Filed: 1988-08-22
Abstract: PURPOSE:To obtain the stable result of inspection by deciding a threshold according to the peak brightness of brightness distribution in the case of binarization of image data. CONSTITUTION:An inspected object W to which magnetic powder liquid is stuck is photographed by a television camera C and the image data is transmitted to a picture element division means M1. In the picture element division means M1, image data of one image plane transmitted is divided every fine picture element to obtain a brightness signal of every picture element. In a brightness distribution conversion means M2, the brightness signal of every picture element obtained thus is arranged according to the brightness to obtain the distribution of the number of frequency picture elements of every brightness. Based on the data of the distribution of the number of picture elements of every brightness, the brightness (peak brightness) at which the number of picture elements is maximum is obtained in a peak detection means M3. In a binarization means M4, the threshold brightness is decided from the value of the peak brightness by previously set rule and the image data is binarized based on the threshold.

IPC: G11B5/60
Filed: 1990-08-06
Abstract: PURPOSE:To prevent the generation of damages in a disk and the magnetic head and to lessen a spacing loss by projecting the gap position of magnetic cores from the position of the surfaces of head sliders facing the flexible magnetic disk. CONSTITUTION:Two pieces of the magnetic heads 1 each having a U shape are so set on both sides of the flexible magnetic disk that the sliding surfaces face each other.

Title: Water detecting type flaw detecting agent and its method
Inventor: NAKANO MIKIO
IPC: G01N21/91
Filed: 1994-08-10
Abstract: PURPOSE:To inspect an object to be inspected without contaminating the object nor requiring any drying process after washing the object with water by preparing a water detecting type flaw detecting agent by mixing specific amounts of a white fine inorganic powder and a water-soluble dye with a volatile solvent. CONSTITUTION:A volatile solvent is used for quickly drying a flaw detecting agent after application so that a dried film of white fine inorganic powder through which water can be sucked up by a capillary action can be formed and pentane, methanol, ether, etc., can be used as the solvent. The whiteness of the fine inorganic powder is required to make a colored indication pattern easily seen against a white background and an inorganic matter is used for the fine powder, because, when an organic matter is used, the powder is dyed and no sufficient contrast can be obtained. It is desirable to adjust the grain size of the powder to >=10mum so that water can be sucked out by a capillary action and the mixing ratio of fine powder to 5-60wt.%, because the whiteness becomes lower when the ratio is lower than 5% and the powder cannot be applied easily when the ratio becomes higher than 60%. The water-soluble dye spreads along the fine powder after it dissolves in water and is colored by visible light and is adsorbed to and immobilized on the surface of the powder. The mixing ratio of the dye can be adjusted to 0.05-5wt.%.

Abstract: PURPOSE:To obtain an output picture of which top and reverse is discriminated, by utilizing a sign of either positive or negative in the matrix of a determinant appearing in approximation by affine deformation in each extremely small area, and discriminating whether a top or reverse surface is obtained in every extremely small area. CONSTITUTION:When an input picture is converted, a top/reverse decision is made and on the basis of the decision result, two input pictures 1A and 1B are selected as a top-side and a reverse-side picture respectively to obtain an output picture 2; even when one input picture is used, the reverse side 5 is replaced by proper reverse-side information, e.g. specific color. After this conversion, whether the picture faces up or down is discriminated on the basis of the sign of the determinant of a matrix of coefficients of this picture conversion system. This picture conversion system provides geometric transformation of pictures in every extremely small area of the picture by affine conversion.

Title: Charging method
Inventor: SUZUKI YASUO
IPC: B22D35/00
Filed: 1981-12-23
Abstract: PURPOSE:To supply proper amts. of molten metal in casting molds in a specified time without adjusting timer relays with respect to a change in the rate of tapping by adjusting the next tilting speed of a ladle in such a way as to keep the time between the  time when tapping is detected and the time when the riser metal of the molds is detected within the set time. CONSTITUTION:When a large amt. of molten metal is put into a ladle 32 and is tapped  therefrom by moving a hydraulic cylinder 44 downward first and tilting tapping ports  34, 35 downward, a sensor S1 detects the same. Then, a timer relay (TR) operates to  stop the tilting of the ladle after a set time T1 and to continue the set time T2 as it is. In the normal time, a sensor S2 detects the rise of the molten metal up to the opening in the riser 56 of a casting mold 12 prior to the terminating of the time T2 and  resets the ladle to stop the tapping. When there is no detection of the sensor S2 even  after the completion of the time T2, the TR resets the ladle. The time T1+T2=T4 and  the difference T5 between the detecting times of the sensors S1 and S2 are compared,  and the case at T4<T5 signifies a decrease in charging efficiency. In such a case, the  ladle is reset at the end of the time T4, and the tilting speed is increased by adjusting  the degree of throttling of a throttle valve 84 prior to the next tilting of the ladle.

IPC: H04N5/232
Filed: 1994-09-01
Abstract: PURPOSE: To obtain a sufficient focus evaluation value regardless of reduction of the sampling period in the focus controller used in a recorder or the like. CONSTITUTION: The luminance component of the video signal obtained by picking up the image of an object by an image pickup element 2 through an optical system 1 where a focusing lens 1a is driven by a focus motor 10 is detected by a video signal processing circuit 4, and the focus motor 10 is controlled based on this luminance signal to focus on the object. In this focus controller, the focus evaluation value obtained by integrating the luminance component in an integrating circuit 6 is compared with a preliminarily set comparison value by an operation circuit 7, and the sampling period of the focus evaluation value is changed based on the comparison result of the operation circuit 7. Thus, an influence of flicker is excluded to increase the focusing speed.
