    • A method for controlling a cogeneration system is disclosed. The control method determines whether or not the operation load or power load of an air conditioner corresponds to a load requiring driving of a generator, controls the generator to operate when it is determined that the operation load of the air conditioner corresponds to the generator driving load, controls the air conditioner to operate using electric power generated from the generator when the generator operates normally, and controls the air conditioner to operate using commercial electric power when the operation load of the air conditioner is not the generator driving load or when the generator operates abnormally. Accordingly, there are advantages in terms of economy and safety.

    • A bubble-jet type ink-jet printhead has a structure in which a base plate, a barrier wall, and a nozzle plate are stacked. The base plate includes a substrate on which a recess is formed to a predetermined depth, an adiabatic layer formed on the substrate, a heater which is formed on the adiabatic layer and generates a thermal energy, and a passivation layer which is formed on the heater and passivates the heater. The barrier wall is stacked on the base plate, defines an ink chamber, which is disposed on the recess and has a recessed bottom surface, and defines an ink passage which communicates with the ink chamber. The nozzle plate is stacked on the barrier wall, has nozzles through which ink is ejected, and is formed at a location corresponding to a center of the ink chamber. Since a height of the barrier wall surrounding the ink chamber is reduced by the recess, delamination caused by ink soaked into the barrier wall can be prevented, and print performances such as a traveling property in a straight direction of ink droplets and ejection velocity of ink droplets, are improved.
    • 气泡喷墨式喷墨打印头具有堆叠基板,阻挡壁和喷嘴板的结构。 基板包括基板,其上形成有预定深度的凹部,在基板上形成的绝热层,形成在绝热层上并产生热能的加热器,以及形成在加热器上的钝化层 并加热加热器。 阻挡壁堆叠在基板上,限定了一个墨水室,它设置在凹槽上并具有凹入的底面,并且限定了与墨水室连通的墨水通道。 喷嘴板堆叠在阻挡壁上,具有喷嘴,墨通过喷嘴喷射,并且形成在与墨水室的中心对应的位置。 由于凹部围绕墨水室的阻挡壁的高度被凹部减小,因此能够防止由墨水浸透到阻挡壁中的墨分层,并且墨滴直线方向的行进特性和墨滴的喷射速度等打印性能 液滴,改进。

    • A microwave oven has a main body including a cooking compartment, and a component compartment in which a heating component is installed. An outer casing encloses the main body. A fan is provided at the component compartment corresponding to the heating component, and blows outside air to cool the heating component. An air inflow part is formed on the outer casing adjacent to the fan and through which the air from the cooling fan flows. A partitioning wall of a round shape separates the cooking compartment and the component compartment, wherein the fan is inclined with respect to the cooking compartment so that the air flowing through the air inflow part is guided toward the heating component along the partitioning wall.
