Abstract: An apparatus for recording information includes a writing device that can be manually manipulated to record information on at least one sheet. An electronic device receives the information recorded on the at least one sheet. The apparatus therefore substantially simultaneously records information on at least two mediums.

Abstract: An information recording and reproducing apparatus provides users with an easy designation of a playback start position and a playback time. Sound data is sequentially stored in association with time data and information such as a letter and a symbol is inputted with a marker with which a user writes. When the user designates the letter or symbol with the marker, playback of the sound data recorded at an input start time of the letter or symbol is started. When the playback end is indicated using the marker, the playback of the sound data is terminated.

Abstract: When a point on a tablet is designated by a marker, a recording indication signal is on, and recording of sound data is started. When the marker is released from the tablet, the recording indication signal is off, the recording of the sound data is finished, and coordinate data of the point and the sound data are linked. When information, such as characters, is inputted on the tablet using the marker, coordinate data based on the input and the sound data are linked through the coordinate data of the point. When the information such as characters is designated using a marker for playback, the sound data is played back.

Abstract: A communication system having a client device, a processing server and a contents server. When the client device makes a request for textual information to the processing server, the processing server searches for and receives the requested textual information from the contents server. Then, the processing server generates both abridged textual information and voice information from the received textual information, and transmits the abridged textual information to the client device. The client device requests the voice information, which corresponds to an unabridged version of the textual information, at the user's request.

Abstract: A stroke data editing device, for editing stroke data, indicating at least one stroke of a coordinate input device, comprising, a stroke data storage unit that stores stroke data, each piece of the stroke data corresponding to one stroke of a coordinate input device, a stroke data retrieving unit that retrieves, according to a predetermined condition, at least one piece of the stroke data from the stroke data storage unit so that the retrieved stroke data corresponds to at least one stroke included in a predetermined area, and a stroke data editing unit that edits at least one piece of the stroke data retrieved by the stroke retrieving unit on a stroke basis.

Abstract: A stroke data input unit, of each of input display boards, transmits to a display unit coordinate data for characters or graphics obtained by an input board unit, by attaching identification (ID) information of the input board unit to the coordinate data. A synchronization display controller of the display unit displays the characters or graphics based on the coordinate data received through a receiver, and the ID information of the input display boards, in respective areas of a display panel. When a user makes a stepping display request, the synchronization display controller reads out the data stored in the stroke data storage unit to estimate an input time for strokes of the characters/graphics. The characters/graphics estimated to be input at approximately the same time in the input display boards, may be displayed in the respective areas of the display panel at approximately the same time.

Abstract: An apparatus for driving an electric motor, including a full-wave rectifier which rectifies an alternating current supplied from an alternating-current power supply, and supplies a full-wave rectified current to the motor, a chopper which chops the full-wave rectified current supplied from the rectifier to the motor so that the chopped current is applied to the motor, and a control device which generates a chopping pulse signal having a first signal characteristic corresponding to a given motor control target and a second signal characteristic to reduce an alternating-current component of the full-wave rectified current supplied to the motor, the control device supplying the chopping pulse signal to the chopper so that the chopper chops the full-wave rectified current according to the chopping pulse signal.

Abstract: An apparatus for driving an electric motor according to a given control target, including a control circuit which generates a control command signal corresponding to the control target, a chopping signal generator which generates a chopping signal based on the control command signal generated by the control circuit, a full-wave rectifier which rectifies an alternating current supplied from an alternating-current power supply, and supplies a full-wave rectified current to the motor, and a chopper which is connected in series to a series circuit including the motor and the full-wave rectifier and which chops the full-wave rectified current supplied to the motor according to the chopping signal generated by the chopping signal generator.
