摘要:
A communication quality evaluation system, a device, a method, and a program for evaluating communication quality at an arbitrary location, in the form which can actually felt by a user, are provided. According to an instruction from an evaluator, a control device displays a map or layout diagram of a specified area on a map/layout diagram display device and specifies an evaluation point within a display range of the map or the layout diagram. According to the network quality estimated by a network quality estimation unit, a network quality simulation unit for estimating the network quality when communications are performed at the evaluation point deteriorates the evaluation data and transmits the data to an evaluation device. The evaluation data deteriorated is a sample of data actually transmitted and received in the communication system. The evaluation device uses a communication device actually used by a user in the communication system.

A radio wave arrival status estimating system characterized by having an estimating means that estimates whether the physical characteristic of a radio wave received at the reception point of a radio system to be evaluated has reached the minimum allowable level for determining the characteristic of the radio system; that estimates an arrival status of the radio wave at the reception point by applying a first radio wave propagation status estimating technique to the reception point when estimating that the physical characteristic has reached the minimum allowable level; and that estimates an arrival status of the radio wave at the reception point by applying a second radio wave propagation status estimating technique to the reception point when estimating that the physical characteristic has not reached the minimum allowable level.

A radio wave characteristic estimation system and its method estimate radio wave propagation characteristics in an investigation object area in a part of a coverage area of a wireless system, which becomes an object of the estimation, at high speed and with high precision, when the coverage area is wide. In a three-dimensional area including a plurality of contents, a transmission source and the investigation object area to be investigated as to the propagation environment of radio waves emitted from the transmission source are provided. When estimating a radio wave propagation environment in the investigation object area, a general radio wave propagation situation acquisition unit finds general radio wave propagation situation within the investigation object area or in the vicinity thereof. A pseudo transmission source preparation unit prepares finite pseudo transmission sources to simulate the general radio wave propagation situation. A radio wave propagation estimation unit conducts detailed radio wave propagation estimation by designating the finite pseudo transmission sources as new transmission sources and an analysis area including the investigation object area as an analysis object.
摘要:
The present invention is intended to provide a position-dependent information representation system which can allow persons other than evaluators to readily recognize at which positions the respective evaluators are evaluating information. Control device causes map/layout display means to display a map or a layout chart of a specified area in according to an instruction of the evaluator, and specifies an evaluation point specified by the evaluator in the display range of the map or the layout chart displayed according to an instruction of the evaluator. Information acquiring means acquires information data representing information of the evaluation point. Information representation section represents the information data. ID receiving means and information representation section connected to control device are connected through communication medium, such that the correspondence of the evaluation point to information representation section can be visually recognized, and information acquiring means transmits the acquired information data to information representation section.

摘要:
In an aperture stop mechanism, two aperture blades are arranged so as to overlap each other and form a single light passage opening into which light utilized in imaging is introduced with the respective edge portions of the two aperture blades. A drive mechanism drives the two aperture blades in directions different from each other, whereby the aperture area of the light passage opening is changed within a predetermined range. When the two aperture blades are located at a minimum aperture position where the aperture area of the light passage opening is minimum within the predetermined range, the two aperture blades are provided so that the single light passage opening surrounded by boundaries including eight straight lines is constituted of the respective edge portions of the two aperture blades.

In an insertion hole formed in an adapter, a side wall which presses an insertion piece of a stopper with an urging force of a spiral spring has a wall surface parallel to a virtual straight line passing a center of the adapter and positioned on the virtual straight line. Thus, a direction which the wall surface of the side wall presses the insertion piece of the stopper is along a facing direction which the side wall and another side wall face each other, and is not inclined outward in a radial direction of the adapter with respect to the facing direction. Thereby, a pressing force applied from the wall surface of the side wall to the insertion piece of the stopper does not cause the insertion piece to be extruded from the insertion hole. Thus, insertion state of the insertion piece to the insertion hole can be satisfactorily maintained.

A fuel cell module includes in a casing: a fuel cell stack that is formed by stacking a plurality of unit cell; an oxidant gas distributing member that is disposed at a side surface, that extends in a stack direction of the unit cells, of the fuel cell stack that extends in a direction from one end to another end of each of the unit cells, and that supplies the oxidant gas to the another end of each unit cell after supplying the oxidant gas through the oxidant gas distributing member from the one end to the another end; a reformer disposed at the one end; and a combustion portion that is disposed between the one end and the reformer. The oxidant gas distributing member has a higher thermal conductivity at the one end side of the unit cells than at the another end side of the unit cells.
