    Abstract: In the case of a narrow band in which the number of sub-carriers to be used for the concurrent transmission is smaller than a predetermined value, an RSRP estimation unit carries out processes in an order of time-wise in-phase addition, frequency-wise averaging, and conjugate multiplication, with respect to the channel estimation values estimated by the channel estimation unit; and in the case of a wide band in which the number of sub-carriers to be used for the concurrent transmission is greater than the predetermined value, the RSRP estimation unit carries out processes in an order of frequency-wise averaging, conjugate multiplication, and time-wise in-phase addition, with respect to the channel estimation values estimated by the channel estimation unit.

    Abstract: In an impeller 11, an inlet portion and an outlet portion are provided at one end side and the other end side in the axial direction, respectively. An inlet 29 is formed in the lower part of the inlet portion, and an outlet is formed in the side face of the outlet portion. The inlet portion and the outlet portion are partitioned by a flange portion 40. The impeller 11 includes a primary vane 36 and a secondary vane 38. The primary vane 36 defines a spiral primary channel 35 that connects the inlet 29 and the outlet. The secondary vane 38 is formed in a shape that a part of the outer periphery of the outlet portion is gouged inward so as to define a secondary channel 37 connected to the primary channel 35 and extending circumferentially around the outer periphery.

    Abstract: An improved X-ray analyzer may be made portable and provide accurate positioning capabilities to permit precise location on a sample of a measurement point. An imaging device is provided to allow the user to observe a position at which primary X-rays generated by an X-ray source are to be irradiated onto the sample, and a display device is provided for displaying an image thereof. The display device displays a fluorescent X-ray spectrum taken at a measurement point on the sample in accordance with an output of an X-ray detector at the same time as displaying the sample image.
