    • An apparatus disclosed herein includes a shell movably coupled to a base. The shell defines a chamber, and a counterweight is disposed in the chamber. A first spring is coupled to the shell and a first end of the counterweight, and a second spring is coupled to the shell and a second end of the counterweight. The first spring is oriented at a first angle, and the second spring is oriented at a second angle different than the first angle. The example apparatus further includes an actuator coupled to the first spring or the second spring. The actuator is to oscillate the counterweight to enable the shell to provide an acoustic signal.
    • 本文公开的装置包括可移动地联接到基座的壳体。 壳体限定了一个室,并且配重设置在室中。 第一弹簧联接到壳体和配重的第一端,并且第二弹簧联接到壳体和配重的第二端。 第一弹簧以第一角度定向,第二弹簧定向成不同于第一角度的第二角度。 该示例设备还包括联接到第一弹簧或第二弹簧的致动器。 致动器将摆动配重以使外壳能够提供声信号。

    • A first semiconductor light emitting device comprises: a transparent substrate; a light emitting layer; and a roughened region. The transparent substrate has a first major surface and a second major surface, and is translucent to light in a first wavelength band. The light emitting layer is selectively provided in a first portion on the first major surface of the transparent substrate and configured to emit light in the first wavelength band. The roughened region is provided in a second portion different from the first portion on the first major surface. A second semiconductor light emitting device comprises: a transparent substrate; a light emitting layer; a first electrode; and at least one groove. The groove is provided on the second major surface of the transparent substrate and is extending from a first side face to a second side face opposing the first side face of the transparent substrate.

    • A logging tool having a tool body, which can be positioned in a fluid-filled borehole, including a receiver section and a dipole transmitter; wherein the dipole transmitter includes a transducer with a shell having a reaction mass and a motor located therein, the motor operatively connecting the shell and the reaction mass such that only an outer surface of the shell is in contact with the fluid in the borehole. This new type of dipole source for well logging involves shaking all or part (axially) of a dipole tool body to produce a pure, broadband acoustic dipole signal while at the same time coupling as little energy as possible into the tool body. Important variations on this idea include a linear phased array of shaker sources, and active cancellation of tool borne noise.
    • 一种具有工具主体的测井工具,该工具主体可定位在充满流体的钻孔中,包括接收器部分和偶极发射器; 其中所述偶极发射器包括具有壳体的换能器,所述壳体具有反作用物质和位于其中的马达,所述马达可操作地连接所述壳体和所述反作用物质,使得只有所述壳体的外表面与所述钻孔中的流体接触。 这种用于测井的新型偶极子源涉及摇动偶极工具体的全部或部分(轴向),以产生纯的宽带声偶极子信号,同时将尽可能少的能量耦合到工具主体中。 这个想法的重要变化包括振荡器源的线性相控阵列,以及主动消除工具噪声。
