Abstract: A sound muffling and heat-discharging case for a computer storage apparatus includes a casing having an opened upper portion and receiving the storage apparatus therein, a cover having a severed side portion partially exposing the peripheral parts of the storage apparatus and serving as a heat discharging portion and covering an upper portion of the casing, and noise-absorbing member being provided along an inner periphery of each of the casing and the cover and absorbing a noise from the storage apparatus. The sound muffling and heat-discharging case effectively decreases noise and heat occurring from a hard disk drive while simplifying the case structure of and thereby facilitating its fabrication.

Abstract: The present invention relates to a novel 1,3-diphenylpropane derivative having an inhibitory activity against tyrosinase represented by the following formula (I): ##STR1## in which - - represents double or single bond,R.sub.1 represents hydrogen or C.sub.1 -C.sub.10 alkyl,R.sub.2 represents C.sub.1 -C.sub.5 alkyl or C.sub.1 -C.sub.5 alkoxyalkyl, orR.sub.1 and R.sub.2 together represent a 5 to 6 membered heterocycle which can be substituted by C.sub.1 -C.sub.5 alkyl and which contains oxygen as the hetero atom,R.sub.3 represents hydrogen or C.sub.1 -C.sub.7 alkyl,R.sub.4 represents hydrogen, hydroxy, or oxo, andR.sub.5 and R.sub.6 mindependently of one another represent hydrogen or C.sub.1 -C.sub.5 alkyl.
