Abstract: A formic acid producing apparatus comprising a closed formic acid synthesis reaction section to which an ionic liquid, hydrogen, and carbon dioxide are introduced externally, and in which formic acid is synthesized.

Abstract: An object of the present invention is providing a method for producing formic acid under mild reaction conditions and by a simple procedure. As a means for achieving the object, the method for producing formic acid of the present invention is characterized by a reaction between carbon dioxide and hydrogen in the presence of an ionic liquid. According to the present invention, it is possible to generate formic acid effectively, because the method does not require that carbon dioxide be brought into a supercritical state and because no basic substances are required to be added to the reaction system.

Abstract: An object of the present invention is to provide a method for producing hydrogen by using formic acid as a feedstock, which provides a solution to problems to be solved for the production of hydrogen on an industrial scale, such as problems of production cost, storability and transportability, and also offers improved convenience. The method for producing hydrogen of the present invention is characterized by heating an ionic liquid containing formic acid. The ionic liquid is preferably an ionic liquid in which a counteranion is a formate anion (i.e., formic acid salt). Such an ionic liquid is, as a medium for the production of hydrogen from formic acid as a feedstock, excellent in terms of reaction selectivity (high-purity hydrogen is produced) and reaction velocity.

Abstract: A hydrogen generation system includes a hydrogen generation reaction section for containing a liquid mixture of formic acid and an ionic liquid, and decomposing the formic acid into hydrogen and carbon dioxide by heating; and a separation section for separating a mixture of hydrogen and carbon dioxide supplied from the hydrogen generation reaction section into hydrogen and carbon dioxide, wherein after the separation, the hydrogen is sent out of the separation section to an external hydrogen destination, and the carbon dioxide is sent out of the separation section to an external carbon dioxide destination or emitted into the atmosphere.

Abstract: An NMR probe for high-temperature NMR measurements includes tubular heating means mounted respectively immediately below and immediately above an area to be measured. A sample tube is inserted inside the tube formed by the two heating means. A sample placed in the sample tube is heated. Heat from the two heating means is transmitted to the sample via at least one heat transfer pipe of a good thermal conductivity. The heat transfer pipe is disposed inside the tube of the heating means.

Abstract: An optical disk includes a user accessible area having a plurality of blocks and flag data recorded on the optical disk. The flag data indicates whether or not each of the blocks is in an erased state in which there is no recorded data. A flag area stores the flag data, and area data indicating that the optical disk has the flag area is recorded on the optical disk.

Abstract: In a method for preventing unauthorized use of a recording medium having a user accessible area and a user inaccessible area, first information is read from the user inaccessible area of the recording medium. The first information is compared with second information concerning a true recording medium (lawfully produced copy). It is then concluded that the recording medium is the true recording medium when the first information corresponds to the second information.

Abstract: A CD-ROM stores encrypted software. When a user desires to decrypt and install this software, an approval preparatory key is generated by an installer. This approval preparatory key is generated based on time data. When the user informs a center of this approval preparatory key, the center calculates a difference between this approval preparatory key and a decrypting key and vends this calculated result to a user in the form of an approval key. When the user inputs this approval key to an installer, the installer generates a decrypting key by adding the approval preparatory key to the approval key. The installer decrypts the software by this decrypting key and installs the encrypted software into a personal computer system.

The flag data indicates whether or not each of the blocks is in an erased state in which there is no recorded data. A flag area stores the flag data, and area data indicating that the optical disk has the flag area is recorded on the optical disk.

Abstract: An optical disk is divided into a plurality of sections at least one of which (a first section) is made a section (formatted in MS-DOS, for example) having a format different from the logical format of a CD-ROM. Publication data is optically recorded in at least one section (a second section) of the sections other than the first section in accordance with the CD-ROM logical format. A CD-ROM utilization tool that utilizes publication data in the CD-ROM logical format and a CD-ROM emulator for converting a request for access to the CD-ROM logical section issued by the CD-ROM utilization tool to a request for access to the optical disk are recorded in the first section.

Abstract: A process for the preparation of a deuterated compound, which requires neither many steps nor an expensive reagent, and is considerably economical and can be widely used for general-purposes because raw materials which can be used therein are not particularly limited. Specifically, a deuterated compound is obtained by a process comprising treating an organic compound (an aliphatic or alicyclic compound, an aromatic hydrocarbon or a polymer compound such as rubbers and proteins) in heavy water under high-temperature and high-pressure conditions not less than the subcritical temperature and the subcritical pressure.
