Title: Device and method for measuring micro-fibrous cellulose
Inventor: SHIGEMATSU MASAHITO
IPC: G01N11/00
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To enable the simple evaluation of the proportion of extremely short fibers which is important for evaluating the function of micro-fibrous cellulose by using a Canadian freeness measuring device provided with mesh wire gauze and a side tube and detecting the amount of outflow from the side tube by a predetermined wt.% concentration of slurry. SOLUTION: Slurry in a filter tube 1 is flowed down through a screening plate 5, and the amount of a liquid that flows out from the side tube 15 of a measuring funnel 11 is accurately measured by a graduated measuring cylinder 18 as a detecting mean to evaluate freeness. Then wire gauze with such mesh as to allow the passage of micro fibers and to block the passage of average-size fibers, preferably approximately 80-100 mesh, as the screening plate (filter) 5 is arranged at the bottom part of the filter tube 1 according to the level of fineness of micro-fibrous cellulose. Furthermore, the level of fineness of micro-fibrous cellulose is determined by an evaluating/determining means on the basis of a detected value at the time of supplying a predetermined amount of slurry of a concentration of 0.05-0.15 wt.%.  It becomes possible to measure the proportion of especially extremely short fibers simply, speedily, and precisely.

Abstract: PURPOSE:To miniaturize a stepping motor by a method wherein a group having the phase difference of 0 deg. and 180 deg. and another group having the component of phase difference except 0 deg. and 180 deg. are arranged so as to be separated in a magnetic circuit and necessary number of windings of a stator coil is wound concentrically around the magnetic pole of one side of stator poles while the stator poles, having no coil, are removed. CONSTITUTION:A stator yoke, connecting a stator pole 12a to the stator pole 12b, is provided with a sufficiently large sectional area so that the magnetic reluctance of the same becomes small enough whereby flux, generated in a stator coil, arrives at the stator pole 12b. On the other hand, the sectional area of the stator yoke, connecting the stator pole 12a to the stator pole 12d, is provided with the minimum sectional area so that the magnetic reluctance of the same becomes high enough whereby it makes hard that the flux, generated in the stator coil, arrives at the stator pole 12d. Accordingly, coils around the stator pole 12b as well as the stator pole 12d become unnecessary. According to this method, the necessary number of winding of the stator coil is wound concentrically around one side of the pair of poles and the stator poles having no coil are removed whereby the title motor may be miniaturized.
