    • A loudspeaker apparatus 1 includes a loudspeaker unit 3 and an installation device 2. The loudspeaker unit 3 includes drivers 22 and 23 and an enclosure for the drivers composed of front and rear members 20 and 21. The loudspeaker unit is detachably mounted to an installation device 2, which, in turn, is secured to an installation surface 11 to which the loudspeaker apparatus is to be installed. The loudspeaker unit is mounted rotatable about its center axis 25. The drivers have respective sound radiation center axes 22a and 23a, which are oriented to intersect the center line 25 at a predetermined angle &thgr;. Thus, the direction in which the drivers radiate sound can be changed by rotating the loudspeaker unit about the center axis.
    • 扬声器装置1包括扬声器单元3和安装装置2.扬声器单元3包括驱动器22和23以及用于由前部和后部构件20和21组成的驱动器的外壳。扬声器单元可拆卸地安装到安装设备 2,其又被固定到要安装扬声器装置的安装表面11。 扬声器单元可围绕其中心轴线25旋转安装。驱动器具有各自的声辐射中心轴线22a和23a,它们以预定角度θ定向成与中心线25相交。 因此,可以通过围绕中心轴旋转扬声器单元来改变驾驶员辐射声音的方向。

    • A one-pack coating composition is disclosed. The composition comprises (A) an oligomer or polymer containing an acid anhydride group, a blocked hydroxyl group and an epoxy group as indispensable functional groups in the same or different molecules, (B) a heat-potential curing catalyst which comprises a complex of an organometallic compound and an electron-donating compound or an onium salt and which exhibits its activity upon heating, (C) an ultraviolet absorber comprising a triazine or oxalic anilide, and (D) a hindered amine light stabilizer having a piperidine ring of the following structure: wherein R represents R1—CO—, a C2 to C20 alkyl group or R1—O— (R1 being a C2 to C20 alkyl group), and R2, R3, R4 and R5 independently from each other represent a C1 to C3 alkyl group, or a phenolic antioxidant. A method for coating using this coating composition is also disclosed.
