Abstract:
A cooker and methods of manufacturing and controlling the same. The cooker including a first coating layer that is a general ceramic enamel layer and a second coating layer that includes phosphorus oxide-based components are coated on a surface of a cavity corresponding to the inner surface of the cooking chamber. Therefore, the inside of the cooking chamber can be more easily cleaned.

Abstract:
The present invention relates to a medicinal composition for preventing or treating pancreatic cancer, comprising 3-alkoxy-6-allylthiopyridazine or a pharmaceutically acceptable salt thereof as an effective ingredient. An MTT assay, to assess the viability of cells, and flow cytometric analysis, to measure apoptotic cell death, were performed, and the results, which revealed that the compound and pharmaceutically acceptable salts thereof have preventive and therapeutic activity against pancreatic cancer, are presented herein.
Abstract:
An inkjet printhead including a passage plate in which a manifold to supply ink and a nozzle to eject ink are formed; a first electrode and a second electrode formed on the passage plate around the nozzle to generate an ion wind by ionizing air between the first and second electrodes by a voltage that is applied between the first and second electrodes, and a third electrode and a fourth electrode to generate an electrostatic force by a voltage applied between the third and fourth electrodes, wherein the third electrode is separated from the passage plate and the fourth electrode is formed on the passage plate.
Abstract:
The present invention relates to a bolometer, and more specifically to a compensation circuit for compensating non-uniformity due to the difference of operating temperature between bolometers which exist in bolometer array using semiconductor material. A compensation circuit according to the present invention comprises a biasing part including a first transistor generating bias current according to the change of operating temperature to have a dependency of exponential function for the operating temperature of circuit, and a second transistor turned on/off according to the column signal of a bolometer array; a bolometer part including a variable resistor for detecting IR in a pixel base, a third transistor turned on/off according to the column signal of a bolometer array coupled to one end of the variable resistor, and a fourth transistor turned on/off according to the row signal of a bolometer array coupled to the other end of the variable resistor; and an off-set compensation part for compensating the non-uniformity of the bolometer unit.
Abstract:
A thermally-driven ink-jet printhead includes a substrate having an ink chamber to be filled with ink to be ejected, a manifold for supplying ink, and an ink channel for providing flow communication therebetween. First and second sidewalls are formed to a predetermined depth from an upper surface of the substrate and define the ink chamber to have a substantially rectangular shape. A nozzle plate including a plurality of material layers is formed on the substrate. A nozzle passes through the nozzle plate and is in flow communication with the ink chamber. A heater is disposed between the nozzle and one of the first sidewalls above the ink chamber. A conductor is electrically connected to the heater. The conductor and the heater are disposed within the nozzle plate. A shifting feature moves cavitation points beyond an outer edge of the heater.
Abstract:
A magnetron includes an anode having an anode cylinder and anode vanes; a cathode having a filament; a condenser, a choke coil, and a plurality of leads for providing power to the filament; a plurality of magnets, pole pieces, and a yoke for forming a magnetic circuit; an antenna feeder and an antenna cap for transmitting a generated microwave outside of the magnetron; and a plurality of joints formed of a joining material between a metal component and a ceramic component of the magnetron. The joining material is diffused between the metal component and the ceramic component, to infiltrate into an inner part of the ceramic component directly, thereby joining the metal and ceramic components, and thereby also improving a reliability of a magnetron, facilitating a simple component assembly process and a simple magnetron fabrication process, permitting simplification of the fabrication process and reduction of a fabrication cost, and saving equipment cost as a high temperature furnace can be dispensed with.
Abstract:
A video repeat reproduction method and apparatus for use with a video recording and reproducing apparatus such as a video tape recorder, which employs predetermined signals to repeatedly reproduce a specific interval of a video signal. The method includes the steps of recording distinctive index signals respectively at the starting point and ending point of a desired repeat reproduction interval while displaying a reproduced picture, detecting the index signals which are recorded on the recording medium, displaying the detected index signals on a screen, and repeatedly reproducing the interval of the video signal on which the index signals have been recorded by a desired number of times if a repeat reproduction command is applied.
