A chemical etching solution in the form of jets under pressure is put into contact with the radioactive substance fixed on the surface inside the hollow body, and the chemical etching solution that has come into contact with the radioactive substance is recovered and drained to outside the hollow body. The actuators are spaced to allow them to extend rearwardly on opposite sides of the trigger guard. The apparatus includes a third circuit of the second type to couple the output node to a second power supply node in response to a second value of the first signal. Since the transaction right is generated on the basis of the attribute of the digital content item, or in other words, the transaction right is dependent on the attribute of the digital content item, the generated transaction right of digital content items can be different if the corresponding attribute associated with the digital content items are different. A second dielectric layer is formed over the circular cylindrical holes by a non-conformal chemical vapor deposition and sublithographic cavities are formed on the fuselink. The device driver receives a call requesting whether an interrupt received from a device is from the associated device and reads interrupt status information in memory within the computer to determine whether the associated device transmitted the interrupt, wherein the device writes the interrupt status information to the memory.
