Title: Digital camera
Inventor: YOKONUMA NORIKAZU
IPC: H04N9/73
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To obtain a digital camera capable of detecting the possibility of a difference between illuminating light used for photographing and illuminating light obtained when a white balance(WB) is set up. SOLUTION: In the case of setting up a WB control value in a manual mode, a CPU 21 measures the luminance of an object whose WB is calculated by a photometer 38 and stores the calculated WB in a memory 30 together with a date on which the WB is calculated. The luminance of the object photographed is measured by the photometer 38 and compared with the luminance read out from the memory 30, and at the time of judging that a difference between both values is less than prescribed, the WB is accessed from the memory 30. At the time of judging that the difference between the both is more than prescribed, a WB is set up by an automatic mode. A WB control circuit applies WB control based on the WB to an object image being photographed.

Title: Mechanism for z axis fine adjustment for microscope
Inventor: KIKUCHI HIDEKAZU
IPC: G02B21/26
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To prevent a fine adjustment Z stage from being adversely affected even though a microscope is heavy and badly balanced, must be always adjusted, by attaching the fine adjustment Z stage to a lower part on the eyepiece side of the microscope, finely driving an objective lens moving mechanism part up and down, and making the central part void so that light can pass through. SOLUTION: An actuator 2 is arranged in parallel with the stroke direction of the stage, that is, in the Z axis direction, the displacement of the actuator 2 is enlarged and converted in a direction reverse to the displacement direction of the actuator 2 by 180 deg. from revolving motion to linear motion by a displacement enlarging mechanism having elastic hinges 5 to 11, by which fiction and backlash can be ignored while making the displacement of the actuator 2 the fulcrum of a lever. The stroke in the Z axis direction, that is, a perpendicular direction, can be obtained, and an optical axis part, that is, the central part, is made void. Thus, the stage can be set between the microscope main body and the objective lens moving mechanism part, so that the function of the fine adjustment Z stage for autofocusing can be obtained by moving the objective lens up and down.
