Polysaccharide is wet pulverized by ejecting a liquid dispersion of polysaccharide from a pair of nozzles under a high pressure of 70 to 250 MPa to form a pair of jets so that the jets collide against each other. The nozzles are oriented to define a collision angle of 95-178&#xb0; and the number of pulverizing cycles is adjusted such that the polysaccharide is pulverized to an average particle length which is equal to or less than &#xbc; of the initial average particle length while undergoing a reduction in degree of polymerization of less than 10%.

Wet pulverizing of polysaccharides

A device for preventing a fixed angle change of a distributor in relation to an engine. The distributor includes a cylindrical portion, through which a rotor shaft is pierced, and a flange formed on the cylindrical portion. The cylindrical portion is rotatably fitted into a fitting hole formed in the engine while the flange is seated on the engine. A fixing block of substantially hexahedron shape having at least one thrusting projection on either side surface is forcedly inserted into an arcuate elongated hole formed in the flange by means of fastening a bolt pierced through a circular hole formed in the fixing block. The thrusting projections intrude into side walls of the elongated hole for preventing movement of the flange in relation to the fixing block which is firmly fixed to the engine by the bolt.
