Patent EP-0445720-A2 (EP)
Inventor: KAPFHAMMER KARL
IPC: G02F1/163
Filed: 1991-03-05
Abstract: When applying an operating electrical voltage to conductive layers of a system of electro-optic layers the problem exists that for some applications the targeted change in the optical state of the system of layers proceeds too slowly. It is proposed for the purpose of acceleration to select an external potential difference for terminals of the conductive layers that is initially greater than a permissible limiting value for an internal potential difference of the system of electro-optic layers, and only then to step down to or below the limiting value. As a result, voltage drops in the conductive layers are compensated during (dis)charging currents of the system of electro-optic layers, and (dis)charging of the system of electro-optic layers is accelerated without its limiting voltage value being exceeded. The external potential difference can be initially exceeded depending on fed-back actual values of the internal potential difference, or in a timed fashion. Preferred applications are, e.g., electrochromic wafers.

Abstract: A safety device for limiting axial operating loads which are exerted on a drive worm of a machine, such as a platen press, including a pressure chamber receiving a first piston connected to an auxiliary shaft, which is axially shiftable and non-rotatable, and is connected to one end of a main shaft of the drive worm. Fluid pressure in the pressure chamber holds the piston in a first position to maintain the axially displaceable connection of the other end of the main shaft to a drive shaft. In response to an axial overload, the pressure in the pressure chamber is relieved to eliminate the holding feature to allow the main shaft to shift axially to disengage it from the drive shaft. The safety device includes a second piston for moving the first piston to the first position where the drive shaft and main shaft are recoupled when the machine is in a rest position.

Abstract: An adjustable switched capacitor circuit comprises a first stage 201, a second stage 202 and a switched capacitor circuit 204 coupling the output of the first stage 201 to the input of the second stage 202. The operating parameters of the second stage 202 are a function of the effective resistance of the switched capacitor coupling circuit 204. An attenuator 208 interposed between the output of the first stage 201 and the input of the switched capacitor coupling circuit 204 controls the charging voltage of the switched capacitor coupler 204, thereby controlling its effective resistance and parameters of the output stage 202. The signal loss through the attenuator 208 is infinitely adjustable in response to an external control voltage to obtain continuous control of various output stage parameters. The output stage 202 may comprise a filter having the parameters of its transfer function determined by the effective resistance of the switched capacitor coupling circuit 204.

Abstract: A test fixture for a high pin count surface mounted IC device has a test head assembly connected to an adapter having electrically conductive elements that couple the output of the IC device to test points on the test head assembly. The test points are coupled to conductive pads on the test head assembly via conductive runs. The test head assembly conductive pads mate with conductive pad formed in the electrically conductive elements of the adapter. The conductive elements engage leads on the IC device providing conductive paths between the IC leads an the test points on the test head assembly. The test fixture is secured to the IC device by friction forces between the periphery of the IC device and the inner surface of the adapter. The test fixture or the adapter is usable as a low profile chip carrier by inverting the fixture or adapter and as a circuit board interconnect.

Abstract: The invention relates to a percussion mechanism for a drill string, having a percussion piston which is guided in a housing and moved to and fro under the action of a pressurised hydraulic medium. 
<??>In order to be able to act upon the drill string in different directions with percussion energy, if necessary, the invention proposes to design the housing (3) to be open on both sides in the longitudinal direction of the percussion piston (4) and to provide the latter with a passage bore (4b) into which the drill string (2) projects, at least with a part of its overall cross-section. Said drill string has a meeting face (9a) which can be acted upon by the percussion piston (4) and can be handled in such a way that the percussion direction of the percussion piston is reversible by transferring the percussion mechanism (1).

Abstract: A carry propagation circuit (3) generating a block carry propagation function P as a signal at an intermediate junction of a carry lookahead circuit, on the basis of input two numbers A and B, and a carry generation circuit (4) for generating a block carry generation function G on the basis of the two numbers A and B, are provided. When a carry input is 0, a carry c₀ is the same value to the block carry generation function G. On the other hand, when the carry input is 1, the carry c₁ is an OR of the block carry generation function G and the block carry propagation function P, which can be obtained by an OR circuit (5). Two sums S₀ and S₁ are derived from two carries and an exclusive OR of two numbers A and B by exclusive OR circuits (6,7). 
The circuit can be used in a carry-select adder or in an absolute difference calculating circuit.

Abstract: Method for multiplying the speed-resolution product of a raster scanning or imaging device such as an inkjet printer, and a resulting pixel image data structure, are disclosed. Illustratively, a 300-dot per inch (dpi) by 600-dpi logical pixel image is mapped (14) to a corresponding, non-overlapping physical dot image, and the printer's inkjets are fired (22) responsive to the dot image to direct generally spherical ink droplets onto paper at 600-dpi resolution grid timing in order effectively to double the horizontal resolution of the printed pixel image, without increasing the firing rate of the print head. In order to accomplish this, and to avoid ink dot overlap, the printable pixel image is thinned (18, 20) before it is printed (22) by a method that leaves no visible horizontal or vertical gaps by selectively turning off pixels within a 'black' image that were on and that otherwise would result in ink dot overlap and slower print head speeds were the inkjets cycled at 600-dpi resolution timing. Pixel thinning (18, 20) is performed substantially without adversely affecting pixel image edge definition.

Abstract: Method consisting in treating the lasting (lit. mounting) margin of the shoe when mounted on its corresponding last with polyurethane polymers which react during the shoe fabrication process (between the stages of laying (lit. mounting) and of joining of the sole). These polymers crosslink by themselves or under the effect of catalysts within the leather, when heated or simply when kept for a certain period at room temperature; this crosslinking has the effect of strengthening their fibre structure and improving the cohesion between the layers of leather. As a result the operation of scouring and roughing is no longer necessary to be sure of adequate joining of the sole to the shoe upper. This method offers great advantages in that by eliminating the conventional operation of scouring or roughing it enables labour to be cut back, the process then being readily automatable; and the quality and appearance of the finished articles to be improved.

Abstract: The quality of a double yarn is essentially judged on how regularly the length of the individual yarn components of the double yarn are embedded therein. In order to detect irregularities in length of the individual yarn components of a double yarn, a method and apparatus are proposed in which method or apparatus the double yarn is guided in its longitudinal direction at a constant speed between an optotransmitter and an optoreceiver of an optoelectronic measuring and evaluation device which reacts to changes in the double yarn structure in the longitudinal direction and emits an output signal whose temporal variation represents a function of the scanned changes in structure, so that this output signal can be analysed and examined for periodic components and from this the double yarn period and/or further parameters characterising the structure of the double yarn can be determined, a slit diaphragm being inserted before or after the double yarn into the beam emitted by the optotransmitter and the slit of this diaphragm being inclined relative to the direction of motion of the double yarn, preferably parallel to the angle of twist alpha  of the double yarn to be examined. <IMAGE>
