Abstract: The invention provides a composite material specifically adapted for use as high temperature corrosion resistant electrical connectors. A conductible nickel-base substrate alloy having corrosion resistance, strength and creep resistance is used to hold shape at 200°C. An interlayer of substantially pure nickel is electrolytically plated over the nickel-base substrate. A noble metal surface is diffusion bonded to the electrolytic nickel interlayer. The noble metal surface cannot be hardened by organic additives which accelerate corrosion at 200°C. Alternatively, if a copper-base substrate is used, a layer of wrought pure nickel is bonded to the substrate then a layer of electroplated nickel is used to overplate the wrought nickel and the copper-base substrate. A noble metal surface is then diffusion bonded to the electrolytic nickel layer.

Abstract: Testing of an integrated circuit, configured of a plurality of flip-flops at least a portion of which are arranged in a scan chain (16₁ - 16   k   ), is carried out by replacing each self-looping, non-scan chain flip-flop with an initializable non-scan flip-flop. The integrated circuit, including each initializable flip-flop therein, is then initialized prior to placing the integrated circuit in a non-operational mode. During the non-operational mode, a first test vector is shifted through the scan chain flip-flops, causing each to shift out a bit previously latched therein. The integrated circuit is then returned to an operational mode, after which time, a second test vector is applied to its inputs, causing a response to appear at its outputs, and also causing a bit to be shifted into each scan chain flip-flop. The response of the integrated circuit is compacted with the bits shifted from the scan chain flip-flops. By repeating this process for a predetermined number of cycles, a very high indication of the faults in the circuit can be had.

Abstract: A motor control apparatus controls a motor speed according to a detected period of a frequency signal whose frequency is in proportion to the motor speed and drives the motor so as to keep its speed fixed according to a drive signal. The motor control apparatus includes a disturbance torque observer receptive to the drive signal and the detected period which produces a estimated disturbance signal corresponding to a conversion of a disturbance torque into an electrical signal. A comparator produces a period error signal which is a difference between the detected period and a desired period. An arithmetic unit produces the control signal in accordance with the period error signal. A torque correcting unit produces the drive signal by adding the estimated disturbance signal to the control signal.

Abstract: A liquid crystal panel used for a flat display can be produced at a high yield while scattering of hue and optical interference are vanished to realize a high quality display. 
     At each interface between adjacent layers (for example between a top substrate (1) and a color filter (8), or between a color filter (8) and an ITO film (4), or the like) the difference of the index of refraction is set to be 0.2 or less. 
     To that purpose an intermediate layer (12,13) may be inserted between two adiacent layers where the difference of the index of refraction is larger than 0.2. 
     Alternatively, if a layer has a difference of index of refraction larger than 0.2 with respect to an adjacent layer at either side thereof then its optical path "nd" is chosen to satisfy the relation 
 
       n d = N        λ       2               
 
 where λ denotes a design wavelength, and N a positive integer. 
Preferentially λ = 550 nm (green color wavelength). 
     Still alternatively, a minute rough surface of 0.01-0.5 µm may be formed at any interface where the difference of the index of refraction is larger than 0.2.

Abstract: Amine functional polymers which are terpolymers made up of randomly linked units of amidine or amidinium formate, N-vinylformamide and either vinylamine or vinylammonium formate are prepared by aqueous hydrolysis of poly(N-vinylformamide) at a temperature in the range of 90 to 175°C, preferably in the presence of a minor amount of ammonia or volatile amine. Best conversions and good control of polymer structure are obtained at 140 to 160°C with a small concentration of ammonia or alkylamine. Formation of poly(vinylammonium formate) containing no other salts or ionic coproducts is realized by degassing the hydrolyzate to remove ammonia or amine from the polymer solution. The poly(vinylammonium formate) affords distinct advantages in the production of salt-free polymers by catalytic decomposition of impurities. Poly(vinylamines) containing significant amounts of amidine functionality offer advantages in applications where increased basicity is required.

Abstract: Amine functional polymers are purified to remove formate present by contact with a supported Group VIII metal hydrogen transfer catalyst under conditions favoring formate decomposition to carbon dioxide and hydrogen which are removed as gases. The preferred catalyst is palladium on carbon. Essentially salt-free poly(vinylamines) can be obtained by hydrolysis of polymers of N-vinylformamide in aqueous solution using ammonia or a volatile amine as a hydrolysis agent so that formate salts are the principal by-product of the hydrolysis which creates amine functionality in the polymer. Formate can then by removed by the catalytic decomposition described. Removal of carbon dioxide is enhanced by degassing the hydrolyzate prior to formate decomposition and by nitrogen purge of the polymer solution during the catalytic decomposition reaction.
