摘要:
A finish for acrylic fiber to be processed into carbon fiber includes an ester compound having at least three ester groups in its molecule and a silicone compound, wherein the silicone compound constitutes 10 to 50 weight percent of the whole of the nonvolatile matter of the finish. A method of manufacturing carbon fiber includes the processes of applying the finish for acrylic fiber to be processed into carbon fiber to acrylic fiber to be processed into carbon fiber; oxidative-stabilizing the finish-applied acrylic fiber in an oxidizing atmosphere at 200 to 300 deg. C. to convert the fiber into oxidized fiber; and carbonizing the oxidized fiber in an inert atmosphere at 200 to 3000 deg. C.

摘要:
The invention provides an improved carbon fiber precursor finish which contains (A) the reaction product of a saturated aliphatic dicarboxylic acid and a monoalkyl ester of an alkylene oxide adduct of bisphenol A, to eliminate fluffs on precursors, and fused or broken precursors throughout stabilization and carbonization processes in carbon fiber production, and thus to provide precursors to be processed into quality high-performance carbon fibers.
摘要:
If arc interruption occurs during AC arc welding, a first AC frequency predetermined for normal welding is switched to a second AC frequency higher than the first AC frequency. This allows the arc to be reignited without applying a high frequency high voltage, thereby preventing the damage of the surface of the weld bead or communication failure due to the high frequency high voltage.

The purpose of the present invention is to provide an angular velocity sensor capable of measuring an exact angular velocity, an ink jet head capable of producing an exact amount of ink, and a piezoelectric generating element capable of generating electric power due to positive piezoelectric effect.In the present invention, a piezoelectric film comprising a first electrode, a piezoelectric layer, and a second electrode is used. The first electrode comprises an electrode layer having a (001) orientation. The piezoelectric layer comprises a (NaxBiy)TiO0.5x+1.5y+2—BaTiO3 layer (0.30≦x≦0.46 and 0.51≦y≦0.62) having a (001) orientation.
摘要:
A toner cartridge includes a toner receptacle that houses toner, a plurality of stirring members housed in the toner receptacle, a plurality of gears meshing with each other on outside of the toner receptacle, and a phase display section. The stirring members are arranged next to each other in the toner receptacle and rotate to stir the toner. Each of the stirring members has a scraper that scrapes off the toner adhering to an inner surface of the toner receptacle. The gears rotate to rotate the stirring members in an interlocked manner with each other. The phase display section shows a meshing position of the gears so that the gears mesh with each other at a position where a phase difference along a rotating direction of the stirring members occurs between the scrapers of the stirring members that are next to each other.
摘要:
An information recording medium includes a recording area for an auxiliary signal, and a recording area for a main signal. The auxiliary-signal recording area and the main-signal recording area are successively arranged. The main-signal recording area stores first information, second information, and third information. The first information represents plural tunes. The second information includes playback control information for separating the tunes into groups and implementing playback of the tunes group by group. The third information includes interactive data for permitting an access to the first information of the tunes group by group.
