Abstract: The present invention provides a method for producing a differently shaped polarizing plate, the method being capable of preventing a decrease in durability. The method for producing a differently shaped polarizing plate of the present invention includes a step of forming a differently shaped portion by moving at least one of a rectangular polarizing plate and an end mill blade while the end mill blade is rotated and pressed against the rectangular polarizing plate to cut the rectangular polarizing plate. Preferably, the step is performed while a jig is pressed against the rectangular polarizing plate, at the periphery of a region to be cut.

Abstract: Steering of a vehicle is assisted by a motor driven according to a steering signal formulated by a digital computer. The steering signal is formulated so that a high and quick power-assist is obtained when the steering is steep or sharp, while trembling vibrations appearing on a steering wheel due to noise are suppressed when the steering is slow or the steering wheel is stably held. A steering velocity calculated from a steering angle and a steering torque signal detected from a torsional torque of a steering shaft are used to formulate the steering signal. An original steering torque signal is modified by a transfer function having a higher gain and a higher phase advance in a certain frequency range thereof, thereby formulating a final steering signal which controls operation of the power-assist motor.
