A method for managing copy protection information of a recording medium is disclosed. A data stream encrypted using copy protection information is recorded in a data area of an optical disc such as a write once optical disc or a rewritable optical disc, while the copy protection information and a drive ID are recorded together in a key locker of the optical disc. When a data stream of an optical disc is reproduced, reading and decryption of the copy protection information is selectively performed depending on whether the drive ID recorded in the key locker and a drive ID managed in an optical disc drive, into which the optical disc is inserted, are identical. This prevents contents such as broadcast programs recorded in an optical disc from being illegally duplicated.

A drum washing machine, in which scale deposited in a steam generating device installed for improving sterilizing and washing capacities is efficiently eliminated. The drum washing machine includes a housing; a tub for containing washing water; a drum rotatably installed in the tub; and a steam generating device installed in the housing for supplying steam for sterilizing laundry to the drum, wherein a scale eliminating unit is installed in a water supply channel of the steam generating device, and includes at least one protrusion formed on the inner circumferential surface of the water supply channel or a water supply valve and a pulsation circuit for controlling the flow rate and amount of the water. The scale eliminating unit forms turbulence in the steam generating device or supplies water having varied flow rate and amount to the steam generating device, thereby efficiently eliminating scale deposited in the steam generating device.

A pole adaptor for connecting and disconnecting a multi-task pole with an attachment tool provides a secure connection and preserves the useful life of the multi-task pole. The adaptor embodies an elongated cylindrical housing having a first open end with two clip holes, a mid-section, and a second open end having four tab holes. The first open end forms a receptacle for the multi-task pole and an alignment with the clip holes for securely attaching the pole adaptor. The second open end forms a receptacle for the attachment tool handle and allowing the handle tabs to connect with two tab holes therein. Four tab holes are provided at the second open end for continued use of the adaptor if two tab wholes wear out.

Disclosed herein is a process for the preparation of dimethylether from hydrocarbons, including tri-reforming a feedstock mixture comprised of hydrocarbons, carbon dioxide and water vapor in the presence of a tri-reforming catalyst, to prepare a syngas, which then undergoes gas-phase direct synthesis into dimethylether in one step in the presence of a hybrid catalyst. According to the process of this invention, three main processes among typical syngas preparation processes are simultaneously performed, and then, the syngas thus obtained is prepared into dimethylether through a direct reaction in one step, thereby decreasing the apparatus cost and operation cost. In addition, all of the carbon dioxide separated and recovered from the unreacted material and by-products may be reused as reaction material, thus decreasing the generation of carbon dioxide and reducing the material cost.

A washing machine having a drying function, which includes a steam generating device for spraying steam directly onto laundry, and a method for controlling the same. The method for controlling the washing machine, which supplies hot air, heated by a drying heater, to laundry through a drying duct, includes heating supplied wash water to generate steam; spraying the generated steam onto the laundry through the drying duct to perform a washing operation; determining whether or not a drying operation after the washing operation is performed; and performing a dehumidifying operation such that a drying fan is operated to remove moisture remaining in the drying duct when it is determined that the drying operation is not performed, thereby improving washing capacity, reducing an energy consumption rate, and effectively removing the moisture remaining in the drying duct when the drying operation after the washing operation is not performed.
