Abstract: A clock oscillator, a clock oscillator production method and use method, and a chip including the clock oscillator are provided. The clock oscillator includes a resonator, a shock-absorbing material layer, and a base, and at least a part of the shock-absorbing material layer is located between the resonator and the base. In the clock oscillator, the shock-absorbing material layer is added between the resonator and the base, and the shock-absorbing material layer can effectively prevent a mechanical wave from being conducted between the base and the resonator, so that the resonator is protected from external vibration. This can ensure, when there is external vibration, that an output frequency of the resonator is not deteriorated and improve shock absorption performance of the clock oscillator.

Abstract: A method for regulating an unmanned aerial vehicle (UAV) includes receiving a UAV identifier and one or more types of contextual information broadcasted by the UAV. The UAV identifier uniquely identifies the UAV from other UAVs. The one or more types of contextual information includes at least geographical information of the UAV. The method further includes authenticating, via an authentication device, an identity of the UAV based on the UAV identifier to determine whether the UAV is authorized for operation, and transmitting a signal to a remote device in response to determining whether the UAV is authorized for operation.

Abstract: A “modified” meta-stable # titanium alloy that, apart from carbon content, corresponds to the composition range for standard Beta-C titanium alloy. The modified alloy comprises vanadium, chromium, molybdenum, zirconium, aluminium, with maxima for oxygen, iron, nitrogen, hydrogen, yttrium, and other elements (apart from carbon and titanium), with a balance (apart from carbon) of titanium. The modified alloy has carbon present at a stable total carbon level sufficiently in excess of 0.05 wt. % achieving an improvement in the mechanical properties of UTS, DSS and fatigue strength in threaded regions, relative to standard Beta-C alloy with a specified carbon level below 0.05 wt. %, with a maximum carbon content controlled so as to preclude carbide formation having a detrimental effect on the level of fatigue strength.

The computer implemented method comprises receiving character data input of a first writing system and ensuring the character data input contains normalized characters. A predefined transform is selected based on the character data input of the first writing system and output to a second writing system to transform the normalized characters of the first writing system to character data output of the second writing system, and providing the character data output to a display process.

Abstract: In a hot isostatic pressing (HIP) process, for example for securing blades (5) to a disc (3) to form a blisk (1), the temperature of the powder (6) to be consolidated is raised to a predetermined temperature, which may be the eventual required pressing temperature, before the pressure rise to the pressing pressure is initiated. If the powder is a titanium alloy and the process employs steel tooling pieces, the application of pressure occurs only when the temperature has risen to the extent that the steel is harder than the titanium alloy.

Abstract: A gamma titanium aluminide alloy consisting of 46 at % aluminium, 8 at % tantalum and the balance titanium plus incidental impurities has an alpha transus temperature T? between 1310° C. and 1320° C. The gamma titanium aluminide alloy was heated to a temperature T1=1330° C. and was held at T1=1330° C. for 1 hour or longer. The gamma titanium aluminide alloy was air cooled to ambient temperature to allow the massive transformation to go to completion. The gamma titanium aluminide alloy was heated to a temperature T2=1250° C. to 1290° C. and was held at T2 for 4 hours. The gamma titanium aluminide alloy was air cooled to ambient temperature. The gamma titanium aluminide alloy has a fine duplex microstructure comprising differently orientated alpha plates in a massively transformed gamma matrix. The heat treatment reduces quenching stresses and allows larger castings to be grain refined.

Abstract: A component can be formed by a hot isostatic pressing (HIP) process but it is necessary to reinforce intricate internal structures against collapse and deformation by the hot isostatic pressing process. The present method utilizes a low melting point salt or alloy reinforcement within the structure which can be released when molten through a drain from the internal structure. The reinforcement may be molten as a result of the hot isostatic process or through achieving a temperature with the component which causes the reinforcement to become molten but without damaging the component itself. The remaining parts of the reinforcement may be removed by use of a solvent or simple washing with a corrosive agent to remove any reinforcement debris.
