Abstract:
Disclosed is an antifoaming agent for vinyl chloride resin slurry. The agent of the present invention may prevent generation of Fish eyes and deteriorate in production efficiency caused by slurry foams without inhibiting inherent transparency of vinyl chloride resins, in the process of preparing the vinyl chloride resins by polymerizing a monomer mixture containing vinyl chloride as a main component in a polymerization reactor.
Abstract:
The present invention provides a horizontal linear vibrator which can reduce the thickness but increase vibration strength while at the same time guaranteeing a sufficiently long lifetime and satisfactory responsivity. The horizontal linear vibrator includes a casing, a bracket, a vibration unit and springs. The casing defines an internal space therein. The bracket is disposed under the casing. A cylindrical coil is provided on the bracket. The vibration unit has a magnet, a yoke and a weight. The yoke contains the magnet therein and is open on the lower end thereof. The weight is coupled to the outer surface of the yoke. The springs are coupled to sidewall plates of the casing or the bracket. The springs elastically support the vibration unit to allow the vibration unit to vibrate in the horizontal direction.
Abstract:
A mobile terminal including a metal case and an antenna structure that can exhibit optimum radiation performance is provided.

The supporting device to the display apparatus includes a plurality of support protrusions coupled to a rear surface of the display apparatus, a plurality of first support panels fixed to the wall, and a plurality of second support panels rotatably coupled to the first support panels, respectively, each second support panel having a receiving region by which a corresponding one of the plurality of support protrusions is received.
Abstract:
A structure of engine mounting for supporting a pitch axle in a vehicle may include a front roll mount and a rear roll mount arranged on the pitch axle passing through a powertrain's center of gravity; wherein the weight of an engine is shared by the front roll mount and the rear roll mount.
Abstract:
The present invention provides a horizontal linear vibrator which can reduce the thickness but increase the strength of vibrations while at the same time guaranteeing a sufficiently long lifetime and satisfactory responsivity. The horizontal linear vibrator includes a casing, a bracket, a vibration unit and springs. The casing defines an internal space therein. A first magnet is attached to an upper plate of the casing. The bracket is coupled to the lower end of the casing. The second magnet is attached to the bracket such that different poles of the first and second magnets face each other. The vibration unit has a weight, and a cylindrical coil which is provided in or under the weight. The springs are coupled to the sidewall plates of the casing or the bracket. The springs elastically support the vibration unit to allow the vibration unit to vibrate in the horizontal direction.
Abstract:
Disclosed herein is a linear vibration motor. The motor includes a casing surrounding the top and widthwise side of the motor, and a bracket surrounding the bottom and lengthwise side of the motor. A plate is provided on an inner surface of a side of the bracket and integrally has a cylindrical part to accommodate a coil. A mass body is provided in a central portion of the bracket and vibrates horizontally, a yoke is provided on a side surface of the mass body, and a magnet is mounted to a central portion of the yoke to be inserted into an internal space of the coil. A spring couples the plate with the yoke, thus transmitting vibratory force to the motor. An extension part extends from an end of the spring, and a bearing is provided on an end of the extension part, thus minimizing friction with the casing.
Abstract:
Provided is a packing means for sealing including a base ring member; an upper ring member; and a lower ring member, wherein the base ring member has a projection line at the inner surface thereof so as to be not slide on an outer surface of the pipe but fixed thereon when the base ring member is closely contacted with the upper and lower ring member at the same time when being rotated by external force, and also has a rib line which is formed to traverse the projection line so that a depth that the projection line is struck into the outer surface of the pipe is restricted, and the projection line is formed into a spiral or oblique-toothed structure so as to be struck in a desired depth into the outer surface of the pipe toward the lower ring member corresponding to the upper ring member.
Abstract:
An antenna device for shifting a resonance frequency including an antenna pattern having a first resonance frequency and a magnetic body disposed within a predetermined distance of or contacting with one side of the antenna pattern for shifting the first resonance frequency to a second resonance frequency. When the first resonance frequency of the antenna pattern is shifted to the second resonance frequency, radiation efficiency is not reduced.
Abstract:
There is provided a vibration motor including: a housing having one open surface; a permanent magnet disposed in an internal space of the housing and interacting with a coil to generate electromagnetic force; an elastic member formed in the housing; a mass member coupled to the elastic member to perform resonant movement through the electromagnetic force; a cover covering the one open surface of the housing; and an extension part extended from the one open surface of the housing in a height direction thereof and compressed with the cover to closely attach the housing and the cover to each other.
