摘要:
It is an object of the present invention to suppress an abrupt gain change and smoothly and highly accurately control transmitted electric power even if the transmitted electric power greatly changes when a closed loop control that crosses the threshold value as the detection limit of the transmitted electric power. The transmitted electric power of a self-station is detected to obtain an error between the detected transmitted electric power of the self-station and transmitted electric power set in accordance with a transmitted electric power control bit sent to the self-station from the other station. A buffer unit such as a transmitted electric power deciding part, an error integrating part or the like is provided for preventing the obtained error from greatly changing upon great change of the transmitted electric power when the transmitted electric power is controlled by crossing the threshold value as the detection limit of the transmitted electric power. Thus, an error when the gain of the variable gain amplifier is suppressed.

Disclosed is an automotive floor panel assembly, in which the floor panel assembly is stamp formed into a prescribed shape from at least one piece of sheet metal blank which consists of a first panel section made of sheet metal stock of a first thickness, and a second panel section made of sheet metal stock of a second thickness which are butt welded to each other along opposing edges thereof by using a high energy beam. Because the butt welding is carried out on flat panels, welding quality can be maintained at a high level without any substantial difficulty, and the resulting blank can have a highly uniform finish even though it includes a plurality of parts having different thicknesses. By suitably arranging the various parts having different thicknesses to different parts of the floor panel assembly in an optimum fashion, it is possible to achieve a maximum mechanical strength and a maximum rigidity with a minimum amount of material or involving a minimum weight. Also, the floor panel assembly can be applied either to a front floor panel assembly or to a rear floor panel assembly.

An image forming apparatus connected to a conveying-speed-changeable sheet post processing device includes a discharging unit which discharges a sheet in a reverse discharge mode with front and back surfaces of the image-formed sheet reversed, and a non-reverse discharge mode without front and back surfaces of the image-formed sheet reversed, and discharges the sheet at a first speed or a second speed lower than the first speed; and a control unit which controls the discharging unit to discharge the sheet at the first speed in the reverse discharge mode and at the second speed in the non-reverse discharge mode. When the sheet is discharged at the second speed, the control unit controls the discharging unit to discharge a subsequent sheet at the second speed even if the subsequent sheet is to be discharged in the reverse discharge mode.
