There is provided an information processing apparatus which occupies a small space and which is capable of supplying image information having high definition and high resolution. A patient monitoring system may generate a plurality of autocorrelation sequences from the signal and combine the autocorrelation sequences to generate a combined autocorrelation sequence. After the specified cleaning solution is selected, it then flows through a hose into a spray gun, which disseminates it onto a surface. These baths and methods are useful for providing a planarized layer of copper on a substrate having small apertures. The comparison is then used to control a mix between the outputs of the two processes to produce an output signal. Arranged between the covering frame and flange is a compensating element which, in a position which is determined by the cathode ray tube butting against the covering frame, can be fixed in relation to the covering frame in that the compensating element interacts with an internal-thread-containing guide part of the covering frame.
