摘要： A purification process for polyhydroxycarboxylic acids which comprises dissolving polyhydroxycarboxylic acid in an water-immiscible phenol or an organic solvent containing said water-immiscible phenol, successively bringing the resulting solution into contact with water which contains an acidic material, separating the organic layer from an aqueous layer, and isolating polyhydroxycarboxylic acid from the organic layer. The process can efficiently remove a catalyst contained in the polyhydroxycarboxylic acid prepared in the presence of the catalyst, does not require polyhydroxycarboxylic acid to be in the form of a solid, and can treat polyhydroxycarboxylic acid in a higher concentration as compared with using chlorinated hydrocarbon as a solvent.

摘要： A worm gear mechanism includes a worm, a torque-transmitting worm wheel meshing with the worm, and an auxiliary worm wheel disposed concentrically with the torque-transmitting worm wheel. The auxiliary worm wheel has a pitch circle diameter set to be greater than a pitch circle diameter of the torque-transmitting worm wheel and hence meshes with the worm in a meshing phase different from that of the torque-transmitting worm wheel. A screw thread provided on the worm actually meshes with teeth of the torque-transmitting worm wheel along a length defined as an actual meshing length. The screw thread has an effective length reduced to be approximately equal to the actual meshing length.

摘要： An electric power steering apparatus comprising a rack shaft having two racks, a first rack-and-pinion mechanism for transferring a steering torque to the rack shaft, and a second rack-and-pinion mechanism for transferring an assist torque to the rack shaft. The second rack-and-pinion mechanism includes a pinion and a rack both being helical gears so that a large torque can be transmitted to the rack shaft. Teeth of the pinion and rack are arc profiled. The arc profiled teeth mesh with each other through a large contact area of concave and convex surfaces thereof and hence with a reduced contact pressure compared to involute profiled teeth. The arc profiled teeth thus have increased surface fatigue strength, bending strength and bending fatigue strength and can transmit an assist torque sufficiently to the rack shaft. Moreover, they have durability sufficient to withstand a torque load of a motor inertia.

摘要： An electric damper which does not transmit unbalance wheel vibration to a vehicle body is provided. A low-pass cutoff frequency setting unit and a high-pass cutoff frequency setting unit respectively set the cutoff frequencies for band-stop filters to a frequency band corresponding to unbalance wheel vibration based on a signal indicating a vehicle speed from a vehicle speed sensor, and a function as a band-stop filter comprising a low-pass filter computation unit, a high-pass filter computation unit and an adder is computed for a displacement rate of the vertical motion of a wheel calculated by a differentiating unit in a damper control unit. A damper control amount computation unit calculates a control amount of controlling an electric motor for a motor-driven damper based on the calculated filtered displacement rate, and outputs a control signal to a motor driving unit through a driving circuit output unit.
