Abstract: The present invention relates to a cogged V-belt, including a cog portion containing cog ridges and cog valleys, and having a belt thickness of 19 to 36 mm and a cog height of 14 to 19 mm, in which the cog valley has a cross-sectional shape including a bottom portion formed by combining a plurality of continuous arcs and side walls of the cog valley, in which the plurality of arcs has curvature radius decreasing as a distance from a deepest portion of the cog valley increases, and includes a first arc passing through the deepest portion of the cog valley, having a diameter larger than a virtual circle tangent to the deepest portion and the both side walls and having a curvature radius of 7 to 10 mm.

Abstract: To provide a terminal management apparatus capable of improving convenience in a state that power consumption is suppressed. A communication section 501 receives reporting information notifying the presence of a notification utilizing a first communication function directed to a terminal 510. When the communication section 501 has received the reporting information, a control section 502 transmits a message indicating the presence of the notification, to the terminal 510 by using a second communication function different from the first communication function.

Abstract: Certificate data contained in an execution file have been stored as a certificate file in protected data storage area 14 that has been access-restricted. Thereafter, when an execution file that does not contain certificate data is distributed as an update execution tile from application distribution server 40, the update execution file is executed based on the certificate file stored in protection data storage area 14 so as to use the application.

Abstract: A network includes Internet protocol (IP) terminals for establishing communication using an initiation protocol used in connection-oriented communication in which connection to a destination is confirmed over an IP network for the communication; and a server apparatus constituting the network along with the IP terminals. The server apparatus includes a detecting unit for detecting a speech quality between the IP terminals; a calculating unit for calculating an optimal speech quality based on the detected speech quality information; and a notifying unit for notifying the IP terminals establishing communication of the calculated optimal speech quality. The IP terminals establish communication with the speech quality being set to the optimal speech quality, which the server apparatus notifies to the IP terminals.

Abstract: There is disclosed a private branch exchange in which an SIP terminal is capable of receiving great variety of services provided by the private branch exchange without upgrading version of software of the SIP terminal itself. A standard SIP protocol control module 17 and an expanded SIP protocol control module 18 are disposed for SIP corresponding terminals, convert signals from an SIP system protocol corresponding terminal into signals of a protocol inside an IP-PBX 1 to transmit the signals to a PBX basic connection process providing module 12, and convert signals from the PBX basic connection process providing module 12 into signals of an SIP system protocol to transmit the signals to the SIP system protocol corresponding terminal. A PBX additional service providing module 11 and the PBX basic connection process providing module 12 provide additional services in response to an hooking operation from the SIP corresponding terminal or an input of a number for starting the service.
