摘要:
In a flat display panel, a surface of at least one of a sustain electrode and an address electrode may be formed to have a curved surface. The surface of the electrode may be formed as a continuous curved surface. The sustain electrode and the address electrode may be elongated in a lengthwise direction thereof. These lengthwise directions may be perpendicular to each other. The electrode may be formed by transferring an electrode material onto the substrate using an electrode frame defined with electrode forming grooves each having a same sectional shape as the electrode. Therefore, the surface of the electrode may be formed as the curved surface.

Disclosed herein is a vibration actuator. The vibration actuator excites a mass member by interaction between an electric field of a vibration coil provided in an inner space of a case and a magnetic field of a magnetic field unit disposed corresponding to the vibration coil. The vibration actuator comprises an elastic wire having a wire body fixed to the outer surface of the mass member and elastic ends fixed to the inner surface of the case. The elastic wire is connected between the case and the mass member for elastically supporting mass member. The present invention minimizes change of natural frequency due to manufacturing tolerance of raw materials to improve vibration characteristics of the vibration actuator, simplifies and reduces a manufacturing process to improve productivity of the vibration actuator, and improves durability to increase the service life of the vibration actuator.

The present invention relates to a boring machine having differential global positioning system receiver for underwater rock and boring method thereof, new boring technology—a satellite navigation device orients the accurate position of a target—is brought to the underwater boring technology. A differential global positioning system (DGPS) receiver is provided at the body of a boring machine that is installed at the central opening of a self elevation platform (SEP) barge, the location of the boring machine is set to concentricity of the target boring position, and the position of the hull can be controlled without any movement of the boring machine. Then, the barge quickly moves to the next target boring location owing to the operation of a hull moving means so that the construction efficiency of the boring work can be enhanced.

Disclosed are a silicon derivative, a liquid crystal composition comprising the same, and a compensation film for a liquid crystal display device using the same liquid crystal composition. More particularly, the silicon derivative is a liquid crystal material of a high-quality view angle compensation film, which improves a contrast ratio measured at a tilt angle when compared to a contrast ratio measured from the front surface and minimizes color variations in a black state depending on view angles.

A food container and refrigerator having the same are disclosed, by which a content accommodated in the food container is facilitated to be taken out of food container. The present invention includes a main body having an entrance on a topside of the main body, a cover opening or closing the entrance of the main body, and a locking unit having one side connected to the main body and the other side detachably engaged with an upper part of the cover to prevent the cover from being opened.
摘要:
A self-supporting air tube for blasting and method of blasting rock using the air tube. The air tube includes an air bladder, a pair of support wings and an inlet The air bladder has a diameter smaller than that of a blasting hole and extends longitudinally. The support wings extend from the outside of the air bladder symmetrically with respect to the longitudinal axis of the air bladder so as to surround the air bladder and have certain widths. The inlet is attached to the upper fusion-welded portion of the air bladder to inject air into the air bladder. The total diameter of the air tube is smaller than the diameter of the blasting hole, and the air tube is inserted into the blasting hole and self-supported on a wall of the blasting hole.
