Abstract: PURPOSE:To rapidly and well correct the blur of images without deteriorating imaging performance by providing a main lens system which forms an object image and a lens group, the face on the extreme object side and the face on the extreme image side of which are both concave with the exit pupil of the main lens system, and inclining the lens group relative to the optical axis. CONSTITUTION:The main lens system which forms the object image and the lens part, the face on the extreme object side and the face on the extreme image side of which are both concave with the exit pupil of the main lens system, are provided and the lens group is inclined relative to the optical axis. Namely, the lens group, the face on the extreme object side and the face on the extreme image side of which are both concave with the exit pupil of the main lens system, is inclined relative to the optical axis in place of a parallel plane plate. The displacement quantity of the image on the image plane is, therefore, sufficiently increased even with a slight angle of inclination and as a result, the change in the incident angle on the periphery is decreased as compared with the parallel plane plate and the difference in the correction rate between the central part and peripheral part of the image plane is decreased. The blur of the image when the photographic lens is deviated is rapidly and well corrected in this way without deteriorating the imaging performance.

Abstract: PURPOSE:To control the oscillation frequency of a window signal outputted from digital VFO by correcting the input value of digital VFO from the output of a phase comparison circuit and a period measurement circuit. CONSTITUTION:A synchronous circuit 12 transmits a read data signal RD to a data separation circuit 14, the phase comparison circuit 13-1 and the period measurement circuit 13-2 as a pulse signal DATA having the width of one period of a basic clock.

Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To stably reproduce a clock by dividing a data line at every m bits so as to correspond to a code word, making a minimum run a specified value or above, converting the data line of m bits to a fixed length code of n bits and limiting the number of continuing times of the data line when the minimum run of a channel bit line after code conversion is continued by the number of prescribed times. SOLUTION: The minimum run (d) is made 1 or above. The data that a basic data length is m bits are converted to the fixed length code (1, 7; 2, 3; 1) by a conversion table containing a code limiting that the minimum run (d) of the channel bit line of an RLL (1-7) code is continued by the number of prescribed times. A shift register 11 divides the inputted data to two bits each to output them to a modulation processing part 13 and a delay element 12-1. When the fixed length code (d, k; m, n; l) is defined e.g. the fixed length code (1, 7; 2, 3; 1), the conversion table when a maximum restraint length is made 1 is formed, and a composite characteristic of minimum data detection is enhanced.

IPC: B65D1/12
Filed: 1990-09-17
Abstract: PURPOSE:To prevent the deterioration of physical properties and to enhance corrosion resistance by making the max. value of the count number of photoelectrons of Cu due to XPS analysis (X-ray photoelectron spectral diffraction method) in the chemical forming film formed to at least one surface of a can body twice or less that of the material quality constituting the can body. CONSTITUTION:A chemical forming film enhancing corrosion resistance and film close adhesiveness is provided to at least a part of the outer surface of a can body and Cu mixed with the chemical forming film prevents the densiness thereof and forms an internal battery along with Al of the can body and lowers corrosion resistance. When the count number of photoelectrons of Cu in the chemical forming film is larger than the twice of that of the can body, corrosion resistance is lowered. Therefore, by setting the count number of the photoelectrons to twice or less, corrosion resistance can be enhanced. The chemical forming film can be made thinner and manufacturing cost can be lowered.

Title: Method for detecting edge position of pattern
Inventor: KUROE SHIGERU
IPC: G16H10/60
Filed: 1985-11-02
Abstract: PURPOSE:To obtain the edge position of a pattern with high stability by replacing the differential value used for calculation of the centroid with the positive difference value obtained by subtracting the prescribed threshold value from said differential value when the position of the centroid obtained by means of the differential value of density showing a level larger than the threshold value. CONSTITUTION:The maximum differential value is obtained from the differential value of plural noticed picture elements and the part having a big change of density in a picture of variable densities is coincident with the area near the pattern edge. Thus this area near the pattern edge can be specified. Then the threshold value that decides an objective area where the calculation for centroid is carried out to obtain the edge position from the maximum differential value is obtained automatically. While the differential value used for calculation of centroid is defined as the difference value {d(Xi)-Tt} obtained by subtracting the threshold value from said differential value. Thus the objective area for calculation of centroid is equal to a part 21 or parts 21 and 23. Therefore the differential value XP is replaced with the difference value {d(Xp)-Tt} which is smaller than the original differential value. Thus it is possible to reduce the effect of said differential value on the result of the calculation of centroid.

Abstract: PURPOSE:To obtain a rough surface state which is enough for the scattering effect of light by forming a finely unseen shape which has surface roughness of 1mumRmax as a non-lens surface.
