Title: Device and method to initialize information record medium
Inventor: MIYAUCHI YASUSHI
IPC: G11B11/00
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of the irregularity in the reflectivity caused by the irregularity in superimposing beam spots by using the beam spot having two strong peaks in the width direction as the method to increase the width in the direction of the beam advance. SOLUTION: The laser beam emitted from a high output power semiconductor laser 10 having a wavelength of 810 nm (a maximum output power of 1 W) is made into collimated light beams by a collimating lens 11, divided into two beams by a prism 13 and two beam spots 9 are obtained by an objective lens 12. Then, a disk is rotated at a constant speed of 10 m/S (a constant linear velocity) and the spots 9 are irradiated under the control so that focuses are made on a recording film (an irradiated power: 850 mW). At that time, the length of the spots 9 (at the half power point of the peak power) is approximately 50 μm. Moreover, the directions of the major axes of the spots 9 are made approximately orthogonal with respect to the recording track direction.  The distance between two peaks is set to 2 μm and the power strength of the peak, which is advancingly irradiated time wise, is set higher.

Title: Detection optical system for optical disk having focus detecting function
Inventor: HASHIMOTO KIYOBUMI
IPC: G02B13/18
Filed: 1989-03-28
Abstract: PURPOSE:To obtain a focus detecting function executing automatically the focusing of a pick-up to a disk by arranging a positive single lens, in which the optical axes of a pair of surfaces are made coincident with the optical axis and the surface of the other side is inclined, in a luminous flux to a light- receiving part for detection. CONSTITUTION:In the luminous flux to a light-receiving part 3 for detection receiving a reflected light from an optical disk 1, a positive single lens 7 is arranged in which the optical axis of a surface r1 of one side is made coincident with an optical axis 11 and, simultaneously, the surface r2 of the other side is inclined. In such a case, the positive single lens 7 generates an astigmatism necessary for detecting a focus, and simultaneously, it can be made to function as a converging lens by being arranged in parallel beams. Namely, in the configuration, since the surface r1 is not inclined to the optical axis 11, the positioning of the single lens 7 can be facilitated, and the structure of a lens barrel is simplified, as well. Thus, the astigmatism to be practically sufficient is generated, moreover, a comatic aberration on an axis is hardly generated, and the focus detection by the astigmatism method can be automatically attained.

Title: Method for detecting edge defect of hot-rolled sheet steel
Inventor: KUNINAGA MANABU
IPC: G01B11/30
Filed: 1993-04-05
Abstract: PURPOSE:To detect the edge defect of a self-luminous sheet steel by correcting the threshold of the luminance level of the sheet steel by using the luminance level of scattered light existing in a non-luminous section. CONSTITUTION:The image of the luminance level at the edge section of a hot-rolled sheet steel 1 is picked up 3 by dividing the level into 256 gradations by correcting the stop value of a camera in accordance with the luminance level of the steel 1. Then the threshold of the luminance level of the steel 1 is set based on the luminance level obtained in advance from the previously picked up image of a defectless part and the edge section of the steel 1 in Yi line is detected from picture elements X9 exceeding the gradation of the luminance level A by scanning image pickup data. At the time of scanning Y2 line, another threshold C is set by correcting the mean value B of the luminance levels of five picture elements, namely, those X2-X6 on the Y1 line by adding the threshold B to the threshold A from a position which is two-picture elements deviated from the picture element X9 towards the dark part. Thereafter, the position of the picture element X2 is scanned from the dark part side by using the position of the picture element X2 as the scan starting position of the Y2 line in the X direction. When the luminance level of the element X2 is lower than the threshold C, the part X9 is judged as an edge section. When the luminance level of the element X2 is higher than the threshold C, the element X2 indicates a steel part 1. By repeating the above-mentioned operations until the Y256 line and operating 4 recessed amounts, edge crack sections are judged.
