Title: Automatic focus controller
Inventor: OIKAWA MASARU
IPC: F16K5/10
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To highly accurately decide a focusing point by turning the respective negative value integrated values of a restored image data group in an AF area to respective AF evaluation values, turning the minimum value of the respective AF evaluation values to the focusing point and turning the one of the maximum point image radius to the focusing point in the case that the plural minimum values are present. SOLUTION: A high frequency component integrator 47 outputs a high frequency component integrated value to a CPU 6 and a negative value integration part 48 outputs the negative value integrated value to the CPU 6. In the CPU 6, the AF evaluation value is calculated based on the inputted high frequency component integrated value and/or negative value integrated value and the minimum value for instance is retrieved. Then, a corresponding focus lens position (target position) is specified with a restoration filter number corresponding to the retrieved minimum value as a focusing point index. The minimum value from the calculated negative value integrated value group is searched, and in the case that there is one minimum value, it is turned to the focusing point.  On the other hand, in the case that they are present for plural, the one of the largest point image radius (filter number) is turned to the focusing point.

IPC: H01J31/15
Filed: 1984-06-04
Abstract: PURPOSE:To prevent disconnection of wiring patterns at the time of soldering for lead terminals by providing a slit to each electrode conductive terminal. CONSTITUTION:The leadout part 6a of wiring pattern 6 formed on an anode substrate 2 corresponding to each electrode and electrode conductive terminal 7 are guided to the outside of vacuum case and a slit 20 is provided to each electrode conductive terminal 7.

Abstract: PURPOSE: To facilitate a return of an exposure scanning means for an original placing plate or the like to a start position in a recording cycle by making stop the original placing plate etc. at a position apart from the start position by a prescribed distance through energizing a clutch for forward movement when the original placing plate etc. return to the start position.  
     CONSTITUTION: An optical scanning system 4 gets near a start position with a backward moving speed faster than forward moving speed, then, when the system arrives at the start position compressing in impact absorbing spring 17, a microswitch MS 1  is turned on. At this time, a clutch for backward movement is deenergized and a clutch for foreward movement is energized, concurrently. As a result, the system 4 begins to move again in the scanning direction, and, when a microswitch MS 2  is turned on, the clutch for foreward movement is deenergized, thus, said system is allowed to stop at a designedly advanced position. By this designedly shifted distance, the clutch for backward movement is energized before starting next recording cycle, and a runway for initiating the movement of the system 4 to go back to the start position is made, thereby, the return of the system to the restart position is made ease.
