Provided is a voltage-controlled oscillator (VCO) using a current feedback network for use in a wireless communication terminal. The voltage-controlled oscillator has high input impedance and low output impedance, so that a degree of isolation from the external load is excellent, thereby preventing degradation of the Q-factor by the load in overall oscillation circuit. In the voltage-controlled oscillator of the present invention, an LC resonator is provided to generate positive feedback, and negative resistance may be obtained at a wider frequency range by tuning a varactor of the LC resonator. And a boosting inductor is inserted into the positive feedback loop to have a greater negative resistance, therefore it is possible to prevent a problem in which the oscillation does not occur due to the parasitic resistance components generated during circuit fabrication.

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.

The present invention relates to a refrigerator. In the present invention, a communication pad 60 is installed in one of the doors 51 and 53 for opening and closing storage spaces formed in a refrigerator main body 50. The communication pad 60 is detachably installed in a seating; space 58 of the door 53. While an upper end of the communication pad 60 is seated in the seating space 58 by an upper clamp 61, a lower end of the communication pad 60 is seated in the seating space 58 by a lower clamp 61′. The upper clamp 61 and the lower clamp 61′ are installed in the seating space 58 through hinge assemblies 65. Here, the hinge assemblies 65 are configured so that the upper and lower clamps 61 and 61′ rotate only by a force of a predetermined value or higher. According to the present invention constructed as above, it is possible to get advantages in that the communication pad 60 is securely mounted to and easily dismounted from the door 53.
摘要:
An icemaker for an ice supply system for preventing water from overflowing from the ice tray by vibration and/or shaking of the surrounding structure includes an icemaker, a container provided at a lower part of the icemaker and an ice chute for supplying the ice stored in the ice container. An ejector in the ice tray of the icemaker and a dropper device having an inclined upper surface at a side of the open top of the ice tray are provided for dropping the ice discharged upwardly by the ejector. The dropper has no gap or slot through which the ejector passes to prevent water overflow through the dropper. An overflow prevention device is provided at another side of the open top of the ice tray for preventing water filled in the ice tray from overflowing.

Disclosed are a full ice level sensing apparatus and method in which a full ice level of ice cubes in an ice bank is sensed by means of upward and downward movements of an elevating member, thereby minimizing an operational area of the elevating member required to sense the full ice level and increasing an effective volume of a freezing chamber. The full ice level sensing apparatus includes an elevating member disposed so as to rectilinearly move up and down into the ice bank, elevating means for rectilinearly moving the elevating member upward and downward, and sensing means for sensing whether or not the ice bank is at the full ice level based on the position of the elevating member.

Provided are a system for generating a surface mesh surrounding particles on a 3D space. An implicit function module receives particle data containing three-dimensional location and radius data of the particles, grids the particles into rectangular parallelepiped shape, and generates implicit function data having implicit function value determining the surface at grid points. A mesh module generates a mesh through a pre-process of substituting the implicit function value of the gird point, where the implicit function value is defined, by zero when the a distance between a grid point where the implicit function value of the implicit function data and the vertex of the mesh is within a set distance. Accordingly, the system and method are useful for visualizing the results of particle simulations used in basic science and engineering. In particular, the system and method can generate high-quality mesh in computer graphics of fluid simulation using the particles.

The present invention is based at least in part on the discovery of a role for the JNK signaling pathway in longevity. In particular, the present inventors have shown that overexpression of c-jun N-terminal kinase 1 (jnk-1) extends lifespan and that said extended lifespan is associated with DAF-16 phosphorylation by JNK-1 and the consequent DAF-16 localization to the nucleus. Accordingly, the present invention features methods of identifying modulators of longevity in assays featuring organisms and/or cells having a JNK signaling pathway and, optionally, an IR signaling pathway. Also featured is an in vitro method of identifying an agent capable of enhancing longevity featuring an assay composition having a JNK signaling pathway molecule and insulin signaling pathway molecule. Further featured are therapeutic methods for the use of JNK signaling pathway modulators to enhance longevity, to prevent or reduce obesity and to prevent or treat type II diabetes.
摘要:
The present invention relates to a safety design and risk management of a reactor of a nuclear plant, and more particularly, to an ex-vessel core melt device preventing molten core concrete interaction, which is to handle very severe accidents caused by cooling-function loss to nuclear fuel. Due to the large quantity of nuclear fuel existing in the reactor and decay heat which is latent and continuously generated within the fuel mass for a long time after the nuclear chain reaction, the nuclear fuel is melted in gross at temperature up to 2,500 degrees centigrade, and thereby the surrounding structures and a reactor vessel are attacked and damaged, and in the end, a containment building floor is eroded. This situation may cause environmental radioactivity either by ultimate penetration of the cavity floor or by the buildup of non-condensable gas pressure (i.e., pressurizing the containment building structure), unless the reaction is arrested. The ex-vessel core melt retention device preventing molten core concrete interaction, which is installed for alleviating risks due to unexpected accidents over accidents considered as a design criteria of a nuclear plant, includes: horizontal jacket pipes located on a shell boundary of a cavity floor, the horizontal jacket pipes having water inlets A formed at their lower half in an appropriate density for allowing water to enter the bottom of the pipes; vertical pipes connected at both ends of the horizontal jacket pipes in the form of a dovetail to communicate with each other; and a water supply part located at the lower portion of the horizontal jacket pipes for allowing water to enter from the whole area of the bottom.
