An MgB-based superconducting wire for a liquid hydrogen fluid level sensor which can maintain an unimmersed portion of the MgB-based superconducting wire for a liquid hydrogen fluid level sensor in a non-superconducting state even without heating the unimmersed portion is provided. A wire for a liquid hydrogen fluid level sensor comprises an MgB-based superconductor which contains Mg, B, and Al. The critical temperature at which the electrical resistance becomes essentially zero is 20-25 K, and the transition width, which is the difference between the temperature at which the electrical resistance begins to decrease toward zero and the critical temperature, is at most 5 K.

A wire saw which has excellent cutting ability and which is not easily clogged by chips formed by cutting is provided. It has a bodyhaving a first metal wirewhich is made of a cobalt-based alloy, two second metal wiresandwhich are made of a cobalt-based alloy, and three third metal wires-which are made of a cobalt-based alloy and are wound on the first metal wire. The second metal wiresandare helically wound on each of the third metal wires-in opposite directions so as to cross each other. Cutting teeth are constituted by projectionswhich are formed by the crossing points of the two second metal wiresand

A content supply apparatus is interposed between a portable terminal and a content server, to obtain content demanded by the portable terminal and transmit the obtained content to the portable terminal. A content holding section holds content obtained from the content server. A content supply section obtains the demanded content from the content holding section if the demanded content is there, or from the content server, and transmits the demanded content to the portable terminal. In a preferred embodiment, the content supply section transmits the content in divided content units of a maximum information amount that can be displayed by the portable terminal. In another embodiment, a prefetching section prefetches other content, referred from the transmitted divided content units, and stores the prefetched content in the content holding section.
