An ARP server which can inform a calling terminal of an address suitable for an intended communication with a receiving terminal among a plurality of addresses usable for that purpose. The ARP server is equipped with an ATMARP table consisting of a plurality of unit tables each of which correlates an IP address and a plurality of ATM addresses. When receiving an inquiry about an ATM address corresponding to a certain IP address, the ARP server checks free bandwidths of circuits relating to respective ATM addresses in a unit table that corresponds to the IP address of interest, and informs the terminal that issued the inquiry of an ATM address with the largest free bandwidth.

A hemoglobin-encapsulated liposome is provided. The hemoglobin-encapsulated liposome comprises a liposome and an enzymatically active hemoglobin solution encapsulated therein. The hemoglobin solution is supplemented with glucose; and at least one member selected from the group consisting of adenine, inosine, and adenosine triphosphate; and optionally, further with phosphoenol pyruvate. The thus supplemented hemoglobin solution encapsulated in the liposome exhibits an improved resistance to conversion to methemoglobin as well as an adequately regulated affinity for oxygen. Therefore, the hemoglobin-encapsulated liposome of the present invention is useful as a blood substitute.

A method for manufacturing a printed circuit board is to form on a top surface of an insulating substrate a layer of such plating ground as a metal film, to irradiate such electromagetic wave as a laser to a boundary edge zone of non-circuit parts with respect to circuit-printing parts on the insulating substrate in correspondence to a pattern of the non-circuit parts to remove the plating ground layer at the part irradiate by the electromagnetic wave with the plating ground layer at the non-irradiated part left as formed, and thereafter to form a plating on the surface of the plating ground layer at the non-irradiated parts, whereby it is enabled to allow the laser irradiation to be carried out only with respect to the boundary edge zone of the non-circuit parts, without irradiating all over the non-circuit parts.

A lead-acid battery having a reliable exhaust structure suppressing unexpected leakage of acid mist and gas to outside the battery. The battery having a first gas exhaust path A for guiding gas generated in a plate pack from a cell compartment to a recess formed in a cover. A top lid is placed on the top surface of the cover to extend over the recess. The top lid and the cover form a closed shape so that the recess and the top lid form an exhaust chamber. A through hole for establishing communication between a first opening formed in the recess and a second opening formed in the outer surface of the cover, serves as a second gas exhaust path B which establishes communication with the first gas exhaust path A through the exhaust chamber.
摘要:
A base station outputs annunciation information which corresponds to a plurality of radio cells established by a 3G public base station and an LTE public base station and which is different from annunciation information output from the 3G public base station and the LTE public base station into a target region X and forms a radio cell. A mobile station that enters the radio cell receives the annunciation information of the radio cell and executes a position registration process. An information administration device can thereby find the mobile station based on the position registration process even in the environment where a plurality of radio cells to which different frequencies are assigned are established geographically overlapping with one another.

摘要:
A radio access device includes a controller signal processing unit (RNSAP unit) that processes a signal exchanged with a radio network controller (RNC); and a switching center signal processing unit (RANAP unit) that processes a signal exchanged with a switching center. The RNSAP unit requests to establish a communication path between the radio access device and the RNC and a communication path between the RNC and a BTS by transmitting a request signal to the RNC. Subsequent to receiving an acknowledgement signal corresponding to the request signal from the RNC, the RANAP unit requests to establish a communication path between the switching center and the RNC. Subsequent to receiving, by the RANAP unit, an acknowledgement signal corresponding to the request signal from the switching center, a communication path between the radio access device and the UE is released.
