    • The reference position is determined, by using a test piece, for optically detecting the orientation of a component such as a chip for use in placement apparatus such as a chip mounter. Light is emitted from a light source toward a light sensor to cast a shadow of the test piece onto the light sensor. A first position of an end of the shadow when the pick-up device rotates at a first angle, a second position of the other end of the shadow when the pick-up device rotates at a second angle, and a third position of either end of the shadow when the pick-up device rotates at a predetermined third angle, are detected on the light sensor. Accordingly, the positional relationship of the light source, the light sensor, and the pick-up device is determined as a reference position, based on the positional data.
    • 通过使用测试件来确定参考位置,以光学检测诸如芯片安装机等放置装置中的芯片等元件的取向。 光从光源向光传感器发射,将试片的阴影投射到光传感器上。 当拾取装置以第一角度旋转时阴影结束的第一位置,当拾取装置以第二角度旋转时阴影的另一端的第二位置,以及任一端的第三位置 在光传感器上检测到拾取装置以预定的第三角度旋转时的阴影。 因此,基于位置数据,确定光源,光传感器和拾取装置的位置关系作为基准位置。

    • A waterproof protective cover including an identifying portion which is capable of identifying a predetermined position in a chamber for receiving a connection part of electric wires in an insertion direction. The identifying portion is formed outside a side wall of either upper casing member or lower casing member. By taking advantage of the identifying portion, the connection part of electric wires can be positioned at a predetermined position in a chamber defined by the upper and lower casing members. Moreover, the chamber for receiving the connection part of electric wires has no change in a capacity thereof, so that a filling amount of the sealant is not reduced; therefore, sealing performance can be improved.
    • 一种防水保护罩,包括识别部分,其能够识别用于在插入方向上接收电线的连接部分的室中的预定位置。 识别部分形成在上壳体部件或下壳体部件的侧壁的外侧。 通过利用识别部分,电线的连接部分可以位于由上壳体和下壳体部件限定的室中的预定位置处。 此外,用于接收电线的连接部分的室的容量没有变化,使得密封剂的填充量不降低; 因此,可以提高密封性能。

    • A vibration isolating apparatus which damps and absorbs vibrations from a vibration generating portion. A first restricting passage, a second restricting passage and a third restricting passage are formed in a block member. Respective transit resistances of these restricting passages are different. One end portion of the first restricting passage is provided so as to be able to communicate with a main liquid chamber, and another end portion communicates with a sub-liquid chamber. One end portion of the second restricting passage is provided so as to be able to communicate with the main liquid chamber, and another end portion has an open portion. One end portion of the third restricting passage communicates with the sub-liquid chamber, and another end portion communicates with the second restricting passage. A rotor is rotated to a first position at which the main liquid chamber and the sub-liquid chamber communicate via the first restricting passage and to a second position at which the second restricting passage communicates with the main liquid chamber. In accordance with the invention, liquid passes through the first, second and third restricting passages, and moves reciprocally between the main liquid chamber and one of the sub-liquid chamber and the second restricting passage in accordance with frequency of vibration. Accordingly, vibrations of a wide range of frequencies can be absorbed.
