Abstract: Providing a connection mode setting apparatus, a connection mode setting method, a connection mode control apparatus, a connection mode control method, and the like realizing shorter time of fining an optimum connection destination at the time of connection for participation/withdrawal to/from the system since network topology itself constructing the system clearly shows that the bandwidths of paths attached to nodes constructing the system are wide at the higher hierarchical level and narrow at a lower hierarchical level, and capable of improving communication performance over a wide range of the system without exerting an adverse influence on the whole system even in the case where resume operation or the like accompanying reproduction of contents data after connection is performed.

Abstract: It is the object of the present invention to provide a processing apparatus, processing method, processing program and recording medium capable of reducing the concentration of load upstream in the communication path of a network, and to improve the efficiency of a network system.

Abstract: A connection state control device is provided that can promptly perform a reproducing operation by smoothly switching channels at each node and reduce the load on the management server in a case where operations are performed so as to sequentially change distribution information to be received at each node in a network system having a tree structure. A node receives content being distributed over a network, and performs an operation of reproducing the received content. When the node is to receive different content being distributed over a different network, the node is connected to the different network. After that, the node receives and reproduces the different content. The node continues to receive the original content but suspends the operation of reproducing the original content after connected to the different network.

Abstract: An apparatus is disclosed for displaying to a viewer an image stereoscopically representing a three-dimensional object to be displayed. The apparatus includes: an emitter emitting light, having an intensity modulating section capable of intensity modulation for modulating an intensity of the light emitted from the emitter; a wavefront-curvature modulator capable of wavefront-curvature modulation for modulating a curvature of wavefront of the light emitted from the emitter; and a controller controlling the intensity modulation and the wavefront-curvature modulation, based on a luminance signal indicative of luminance of the image, and a depth signal indicative of depth of the image. The depth signal is a signal corresponding to depth data produced in a rendering process for the object to be displayed.

Abstract: The object of the present invention is to provide an ink jet recording paper of so-called plain paper type having no coating of pigment on the recording surface which is excellent in image density and color reproducibility of the recorded image and besides has a water resistance of the printed portion. According to the present invention, there is provided an ink jet recording paper which comprises a neutral base paper comprising a wood pulp as a main starting material on which is coated a coating solution containing a fluorescent brightening agent, a water-soluble binder and a cationic polymer fixing agent and in which the coated paper has an ISO whiteness of not less than 95% and a fluorescence intensity of 7–15% measured by a method specified in JIS P-8148 using a xenon flash lamp as a light source.

Abstract: An ink jet recording sheet to be used for a high speed rotary ink jet printing system employing an auxiliary drying device of a dielectric heating type, said sheet comprising a support and a cationic resin attached to the support.

Abstract: In the karaoke system 1, a center 3 is connected to a plurality of karaoke terminals 5 by a coaxial cable 7. The center 3 divides the karaoke song data stored in the memory device 13 over several channels and transmits all the karaoke song data within a fixed time period in succession to the karaoke terminals 5 via the coaxial cable 7. This operation is performed regardless of whether or not a song is requested from one of the karaoke terminals 5. Whether the karaoke data transmitted in succession is data of a requested song is determined by the control portion 41 of a karaoke terminal 5. If so, karaoke performance processes are performed wherein the karaoke data is reproduced and the orchestral accompaniment and lyric image is outputted.

Abstract: In a karaoke system, a central terminal and a plurality of karaoke terminals are connected by a coaxial cable. A polling modem modulates a polling signal to a predetermined channel signal and transmits it to a karaoke terminal and also receives a response signal (signal for responding as to whether a song has been requested) transmitted from the karaoke terminal in response to the polling signal. When a song is requested, the data transmission control portion retrieves the karaoke song data of the requested song from the memory, modulates it via the data transmission modem into an alternating current signal that differs from the channel of the polling signal, and transmits it to the karaoke terminal.

Abstract: Disclosed is an improved fire alarm system for an information providing system having a plurality of terminal devices for providing information to a plurality of operators, respectively. The fire alarm system is provided with a fire detecting sensors. If a fire is detected, a predetermined signal is transmitted to a controller. The controller controls each of the plurality of terminal devices to indicate an alarm information to the operator when the predetermined signal is received.

Abstract: The clock demodulator 25 continually demodulates the clock signal of the control CPU 7 transmitted from the clock modulator 10 of the center S. The terminal control CPU 23 performs processes such as transmission and reception of data with the demodulated clock signal as a reference clock. The time required to synchronize the clocks of the CPUs 7 and 23 is eliminated. Transmission and reception of data is executed quickly as soon as right of transmission is transferred to a terminal.

Abstract: In a data transmission system, a center and a plurality of terminals are connected by a coaxial cable. The center is controlled by a server to transmit mode sense polling signals in succession every predetermined time (for example every 30 seconds) to all of the karaoke terminals connected to the center. The center determines whether each terminal is in a karaoke mode or not based on the mode response signal transmitted from each terminal in response to the mode sense polling signals. The center then transmits request polling signal only to terminals determined as being in the karaoke mode, confirms whether a request for a song has been made, and transmits karaoke data to those terminals that have a request.

Abstract: An information recording system comprising a read/write device including a read/write head for reading and writing information from and on a rotatable data-storage medium rotated by a first drive motor, and electrically operated elements such as a second drive motor for moving the read/write head relative to the data-storage medium, reading and writing amplifiers, and detectors for sensing operating conditions of the recording system such as the angular position of the data-storage medium. Electric power is supplied to such electrically operated elements from a power source via power disconnect switches connected between the power source and the respective electrically operated elements for selective power supply to the individual elements.

Abstract: A method and an apparatus for writing information on a magnetic disk by a single-gap magnetic head, wherein information is first written on a selected track and then the written information is partially erased along opposite edges of the written band. Alternatively, previously written information is first partially erased along one of opposite edges of the previously written band, then new information is written on the selected track, and the newly written information is partially erased along one of opposite edges of the newly written band remote from the above-indicated erased edge of the previously band information. In another alternative form, the previously written information is partially erased along opposite edges of the written band, and then new information is written on the selected track.
