A terminal system has a mass spectrometric for inspecting of dangerous substances is installed in an inspection area, and a support system for determining whether or not a dangerous substance is present and identifying the type of the substance, based on the mass spectrometric data on the target element that has been measured by the mass spectrometric, is installed in a security service enterprise's office. Both systems are connected to each other via a communication network so that they can exchange information. Thus, the support system can send the determination result of dangerous substances and a precautions guide to the terminal system via the communication network.

A hazardous material detection system that can suppress occurrence of contamination due to ionization. When a sensor detects that a test sample has entered an inspection region of an X-ray inspection device as a belt conveyor moves, a corona discharge power supply in a hazardous material detection device is turned on for a constant time, to introduce a qaseous sample containing a substance stuck to the test sample into the hazardous material detection device via a sucking section and gaseous sample introduction piping, in order to ionize the gaseous sample and analyze it at an analyzer, based on a result of which analysis, a data processor decides whether the gaseous sample contains a hazardous material, to display a decision result on a screen. When the test sample is detected by an exit side sensor, the corona discharge power supply is turned off.

A facsimile system with the body thereof usable as a subunit of a cordless telephone is disclosed. A parent unit is connected to the telephone line. A facsimile subunit is connected by radio to the parent unit. A telephone subunit is also connected by radio to the parent unit. A circuit included in the parent unit detects a signal indicating that the other party is in facsimile transmission mode. When a call signal is detected from the telephone line, the parent unit connects the line. When a CNG signal is detected, on the other hand, the parent unit connects the facsimile subunit by radio. In the case where a CNG signal is not detected, the parent unit starts the ring-up tone on the telephone subunit. An AGC circuit and a voice mute circuit are included in the parent unit.

Cordless subunit facsimile system

A voice/image simultaneous communication apparatus which can transmit image data while permitting talking with higher efficiency by encoding voice and synthesizing voice coded data and image data than by multiplexing frequencies. The voice/image simultaneous communication apparatus is constructed of a voice coder for coding an analog voice signal, a voice decoder for decoding the coded voice into an analog voice signal, a data synthesizer for synthesizing image coded data and voice coded data, a data separator for separating synthesized coded data into image coded data and voice coded data, and a modem capable of performing full duplex communication. The data synthesizer can change the ratio of synthesis between voice coded data and image coded data in accordance with the data transmission speed.
