Title: Frequency synthesizer
Inventor: FUKAZAWA TSUNEO
IPC: H03L7/18
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To provide a frequency synthesizer which can flexibly and safely follow a sudden temperature change or the extreme switching of the oscillation frequency and also can prevent an unlocked state by preparing a means which corrects the fluctuation of the oscillation frequency that is caused by the variance of an operating environment. SOLUTION: When the oscillation frequency of a voltage control oscillator 83a has a large change due to a sudden change of the operating temperature or the power voltage, the instantaneous value of an error signal extremely and suddenly varies. In such a case, a differential amplifier 41 calculates the difference between the instantaneous value and the reference voltage Vf to produce a correction signal. The correction signal is given to the oscillator 83a via an adder amplifier 42. Then the oscillator 83a quickly varies the oscillation frequency according to the control voltage that is given as the instantaneous value of the correction signal. Thus, the error voltage that is caused by the output of an LPF 82 according to the oscillation frequency is fast converged to the small value in response to the change of the oscillation frequency.

Filed: 1981-09-12
Abstract: PURPOSE:To make it possible to use a conversion lens even in an autofocus camera, by arranging a D prism consisting of a transparent resin in front of a light receiving window of the range finding part of the auto-focus camera. CONSTITUTION:When a conversion lens 5 is mounted on an auto-focus camera 1, the resultant focal length (f) of the whole of the lens system becomes the  product of the focal length (f) of a camera lens 2 and the magnification of  the lens 5, and the focal length (f) is changed, and the extension of the lens 2  is changed also. A D prism 6 consisting of a transparent resin is arranged  in front of a light receiving window 3 of the range finding part. In the light  incident through the prims 6, the angle of incidence is shifted in comparison with the case where the prism 6 is absent. The angle of the prism 6 is set to a  value corresponding to the change of the extension of the photographic lens system. Thus, even if the conversion lens is mounted, photography is performed  with a proper extension due to the range finding mechanism of the camera.
