    摘要： An acoustic structure of seat back in which speaker units are provided in a padding of the seat back. The padding includes: a frontal backrest surface area which is recessed backwardly of the seat back; and securing holes formed in that frontal backrest surface area. An enclosure of each speaker unit, in which each speaker is securely accommodated, is secured in each of the securing holes. A sound-conductive cushion element is juxtaposed on the foregoing recessed frontal backrest surface area of padding so as to lie on a frontal side of each of the speaker units. The sound-conductive cushion element may be of a network structure to not only provide an improved back support touch, but also achieve an improved conductivity of sounds from the speaker units to a user's back portion. Those padding and sound-conductive cushion element are covered with a trim cover assembly.

    摘要： A compound represented by the formula: wherein R1 is a 5- or 6-membered ring; R3 is a hydrogen atom, a lower alkyl group or a lower alkoxy group; R7 and R8 are each a hydrogen atom or a lower alkyl group; Z1 is another 5- or 6-membered aromatic ring; Z2 is a group represented by -Z2a-W1-Z2b- [wherein Z2a and Z2b are each O, S(O)m (wherein m is 0, 1 or 2), an imino group or a bond, and W1 is an alkylene chain]; X is CR (wherein R is a hydrogen atom, a lower alkyl group, a lower alkoxy group, an acyl group, or R and adjacent R4 may form a 5- or 6-membered alicyclic heterocyclic group) or N; R4 is NR5R6 (wherein R5 and R6 are each a hydrogen atom, a hydrocarbon group, a heterocyclic group or an acyl group), or R5 and R6 are bonded to each other to form a heterocyclic group of NR5R6; and R2 is (1) an amino group which may be a quaternary ammonium or oxide, (2) a nitrogen-containing heterocyclic group which may contain a sulfur atom or an oxygen atom as the ring-constituting atom, in which the nitrogen atom may be converted to a quaternary ammonium or an oxide, or the like; or a salt thereof. The compound has excellent CCR5 antagonistic activity and thus is useful as a prophylactic and/or therapeutic medicine for HIV infection into human peripheral blood monocyte, especially for AIDS.
