Abstract: A display device includes a condition judgment unit which judges whether a received email satisfies a predetermined condition. Moreover, the display device includes a data deletion unit which deletes attached data in an email from a recording unit if the condition judgment unit detects that the email does not satisfy the predetermined condition. Moreover, the display device includes a condition registration unit which receives a condition for storing attached data. The condition registration unit receives a transmission source email address of an email which a user desires to store. When an email is received by the email reception unit, the condition judgment unit judges whether the transmission source email address coincides with a part or whole of the reception-enabled address. If yes, the attached data is stored. Otherwise, the data is deleted.

Abstract: A process for producing a fiber assembly or agglomerate requiring micropores, such as for a battery separator or any of various filters, which is performed by electrostatic spinning and provides high productivity and ease of maintenance, is provided. The process for producing a microfiber assembly or agglomerate by electrostatic spinning includes continuously forming bubbles on a polymer solution or a polymer melt and applying high voltage to the formed bubbles. The bubbles can be formed by passing compressed air through porous material of one or a combination of two or more of plastic, ceramic and metal materials, or capillaries.

Abstract: A plurality of program components, which do not have matching interfaces, are combined together automatically to generate a larger new program. An interface specifications' database registers the interface specifications corresponding to each of the program components. A program transformation rule memory stores transformation rules for controlling the reconciliation of the non-matching interface specifications of the program components. A data type memory stores data type transformation rules for reconciling non matching data specifications. A mediating program generator detects a mismatch of the interface specifications between at least two program components which are being combined and generates a mediating program in accordance with the program transformation rule and the data type transformation rule which mediating program enables the two programs and their data to communicate.

Abstract: The system providing a guidance for the command entry to an interactive computer recognizes the hierarchical rank of productions and displays command explanatory messages below the rank of production to which the command in need of explanation belongs. Displaying commands of one or two ranks relieves the operator from the annoyance of useless display reading.
