...Subterranean structures are resistant to earthquakes and water leaks but generally vulnerable to fire and smoke. Architects believe they can beat the problem with sophisticated sensor systems to warn of fires and temporary shelters in which the inside air pressure is kept slightly higher than normal to repel smoke...
Thanks to hefty tax breaks that the Government allows for ESOPs, investors who launch a takeover can reduce their borrowing costs if they set aside part of the stock for employees. At the same time, corporations seeking to repel raiders can use an ESOP as a way to put a chunk of the company into relatively friendly hands. "Every corporate treasurer is looking at it," says Paul Mazzilli, a principal at the Morgan Stanley investment firm. In recent months, three major corporations -- J.C. Penney, Ralston Purina and Texaco -- spent a total of $1.75 billion on ESOPs to shore up their...
...coils. Built into the car's undercarriage are six superconducting electromagnets. When one of them passes over an unmagnetized coil, a current -- and an accompanying magnetic field -- is induced in the coil. The magnetic field in the track has the same polarity as the electromagnet and, since like poles repel, the train levitates off the guideway. As the electromagnet moves faster and faster over the coils, the magnetic force becomes more powerful, raising the car to its cruising height of 4 1/2 in. Until the train is moving fast enough to lift off, it rolls on wheels that retract...
...formidable -- at least on paper. By 1990, when a five-year rebuilding program ends, the forces will have 180,000 troops, 1,205 tanks, 163 F-15 fighter planes, 100 antisubmarine warfare planes and 16 submarines. Tokyo will have more frigates than Britain. All that firepower is designed to repel a limited attack before U.S. help arrives. Since such an attack could come only from the Soviet Union, the Japanese forces could serve as a critical line of defense if a conventional U.S.-Soviet conflict spilled over to Asia...
...more than 30 years, doctors have been trying to rally the weakened immune systems of cancer patients to fight the disease. Only recently, however, have therapies been developed that bring some of the body's own most potent weapons to bear in the struggle to repel invaders ranging from cancer to the AIDS virus. Those weapons include antibodies, tumor-killing blood cells and the chemical messengers that regulate them...
