摘要:
The invention relates to a cellulose solution manufacturing method including: performing an ozonation treatment to bring a cellulose-containing material and ozone into contact with each other; and performing an alkali treatment to bring the obtained treated material and an alkali aqueous solution into contact with each other, thereby dissolving at least cellulose in the cellulose-containing material brought into contact with the ozone in the alkali aqueous solution. According to the invention, it is possible to provide a method of manufacturing a cellulose solution in which cellulose can be dissolved in a more simple manner, a method of manufacturing a cellulose precipitate in which cellulose can be recovered from the cellulose solution, and a method of saccharifying cellulose which uses the cellulose precipitate.

摘要:
In a compound AC generator having at least one pair of magnetic poles, series field windings wound on the magnetic poles, respectively, and at least one shunt field winding wound on at least one of the pair of magnetic poles in layers with the series field winding wound thereon, the series field winding wound in layers with the shunt field winding is associated with means for blocking the current flow through the series field winding in a direction to increase the magnetic fluxes through the associated magnetic pole thereby to minimize the effects of pulsating field current through the shunt field winding and to stabilize the output of the generator.
