20090106886 | Automatic hinge module and apparatus having the same for opening and closing toilet bowl - An automatic hinge module and apparatus for opening and closing a toilet bowl. The module includes: a motor, which generates a driving force; a housing, of which one end is coupled to a body of the motor; a drive shaft, which is rotatably coupled to the housing, and which has one end coupled to an output shaft of the motor, such that the centers of rotation of the drive shaft and the output shaft coincide, to allow the drive shaft to transfer the driving force to the exterior; and a spring, one end of which is coupled to the housing, and the other end of which is coupled to the drive shaft, such that the spring provides an elastic force to the drive shaft in a direction of rotation of the drive shaft. Using this module, the cover and seat of a toilet can be opened and closed automatically. | 04-30-2009 |
20090255090 | Hinge assembly and mobile terminal having the same - A hinge assembly and a mobile terminal are disclosed. The hinge assembly can include: a torsion spring; a shaft, which penetrates through the torsion spring; a bushing, coupled to one end of the torsion spring and to one side of the shaft; a holder, which is coupled to the other end of the torsion spring, and which the shaft penetrates through; a sliding cam, which is coupled to the other side of the shaft, and which may move in linkage with the shaft; a fixed cam, which engages the sliding cam; a compression spring, which is positioned between the holder and the sliding cam, and which may place the sliding cam in close contact with the fixed cam; and a housing coupled to the holder and the fixed cam. Thus, the mobile terminal can be unfolded automatically using just a few number of parts without requiring energy consumption. | 10-15-2009 |
20090255091 | Hinge assembly and mobile terminal having the same - A hinge assembly can include: a torsion spring; a shaft, which penetrates through the torsion spring; a bushing, coupled to one end of the torsion spring and one side of the shaft; a holder, which is coupled to the other end of the torsion spring; a housing coupled to the holder; and a damper, which is coupled to the shaft, and which may dampen a rotation speed of the shaft. The damper can include: a first case, which is coupled to the shaft to move in linkage with the shaft; a second case, rotatably coupled to the first case; a viscous fluid, placed between the first case and the second case; and a stopper, which is coupled to the housing and configured to restrict the rotation angle of the second case. Thus, a mobile terminal may be unfolded automatically using a few number of parts without requiring energy consumption. | 10-15-2009 |
20090282647 | HINGE ASSEMBLY AND MOBILE COMMUNICATION TERMINAL HAVING THE SAME - A hinge assembly and a mobile communication terminal equipped with the hinge assembly are disclosed. The hinge assembly in accordance with an embodiment of the present invention can include: a housing; a fixing cam, which is coupled to the housing and has a cam head and a ramp; a shaft, which is coupled to the fixing cam such that the shaft and the fixing cam can rotate; a torsion spring, which is coupled to the fixing cam on one end and the shaft on the other end; a sliding cam, which is coupled to the shaft, such that the sliding cam is allowed to slide over the shaft along the axial direction, and has a protrusion facing the ramp; and a compression spring, which is interposed between the sliding cam and the shaft such that the sliding cam is compressed toward the fixing cam. By using a cam structure, the present invention can selectively control the rotation of the hinge assembly. | 11-19-2009 |
20140186199 | ELECTRIC BLOWER - Disclosed herein is an electric blower including: an impeller; a driving module including a rotor part coupled to the impeller in order to driving the impeller and a stator part, the rotator part including a magnet and the stator part including an armature formed of a core positioned so as to face the magnet and a coil; a motor housing having the driving module mounted thereon; and a control module mounted on the motor housing and controlling the driving module. | 07-03-2014 |
20140369869 | ELECTRIC BLOWER - Disclosed herein is an electric blower capable of preventing grease stored in a boss part of a bracket from being leaked and/or evaporated. The electric blower includes: a housing receiving a stator, a rotating shaft, and rotor; a housing cover covering an upper opening part of the housing; and a bracket including a boss part which protrudes vertically upward in a cylindrical shape at a central portion thereof to receive an upper bearing and the rotating shaft and a flange which radially elongates outward from the boss part to be coupled with the housing and rotatably supporting the rotating shaft, wherein the boss part includes a disk-shaped flat upper surface having a shaft hole helping penetration of the rotating shaft, a cylindrical side wall extending downward from an edge of the upper surface, and at least one guide groove formed at a lower portion of the upper surface. | 12-18-2014 |
20150235666 | SPINDLE MOTOR AND RECORDING DISK DRIVING DEVICE INCLUDING THE SAME - There is provided a spindle motor including: a base member including an installation part extended upwardly in an axial direction and a coupling hole formed to be disposed around the installation part; a stator core including winding grooves into which a coil is inserted and wound therearound and protrusion parts formed on a surface opposite to a surface in which the wounding groove is formed, and fixedly installed in the installation part; and a strength reinforcing member including a concave groove formed therein so as to be disposed to face the protrusion part, and coupled to the coupling hole in order to reinforce strength of the base member. | 08-20-2015 |
20160055880 | SPINDLE MOTOR AND RECORDING DISK DRIVING DEVICE INCLUDING THE SAME - A spindle motor includes a base member including an installation member formed of a magnetic material, a sleeve fixedly coupled to a mounting part provided in the base member, a shaft rotatably installed in a shaft hole of the sleeve, a rotor hub installed on an upper end portion of the shaft to rotate together with the shaft, a driving magnet fixedly coupled to a lower surface of the rotor hub, and a coil fixedly coupled to the installation member so as to be disposed to face the driving magnet. | 02-25-2016 |
