摘要:
A data communication apparatus is provided with a VoIP processor and a modem that interchangeably executes a standard communication mode and a high-speed communication mode, the standard communication mode exchanging the voice packet at a predetermined transfer rate, the high-speed communication mode exchanging the voice packet at a rate faster than the rate of the standard communication mode. When capability information of an opposing apparatus is obtained, in accordance with a predetermined communication protocol, and it is detected that the opposing apparatus has the high-speed communication mode, the high-speed communication mode is selected for execution.

A dustproof structure for an electronic equipment includes internal switches disposed in a housing forming an external frame of the electronic equipment and an opening for use in operating the internal switches. The dustproof structure further includes a shutter plate for opening or closing the opening; and a cover plate for supporting the shutter plate, the shutter plate being freely slidable between the cover plate and the housing. A slide recess serving as a sliding area of the shutter plate is formed in the housing or the cover plate.

A data communication apparatus includes a communication section that performs a pre-communication protocol with a destination terminal and transmits data to a destination terminal. A memory stores data and communication parameters corresponding to each destination terminal, the communication parameters being utilized to perform communication with the destination terminal. When destination terminal data is stored in the memory, a controller reads the communication parameters corresponding to the destination terminal from the memory, performs the pre-communication protocol with the destination terminal, using the read communication parameters, and omits at least a communication protocol for line probing. When destination terminal data is not stored in said memory, the controller performs the pre-communication protocol with the destination terminal, using communication parameters acquired from the destination terminal under the pre-communication protocol without omitting the communication protocol for line probing.

An agent presentation apparatus for transmitting and receiving a message and operating based on a knowledge base and a rule base. In particular, where an agent for carrying out a user request uses knowledge of a knowledge description or an action description between agents and executes communication, for example. An agent can request a WWW page locally or remotely over a network to retrieve already existing contents and make a presentation that might include one or more of images, voice, and text along with the WWW page. The apparatus can also respond to user questions about the WWW page using the knowledge description and/or the action description, for example.

A vibration damper little depending on temperature, capable of damping plural resonance vibrations over a wide frequency region as well as damping a specific frequency vibration is provided. The vibration damper comprises a housing formed of a rigid material, having an internal space and fixed to a vibration transmitting member, an elastic body inserted in the internal space not bonded thereto with a gap in a direction of vibration of the housing, and a weight integrally supported by the elastic body so as not to touch the housing. The elastic body and the weight form a dynamic damper.

The rotation of the inner press roller 16 is synchronized with the rotation of the printing drum 10 by the gear train including a gear wheel 22 coaxial with the printing drum, a gear wheel 24 meshing with the gear wheel 22 and rotatably supported by an arm 26 swingable about the central axis of the printing drum, and a gear wheel 28 meshing with the gear wheel 24 and coaxially connected with the inner press roller 16 to rotate therewith and rotatably supported by an arm 18 swingable about a pivot axis Ob parallel with and distant from the central axis Oa of the printing drum. In the gear train, a brake 86 or 90 is provided for braking the gear wheel 28 or 24 to control the biasing out operation of the inner press roller 12 against the circumferential wall 12 of the printing drum. The braking action may be temporarily increased during a starting up of the printing operation. The distance between the axes of the gear wheels 24 and 28 may desirably be restricted not to increase beyond a predetermined distance.

A stationary tape guide, for use with a magnetic tape recorder having an inclined cylinder mounted on a chassis, the tape-guide containing a guide block mounted on the chassis the guide block having the following features. A first tape surface guide inclined with respect to a first reference plane. A second tape surface guide inclined with respect to the first reference plane and located further from the inclined cylinder than the first tape surface guide. A third tape surface guide oriented orthogonal to the first reference plane and located further from are inclined cylinder than the second tape surface guide. A first tape edge guide extending from the guide block beyond a second reference plane defined by the first and second tape surface guides and having a first tape edge contact surface. A second tape edge guide extending from the guide block beyond a third reference plane defined by the first tape surface guide in cooperation with the cylinder, and having a second tape edge contact surface which is located further from the first reference plane than the first tape-edge contact surface.
