  • Patent number: 7509844
    Abstract: Methods and apparatus for automatically determining a feedback setpoint for use in operating an atomic force microscope (AFM) are provided. The setpoint may be determined by modulating a feedback setpoint while monitoring for a change in a detector signal. In an effort to avoid tip damage and remain in non-contact, attractive mode during use, a setpoint just above a setpoint corresponding to a detected change in a parameter of the detector signal, such as an abrupt change in phase, may be used to operate the AFM.

  • Patent number: 7506534
    Abstract: An object is to provide a gas sensor which can suppress positional shift of a to-be-held member such as a gas detection element, as well as a method of manufacturing the gas sensor. A gas sensor (101) includes a gas detection element (111), a metallic shell (131), a plate packing (157), and a first packing (159). A proximal end surface (113t2) of a projection (113) of the gas sensor element (111) and a central inner circumferential surface (135n) of the metallic shell (131) form an acute-angle clearance (120). The first packing (159), which has a wedge-like cross section, is disposed in the clearance (120) such that the first packing (159) is pressed against the proximal end surface (113t2) of the projection (113) of the gas sensor element (111) and the central inner circumferential surface (135n) of the metallic shell (131).

  • Patent number: 7464580
    Abstract: An ionic liquid piezoelectric gas sensor for the detection of polar and nonpolar organic vapors. The gas sensor can operate at high temperatures with a fast linear response which is also reversible. At high temperatures, the frequency change (?f) versus concentration (C) curve mirrors the Henry's gas law, such that the concentration of a gas sample in liquid solvent is proportional to the concentration or partial pressure of the sample in gas phase. The gas sensor can be used for quantitative analysis of gas vapors and determination of Henry constants.
