    Abstract: A microwave oven includes a power supplying part, a cooking chamber, a door of the cooking chamber, a magnetron, and high and low voltage generating parts supplying voltage to the magnetron, further including: a door switch installed on branch lines of a power line toward the high and low voltage generating parts, operating depending on opening and closing the door and selectively connecting the power supplying part with the high and low voltage generating parts; a power saving switch controlling a connection between the power supplying part and the low voltage generating part; and a controller switching off the power saving switch when a predetermined time elapses after the magnetron stops operating. With this configuration, in the microwave oven, a power saving function can be automatically selected, and automatically suspended when the door is opened.

    Abstract: A microwave oven includes a compartment in which a magnetron and a high-voltage transformer are disposed. The transformer includes coils disposed within a core. The core has holes formed in its underside, which are aligned with respective through-holes formed in a bottom panel of the compartment. Bolts extend upwardly through the through holes and into the holes to secure the transformer directly to the bottom panel.

    Abstract: The present invention relates to a method of configuring a sensor pattern that linearly detects touch signals based on changes in the active area when a pen touches the ODA that constitutes the object detection device of the present invention installed on the conductive surface. It also pertains to a method of constructing a sensor pattern that minimizes moiré interference with the display device. As a result, the readability of pen-written characters is enhanced, and visibility is improved due to moiré avoidance.

    Abstract: The present invention involves replicating the existing state in a system to store in memory for detecting variations due to added factors. Based on the stored values in the memory, changes in the system are detected. A certain electronic circuit is used to extract these replicated values, and the values output from the electronic circuit are fed back. The adjusted input variables are then extracted and stored in memory.

    Abstract: The present invention involves driving multiple capacitors, including a shielding capacitance (Cin_sd), to minimize voltage fluctuations detected on the CDA signal line 200, thereby enhancing the resolution of the ADC. The additional capacitance (Cobj) generated between the CDA 100 and the object 20 due to the appearance of the object 20 is detected in the form of voltage. By analyzing with an ADC of improved resolution, it is possible to detect the presence of the object 20 more reliably.

    Abstract: Provided is a touch cell structure for a touch panel in which a touch cell is configured into a new pad to gate mode in order to solve a problem of a conventional capacitive-type touch input device. The touch cell structure includes: a conductive pad that forms an electrostatic capacitance with respect to a touch unit when a finger of a human body or the touch unit having an electrical characteristic similar to the finger approaches the conductive pad within a predetermined distance; and a three-terminal type switching device whose gate terminal is connected with the conductive pad and whose output signal is changed in correspondence to a change in electric potential of the gate terminal of the three-terminal type switching device by the electrostatic capacitance between the touch unit and the conductive pad. Since the potential of the gate terminal of the switching device is determined by an electrostatic capacitance formed in the conductive pad, a difference of the output signal output from the switching device becomes large depending on whether a touch input occurs or not.
