    • An active noise controller includes a duct (2) of a stainless steel having the shape of a pipe and provided with an opening (1) at a first end thereof, and a loudspeaker (3)connected to a second end of the duct (2). The duct (2) is disposed with its opening (1) located at a distance not greater than half the wavelength of a sound produced by a sound source (4) from the sound source (4) so as to face the sound source (4). A sound produced by the vibration of the vibrating member (5) of the loudspeaker (3) travels from the second end of the duct (2) through the duct (2) to the first end of the same, and the sound is radiated toward the sound source (4). The sound radiated through the opening (1) has a frequency substantially equal to that of an unnecessary sound included in the sound produced by the sound source (4), an amplitude substantially equal to that of the unnecessary sound and a phase substantially opposite to that of the unnecessary sound. The acoustic power of the unnecessary sound can be reduced by the sound produced by the loudspeaker (3), propagated through the duct (2) and radiated toward the sound source (4). The active noise controller is capable of achieving three-dimensional sound suppression with out being affected by heat and vibrations.
    • 主动噪声控制器包括具有管形并且在其第一端设有开口(1)的不锈钢管道(2)和连接到管道(2)的第二端的扬声器(3) )。 管道(2)设置成其开口(1)位于声源(4)从声源(4)产生的声音的波长的一半以上,以便面对声源(4) )。 由扬声器(3)的振动部件(5)的振动产生的声音从导管(2)的第二端通过导管(2)行进到其第一端,声音向着 声源(4)。 通过开口(1)辐射的声音的频率基本上等于由声源(4)产生的声音中包含的不必要的声音的频率,其幅度基本上等于不需要的声音的幅度, 的不必要的声音。 可以通过由扬声器(3)产生的声音,通过导管(2)传播并向声源(4)辐射而减少不必要声音的声功率。 主动噪声控制器能够受到受热和振动影响的三维声音抑制。

    • A steering device includes an outer column including fastening pieces formed to face each other at both sides, in the width direction, of a slot portion formed at either of a lower side or an upper side of an embracing body portion along an axial direction thereof, a fixed bracket clamping the outer column, a fastener that fastens the outer column and the fixed bracket, an inner column, and a pushing member having an expanding shaft portion. The two fastening pieces of the embracing body portion are connected by the fastener so that the two fastening pieces can be expanded and contracted, and the expanding shaft portion is elastically biased in an axial center direction of the outer column so as to abut on end zones of the slot portion and expand the two fastening pieces.
    • 转向装置包括外柱,该外柱包括形成为沿宽度方向彼此面对的紧固件,所述紧固件形成在沿其轴向方向的包围主体部分的下侧或上侧的槽部中, 夹紧外柱的固定支架,紧固外柱和固定支架的紧固件,内柱和具有扩张轴部分的推动构件。 包围主体部分的两个紧固件通过紧固件连接,使得两个紧固件可以膨胀和收缩,并且扩展轴部分沿外柱的轴向中心方向弹性偏置,以便抵靠端部区域 并扩大两个紧固件。
