摘要： A method and a device are disclosed with which high-temperature combustion is attained using a fuel and an aqueous solution of an organic compound, e.g., an aqueous alcohol solution. In a combustion chamber, a fuel is sprayed and burned with a first burner to elevate the interior temperature of the combustion chamber (and/or a heat-resistant reflector disposed inside the combustion chamber) to a high temperature of 700° C. or above, and an aqueous solution of an organic compound (e.g., an alcohol-water mixture) is subsequently sprayed with a second burner into the high-temperature combustion gas obtained with the first burner, thereby causing microexplosion of water vaper and further elevating the interior temperature. As such, the fuels and organic compounds (e.g., Alcoholic aqueous solution) are fully burned, and thus the fuel cost can be reduced. Thus, high-temperature superheated steam containing a large amount of water vapor is yielded.

摘要： A method for ejecting a molded product from a die. The method includes advancing an ejector pin from a withdrawn position to a projected position for ejecting a molded product and withdrawing the ejector pin from the projected position to the withdrawn position. At a preset range in at least one of the advancing step and the withdrawing step, the ejector pin undergoes very small reciprocating movements having a period less than 0.1 seconds. When the ejector pin is advanced while very small reciprocation is performed over a preset range in the advancing step, energy due to the projection of the ejector pin is continuously and gradually dissipated. When the ejector pin is withdrawn while very small reciprocation is performed over a preset range in the withdrawing step, the molded product is easily separated from the ejector pin. Accordingly, scattering of molded products and generation of cracks in the molded products can be prevented. Also, the molded product is prevented from being placed back into the cavity. Further, a dwell step may be provided in which the ejector pin is maintained at its projected position while being subjected to very small reciprocation having a period shorter than 0.1 seconds.
摘要翻译：一种从模具中喷射成型品的方法。该方法包括将推出销从撤回位置推进到用于弹出模制产品的突出位置，并将顶针从突出位置撤回到撤回位置。在前进步骤和退出步骤中的至少一个中的预设范围内，顶针经历非常小的往复运动，其周期小于0.1秒。当在前进步骤中在预定范围内执行非常小的往复运动时，顶推销前进，由于顶针的投影引起的能量不断地逐渐消散。当在退避步骤中在预设范围内进行非常小的往复运动时，顶出销被拉出，模制产品容易与顶针分离。因此，可以防止模制品的散射和模制产品中的裂纹的产生。此外，防止模制产品被放回到空腔中。此外，可以提供停留步骤，其中顶针保持在其突出位置，同时经受小于0.1秒的非常小的往复运动。
