Patent number: 5734499Abstract: An interpupillary distance adjusting mechanism for use in a binocular telescope, having a pair of lens-barrels which contain lens optical systems, respectively, and are placed in parallel with each other. The interpupillary distance adjusting mechanism further has first and second guide shafts, which slidably guide the pair of lens-barrels in a direction substantially perpendicular to the direction of the optical axes of the lens optical systems, interpupillary distance adjusting springs for pushing the pair of lens-barrels in a sliding direction, and an interpupillary distance adjusting cam which can adjust an interpupillary distance by sliding the pair of lens-barrels along the guide shafts as the result of undergoing a pushing force from the interpupillary distance adjusting spring, of converting a part of the pushing force in a direction which intersects the sliding direction, and of moving the pair of lens-barrels by pushing the pair of lens-barrels against the first guide.Type: GrantFiled: August 3, 1995Date of Patent: March 31, 1998Assignee: Olympus Optical Co., Ltd.Inventors: Yoshihiro Matsumoto, Fumio Tomikawa

Patent number: 5405595Abstract: A process for the disposal of carbon dioxide in deep sea, which comprises compressing and dehumidifying gaseous carbon dioxide to be disposed of, passing the so compressed carbon dioxide gas through a cold sea water region where a temperature condition enough to liquefy the compressed carbon dioxide gas prevails via a pipe line to effect cooling of the gas by heat exchange with the cold sea water to thereby liquefy the compressed carbon dioxide gas, conducting the liquefied carbon dioxide through an extension of the pipe line to such a depth of sea water, that the specific weight of the liquefied carbon dioxide at such depth is greater than that of the ambient sea water of such depth, and then discharging out the liquefied carbon dioxide into such deep sea.Type: GrantFiled: December 29, 1992Date of Patent: April 11, 1995Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Fumio Tomikawa, Masaki Iijima
