Abstract: A roller unit aligns tapes in a width direction and feeds the tapes in a length direction while pressing the tapes in a thickness direction. The tapes are made of fibers which have not been impregnated with resin or have been impregnated with the resin. The roller unit includes rollers and a support shaft. The rollers rotate by friction force between the tapes and the rollers. The rollers are aligned so that rotation axes lie on a same straight line. Maximum diameters of the rollers are same as each other. The support shaft supports the rollers rotatably at rotational speeds independent from each other. Each of the rollers includes springs and thereby has elasticity. Length directions of the springs as well as expansion and contraction directions of the springs are radial directions of the each of the rollers. The springs are radially disposed inside the each of the rollers.

Abstract: A gateway device (10) stores therein a first filtering rule and a second filtering rule for filtering packets which are transmitted from a terminal (20) in a network (2) as a transmission source to a terminal (20) in a network (3) as a destination. The gateway device (10) acquires, on the basis of a packet transmitted from the terminal (20) in the network (3), identification information for identifying the terminal (20). The gateway device (10) notifies a management device (30) of the acquired identification information. The management device (30) generates a management screen on the basis of the notified information, and transmits the management screen to a display device (40). The management device (30) transmits an instruction based on input to the display device (40) to the gateway device (10). The gateway device (10) sets the first filtering rule on the basis of the instruction from the management device (30).

Abstract: When an attack is detected, a controller samples an attack-target addressed DNS reply, received by a border router, from each of the border routers. Then, the controller adds the transmission-source IP address of the sampled DNS reply to the black list of the border router. Furthermore, upon reception of any of a target-addressed DNS reply and a target-addressed UDP subsequent fragment from the IP address that is described in the black list, the controller gives a command to the border router to discard the packet. Furthermore, the controller specifies the setting, for each of the border routers, that DNS replies to a DNS request from the target are excluded from discarding.

Abstract: A solar light (heat) absorption material which has an excellent solar light (heat) absorbing ability and a simple structure, and may be used as a low-cost and high-performance heat absorption/accumulation material. Also, a solar light (heat) absorption/control building component including the solar light (heat) absorption material that allows for easy change of its solar light (heat) absorption/control ability. The material includes particles dispersed into a liquid medium having a specific heat ranging from 0.4 to 1.4 cal/g/° C. and a melting point of 5° C. or lower. The dispersed particles have L*value of 30 or less as determined by the CIE-Lab color system (light source D65).

Abstract: An unauthorized-access detection device in which when a relationship between information regarding a request transmitted from a terminal operated by a user to a service server that provides a service, which is acquired by a request acquisition unit, and information regarding a query transmitted from the service server to a DB that accumulates information regarding the service, which is acquired by a query acquisition unit, is different from a normal pattern, a detection unit detects the query as unauthorized access to the DB.
