    摘要: A semiconductor light emitting element is proposed that improves a light extraction efficiency without requiring any complicated processes and techniques. The semiconductor light emitting element includes an active layer for emitting first light by current injection, and a light absorbing and emitting section for absorbing a part of the first light and for emitting second light having a greater peak wavelength than the first light. A difference in peak wavelength between the first light and the second light is in a range in which a spectrum of a mixture of the first and second light maintains a unimodal characteristic or is smaller than 0.9 times a half width of the spectrum of the first light.

    摘要: The initial movement of a spherical body is detected by detecting the intersection with a light beam emitted from trigger light illuminating portion 2 to trigger light-receiving portion 3, and as a result, measurement of time by an arithmetic processing unit is started. During flight, spherical body 1 intersects light beams emitted from surface velocity sensors 4 and 5, the reflected light therein is detected by these surface velocity sensors 4 and 5, and the surface velocity of spherical body 1 is then measured. Spherical body 1 continues in flight and intersects at least two light beams irradiated from multi-beam illuminating portion 6 which are detected by multi-beam light-receiving portion 7. Based on a signal from multi-beam light-receiving portion 7 the arithmetic processing unit measures the time of intersection of spherical body 1 with a light beam, and then calculates the angle of elevation, horizontal angle, velocity and surface velocity of spherical body 1 based on the aforementioned measured time period. Furthermore, this arithmetic processing unit also calculates the amount of directional rotation of spherical body 1 based on the aforementioned calculated angle of elevation, horizontal angle, velocity and surface velocity of spherical body 1.
