    摘要： An optical connector includes a connector housing; an optical ferrule that is housed in the connector housing; a coil spring that is housed in the connector housing and impresses the optical ferrule in a forward direction; and a spring pressing portion that is attached to an rear end of the connector housing, has an optical fiber inserting through-hole and a spring reception portion, and receives a reaction force of the coil spring. The spring pressing portion is divided into two half bodies. Since the spring pressing portion is divided into two parts, at the time of assembly of the optical connector, the optical ferrule is attached to the optical fibers and is terminated, and then the optical fibers can be covered with the spring pressing portion. At the time of the terminating operation, since there is no spring pressing portion that causes interference in the operation, it is easy to perform the terminating operation of the optical ferrule.

    摘要翻译： 光连接器包括连接器壳体; 容纳在所述连接器壳体中的光学套圈; 螺旋弹簧，其容纳在所述连接器壳体中并沿着向前的方向印刷所述光学套圈; 并且安装在连接器壳体的后端的弹簧按压部具有光纤插入通孔和弹簧接收部，并且接收螺旋弹簧的反作用力。 弹簧按压部分分成两个半体。 由于弹簧按压部分被分成两部分，所以在组装光连接器时，将光学套圈安装在光纤上并终止，然后用弹簧挤压部分覆盖光纤。 在终止操作时，由于没有弹簧按压部分导致操作中的干扰，因此容易执行光学套圈的终止操作。

    摘要： A temperature-compensated crystal oscillator for surface mounting wherein an IC chip into which is integrated a temperature-compensated device having an oscillating circuit and a temperature sensor, which supplies a compensation voltage to a variable-voltage capacitor element of the oscillating circuit, and which also has IC terminals disposed along two edges comprising at least diagonally opposite corner portions of one main surface that acts as a circuit function surface is affixed with the use of bumps to an inner base surface of a main container that is concave in section, and one edge portion of a crystal piece is affixed to an inner wall step portion of the main container; wherein an active element of the oscillating circuit that acts as a heat source and a temperature sensor of the temperature-compensated device are disposed at diagonally opposite corner regions of the IC chip at the greatest distance apart. In addition, IC terminals for thermal dissipation are provided in a central region of the IC chip. The present invention provides a temperature-compensated oscillator for surface mounting in which the temperature-compensation operation at startup is satisfactory and frequency stability is maintained.
