摘要:
A hand-held game apparatus and a game program are provided which allow a user to play a game while going back and forth between a narrow-range image and a broad-range image of map. The user can manipulate a touch panel which mounted on a display section for displaying the broad-range image. If the user manipulates the touch panel to point to a coordinate position on the broad-range image, thus designating coordinates for the narrow-range image, a changed narrow-range is displayed. If the user indicates a moving direction on the broad-range image, thus designating a scroll direction, the displayed broad-range image is moved (scrolled).
摘要:
An electrode for active oxygen species comprising a conductive component with a polymer membrane of a metal porphyrin complex formed on the surface is disclosed. The electrode for active oxygen species can detect active oxygen species such as superoxide anion radicals, hydrogen peroxide, and .OH and other active radical species (NO, ONOO—, etc.) in any environment including in vivo environment as well as in vitro environment. The electrode thus can be used for specifying various diseases and examining active oxygen species in food or in water such as tap water and sewage water.

摘要:
Cross-liked resins exhibiting a high level of optical transparency and little variation of refractive index with temperature are prepared using mixtures of two organosiloxane resins in combination with a reinforcing silica filler. The types and relative concentrations of hydrocarbon radicals in the resins are within specified limits to obtain the required optical properties and each resin contains groups that react with groups on the other resin to form a crosslinked network.

Using a silicon-containing carbon-based composite material represented by the compositional formula: SiOxCyHz. In this formula, “x” is from 0.8 to 1.7, “y” is from 1.4 to 7.5, and “z” is from 0.3 to 1.3. The composite material is preferably obtained by: obtaining a cured product by crosslinking (A) a crosslinkable group-containing organic compound, and (B) a silicon-containing compound capable of crosslinking the crosslinkable group-containing organic compound, and heat treating the obtained cured product. The composite material of the present invention has high reversible capacity and stable charge and discharge cycle characteristics, and has high initial charge and discharge efficiency. Therefore, the composite material of the present invention is suitable for an electrode of an electricity storage device, particularly of a lithium or lithium-ion secondary battery.

A hand-held game apparatus and a game program allow a user to play a game while going back and forth between a narrow-range map and a broad-range map. The player can manipulate a touch panel mounted on a display for displaying the broad-range map. If the player manipulates the touch panel to point to a coordinate position on the broad-range map, thus designating coordinates for a narrow-range map to display, an image of the narrow-range map, which is changed as desired, is displayed. If the player indicates a moving direction on the broad-range map, to designate a scroll direction, the displayed broad-range map is moved (scrolled).
