NON-ANNULAR LANDS

摘要

THE PRESENT INVENTION INCREASES REAL ESTATE BY PROVIDING NON-ANNULAR LANDS WHICH DO NOT COMPLETELY ENCIRCLE THE THROUGH HOLES. THE NON-ANNULAR LANDS ARE NON-ANNULAR, THAT IS THEY DO NOT EXTEND 360° AROUND THE THROUGH HOLE. PREFERABLY THE NON-ANNULAR LANDS CONTACT NO MORE THAN ONE SIDE OF THE THROUGH HOLES THEREBY PROVIDING REAL ESTATE NOT OTHERWISE AVAILABLE USING CONVENTIONAL LANDS. THE PRESENT INVENTION ALSO RELATES TO A METHOD FOR PRODUCING SUCH NON-ANNULAR LANDS.
