Abstract: This invention relates to a method for electric field orientation of liquid crystal polymers and oriented materials of liquid crystal polymers obtained by the method. This electric field orientation method comprises applying a pulsating electric field which is predominantly unidirectional and whose magnitude is varying periodically or non-periodically to a liquid crystal polymer capable of forming an optically aniso­tropic melt phase. The oriented material of liquid crystal polymer thus obtained has been unidirectionally oriented and polarized. This oriented, polarized material of liquid crystal polymer can be utilized as a piezoelectric material, pyroelectric material, electret material, non-linear optical element or the like.

Abstract: A method of producing a continuous seam weld between two mating surfaces of a can includes the steps of supplying a bolus of laser energy at alternate spaced locations (1, 2 etc.) along the line of the mating surfaces to effect local melting of the mating surfaces. The bolus of energy is then allowed to dissipate initially by way of an enlargement in the size of the melt pool and subsequently by cooling to a level at which the pool solidifies. A further bolus of laser energy is supplied at intervening spaced locations (3) along the line of the mating surfaces to effect local melting of the mating surfaces. This bolus of energy is allowed to dissipate initially by way of an increase in the size of the melt pool and subsequently by cooling. The spacing between the alternate and intervening locations (1, 2, 3) and the power of the bolus of energy being of such magnitude that the size of each pool produced at each intervening location (3) during its enlargement overlaps a solidified pool (1, 2).

Abstract: This invention discloses a process for selectively hydrogenating doublel bonds in unsaturated polymers, such as polybutadiene. The utilization of the process of this invention results in a rate of vinyl hydrogenation which is slowed relative to the rate of backbone hydrogenation. By utilizing the process of this invention, the rate of hydrogenation of double bonds in the polymers is satisfactory. The process of the subject invention more specifically comprises contacting a polymer containing double bonds in its backbone and vinyl unsaturation with hydrogen in the presence of a polymer containing pendant groups having the structural formula -Rh(Pφ₃)₂X wherein φ represents a phenyl group and wherein X represents a halogen atom. Polymers having pendant -Pφ₂-Rh(Pφ₃)₂X groups are highly preferred catalysts for utilization in the selective hydrogenations of this invention.

Abstract: A composite digital signal received by a recording and reproducing apparatus includes a digital information signal and a control signal. The control signal represents a number of digital copy generation of the associated information signal. The information signal of the received digital composite signal is recorded into recording medium (9). The information signal is reproduced from the recording medium (9). During the reproduction of the information signal, a new control signal is generated which represents a number equal to one plus the number represented by the control signal of the received composite digital signal. The new control signal and the reproduced information signal are combined into a new composite digital signal. The new composite digital signal is outputted. A check is made as to whether or not the number represented by the control signal of the received composite digital signal is equal to a predetermined number. When the number represented by the control signal of the received composite digital signal is equal to the predetermined number, the recording of the information signal of the received composite digital signal is inhibited.
