Abstract: A material for assisting metal machining process, having a polymer compound, wherein a content of the polymer compound is 50% by mass or more based on the total amount of the material for assisting metal machining process, a melting point is 40° C. or more, and a temperature at 5% weight loss is 275° C. or more.

Abstract: A computer system 1 has a PBX 2, a terminal device 3, and a management server 4. The PBX 2 has a line controller, an extension controller 2b, an interface, a memory that stores identification information and an enciphered file, a decoder that decodes the enciphered file, a comparator that compares the identification information and the enciphered file decoded by the decoder, and a controller. The terminal device 3 reads the identification information from the PBX 2 and transmits that to the management server 4. The management server 4 has an authenticator that receives a request for authentication when the terminal device 3 logs in, an issuer that issues the enciphered file according to the identification information, and a database that stores the issue date in correlating with the identification information.

Abstract: A terminal apparatus includes a communication unit connected to a private branch exchange and other terminal apparatus; a memory unit for storing address information for the other terminal apparatus; and a controller which, when receiving an incoming call command containing address information for the terminal apparatus as destination information from the private branch exchange via the communication unit, informs a user of the terminal apparatus of an incoming call addressed to the terminal apparatus, generates a substituted incoming call command in which the address information contained in the incoming call command is substituted with the address information for the other terminal apparatus stored in the memory unit, and transmits the substituted incoming call command to the other terminal apparatus via the communication unit so that the other terminal apparatus informs a user of the other terminal apparatus of the incoming call addressed to the terminal apparatus.

Abstract: A private branch exchange has a terminating classification table for storing, in connection with terminating information transmitted through an outside line circuit, destining extension numbers and additional parameters by relating them to each other and a control unit for controlling the above components. When a call terminates at the outside: line circuit, the control unit picks up a destining extension number corresponding to terminating information from the terminating classification table, delivers a terminating signal from a corresponding extension line circuit and also delivers a corresponding additional parameter in the form of an additional parameter signal from the inside line circuit.
