Abstract: A current detector and a detection unit are provided. The current detector is connected to at least one of drive current lines of a rotary machine. The detection unit performs an orthogonal detection on a main frequency detected by the current detector, and extracts a magnitude of a sideband wave. Then, a state of the rotary machine is diagnosed from the magnitude of the extracted sideband wave.

Abstract: A water leak sensing system includes: a plurality of sensor terminals including a sensor installed in a pipeline of a water supply network; and a computer that senses a water leak from the pipeline based on detection signal data of the plurality of sensors of the plurality of sensor terminals, and outputs a result. The pipeline is either a first pipeline not covered by a pipe covering member (PE sleeve) or a second pipeline covered by the pipe covering member. The sensor can detect a signal at a first distance from a water leak point when the water leak occurs in the first pipeline, and detect a signal at a second distance, longer than the first distance, from the water leak point when the water leak occurs in the second pipeline.

Abstract: Provided is a device that, on the basis of a measurement result of a current that has a low value and a wide distribution, identifies the composition of biological molecules passing through a nanoparticle path. This biomolecule information analysis device obtains a current value by applying an electrical field to biomolecules passing through a gap between a first electrode and a second electrode, and identifies the structure of the biomolecules by integrating the current value and making a comparison with a reference value (see FIG. 1).

Abstract: A manufacturing method of a MEMS sensor includes a step of, by irradiating a first hole formed in a second layer on a semiconductor substrate with a focused ion beam for a first predetermined time, forming a first sealing film, which seals the first hole, on the first hole, and a step of, by irradiating a second hole formed in the second layer with a focused ion beam for a second predetermined time, forming a second sealing film, which seals the second hole, on the second hole. At this time, each of the first predetermined time and the second predetermined time is a time in which thermal equilibrium of the second layer is maintainable, and the step of forming the first sealing film and the step of forming the second sealing film are performed repeatedly.

Abstract: A wireless endpoint provided in an automatic inspection system includes a sound collection unit that collects sounds produced by an inspection target, an analysis unit that analyzes the collected sound and obtains a degree of difference between the collected sound and a normal sound learned in advance as an analysis result, a wireless communication unit that wirelessly transmits data including the analysis result to a wireless base station, and a power supply unit that supplies power to the above units. The wireless base station manages the data received from the wireless endpoint. In response to a request from a monitoring terminal that monitors the status of the inspection target, the wireless base station transmits the analysis result retrieved from the data to the monitoring terminal. The monitoring terminal performs a process of disclosing a status of the inspection target determined from the analysis result.

Abstract: A monitoring system includes a plurality of sensor terminals installed for a target to be measured, a base station wirelessly communicating with the sensor terminals, and a calculator communicable with the base station. The sensor terminal includes a sensor element which acquires vibration information of a target to be measured, an arithmetic unit which performs an arithmetic operation for data including the vibration information of the sensor element, and a wireless communication unit. The arithmetic unit performs a reduction process for reducing an amount of data of the sensor element. The wireless communication unit transmits data processed by the arithmetic unit to the base station. After the transmitted data is received, the base station transmits it to the calculator. The calculator includes a signal processing unit. The signal processing unit complements the reduction-processed data to acquire vibration information, and averages the vibration information for a predetermined period of time.
