    • An electromagnetic relay includes a resin case, a coil, a movable contact; a fixed contact, a flat recess, a ventilation hole, a cooling member and a flat passage. The resin case has a housing space therein. The movable contact is within the housing space and is actuated by the coil. The fixed contact is within the housing space. The flat recess is formed at the case to communicate with the housing space. The ventilation hole is formed at the case to provide communication between the recess and an exterior of the case. The cooling member is within the recess to cool flame that passes through the recess. The flat passage is formed between the cooling member and an internal wall surface of the recess and has a clearance dimension such that flame is extinguished.
    • 电磁继电器包括树脂壳体,线圈,可动触点; 固定触点,平坦凹槽,通风孔,冷却构件和平坦通道。 树脂壳体中具有容纳空间。 可动触头位于容纳空间内并被线圈驱动。 固定触点位于收纳空间内。 平坦凹部形成在壳体与壳体空间连通。 通气孔形成在壳体处,以提供凹部和外壳之间的连通。 冷却构件在凹部内,以冷却穿过凹部的火焰。 平坦的通道形成在冷却构件和凹部的内壁表面之间,并且具有使得火焰熄灭的间隙尺寸。

    • A flash device for use in association with a camera is disclosed. The camera provides focal length data representing a focal length of a lens mounted on the camera to the flash device. The flash device comprises a body portion, a flash head pivotally mounted on the body portion, a xenon tube provided in the flash head for emitting a flash light, and a lens is provided in front of the light emitting means movably to change the angle of the cone of the flash light. A driving circuit, controlled by a microcomputer, is provided for driving the lens in response to the focal length data to set the angle of the cone of the flash light correspondingly to the focal length. A pivot detector is provided for detecting the pivotal movement of the flash head. When the pivotal movement is detected, the microcomputer controls the driving circuit so as not to drive the lens but to maintain the lens, during and after the pivotal movement, in the same position as it was before the pivotal movement.
    • 公开了一种与相机相关联使用的闪光装置。 相机提供表示安装在相机上的镜头的焦距到闪光灯设备的焦距数据。 闪光装置包括主体部分,可旋转地安装在主体部分上的闪光头,设置在闪光头中的用于发射闪光的氙灯,并且可透光地设置在发光装置的前方以改变角度 闪光灯的锥体。 由微计算机控制的驱动电路用于响应焦距数据驱动透镜,以根据焦距设定闪光灯的锥角。 提供了用于检测闪光头的枢转运动的枢轴检测器。 当检测到枢转运动时,微型计算机控制驱动电路,以便不驱动透镜,而是在枢转运动期间和之后将透镜保持在与枢转运动之前相同的位置。
