KNO 3  soln. existing at a point lower than pH 4. The content increases to ≥1.8 wt.% if the reaction time is too long or the temp. is too high. Then, the reaction time and reaction temp. need be optimized in accordance with the oxygen content of the raw materials in order to obtain such Si 3 N 4  powder. The Si 3 N 4  powder is usually not subjected to frictional crushing in water and is subjected to frictional crushing in an org. solvent. Otherwise, the oxygen content increases too high.

Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To prevent or reduce a rolling sound by fixing and providing a sintering oilless bearing to a motor frame via an anti-vibration material being placed in a coaxial cylinder shape. SOLUTION: An anti-vibration material 13 is provided between a motor frame 10 and a sintering oilless bearing 5 and consists, for example, of rubber. The anti-vibration material 13 is arranged coaxially at a motor shaft 7 as in the sintering oilless bearing 5.

However, the vibration is promptly absorbed by the anti-vibration material 13, thus rapidly reducing a rolling sound. Furthermore, the same result is obtained not only at a bearing 5 of a load side but also at a bearing 6 of the side of a commutator 3.
