Patent number: 6190059Abstract: In a camera body section of a camera according to the present invention, a cartridge chamber unit and a spool chamber unit are located on a lower connecting member with a lens barrel unit as a central unit. Furthermore, a driving-force transfer mechanism is located under the lower connecting member. An output of a driving motor located inside the spool chamber is transferred to the lens barrel unit, cartridge chamber unit, and spool chamber unit through a driving-force transfer mechanism by changing the unit receiving the output. In particular, the driven sections of the lens barrel unit and cartridge chamber unit are driven through a worm gear. According to this camera, it requires a minimum change of each unit section to accommodate a specification change and/or a model change. In addition, it is easy to perform partial assembly of every unit.Type: GrantFiled: February 1, 1999Date of Patent: February 20, 2001Assignee: Olympus Optical Co., Ltd.Inventors: Koji Kato, Setsuya Kataoka, Kunio Yokoyama, Tatsuya Suzuki, Keita Takahashi

Patent number: 4569205Abstract: An electric refrigerator is designed to comprise a freezing chamber provided with a gas duct for drawing off a cooling gas from the freezing chamber and refluxing the cooling gas thereto. A main freezing evaporator is provided in the gas duct to freeze foodstuff stored in the freezing chamber by circulating a cooling gas through the freezing chamber and gas duct. The refrigerator also comprises an auxiliary shelf-shaped freezing evaporator for directly freezing the foodstuff placed thereon in all directions. A damper unit involved in the refrigerator mechanically operates a gas circulation valve provided in the gas duct. During the defrosting mode, the freezing evaporators are rendered inoperative, and the main freezing evaporator is heated to remove frost deposited thereon. During this interval, the damper unit causes the gas circulation valve to close the gas duct.Type: GrantFiled: July 24, 1984Date of Patent: February 11, 1986Assignee: Kabushiki Kaisha ToshibaInventors: Kazuo Dempou, Hideo Niida, Kunio Yokoyama
