  • Patent number: 11940347
    Abstract: A pressure sensor has a stem in which a pressure introduction hole into which a pressure medium is introduced and a diaphragm deformable according to the pressure of the pressure medium are formed, and a strain detecting element which is arranged on the diaphragm via an insulating film and being configured to output a detection signal according to the deformation of the diaphragm. The strain detecting element is configured to have a portion made of polysilicon. A low doping layer having a higher electrical resistivity than polysilicon and a higher crystallinity than the insulating film is arranged between the insulating film and the strain detecting element.

  • Patent number: 10984998
    Abstract: In a tandem mass spectrometer, when the measurement mode is switched between a positive ion measurement mode and a negative ion measurement mode, a DC offset voltage applied to a lens electrode to impart collision energy to an ion is temporarily switched to 0V (S1). After being maintained at 0V for a predetermined waiting time (S2), the voltage is changed to a DC offset voltage corresponding to a measurement mode which is used after the switching operation (S3). By such an operation, the voltage difference between the neighboring plate electrodes among the plate electrodes (171, 172, 173) included in the lens electrode can be decreased as compared to the case where the polarity of the DC offset voltage is immediately switched. Consequently, unintended electric discharge between the neighboring electrodes can be prevented.

  • Patent number: 10788466
    Abstract: Provided is a sample introduction system for sequentially introducing a plurality of samples into an analyzer 200, the system including: an auto-sampler 300 including a sampling needle 302 for suctioning a sample from each well 312 provided in a plate 311 placed on a sample rack 310 or from a sample container 313 placed in the well 312, and a needle drive mechanism 303 for driving the sampling needle 302 in horizontal and vertical directions; an operation section 10 for allowing a user to command the needle drive mechanism 303 to drive the sampling needle 302; and a display controller 28 for displaying, on a screen of a display section 30, an identification of the well 312 related to a reference point defined on the plate 311 in a correction process conducted by the user by manipulating the operation section 10 so as to operate the needle drive mechanism 303 so that the sampling needle 302 is transferred to a predetermined position serving as the reference point.
