An object of the present invention is to obtain an apparatus and a method for the detection of chemical agents which are suitable for detecting sulfur mustard and lewisite 1 and are satisfactory from the viewpoint of the speed of detection of chemical agents, the reduction of the rate of wrong information, the specification of the kinds of the chemical agents, and an unmanned continuous-monitoring apparatus. In the present invention, the detecting apparatus comprises a sample introduction section 1 into which a sample is introduced to be heated, an ionization section 2 in which the sample from the sample introduction section is ionized, a mass spectrometry section 3, and a computer 6 for data analysis. When predetermined signals characteristic of sulfur mustard or lewisite 1 are observed, it becomes possible to specify the sample.

Apparatus and method for detecting chemical agents

A packet switch having a structure of writing a variable length packet received from each of input lines into a shared buffer memory on a fixed length data block unit basis, wherein a buffer controller forms an input queue for each input line and, when the last data block of a variable length packet is registered in the input queue, links a linked address list for the input queue to one or a plurality of output queues corresponding to one or a plurality of packet destination output lines.

Shared buffer type variable length packet switch

An apparatus for detecting a chemical agent, capable of increasing a detection speed of a chemical agent, decreasing a false alarm rate, pinning down the kind of a chemical agent, and meeting specifications for unattended continuous monitoring equipment suitable for detecting sarin or soman. This detection apparatus comprises a sample introduction unit for introducing a sample, an ionizing unit for positively ionizing the sample from the sample introduction unit, a mass spectrometer unit for analyzing ions of the sample, and a computer for analyzing data, and is best suited for identifying a dangerous substance by detecting signals peculiar to chemical agents, such as sarin or soman.

Chemical agent detection apparatus and method

A video telephone system which includes a master video telephone terminal (secretary terminal) connected to a communication network and slave video telephone terminals (executive terminals) connected to the master video telephone terminal in which the master video telephone terminal can transfer a call to the slave video telephone terminals. When a call comes into the secretary terminal from a remote terminal on the communication network, a line control section of the secretary terminal sets up a line. Video data and speech data received on the line are decoded by a video signal coding-decoding section and an aural signal coding-decoding section and the decoded signals are output through a display and a speech output device. Sound and images picked up by a microphone and a camera respectively are coded for transmission. Then, if a predetermined instruction of call transfer to an executive terminal is entered on an electronic tablet of the secretary terminal, a communication branch control section of the secretary terminal calls the executive terminal, sets up a line between the secretary and executive terminals on a local transmission network, and connects the line between the secretary terminal and the remote terminal.
