摘要:
A wireless LAN system that includes a plurality of stations and an access point, interconnected via a network, and supports QoS has infrastructure mode and a Direct Link. In the infrastructure mode, data communication is performed between stations STA via an access point AP. In the Direct Link, data communication is performed directly between the stations STA. The access point AP performs a process for reserving a bandwidth 2W that is twice a bandwidth W required when the Direct Link is used, in response to a QoS bandwidth reservation request when the Direct Link is used from a station STA. As a result, the QoS of data transfer can be ensured even when the Direct Link is terminated.

In a main body of a camera, a recording unit is disposed which is capable of recording specific information of a photographing lens or an accessory. When the specific information of the presently attached photographing lens or accessory has been already registered in the recording unit, the main body of the camera does not acquire all the specific information from the attached photographing lens or accessory by data communication. In a case where the specific information of the attached photographing lens or accessory has been registered in the recording unit, the only identification information of the interchangeable lens or accessory can be enough, even if the data communication is necessary. In consequence, a communication time with respect to the interchangeable lenses or various types of accessories can be reduced as a whole.

In a method of producing a molten aluminum-killed steel for forming a thin steel sheet, molten steel tapped from a converter is decarburized to a predetermined carbon concentration by using a vacuum degasser, and Al is added to the molten steel in the vacuum degasser to deoxidize the molten steel. A material containing metallic Ca is then added to the molten steel to produce a Ca content of about 0.0005 to 0.005 wt %, and to satisfy [%Ca].times.[%S].ltoreq. about 2.times.1 0.sup.-5. Thereafter, degassing is performed on the molten steel.

A fabrication system for fabricating a three-dimensional object includes processing circuitry. The processing circuitry estimates, according to a fabrication condition and fabrication data, a three-dimensional object to be fabricated according to the fabrication data and corrects the fabrication data according to an estimation result of the three-dimensional object estimated by the processing circuitry.

An image processor includes a first converter to convert input images into images in a different coordinate system from that of the input images according to first conversion data based on a projection model, a position detector to detect a connecting position of the images converted by the converter, a corrector to correct the first conversion data on the basis of a result of the detection by the position detector, and a data generator to generate second conversion data for image synthesis from the conversion data corrected by the corrector on the basis of coordinate conversion, the second conversion data defining the conversion of the input images.
摘要:
An image capture system including two imaging systems of the same structure each having a wide-angle lens, which includes a front group, a reflection surface, and a rear group arranged in order from an object side, has a field angle larger than 180 degrees, and bends an optical axis of the front group toward the rear group by the reflection surface, and an imaging sensor, obtains an image in a solid angle of 4π radian by combining images imaged by the imaging systems. Each of the two wide-angle lenses includes the reflection surface between the front group and the rear group, the reflection surfaces are made to be common to the two imaging systems. This reduces an interval between lenses nearest to the object side in the front groups of the two wide-angle lenses, thereby reducing a distance between maximum field angles of the two wide-angle lenses.
