Abstract: The present invention addresses the problem of evaluating the hydrophobicity of a powder. According to the present invention, a powder is charged into a mixed solvent composed of a lipophilic solvent and a hydrophilic solvent, the voltage rate R of the mixed solvent is measured at predetermined time intervals while adding a lipophilic solvent to the mixed solvent charged with the powder, a parameter x correlating with the concentration of powder is defined for an arbitrary voltage rate R, a continuous function HP(x) of the ratio of a lipophilic solvent corresponding to x is defined, and HP(x) for required x is set as a representative value of a lipophilic solvent ratio distribution and used as an index of hydrophobicity.

Abstract: A first terminal constituting an image sharing display system shares an image with a second terminal constituting the system. Display area information is transmitted from the second terminal. In the first terminal, which portion of the shared image is currently displayed on the second display screen of the second terminal is displayed on a first screen, as a frame-like pointer, on the basis of the display area information.

Abstract: A method for distributing and collecting an address information includes: transmitting an address information acquisition command from an originating terminal to a reception terminal, the address information acquisition command attached with an address information containing a group identifier of the originating terminal; registering the address information transmitted from the originating terminal in an address book provided in the reception terminal; searching the address book provided in the reception terminal for address information containing a group identifier that is same as the group identifier contained in the address information transmitted from the originating terminal; transmitting the address information found in the searching from the reception terminal to the originating terminal; and registering the address information transmitted from the reception terminal in an address book provided in the originating terminal.
