    • An automatic lapping apparatus for lapping a piezoelectric material has upper and lower lapping plates, and a carrier disposed between the plates, for holding a piezoelectric material so that it is sandwiched between the plates. The carrier is rotatable to lap the piezoelectric material parallel to the lapping surfaces of the plates while supplying a lapping slurry therebetween. The apparatus also includes a sweep oscillator for applying a sweep signal corresponding to the count of a counter, through an AGC amplifier and a resistor to an electrode supported by one of the plates, a comparing circuit for determining whether the quartz crystal wafer is present underneath the electrode based on the level of the sweep signal applied to the electrode, a memory for storing output data from the comparing circuit at an address corresponding to the count, a dip detector for detecting a dip in the signal applied to the electrode and stopping operation of the counter, a frequency detector for reading the frequency from the sweep oscillator when the dip is detected and the presence of the piezoelectric material underneath the electrode is detected, a frequency determining circuit for determining whether the read frequency is a true resonant frequency of the quartz crystal wafer, a frequency comparator for determining that lapping is completed when the true resonant frequency falls within a predetermined target frequency, and an drive unit control circuit for stopping the carrier when the lapping is completed.

    • A liquid atomizer includes a main body and an ampoule holder detachably attached to the main body for holding ampoules in an annular formation. The main body has an atomizing part for atomizing the liquid discharged from outlets of the ampoules. The outlet of each of these ampoules can be disposed proximal to the atomizing part by moving the ampoules around the annular formation. Positioning devices are between the main body and the ampoule holder for positioning the ampoule holder properly with respect to the main body. The ampoule holder holds the ampoules such that each of the ampoules can move between an advanced position and a retracted position. The outlet of each ampoule moves into the atomizing part when the ampoule moves to the advanced position. The ampoule holder is able to undergo a rotary motion with respect to the main body when each of the ampoules is at the retracted position.
    • 液体雾化器包括可拆卸地附接到主体的主体和安瓿保持器,用于将安瓿保持在环形结构中。 主体具有用于雾化从安瓿出口排出的液体的雾化部分。 这些安瓿中的每一个的出口可以通过将安瓿围绕环形结构移动而靠近雾化部分。 定位装置在主体和安瓿座之间,用于相对于主体适当地定位安瓿座。 安瓿座保持安瓿,使得每个安瓿可以在前进位置和缩回位置之间移动。 当安瓿移动到前进位置时,每个安瓿的出口移动到雾化部分。 当每个安瓿处于缩回位置时,安瓿座能够相对于主体进行旋转运动。

    • A nebulizer includes a nebulizer body a relay pipe. The nebulizer body includes a connection portion that has an aerosol lead-out port to lead out aerosol, and the relay pipe includes a connection portion that has an aerosol introduction port to introduce the aerosol. The nebulizer body the relay pipe can take a first connection state in which the relay pipe detachably connected to the nebulizer body and a second connection state in which the relay pipe is connected to the nebulizer body so as to be not able to be detached from the nebulizer body. In the first connection state, the aerosol introduction port and the aerosol lead-out port are communicated with each other. In the second connection state, the aerosol lead-out port is blocked by a blocking portion provided in the relay pipe. Therefore, the nebulizer in which reuse of the nebulizer body or relay pipe is simply prohibited after the usage can be provided by the configuration.
    • 雾化器包括一个喷雾器体,一个中继管。 喷雾器主体包括具有气溶胶引出口以引出气溶胶的连接部分,并且中继管包括具有气溶胶引入口以引入气溶胶的连接部分。 中继管可以采用第一连接状态,其中可拆卸地连接到喷雾器主体的继电器管和第二连接状态,其中继电器管连接到喷雾器主体,从而不能从 雾化器体。 在第一连接状态下,气溶胶引入口和气溶胶引出口彼此连通。 在第二连接状态下,气溶胶引出口被设置在中继管中的阻塞部分阻挡。 因此,可以通过配置来提供在使用之后简单地禁止喷雾器主体或中继管的重用的雾化器。
