  • Patent number: 10041914
    Abstract: A degassing device 2 includes: a built-in absorbance measurement section 28 using an LED light source and measuring the intensity of light transmitted through a mobile phase passing through a flow cell; and a solenoid valve 26 switchable between two states with and without the mobile phase passed through a degassing tube 21. The passage-switching operation by the solenoid valve is performed so as to obtain detection signals of the transmitted light in the absorbance measurement section when the mobile phase drawn from a mobile phase container by a liquid-feeding pump 40 is passed through the degassing tube for degassing as well as when the mobile phase is not passed through the degassing tube for degassing. A signal processor 29 calculates the difference in absorbance based on those detection signals, estimates the degree of degassing based on that difference, and displays the result on a display unit 32.

  • Publication number: 20160313248
    Abstract: Light emitted from a light casting unit 1 including an LED as its light source is cast into a sample cell 2, and a photodetector 3 is placed at a position where the resultant passing light can be detected. The LED is driven to blink, and a data extracting section 71 extracts data obtained in a period in which the LED is turned on, as data (absorbance data) in which absorption of light by the sample solution is reflected. Moreover, in the case where a fluorescent component is contained in the sample solution, fluorescent light is emitted by the cast light serving as excitation light. Even after the excitation light ceases, the emission of the fluorescent light continues for a short time, and hence the data extracting section 71 extracts data obtained immediately after the LED is turned off, as data (fluorescence data) in which the fluorescent light is reflected.

  • Patent number: 8758464
    Abstract: The disclosed exhaust treatment device for a diesel engine can prevent heat damage to a DPF when regenerating said DPF. If a selection device (7), which selects whether to allow or prohibit an automatic DPF regeneration process, is set to prohibit the automatic DPF regeneration process, a DPF regeneration control device (4) is made able to start a process to cancel execution of the automatic DPF regeneration process. If the selection device (7) is set to allow the automatic DPF regeneration process, the DPF regeneration control device (4) retracts the cancellation of the automatic DPF regeneration process, allowing execution of the previously-cancelled automatic DPF regeneration process to begin.

  • Patent number: 8484958
    Abstract: An object of the present invention is to provide the exhaust treatment device of a diesel engine which is capable of prohibiting the execution of DPF regenerating processing in a situation in which the DPF regenerating processing is inappropriate. In order to achieve the object, DPF regenerating mode switch manipulation means (7a) switches a DPF regenerating mode to a normal and acceleration coexistence regenerating mode (51) or an acceleration-sole regenerating mode (52), and DPF regenerating selection manipulation means (7b) switches a position to a normal regenerating permission position (53), a normal regenerating cancel position (54), or an acceleration regenerating execution position (55). When the DPF regenerating mode is in the acceleration-sole regenerating mode (52), the DPF regenerating control means prohibits normal regenerating processing by the DPF regenerating means irrespective of a position selected by the DPF regenerating selection manipulation means (7b).

  • Patent number: 8226201
    Abstract: The ejection positions of a plurality of pre-processing agent ejection nozzles and the ejection positions of a plurality of ink ejection nozzles as seen in a direction orthogonal to the transport direction of a recording medium are in a one-to-one correspondence with each other. A controller causes the process of ejecting ink of a first color from the ink ejection nozzles onto the recording medium subjected to the ejection from the plurality of pre-processing agent ejection nozzles so as to form a failure detection printing pattern which is a printing pattern formed by providing a time lag between the processes of ejecting the ink from adjacent ones of the plurality of ink ejection nozzles. An ejection failure in the pre-processing agent ejection nozzles is detected by judging that a pre-processing agent ejection nozzle corresponding to a region where bleeding results suffers the ejection failure.
