Abstract:
PURPOSE: A very small angle neutron scattering apparatus is provided to reduce the time for measuring the neutron scattering because a plurality of analyzers is installed in a path of the neutron light passed through a monochromator and sample. CONSTITUTION: A very small angle neutron scattering apparatus comprises a first previous monochromator(110), a first monochromator(120), and a first analyzer set(200). The previous monochromator is arranged in a path of the neutron light. The previous monochromator diffracts the neutron light passing through a neutron light path(101) at the Bragg scattering angle. The first monochromator is composed of a monocrystal diffracting diffracted the neutron light at the Bragg scattering angle by the previous monochromator toward a sample side. The first analyzer set is composed of two or more detectors and analyzers(210,220,230). The detector respectively detects the diffracted the neutron light at the Bragg scattering from each two or more analyzers.
Abstract:
An antibacterial imidazolium compound, a photocurable coating composition, and an antibacterial coating of the present invention comprise a compound represented by chemical formula 1 or derivatives of the same compound. Explanation about the X^-, R^1, and R^2 in chemical formula 1 is the same as stated in the detail description of the present invention. The antibacterial imidazolium compound has an excellent antibacterial effect against various strains so that the antibacterial coating can be provided by simply being added to the photocurable coating composition. Additionally, the antibacterial coating comprises a monomeric antibacterial imidazolium compound that exists by being chemically bonded to a polymer chain so that antibacterial effect is maintained for a long time. A manufacturing process of the antibacterial coating is simple by inducing a thiol N bond using light irradiation, and a use of toxic organic solvents is unnecessary, thereby providing an eco-friendly antibacterial coating.
Abstract:
PURPOSE: A neutron focusing device for an ultra small neutron scattering apparatus is provided to prevent a reflection surface from being newly processed by controlling the curvature of a reflection curved surface to control a focus. CONSTITUTION: A focusing plate includes a plurality of unit focusing plates and a reflection curved surface. A driving module (340) symmetrically rotates the unit focusing plates around a transverse center line and controls the curvature of the reflection curved surface. A motor supplies a driving force to the driving module.
Abstract:
PURPOSE: A device and a method for measuring a backlash are provided to quantitatively measure the precision of the position control of a driving system affecting a product production in a precise control field in which a repetitive task is performed. CONSTITUTION: A device for measuring a backlash includes a monochromator (20), an analyzing device (40), a control unit (60), and a detector (70). The monochromator performs the Bragg diffraction of incident lights. The lights diffracted by the monochromator are incident into the analyzing device, and the analyzing device performs the Bragg diffraction of the incident lights. The control unit controls a driving unit connected to the monochromator or the analyzing device, thereby rotting the monochromator or the analyzing device in a first direction and a second direction opposite to the first direction. The detector detects the lights diffracted by or penetrated through the analyzing device while the monochromator or the analyzing device are rotated and measures a backlash of the driving unit by using the detected lights.
