Abstract: Multi-layer footwear formed of laminated layers (20, 22, 26, 28, 34) of material which are sealed together with a polymeric glue used in the original manufacture of the footwear to secure the various layers of material together. The layers of material held together by polymeric glue are capable of being heated to a degree at which the footwear, when placed in a vacuum bag or compression chamber, is molded to adopt the shape of the foot inside the footwear under atmospheric pressure once pressure inside the bag is reduced or pressure in the compression chamber is increased. The footwear is heated to the point where the synthetic components of the layers of material are flexible under thermoforming conditions, but within a temperature range in which the polymeric glue continues to perform as an adhesive so that the sealed laminated surfaces do not separate. A polymeric glue is used because it can secure the laminated layers of material together during manufacture of the footwear and continue to perform as an adhesive during heating and cooling of the laminated layers of material in a custom-molded condition.

Abstract: Metallised support based on polymethylpentene and process for the manufacture of this support. This support comprises at least one layer (2) of poly(4-methyl-1-pentene) or PMP, whose thickness is greater than 100 micrometres and at least one of whose two faces is covered, at least partially, with a metal layer (4, 6). To produce such a support, a metal layer is plated with heating, by pressing or laminating, at a temperature at least equal to the melting temperature of the PMP employed, onto a layer of PMP (of slightly greater thickness than that which it is intended to obtain once the metallisation is finished), after a surface treatment of these layers has been carried out, which is capable of promoting their adhesiveness. Application to the production of very high frequency electronic circuits and planar aerials. <IMAGE>

Inventor: BREUGNOT FREDERIC
IPC: G05F3/24
Filed: 1990-10-18
Abstract: The invention relates to integrated circuits, and more particularly the manner of producing in these circuits a constant current source which is stable as a function of temperature and of the supply voltage of the integrated circuit. 
<??>According to the invention, it is proposed to produce a stable current source on the basis of two transistors (Q1, Q2) in parallel, one controlled by a reference voltage source of the "band gap" type (AO, R1, R2, R3, D1, D2) and the other by a wilson mirror (T1, T2, T3, T4). The addition of the currents from the two transistors gives a current which can be much more stable in terms of temperature than the individual currents in each of the transistors.
