IPC: G02B6/136
Filed: 1994-09-09
Abstract: Integrated optical polarization converter provided with a channel-type waveguide (B) defined by a strip-type structure (S₄) supported by a substrate (S) and consisting of a periodic concatenation of two different part strips having side walls which are at different angles with the plane of the substrate. Preferably, the two part strips then have as cross-sections either a trapezium (EFGH) with Δ₁, Δ₂ ≠ 0) and a rectangle (EFGH with Δ₁ = Δ₂ = 0), or both of them a right-angled trapezium with oblique sides situated opposite one another (EFGH with Δ₁ = 0 and Δ₂ ≠ 0, and EFGH with Δ₁ ≠ 0 and Δ₂ = 0). 
     Oblique and vertical side walls on such a strip-type structure supported by a substrate are fabricated, in the case of suitable crystal orientation, by means of two mutually complementary mask patterns, using etching steps, employing wet-chemical and dry etchants respectively.

Abstract: A tire with reduced tread noise includes a tread having a plurality of base pitches (20A-J) arranged about the circumference of the tire in at least one pitch sequence. Each base pitch in the pitch sequence has a tread geometry defined by a plurality of load-supporting tread blocks (40A-E) separated or interrupted by grooves (47,49) and/or sipes (48). The base pitches in the pitch sequence have various tread geometries, to reduce the noise of the tire on the road surface. The grooves and/or sipes in each base pitch have common end points (60,61) along the leading and trailing edges of the base pitches such that the grooves and/or sipes are continuous across the boundary between adjacent base pitches in the pitch sequence. Likewise, the grooves and/or sipes in each base pitch in one rib or row in the tire can have common end points along the edge between a base pitch in an adjacent rib or row, such that the grooves and/or sipes are continuous in the lateral direction as well. The base pitches formed in this manner can be arranged in a particular pitch sequence regardless of: (i) the individual tread geometry of each base pitch, or (ii) the particular sequence of base pitches. Moreover, the length of the base pitches in the circumferential direction can also be varied by known manners (e.g., random, sinusoidal) to further reduce the noise of the tire on a road surface.

Abstract: The system makes it possible to decrease the clearance between the rotor and the stator of a turbine (40) of a turbojet, during the various operating phases of the latter whilst keeping the temperatures of the discs within the limits of their mechanical behaviour. The discs (4) of the turbine (40) are ventilated by drawn-off high-pressure air at high temperature (2), and the stator is ventilated by drawn-off low-pressure low-temperature air (3). The respective temperatures of these two drawn-off fractions are homogenised by a heat exchanger (1). The latter is short circuited by a bypass (5) on the low-pressure circuit to make it possible to keep the clearances in the turbine (40) as stable as possible on the basis of the various speed and load conditions of the turbojet, by means of a valve (6) driven by the computer.
