This invention relates to a corrosion-resistant member comprising a ceramic substrate and a silicon carbide film formed through a chemical vapor deposition process and having a resistivity at room temperature of 20-500 &OHgr;·cm, and a method of manufacturing the same as well as an heating apparatus using the same.
摘要:
A silicon carbide-based porous material is provided, including silicon carbide particles as an aggregate, metallic silicon and an oxide phase containing Si, Al and an alkaline earth metal. The silicon carbide-based porous material is high in porosity and strength and superior in oxidation resistance and thermal shock resistance and, when used as a filter, has a very low risk of fluid leakage causing defects such as cuts and the like, as well as a low pressure loss.

A folder storage device includes a folder storage unit which stores folders with hierarchy structures, a first folder hierarchy information generation unit arranged to generate first folder hierarchy information which indicates a related path and a hierarchical location of each folder based on the folders stored in the folder storage unit, a second folder hierarchy information generation unit arranged to generate second hierarchy information which indicates the hierarchical location of each folder based on the first folder hierarchy information, a display unit which displays the second hierarchy information, and a folder update unit in which contents to be updated of the folders stored in the folder storage unit are specified and the updates of the folders stored in the folder storage unit are executed based on the first folder hierarchy information in response to a receipt of update instructions at a prescribed hierarchical location of the second folder hierarchy information.
摘要:
A ceramic porous body is provided, inclusing a plurality of pores formed in a ceramic substrate at a specified porosity. A pore part is discriminated from a non-pore part by binarizing a cross-sectional plane image of the substrate by image analysis. When a center line passing the central part of the pore part is drawn, the porosity (ε (%)), a mean width (DP (μm)) of the pore part represented by a mean value of a distance, between outlines specifying the pore part, perpendicular to the center line, a mean length (L (μm)) of the pore part represented by a mean value of a length of the center line between adjacent branch points and a length of the center line between an end of the center line and the branch point, and a mean pore size (DH (μm)) satisfy a specified relationship.

A saddle seat type fuel-cell electric vehicle includes a body frame having a pair of right and left main frames connected at their front ends to a head pipe and extending downward therefrom and a pair of right and left under frames connected at their front ends to the head pipe and extending downward therefrom along the right and left main frames on the lower side thereof. A pair of hydrogen cylinders extend substantially vertically along the body frame between the front side of the head pipe and the front side of the front end portion of the footrest so as to interpose the body frame in the lateral direction of the vehicle. A fuel supply unit is provided in a space surrounded by the main frames and the under frames with the hydrogen cylinders being surrounded by a guard pipe connected to the main frames.

摘要:
A highly heat-conductive Si-containing material containing a Si phase whose lattice constant at room temperature is controlled at a level of more than 0.54302 nm but 0.54311 nm or less. Firing is conducted using a kiln material containing no B compound. With this highly heat-conductive Si-containing material and the process for production thereof, a reduction in heat conductivity can be prevented and a high heat conductivity can be exhibited stably.

摘要:
The invention provides a high capacity binary shuttle vector having T-DNA region and Ri ori and capable to integrate a large genome fragment in it; a genomic library having the ability to transform a plant, especially monocotyledonous ones; a plant transformed with the high capacity binary shuttle vector; and a method of searching for a useful gene by use of the above vector. The present high capacity binary shuttle vector can introduce a large genome fragment of 10 kb or more, easily, efficiently and stably into a plant, especially monocotyledonous ones under those conditions in which the rearrangement or deletion of these genome fragments does not occur. The invention also provides some other vectors derived from the above Ri ori driven vectors, which can integrate circular genome library plasmids with a lox site, or which can efficiently transform plants with genes of arbitrary expression properties. The invention includes also the assessment method for the functions of genome fragments inserted in the above vectors by complementation assay. In addition, a useful gene or gene complex can be efficiently examined so its isolation is also made easy.
