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: [Problem] To provide a digital camera that enables, using a simple configuration, a digital display to be easily and freely rotated in the horizontal and vertical directions. [Solution] A digital camera (1) is provided with the following: a camera main body (2) having an image pickup lens; a liquid crystal display (3) that displays the images picked up by the image pickup lens; and a hinge unit (4) that connects the camera main body (2) and the electronic display (3). The camera main body (2) includes a first slit (22) that is formed by cutting out at least a portion of an inner circumferential wall (21a) of an accommodating depression (21) which accommodates the hinge unit (4), and that causes an outer circumferential surface (4a) of the hinge unit (4) to be exposed to the outside.

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.

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: Disclosed is a stereoscopic imaging device which answers the need for system compatibility over the entire range of long-distance (telescopic) imaging to close-up imaging, and which can faithfully reproduce stereoscopic images on the display side without adjustment. To that end, stereoscopic imaging device is disclosed in which the imaging lens optical axes (phi (L), (R)) in an imaging unit provided with imaging lenses and imaging elements (S) are arranged so as to be laterally parallel, and the distance between the optical axes (DL) is set to the interpupillary distance (B) of a human. One reference window (Wref) is defined as a virtual view frame in the image viewfield of said imaging unit.

Abstract: A problem to be solved is to enhance the charge and discharge characteristics and rate characteristics of a B-type titanium oxide (TiO2(B)) powder by a simple treatment and to provide a B-type titanium oxide powder that can be suitably used as a negative electrode material for a lithium ion battery. A B-type titanium oxide powder is allowed to undergo a reaction under a fluorine-containing gas atmosphere at 0° C. to 200° C. for 1 minute to 10 days to obtain a surface-fluorinated B-type titanium oxide powder. It is preferred that the fluorination treatment is performed at 0.01 atm to 2 atm. It is preferred that a gas containing a fluorine compound selected from a fluorine (F2) gas, a nitrogen trifluoride (NF3) gas, a perfluorotrimethylamine (N(CF3)3) gas, a chlorine trifluoride (ClF3) gas and the like is used as the fluorine-containing gas.

The image pickup substrate moves in parallel with a correct horizontal posture being kept up or down by turning the pinion shaft. A horizontal rack is provided at an upper part on the backside of the image pickup substrate, and performs a right and left shift by operating a vertical pinion shaft which is engaged therewith.
