Abstract: The present invention has a hierarchical DLL circuit comprising a rough DLL circuit for phase adjustment by rough delay unit and a fine DLL circuit for phase adjustment by smaller, fine delay unit. When phase adjustment begins, only the rough DLL circuit operates; when the rough DLL circuit locks on, phase adjustment by the rough DLL circuit ends and the delay amount of the rough DLL circuit is set. When the rough DLL circuit locks on, the fine DLL circuit is caused to operate. In this way, the phase of the timing clock generated by the DLL circuit is adjusted only by fine delay units even if the phase of the reference clock is temporarily shifted by a large amount due to power source noise or the like. Consequently, in the event of temporary phase shifting, the amount of jitter in the timing clock can be suppressed to the small amount of a fine delay unit.

Abstract: An overhead power transmission line formed by stranding at least one outwardly projecting strand at the outermost layer of an overhead power transmission line formed by a plurality of strands. At least the outwardly projecting portion of the outwardly projecting strand is composed of an organic material. The outwardly projecting strand has a projection height H within a range defined as 1.5 mm≦H≦7.0 mm. By setting the projection height H of the outwardly projecting strand equal to or larger than 1.5 mm, the wind noise characteristic can be conspicuously improved. Further, by setting H≦7.0 mm, the outwardly projecting strand comprised by an organic material is made easily crushable, so the gripping portions of spacers, dampers, and other parts which have been conventionally used can be used as they are.

Abstract: Circuits for the restoration of a drooped signal are disclosed. In the asynchronous mode circuit, the drooped signal can be restored by detecting the peak of the positive amplitude and the peak of the negative amplitude and take the difference between the two peaks. This difference signal is fed back the equalizer. In the synchronous mode circuit, the drooped signal is sliced and passed to a regeneration circuit. The regeneration circuit uses reference voltage signals and phase information from the slicer to generate a regenerated signal. The regenerated signal is compared with the equalized signal to generate a difference signal, again fed back to the equalizer. The sliced signal is also fed to a clock recovery circuit which recovers the clock signal embedded in the received signal. The two circuits can be combined to provide an optimal circuit for the restoration of a drooped signal.

Abstract: In a legged mobile robot, in particular in a biped robot, the feet position and/or posture is determined in such a manner that compensating moment of total floor reaction force about a desired total floor reaction force central point is determined, based upon the detected posture inclination of the robot, and is distributed to each of the feet such that each foot rotates respectively by predetermined angles about the desired total foot floor reaction force central point and a desired foot floor reaction force central point, in order to control the actual total floor reaction force and the actual foot floor reaction force acting on the robot properly such that it walks on a floor having not only a slope extending over a relatively long distance, but also existing locally. With this, it becomes possible to control the floor reaction force acting on the robot easily and properly, without causing any interference to occur.

Abstract: A wall is provided on one side of a web of paper or the like traveling along a predefined path, and an airstream is produced between the wall and the traveling web approximately in the direction of web travel. A transverse static pressure gradient is established across the airstream, causing the stream to flow close to the wall surface. This phenomenon is called as the Coanda effect. A partial vacuum created in the airstream causes the web to deflect from its normal path and to be drawn to the wall surface under sufficient pressure to be kept from fluttering. This method of web flutter control is applied to the splicing of webs, as from one roll to another in a web-fed rotary printing press. The web being unwound from the old roll has been susceptible to fluttering while being spliced to the new roll, such web fluttering being eliminable by providing a wall member along the web path and producing an airstream between the web and the wall member.

A monitoring radiography is performed with a small dose before a production radiography. A radiographic condition for the production radiography, specifically a radiation emitting period or a tube current of a radiation generator, is computed based on a ratio between a quantity of charges in a region of interest collected from the two-dimensional radiation sensor in time of the monitoring radiography and a desired quantity of charges in the region of interest in time of the production radiography. The production radiography is carried out based on a result of the computation to acquire a high quality image.
