Abstract: Provided is a metal detector capable of quickly and accurately ascertaining a noise generating situation. A metal detector generates a magnetic field in an inspection region and detects a change in the magnetic field in the inspection region to detect a foreign substance in an inspection object passing through the inspection region. The metal detector measures the change in the magnetic field of the inspection region while changing an inspection frequency, performs frequency analysis of the measurement result, and displays an obtained frequency distribution diagram on the display unit as a noise diagnosis result. In the frequency distribution diagram, target foreign substance reference lines are displayed.

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: Provided is a quantitative dispensing system includes a supply device for supply a weighing object, and a weighing device including a holding unit to hold the weighing object supplied from the supply device, a load sensor unit to detect a load of the weighing object supplied to the holding unit, and an arithmetic processing unit to calculate a weighed value of the weighing object from a detection result on the load and control an operation of the supply device. The arithmetic processing unit performs control to stop the supply device when a current weighed value becomes not less than a supply stop weight value calculated by subtracting a stop weighed value deviation from a supply target weight value. The stop weighed value deviation is calculated in consideration of a flow rate and a supply pressure of the weighing object and a filter setting in the weighing device.
