Patent EP-0060726-A3 (EP)
IPC: F02K9/88
Filed: 1982-03-16
Abstract: A gas thruster system particularly suited for use in 
controlling the flight of an aerial projectile, has self-center­
ing valve means controlling the exhaust of gas from a pair of 
oppositely directed exhaust nozzles. Actuating means, 
which may comprise a pair of solenoids, are adapted for co­
operation with the valve means and, in operation, shift the 
valve means to either side of a null central position towards 
closing one or the other of the pair of nozzles to provide 
differential gas flow from the pair of nozzles whilst main­
taining a substantially constant area vent from a gas source.

Title: Arrangement for the external modulation of radiation emitted by a high-performance co2 laser
IPC: B23K26/064
Filed: 1985-06-07
Abstract: The invention relates to an apparatus for external modulation of high-efficiency CO2 laser beams of defined wavelength, particularly for use in CO2 laser material working apparatuses. According to the invention two plates made of transparent material are arranged parallel to each other, the inner surfaces of the plates are reflective and the outer surfaces are non-reflective. The two plates are mounted so that one of the plates is rigidly connected to a massive oscillation-resistant base which comprises a strong permanent magnet, and that the other plate, together with a special hollow cylinder, is fastened on an elastic membrane, so that an oscillatable system is formed which, on the one hand, is driven by the electro-magnetic interaction between the permanent magnet and a coil and that the system, on the other hand, is damped by means of the frictional force of a suitable damping medium of high viscosity located in a gap between the stationary and the oscillating subsystems, so that a reproducable adjustment of the setting of the gap's width between the two plates is possible via the control current of the coil.

Title: Identity card with a visually detectable authenticity feature, and method of making it
IPC: B42D25/41
Filed: 1986-10-03
Abstract: Information is provided in a multilayer identification card by means of a laser beam. This information is recorded by irreversibly changing (blackening) transparent synthetic material. Synthetic materials which blacken at different intensity values are used for the individual card layers. By controlling the laser beam intensity, information can thus be recorded only in one layer or else simultaneously in several layers. If the layer arrangement, layer materials and recording parameters (intensity, writing width, etc.) are selected appropriately, images can be produced which change their appearance when the viewing angle is changed. The various visual effects which can thereby be otained serve to distinguish the authenticity of the identification card.
Patent EP-0219100-A3 (EP)
IPC: H01L21/3065
Filed: 1986-10-14
Abstract: The present invention relats to a method of forming a fine 
pattern. First, an object (13) to be etched, such as a metal film 
formed on a semiconductor substrate (11), is prepared. On the 
object (13), predetermined etching masks (16-1, 16-2) of or­
ganic material are formed, with which the object (13) is etched 
to obtain a predetermined pattern, such as wiring patterns 
(18-1, 18-2). In addition to the etching masks (16-1, 16-2), a 
dummy etching mask (17) of organic material is formed on the 
object (13), such that it does not affect the operation of the 
predetermined circuit. The sum of the areas of the etching 
masks (16-1, 16-2) and dummy etching mask (17) is deter­
mined such that it is greater than the value determined by the 
material of the object. If the object is fomed of Aℓ-Si, for ex­
ample, the sum of the areas should be larger than 30%. Using 
a both the etching masks (16-1, 16-2) and the dummy etching 
mask (17), the object (13) is etched by a reactive ion etching 
technique. Since the sum of the areas ofthe masks (16-1,16-2, 
17) is larger than the predetermined value, a protection film 
(20) is formed during the etching step, and this protection film 
(20) prevents the object (13) from being etched in the lateral 
direction. Therefore, the object (13) is prevented from having 
an undercut, or the like.

Abstract: A content addressable memory includes a 
memory cell (36) connected at each crossover point 
between rows (32) and columns (34, 36) of conductors to 
define first (26) and second (28) arrays of memory 
cells wherein the data stored in the second array 
includes the complement of that stored in the first 
array. In an associative mode of operation, an input 
code is applied simultaneously to all of the columns 
of the first and second arrays of memory cells. The 
existence of a match between the input code and a key 
forming a part of a stored data word is recorded as 
logical states on the rows of conductors which 
indicate the location in memory of the data word in 
which a match is achieved, In a conventional RAM mode 
of operation, data can be written (16b) into or read 
(16a) from the first memory array.
