摘要:
A multilayer-type optical recording medium having a translucent recording/reproducing functional layer containing a first protective layer, a second protective layer, a recording layer, a third protective layer, a reflective layer and a fourth protective layer in this order relative to incident laser light. The second protective layer and the fourth protective layer are made of the same kind of material. The refractive index of the second protective layer is higher by at least 0.3 than the refractive index of the first protective layer. When the film thickness of the second protective layer is set as D2, the film thickness of the fourth protective layer is set as D4, and the reflectivity before recording when the laser light is focused on the recording layer is set as R, the derivatives d(R)/d(D2) and d(R)/d(D4) have opposite signs from each other.

A method transmitting and receiving data other than voice data and preventing deterioration in quality of communication voice data due to transmission and reception of the other than voice data, and utilizing a limited communication bandwidth when a plurality of users conduct the broadcast communication through common use of the conference room on the network. Upon a user terminal transmitting second data, verifying whether any of a plurality of identified user terminals has a right of transmission of first data. The method further includes that upon a user terminal having the a transmission right of first data, setting a value obtained by subtracting the communication bandwidth required for transmission of the first data from the communication bandwidth which each user terminal can use as the communication bandwidth for transmission of the second data. Upon no user terminal having a transmission right of first data, setting a communication bandwidth that each user terminal can use as the communication bandwidth for transmission of the second data.

A presence server stores a presence that is identified by presence IDs “a1” and “a2”, as the presence of a user “A”. User “A” can pass a card that they hold through a card reader at a timing of their choosing. The card reader reads in data from the card and transmits a renewal request to the presence server. The renewal request includes a renewer ID, an object ID, category information and the presence. When the presence server receives the renewal request, it specifies the presence ID “a1” of user “A” to be the presence that is to be renewed, based on the category information, and moreover, rewrites the presence of the presence ID “a1” to a presence “meeting room A” that is included in the renewal request. Thus, the card reader can renew the presence designated by the “category information”. As for the presence that is renewed, it is notified to a watcher of the presence “a1” from the presence server.

The object is to enable suppression of an excessive number of changes in assignment of a server in charge of communication in response to movement of a terminal. A position-information acquisition unit in a computer acquires information on the position of a mobile terminal as a candidate for a destination of information provision. Then, a zone determination unit determines whether or not the mobile terminal is in a coverage zone or a margin zone on the basis of the information on the position. An information provision unit starts the information provision to the mobile terminal when the mobile terminal enters the coverage zone, and ends the information provision to the mobile terminal when the mobile terminal goes out of the margin zone.

摘要:
To obtain an optical information recording medium in a favorable initially crystallized state, by carrying out initial crystallization at a high linear velocity (specifically at least about 25 m/s), i.e. at a linear velocity higher than the erasable linear velocity for the optical information recording medium. A process for producing an optical information recording medium having a phase-change type recording layer on a disk-shape substrate, which comprises a step of obtaining a recording medium having the recording layer formed thereon, and an initial crystallization step of initially crystallizing the recording layer by scanning the recording medium in the circumferential direction with a beam spot formed by irradiating the recording layer with a focused beam, wherein in the initial crystallization step, the linear velocity when the recording medium is scanned in the circumferential direction with the beam spot, is increased toward the outer circumferential portion of the recording medium, and the intensity of the focused beam is increased as the scanning linear velocity is increased, so that the entire initial crystallization area is initially crystallized.
摘要:
A data output apparatus checks data accumulated state in the accumulating unit at a preset check interval, and changes at least one setting among an initial accumulation amount to be used as a basis for starting to output the data accumulated in the accumulating unit, an upper accumulation limit amount to be used as a basis for discarding accumulated data, and a check interval, according to a discarded state of the data based on check results. Therefore, in the data output apparatus such as an IP telephony terminal apparatus, it is possible to prevent sound interruption and limit a lowering of communication quality.
