摘要:
A solid electrolytic capacitor is obtained in which a sintered metal serves as an anode and a silver layer serves as a cathode. A surface of sintered metal made of tantalum or the like and having an open porosity ratio of more than 75% is oxidized so that an oxide film made of tantalum pentoxide or the like is deposited thereon. Cavities of the metal are filled with an electrically conductive material. Then, the metal is wound around a lead wire and made into a desired shape and size. The silver layer is formed on this porous metal body. Because a specific surface area of the sintered metal is large, a large capacity is obtained.
摘要:
A solid electrolytic capacitor having a lowered leakage current characteristic and an improved ESR characteristic; which has been implemented by decreasing the defects contained in the dielectric film of the anode body. It includes a valve metal foil which makes anode and a sintered layer provided on the upper and lower surfaces of the valve metal foil, which sintered layer covering the entire surface of side faces of valve metal foil in three directions with exception of the anode lead portion. A flat plane area of valve metal foil, which makes anode, covered with sintered layer is not less than one half of the flat plane area of sintered layer.

A manufacturing system has an inspection data collecting apparatus that is capable of carrying out, upon receipt of a signal containing measurement data in different formats according to the type of inspection or a measuring instrument, processing in accordance with the signal and the format of data to create data in a certain format, and of transmitting a signal for giving an instruction to the measuring instrument in association with the format compatible with the measuring instrument. All data obtained by the inspections in all steps for manufacturing a product is accumulated as inspection data and exchanged among the steps.

The present invention provides a lens inspection apparatus and an inspection sheet that make is possible to easily evaluate the resolution of a lens at low cost. A lens inspection apparatus can include an inspection sheet having a test pattern, a sliding holding portion for holding the inspection sheet, a light source for introducing a light beam into the test pattern of the inspection sheet held by the sliding holding portion, a rotary holding portion for holding the sliding holding portion so that the sliding holding portion can rotate in a plane, and a measuring section for capturing an image projected on a screen through the inspection sheet and a projection lens to be inspected, and subjecting the image to image processing. The test pattern has a measuring region in which linear light-shielding portions are arranged in stripes so as to achieve a predetermined spatial frequency. By rotating the rotary holding portion, the resolution of the test pattern, in which the light-shielding portions extend in different directions, can be easily evaluated. Accordingly, the invention makes it possible to simply evaluate the lens resolution at a low cost.
