  • Publication number: 20210031935
    Abstract: [Object] To provide a supersonic aircraft and a method of reducing sonic booms, by which sonic booms due to engine exhaust can be reduced. [Solving Means] A supersonic aircraft includes: a pair of engine nacelles 12R, 12L mounted on a fuselage 11 of an airframe 10; fins 13R, 13L as a pair of shielding plates that inhibits engine exhaust 15 discharged from jet engines (not shown) accommodated in the engine nacelles 12R, 12L from wrapping downward around the airframe 10; and a pair of horizontal tails 14R, 14L disposed behind the engine nacelles 12R, 12L. The fins 13R, 13L are disposed on the horizontal tails 14R, 14L so as to sandwich the engine exhaust 15, respectively.

  • Patent number: 10670094
    Abstract: A brake lining includes friction structures, back boards fastened to respective the friction structures, a base plate supporting the friction structures. Each of the friction structures includes two adjacent friction portions with a groove formed in the front surface in between, and a thin portion with a smaller thickness than thicknesses of the friction portions, the thin portion located in a position corresponding to the groove. Each of the friction structures is supported by the base plate on two support points located in the two friction portions respectively. The thin portion has a constant length, the length being equal to a maximum width of the friction portions and satisfying a condition that L/D is equal to or greater than 1.1, where D denotes the length of the thin portion and L denotes a distance between the two support points located in the friction portions.

  • Publication number: 20190095256
    Abstract: The present invention extends to methods, systems, and computer program products for controlling runtime access to application programming interfaces Embodiments of the invention allow library developers to more precisely and easily control which of their libraries' APIs can be called dynamically. Thus, their servicing and versioning burden can be more appropriately controlled. Further, application developers can control which such APIs to further exclude from dynamic calling scenarios, to minimize the runtime support overhead (e.g., preventing generation of metadata).

  • Patent number: 9979384
    Abstract: A timing adjustment method for a drive circuit, including: a rise detector for a rise start when a voltage-driven semiconductor element is turned off; a timing signal output unit outputting a speed change timing signal after a set delay time has elapsed from the rise start; and a conduction controller for a conduction control terminal of the semiconductor element using the timing signal, comprises: defining an estimated terminal voltage of the conduction control terminal when a rise completion time elapses; increasing a delay time by a predetermined unit time, and changing the drive signal to a turning off level again, when the conduction control terminal doesn't fall below the estimated terminal voltage after the drive signal is changed to a turning off level before the level is inverted; and determining a delay time, when the conduction control terminal falls below the estimated terminal voltage initially, as a set value.

  • Patent number: 9900000
    Abstract: A drive device for controlling a power switching element to turn on and off includes: an on-side circuit performing an on operation of the power switching element; an off-side circuit performing an off operation of the power switching element; and a temperature detector detecting a temperature. At least one of the on-side and off-side circuits includes a current path for supplying or drawing a gate current of the power switching element and a switch circuit for switching the gate current. The switch circuit transitionally changes the gate current based on the temperature of the power switching element when the switching circuit switches the gate current.

  • Patent number: 9836290
    Abstract: Support for dynamic behavior is provided during static compilation while reducing reliance on JIT compilation and large runtimes. A mapping is created between metadata and native code runtime artifacts, such as between type definition metadata and a runtime type description, or between method definition metadata, a runtime type description, and a native code method location, or field definition metadata, a runtime type description, and a field location. A mapping between runtime artifacts may also be created. Some compilation results include trampoline code to support a reflection invocation of an artifact in the reduced runtime support environment, for virtual method calls, call-time bounds checking, calling convention conversion, or compiler-intrinsic methods. Some results support runtime diagnostics by including certain metadata even when full dynamic behavior is not supported.

    Abstract: A semiconductor device, in which a plurality of control terminals that correspond to a main terminal and the same semiconductor chip protrude from a surface of an encapsulating part, and a plurality of signal paths that include the plurality of control terminals are positioned so as to be aligned with the main terminal in a first direction. Provided in each of the plurality of signal paths are pairs of relay members having identical functions, and a first relay grouping that includes one relay member of the pair of relay and a second relay grouping that includes the other relay member of the pair are positioned neighboring each other aligned in the first direction, with the ordering of the first relay grouping being mirror-inverted relative to the second relay grouping.

  • Patent number: 9584877
    Abstract: One or more identifiers that facilitate efficient native image validation can be generated and stored in an auxiliary file upon pre-compiling of an assembly. The native image can be validated against an assembly from which the native image is generated, among other files that influence the generated contents of the native image, based upon the auxiliary file and included identifiers. Additionally, native image validation can be performed in an increasing cost sequence associated with each identifier included within the auxiliary file.
