    摘要： Disclosed herein are an inverter microwave oven and a method for controlling the same, wherein a switching frequency of an inverter is raised during the initial operation of the microwave oven and then lowered during the normal operation of the oven after the lapse of a predetermined time, so as to prevent overvoltage from being applied to a magnetron, which generates electromagnetic waves, during the initial operation, thereby enhancing durability and operational reliability of the inverter. The inverter microwave oven comprises a rectifier for rectifying and smoothing a commercial AC voltage into a DC voltage. The inverter is adapted to perform a switching operation based on the DC voltage from the rectifier to generate a magnetron drive AC voltage. The microwave oven further comprises a magnetron driver for converting the AC voltage from the inverter into a high-power DC voltage and applying the converted DC voltage to the magnetron, and an inverter control unit for varying the switching frequency of the inverter to prevent overvoltage from being applied to the magnetron.

    摘要： An ink composition for roll printing is provided. The ink composition uses a solvent system having an evaporation rate (Vt) of at least 0.1 mg/cm2·min and an absorption rate (St) into a blanket of less than 3.412 mg/cm2·min. The use of the highly volatile solvent system can minimize swelling of the blanket without impairing the dispersibility of a pigment in the ink composition. Therefore, the uniformity of a pattern formed using the ink composition can be maintained and the formation of defects by the solvent system can be minimized.
