An electron beam generator device includes a base body having a conductive surface and a electron-emission electrode having a carbon nanotube structure on the conductive surface of the substrate. The carbon nanotube structure constitutes a network structure which has plural carbon nanotubes and a crosslinked part including a chemical bond of plural functional groups. The chemical bond connects one end of one of the carbon nanotubes to another one of the carbon nanotubes. A method for producing an electron beam generator device, includes applying plural carbon nanotubes each having a functional group onto a conductive surface of a base body, and crosslinking the functional groups with a chemical bond to form a crosslinked part, thereby forming a carbon nanotube structure constituting a network structure having plural carbon nanotubes electrically connected to each other.

There is provided a cerium-based abrasive containing cerium oxide as a main component, in which the abrasive particles composing the abrasive are coated with a coating layer containing at least either one of a silicon component of silicon or a silicon compound and an aluminum component of aluminum or an aluminum compound. The cerium-based abrasive can be produced by wet-dispersing the cerium-based abrasive in a dispersion medium to obtain a slurry and carrying out surface treatment by adding a treatment solution containing at least either one of the silicon compound and the aluminum compound to the slurry. Further, the cerium-based abrasive can be produced by carrying out surface treatment by adding a treatment solution containing at least either one of the silicon compound and the aluminum compound to the slurry during the pulverization step or after the pulverization step in the conventional cerium-based abrasive production process and after that roasting and classifying the obtained cerium-based abrasive.

An MRI apparatus is characterized in that magnet members for compensating the magnetic field are disposed to a thermal shield system of the superconducting apparatus. It is another feature of the present invention that the magnet members for compensating the magnetic field are disposed at positions where temperature change in the vacuum chamber is not transferred to the interior of the vacuum chamber.

An object of the invention is to provide a quartz glass crucible for pulling up silicon single crystal and a method for producing the same, suitable for improving the productivity of the crucible and the quality of the silicon single crystal, which, by forming a crystalline layer on the inner surface of the quartz glass crucible during pulling up silicon single crystal, prevents degradation from occurring on the inner surface of the crucible and increases the ratio of single crystal while preventing the dislocation from forming on the single crystals. The objects above have been accomplished by a quartz glass crucible for pulling up silicon single crystal, having a double layered structure comprising a naturally occurring quartz glass outer layer and a synthetic quartz glass inner layer, said synthetic quartz glass inner layer contains at least one type of an alkali metal ion selected from the group consisting of Na ion, K ion, and Li ion, which is diffused or moved from said naturally occurring quartz glass outer layer into said synthetic quartz glass inner layer.

Disclosed are a method for activating lipid metabolism in the small intestine epithelium and also a method for promoting accumulation of fatty acids into the small intestine epithelium, each of which features administering an effective amount of a diacylglycerol. Also disclosed are methods for improving various symptoms in diabetes, which have ingesting a diacylglycerol. Ingestion of the diacylglycerol leads to accumulation of the fatty acids in the small intestine. The fatty acids so accumulated promote induction of β-oxidation, thereby not only activating lipid catabolism but also making it difficult to allow lipids to accumulate as triacylglycerols. This series of actions eventually results in development of lowering action for blood remnant-like lipoprotein level and also lowering action for blood leptin level, and hence, lipid metabolism is improved. Further, energy consumption is enhanced by promoting the induction of β-oxidation and activating lipid catabolism.

The MRI apparatus has ring-shaped superconducting coils arranged to vertically oppose each other. The superconducting coils are installed in ring-shaped cooling containers. The cooling containers are accommodated in radiation shield plates. The radiation shield plates are accommodated in vacuum vessels. The cooling containers are connected together at at least two locations. Support members are arranged between an outer wall surface of the lower cooling container and an inner wall surface of the lower vacuum vessel to support the lower cooling container on the lower vacuum vessel. The upper cooling container is free, supported only by the connecting tubes connecting the upper and lower cooling containers.
