| 20120024828 | METHOD OF HYBRID WELDING AND HYBRID WELDING APPARATUS - There are provided a laser diode, an irradiating section that applies an output from the laser diode to a base material in the form of a laser beam and thus melts the surface of the base material while moving the laser beam; a wire feeding section that continuously feeds welding wire to a melted portion of the surface of the base material moving along with the movement of the laser beam emitted from the irradiating section; and a wire heating power source that electrifies the welding wire so that the welding wire located in the melted portion of the base material surface is almost melted. In the case of thick plate welding, it is possible to improve operating efficiency and working accuracy, and in the case of welding a hard-to-weld material such as a high-tensile steel board, it is possible to perform welding while preventing deterioration and fracture of metal structure from occurring. | 02-02-2012 |

| 20080285327 | Ferroelectric Memory and Semiconductor Memory - A chain type ferroelectric random access memory has a memory cell unit including ferroelectric memory cells electrically connected in series to each other, a plate line connected to an electrode of the memory cell unit, a bit line connected to the other electrode of the memory cell unit via a switching transistor, a sense amplifier which amplifies the voltages of this bit line and its complementary bit line, and a transistor inserted between the switching transistor and the sense amplifier. A value, being the minimum value of the gate voltage in the transistor obtained during elevation of the plate line voltage and comparative amplification, is smaller than a value, being the maximum value of the gate voltage in the transistor obtained during fall of the plate line voltage and comparative amplification. With these features, decrease in the accumulated charge of polarization in the memory cell is reduced and occurrence of disturb is prevented during read/write operations. | 11-20-2008 |
