Abstract: PURPOSE:To attain accurate positioning with less adjusting manhour by permitting return light beams from a disk to generate spots by means of the first and second areas and the intermediate third area of an error detection optical element on a four division photodetector on the intersection of two division lines. CONSTITUTION:A hologram element 25 as the error detection optical element has a first area 26, a second area 27, a third area 28 different in lattice patterns. A division line 29 dividing the areas 26 and 27 includes the optical axis 30 of reflected light beams. The areas 26 and 27 have the third area 28 having the different lattice pattern. The area 28 is the center of a circle, namely, it makes a circle with a reflected light axis 30 as the center. When two light spots by the areas 26 and 27 are in the objective positions of the photodetector 2, namely, when they are in an A point 31 and a B point 32 in a state that the adjustment of the photdetector 2 is terminated, the optical spot by incident light beams for the area 28 operate so that it is on the intersection of two division lines of the photodetector 2.

Title: Fluctuation mode flow rate control device
Inventor: IKEUCHI YASUHIDE
IPC: F16K31/04
Filed: 1990-03-30
Abstract: PURPOSE:To prevent the decrease of a flow rate difference of the magnitude of a fluctuation even when slight displacement is produced in the rotation range of a closing piece by rotating the closing piece approximately in the same angle arc in two rotation directions of the closing piece based on a state where the direction of a fluid pass hole coincides with the direction of a flow passage. CONSTITUTION:An angle detecting circuit 7 detects an angle theta between the direction of a fluid pass hole 4 of a closing piece 3 and the direction of a flow passage 2. When the detecting angle theta attains an angle + or -alpha(approximate + or -45 deg.) set by a maximum rotation angle setter 9, an inversion signal is outputted from the angle detecting circuit 7 to a motor inverter 8, and the rotation direction of the closing piece 3 is inverted through switching of polarity of a motor 5. As a result, the closing piece 3 is rotated with the aid of the motor 5 in a manner to oscillate between theta=-alpha and theta=+ALPHA. For example, even when displacement  alpha is produced in the rotation range of the closing piece 3 due to an initial set error between a potentiometer 6 and a ball valve 10, a difference in the magnitude of a fluctuation may be increased but it is never decreased.
