Granted: 1992-12-15
Abstract: FLEXIBLE THERMOPLASTIC POUCHES HAVING EASY-OPEN TEAR STRIP MEANS AND APPARATUS FOR MAKING SAME     ABSTRACT     A flexible thermoplastic pouch having an easy-open tear strip means secured thereto is provided.  According to one embodiment of the present invention, a tear strip is secured to an imperforate sidewall of a flexible pouch along two sawtooth securement lines arranged generally in the shape of an ellipse. The point where the two securement lines converge is given a W-shape, which provides two points of high stress concentration. When the user grasps and pulls the tear strip means, the securement lines rupture precisely at these two points of stress concentration and continue along the sawtooth securement lines, thereby providing the pouch with a dispensing opening of predetermined size, shape, and location.  A sealing die apparatus for forming sawtooth, notched lines of securement between the tear strip means and the flexible pouch is also disclosed.

Abstract: A B S T R A C T "PROCESS FOR PRODUCING A SMOOTH POLYESTER YARN AND        POLYESTER YARN PRODUCED BY SAID PROCESS"          In a process for producing a smoothy, low-shrinkage polyester filament yarn, the starting point is high-speed spun POY. The polyester POY is cold-drawn and then subjected to a hot relaxation under an overfeed of 10 to 20% at 140 to 250°C in a dry medium or at 70 to 140°C in a wet medium and if desired intermingled.      The result is a yarn having an initial modulus of 200 to 800 cN/tex and a boil shrinkage of less than 3%. The yarn is suitable for use as a replacement material for cellulose acetate.

Title: Gain and phase correction in a dual branch receiver
Inventor: CHUNG KAH-SENG
IPC: H04B1/26
Filed: 1988-08-31
Granted: 1991-12-17
Abstract: ? PHN 12.236 Abstract "Gain and Phase Correction in a Dual Branch Receiver"     A dual branch receiver consists first and second branches (12, 14) respectively comprising first and third mixers (16, 20) and second and fourth mixers (17, 21). An input terminal (10) for a signal having a carrier frequency (.omega.c) is connected to the first and second paths. A first local oscillator frequency (.omega.o) is supplied in quadrature to the first and second mixers (16, 17), where.omega.c-.omega.o = .DELTA..omega. and .DELTA..omega.is of the order of 2.pi. x 100 radians/sec. A second local oscillator (30) frequency is supplied in quadrature to the third and fourth mixers (20, 21). An output signal is derived by connecting a sum circuit (22) and a difference circuit (24) to the first and second branches. The outputs of the sum and difference circuits (22, 24) are also used to provide gain and phase correction signals. It has been found that if the correction signals are based on signals centred on 2.DELTA..omega. then they are substantially free of ripple. The gain correction is derived by mixing the 2.DELTA..omega.signals derived by multiplying difference by difference (or sum by sum) with the 2.DELTA..omega.signals derived by multiplying sum by difference and low pass filtering. The phase correction is derived by mixing a 90° phase shifted difference signal with the sum signal (or vice versa) and deriving the 2.DELTA..omega.signals which are mixed with 2.DELTA..omega.signals derived by multiplying the difference by difference (or sum by sum) and low pass filtering.

Title: Method for controlling the front wheel steer angle
Inventor: FURUKAWA YOSHIMI
IPC: B62D7/08
Filed: 1988-09-26
Granted: 1993-04-13
Abstract: ABSTRACT OF THE DISCLOSURE      The method of the present invention improves the damping property of the yaw motion of the vehicle by feeding back a detected yaw rate value in a dynamic sense for compensating the front wheel steer angle so as to increase the damping coefficient of the yaw motion of the vehicle.  By controlling the front wheel steer angle by accounting for not only the proportional term of the steering wheel input angle but also the derivative term which is proportional to the steering wheel input angular speed, in the feed-forward control of the front wheel steer angle in relation with the steering operation by the driver, and by appropriately varying the control parameters of the yaw rate feed-back and the steering wheel input feed-forward, the yaw response of the vehicle can be made proportional to the steering wheel input, and the response delay in the yaw rate against the steering wheel input can be reduced to substantially zero.

Abstract: CURTAIN COATING METHOD AND APPARATUS               ABSTRACT Method and apparatus for applying one or a plurality of superimposed layers of a photographic coating composition by the curtain coating method onto a moving support.  The spacing between the edge guides, used to maintain the width of a curtain throughout its free fall from the coating hopper to the impingement line on the support, is arranged to coat less than the width of the support so as to provide an uncoated margin on the support.  The curtain fluids are extracted from the edge region of the falling curtain by connecting a suction device to the edge guides near the point of impingement of the falling curtain, thus substantially reducing the thickness of the curtain at its edge region and thereby reducing the thickness of the coated edges.
