摘要： A method for measuring mass of a micro- and nano-sized particle. The method includes placing the micro- or nano-sized particle on a resonator having an oscillator and a first and second cantilevered arms with interdigitating finger, energizing the oscillator at a selective frequency thereby causing mechanical vibration in the first and second cantilevered arms, directing a light beam from a light source onto the interdigitating fingers, sensing intensity of light of the reflected diffraction pattern by at least one photodetector positioned about at least one of the modes, varying the frequency by sweeping a range of frequencies and correlating the sensed intensity to mass to thereby determine the mass of the micro- or nano-sized particle.

摘要： Provided is a nanoporous cantilever including a substrate in a shape of a plate, a tip formed at a front end of the substrate, and a nanoporous structure formed on the tip. Due to the nanoporous structure including nanopores and nanochannels formed on the tip, the nanoporous cantilever greatly increases in detection sensitivity for a material to be detected when compared to a cantilever according to a related art, and may obtain a surface-enhanced Raman signal and thus achieve discrimination of a molecule to be detected.

摘要： In a load cell for a weighing machine, the load cell includes a vibrating beam force sensor clamped at its two ends to respective support parts of the load cell, and wherein each end of the sensor is clamped by a bolt having a head which traps the associated end of the sensor against a support part, the bolt having remote from its head a threaded portion engaged with a nut which tensions the bolt, and a portion of non-circular cross section having at least one cross sectional dimension which is greater than that of the threaded portion, the non-circular cross section portion of the bolt having been drawn through a hole in the support part which had a diameter less than said one cross sectional dimension. This reduces the production of forces parallel to the plane in which clamping is required.

摘要： An elastic force reducing balance and dynamometer comprising a primary spring and a secondary spring which are stressed by bending when an input force is exerted. In at least one of the primary and secondary springs, at least one bar is formed which is stressed, at least partially, by torsion. In this manner, the overall creep of the balance and dynamometer is substantially reduced or eliminated.

摘要： A mass and force meter comprising a frame, a load support, a digital evaluation and display device and two electrically-excited, transversely-vibrating, pre-tensioned strings each having one end fixed to the frame. The other ends of the strings are connected to a force distributor, and first and second transmission elements are provided for transmitting to the force distributor a pre-tensioning force and a force which depends on the load to be measured. One end of each of the transmission elements is fixed to the force distributor and the other ends are connected to the respective pre-tensioning and load forces. A guide member having one end connected to the frame and the other end connected to the force distributor acts together with the strings to guide the force distributor in a statically defined manner relative to the frame with respect to the pre-tensioning force and the force established by the load to be measured. Means are further provided for applying to the evaluation display device the resultant frequency variations caused by application of load to the strings thereby permitting measurement and display of the magnitude of the measured load.

摘要： Improved force measuring apparatus of the one- or two-string type, including means for applying to the movable member of the apparatus a corrective force that compensates for non-linearities in the response of the apparatus over the full range of travel of the pan carrier member between the no-load and full-load positions, thereby to produce a linear variation in the resulting oscillation frequency with respect to load. In the one-string embodiment, linearization means are provided for applying to the oscillatory string means a corrective force that varies quadratically with the displacement of the movable member over its full range between the no-load and full-load positions. In the two-string embodiment, decoupling spring means are provided for independently connecting the two strings in opposite senses between the frame and pan carrier members. The aforementioned linearization means and/or temperature compensation means are also provided for improving the operation of the two-string embodiment.
