    • A polyester film having fine voids, which comprises a polymer mixture comprising a polyester resin and a thermoplastic resin (B) incompatible with said polyester resin, and which has an apparent specific gravity of 0.6-1.3 and an inplane birefringence as determined from the equation: inplane birefringence=refractive index along lengthwise principal axis-refractive index along crosswise principal axis, of from -0.02 to +0.04, and manufacture thereof. A thermoplastic resin film having fine voids, which comprises a polymer mixture comprising a thermoplastic resin (A) and a thermoplastic resin (B) incompatible with said thermoplastic resin (A), and which has a ratio (L1/L2) of an average length (L1) of the voids at a cross section in the lengthwise direction of the film, to an average length (L2) of the voids at a cross section in the direction forming a right angle with said lengthwise direction, i.e., crosswise direction of the film, of 2/3-3/2, a thickness variation of the film of not more than 5%, and a void content of 5-50% by volume, and manufacture thereof. The polyester film having fine voids of the present invention has an extremely superior isotropy, excellent tear resistance, extremely superior water resistance, moisture absorption, dimensional stability, surface stability, gloss and vividness of printed matters, and mechanical strength, which have been particularly achieved by making apparent specific gravity and inplane birefringence fall within a specific range mentioned above. The thermoplastic resin film having fine voids of the present invention suffers less from curling by heat, which has been achieved by making (L1/L2), thickness variation and void content fall within a specific range mentioned above.

    • An electric power steering control device includes a motor controller for controlling an electric motor providing the assisting steering torque; and a clutch controller for controlling an electromagnetic clutch selectively connecting the assisting steering torque of the motor to the steering system. The degree of engagement (connection) of the clutch corresponds to the clutch current command level I.sub.C. When the vehicle speed is above a predetermined speed V.sub.0 (i.e., during high speed driving), the clutch current I.sub.C is set at a predetermined half current level I.sub.CR. During low vehicle speeds below V.sub.0, the clutch current I.sub.C is gradually decreased to the half current level I.sub.CR as the vehicle speed increases to V.sub.0. When the steering torque T is above a first predetermined level T1 indicative of an abnormality during high speed operation, the clutch current I.sub.C is set at a minimal level I.sub.CO. The steering torque T is returned to the half current level I.sub.CR when it is below a second predetermined level T2 smaller than the first level T1, thereby avoiding steering torque hunting.
    • 电动助力转向控制装置包括:电动机控制器,用于控制提供辅助转向转矩的电动机; 以及用于控制电磁离合器的离合器控制器,其选择性地将马达的辅助转向扭矩连接到转向系统。 离合器的接合度(连接)对应于离合器电流指令级IC。 当车速超过预定速度V0(即,在高速行驶期间)时,将离合器电流IC设定为预定的半电流水平ICR。 在低于V0的低车速下,当车速增加到V0时,离合器电流IC逐渐降低到半电流水平ICR。 当转向转矩T高于表示高速运转时的异常的第一规定电平T1时,将离合器电流IC设定为最低电平ICO。 当转向转矩T低于小于第一电平T1的第二预定电平T2时,转向转矩T返回到半电流电平ICR,从而避免了转向转矩的旋转。
