The invention provides a communication apparatus used inside a house, a communication system connected thereto, a communication process, and computer program used therefore. The communication apparatus of the present invention connected via a network to one or more terminal appliances in the house, communicates with the outside via two or more different communication configurations including a first communication configuration with a high speed digital transmission technique and a second communication configuration providing service for telephone subscribers. The communication apparatus is characterized in recognizing a situation thereby to disconnect the first communication configuration and to use only the second communication configuration for communication with the outside.

Communication apparatus of a home security system

A monitoring system for preventing crime in a home, includes a plurality of terminals for monitoring whether predetermined monitoring points are in a stationary or nonstationary state. Further, the monitoring system includes a central processing device for controlling the setting/canceling of alarm operations of the terminals. The central processing device has a communication unit that receives stationary/nonstationary information from the terminals and transmits predetermined information including commands to the terminals. Each terminal has a communication unit that transmits stationary/nonstationary information to the central processing device and receives the predetermined information from the central processing device. Thus bidirectional communication can be achieved between the central processing device and the terminals. The terminals may include a terminal with an emergency call unit which, in an emergency, calls or notifies another, and a terminal having a notification unit which indicates that a nonstationary state has been accepted by a predetermined point of contact.

Monitoring system

An iron has a first base to be directly heated for increasing an amount of accumulated heat, a second base including a soleplate and a thermal resistance layer disposed between the bases. The thermal resistance layer has a greater heat resistance than the first base so that the first base heated by a heater can maintain a higher temperature than the second base. The iron of the present invention can increase an amount of accumulated heat, thereby extending not only an ironing period but also a period for spraying steam. If a weight of the iron is decreased, the iron still can hold approximately the same accumulated heat as a conventional iron so that a lightweight iron can be provided.

Iron with thermal resistance layer

A steam iron with spray mist includes a water tank for storing water, a vaporizing chamber for vaporizing water in the water tank so as to generate steam, a base for forming the vaporizing chamber, a heater for heating the base, a base cover for covering an upside of the base, a first passage for guiding water from the water tank into the vaporizing chamber, a mixing chamber in which water in the water tank is formed into fine particles by the action of flow velocity of steam generated in the vaporizing chamber, a second passage for guiding water from the water tank into the mixing chamber, a steam passage for guiding steam from the vaporizing chamber into the mixing chamber, and a spray nozzle for spraying water from the mixing chamber by the action of steam so that the sprayed water can be sent out from an upper portion of the base to the front.
