  • Patent number: 6816304
    Abstract: A fixed-high-power-switching microscope including a usual variable power optical system which can be switched to a fixed high power high resolution optical system, as necessary, is provided. The microscope includes a second optical axis for the fixed high power bypassing the variable power optical system. A prism (reflecting element) movable into and out of a first optical axis switches a viewing optical path from the first optical axis for the variable usual power to the second optical axis for the fixed high power, as necessary, providing a clear magnified image at high magnification and high resolution.

  • Patent number: 6636016
    Abstract: A battery pack for use as a backup power supply device for various electronic devices has a rechargeable battery group having a plurality of cylindrical rechargeable batteries connected in series and/or parallel and arranged in horizontal flat arrays as a flat block, and an electronic circuit for controlling charging of the rechargeable battery group. Two heat radiating plates sandwich opposite surfaces of the rechargeable batteries of the rechargeable battery group and are held against circumferential surfaces of the rechargeable batteries. A battery case houses an electronic circuit positioned at an end in the direction of the arrays of the rechargeable batteries and surrounds the rechargeable battery group to accommodate them therein. The battery case supports the heat radiating plates so as to be exposed to the exterior. The battery pack is compact and free of thermal problems with the rechargeable batteries.

  • Patent number: 6563633
    Abstract: A microscope suitable for use together with MRI, and a support stand for the microscope are provided. A microscope 1 is a non-magnet type where any electric motor is not used, and hence does not induce fluctuations of magnetic field having effects on image quality of an MRI 3 by focusing or zooming. Hence, the microscope of the invention is suitable for use together with MRI 13. Since a clutch C is of non-magnet type, a support stand 2 does not induce changes in the surrounding magnetic field environments if the clutch is operated, and hence it is suitable for use, for example, in proximity to the MRI.
