  • Publication number: 20190326522
    Abstract: An organic semiconductor element functions as a strain sensor, and includes a substrate and an organic semiconductor layer formed on the substrate as a single-crystal thin film of an organic semiconductor that is a polycyclic aromatic compound with four or more rings or a polycyclic compound with four or more rings including one or a plurality of unsaturated five-membered heterocyclic compounds and a plurality of benzene rings. Since the organic semiconductor layer is formed as the single-crystal thin film, an identical crystal structure is obtained regardless of formation technique. Therefore, when the same strain is given, the same carrier mobility is obtained and uniform property is obtained with respect to the strain. Accordingly, it is possible to provide strain sensors having uniform property.

  • Patent number: 10355630
    Abstract: An object of the invention is to correct a variation of a gain of a current sensor without causing an increase in size and a high cost of an inverter control device. An inverter control device according to the invention includes a 3-phase/dq-axis conversion unit which converts the output current detected by a current sensor into a dq-axis current and a gain adjustment unit which adjusts a detection gain of the current sensor for each phase. In a case where a current value of a secondary harmonic component contained in the dq-axis current is equal to or more than a predetermined threshold, the gain adjustment unit corrects the gain of the current sensor such that the current value of the secondary harmonic component becomes less than the threshold.

  • Publication number: 20190191131
    Abstract: A display apparatus includes an image projector and a controller. The image projector emits image projection light that projects an image onto a projection-target surface. The controller controls, in a time division manner, the emission direction of the image projection light emitted by the image projector. The controller performs control to prevent the sum of the area of one or more regions of the projection-target surface, on which the image projection light is projected, from exceeding a predetermined upper limit.

  • Patent number: 9202665
    Abstract: Provided is a charged particle beam apparatus adapted so that even when an additional device is not mounted in the charged particle beam apparatus, the apparatus rapidly removes, by neutralizing, a local charge developed on a region of a sample that has been irradiated with a charged particle beam. After charged particle beam irradiation for measurement of the sample, the apparatus controls a retarding voltage or/and an accelerating voltage at a stage previous to a next measurement, and then neutralizes an electric charge by reducing a difference between a value of the retarding voltage and that of the accelerating voltage to a value smaller than during the currently ongoing measurement. The charged particle beam achieves neutralizing without reducing throughput, since the local charge developed on the region of the sample that has been irradiated with the charged particle beam is removed, even without an additional device mounted in the apparatus.
