Patent EP-0234624-A1 (EP)
Inventor: AARTSEN REINDER GERRIT
IPC: G02F1/133
Filed: 1987-02-02
Abstract: A liquid crystal device comprises between two supporting plates spaced apart at a distance d and having orientation layers, a nematic liquid crystal with a cholesteric addition. The mixture has a positive dielectric anisotropy and a natural pitch p such that the ratio d/p has a value between 0.5 and 1, whilst the directer due to the orientation layers shows a twist across the layer thickness d of greater than π and less than π radians, the director assuming a tilt-angle between 0° and 70° at one surface and a tilt-angle between 5° and 70° at the other surface. The voltage-transmission characteristic curve of such a device shows hysteresis. Starting from a given holding field in which the liquid crystal is in a first state, it can be switched to different (viewed macros­copically) intermediate transmission states (grey level) due to microscopic variations on the surface by means of pulsatory fields of different values whose energy content exceeds a certain threshold.
Patent EP-0260166-A1 (EP)
Inventor: COUTIN PIERRE
IPC: B64D7/08
Filed: 1987-08-06
Abstract: The body 1 has, at one end, a downstream coupling 4 intended to be connected to a use member, and it has, at its other end, a base 10 pierced with an inflation orifice 19. Inside the body 1 there is arranged a movable disc 8 fixed to a valve 5 which can be applied to a sealing seat 3 surrounding the orifice of the coupling 4. The disc 8 limits, with the bore 9 of the body 1 and the base 10, a small capacity 16 inside which is housed a pilot valve 18 interacting with the orifice 19. The opening of the pilot valve 18 under the action of the electromagnet 20 causes the pressure in the small capacity 16 to fall, which forces the valve 5 to move away from the seat 3 under the action of the pressure of the fluid. The device permits the creation of a powerful and rapid thrust exerted on objects, for example loads carried beneath aeroplanes, or alternatively protective panels. <IMAGE>

Title: Mechanical interlock
Inventor: FLIERL ERWIN ING
IPC: H01H50/32
Filed: 1988-10-14
Abstract: A mechanical interlock for two switching devices, preferably electromagnetic switching devices, is described, which interlock is intended reliably to prevent the other switching device from being switched on when one switching device is switched on. The construction of the interlock is undertaken in such a way that when one switching device is switched on, the armature (4) of the other switching device is removed further from the associated yoke by being carried along out of its position of rest, so that a reliable blocking of the connecting movement of the other armature is guaranteed. The interlock can be applied especially in contactor-reverser combinations. <IMAGE>

Inventor: ENDO MASAYUKI
IPC: G03F7/095
Filed: 1988-10-20
Abstract: The present invention provides a pattern forming method which comprises forming a material decreas­ing its ultraviolet transmittance upon exposure to far ultraviolet ray on a ultraviolet-sensitive positive type resist, selectively exposing it to a far ultraviolet ray, subsequently exposing its whole area to ultraviolet ray, and thereafter removing the film of said material and developing the resist. Alternatively, the material may also be a material increasing its ultraviolet transmittance upon exposure to far ultraviolet ray. In any of these cases, the film of said material functions as a contact mask upon the whole area exposure to ultraviolet ray, owing to which a pattern of good shape can be formed. As a substance decreasing its ultraviolet transmittance, the film of the material can contain an azide compound, a spiropyran compound or a melamine compound, for example. As a substance increasing its transmittance, the film of the material can contain a diazo compound or a nitron compound, for example. Further, a similarly good pattern can be obtained by using an acridine derivative as the material film and similarly combining ArF excimer laser and far ultraviolet ray, too.

Abstract: The subject of the invention is intended for a downwardly opening calender, on the stand of which it is supported. It is arranged on both sides of the cylinder (1) and, during operation, presses from below onto the cylinder suspensions (3) in a given position of the cylinder (1). This is effected with a force (K') which compensates for the overhanging loads (K). The force (K') in the device (5) is produced or set by a means (7) which can be moved or compressed or displaced or deformed or pressed away. 
<??>When the calender is opened, a force greater than the force set acts against the device (5) and the means (7) is moved or is itself compressed or pressed away, by which means a path of the cylinder (1) is provided into a bottom, lowered position. 
<??>The means for producing the force (K') can also be a spring assembly, an air spring or a liquid column supported on a cushion of gas and similar.

The control circuit, which is operatively connected to the valves (20, 21, 22, 27), is designed as a programme-control system. During the tapping operation, only the through-way valve (20, 21, 22) of that line (17, 18, 19) leading from the compressed-gas source to that storage container (1, 2, 3) being tapped is open.
