    摘要： A water-lifting pump apparatus which is free of a discharge valve and a check valve, is low in cost, and is capable of reducing vibration and noise due to a waterfall after the end of water pumping operation. The water-lifting pump apparatus has a suction tank (10), a discharge tank (20), a pump (30) for pumping water in the suction tank (10) into the discharge tank (20), and a discharge piping (50) connected to a discharge side of the pump, an actuator (60) for actuating the pump (50), a reverse flow preventing mechanism (80) for preventing a reverse flow of water pumped into the discharge tank (20) toward the discharge piping (50), and a back flow rate control (90) for controlling the flow rate of a waterfall falling from the discharge piping (50) into the suction tank (10) when pumping operation is finished.

    摘要： A vortex prevention device is capable of preventing creation of air entrained vortex and also provides a double suction vertical pump having such a vortex prevention device. The vortex prevention device is used in combination with the double suction vertical pump which is installed in an open channel and has an upper suction opening and a lower suction opening. The vortex prevention device includes a plate member as a vortex prevention structure arranged above the upper suction opening. The plate member is arranged away from the upper suction opening such that a passage is formed between the plate member and the upper suction opening.

    摘要： The objective of the present invention is to provide a zoom lens system having an f-number of approximately 1.3 at the wide extremity, a half angle-of-view of 75 degrees, and a zoom ratio of approximately 3:1. The solution to this objective is to provide a zoom lens system including a first lens group, having a negative refractive power, a diaphragm, and a second lens group, having a positive refractive power, in that order from the object side; wherein the first lens group and the second lens group move in the optical axis direction so that the distance therebetween decreases upon zooming from the wide-angle extremity to the telephoto extremity,

    摘要： An air flow measuring device has a throttle portion provided in a first sub-passage, a second sub-passage branched from the first sub-passage at an upstream side of the throttle portion, and a flow amount sensor located in the second sub-passage. The second sub-passage is configured to introduce therein a part of air flowing in the first sub-passage, and an inlet of the second sub-passage is open into the first sub-passage at one side in a first radial direction perpendicular to a flow direction of air flowing in the first sub-passage. Furthermore, the throttle portion is provided to gradually reduce a passage dimension of the first sub-passage in a second radial direction, as toward an outlet of the first sub-passage. Here, the second radial direction is perpendicular to a surface defined by the first radial direction and the flow direction of air in the first sub-passage.
