Abstract: A waste decomposition apparatus has a container-shaped body, a waste inlet for introducing wastes into the body, an outlet for discharging residual ash out of the body after the wastes introduced into the body are decomposed, and magnetic functioning means for inducing magnetic fields in the wastes introduced into the body. The waste decomposition apparatus includes pressing means for pressing the wastes introduced into the body.

Abstract: A telephone communication method capable of promoting the efficient use of the limited number of IP (Internet Protocol) addresses is disclosed. When a call is originated on a first telephone terminal, a first gateway accommodating the terminal accesses a DNS (Domain Name System) server via a UDP (User Datagram Protocol) channel of Internet or Intranet. The first gateway inquires the DNS server of the IP address of a second gateway accommodating a telephone terminal to be called, using an office number assigned to the second telephone terminal as a host name. The DNS server returns the IP address of the second gateway to the first gateway via the UDP channel. In response, the first gateway selects its own IP address for speech transfer and sends a call connection request to the second gateway on a TCP (Transmission Control Protocol) channel of Internet.
