A corner bracket assembly for use in an associated frame assembly is provided. An n-type semiconductor is formed on the surface of a silicon substrate, and a mask oxide film and a mask nitride film are formed on the surface of the n-type semiconductor. The foods and beverages of the present invention are safe and their inherent flavor has not been impaired; hence, they may be taken in routinely so that the lipase inhibitory action of the high-molecular weight polyphenol fractions will suppress the rise of triglyceride in blood and prevent obesity. At least one second wireless terminal is configured to operate as a cluster member 120 by communicating with an associated cluster head over a local link.
