    摘要： A zoom lens includes: a first lens group having a positive refractive power and statically positioned along an optical axis when a power of the zoom lens is varied or the zoom lens is focused; a second lens group having a negative refractive power; a third lens group having a positive refractive power; a fourth lens group having a positive refractive power; a fifth lens group. The second and fourth lens groups are moved for varying the power of the zoom lens and the fourth lens group is further moved for focusing the zoom lens. The first lens group includes a reflective optical element for bending an optical path. The second lens group includes a cemented lens including a positive lens and a negative lens. The fourth lens group includes two positive lenses, and the fifth lens group includes one positive lens having at least one aspherical surface.

    摘要： The present invention provides a technology including, for example, a packet relay processing section to carry out packet relay, a packet sampling section to carry out packet sampling, a flow statistics counting section to take statistics of each flow, and a flow statistics generating section to generate a NetFlow export datagram, wherein the flow statistics counting section collectively counts the number of the packets or bytes received per unit time when the number does not exceed a threshold value and individually counts the number for each flow when the number exceeds the threshold value, and thereby a flow of abnormal traffic which is suspected to be DoS attack is efficiently detected with small amounts of resources (mainly memories).

    摘要： A data access apparatus has a memory portion including plural memory banks. A data storage control portion stores the pixel data in the plural memory banks with the pixel data being divided into the plural memory banks based on information on an access pattern of plural pixels set on a predetermined screen. A data access control portion reads pixel data relative to the plural pixels specified by the access pattern at the same time from the plural memory banks at each set position in which the set position of the access pattern moves from the start position thereof toward a pixel row direction. A selector portion transmits pixel data corresponding to respective pixels constituting each of the groups of pixels based on correspondence information on input and output. Each group of pixels includes a center pixel and peripheral pixels positioned at a periphery of the center pixel.
