Disclosed herein are benzylidene compounds represented by the formula (I): ##STR1## wherein A represents ##STR2## (wherein B represents hydrogen atom or an acetyl group, W represents hydrogen atom or --CH.sub.2 --CH.sub.2 --CO--O--R, X.sup.1, X.sup.2 and X.sup.3 represent independently hydrogen atom, a hydroxyl group or a methoxyl group (two or three of them may be the same or all of them may be different), Y represents oxygen atom or imino group (--NH--), Z represents a methyl group or a phenyl group, and R represents a straight chain alkyl group having 1 to 18 carbon atoms, or branched or cyclic alkyl group having 3 to 18 carbon atoms, provided that when A is ##STR3## R is not an alkyl group having 1 to 2 carbon atoms, and when A is ##STR4## and X.sup.1, X.sup.2 and X.sup.3 are hydrogen atom, R is not an alkyl group having 1 to 2 carbon atoms), a cosmetic composition containing the same and an ultraviolet absorber comprising the same.
摘要:
To provide a glass substrate storage case capable of preventing quality deterioration of a glass substrate, a glass substrate transfer apparatus automatically transferring a glass substrate from the glass substrate storage case to another case; a glass substrate management apparatus managing glass substrates individually, a glass substrate distribution method for trading a glass substrate while storing the glass substrate in a specialized glass substrate storage case, a sealing member improving a sealing effect, and a sealing structure using the sealing member.The glass substrate storage case includes: a bottom member 12 on which a reticle R is placed; a cover member 20 overlaid on the bottom member 12 so as to cover the reticle R placed on the bottom member 12 and to form a space portion between the cover member 20 and the bottom member 12; a sealing member 18 provided in the bottom member 12 and/or the cover member 20 to keep the space portion airtight in a state where the cover member 20 is overlaid on the bottom member 12; and hook members 24 provided on the cover member 20 and hooked to the bottom member 12 to maintain the state where the cover member 20 is overlaid on the bottom member 12.

摘要:
A device for supporting a wafer comprises a base plate for arranging the wafer thereabove and a plurality of supports circumferentially arranged on the base plate to support the peripheral of the wafer. In order to expose portions of the wafer covered by the supports, either an annular member to engage with the supports for moving them radially outward, or a roller driven by a motor to rotate the wafer relative to the supports is provided.
