摘要:
To clean sediments and the like trapped not only in a top layer of a sand filtration layer, but also in intermediate layers. A seawater infiltration method which uses a water infiltration intake unit which is formed in advance and provided with a water intake pipe embedded in a gravel layer which forms a deep layer of the sand filtration layer, and a backwashing pipe embedded in a sand layer which forms an intermediate layer and a surface layer of the sand filtration layer, and a water suction pipe which is disposed above the sand layer. A desired number of water infiltration intake units are combined to form a sand filtration layer at an installation site on an ocean floor, and they intake seawater from the sea which has undergone natural infiltration in the sand filtration layer and this is introduced into the water intake pipe. The seawater infiltration rate is set at less than 400 m/day. Water or air is injected from the backwashing pipe to agitate and blow upward from the surface layer living organisms or sediments trapped in intermediate layers of the sand filtration layer, and the agitated water is sucked in by a suction pipe and recovered. The seawater infiltration rate can be maintained as high as possible under 400 m/day.

To provide a cleaning apparatus suitable for removing clogging substances trapped in a surface layer of a sand filtration layer. A cleaning apparatus equipped with drive wheels serving as a driving device configured to move across a surface of a sand filtration layer. A pump and a jet nozzle are provided as an agitation device configured to agitate a surface layer portion of the sand filtration layer only at a desired depth, and which blows the clogging substances upward into the seawater in a turbid water intake pit together with a filtration sand. A perforated pipe for suctioning turbid water, a pump, an ejector, and a discharge pipe for dilute turbid water are provided as a suction and discharge device configured to suction turbid water blown upward into seawater in the water intake pit by the agitation device, and discharge it to outside of the turbid water intake pit. Prevents clogging by performing a timely cleaning of the sand filtration layer, thereby making it possible to maintain a high-speed seawater infiltration rate for seawater. Impact on the surrounding environment is reduced, because the apparatus suctions turbid water containing clogging substances which is blown upward into the turbid water intake pit, and discharges it to outside of the system.

Provided is a vehicle seat by which an impact of rear end collision is reduced and of which peripheral structure of a side frame is simplified. A vehicle seat includes: a seat back frame which includes side portions positioned at the sides thereof, a pressure receiving member which is jointed to the seat back frame through joint members and supports an occupant, and an impact reduction member which is disposed on at least one of the side portions to engage with the joint member and to move by a predetermined amount of impact load applied to the pressure receiving member so that the pressure receiving member is caused to move rearward; in which the side portion includes a convex portion protruding in the movement range of the impact reduction member, and the impact reduction member abuts against the convex portion so that the movement of the impact reduction member is prevented.

Even in the case of a sample exhibiting low photoresponse, such as a wide bandgap semiconductor, a measurement method which enables highly accurate CPM measurement is provided. When CPM measurement is performed, photoexcited carriers which are generated by light irradiation of a sample exhibiting low photoresponse such as a wide bandgap semiconductor are instantly removed by application of positive bias voltage to a third electrode which is provided in the sample in addition to two electrodes used for measurement. When the photoexcited carriers are removed, even in the case of the sample exhibiting low photoresponse, the controllability of a photocurrent value is improved and CPM measurement can be performed accurately.

A fluorescence correlation spectroscopy analyzer 1 is equipped with an excitation light illuminating optical system 21, a fluorescence imaging optical system 22, a CCD camera 15, and a data analyzer 16. The excitation light illuminating optical system 21 illuminates excitation light onto a predetermined region of a measured sample S. The fluorescence imaging optical system 22 images the fluorescence generated at the measured sample S onto the photodetection surface of the CCD camera 15. The CCD camera 15 performs photoelectric conversion of the fluorescence made incident onto the photodetection surface in accordance with the respective pixels and outputs the charges generated by the photoelectric conversion as detection signals from an output terminal. The data analyzer 16 inputs the detection signals based on the charges generated at the pixels, and computes autocorrelation functions of the input detection signals according to each pixel.
