Abstract: In this molded surface fastener, an engaging element includes a columnar stem portion, and micro pawl portions protruding outward from an upper end outer peripheral edge of the stem portion in a plan view of the engaging elements. A pawl width dimension of the micro pawl portions is smaller than a line segment connecting two points on the upper end outer peripheral edge of the stem portion. The micro pawl portions protrude toward a base portion. This molded surface fastener has a high peel strength and a shear strength with respect to a female surface fastener.

Abstract: This manufacturing method of a molded surface fastener involves a primary molding step for forming a primary molded body and a secondary molding step for compressing a provisional element of the primary molded body while heating the same. A molding apparatus is provided with a mold member comprising multiple penetration holes and multiple concave portions, whereof each penetration hole communicates to at least one concave portion; in the primary molding step, the molding apparatus is used to form a primary molded body comprising a provisional element having a primary stem portion and a pawl portion is formed from the protruded portion by compressing the provisional element. By this means, it is possible to stably manufacture a molded surface fastener that has an engaging element comprising a pawl portion that projects from the outer peripheral edge of an engaging head portion.

Abstract: An integrally moldable molded surface fastener retains practical rigidity, while having attraction force to a magnet and is prevented from being easily broken during attachment and detachment handlings to and from loop-shaped engaging elements. A first resin composition including 80% by mass or more of a thermoplastic polyester and containing no magnetic material is used in at least a part of a substrate portion, and a second resin composition containing a thermoplastic polyester, a thermoplastic polyester elastomer and a magnetic material at a certain proportion is used in at least a part of engaging elements of the molded surface fastener.

Abstract: Measurement packets periodically transmitted from a terminal are received by an access point, a reception level value is detected, in the case of the Measurement packet from the terminal which has been notified of connection permission, the reception level value is registered into a management table (association table). In the case of the Measurement packet from the terminal which is not notified of the connection permission, the reception level value is notified to another access point which has been notified of the connection permission and the reception level value from another access point is further registered into the management table. The own reception level value registered in the management table is compared with the reception level value of another access point. If the reception level value of another access point exceeds the own reception level value, the connection permission to the terminal is cancelled and the switching to the next access point is notified.

Abstract: A network control system includes a managing device, separate devices that communicate with the managing device, and a repeater that interconnects the managing device and separate devices. In the network control system, when the managing device performs maintenance, the separate devices each include a separate device side power source control circuit. The power source control circuit controls the on-state and off-state levels of a power source which is to be delivered to a circuit including at least an activating signal monitor unit such as a separate device side wake-up packet monitor unit that monitors whether or not an activating signal such as a wake-up packet sent from tho managing device via the repeater has been received. When the power source control circuit detects that the power source switch of the separate device is in off-state, the power source control circuit suppresses the transmission of a predetermined signal to the repeater.
