    摘要: A two-piece collimator for use in high takeoff angle energy dispersive spectroscopy (EDS) is provided. The two-piece collimator includes a base section and an extension section. The collimator base section may be attached rigidly to the end of an EDS detector tube. The collimator extension section is removably attached to and extends from the base section. Apertures through the base and extension sections are easily aligned with each other and with an EDS detector. The length of the collimator extension section is preferably selected such that the distal end of the extension section extends below the bottom of an upper pole piece of an electron microscope in which the collimator is employed. A two-piece collimator in accordance with the present invention effectively reduces stray radiation, including back scattered electrons, which may cause artifacts in a detected EDS X-ray spectrum. Alternatively, a collimator in accordance with the present invention may be used in combination with an existing pole piece insert collimation device by removing the extension section from the two-piece collimator.

    摘要: The loss of data stored in a secure memory card, such as a SIM card, due to the physical destruction thereof is prevented. A host unit performs card authentication of a memory card, and transmits update data for the memory card by security communication to update data when the result of the authentication is OK. Then, the host unit outputs a request for mirror-updating the card data to a base station server. When an access is permitted, the card data is transmitted to the base station server via the host unit to mirror-update the card data. When the mirror-updating of the card data is completed, the base station server returns a completion confirmation to the host unit, so that a data backup process is completed. By thus causing the base station server to mirror-update the data in the memory card, the loss of the stored data is prevented.
