    摘要: A semiconductor light emitting device is disclosed. An emitting layer forming portion for forming an emitting layer made of a compound semiconductor of AlGaInP group or AlGaAs group including a n-type layer, an active layer and a p-type layer laid one on another is formed on a GaAs substrate. Further, a current diffusion layer of GaP is formed on the front surface of the emitting layer forming portion. The p-type layer between the active layer and the current diffusion layer is formed to the thickness of not less than about 2 &mgr;m, or the current diffusion layer is formed to the thickness of about 3 to 7 &mgr;m. As a result, the semiconductor light emitting device of a high luminance is thus realized, in which the distortion due to the lattice mismatch has no effect on the emitting layer.

    摘要: A light emitting layer forming portion is formed of an AlGaInP-based compound semiconductor and having an n-type layer and a p-type layer to form a light emitting layer on the substrate. A large bandgap energy semiconductor layer is provided on a surface of the light emitting layer forming portion to constitute a window layer. A buffer layer is interposed between the light emitting layer forming portion and the large bandgap energy semiconductor layer to relieve lattice mismatch of between the light emitting layer forming portion and the large bandgap energy semiconductor layer. The interposition of this buffer layer provides a light emitting device that is high in light emitting efficiency and excellent in electrical characteristics without degrading the film property of the window layer.

    摘要: A MIDI apparatus and a MIDI system wherein an operation ON signal for starting operation to a MIDI instrument and an operation OFF signal for stopping the operation are obtained and supplied to the MIDI instrument in response to a MIDI format signal included in a subcode signal generated during play of a record medium play apparatus. If the play state of the record medium play apparatus becomes discontinuous, such as a pause after the operation ON signal is supplied to the MIDI instrument and before the operation OFF signal corresponding to the operation ON signal is obtained, the operation OFF signal is forcedly supplied to the MIDI instrument. Thereby such the sound of the MIDI instrument is stopped when there is a discontinuous play state after the operation ON signal is supplied to the MIDI instrument and before the operation OFF signal corresponding to the operation ON signal would ordinarily be supplied.

    摘要: It is known that a sectional shape of a spring wire can be formed into an oval made by a semicircle and a semiellipse. However, it has been found that such a shape is not the best obtainable, and that stress distribution can be improved by increasing the diameter of the spring wire slightly in a portion where the stress is greatest, along the semielliptical surface. Parameters are disclosed for determining dimensions that result in increased energy efficiency.
