Title: Sistema para modificar la frecuencia de vibración de las lengüetas libres de forma  reversible y regulable
Inventor: TERMES SERRA GERARD
IPC: G10D9/02
Filed: 2014-12-23
Granted: 2017-04-11
Abstract: Sistema para modificar la frecuencia de vibración de las lengüetas libres de forma reversible y regulable. La lengüeta libre es el elemento generador de sonido de los instrumentos musicales llamados aerófonos de lengüeta libre, que comprenden el acordeón diatónico, acordeón cromático, bandoneón, concertina, armónica, melódica, armonio y algunos órganos. El invento se basa en el hecho de que cuando una lengüeta libre está afectada por un campo magnético la frecuencia de vibración de ésta cambia. Un elemento que regula y ajusta este efecto en cada lengüeta permite realizar un mantenimiento de la afinación de los instrumentos sin desgastar las lengüetas y más rápido y preciso que en el estado de la técnica actual. Un conjunto de elementos que ajustan este efecto en el conjunto de lengüetas de una voz aporta prestaciones inexistentes en el estado de la técnica actual de los instrumentos de lengüeta libre como un registro de trémolo regulable o un teclado dinámico en cuanto al trémolo. Un conjunto de elementos que ajustan el efecto en las lengüetas de todas las voces aporta un pequeño efecto de portamento o la posibilidad de ajustar la afinación global del instrumento.#La fuente del campo magnético puede ser un imán permanente, siendo los elementos de ajuste del efecto elementos mecánicos tales como tornillos palancas, guías u otros que regulan la distancia entre los imanes y las lengüetas o desplazan un elemento ferromagnético que actúa de obturador del efecto. La fuente del campo magnético en algunos casos también pueden ser electroimanes, siendo los elementos de ajuste elementos eléctricos tales como resistencias variables que regulan la fuerza de los electroimanes.

Title: Method for vulcanization an elastomer
Inventor: ARIMATSU TOSHIO
IPC: B29C35/02
Filed: 1981-11-13
Granted: 1990-03-12
Abstract: An elastomer is vulcanized by a mixt. of a high pressure low enthalphy gas and a low pressure high thermal capacity fluid.  The mixing may be effected externally or within the vulcanizing chamber and is under the control of a controller to ensure preset pressure and thermal parameters are maintained.

Title: Method of providing raised electrical contacts on electronic microcircuits
Inventor: VANDEPAS HERMANUS A
IPC: H01L23/485
Filed: 1982-03-18
Granted: 1990-09-27
Abstract: The mechanism applies " contact bumps" to a conductive layer (2) on a semiconductor substrate (1). A wire (5) made of a conductive material with a low melting point is fed through a capillary tube (4) in a heated nozzle (3). When a ball (6) has been formed on the end of the wire, the nozzle is lowered until the ball is squashed out to form a round flat "bump". When the bump has cooled slightly, the nozzle is raised by a distance equal to two or three times the wire diameter and moved 1.5 to 2 times the wire diameter to the side, causing a "kink" in the wire. The nozzle is then lowered to press the kinked portion of the wire into the bump. The nozzle is then raised and the wire breaks off. The temperature and nozzle movements are controlled by a microprocessor.
