  • Patent number: 9739080
    Abstract: Provided is a device for opening and closing a sliding door, of which collinearly placed doors slide respectively to overlap each other such that the sliding door is opened or closed. The device includes a sliding portion formed on a surface on which doors come into contact with each other in order to prevent the doors from interfering with each other when the doors are opened; a pair of rail frames formed on a top surface of the furniture and provided with a rail protruding upwardly such that each door is slid forward and backward on the rail, the rail having both sides in which bending portions are formed; and rotational members, each of which is installed to one side of a connection bracket to be rotatable in a curved section of the bending portion while being lifted and slid on the rail.

  • Patent number: 9133143
    Abstract: The present invention relates to (3-fluoro-2-hydroxy)propyl-functionalized aryl derivatives or to the pharmaceutically acceptable salt thereof, to a method for preparing same, and to a pharmaceutical composition containing same as active ingredients for the diagnosis or treatment of neurodegenerative brain diseases. The aryl derivatives of the present invention are (3-fluoro-2-hydroxy)propyl-functionalized to increase the polarity thereof, and therefore the drugs containing the aryl derivatives can easily permeate into the cerebrovascular membrane, thus increasing the effectiveness of the drugs. As the aryl derivatives of the present invention strongly bind to ?-amyloid, the aryl derivatives, when labeled with radioisotope, can be used as a diagnostic agent for non-invasively diagnosing early Alzheimer's disease.

  • Patent number: 8497260
    Abstract: 2-arylbenzothiophene derivatives or pharmaceutically acceptable salts thereof, a preparation method thereof, and a pharmaceutical composition for the diagnosis or treatment of degenerative brain disease containing the same as an active ingredient. Since the 2-arylbenzothiophene derivatives of Formula 1 have a relatively high binding affinity for ?-amyloid, they can be used as diagnostic reagents for diagnosing Alzheimer's disease at an early stage by non-invasive techniques when they are labeled with radioisotopes: wherein R1-R4, V, W, X, Y and Z are as defined in the Detailed Descript of the specification. Further, when the pharmaceutical composition containing the 2-arylbenzothiophene derivative binds with a low-molecular weight ?-amyloid peptide binding compound, generation of malignant high-molecular weight ?-amyloid deposits is minimized. Accordingly, the pharmaceutical composition can be used as a therapeutic agent of degenerative brain disease such as Alzheimer's disease.

  • Patent number: 7698932
    Abstract: The present invention provides a device for measuring uneven wear of starter brushes for a vehicle which can accurately measure and compare the lengths of the starter brushes and easily determine whether or not eccentricity of an armature occurs, the device comprising: a hollow support; a receiving plate formed integrally with the outer circumferential surface of an upper portion of the hollow support to accommodate a plurality of brushes; a lifting body liftably inserted into the inside of the hollow support; a plurality of detection rods slidably connected to the outer circumferential surface of an upper portion of the lifting body and moving forward or backward toward the brushes; a lift driving means for driving the lifting body; a plurality of measuring sensors for measuring the lengths of the brushes by means of the detection rods; and an LCD panel for displaying the measured lengths; and a control unit for controlling the lift driving means, the measuring sensors and the LCD panel.

  • Publication number: 20080141857
    Abstract: Disclosed herein is an air conditioner compressor for a vehicle, which comprises a friction member mounted replaceably on the inner wall of the cylinder bore in which the piston reciprocates so as to come in contact with the friction member. The present air conditioner compressor may further comprise a spring member disposed between the outer circumferential surface of the friction member and the inner wall of the cylinder bore. The present invention provides an advantage that it is possible to remanufacture worn cylinders simply by replacing friction members.
