Title: Electroviscous fluid
Inventor: NAKAMURA TAKASHI
IPC: C10N20/06
Filed: 1990-10-26
Abstract: PURPOSE:To obtain an electroviscous fluid improved in the Winslow effect by dispersing silica particles obtained by substituting water adsorbed on the surfaces of wet silica particles with an organic compound containing a nitrile group in an electrial insulating liquid. CONSTITUTION:An electroviscous fluid is prepared by dispersing in an electrical insulating liquid 0.1-50wt.% silica particles obtained by substituting water adsorbed on the surfaces of wet silica particles with a nitrile compound. The average particle size of the wet silica particles is preferably 10-500mum. As the electrical insulating liquid, a silicone oil is desirable. In particular, diorganopolysiloxane containing a fluoroalkyl group is desirable since it can help the Winslow effect to be manifested more successfully and can prevent sedimentation of the particles due to a difference in specific gravity. Examples of the organic compound include acetonitrile, propionitrile, benzonitrile and alpha-tolunitrile.

Abstract: PURPOSE:To enable a detecting position of a detector to be easily accurately set by a method wherein when a specific exciting phase is excited, a relative position of a driven part and a detection means is so set that the driven part is positioned at a specific position. CONSTITUTION:In a typewriter in which an origin point of a step motor 4 is set as a D-A phase, when one cycle from a A-B phase to the D-A phase is taken as a detection range H, setting positions of a switch 10, i.e., a detector and a projection part 11 are so regulated that when either a B-C phase or a C-D phase within the detection range H is excited, the switch 10 is made to turn ON. Thereby, even through the setting position of the of the switch 10 is slightly shifted during service, since the A-B phase and the D-A phase exist on both sides thereof, timing when the switch 10 turns ON comes difficult to be outside the detection range. Therefore, even though the setting position of the switch 10 is shifted, only when timing of turning ON exists within detection range H, the origin position of a carriage 1 is determined at a position where the D-A phase of the detection range H was excited.
