Abstract: A microwave oven including a component chamber penetrating part fluidly communicating with a component chamber, a cooking chamber penetrating part fluidly communicating with a cooking chamber, a discharging part discharging air within the cooking chamber through the cooking chamber penetrating part, and a fan assembly, including an inhaling fan ventilating the air into the component chamber penetrating part so as to cool the component chamber, a discharging fan ventilating the air within the cooking chamber into the discharging part through the cooking chamber penetrating part, and a fan motor provided between and driving the inhaling fan and the discharging fan. A detachment preventing part is provided on an inhaling fan cover and/or a discharging fan cover to prevent either of these covers from being detached from the fan assembly.

Abstract: A microwave oven including a component compartment and a cooking compartment each including a discharging part to discharge air in the cooking compartment through the cooking compartment through portion; a supplying fan introducing the air to the component compartment through portion to cool the component compartment; a discharging fan introducing the air in the cooking compartment to the discharging part through the cooking compartment through portion; a fan motor between the supplying fan and the discharging fan to operate the supplying fan and the discharging fan; and an interfering part to interfere with the fan assembly when at least one of the supplying fan and the discharging fan is not in a predetermined position corresponding to the component compartment through portion and the discharging part.

Abstract: A microwave oven including: a main casing forming a component compartment and a cooking compartment and formed with a component compartment through portion communicating with the component compartment; a fan assembly coupled to the main casing, and including an exhaling fan blowing air toward the component compartment through portion to cool the component compartment and a fan motor driving the exhaling fan; and a guide unit mounted to the component compartment through portion and guiding the air blown by the exhaling fan toward a heating component accommodated in the component compartment.

Abstract: The present invention relates to a wall-mounting type microwave oven including a main body, a bottom plate provided on a bottom portion of the main body and having an opening, and a lamp supporter to support a lamp provided in the opening. The bottom plate being integrally formed with the lamp supporter to support the lamp. Thus, the lamp installation structure is simplified and the number of components is decreased.

Abstract: A device to cool an integrated circuit element, the device having a printed circuit board with a through hole smaller than the integrated circuit element; a cooling pad attached to a first element surface of the integrated circuit element, and positioned inside the through hole; and a heat transfer portion connected with a heat absorption body and making contact with the cooling pad, to transfer heat to the heat absorption body, so that the integrated circuit element is cooled by transferring the heat generated in the integrated circuit element, which is mounted on a first surface of the printed circuit board, to the heat absorption body, which is disposed facing a second surface of the printed circuit board opposite the first surface.

Abstract: Disclosed is an apparatus for creating visual power of a blind person, who has lost a visual ability due to various reasons, thereby recovering the visual ability of the blind person. The visual power creating apparatus includes a CCD camera for picking up the image of an object, a TFF LCD monitor for displaying the image picked up by the CCD camera, a light source for illuminating the TFT LCD monitor at the rear side of the TFT LCD monitor and adapted to increase the illuminance of the image displayed on the TFT LCD monitor, a control box for supplying electric power to the CCD camera and the TFT LCD monitor and transmitting the image from the CCD camera to the TFT LCD monitor via an image transmission line, and an optical system for enlarging the image displayed on the TFT LCD monitor to the actual size of the object.

Abstract: A non-contacting measuring method for three dimensional micro pattern in a measuring object is disclosed. Three dimensional micro pattern of the surface of the measuring object is measured using blur of light. For measurement, a mechanism of an optical window with a slit is inserted between light source and the measuring object. The blurred image is captured by charge coupled device sensor based image frame grabber, and is analyzed in personal computers. All the values of the relative height differences are obtained in overall scanning measurement area of the measuring object. The relative height differences are the distances from the reference position to the other positions. The reference position is selected when its image is sharp in focus on the screen. At this time, images of the other positions except the reference position are blurred out of focus on the screen.
