Patent FR-2644665-A1 (FR)
Inventor: MELLUL SYLVIE
IPC: H05K3/12
Filed: 1989-03-16
Abstract: The method of producing a means of electrical connection, particularly interconnecting substrates for hybrid circuits, involves the deposition of a layer of untreated ink on a highly heat- dissipating support such as aluminium nitride, followed by a preliminary drying of the ink at a temperature of the order of 100 DEG C to 150 DEG C. This is then followed by firing consisting of
 (a) an elevation in temperature incorporating a phase for the removal of the polymer resins,
 (b) a sintering stage at a temperature of the order of 600 DEG C to 1000 DEG C and
 (c) a delayed cooling. The characteristic feature is that the atmosphere during the stage at which the polymer resins are removed has a low oxygen content lying between 100 ppm and 5000 ppm, whereas the oxygen content of the atmosphere during the high temperature sintering and of the cooling atmosphere must be below about 10 ppm.

Title: Single-seed pneumatic distributor (dispenser) for a seed drill making it possible to sow seeds of different sizes
Inventor: RENE ECOLASSE GUY LOUIS EUGENE
IPC: A01C7/04
Filed: 1991-07-03
Abstract: Single-seed pneumatic distributor with discs for a seed drill for sowing seeds of different sizes including 2 perforated discs 30 and 32 placed on one another and fixed to the tubes 36 and 33 placed one inside the other in order to allow the discs 30 and 32 to pivot through a certain angle. The tube 36 is secured to the female splined shaft 35 sliding over the male splined driveshaft. An adjustment allows the angle between the 2 discs 30 and 32 to be modified, which will be brought about by causing the tubes 36 and 33 to pivot by fixing to one of the ends of the arms 28 and 27, themselves fixed at their other end via ball joints 37 and 29 to moving arms 39 and 40, of which their other end is equipped with nuts 41 with a right-handed thread and the other with a nut 42 with a left-handed thread. These nuts can move, being placed on a threaded rod, one of these rods being right handed and the other left handed. This threaded rod, by rotating via the crank 4 will displace the arms 40 and 39 as well as the arms 27 and 28 which, by pivoting, will modify the angle between the two discs thus modifying the position of the holes on the disc 30 with respect to the disc 32, which will make it possible to obtain a wide setting range for sowing seeds of different magnitudes.
