摘要： Provision of a power steering system which is capable of preventing a delay in response for outputting a solenoid current instruction value SI. A controller C stores a table of basic current instruction values I1 corresponding to combinations of steering angles and steering angular velocities. The controller C obtains a basic current instruction value I1 from the table, and multiplies the obtained basic current instruction value I1 by a current instruction value I2 determined on the basis of a vehicle speed, and then determines the multiplied value as a solenoid current instruction value SI.

Leaf spring structures each of which includes a first leaf spring and a second leaf spring are arranged. The first leaf spring includes a spring-side support section constituted by a V- or U-shaped groove, a pair of rolling surface sections arranged so as to be contiguous to the spring-side support section and outwardly extend from both ends of the spring-side support section, a pair of support leg sections each arranged so as to be contiguous to each of the rolling surface sections and outwardly extend therefrom, and a pair of holding sections each arranged so as to be contiguous to each of the support leg sections and outwardly extend therefrom. The holding sections each are pressedly contacted with press contact surfaces or side surfaces of a spring receiving chamber, resulting in the first leaf spring being securely held. The second leaf spring acts to exhibit elastic force required for forcing balls or rollers against an input shaft from a rear surface of the first leaf spring.

摘要： A light diffusive sheet of the present invention comprises a transparent polymer sheet provided with a light diffusion layer 3 on one side and an uneven surface 4a having arithmetical mean deviation of 0.5 μm or less and mean spacing of 80 μm or narrower on the opposite side. Such an uneven surface can be made by forming a backcoat layer 4 including a mixture of particles having particular mean diameters in a particular proportion to a binder resin on the transparent polymer sheet. An area light source element 7 of the present invention is produced by laminating a prism sheet 6 on a light guide plate 5 so that the prism surface 61 of the prism sheet 6 is opposed to the light-emitting surface 51 of the light guide plate 5 and laminating the light diffusive sheet on the prism sheet 6 so that the uneven surface (backcoat layer) of the light diffusive sheet is opposed to the surface opposite of the prism surface. The light diffusive sheet of the present invention can prevent occurrence of a rainbow-like annular pattern without deteriorating the front luminance and view angle of the area light source even when combined with a downward-facing prism sheet.

摘要： For an energy-saving type control, a value of a control low rate QP controlled by a flow control valve V is closer to a value of a flow rate required by an output side such as a power cylinder 8, a steering valve 9 or the like, to suppress a driving torque of a pump P. An excitation current I of a solenoid SOL is specified on the basis of a solenoid current instruction value IT based on a steering torque and a solenoid current instruction value IS defining a standby flow rate.

摘要： An object of the present invention is to provide a power steering apparatus in which its neutral rigidity can be raised by applying a preset force and which is superior in its assembly performance and productivity.To attain this object, first supporting portions are formed in a pair of spring members disposed across the input shaft, and second supporting portions are formed in the input shaft so as to oppose the first supporting portions. When the input shaft and the output shaft are rotated relative to each other so that the balls or rollers are about to slip out of the first and second supporting portions, the balls or rollers roll and move while deflecting the spring members.
