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.

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).

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.

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.

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: 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.
