Title: Generator comprising phase-reverse two-stage impeller and inside and outside double rotors
Inventor: KANEMOTO TOSHIAKI
IPC: H02K19/16
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To simplify a generator by removing a nozzle or a guide vane for giving an angular momentum to the fluid flowing in an impeller, and also, reducing the outside diameter of the generator, as regards the generator utilizing fluid energy. SOLUTION: Axial inflow and outflow are materialized by generating impellers 11 and 12 on front and rear stages in reverse directions to each other without providing a nozzle or a guide vane, and generating a change of angular momentum in the fluid passing between both impellers. The outside diameter of the generator is halved as compared with a conventional one by transmitting the rotating power obtained from the change of angular momentum at this time to rotors 7 and 8 double inside and outside, and doubling the relative velocity between both rotors.

IPC: H01L31/10
Filed: 1986-04-14
Abstract: PURPOSE:To prevent the change in a light reception efficiency due to the angle of expansion of an emitted light and thereby to stabilize the light reception efficiency, by forming a light-receiving surface as a concave spherical surface. CONSTITUTION:A light-receiving surface 12 is formed to be a concave spherical surface. By setting the light-emitting point of a light-emitting element 11 such as a semiconductor laser element at the focal point of said light-receiving surface 12, all laser beams emitted from the light-emitting element 11 are caught by the light-receiving surface 12, on condition that the angle of radiation of the laser beams emitted from the light-emitting element 11 is smaller than an angle formed by the light-emitting element 11 and the light-receiving surface 12, and therefore a light reception efficiency does not change even when said angle of radiation changes. Besides, even when the angle of radiation of laser beams emitted from the light-emitting element 11 changes, the light reception efficiency does not change, since the emitted beams become spherical waves and fall vertically on the light-receiving surface 12.
