Title: Focus correction device of automatic focusing camera
Inventor: SATO SHIGEMASA
IPC: G02B7/36
Filed: 1992-01-29
Abstract: PURPOSE:To reduce the cost required for adjustment and make a lens unit compact by finding the movement quantity of a focusing lens group from a stored value and the movement quantity of an image formation point per unit movement quantity of the focusing lens group. CONSTITUTION:A 1st storage means 1 is stored with the quantity DELTABf of deviation of the image formation point from a film plane (quantity of deviation at wide-angle end or telephoto end) due to variance in lens assembly, lens component size, or refractive index among lens materials. An arithmetic means 1 calculates the correction movement quantity of a focusing point lens group from the value stored in the 1st storage means and the movement quantity of the image formation point per unit movement quantity of the focusing lens group. A lens driving means 5 drives the focusing lens group according to the final movement quantity obtained by adding the correction movement quantity of the focusing lens group found by the arithmetic to the movement quantity of the focusing lens group calculated from a focusing value obtained by a non- TTL type range finding means. Consequently, the deviation of the image formation point from the film plane which is caused at the time of the manufacture and assembly of components is easily corrected.

Abstract: PURPOSE:To prevent the occurrence of vibration or progressive waves causing chattering and suppress the occurrence of chattering by giving a groove or mass to a rotor regular ring or a contact spring thereby providing a difference in natural vibration frequency, in a bar-shaped ultrasonic motor. CONSTITUTION:In the structure of the rotor regular ring 2 and the contact spring 2a of a rotor, which pressure-contacts with the vibrator of a bar-shaped ultrasonic motor, are constituted integrally, a groove 5 is made in opposition to the topside of the rotor regular ring 2. Hereby, for sin mode the groove 5 lies the loop position of vibration, and the rigidity of mode drops, and the natural vibration frequency fall greatly, but for cos mode, the groove 5 lies in the node position, so the drop of the natural vibration frequency becomes relatively small. As a result, a difference occurs in both natural vibration frequencies, and the occurrence of chattering can be prevented.

Abstract: PURPOSE: To use optically directional elements as the screen for a pair of stereoscopic image observation by continuously rotating the optical device around an axis and stereoscopically producing a pair of images matched with the pair of visual field of an object. CONSTITUTION: An optical device is made rotative around a rotational axis 4. The optical axis of an objective lens 1 is extended with an angle θ/2, for example, with respect to the axis 4. A reflection plane 2 takes an angle so that the main beam directed to a lens 3 becomes parallel to the axis 4. If a distance 'F' between the optical equipment and the eyes of the observer, who is positioned at an position 'E', is made one half of the distance between standard pupils, the right eye views the image of the object at a surface 'A' looking from the right side of the object. If the optical equipment rotates 180 deg. around the axis 4 while the observer and the object are standing still, the left eye sees the image of the object at the surface 'A' looking from the left side of the object.  Thus, the left and right eyes observe the enlarged image of the object from the left and right sides of the object. Note that the image rotates around the axis 4 at a high speed. Thus, the observer obtains a complete stereoscopic image of the object.
