  • Publication number: 20070173108
    Abstract: An electronic apparatus having a cable connector unit that makes it possible to attach and detach a connector for connecting a cable for the purpose of performing data communication with an external apparatus includes a lock mechanism for maintaining a connection with the connector in a lock state. The electronic apparatus is capable of detecting a predetermined specific operation on the attached connector. If the specific operation is detected, then pre-processing necessary to detach the connector safely is executed. By releasing the lock mechanism in response to completion of pre-processing, the cable can be removed.

  • Publication number: 20060098775
    Abstract: An X-ray detector for drive timing setting is provided outside an image taking region of a sensor unit. Thus, an X-ray image taking device is constructed such that a case structure is simple and a preferable image which is not affected by back-scattering can be captured.

  • Patent number: 5618345
    Abstract: A self-supporting thin film of silicon single crystal is produced essentially by the steps of implanting boron ions in a silicon single crystal substrate from one major surface thereof to form a high impurity concentration layer having a high boron concentration in the substrate; heating the silicon single crystal substrate formed with the high impurity concentration layer in an atmosphere containing oxygen to form an oxide film on the surface of the single crystal substrate and make the high impurity concentration layer resistant to etching; masking all of the oxide film surface other than that at the center region on the surface opposite from that implanted with boron ions and then exposing the high impurity concentration layer by high-speed mask etching followed by selective etching; and removing the oxide film.
