An optical compensatory sheet comprises a cellulose ester film, an orientation layer and an optically anisotropic layer formed of liquid crystal molecules in this order. Alignment of the liquid crystal molecules is fixed. An alkaline solution is coated on a surface of the cellulose ester film to saponify the surface. The saponified surface is coated with a coating solution of the orientation layer.

An optical compensatory sheet comprises a cellulose acetate film. The film contains 100 weight parts of cellulose acetate having an acetic acid content of 59.0 to 61.5% and 0.01 to 20 weight parts of an aromatic compound having at least two aromatic rings. The cellulose acetate film has an Re retardation value measured at 550 nm (Re550) in the range of 0 to 200 nm and an Rth retardation value measured at 550 nm (Rth550) in the range of 70 to 400 nm. The cellulose acetate film further has a thickness in the range of 10 to 70 &#x3bc;m. The optical compensatory sheet is used in a liquid crystal display.

An emulsification and dispersion method of a hydrophobic, photographically useful compound comprising dispersing a water-insoluble phase containing the hydrophobic, photographically useful compound in water or in a hydrophilic colloid composition, wherein the water-insoluble phase at a temperature at which the prepared dispersion is stored may have a viscosity of from 100 poise or more to less than 1,000,000 poise at the shear rate of 10 sec.sup.-1. According to the present invention, a silver halide photographic material comprising a fine dispersion of a hydrophobic, photographically useful compound and having an excellent production suitability can be obtained.

Emulsification and dispersion method of hydrophobic, photographically

A silver halide photographic material comprises at least one silver halide emulsion layer provided on a support. The silver halide emulsion layer contains a color coupler. According to the present invention, the color coupler is contained in particles of a specific polymer dispersed in the silver halide emulsion layer. The specific polymer comprises repeating units represented by the formula (I): ##STR1## in which R.sup.1 is hydrogen, a halogen atom or an alkyl group having 1 to 4 carbon atoms; each of R.sup.2 and R.sup.3 is an aliphatic group or an aromatic group, or R.sup.2 and R.sup.3 are combined with the oxygen atoms and the phosphorus atom to form a heterocyclic ring; and L is a divalent linking group selected from --CO--, --O--, --S--, --NR.sup.4 --, --SO.sub.2 --, a divalent aliphatic group, a divalent aromatic group and a combination thereof, and R.sup.4 is hydrogen or an aliphatic group.

Silver halide photographic material comprising emulsion layer containing

A disk-type brushless motor comprises a 2p-pole magnet rotor (p represents an integer of 2 or more) having alternating N and S poles and a single position sensor element. A stator armature having an armature coil is formed on two conductors which contribute to the generation of torques and extend with an opening angle substantially equal to the width of each magnetic pole of the magnet rotor. A projection such as a screw for generating cogging to enable the self-start of the magnet rotor is disposed at a place somewhere short substantially by a width

A disc type brushless motor comprising a rotor provided with a field magnet having two or more poles, and a stator on which loop-like armature windings are flatly positioned opposite to the field magnet in quantity of two or more in the circumferential direction and in two stages or more in the radial direction. The stator is also provided with elements for detecting the poles of the field magnet. The armature windings are positioned so that they do not overlap in either the circumferential or the radial directions of the stator. One terminal of each armature winding is connected to a common line and the other thereof to a semiconductor rectifier. Each pole of the field magnet may consist of a plurality of segments in the form of a fan-like plate or a square plate.
