Patent EP-0024913-A1 (EP)
Inventor: SOWTON GEORGE EDGAR
IPC: A61N1/36
Filed: 1980-08-26
Abstract: A dual electrode for use in cardiac pacemaking to enable both ventricular and atrial electrical contact to be made. The electrode is formed as a catheter (4) for passing through a blood vessel to the heart and has a ventricular electrode at its distal end. Spaced back from the distal end are one or more atrial electrodes (2) in a plane transverse to the catheter and spaced radially apart therefrom. The or each atrial electrode is supported in a material (14) sufficiently flexible and resilient to enable the atrial electrode(s) to distort out of the plane and pass through the blood vessel. The atrial electrodes may be formed as separate prongs, or a single continuous electrode may be formed (to resemble a small floppy disc). Means such as springs (12) may be provided to increase the resilience of the material (14) supporting the atrial electrodes (2).

Abstract: L'invention a pour but de fixer, dès la première opération de masquage, la position et les dimensions de la grille d'un transistor à effet de champ, ainsi que les intervalles entre source et grille, grille et drain. A cet effet, on réalise un masque comportant des fenêtres de source, grille et drain, en utilisant un premier matériau (3), isolant ou semi-isolant, puis on comble les trois fenêtres à l'aide d'un deuxième matériau (5). On dépose les contacts ohmiques de source (81) et de drain (82) dans les fenêtres correspondantes réouvertes par attaque sélective du deuxième matériau (5) effectuée après masquage de la partie de la couche (5) située au-dessus de la fenêtre (32) non réouverte. Une deuxième attaque sélective après masquage des contacts (81) et (82) permet de déposer un contact de grille de type Schottky. Application aux transistors à effet de champ à très haute fréquence.

Abstract: A spark plug (60, Fig. 4) for an internal combustion engine comprises a ceramic body (31) and a plurality (e.g. three) of spark electrodes (34) which receive high-tension electricity independently of each other via electrical conductors extending through the ceramic body. Each spark electrode (34) has a tip region which extends away from the plug axis in the vicinity of the end of the plug so as to define with a respective counter-electrode (40) of the plug a spark-gap (42) which is substantially parallel to the axis of the plug. Preferably the spark gaps (42) are substantially equiangularly spaced around the plug axis. 
     The spark plug of the invention enables an internal combustion engine to be operated with increased thermal efficiency compared to a conventional single-gap plug, and with an improved fuel economy which increases as the air-fuel ratio increases, whereby the engine may be operated on a fuel of reduced octane number (e.g. with low lead or lead-free gasoline) and/or with an increased compression ratio.
