Abstract: The present invention provides a solar heat collecting device having good heat collection efficiency. A uniaxial solar-tracking reflective mirror group is arranged such that each longitudinal axis thereof faces the same direction. A first biaxial solar-tracking reflective mirror group and a second biaxial solar-tracking reflective mirror group are arranged lined up in a direction orthogonal to the longitudinal axis direction of uniaxial solar-tracking reflective mirrors. The uniaxial solar-tracking reflective mirror group is arranged so as to be sandwiched on both sides by the first biaxial solar-tracking reflective mirror group and the second biaxial solar-tracking reflective mirror group. Each mirror group sends solar heat received during uniaxial or biaxial tracking in accordance with the position of the sun, to a heat collecting device.

Abstract: A solar heat collector with high heat collection effect is provided. The solar heat collector includes a first heat collection pipe and a second heat collection pipe. The first heat collection pipe receives reflected light from a single-axial tracking solar type reflective mirror group to collect heat. The second heat collection pipe receives reflected light from the single-axial tracking solar type reflective mirror group and dual-axial tracking solar type reflective mirror groups to collect heat. The second heat collection pipe has an amount of heat collection per unit area larger than the first heat collection pipe. Therefore, compared with the use of only the first heat collection pipe, this ensures obtaining larger energy.

Abstract: A flush toilet device has a toilet body having a bowl section, rim water discharge opening, a jet water discharge opening, and a discharge water trap conduit. A pressurizing pump is provided for pressurizing flush water contained in a cistern to supply it to the jet water discharge opening. A pump controller regulates the operation and rotation speed of the pressurizing pump to regulate the flow speed and flow rate of flush water discharged from the jet water discharge opening so that flush water at a first flow rate for generating a siphon effect is discharged and then at a second flow rate is discharged at the end of the siphon effect generated by the first flow rate. The second flow rate having a flow speed that can carry away human wastes and causes the siphon effect to continue by closing the cross section of any portion of the discharge water trap conduit.

Abstract: A speed change gear includes: an internal gear member; an eccentric member; an oscillating member; a pair of first and second rotating members; and a pin that is supported at both ends by insertion holes of the first and second rotating members. The insertion hole and the insertion hole have the same diameter. The outside diameter of the other side end portion of the pin is smaller than the outside diameter of one side end portion of the pin such that the one side end portion is press-fitted in the corresponding insertion hole and the other side end portion is supported by the corresponding insertion hole.

Abstract: A suction filter may comprise a bag-shaped filter member and a passage member. The passage member is disposed in an internal space of the filter member. The passage member has a fuel passage and a plurality of openings, and guides fuel from the internal space to the outside of the internal space. The openings communicate the internal space of the filter member to the fuel passage. When the passage member is cut along a surface thereof perpendicular to a longitudinal direction of the passage member in each of the openings, a position on an outer circumferential surface of the passage member in the cut surface, in which the distance between the outer circumferential surface and the filter member is the smallest, is distant in a circumferential direction from a position on the outer circumferential surface where the opening is formed.
