Polypeptides are expressed by the pituitary-tumor-transforming-gene, formerly known as pituitary-tumor-specific-gene, and nucleic acids encode them. Each shell body includes a main body and a color ring arranged around a circumferential edge at an end of the main body, and a color of the color ring is different from a color of the main body. The first transport unit is configured to transport the defibrated material after being defibrated by the dry type defibrator unit. At runtime, the poses are interpolated by using key variables which are input into the polynomials as different states, for example the turning speed of the player wearing the material, which may comprise a cloth jersey. It is constructed of light weight materials, minimizing the mass but is given the ability to run at high speed in spite of vibrating environments, supply line condensation, contaminants and various attitudinal mounting by the anti-seizure insert bearing inserted into the distributor and sleeving the rotating shaft. An organic EL element in which an organic functional layer including at least one or more light-emitting layers is arranged between a first electrode and a second electrode, wherein the organic functional layer includes a bipolar charge generation layer which generates electrons and holes, and one of the first electrode and the second electrode is a hole-receiving electrode.
