PROBLEM TO BE SOLVED: To provide an electric brake mechanism for an aircraft where a normal line system and an emergency line system are reduced in risks of common mode failures. SOLUTION: The electric brake mechanism includes a brake control unit having several electromechanical brake actuators (EBAs) for generating brake set values in response to a brake command in a normal mode, a plurality of electromechanical actuator controllers (EMACs) fed with AC power, and the electromechanical actuator controllers include at least one inverter for supplying power to the EBA in response to the brake set value, at least one emergency brake power supply and control unit (EBPCU) fed only with DC power, and the emergency brake power supply and control unit include at least one inverter for supplying power to the several EBAs in response to the brake command, and a protecting means for transmitting to the actuator the power supplied by the EMACs or EBPCU while preventing the flow of power in the mechanism.

Abstract:
PROBLEM TO BE SOLVED: To minimize wear of a friction element of a braking device of an aircraft. SOLUTION: This aircraft includes a landing device having each of wheels mounted with a friction brake and an auxiliary brake capable of dissipating energy by a means except friction. When braking is required, whether or not the aircraft is in a braking state for which the friction brake is not indispensable is determined to provide necessary braking by testing a braking parameter. The auxiliary brake is preferentially operated as long as the aircraft remains in the braking state. Only when the aircraft deviates from the braking state, necessary braking is executed by operating the friction brake. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a method and apparatus for densifying a porous product with improvement of densification of the porous substrate by using a film boiling process, in particular, to provide a method and apparatus permitting more complete densification of a substrate (i.e., densification closer to the surface of the substrate). SOLUTION: The method permits more complete densification of a substrate (preform) 110 by selectively providing a barrier 100 that reduces cooling of the surface of the substrate 110 being densified caused by contact with the relatively cool boiling liquid precursor of the densifying material, such as carbon. In particular, the contact between the substrate 110 and the liquid precursor is reduced by utilizing a structure forming an insulator gas layer between one or two physical barriers (such as a mesh material) 100 or the substrate 110 with the liquid precursor (such as a plate spaced apart from the surface of the porous substrate). The barrier 100 is moved into optional position before the applied power level increases sharply near the end of the film boiling densification process. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To improve the safety of a maintenance operator performing work regarding an actuator, and to reduce a loss in an inverter. SOLUTION: The power distribution architecture for distributing power to electromechanical actuators (105, 106, 108; 205, 206, 208; 109A, 109B, 209A, 209B) of the aircraft includes at least one of power distribution elements (150, 250, 160, 260) for distributing power to the electromechanical actuators connected to the architecture, and the architecture receives power from at least one of power distribution buses (PW1, PW2) of the aircraft. A DC network 500 in which a voltage is variably controlled is inserted between the power distribution bus of the aircraft and the power distribution element. COPYRIGHT: (C)2010,JPO&INPIT
