Abstract: A relay device 10 is a relay device for relaying a communication message on a packet-by-packet basis, which comprises an order determiner 13 for determining whether a packet received is one received in an order to be received, a packet holder 14 for, when it is determined that the packet is not one received in the order to be received, holding the packet, and for performing such a control as to relay the packet, a merger 15 for merging a payload of the received packet with a payload of the held packet, a verifier 16 for verifying whether a payload of a packet satisfies a predetermined rule, and a relay controller 17 for, when a packet satisfies the rule, performing such a control as to execute relay of the packet. This prevents an increase of a communication delay and enables detection of an irregular communication message in an application layer protocol, irrespective of types of protocols.

Abstract: After a camp-on to a telephone B has been registered by a telephone A, when a callback is returned by detecting call termination of the telephone B, the callback can be temporarily released or the camp-on can be released by performing a release operation from a telephone D registered in the same group as the telephone A.

Abstract: A method and apparatus for filling bulk material, in which an objective filling weight for filling bulk material stored in a storage portion of a filling object is divided to a first stage objective filling weight and a second a second stage objective filling weight. The method consists of setting an opening/closing mechanism provided on the storage portion to a predetermined opening degree and filling the bulk material from the storage portion to the filling object until the first stage objective filling weight is reached, and then activating the opening/closing mechanism so as to close from the predetermined opening degree. A closing travel distance of the opening/closing mechanism in a certain minute time interval, and a filling weight of bulk material are then detected, and based on these detected values, the fluidity of the bulk material in such a minute time interval is calculated.
