摘要： There is provided a polymer or low-molecular-weight compound multilayer type organic EL device configured such that a light-emitting layer formed on a hole transport layer includes a mixture of a polymer material and a low-molecular weight material. With such a configuration, the low-molecular-weight material added to the polymer material serves as a binder filling the gap of the steric hindrance to form entanglement of the polymer material and the low-molecular-weight material. This results in that the interface between the hole transport layer and the light-emitting layer is an interface high in adhesion and also high in carrier injectability. Further, optimization of the formation conditions and materials can achieve still higher reliability and longer lifetime.

摘要： In an electric guitar, the sound produced upon playing on a string thrown, to a predetermined tension, along and over the fingerboard between the bridge and the head is checked by ear to determine phantom semitone frets with the fingerboard extended imaginarily toward and closer to the bridge and the pickup is mounted on the body at one of the phantom semitone frets. The determination of the installation position for the pickup by reference to vibrations of the string on the basis of the above principle of phantom frets not only assures an improved reproducibility of guitar sounds but enables one to obtain nearly infinite and original sounds from the electric guitar.
