    • A noise deduction for a rotorcraft includes a unit to produce compressed air, a drive shaft provided with a first air supply passage in which the compressed air from the air-producing unit flows, and rotor blades provided with second air supply passages in which the air from the first air supply passage flows. In order to eject the compressed air supplied from the rotor blades, ejection nozzles having an ejection adjusting mechanism therein are arranged at respective blade tips of the rotor blades and respective trailing edges thereof in the rotational direction. In operation, the ejection nozzles eject the compressed air to the radial direction of the rotor blades, so that, since the blade tip vortex in the vicinity of the blade tip of the preceding rotor blade is relocated outside the blade tip of the following rotor blade, a direct collision thereof on the vortex can be avoided.
    • 用于旋翼航空器的噪音扣除包括产生压缩空气的单元,设置有第一空气供应通道的驱动轴,来自空气产生单元的压缩空气流过该驱动轴;以及设置有第二供气通道的转子叶片,其中空气 从第一个供气通道流出。 为了喷射从转子叶片供应的压缩空气,其中具有喷射调节机构的喷射喷嘴设置在转子叶片的各个叶片尖端及其相应的后沿沿旋转方向。 在操作中,喷射喷嘴将压缩空气喷射到转子叶片的径向方向,使得由于在前一转子叶片的叶片尖端附近的叶片尖端涡流被重新定位在随后的转子叶片的叶片尖端的外侧 可以避免其在涡流上的直接碰撞。

    • For suspending a sliding door from a pair of parallel spaced overhead tracks, there is provided a dual-roller support comprising first and second separate sections each comprising a roller and its mount. Only the first section is directly affixed to the top edge of the door. Thus, for installation of the door, the roller of the first section is first manipulated into rolling engagement with one of the overhead tracks thereby temporarily suspending the door therefrom. The second section is then bolted to the first section, with the roller of the second section in rolling engagement with the other overhead track.

    • A covering member (4), a solar battery (3) and a hand-operating mechanism-containing movement (2) are housed inside a case (1) which has a front side opening (1a), a glass (5) which is provided in the front side opening (1a), in the order of these constituents from the face side of the case (1). The solar battery (3) is disposed opposite to the glass (5) at a light receiving surface thereof which is covered with the covering member (4). The covering member (4) can also serve as a dial. If the covering member (4) is molded out of ceramic, it can provide the dial with a white appearance, so that light can sufficiently be transmitted to the receiving surface of the solar battery (3) owing to the light transmittance of the ceramic.
