  • Patent number: 10001130
    Abstract: A vacuum pump configured to exhaust gas includes an inductance gap sensor positioned oppositely near an end face of a rotational axis of a rotational body including a rotor; a plurality of individually formed recesses disposed at the end face facing the gap sensor at respectively different angular positions; and at least one ferromagnetic body disposed in at least one of the recesses. The ferromagnetic body has a Curie temperature approximately equal to an allowable temperature of the rotor. The gap sensor senses inductance changes associated with changes in magnetic permeability of the ferromagnetic body to detect a temperature of the rotor. One of the recesses where the ferromagnetic body is not disposed is a rotational number sensor target. Thus, a rotational number of the rotor is detected based on a change in inductance when the rotational number sensor target passes opposite the inductance sensor.

  • Patent number: 10002414
    Abstract: A representative value calculator calculates a representative value which is a luminance value representing a main inspection object area from an input image. On the other hand, an image divider divides an image area of the input image, and sets a plurality of divided ranges. A factor calculator calculates a tone conversion factor for enhancing or suppressing contrast adjacent the representative value calculated by the representative value calculator for each area (each divided area) divided by the image divider. A tone converter converts the tone of each pixel of the input image based on the tone conversion factor for the range divided by the image divider, which range includes a pixel for image processing, and ranges adjacent that range. As a result, the contrast of the area for which enhancement is desired can be enhanced optimally.

  • Publication number: 20180166605
    Abstract: A passage (3) for a sample solution is formed in a sapphire base body (2) used as a substrate for semiconductor devices. An LED (4) and a photodiode (5) are formed on the base body (2) by a semiconductor manufacturing process so that they face each other across the passage (3). The LED (4) emits light into the base body (2). This light is transmitted through the sample solution in the passage (3), undergoing absorption according to the concentration and other properties of the solution. The transmitted light passes through the base body (2) and reaches the photodiode (5), producing a detection signal corresponding to the incident light amount. Since the light source and photodetector are integrated with the base body (2) serving as a flow cell, the present device is small and lightweight. Furthermore, no cumbersome task of aligning optical axes in the device-assembling process is needed.

  • Patent number: 9997343
    Abstract: An electrostatic ion trap for mass analysis includes a first array of electrodes and a second array of electrodes, spaced from the first array of electrode. The first and second arrays of electrodes may be planar arrays formed by parallel strip electrodes or by concentric, circular or part-circular electrically conductive rings. The electrodes of the arrays are supplied with substantially the same pattern of voltage whereby the distribution of electrical potential in the space between the arrays is such as to reflect ions isochronously in a flight direction causing them to undergo periodic, oscillatory motion in the space, focused substantially mid-way between the arrays. Amplifier circuitry is used to detect image current having frequency components related to the mass-to-charge ratio of ions undergoing the periodic, oscillatory motion.

  • Patent number: 9995922
    Abstract: Provided is an analysis target region setting apparatus that can accurately set an analysis target region, based on an observation image of a sample obtained with an optical microscope and the like irrespective of texture on the sample surface when the analysis target region is set therein. The analysis target region setting apparatus according to the present invention divides the observation image into a plurality of sub-regions based on pixel information on each pixel constituting the observation image. Subsequently, consolidation information on each sub-region is calculated, and two adjacent sub-regions themselves are consolidated based on the consolidation information. According to this, it is possible to divide the observation image into sub-regions having similar pixel information with a disregard of noise attributed to the shape of a surface and the like. A user designates one sub-region from among the sub-regions finally obtained, as the analysis target region.

  • Patent number: 9989504
    Abstract: The operation efficiency and accuracy of the simultaneous analysis of phospholipids, including fatty acid compositions are increased. After a first-time LC/MS/MS analysis for determining the phospholipid classes of the phospholipid contained in a sample is performed (S2-S3), a second-time LC/MS/MS analysis for determining fatty acid compositions is performed only for the detected phospholipids (S4-S8). By associating a method list in which an MRM transition for phospholipid class determination is recorded for each compound of phospholipid classes with a method list in which an MRM transition for fatty acid composition determination is recorded for each phospholipid compound, it is possible to promptly select MRM transitions for fatty acid composition determination that correspond to compounds of the detected phospholipid classes, and to easily create an analysis method for the second-time analysis.
