摘要： A rotation control device capable of suppressing vibrations of a rotation unit produced due to changes in weight unbalances of the rotation unit. On a disc rotation control device 2, made up of a driving shaft 8 rotated along with an optical disc 90, a turntable 9, a motor rotor 10 and a magnet 15 mounted on the motor rotor 10, balancer members 6, 7 are mounted so that the balancer members 6, 7 are rotatably supported on the driving shaft 8. The disc rotation control device 2 causes rotation of the rotation unit such that a synthesized center of gravity of the rotation unit offset from the center of rotation by the unbalances of the optical disc 90 and the balancer members 6, 7 will coincide with the center of rotation.

摘要： A magnet is provided which holds spherical balancers in the central portion of a rotor when the rotation of the rotor is stopped. When rotations of the rotor is started, a larger torque T.sub.0 is transmitted from the rotor to the balancers. Thus, the balancers quickly start rotating. When the rotor rotates at high speed, the centrifugal force separates the balancers from the magnet and moves the same to the outer wall portion of the rotor. At this time, a torque T.sub.0 which is transmitted from the rotor to the balancer is reduced so that the balancers are moved in the circumferential direction. Thus, the automatic aligning operation is performed. The number (n) of the balancers is made to be a value obtained by the following equation:n=180/.theta.+0.5 (all digits to the right of the decimal point are discarded)wherein .theta.: angle of balancer balls disposed in the outer portion, in which .theta.=2sin.sup.-1 {r/(R-r)}R: radius of movable spacer: radius of each balancer ball

摘要： The amount of aldehyde emitted from a polyurethane and molded articles made of a polyurethane is reduced. The reduction of aldehyde emissions from polyurethanes is achieved by including a hydrazine compound as an aldehyde-scavenger in the polyol component of the polyurethane-forming reaction mixture. The hydrazine compound is used in an amount of 0.05 to 3.0 parts by weight, based on 100 parts by weight of the polyol mixture. Aldehyde emissions from molded polyurethane articles are reduced by including a hydrazine compound in the mold coating material in an amount of from 0.1 g/m2 to 10 g/m2.

摘要： The present invention provides a method for producing a polyurethane foam molded article from a polyisocyanate compound, a polyol mixture containing polyol, a catalyst and a crosslinking agent, and a blowing agent, said method comprising continuously injecting the polyisocyanate compound, the polyol mixture and the blowing agent into a mold, using a molding machine capable of separately supplying the polyisocyanate compound, the polyol mixture and the blowing agent, while the timing of starting to inject the blowing agent is delayed after the start of injecting the polyisocyanate compound and the polyol mixture. The inventive method produces, in a single stage, a polyurethane foam molded article having the skin or high density portion selectively formed on portions of the molded article actually requiring them, where the proportions of the skin and the high density portion and the foamed core can be varied freely.
