A base station includes: a data classification function for classifying data to be transmitted to terminals into audio data and terminal-basis ordinary data and generating downstream communication traffic information; a queuing function for generating an ordinary data transmission queue and an audio data transmission queue from the classified data; a communication quality control parameter setting function for setting communication quality control parameters for the respective queues; a transmission and reception portion for transmitting data in the queues according to the communication quality control parameters at a time of transmission; a reception data detection function for acquiring upstream communication traffic information from reception data received from each of the terminals; and a communication quality control parameter control function for dynamically adjusting each of the communication quality control parameters in the communication quality control parameter setting function, based on the downstream and upstream communication traffic information.

In order to enable formation of a smooth and dense oxide superconducting film with no clear appearance of grain boundaries in a fine structure even at a high film forming rate, a laser ablation method is employed to apply a laser beam 2 to a target 1 containing components of an oxide superconductive material and deposit particles, which are thus scattered from the target 1, on a substrate 3, while gaseous oxygen is supplied from a gaseous oxygen inlet 7 toward laser plasma 6, which is generated by the application of the laser beam 2.

An object is to provide a method and an apparatus for improving a residual stress in a tubular body, which are enabled to improve the residual stress reliably by clearly defining controlling rage for treatment conditions without depending on an installation state and configuration of the tubular body. When a cylindrical tubular body (2) is improved in its residual stress by locally irradiating an outer-circumferential surface of a welded portion (C) of the tubular body (2) with laser beams (5a) and by moving an irradiation area (s) in an circumferential direction, a plurality thermocouples (9) are installed on the tubular body (2) to be improved, a temperature history of the outer surface of the tubular body (2) by the irradiation of the laser beam (5a) is managed by measuring the temperature history itself.

摘要:
Power generation with a gas turbine using a gasified fuel of inferior quality is accomplished with high efficiency by a method which comprises bleeding part of highly compressed air emanating from an air compressor driven by a gas turbine and introducing the part of highly compressed air into an oxygen adsorbing tower containing an oxygen adsorbent thereby causing the oxygen from the highly compressed air to be adsorbed by the oxygen adsorbent and, at the same time, allowing the nitrogen gas from the highly compressed air to flow in a highly compressed state through the oxygen adsorbing tower, desorbing the adsorbed oxygen from the oxygen adsorbent under a vacuum, compressing the oxygen gas resulting from the desorption and gasifying a fuel of inferior quality with the compressed oxygen gas as an oxidizing agent, effecting combustion of the gasified fuel of inferior quality with the remainder of the compressed air produced by air compressor, mixing the gas arising from the combustion with the highly compressed nitrogen gas having flowed through the adsorbing tower, and introducing the resultant mixture into the gas turbine thereby driving the gas turbine and inducing power generation.
摘要:
A training simulator for selectively executing one of training items of simulation bases to be executed by the operation on a trainer console requesting the responsive operation on a trainee console of storing a current time and information of current training status in response to reception of a first command from the trainer console, and of reviewing the executed training item in accordance with the stored current time and information in response to reception of a second command from the trainer console.
摘要:
There is provided an optical transmission system that can identify any transmitting stations generating optical beats found within the transmission band being used for optical signals so that any degradation in the quality of the signals being transmitted and adversely affected by the optical beats may be eliminated. The light sources of the transmitting stations giving rise to the optical beats generated in the detector as a result of the differences of the wavelengths of the optical signals coming from the light sources of the transmitting stations and adversely affecting the transmission band being used for the electric signals originating the modulated optical signals are identified by changing the state of polarization of light of the optical signals coming from the light sources of the plurality of transmitting stations. In other words, the light sources of the transmitting stations that are giving rise to the optical beats adversely affecting the transmission band being used for the electric signals originating the modulated optical signals can be identified by changing the state of polarization of light of the optical signals coming from the light sources of the transmitting stations on a one-by-one basis and observing the produced optical beat at the receiving station.
