摘要： An absolute encoder wherein tracks are arranged side-by-side on a magnetic drum in the axial direction thereof, and absolute patterns of circulatory random sequence codes are divided and recorded on the tracks, respectively. An additional track for generating sinewaves of two phases in synchronism with the reading of the absolute patterns is provided on the magnetic drum, so that an output can be obained by combining a coarse value of an absolute position obtained from the tracks and a fine value of an absolute position obtained from the additional track. The absolute patterns are detected from the two tracks recorded on the magnetic drum by magnetic resistive elements connected with each other to form circuits each having a three-terminal. Terminals of the magnetic resistive elements are connected through a common line with an electric power source in order to prevent the lines from being crossed.

摘要： A light beam chopping or intercepting apparatus capable of repeatedly and sequentially intercepting and passing a light beam at a regular cycle by rotatively vibrating a disk-shaped vibrating body in a casing, wherein the disk-shaped vibrating body and the casing have transparent windows through which the light beam is passed. A detection coil and an excitation coil are mounted on the inner wall of the casing, in respective positions opposite to two magnets provided on the disk-shaped vibrating body. A transistor circuit having these coils on its base side and on its collector side, respectively, is operated as the vibration generating source. Coiled springs installed between the rotation center shaft and the casing provide the repeating vibration force. The number of vibrations can be arbitrarily changed, for example, by adjusting the spring constants of the coil springs.
