Abstract: PROBLEM TO BE SOLVED: To obtain a high-resolution incremental encoder. SOLUTION: The encoder 1 is provided with four detectors, and each detector creates a square-wave pulse signal which forms one period T every time a rotating shaft is rotated by a predetermined angle θ and outputs it from each of A-phase to D-phase output terminals 11-14. A-phase and B-phase pulse signals and C-phase and D-phase pulse signals each have a T/4 phase difference, and A-phase and C-phase pulse signals and B-phase and D-phase pulse signals each have a T/8 phase difference. The A-phase and B-phase pulse signals and the C-phase and D-phase pulse signals are inputted to the input terminals 21 and 22 of an updown counter 2 via EXCLUSIVE OR circuits 3 and 4, respectively. The counter 2 executes up count or down count every time the counter 2 captures each edge of each pulse signal. Therefore, the angle of rotation of the rotating shaft is detected at a resolution of θ/8 corresponding to a phase difference of T/8.

Filed: 2000-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a method and a system for film deposition by which a transparent conductive film having excellent characteristics can be deposited without damaging an undercoat layer on a wafer. SOLUTION: A material table 53 fed into a hearth 51 is heated by the electric current from a plasma beam PB and the top of the material table 53 is sublimated to stably emit film material vapor. The vapor is ionized by the plasma beam PB and allowed to adhere, e.g. to the surface of the wafer W to which negative voltage is applied and forms a film. In the case that the tablet 53 has an oxygen deficient composition, plasma damage to the undercoat layer of the wafer W such as color filter can be reduced comparatively. Moreover, the resultant ITO film deposited on the wafer W becomes a low stress film and hardly causes defects such as cracking and wrinkling.
