显示摘要
A sensor (10) preferably capable of high resolution sensing over a large operating range includes a composite diaphragm (12) containing nanotubes or nanowires (14). The nanotubes or nanowires (14) preferably form a mat that is embedded in insulating material (16, 18), such as high dielectric or insulating thin films. The nanotubes or nanowires (14) may provide the diaphragm (10) with a Young's modulus of greater than about 1000 GPa and a tensile strength of greater than about 100 GPa. The strain in the nanotubes or nanowires (14) may be measured by a change in resistance, voltage, current or capacitance.

PROBLEM TO BE SOLVED: To provide a method of measuring a hardness and an elastic modulus of a thin film capable of measuring accurately the hardness and the elastic modulus of the thin film such as a carbon rigid film formed on a surface of a base material by a CVD method or a PVD method.

SOLUTION: When an indenter is pushed into the thin film formed on the surface of the base material to measure the hardness and the elastic modulus of the thin film based on a pushed-in depth therein, the hardness and the elastic modulus of the thin film is measured while the pushed-in depth of the indenter is specified within a range of 2-50% with respect to a film thickness of the thin film.

显示摘要
1,153,574. Radioactivity counting arrangements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Aug.25, 1966 [Aug.13, 1965; Dec.6, 1965], Nos.34885/65 and 51724/65. Heading G1A. An arrangement for handling pulses from a nuclear particle detector comprises an input capacitor (which may be the detector) across which signal pulses are developed in response to detected particles, a light reponsive semi-conductor connected so as to apply discharging current to the capacitor and a light emitting semi-conductor arranged to illuminate the light responsive semiconductor with a flash of light in response to an energizing signal. Pulses from a solid-state capacitor type of detector 10 due to the incidence of nuclear particles or γ-rays are fed via a capacitor 14 and a gate 15 to an integrator 18. Normally the gate 15 and a switch 17 are both closed so that the input to the gate is held at a substantially constant potential despite drift in the detector output. When a pulse occurs the discrimator responds to open gate 15 and allow the pulse to pass to integrator 18. The discriminator then sends a signal to a discriminator 12 which samples the output of amplifier 11 and energizes a GaAs diode 23 to produce a propotionate amount of light. Some of this light is received by a photo-diode 22 which sends a corresponding pulse of current to the detector 10 just sufficient to discharge it. At the same time the pulse shaper 13 is inhibited by a signal from discriminator 19 so that the gate 15 is not opened in response to the discharge pulse from detector 10.
