Patent EP-0632380-A1 (EP)
Inventor: MIFSUD JEAN-PAUL
IPC: G11C29/44
Filed: 1993-06-30
Abstract: There is described a novel circuit that identifies the defective redundant word lines in the memory unit of a state of the art SRAM macro including an ABIST structure and a redundancy mechanism. The novel circuit (41) combines existing signals: the selection signals R1 to Rq, the RESULT and the COMPOSITE RESULT signals that are generated as standard in such macros. The selection signals R1 to Rq indicate whether or not a redundant word line has been selected. The RESULT signal indicates whether or not the memory unit at the address being tested is defective after a READ operation. The COMPOSITE RESULT signal indicates that the number of fails detected exceeds the number q of redundant word lines. All these signals run on a cycle per cycle basis. According to the invention, the selection signals R1 to Rq are applied to a q-way OR gate (42) whose output is connected to a latch (43). The signal which is output by the latch and the RESULT signal are ANDed in a 2-way AND gate (44). The signal (RLBU**) which is generated by the AND gate (44) indicates whether or not the redundant word line that was used is defective. In a preferred embodiment, this signal (RLBU**), and the COMPOSITE RESULT signal are applied as inputs to a 3-way OR gate (26'), whose output is connected to a self-maintained latch (27), referred to as the "not fixable" latch. The third input of said 3-way OR gate is connected to the "not fixable" latch output. If there is a fail on a redundant word line, the "not fixable" latch is set to indicate a non repairable state of the SRAM macro memory unit. As a result, a two-pass fuse blow process is now made possible, which significantly increases the manufacturing yields and repairability of said SRAM macro.

Abstract: The mechanism comprises a winding reel (1) on which is fixed one end of the cord to be wound. This reel comprises a smooth part (8) of greater diameter than the initial diameter of the reel (1), situated at a distance from the point of attachment (12) of the cord and limited by a shoulder (9). The cord (11) to be wound is guided approximately tangentially to this shoulder in such a way that the windings (11a) formed on the part of greater diameter are pushed back by the shoulder (9) under the effect of the load, the length of the part of greater diameter (8) being such that, in the windings (11b) leaving this part of greater diameter, the traction on the cord is zero. These loose windings position themselves alongside one another on the part (1) of the reel ensuring a uniform winding without overlapping of the cord. <IMAGE>

Abstract: The invention relates to a method and to an arrangement for demodulating a signal (f) preferably frequency modulated with digital information, and then particularly a frequency shift modulated signal, with a frequency counter detector (16) which directly produces a digital value representative of the instantaneous frequency of the frequency modulated signal. In order to obtain the lowest possible uncertainty in frequency detection at unchanged counter frequencies (f r ), the frequency modulated signal is mixed down to a difference frequency (f 3 ) which is insignificantly higher than the sampling frequency (f s ) required to extract the modulation information from the instantaneous counter value (N 2 ). The frequency counter detector begins a counting sequence during each of the periods of the difference frequency.

Title: An olefins process which combines hydrocarbon cracking with methane coupling.
Inventor: CALAMUR NARASIMHAN
IPC: B01J19/24
Filed: 1992-12-21
Abstract: An olefins process is described which combines cracking of a hydrocarbon feedstock with the coupling of methane using an oxygen-affording gas such that the heat evolved in the exothermic methane coupling reaction is effectively transferred to the endothermic cracking process in a manner which does not allow the non-hydrocarbon products in the effluent of the methane coupling reaction to mix with the effluent of the cracking process. By combining the cryogenic requirements of the two processes, the refrigeration used in air liquifaction to separate oxygen for the methane coupling process can provide refrigerant nitrogen to liquify one or more of methane, ethylene and propylene which can be used in the cryogenic separation of the C2+ hydrocarbon products in the cracking process effluent.

Two moving connecting rods (25, 26) actuated by a cylinder (2), shift a cradle (20) supporting the user under the armpits. The user controls the lowering, stopping or raising manoeuvre by operating a control having handles (9) which are placed in front of the cradle. The force necessary for these manoeuvres is provided by pressure of water from the main supply acting on the cylinder piston (2) before falling again into the cistern for normal use. The hydraulic connection is made by fitting a special joint (17) in place of the existing tap. The arm-cradle assembly can be folded and blocked in a high position, for normal access to the lavatory. The device can be used in hospitals, homes for the elderly or the sick, rehabilitation centres, or it can be rented out.

Date Dec. 23, 1993Methods and apparatus for engine retardation in multi-cylinder combustion engines are disclosed including a hydraulic clearance regulator for regulating the clearance in a valve controller in response to a hydraulic fluid pressure below a predetermined maximum value in which the angular position of the crankshaft of the engine at which the exhaust valve in one of the engine cylinders is operated by an extra ridge on the camshaft is determined by the clearance in the valve controller. A pressure relief valve maintains the hydraulic fluid pressure below the predetermined maximum value, and a controller gradually reduces the clearance towards zero while the hydraulic fluid pressure in the valve controller is maintained below the predetermined maximum value so that the risk of operating the exhaust valve during a cylinder pressure greater than a predetermined elevated cylinder pressure is substantially reduced.
