In addition to this way, the molecular beam of the group V element is used with its intensity 15 to 20 times larger than that of the a group III element, or the process temperature is kept about 560 deg.C so that an InAlAs single-crystal containing highly dense Si can be obtained. Consequently, a monocrystal layer with desired electric characteristics and well-distributed density in conduction electrons is easily provided.

IPC: G03B9/24
Filed: 1987-01-29
Abstract: PURPOSE:To obtain stable traveling characteristics by allowing an actuator itself to act as a large load to an aperture member when the driving speed of the actuator exceeds a range determined by upper and lower limit values and setting up the upper and lower limit values correspondingly to the driving direction of the actuator. CONSTITUTION:In respective cases of shutter opening operation, F-value maintaining operation and shutter closing operation, a speed comparator 22 acts as a speed limiter following to a position servo, and when the speed of a servo motor 12 exceeds the range determined by the upper and lower limit values, allows the servo motor 12 itself to act as a load. Since the upper and lower limit values are set up correspondingly to the driving direction of the shutter, the driving speed of the actuator is set up within a proper range corresponding to the driving direction of a shutter blade 13. Consequently, stable traveling characteristics can be obtained.
