    摘要: A hydroxystyrene derivative represented by the formula (I): ##STR1## wherein when R.sup.1 and R.sup.2 : phenyl group, benzyl group or phenethyl group, or R.sup.1 : R.sup.5 O- (R.sup.5 : H, a C.sub.1 to C.sub.5 alkyl group or benzyl group) and R.sup.2 : benzyl group or PhSCH.sub.2, R.sup.3 and R.sup.4 are taken together to represent --CONH--CS--S--, ##STR2## (X.sup.1 : H, a halogen, methyl group, ethyl group, R.sup.7 O-- (R.sup.7 : methyl or ethyl group), nitro group, aminosulfonyl group or amino group, m.sup.1 : 1 or 2), pyridyl group, furyl group or thienyl group, n.sup.1 : an integer of 0 to 3); when R.sup.1 and R.sup.2 : phenyl group, benzyl group or phenethyl group, or R.sup.1 : R.sup.5 O-- (R.sup.5 : as defined above) and R.sup.2 : benzyl group, R.sup.3 : cyano group and R.sup.4 : a carbamoyl group, or R.sup.3 and R.sup.4 are taken together to represent --CO--Y--CH.sub.2 CH.sub.2 -- (Y: O or --NH--) or ##STR3## and when R.sup.1 and R.sup.2 : a C.sub.1 to C.sub.3 alkyl group, R.sup.3 and R.sup.4 are taken together to represent ##STR4## (n.sup.1, R.sup.6 : as defined above), or a salt thereof. The hydroxystyrene derivative or a salt thereof is a compound which is useful as an active ingredient of an antiallergic agent, a 5-lipoxygenase inhibiting agent, an antibacterial agent, a tyrosine kinase inhibiting agent, an ultraviolet absorber or a reverse transcriptase inhibiting agent, and also is useful as an intermediate for preparing various organic compounds.

    摘要: A current collecting assembly for a body, such as an electrodepositing drum, mounted to rotate about a shaft (16) includes a current collector removably connected to an end of the shaft (16), a current conductor (12) connected to a current supply conductor (19) and means (13,14) for pressing a contact portion (12a) of the current conductor means (12) against the current collector (11) with a predetermined pressure. The contact portion (12a) is carried by a hollow body (12b) through which water is passed to water cool the contact portion (12a).
