Abstract: A rotor assembly component which is a component of a gas turbine engine is provided with a rotor assembly component body made from a metal, and a hard particle layer including a mass of hard particles and a matrix material, with the hard particles being made from a material harder than a material forming the rotor assembly component body. The matrix material is made solely from the material forming the rotor assembly component body. The hard particle layer is supported directly on a surface of the rotor assembly component body.

Abstract: A touch probe is attached to a main shaft, and the position (Pp1) of a tip with the probe in an on state and the position (Pp2) of the tip with the probe in an off state, when the end of the main shaft is positioned at a prescribed position (Ps1), are optically measured. The dead zone length of the probe is calculated based on the positions (Pp1, Pp2), and the apparent length of the probe is calculated based on the positions (Ps1, Pp2). After the substantive length of the probe has been calculated by adding the dead zone length to the apparent length, the probe derives the actual length of a workpiece, and a tool is then attached to the main shaft, the position (Pt1) of the tip of the tool is optically measured and the actual length of the tool is calculated.

Abstract: A temperature compensated crystal oscillator having a crystal resonator uses a single thermistor and no expensive varactor. The compensation circuit includes, a low temperature compensation circuit consisting of a first fixed capacitor and a first diode in series, a high temperature compensation circuit consisting of a second fixed capacitor and a second diode in series, and an intermediate temperature compensating circuit consisting of a third capacitor having a negative temperature coefficient. All three circuits are in parallel with each other and in series with the crystal resonator of the oscillator. A thermistor is connected to the anodes of both diodes and biasing resistors and connected to the cathode of the second diode whereby a temperature dependent forward bias is applied to the first diode at all temperatures and to the second diode only at the high temperatures.
