摘要： An imaging system is provided and includes an imaging lens and an imaging device such that the maximum diameter of an effective region of a point image covers three or more pixels of light receiving pixels, the point image being projected onto a light receiving surface through the imaging lens from an intended position. A signal processing unit executes restoration processing on first image data output from the imaging device, and the restoration processing is executed to generate second image data equivalent to the first image data output from the imaging device when the resolving power of the imaging lens is higher. The imaging lens has a first lens group having a positive power, and a second lens group having a positive power, in order from the object side.

摘要： A package-type screw compressor includes a low-pressure stage state compressor and a high-pressure stage compressor. Motive power is transmitted from an electric motor to the two compressors via a speed increaser. The discharge gas, compressed and heated to a high temperature by the low-pressure stage compressor, is cooled by an intercooler. The discharge gas, compressed and heated to a high temperature by the high-pressure stage compressor, is cooled by an aftercooler. A casing of the intercooler and that of the aftercooler are formed integrally with a speed increaser casing, reducing the number of component parts. A cooler portion, formed by the intercooler and the aftercooler, is spaced from the speed increaser casing, thereby preventing heat, produced by the compressed air, from being transmitted to the speed increaser casing.
