Title: Focus detection device of optical pickup, or the like
Inventor: EMOTO MASAMI
IPC: G02B7/28
Filed: 1982-05-19
Abstract: PURPOSE:To prevent detection error without increasing the sperture degree of a cylindrical lens, by arranging two cylindrical optical system lenses for generating the astigmatism so that their buses cross orthogonal to each other. CONSTITUTION:Instead of a condenser lens and cylindrical lens of conventional optical system, two cylindrical lenses 10 and 11 having the same focal length are arranged so that their buses cross orthogonal to each other. As a result, each of the cylindrical lenses acts in a face including an optical axis and buses of lenses, and a detected difference signal becomes the one shown in the figure so that an error signal is prevented from being detected that shows as if a recording surface and an objective lens are getting closer although they are actually getting away. Since incident light keeps to be parallel in the acting surface of the convergence effect of the cylindrical lens so that a convergent luminous flux is not made to be incident, it is not necessary to widen the aperture angle of outgoing light.

Title: Texture meter for paper
Inventor: ISOZAKI KENJI
IPC: G01B11/06
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To calculate the strength distribution for each flock size regardless of fluctuation in the paper making speed without requiring any intricate operation by employing a plurality diaphragms of different diameter on the projecting side and providing a signal processing circuit for operating the texture from the magnitude of variation of signal for each diameter of diaphragm on the projecting side. SOLUTION: Four diaphragms 20 are arranged in a row on the light projecting side in the order of diameter such that a diaphragm of largest diameter is arranged on the most upstream side in the direction of paper flow. Four diaphragms 30 corresponding to the diaphragms 20 are arranged in a row on the light receiving side. A texture signal means a variation of texture when it is observed in the field of view of the inside diameter of the projecting side diaphragm 20. In case of a fine texture, variation is significant at a part associated with the projecting side diaphragm having a small bore diameter and the texture signal is increased on the side of small bore diameter. In case of a rough texture, the texture signal is increased on the side of large bore diameter. Consequently, the signal can be utilized for texture management during paper making. Since the inside diameter of the projecting side diaphragm 20 is fixed, variation of paper making speed is not effected.

Abstract: PURPOSE:To materialize a scanning type charged particle beam device for readily preventing the rotation of an image when the intensity of a magnetic type convergent lens is changed. CONSTITUTION:A signal memorized in a first frame memory 11 is read to supply to a second frame memory 12 for memory.
