摘要:
[Object] To prevent or reduce the degradation in transmission characteristics caused by fast fading (fluorescent lamp interference) to achieve optimized throughput.[Solution] A process for detecting fast fading (fluorescent lamp interference) is performed (ST2). Fast fading is detected by, for example, detecting a variable light source whose frequency is twice the frequency of an alternating current power supply. When fast fading is detected, a frame length update process is performed (ST3, ST4). In the case of “subject transmission” in which the subject apparatus is the transmitter of a data frame, the setting of the maximum number of aggregations in frame aggregation (A-MPDU, A-MSDU) is changed to “the recommended maximum number of aggregations”. “The recommended maximum number of aggregations” is set in advance so that the UDP throughput can be maximized under the conditions where fast fading has occurred. In the case of “subject reception” in which the subject apparatus is the receiver of a data frame, the subject apparatus sends a request message for limiting the maximum transmission length to the communication counterpart apparatus.

It is intended to develop a technique of pressing and fixing a plate by a uniform force to suppress the occurrence of a crack around a nozzle hole of the plate during use, and provide a sliding nozzle device capable of improving durability of the plate, and a plate for use in the sliding nozzle device. The sliding nozzle device comprises a plate (2) and a plate-receiving metal frame (1) for fixedly holding the plate (2). The plate-receiving metal frame (1) is equipped with: at least two holding members (3) each having two pressing surfaces (31, 32) consisting of a longitudinally-pressing surface and a laterally-pressing surface which are protrudingly provided thereon in spaced-apart relation to each other and each adapted to be brought into contact with a corresponding one of a plurality of side surfaces of the plate (2), wherein the holding members (3) are symmetrically arranged with respect to a longitudinal axis of the plate-receiving metal frame (1); a movable block (6) rotatably supporting the holding members (3); and pressing means adapted to press the movable block (6) toward the plate. An angle between the longitudinally-pressing surface (31) and the longitudinal axis of the plate-receiving metal frame (1) is set in the range of 60 to 90 degrees, and an angle between the laterally-pressing surface (32) and the longitudinal axis of the plate-receiving metal frame (1) is set in the range of 1 to 30 degrees.
