Abstract: PURPOSE: A piezoelectric inverter for preventing a leakage current is provided to minimize a leakage current due to a parasitic condenser and attain uniform brightness of a cold cathode tube by connecting two terminals of the cold cathode tube to an input and an output of a transformer. CONSTITUTION: A transformer(21) amplifies a current supplied from an input to a predetermined rate. A cold cathode tube(22) connects each terminal to reduce a leakage current on an input and an output of the transformer(21) and generates light by virtue of an electron discharging phenomenon of a current which is transferred from the output of the transformer(21). A feedback part(23) is connected to either of two inputs of the transformer(21), senses a current flowing the cold cathode tube(22) to transfer a constant amount of current to the cold cathode tube(22), and performs control and output actions according to the sensed amount of current. A switching control part(24) determines whether a power is supplied to continuously drive the system by the amount of current output by the feedback part(23) and output a switching control signal. A switching part(25) allows a switching element to be operated on/off to supply the power to the system according to the switching control signal. An inductor(L) transfers the current transmitted from the switching part(25) to the transformer(21).

Abstract: Data (D), which has been coded by a coder (COD) so as to obtain coded data (CD), is modified. The data (D) may be, for example, a sequence of pictures which has been coded in accordance with an MPEG standard. The data (D), which is available in a coded form, is modified in the following manner. A partial decoder (PDEC) partially decodes the coded data (CD). That is, of a series of decoding steps (Sd(1)..Sd(N)) which need to be carried out in order to decode the coded data (CD), the partial decoder (PDEC) carries out only a first few decoding steps (Sd(1)..Sd(K)), with K and N being integers and K being smaller than N. Accordingly, partially decoded data (PDD) is obtained. A data-modifier (MOD) modifies the partially decoded data (PDD). Accordingly, modified partially decoded data (MPDD) is obtained. A complementary coder (CCOD) complementary codes the modified partially decoded data (MPDD). That is, the complementary coder (CCOD) carries out one or more coding steps (Sc(K)..Sc(1)), each of which is a complement (C) of a specific decoding step (Sd) which has been carried out by the partial decoder (PDEC). Accordingly, coded modified data (CMD) is obtained. Since only a partial decoding is carried out, fewer circuitry will be required than if the data (D) to be modified were fully decoded. Thus, the data (D) can be modified in a cost-efficient manner.

IPC: F25D25/02
Filed: 2000-03-10
Abstract: PURPOSE: A beverage can is provided to achieve a simplified structure and cooling efficiency by controlling foam and internal pressure caused by the reaction product generated through an endothermic reaction. CONSTITUTION: A self-cooler(1) is arranged inside of a beverage can, wherein the self-container has a lower end serving as a chemical material reservoir(2) containing chemical materials for endothermic reaction. The self-cooler has a ring(3) arranged at the top of the self-cooler, and which forms a through hole(4), and removes the lower end of a water reservoir(5) and a baffle screen(6), when pulled. The water contained in the water reservoir flows into the chemical material reservoir through a passage pipe(7), and reacts with the chemical materials in the chemical material reservoir. Carbon dioxide and foam generated from such chemical reaction increase pressure in the chemical material reservoir, and shift to the water reservoir through a foam passage pipe(8). Subsequently, only the carbon dioxide is discharged from the water reservoir to outside through the through hole by a membrane(9) which discharges only gases. The residual water flows toward the chemical material reservoir through the passage pipe by the increased pressure in the water reservoir. The water reservoir has a slope inclined bottom plane for a smooth water flow, and the chemical material reservoir has a conical top so as to collect the carbon dioxide and foam generated during chemical reaction, thus increasing maximally internal pressure at the lower end portion of the chemical material reservoir and maintaining smooth water flow.
