Thyristor Un article de Wikipédia, l'encyclopédie libre. Les premiers thyristors commerciaux sont sortis en 1956. Leur capacité à commander une grande quantité de puissance et de tension associée à une grande compacité leur a permis de trouver de nombreux champs d'applications dans l'électronique de puissance : ils servent ainsi dans les convertisseurs statiques tels que les gradateurs, les redresseurs pilotés, les onduleurs, pour la commande des moteurs électriques, que ce soit dans l'industrie, le ferroviaire, l'avionique ou l'automobile, pour les lignes électriques HVDC, etc. Ils sont particulièrement adaptés quand la puissance est élevée mais la fréquence basse. Les thyristors classiques se servent du passage par zéro du courant pour s'ouvrir, cela les rend inutilisables seuls pour la commande de courant continu. Des modifications de structure permettent d'ouvrir les thyristors grâce au signal de la gâchette, par exemple dans le cas des GTO. Symbole électrique d'un thyristor.

Mitología japonesa Una de las hijas del rey dragón que vive en el fondo del mar. Utagawa Kuniyoshi (歌川国芳) (1797–1861). Los mitos japoneses convencionales se basan en el Kojiki, en el Nihonshoki y algunos libros complementarios. El Kojiki que literalmente significa "registro de cosas antiguas" es el libro más viejo reconocido sobre mitos, leyendas, y la historia de Japón y el Nihonshoki es el segundo más antiguo. El Shintoshu explica orígenes de deidades japonesas desde una perspectiva budista mientras que el Hotsuma Tsutae registra una versión diferente sobre la mitología. Un resultado notable de la mitología japonesa es que explica el origen de la familia imperial, y les representa como descendencia divina. Escritura de los nombres propios[editar] Muchas deidades aparecen en los escenarios de la mitología japonesa, muchos de ellos tienen múltiples alias y además algunos de sus nombres son muy largos. hu está modernizado como fu.zi y di están modernizados como ji.

Mitología japonesa No soy ningún experto en mitología japonesa, pero siempre ha sido un tema que me ha interesado mucho, así que me decidí a realizar un pequeño artículo sobre el tema basándome en los libros “Dioses y Mitos Japoneses” (varios autores), “Mitología japonesa” (M. Anesaki) y “Mitología” (varios autores). Todos ellos hacen referencia a lo revelado en el Kojiki, el primer documento escrito que se conoce en Japón. El nacimiento del Japón En el principio, tras la formación del cielo y de la Tierra, tres dioses se crearon a sí mismos y se escondieron en el cielo. Izanagi e Izanami fueron encargados por los demás dioses de formar las islas japonesas. Descubrieron que sus cuerpos estaban formados de manera diferente, por lo que Izanagi preguntó a su esposa Izanami si sería de su agrado concebir más tierra para que de ella nacieran más islas. En lugar de parir una isla, Izanami dio a luz a un malforme niño-sanguijuela al que lanzaron al mar sobre un bote hecho de juncos. El más allá El engaño de Susano
Shinto Rituals Shinto rituals are a central component of most of the national festivals in Japan, as well as of the more specialized events at particular shrines and other sacred sites. Most often they are performed by male priests who are assisted by a female shrine functionary called a miko, who often is a shaman. The most common type of ritual involves purification - symbolically purifying oneself or an object before interacting with the kami (Shinto gods). Shinto rituals are usually just one part of a type of large public festival called a matsuri, which is the main kind of celebration in Shinto. Other Shinto rituals are performed during smaller, more local or even private festivals. Finally, there are common rituals performed by individuals when they visit shrines - ritual washing, making offerings, clapping hands, and bowing. Important to remember here is that all these rituals are designed for communication with the gods, or kami.
