It is intended to provide a dry fractionation method for fat whereby the performance for fractionating a fat into a high-melting fraction, a medium-melting fraction and a low-melting fraction can be improved to thereby preventing, in particular, the medium-melting fraction from worsening of the melting properties in the mouth and a decrease in the melting point with the passage of time and, in its turn, improving the melting properties in the mouth of a chocolate product which is produced by using the thus obtained hard butter for chocolates, etc. A method of fractionating a fat wherein a fraction (in particular, a medium-melting fraction) obtained by dry fractionation is efficiently separated from a high-melting fraction and a low-melting fraction mixed therewith. More specifically, a dry fractionation method which comprises heating a crystal fraction containing a large amount of 1,3-disaturated-2-unsaturated triglycerides to thereby melt the 1,3-disaturated-2-unsturated triglyceride components followed by solid/liquid separation of tri-saturated triglycerides as a crystal fraction, thereby achieving a favorable performance of fractionating 1,3-disaturated-2-unsaturated triglycerides and saturated triglycerides.

Liquid crystal compositions which can improve the low .DELTA.n (refractive index anisotropy) of conventional liquid crystal compositions containing a silacyclohexane compound and which retain a low viscosity and hence show no decrease in response speed. Liquid crystal compositions having a high .DELTA.n of 0.13 to 0.25, a low viscosity of 30 cp or less, a low threshold voltage and a high voltage holding ratio can be obtained by adding thereto, as a required component, a compound having both a silacyclohexane ring and a tolan structure, or a miture of a compound having a silacyclohexane ring and a compound having a tolan structure.

A sheet conveying device, which is included in an image forming apparatus and an optional device attachable to the image forming apparatus, includes a sheet container, a sheet feeder, a separator, a guide, and a projection. The sheet container loads multiple sheets. The sheet feeder feeds a sheet out of the multiple sheets in the sheet container. The separator separates the sheet from another sheet fed together with the sheet. The guide having a guide surface to guide the sheet passing the separator such that the sheet is fed in a predetermined sheet conveying direction. An upstream end in the sheet conveying direction of the guide surface of the guide is located lower than a downstream end in the sheet conveying direction of the separator. The projection is disposed facing the separator at the upstream end in the sheet conveying direction of the guide surface.

In the lighting control device according to the exemplary embodiment, the detection section detects the presence or absence of a person in a lighting area and a movement speed of a person, based on an image data of the lighting area that is lighted by a light source of a plurality of lighting apparatuses and is acquired from an imaging device. A decision section decides whether each of division areas is a stay area or a non-stay area based on the movement speed of a person detected by the detection section. A lighting control section performs different lighting controls on the lighting apparatus of the division area decided as the stay area by the decision section and the lighting apparatus of the division area decided as the non-stay area.
