  • Patent number: 7091870
    Abstract: 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.

  • Patent number: 6770877
    Abstract: A method and apparatus for analyzing vapors generated from explosives in which vapors containing nitrogen monoxide and/or nitrogen dioxide are generated by decomposing explosives by increasing the temperature of the explosives, primary ions and neutral molecules are generated from air. The generated primary ions and the nitrogen monoxide and/or nitrogen dioxide contained in the generated vapors are allowed to react with each other in an area inhibited or prevented from being penetrated by the generated neutral molecules, and the nitrogen monoxide and/or nitrogen dioxide contained in the generated vapors is ionized. The ionized nitrogen monoxide and/or nitrogen dioxide is subjected to mass spectrometry, and an amount of the nitrogen monoxide and/or nitrogen dioxide contained in the generated vapors by decomposing the explosives is determined.

  • Publication number: 20030009661
    Abstract: A terminal system 1 which has mass spectrometric means for inspecting for dangerous substances is installed in an inspection area, and a support system 2 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 said mass spectrometric means, 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 2 can send the determination result of dangerous substances and a precautions guide to the terminal system 1 via said communication network 3. The security service enterprise conducts equipment management, such as maintenance and checkups, and operation administration of the security system, thereby making it easier for a user to introduce this security system.

  • Patent number: 5173735
    Abstract: An image forming apparatus according to the present invention includes a photoreceptor, an image forming unit for forming a toner image on the photoreceptor, an intermediate transfer medium to which the toner image formed on the photoreceptor is transferred at a transfer position and from which the transferred toner image is transferred to a sheet, a cleaning unit for removing toner on the intermediate transfer medium, and a controller for providing control for the sequence of activating a preliminary cleaning of the transfer belt for a predetermined time period, starting image formation after the preliminary cleaning is terminated, actuating a subsequent cleaning after termination of the transfer process, and then starting image formation in response to an image formation start signal output during the subsequent cleaning.
