Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To obtain the zoom lens which has high resolving power and is small- sized while having various aberrations such as a chromatic aberration excellently compensated by providing at least one diffraction optical surface in the whole system. SOLUTION: In the lens constitution figure, arrows m1 and m2 indicate typically the movement of a 1st group Gr1 and a 2nd group Gr2 in zooming to a short-focal-length end 'L'. In the lens constitution figure, the surfaces given ri (i=1, 2, 3...) are (i)th surfaces counted from the enlargement side and on-axis surface intervals given di (i=1, 2, 3...) are (i)th on-axis interval counted from the enlargement side. The surface having ri given '*' is an aspherical surface and the surface having ri given '(HOE)' is an aspherical surface. Thus, the lens system consists of two negative and positive zoom groups in order from the enlargement side and one group or respective groups are equipped with diffraction optical surface (HOE).  Consequently, while the number of lens elements is decreased, various aberrations, to begin with the chromatic aberration, are excellently compensated and the lens is made small-sized, low-cost, and high in performance at the same time.

IPC: G11B27/02
Filed: 1991-02-07
Abstract: PURPOSE: To simplify the design of a conversion section and to reduce noise in the method that a scanned value of an input scanning sequence caused by an input frequency is converted into a scanned value of an output scanning sequence caused from an output scanning frequency. CONSTITUTION: A succeeding scanning frequency of an intermediate stage is derived from an input scanning frequency and an output scanning frequency. Scanned values 6-13 of an input scanning sequence 14 shown on a time base 1 are converted into scanned values 6'-12' of a succeeding scanning sequence having a succeeding scanning frequency through 1st conversion. The scanned values 6'-12' of the succeeding scanning sequence are converted into scanned values 16-24 of an output scanning sequence 15. Adaptation is conducted for either of two conversion sets for the scanning frequency and scanning speed conversion having a preset speed is applied to the other of the two conversion sets.  Deviation of the scanning frequency that might be included in the phase error and the succeeding scanning sequence 25 is compensated by delaying the scanned value and conducting switching process caused periodically.

IPC: G06K9/68
Filed: 1994-02-10
Abstract: PURPOSE:To provide the pattern recognition dictionary generating method which eliminates a need of preliminary determination of the number of reference patterns per category and obtains a high discrimination precision. CONSTITUTION:The distance between two sample vectors expressing the features of a recognition object pattern (S22), and the interaction functioning as an attraction in the case of vectors in the same category and functioning as a repulsion in the case of vectors different by categories is calculated based on this detected distance (S23). Each pattern vector is moved by this interaction (S24). This processing is repeated a finite number of times, and two pattern vectors are successively merged into one when the distance between them is shorter than a threshold. The processing is terminated when a prescribed end condition is met (S25).

Title: Measurement of superposition accuracy of mask for integrated circuit
Inventor: TOUSAKA YASUROU
IPC: H01L21/027
Filed: 1981-02-09
Abstract: PURPOSE:To simply obtain the superposition accuracy of a mask for integrated circuit by a method wherein a plurality of test pattern layers are superimposed on a substrate for exposure and the dimension between each printed test pattern is measured. CONSTITUTION:The distance (a) between the first-layer test pattern 311, and the second-layer test pattern 32 and that (b) between the second-layer test pattern 32 and the first-layer test pattern 312 are measured by a microdimension measuring device. If these test patterns 311, 312, 32 are printed in accordance with design, a=b is established because the test pattern 32 is designed to be exactly located  at the middle of the test patterns 311 and 312. On the other hand, if the test pattern 32 is printed by deviating by DELTAl, a=l+DELTAl, b=l-DELTAl are established to form anot equal to b. The DELTAl can be obtained by calculating (a-b)/2. If this way, superposition accuracy can simply be obtained by measuring the dimension between each test pattern.
