Abstract: PURPOSE:To make it possible to reduce circuit systems for providing a waiting time only to the one which corresponds only to the case when a first light- sensing element senses light. CONSTITUTION:A detecting device 201 of a rotational angle of a gear is so designed that a plurality of detecting holes 202a, 202b, 202c and 202d formed in a drive gear 13b are detected by a photodetector 203 for which phototransistors 204a and 204b being first and second light-sensing elements and light-emitting diodes 205a and 205b being light-emitting elements are used. The end face on the circumferential-direction detection position (b) side of the through hole 202a out of the through holes 202a and 202b juxtaposed toward the center of the drive gear 13b is formed nearer onto the detection position (b) side than the through hole 202b so that the through hole 202a is detected earlier by the phototransistor 204a on the occasion when the drive gear 13b rotates from the detection position (b) to a detection position (a).

IPC: C09D9/04
Filed: 1983-03-26
Abstract: PURPOSE:To reduce the hydrophobicity rate and precipitation speed of magnetic powder and improve the dispersibility by a method wherein the surface-treated magnetic powder is transferred into a non-polar solvent layer under the existance of salt. CONSTITUTION:When magnetic powder is subjected to surface-treatment, the magnetic powder is dispersed in a polar solvent such as a hydrophilic solvent or water. 50-200ml of the polar solvent is necessary for 100gr of the magnetic powder. When it is dispersed, a pH control agent is added to the polar solvent, if necessary, to control the pH value of the solvent in accordance with the equipotential point of the magnetic powder. NaOH, KOH, Na3PO4 and the like are used as the pH control agent to charge the powder surface negative and HCl, H2SO4, H3PO4 and the like are used as the pH control agent to charge the powder surface positive. When the magnetic powder is transferred into a non- polar solvent layer, an anion system or a cation system surface active agent composed of salt is applied and the hydrophobicity rate and precipitation speed of the magnetic powder is reduced and the dispersibility is improved.
