Title: Game apparatus and information storage medium
Inventor: OUCHI SATOSHI
IPC: A63F13/525
Filed: 2000-05-10
Abstract: PROBLEM TO BE SOLVED: To reduce the whole of processing relating to the formation of image for an object within a virtual three-dimensional space, without the need to dispose a substitute model in the virtual three-dimensional space. SOLUTION: A virtual three-dimensional space containing positions 20a, 20b where a model is to be disposed is set. By performing a geometrical processing such as see-through projection conversion, the virtual three- dimensional space (actually, apexes of each polygon existing in the virtual three-dimensional apace) is converted to a visual point coordinate system of a virtual camera. In that case, since a position where the model is to be disposed is one point, a geometrical processing is applied to the one point to determine a position for insertion for a model image of the model. The model image is drawn (colored) based on position coordinates of the determined visual point coordinate system, while each object (polygon) present in the virtual three- dimensional space is colored, whereby a rendering process is performed to produce a display image data per one frame.

Title: Fuel reformer
Inventor: INOUE MASAHIRO
IPC: C10L1/00
Filed: 2000-05-24
Abstract: PROBLEM TO BE SOLVED: To provide a fuel reformer cooling a reformed gas at a proper temperature and preventing generation of condensed water in both a shift reaction section to which a cooled reformed gas is supplied and a CO concentration reduction section. SOLUTION: The reformed gas discharged from the reforming reaction section 32 is cooled through the heat exchange section 36 comprising the first heat exchange section 40, the second heat exchange section 50 and the third heat exchange section 60 and is supplied to the shift reaction section 70. While causing the third heat exchange section 60 to function as a condenser to condense the water contained in the reformed gas, the condensed water is stored in the sump section 62 and is recovered into the water tank 22 through the drain port 63. Thus, this process can definitely prevent the condensed water from being transferred to the shift reaction section 70 or to the CO reduction section 74, thereby keeping dry the shift catalyst and the preferential oxide catalyst whose functions may not be deteriorated.  Since the recovered water can be reutilized as a reforming material, the economic effect of resources can be further enhanced.
