Title: Radioscopic apparatus
Inventor: FUJII MASAJI
IPC: G01N23/18
Filed: 1989-10-24
Abstract: PURPOSE:To detect easily and quickly a defect of a body to be inspected by preparing good-article image data from a plurality of radioscopic images and storing them and by computing differences between these data and radioscopic image data on the body to be inspected. CONSTITUTION:An radioscopic image of a body to be inspected which has fewer detects is displayed on a display 73 and an area of concern wherein the defects are concentrated is set. This area is replaced by a non-defect area corresponding thereto, so as to obtain a good-article image, and the data thereon are stored in a good-article image data storage element 35. Next, X-rays are applied on a body T to be inspected and radioscopic data thereon are inputted to an input image data storage element 33. Then, substraction of the data in the storage elements 35 and 33 is executed by a subtracter 39 and the result is stored in a difference image data storage element 37. Subsequently, an image processor 41 subjects these data to a binary-coding processing and then to processings such as picture area calculation, circularity measurement and filtering, and thus a defect is detected.

Title: Manufacture of aluminum anode foil for low-voltage electrolytic capacitor
Inventor: WATANABE YOSHIAKI
IPC: H01G9/04
Filed: 1992-09-18
Abstract: PURPOSE:To suppress the formation of a hydrate oxidant layer during storage and achieve stabilized high electrostatic characteristics by treating an etching surface with hot water containing a small amount of alkali or alkali silicate before chemical treatment after etching treatment and then by treating with aqueous solution for giving water repellency to a hydrate oxidant formed. CONSTITUTION:For the aluminum(Al) anode foil for low voltage electrolytic capacitor, the aluminum foil is first subjected to AC etching in an electrolyte containing chlorine ion. Thereafter, the first requirement is to wash the etching surface and remove residual chlorine ion, and then the surface is treated with hot water containing a small amount of alkali or alkali silicate before the chemical conversion treatment. Hydrated oxide is formed on the etching surface after the hot water treatment. The second requirement is treated by an aqueous solution for giving water repellency to the hydrated oxide. Formation of the hydrated oxide layer can be greatly restricted by these two requirements, so that decrease in electrostatic capacity can be prevented and dielectric loss can be reduced without hardly clogging fine etch pits due to etching treatment.

As a result, when it is detected that a state where both data are matched is shifted to that where they are not matched, clocking is initiated accordingly. On the other hand, when it is detected that a state where both data are not matched to that where they are matched, clocking is automatically completed accordingly, and a required time during this period is clocked by a clocking part 6. Then, the required time being clocked by the clocking part 6 is stored in the RAM 9 as a required time for moving between the setting points.
