  • Patent number: 7573662
    Abstract: A movement preventing structure for a color separation prism prevents or reduces the movement in an optical axis direction of the color separation prism caused by the thermal expansion or contraction of a color separation prism supporting member.
    Type: Grant

  • Patent number: 7119967
    Abstract: When the adjusting shaft is rotated, the rotation of the adjusting shaft is transmitted to the rotationally movable barrel. The rotationally movable barrel rotates so that the rotationally movable barrel moves forward and backward along optical axis while rotating due to the interaction between the female screw portion formed in the distal end of the rotationally movable barrel and the male screw portion formed in the second flange portion of the fixed barrel. The forward and backward movement of the rotationally movable barrel along optical axis causes the rectilinearly movable barrel connected to the connecting portion of the rotationally movable barrel through the groove, to move forward and backward along optical axis. Accordingly, the CCD fixed to the rectilinearly movable barrel through the CCD carrier moves forward and backward along optical axis, thereby correcting the flange-back length.

  • Patent number: 7063129
    Abstract: A heat transport device has an evaporator and a condenser connected through a vapor phase channel and a liquid phase channel and has wicks of the condenser arranged symmetrically around an axis orthogonal to the direction of gravity. The flow of fluid in a liquid phase inside the wicks is not disrupted even when the heat transport device is tilted at any angle relative to the horizontal surface or the vertical surface.

  • Patent number: 5332031
    Abstract: A cooling system for cooling heat-producing electronic devices, such as CCDs, included in an electronic apparatus, such as a television camera, comprises electronic cooling devices disposed near the heat-producing electronic devices, buffering heat conducting mechanisms connecting the heat-producing electronic devices to the electronic cooling devices to transfer heat by conduction from the heat-producing electronic devices to the electronic cooling devices, a motor-driven fan disposed in an air passage formed by dividing the interior of the body of the electronic apparatus by a partition wall, and a heat radiating coil unit is formed by coiling a small tube in loops and sealing a heat conveying fluid in the small tube, such coil unit having heat absorbing portions connected to the electronic cooling devices and a heat radiating portion disposed in the air passage.

  • Patent number: 5306174
    Abstract: A connecting device for detachably connecting two separate casings, includes a first movable engaging member slidable on a first casing, a second stationary engaging member secured to the second casing, and a link assembly operatively connected to the first engaging member. An actuator handle is operatively connected to the link assembly. A stopper is provided for locking a movement of the actuator handle. When the actuator handle is operated in one direction, the first engaging member is moved through the link assembly toward the second engaging member so as to be engaged with the second engaging member. When the actuator handle is operated in the other direction, the first engaging member is moved through the link assembly remote from the second engaging member so as to be disengaged from the second engaging member.
