Abstract: PROBLEM TO BE SOLVED: To provide radio equipment capable of reducing a delay of a radio network that is autonomously established. SOLUTION: Respective radio equipment 31 to 43 transmit and receive packets PKT having a header HD with a route label stored therein. The route label is composed of either label information A showing that a packet PKT is transmitted along a radio communication path between a transmission source and a transmission destination or label information B showing that the packet PKT is transmitted to an unspecified number of radio equipment within a radio network system 100. The respective radio equipment 31 to 43 determine processing contents of a packet PKT with reference to a route label stored in a header HD of the packet PKT transmitted from different radio equipment and process the packet PKT in accordance with the determined processing contents. The respective radio equipment 31 to 43 process the packet PKT by a data link layer and a physical layer. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide radio equipment capable of reducing delay of a radio network that is autonomously established. SOLUTION: Respective radio equipment 31 to 43 hold a plurality of channels, and select a specified channel whose signal interference amount is relatively low among the plurality of channels when transmitting data. The respective radio equipment 31 to 43 apply spread spectrum to transmission data by a predetermined spread code that is optionally selected among a plurality of spread codes, modulate a spread signal subjected to the spread spectrum by the frequency of a specified channel and transmit the spread signal.

Abstract: PROBLEM TO BE SOLVED: To provide a geometric figure data processing apparatus capable of realizing a stable processing system with a wide application range. SOLUTION: A geometric error processor 3 processes the geometric figure data of an error inclusive form stored in a geometric error data storage 2, by means of an arithmetic operation with error. A data conversion processor 62 converts the geometric figure data of the error inclusive form on which the arithmetic operation with error has been performed to a geometric figure data of no error inclusive form. A geometric processor 7 for obtaining no contradiction detects and eliminates geometric contradiction produced on the converted geometric figure data of no error inclusive form.

Abstract: PROBLEM TO BE SOLVED: To provide a radio device forming a radio network which is autonomously established and performs stable radio communication. SOLUTION: The radio device 1 holds a routing table 20 indicating the absolute positions of radio devices 2-15 with respect to the radio device 1. The routing table 20 consists of the absolute positions of the radio devices 2-15 with respect to the radio device 1 represented by x, y coordinates, and link metric values m1-m32 indicating the degree of stability of communication between the radio devices. The radio device 1, a transmission source, excludes a path having a specific communication distance with which a communication distance between neighboring radio devices causes interruption of radio communication; and decides a path to the radio device 15 being a transmission destination on the basis of a path having a communication distance other than the specific communication distance, with which the communication distance between the neighboring radio devices causes interruption of radio communication. Then, the radio device 1 performs radio communication with the radio device 15 according to the decided path. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To efficiently collect large-scale data by collecting words and phrases in the state of being divided in cells, and adding synonyms and the like to the cells. SOLUTION: When an original sentence inscribed in English is presented (S1), a sentence translated in Japanese (a Japanese sentence) is inputted (S3). When a first prescribed number (at least two, for instance) of sentences are inputted (S5), the sentences are divided for every character string such as words or phrases. At this time, the same character strings are put together in the same cell, and the different character strings are inputted (distributed) in different cells (S7). Partial information such as synonyms and related words of the character string is added to every cell (S11). The words or phrases, i.e., language data, are thus collected being divided in the cells.

Abstract: PROBLEM TO BE SOLVED: To provide a control server for automatically limiting service which each user can access. SOLUTION: A network system 100 has a user terminal 10, a Kerberos authentication server 20, an access control server 30, an application server 40, and a common terminal 50. The user terminal 10 requests a table for service which a user can access to the access control server 30 after the validity of the user is certified by the Kerberos authentication server 20. The access control server 30 computes the reliability of the user after receiving the request for the table, and it makes a service table including the service depending on the computed reliability and transmits it to the user terminal 10. The user terminal 10 utilizes the service held by the application server 40 in accordance with the service table. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To converge the control value of an esper antenna in a shorter time in comparison with a conventional case when directing a main beam toward a desired wave and directing a null toward an interference wave in a control method for the esper antenna. SOLUTION: An adaptive control type controller 20 perturbs the reactance values of respective variable reactance elements 12-1 to 12-6 successively just for a prescribed step width, calculates an evaluation function value for each reactance value, sets the reactance value to a perturbed value when improving the evaluation function value calculated before and after perturbation relatively to each variable reactance value but sets the reactance value to a value before the perturbation when not improving the evaluation function value calculated before and after the perturbation on the other hand, and repeatedly carries out processing for decreasing the step width of next repeating processing to the reactance value of the variable reactance element not improving the evaluation function value into 1/q step width change division coefficient and for inverting the code of the relevant step width.
