A split-opening portion is formed by two transverse breakable portions that extend substantially along the transverse direction of a vehicle, two front-rear breakable portions that extend substantially along the front-rear direction of the vehicle and are connected to the transverse breakable portions, and a middle breakable portion that is located between the two transverse breakable portions and extends substantially along the transverse direction of the vehicle. The middle breakable portion is connected to the front-rear breakable portions. In a front passenger seat airbag apparatus, the split-opening portion is broken by pressing force of an inflated airbag so that door portions are separated from the door adjacent portion, and the door support portions are pivoted together with the door portions about hinge portions serving as fulcrums. The breaking strengths of parts of the split-opening portion are varied such that is broken in the order of the transverse breakable portions, the front-rear breakable portions, and the middle breakable portion.

A data conversion apparatus for converting index data to real data and an image generation apparatus for converting index texture data to real texture data by the data conversion to make it possible to suitably carry out texture mapping. A data conversion apparatus comprises a first memory and a second memory each for storing data having a n bit width and in which any data is stored, an address detecting means for detecting addresses of the first memory and the second memory based on input data, a data reading means for reading data stored at the detected addresses of the first memory and the second memory, a first data selecting means for selecting either of the data read from the first memory or the data read from the second memory, a data extending means for extending the selected data to data having a 2×n bits width, and a second data selecting means for selecting either of the first data formed by connecting the data output from the first memory and the data output from the second memory or the second data of the extended data.

A sharpened metallic probe having a top of main body including a carbon-containing metal and a method and an apparatus for fabricating the metallic probe. A metallic probe with an extremely sharpened tip is obtained by inducing a field emission from the tip of the main body of the metallic probe where a nanotube is joined thereto, heating and melting locally the tip of the main body of the metallic probe by a Joule heating, and tearing the nanotube toward a counter electrode by a Coulomb attractive force.

A pattern formation method wherein a very small pattern composed of a desired element (atoms) is formed directly on a substrate by using atomic beam hologram technology. Quantum coherent reflection of an atomic wave is utilized. A coherent atomic beam is irradiated as a material wave, for example, upon a hologram of the transmission type to modulate the atomic beam with pattern information included in the hologram. The atomic beam having passed through and diffracted by the hologram is introduced to a reflecting plane so that the atomic beam may be quantum coherent reflected by the reflecting plane, and the atomic beam thus reflected is introduced into a substrate. A binary (two-value) hologram produced by computer synthesis is used suitably as the hologram. A hologram of the potential control type may be also used.
