  • Patent number: 11892428
    Abstract: A laser ablation device is provided with: a laser light source that outputs a femtosecond pulse laser beam; an optical system that includes a first mirror rotatable about a first axis, a second mirror rotatable about a second axis, a first driving source for rotating the first mirror about the first axis, and a second driving source for rotating the second mirror about the second axis, and that reflects the laser beam from the laser light source toward a sample by the first mirror and the second mirror; and an irradiation controller that, on the basis of the two-dimensional coordinate position of an analysis position, controls the first driving source and the second driving source to irradiate the analysis position with the laser beam.

  • Patent number: 9520278
    Abstract: An object is to mix multiple liquids sufficiently and then nebulize the mixed liquids while maintaining the nebulizing efficiency. A nebulizer includes a first inner tube disposed inside an outer tube and having therein a first sample passage through which a first liquid sample flows, a second inner tube disposed inside the outer tube in parallel with the first inner tube and having therein a second sample passage through which a second liquid sample flows, a membranous member disposed with a gap between the membranous member and sample outlets formed at respective ends of the inner tubes. The gap forms mixing space in which a gas passing through a gas passage converts the first and second liquid samples flowing out of the sample outlets into droplets and mixes the droplets and the membranous member has multiple holes through which the mixed liquid samples pass along with the gas.

  • Patent number: 9384956
    Abstract: A nebulizer characterized in being provided with: an inner tube, which is disposed coaxially with an outer tube in which a nebulizing outlet is formed and which, together with the outer tube, forms a gas channel therebetween; a sample channel, which is formed inside the inner tube and through which a liquid sample to be nebulized flows; and a reticular membrane disposed with a gap from the sample outlet that is formed at one end of the inner tube and in which multiple holes, through which liquid sample drops flowing out from the sample outlet pass along with a gas, are formed. Using the nebulizer, the particle size of the nebulized liquid droplets can be made uniformly fine over a broad range of sample liquid flow volumes while retention of sample liquid in the nebulizer is reduced.

  • Patent number: 9291556
    Abstract: An objective optical system for ATR measurement is provided with a housing, in the interior, an ATR crystal that is transparent in visible light and has a semispherical surface through which light enters; an infrared optical member for irradiating a sample with infrared light at an angle that is equal to or greater than the critical angle; a visible light irradiation optical member which is disposed in the interior of the casing and which irradiates the sample with visible light from an angle less than the critical angle; and an observation optical member which is disposed on a position that is offset from the reflection angle relative to the angle at which the visible light enters the sample and which guides the scattering light from the sample to an observation device. As a consequence, it is possible to clearly observe the position of a sample subjected to ATR measurement.

  • Patent number: 6290363
    Abstract: An apparatus for reflecting a light and changing the length of an optical path from a beam splitter to a light reflecting member, and back to the beam splitter, on a cycle at a high speed, includes a beam splitter and at least one light reflecting member that reflects one of the emerged lights from the beam splitter and reenters the light in the beam splitter, the light reflecting member being supported so as to perform a circular locus motion with the orientation of the light reflecting member being constant. The circular locus motion includes a motion in which the light reflecting member is moved in a distance direction with respect to the beam splitter. The light reflecting member is provided with a turning effect, which is converted into a circular locus motion to make the light reflecting member perform the circular locus motion.

  • Patent number: 5595424
    Abstract: A mini plane has a bar-like handle capable of being held in a hand like a pencil, a cutting blade holder fixed on the bar-like handle at a forward end thereof, and a cutting blade detachably attached to the cutting blade holder. The cutting blade has a flat seating face, a front face opposite the seating face, a slant blade face which is slanted at a lateral end portion of the front face, a positioning side face perpendicular to a cutting edge of the slant blade face, and a through hole which extends between the seating face and the front face for receiving a fixing screw. The cutting blade holder has a mounting face to which the seating face of the cutting blade is attached, a positioning reference side face with which the positioning side face of the cutting blade is contacted, and a fixing tapped hole provided in the mounting face with which a tip portion of the fixing screw passing through the through hole is screw-engaged.
