摘要： A preload measuring apparatus to measure the preload of a rolling bearing that includes a bearing support, a pressurization device, an excitation device, a vibration sensor, and a control section. The bearing support supports a rolling bearing by supporting both ends of a shaft inserted into an inner ring of the rolling bearing. The pressurization device loads a predetermined weight in the axial direction onto the rolling bearing. The excitation device applies vibration onto the rolling bearing by the drive of the piezoelectric elements. The vibration sensor detects the vibration generated on the rolling bearing by the vibration application of the excitation device. The control section operates the excitation device in the situation that the pressurization device presses the rolling bearing, and obtains the resonance frequency by the output signal from the vibration sensor and calculates the preload of the rolling bearing according to the obtained resonance frequency before the predetermined weight as loaded.

摘要： A sheet conveying device includes: a conveying unit; a nonvolatile memory; and a controller. The conveying unit is configured to convey a sheet along a conveying path. The controller is configured to control the conveying unit to convey the sheet, store position data in the nonvolatile memory during conveyance of the sheet, determine whether or not the sheet conveying device is started, and drive the conveying unit for an amount determined by the position data if the sheet conveying device is started. The conveying path is divided into a plurality of segments. The position data identifies a segment in which the sheet stays. The more downstream the segment identified by the position data is in the conveying path, the smaller the amount determined by the position data is.

摘要： A power supply circuit drives circuits having different numbers of series-connected LEDs without changing a circuit constant or a component. An LED series circuit is connected to a power converter circuit of a power supply circuit. The power converter circuit is controlled by a control arithmetic circuit, and supplies a constant current to the LED series circuit. A voltage detection circuit detects a voltage applied to the LED series circuit. The control arithmetic circuit checks whether the LED series circuit has 40 LEDs or 20 LEDs, based on the voltage detected by the voltage detection circuit. The control arithmetic circuit holds a constant-current value table for 40 LEDs and a constant-current value table for 20 LEDs. In accordance with the detected voltage, the control arithmetic circuit selects one constant-current value table, and controls the power converter circuit based on the constant-current value table selected.
