Abstract: An ultrasonic imaging device which narrows the width of annular areas to be established, without increasing the number of channels. The controller establishes the annular areas 421 to 42p the number of which is larger than the number of signal lines, along line intersections between wave surfaces 51 to 54 of reflective waves and a multi-dimensional surface of the probe 1. The controller selects multiple annular areas (0, 0), (0, 1), and (0, 2) with focal depths differing, for example, by an integral multiple of the ultrasonic wavelength ?, out of the multiple annular areas being established, and connects the multiple transducer elements positioned within the selected multiple annular areas with an identical signal line. Accordingly, the received signals from the selected multiple annular areas arrive at multiple time points shifted by the time corresponding to the wavelength, and the signals do not cancel one another out.

Abstract: In an electrophotographic photosensitive member according to the present invention, a barrier layer is formed on a conductive substrate; a first layer of a photoconductive layer on the barrier layer, and a second layer on the first layer. Formed of microcrystalline silicon containing hydrogen, the first layer is highly sensitive to long-wavelength light. The second layer contains hydrogen and at least one element selected from carbon, oxygen, and nitrogen. The barrier layer is formed of microcrystalline silicon containing an element included in group III or V of the periodic table. The rectifying action of the barrier layer prevents carriers from being injected into the photoconductive layer from the substrate side. Containing carbon, oxygen, or nitrogen, the barrier layer has high dark resistance and chargeability.

Abstract: In an electrophotographic photosensitive member according to the present invention, a barrier layer is formed on a conductive substrate, and a photoconductive layer on the barrier layer. The photoconductive layer is formed of a microcrystalline silicon layer, whose crystallinity varies all the way through its thickness. The higher the crystallinity of the microcrystalline silicon layer, the more distinguishable are the crystalline properties, the narrower is the optical band gap, and the higher is the sensitivity to long-wavelength light. If the crystallinity becomes lower, then the amorphous properties are enhanced, and the resistance is increased in proportion. Thus, the chargeability and the sensitivity to long-wavelength light of the microcrystalline silicon layer can be improved by varying its crystallinity in the photoconductive layer.
