Abstract: Provided is a moisture meter includes a mass scale for measuring a mass of a specimen, a heater for heat the specimen, a processor causes the moisture meter to control the heater to heat the specimen until a change in mass of the specimen becomes not more than a predetermined threshold and calculate a moisture content of the specimen, and a storage unit. The processor causes the moisture meter to execute a measurement of a moisture content a plurality of times by using, as the specimen, a standard substance for inspection having a predetermined theoretical moisture content with an arbitrary mass when being heated at a predetermined temperature, to calculate a standard deviation of a measured moisture content in the measurement executed the plurality of times, and a to evaluate an influence of an installation environment by determining whether the standard deviation is not more than a predetermined value.

Abstract: Provided is a moisture meter including a mass measurement unit for measuring the mass of a specimen, a heater for heating the specimen, a control arithmetic unit configured to control the heating unit to heat the specimen until a change in the mass of the specimen becomes not more than a predetermined threshold and calculate the moisture content of the specimen, a timepiece for measuring a heating time, and a storage unit. The control arithmetic unit measures the moisture content of a standard substance for inspection and a heating time, diagnoses the presence/absence of an abnormality in the heating unit by comparing a measured heating time with a predetermined time as a set heating time stored in the storage unit in advance

Abstract: A tire testing apparatus performs the test by rotating a tire while the tire is in contact with a drum. A plurality of sensors are provided on the outer circumferential surface of the drum and are arranged side by side along a widthwise direction of the drum, thereby measuring the ground contact forces at the ground contact position with the tire. A calculation unit obtains, based on the ground contact forces measured by the sensors, a displacement amount Dy of the ground contact position in the widthwise direction and a change amount ΔFy of the ground contact force Fy in the widthwise direction which corresponds to the displacement amount Dy, thereby calculating the lateral stiffness sharing rate Ky rib on the basis of the displacement amount Dy and the change amount ΔFy.

Abstract: Provided is an electronic balance that enables a user to recognize the magnitude of disturbances in real time. An electronic balance (1) whose natural frequency is known, includes a load measurement mechanism (4) configured to detect weighing data (Zn), and an arithmetic processing unit (8) configured to perform arithmetic processing by using the weighing data (Zn), wherein the arithmetic processing unit (8) extracts a vibration component (Fr) of the natural frequency from the weighing data (Zn) detected by the load measurement mechanism (4) and displays the vibration component (Fr) of the natural frequency. By using the vibration component (Fr) of the natural frequency as an index of disturbances, it becomes possible to recognize in real time the magnitude of the disturbances during weighing.

Abstract: To provide an engine test apparatus and method, which can easily enhance the test accuracy.The engine test apparatus 10 of the present invention includes: a dynamometer 14, which applies torque to an output shaft of an engine 12 via a shaft member 32; a torque meter 36, which is disposed on the shaft member 32 and measures torque; and a control device 20, which computes a torque command value using a rotational frequency feedback value in order to apply feedback control based on a rotational frequency to the dynamometer 14. The control device 20 subtracts a value measured by the torque meter 14 from the torque command value to find a correction torque command value and controls the dynamometer 14 using the correction torque command value.

Abstract: An engine test apparatus includes a dynamometer connected to an engine through a shaft, and a control calculation device configured to control operations of the engine and the dynamometer. The shaft has one end connected to an output shaft of the engine, and the other end connected to a rotation shaft of the dynamometer, and includes a Doppler velocimeter configured to emit laser light to the one end of the shaft or the output shaft of the engine to contactlessly measure a rotation speed of the output shaft of the engine, and transmit the measured rotation speed to the control calculation device. The control calculation device uses the rotation speed transmitted from the Doppler velocimeter to control the operation of the dynamometer.
