IPC: B62D5/04
Filed: 2002-11-19
Abstract: <P>PROBLEM TO BE SOLVED: To diminish a rapid change in a steering angle caused by an error correction in the middle of control, and to prevent a vehicle behavior from being astable.  <P>SOLUTION: A steering actuator is controlled so that a rudder angle changes according to the steering angle from the middle point position of a steering member. The existing position of the steering member is found, from a reference position which is obtained by correcting with a reference error generated in last control, a steering start position which is found from the output of a sensor for detecting the absolute position of the steering member and is the absolute position of the steering member at a control start, a signal corresponding to a steering angle change of the steering member which a position sensor outputs, and the steering direction of the steering member. The position sensor outputs a position specifying signal, when the steering member is located at a fixed predetermined position. The existing position is corrected by an error which is a deviation between the existing position of the steering member and the generated position of the position specifying signal and is generated in a control performed this time. By adding the error to a value which corresponds to the accumulated value of errors generated in controls performed last time and before that, a reference error in the next control is found.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for treating waste water after detoxification of gaseous PFC (perfluorocompounds) used for production of semiconductors, liquid crystals, and electronic components, a method for recycling fluorine compounds in the waste water in particular, and an apparatus therefor.  <P>SOLUTION: The subject method for treating the fluorine-containing waste water has an electrodialysis process in which the fluorine-containing waste water is desalted and condensed. Electrodialysis is performed to an extent that desalted liquid is regenerated as replenishment water to the source of generating the fluorine-containing waste water and hydrofluoric acid concentrate is regenerated as a hydrofluoric acid solution of utilizable concentration. According to this method, the fluorine-containing waste water is treated by using the electrodialysis process while leaving hydrofluoric acid acidity as it is, and thereby concentrated water with targeted hydrofluoric acid concentration and desalted water can be obtained. Since calcium ions, or the like, which may cause trouble as a scale component, is fully removed, the desalted water can be reutilized as replenishment water of a detoxifying apparatus. On the other hand, the concentrate having 3 to 10 wt% hydrofluoric acid concentration is reutilized as steel pickling liquid, or the like. Further, fluorine is separated by crystallization as a silicofluoride, and thereby the deposite of hexafluorosilicate can be recycled as a resource.  <P>COPYRIGHT: (C)2004,JPO
