Abstract: The invention provides a water-soluble metal working lubricant which is suitably employed particularly in press-working of aluminum material and which is excellent in both working properties and degreasing properties. The water-soluble metal working lubricant includes 85 mass % or less of water (A); 5 to 75 mass % of a metal salt of an organic carboxylic acid (B) wherein carboxylic acid residue has 8 or more carbon atoms in total and the acid/alkali ratio by mole is 1:0.5 to 1.1; 1 to 50 mass % of at least one metal salt (C) selected from among an organic phosphate ester metal salt, an organic phosphite ester metal salt, an organic phosphonate metal salt, and an organic borate ester metal salt, each having an alkyl group having 8 or more carbon atoms in total; and 10 to 80 mass % of a non-ionic surfactant (D).

Abstract: Disclosed is a diesel fuel composition obtained by mixing a diesel oil and a biodiesel oil, which can be used in popular diesel cars. The diesel fuel composition enables remarkable reduction in sludge formation. Specifically disclosed is a diesel fuel composition obtained by mixing a diesel oil containing an aromatic component and a biodiesel oil. The diesel fuel composition is characterized in that the biodiesel oil content in the diesel fuel composition is 10-50% by volume, and the aromatic component content in the diesel oil is not less than 30% by volume.

Abstract: Provided is a method for producing a hydrogen-containing gas, especially hydrogen for a fuel cell, by reforming a C5 or more hydrocarbon or oxygen-containing hydrocarbon that is liquid at ordinary temperature and pressure. This is a method for producing a hydrogen-containing gas, which comprises reforming a hydrocarbon or an oxygen-containing hydrocarbon having at least 5 carbon atoms and liquid at ordinary temperature and pressure, with a catalyst that contains Ni, Mg and Al and contains at least one noble metal element selected from Pt, Pd, Ir, Rh and Ru.

Abstract: An antifreeze/coolant composition, comprising a) a base material such as water, alcohol, glycol and glycol ether; b) a fluorine compound and c) an inorganic acid.

Abstract: In an information distribution/reproduction control apparatus, a plurality of stream servers distribute real-time reproducible stream information to a plurality of clients through a network like the Internet. A transit control server controls the stream servers for the distribution of the stream information, and also controls the clients for real-time reproduction of the stream information.

The water-soluble metal working lubricant includes 85 mass % or less of water (A); 5 to 75 mass % of a metal salt of an organic carboxylic acid (B) wherein carboxylic acid residue has 8 or more carbon atoms in-total and the acid/alkali ratio by mole is 1:0.5 to 1.1; 1 to 50 mass % of at least one metal salt (C) selected from among an organic phosphate ester metal salt, an organic phosphite ester metal salt, an organic phosphonate metal salt, and an organic borate ester metal salt, each having an alkyl group having 8 or more carbon atoms in total; and 10 to 80 mass % of a non-ionic surfactant (D).

Abstract: An information management system records in a server contents that need not be updated for a fixed time-period. The system accesses desired contents in a local device or the server storing the contents. A request for information is made from an information browsing unit to a local request relaying unit which receives the request and analyzes the request contents. The local request relaying unit acquires a server-side control file managed by the server to which the request is directed and also acquires a local-side control file from a duplicate information storing unit. Confirmation is made as to whether the latest version of the requested information exists in the duplicate information storing unit. If the latest version of the requested information exists in the duplicate information storing unit, the requested information is fetched from the duplicate information storing unit; otherwise the information is fetched from the server computer.

Abstract: In an information distribution control system, a sync control server adds a time stamp to the stream information JS capable of being reproduced in real time and adds the sync time information to the storage-type information JT, so that the stream information JS and the storage-type information JT are reproduced in temporal synchronism with each other based on the time stamp and the sync time information in a plurality of clients.

Abstract: Pieces of information having different attributes are informed to a recipient. An information receiving apparatus includes receiving channel control units for respectively receiving pieces of article information respectively allocated to a plurality of transmission channels and having different attributes in units of channels, a display, and display control unit for displaying the pieces of article information respectively received by the receiving channel control units on the display.

Abstract: An information distribution apparatus generates streaming packets, that contain information which can be reproduced in real time, to be distributed to a plurality of receiving apparatuses. A distribution control unit inquires the receiving apparatuses, before starting the distribution, to decide whether they would like to accept the streaming packets. An accumulation control unit receives the replies from the receiving apparatuses and accumulates the number of replies. The distribution control unit starts or stops the distribution of the information on the basis of the number of replies accumulated in the accumulation control unit.

Abstract: Contents on a server that need not be updated for a fixed period of time are recorded directly in a medium, and desired contents in a local device can be accessed by the same operation procedure as that for accessing the server storing the contents. When a request to acquire delivery information is made from information browsing unit with respect to a local proxy server, the local proxy server analyzes the request, and acquires a server-side control file managed by a server with respect to which 10 the request has been made, and a local-side control file in duplicate information storing unit. If corresponding information exists in the duplicate information storing means and also if the information has the latest version number, the information is fetched from the duplicate information storing unit; otherwise the delivery information is fetched from a server computer.

Abstract: A glycol-based coolant composition which provides an excellent metal corrosion inhibition despite its low phosphorus content is disclosed. The glycol-based coolant composition contains: (A) 0.1-5.0% by weight of at least one ingredient selected from group A′ consisting of C6-C12 aliphatic dibasic acids and their alkali metal salts; (B) 0.1-10% by weight of at least one ingredient selected from group B′ consisting of alkyl benzoic acids and their alkali metal salts; (C) 0.001-0.1% by weight of at least one ingredient selected from group C′ consisting of strontium compounds and their alkali metal salts; and (D) 0.1-0.3% by weight of at least one ingredient selected from group D′ consisting of phosphoric acids and their alkali metal salts.

When a request to acquire delivery information is made from information browsing unit with respect to a local proxy server, the local proxy server analyzes the request, and acquires a server-side control file managed by a server with respect to which the request has been made, and a local-side control file in duplicate information storing unit. If corresponding information exists in the duplicate information storing means and also if the information has the latest version number, the information is fetched from the duplicate information storing unit; otherwise the delivery information is fetched from a server computer.
