Publication number: 20100013467Abstract: A rotation sensor includes a detecting portion, a rotational state determining portion and a pulse generating portion. The detecting portion detects a rotation of a rotational member and outputs a detection signal. The rotational state determining portion determines a rotational state of the rotational member on the basis of the detection signal in a predetermined period. The pulse generating portion generates and outputs a first pulse and a second pulse, of which waveforms differ from each other, in response to a rotational direction of the rotational member after the predetermined period. The pulse generating portion further generates and outputs a third pulse regardless of the rotational state of the rotational member in the predetermined period.Type: ApplicationFiled: July 17, 2009Publication date: January 21, 2010Applicants: AISIN SEIKI KABUSHIKI KAISHA, ALLEGRO MICROSYSTEMS, INC.Inventors: Takashi HARA, Hidenobu MURAMATSU, Glenn A.

Publication number: 20070119476Abstract: A substrate held by a spin chuck is supplied with a chemical solution by a chemical solution nozzle and a processing of the substrate is performed. At this time, the chemical solution supplied to the substrate scatters around and adheres to members (processing cup and splash guard) residing near the substrate.
