摘要： A dual mode warhead is provided for use against both soft and hard targetsnd capable of sensing which type of target has been struck comprising a casing made of a ductile material containing an explosive charge and a fuze assembly. The ductile warhead casing will mushroom and later split upon striking a hard target while still confining the explosive. Proper ductility and confinement are necessary for fuze sensing. The fuze assembly contains a pair of parallel firing trains, one initiated only by high and one by low impact deceleration. The firing train actuated by low impact deceleration contains a pyrotechnic delay to allow penetration of soft targets.

摘要： A data recording disk file of the liquid-bearing type has an improved head-disk interface provided by a transducer carrier with new properties. The carrier supports a conventional head for reading and writing data to the disk. The carrier has an air-bearing surface near its front end, a ski pad near its rear end, and a plurality of ski feet or struts which support the air-bearing surface off the liquid film of the disk when the disk file is not operating. The air-bearing surface is in the form of a pair of air-bearing rails located forward and outboard of the rear ski pad so that no air-bearing effect occurs in the rearward region of the carrier to assure the skiing action of the rear ski pad. The struts are separated from the air-bearing rails to not interfere with their air-bearing performance and support the rails away from the liquid film on the disk. In one embodiment there are at least three struts arranged on the carrier so that both the air-bearing rails and the ski pad are supported off the liquid film when the disk file is not operating. As operational speed is approached the air-bearing effect causes the front end of the carrier to rotate about the two rear struts, thus raising the forward strut(s) and the air-bearing rails off the disk and lowering the rear ski pad into contact with the liquid film.

摘要： A unique method for recording, reading and erasing data bits in a data storage device is described. Using extended scanning tunneling microscopy (STM) techniques, a tunneling electron current by resistive heating selectively melts discrete areas of a state-transformable film; then heat is dissipated rapidly, writing data bits by changing the film in said areas from a first state to a second state wherein an electronic property, such as conductance, work function or band gap, in said areas is changed.Again, using extended STM techniques, the effect of this changed electronic property of said film on the tunneling current is measured for reading the written data bits. Minimizing the effect of blemishes on the material is effected, during operation in STM constant current mode by measuring dI/dV or dI/ds, and during operation in STM variable current (constant gap) mode by measuring (dI/dV)/I or (dI/ds)/I.Also by using extended STM techniques, data bits can be selectively erased by resistance heating the film to a temperature higher than the crystallization temperature for a sufficient period of time, restoring selected discrete areas to said first state and each affected electronic property substantially to its original condition.

摘要： A shaped charge and method of breaching reinforced masonary walls is disced. The shaped charge includes an annular liner located centrally between the ends of a cylindrical container filled with explosive. The device is placed in a pilot hole in the wall and is detonated simultaneously at the ends. The charge creates an annular radially expanding jet of explosive gases and fragments directed into the wall providing a man size opening therein.
