Developmentaistudy of the Deep sea camera and the shallo sea camera

1960年，美国科学家Davis M.owen将两个单独的35 mm弹簧驱动的半自动机器人相机安装在一个带有两个风轮的外壳中。外壳由6060-TB铝合金实心棒加工而成，内径为8.9厘米。两扇窗为玻璃窗，厚3.2厘米，锥体截断；O形圈证实了塞尔斯的存在。为了加工窗户的开口，这个箱子被切成两块，两半稀疏地处理：它们次要地用螺丝和环状密封件连接。在这项研究中，作者希望制作欧文的打字机。但在当地的仪表店制作截形圆锥体是很困难的。然后，作者制作了衍射式针筒。立体声效果使用了两个独立的摄像头外壳。飞行员体重与海底的每一次接触都会同时启动两台相机--随着内部相机马达的每一次完全缠绕，在一系列下降过程中曝光多达36对立体显微镜下的照片。驾驶员配重与磁铁加载底开关配合使用。使用相机和闪光灯ATR RICHO FF70D，和Sunpack 300DX闪光灯单元与国家SLABE单元。

In 1960 two separate 35mm spring-driven,semi-automatic Robot cameras were mounted in one housing with two windors by an Amarican scientist Davis M.owen. The housing was machined from a solid rod of Aluninium alloy 6060-Tb, giving a 8.9cm bore. The two windows are of plaexiaglas, 3.2cm thck treuncated cones ; o-ring proveide the searls. In order to machine the window openings, this case was cutin two, and the two halves handled sparately:they subsrquently joind with a screw thread and oring seal. A later case was handled in one piece.In this study,writer wishes to make owen's type machine. But it diff icult to make the truncated cones at a local instrument shop. Then writer made diffarecnt type amchine. Two separate camera housings were utilized for the stereo effect. Each contact of a pilot weight with the ocean floor actuates the two cameras Simultaneously-exposing up to thirty-six steropscopic pairs of photographs in a serics of lowering with each full winding of the inside camera motors. The pilot weight is used in conjunction with a magnet-loading bottomswitch. Used camera and strobe atr Richo FF70D,and Sunpack300DX strobe unit with a National slabe unit.
