Title: Method and device for cleaning, polishing and careening boats, afloat
IPC: B63B59/08
Filed: 1987-03-26
Abstract: The invention, with a rapid and inexpensive system of use (in comparison with currently existing systems making it necessary to land the boat) has the object of passing as many boats as possible through the "floating station" in one same port, whilst remaining afloat. The device implemented for these various works is as follows: a U-shaped floating hulk with great buoyancy constitutes the operational area. A lifting system with two submerged "cradles" makes it possible to clear the plane of flotation by 15 to 50 cm in order to proceed with cleaning the boatwork (upperworks). On each inner face of the longitudinal hulks there is fixed a rail on which there slides an articulated movable arm moved automatically, hydraulically, mechanically or electrically equipped with brushes, polishing felts or pressure jets. After having relowered the cradle system which remains under the boat, one proceeds with cleaning the underwater hull using the articulated movable arm. The polishing brushes are replaced by pressure jets.

Title: Thyristor de protection a gachette auxiliaire
Inventor: JEUDI PATRICE
IPC: H01L29/747
Filed: 1987-07-03
Abstract: L'invention concerne les composants semi-conducteurs de protection, thyristors ou triacs. Ces composants ne comportent normalement pas d'électrode de gâchette et sont déclenchés par une surtension entre les électrodes principales. Pour les cas où on désire quand même avoir aussi un déclenchement par un courant de gâchette, l'invention propose une structure avec région de gâchette rétrécie (partie D) et région centrale surdopée 22 sous une partie de l'émetteur 18. Par cette structure, on évite d'avoir un courant de gâchette trop important pour déclencher le thyristor et un courant de maintien trop faible une fois qu'il est déclenché.
