Abstract: PROBLEM TO BE SOLVED: To provide a method of identifying the aerial position of a flying object allowing a highly precise identification of the aerial position of the flying object. SOLUTION: Pulse laser beams are applied from a flying object 1 in the air to plural reflecting bodies 2 and 3 disposed at plural positions on the ground 4 with a known distance L0 between them, and the ground is scanned with the pulse laser beams at least in the direction crossing the direction of progress of the flying object 1. The positions form which strongest reflected light returns by the scanning are recognized as the positions of the reflecting bodies 2 and 3, and the distances L1 and L2 from the flying object to the reflecting bodies 2 and 2 are operated based on the periods of time till the pulse laser beams reflected on the reflecting bodies 2 and 3 return. Then, based on the operated distances L1 and L2 and the distance L0, the air position of the flying object 1 is identified according to the principle of triangulation.

Title: Operating method of cooling tower and cooling tower
Inventor: KOMIYA JUJIRO
IPC: F28C1/12
Filed: 2001-02-22
Abstract: PROBLEM TO BE SOLVED: To ensure an outdoor air flow rate per unit area of a filler corresponding to the quantity of water being sprayed to the filler in the spray region even if the region of filler being sprayed is limited by reducing the spray region of an upper water tank, and to stabilize the cooling capacity even at an unusable wet-bulb temperature lower than the ice point when the filler is entirely sprayed with water. SOLUTION: Immediately before sprayed water shows a trend of freezing under a state where the sprayed water stands only in recessed parts on the surface of a filling plate through surface tension and the contact area with outdoor air flow is decreased, water is sprayed only to the central region of the filling plate in order to increase the thickness of a water film and louver blades 18 at the left and right outdoor air inlets 16 and 17 are fully closed.
