    摘要: A process is provided that involves reductive coupling of polysilane precursors to form polysilane in the presence of ultrasonification. The resulting precursors, upon pyrolysis, lead to improved SiC ceramic product. Ultrasonification can be used to produce oligosilanes from precursors thereof, or polysilanes from monomers, dimers, trimers, or oligomers. Precursors can include Si:C in a ratio of about 1:1, and the invention allows formation of SiC having a Si:C ratio of about 1:1.

    摘要: An object of the present invention is to provide a linear actuator in which reliability is improved, and performance is also easily improved. The present invention provides a linear actuator including a stator, a movable element having an iron member, and being reciprocatable with respect to the stator, a permanent magnet fixed to the stator so as to be opposed to the iron member, and a coil fixed to the stator. Because both the coil and the permanent magnet are fixed to the stator, electrical current does not have to be supplied to the movable element, and the feeder lines connected to the coil will not be broken due to the movement of the movable element. In addition, the weight of the movable element will not be increased even when the weigh of the permanent magnet is increased in order to obtain high magnetic flux density for improvement in performance. Moreover, because the movable element does not include a magnet, a magnetizing operation does not have to be applied to the movable element. The permanent magnets may be a pair in which the directions the magnetic poles thereof differ from each other, and two pairs of permanent magnets may be provided. The number of magnetic fluxes that run through the magnetic pole elements and the iron member can be increased by providing a magnetic reluctance section around the permanent magnets.
