Abstract: Sinusoidal signals (S1, S2) having a phase difference of 120° are output from two magnetic sensors in accordance with rotation of an input shaft. A first rotation angle computation unit computes a rotation angle ?(n) on the basis of output signals S1(n), S1(n?1), S2(n), S2(n?1) from the magnetic sensors, which are sampled at two sampling timings. At this time, the first rotation angle computation unit computes the rotation angle ?(n) on the assumption that there are no variations of amplitudes of the output signals (S1, S2) from each one of the two sensors due to temperature changes between the two sampling timings.

Abstract: A power generation device includes a main shaft rotated by an external force, a speed-up gear, a high-speed shaft, a rolling bearing, a power generator, and a one-way clutch disposed between the output gear and the high-speed shaft. In a state where the main shaft is rotating in a positive direction, the one-way clutch integrally rotatably connects the output gear and the high-speed shaft to each other if a rotational speed of the output gear exceeds a rotational speed of the high-speed shaft, and breaks connection between the output gear and the high-speed shaft if the rotational speed of the output gear becomes lower than the rotational speed of the high-speed shaft.

Abstract: A one-way clutch structure includes: a pair of clutch members disposed between an output shaft and a drive shaft so as to oppose each other in an axial direction; and an engagement element interposed between these clutch members. When a rotation speed of the output shaft exceeds a rotation speed of the drive shaft, the engagement element engages with the clutch portion to connect the output shaft and the drive shaft so as to be integrally rotatable. When the rotation speed of the output shaft becomes lower than the rotation speed of the drive shaft, the engagement of the engagement elements is released to cut off connection between the output shaft and the drive shaft.

Abstract: In a rotation angle detection device, when a condition that two sensors among three magnetic sensors sense one and the same magnetic pole for three consecutive sampling periods is satisfied, a rotation angle is computed based on output signals from the two sensors, sampled at three sampling timings. When the output signals sampled at the three sampling timings satisfy a prescribed requirement, an angular width error correction value corresponding to the magnetic pole sensed by the two sensors and amplitudes are computed, and stored in association with the magnetic pole. If the condition is not satisfied, the rotation angle is computed based on the information stored in a memory and the output signals from two sensors among the three magnetic sensors, the two magnetic sensors including one of the three magnetic sensors, which detects the magnetic pole of which the angular width error correction value is stored in the memory.

Abstract: In a phase difference detector, a first phase difference computation unit computes a value of E(i)·C corresponding to one and the same given magnetic pole sensed by the two magnetic sensors with use of six output signals sampled at three different timings while the two magnetic sensors are sensing the given magnetic pole when a rotary body is rotating. E is an angular width error correction value, and C is a phase difference between two signals. The first phase difference computation unit executes this process until values of E(i)·C corresponding to all the magnetic poles are computed. After that, the first phase difference computation unit computes the phase difference between the output signals with use of the values of E(i)·C corresponding to all the magnetic poles and the number (m) of the magnetic poles.

Abstract: Rotation angle computation modes include a normal mode and a simple mode. In normal mode, a rotation angle of an input shaft is computed based on output signals from first and second magnetic sensors, which are sampled at two sampling timings. In simple mode, the rotation angle of the input shaft is computed based on the output signals from the first and second magnetic sensors, which are sampled at one sampling timing, and an amplitude ratio between the output signals from the magnetic sensors set in advance. After a power supply is turned on, the rotation angle is computed in the simple mode until a condition that the rotation angle of the input shaft can be computed in the normal mode even if the immediately preceding value of the rotation angle of the input shaft is not present is satisfied. Then, the rotation angle is computed in the normal mode.

Abstract: When a cleaning button for cleaning the toilet bowl is operated, by a manner as pressing, a switching valve 41 switches the flushing water supply destination to a position for cleaning the bowl part. The flushing water is then jetted out of a spout nozzle 35 disposed inside a Z water conduit 161 as a jet flow. The jet flow from the spout nozzle 35 causes water inside the Z water conduit 161 and water inside the flushing water reservoir 104 to flow through the Z water conduit 161 and to be spouted toward an inlet 121 of a waste trap 102, like a jet flow spouted by a jet pump. This supplies a heavy flow of flushing water amplified in the volume into the waste trap 102 all at once to flush out the filth in the bowl part 101.
