowing the stereoscopic video equivalent to the reference dimension display screen to be viewed.

Abstract: A virtual field-of-view frame or reference window in a field of view of a stereo camera, and projected in a reduced manner by left and right shooting lenses to form an image on each of a left and right image pickup devices. Standard image data and stereoscopic video data is sent. The standard stereoscopic video data is displayed on a display screen having positions of left and right screens exactly matching each other and having the position and size for reproducing and displaying the reference window as a reference dimension display equivalent to the reference window, simultaneously with left and right polarizations. With eyeglasses for field-of-view separation left and right videos are separately viewed.

Abstract: A stereoscopic imaging display. A virtual field-of-view frame or reference window is set in a field of view of a stereo camera. Standard stereoscopic video data is sent. A stereo slide or a stereo photo print is formed with left and right images from the standard stereoscopic video data. Spacing DP2 between the left and right images is determined by the equation DP2=B(1?L2/L0), where B is a human interpupillary distance, L2 is a view distance, and L0 a distance from the human interpupillary distance to a reference dimension display screen which is equivalent to the reference window at the time of photographing being taken.
