The present invention provides an electronic business card processing device and an electronic business card processing method which can effectively utilize information relating to electronic business cards. A business card is displayed on a display on the basis of stored information. When a cursor is positioned on the displayed business card, a tool bar is displayed on the displayed business card. The tool bar has one or a plurality of buttons. By using information unique to the displayed business card, processing corresponding to a selected button is executed. In another embodiment, in response to positioning of the cursor of the pointing device on a predetermined text field of the business card, a selectable tag is displayed on the displayed business card. An application program associated with the selected tag is started, and the information unique to the text field on which the cursor has been positioned is supplied to the started application program.
摘要:
A hierarchical address book for an organization is implemented where employees are represented by user objects and departments are represented by department objects. Computer-readable media include executable instructions for displaying and navigating the hierarchical address book. Computer-readable media also include executable instructions for ordering a list of recipients of an electronic mail message as a function of the seniority rating of an object in the hierarchical address book.
摘要:
A continuous polymerization process for producing reactive polymers comprises continuously charging into a first reaction zone at least one functional monomer and polymerizing the monomers to produce a first polymeric product having at least one functional group. This first polymeric product is then continuously directly charged into a second reaction zone together with at least one modifier reactant having a functional group that is complementary to the functional group of the first polymeric product. At least a portion of the modifier reactant reacts with at least one of the functional groups of the first polymeric product to produce a second polymeric product which incorporates at least a portion of the modifier reactant, such that the second polymeric product is a reactive polymer.

摘要:
A novel information processing system, information processing method, program, and recording medium related to electronic business cards are provided. An information processing system for generating data of an electronic business card, stores personal information, and stores one or more presentation method data. Each of the presentation method data specifies a method for presenting the personal information in the electronic business card. The information processing system generates the data of the electronic business card by using the personal information and one of the presentation method data, when an instruction to use the data of the electronic business card is inputted.

In an optical disk recording and reproducing device which uses an optical disk having at least a first recording layer and a second recording layer, a thickness of a spacer section between the first recording layer and the second recording layer is measured, an amount of defocus with respect to the second recording layer is set based on the measured spacer thickness, and a focus servo operation is performed for focusing the laser light irradiated from an optical pickup device on the second recording layer.
摘要:
A process for producing chlorine comprising the step of oxidizing hydrogen chloride in a gas containing hydrogen chloride with a gas containing oxygen in the presence of a catalyst, wherein the oxidation of hydrogen chloride is carried out in at least two reaction zones each comprising a catalyst-packed layer, which are arranged in series, and a temperature in at least one of said reaction zones is controlled with a heat exchange system. According to this process, the stable activity of the catalyst is maintained and chlorine can be stably obtained at a high yield since the excessive hot spot in the catalyst-packed layer is suppressed and the catalyst-packed layer can be effectively used.
摘要:
A high pass filter 32 having a cut-off frequency of 200 Hz and a cut-off response of +12 dB/OCT and a low pass filter 33 having a cut-off frequency of 400 Hz and a cut-off response steeper than −24 dB/OCT are used to pick out components in a double overtone region of 200˜400 Hz of a bass musical instrument such as a base or a bass drum from an input audio signal. The component which is picked out is input to distortion applying means 34 having an input-output response which is a non-linear response having no point symmetry with respect to 0 point, thus applying a distortion to cause even-numbered overtone components to be produced. An output from the distortion applying means 34 and the input audio signal are summed in a summer 18 to be delivered. Natural tones which have boosted bass tones and which are free from impurity are obtained.
