Abstract: A small Faraday rotator is placed in the inner space of a receptacle and a holder. Because the plane of polarization is rotated, even when backreflection light returns to a laser diode, the lasing state does not become unstable. Being placed in the inner space and fixed there, the Faraday rotator can be small and therefore does not increase the part cost notably. The assembly cost does not increase, because it is not required to tightly press-fit a member into a narrow hole.

Abstract: Round honeycomb rotor for wind generators and most propellers has bent tubular trapezoids, two or more concentric tubular cylinders and a variable number of round bent tubular trapezoids. Both cylinders and trapezoids form modular trapezoidal tubes, which have large wind contact surfaces. The concentric tubular cylinders of the round panel have bent pieces fitted in between them whose function is to minimise wind exit and multiply wind contact surfaces in wind generators. As for propeller rotors the number of round bent tubular trapezoids gets multiplied as well as its wind contact surfaces, which results in the optimum use of most centrifugal propelling forces thanks to the reduction of wind entrance and the amplification of wind exit.
