  • Patent number: 11171385
    Abstract: A method of forming a separator for a lithium-ion battery includes arranging a polymer film in contact with a sacrificial layer to form a cutting stack. The method includes disposing the cutting stack between a first vitreous substrate and a second vitreous substrate. The method includes applying an infrared laser to the cutting stack through the first vitreous substrate to generate heat at the sacrificial layer. The method also includes transferring heat from the sacrificial layer to the polymer film to thereby cut out a portion of the polymer film and form the separator. A method of cutting a polymer film and a cutting system are also explained.

  • Patent number: 11161290
    Abstract: The present invention prevents internal cracks occurring when an impeller molded using a fiber reinforced resin is manufactured by injection molding. This method for manufacturing an impeller is provided with: an injection step of filling a cavity with a molten resin containing reinforced fibers, from a gate side into which the molten resin flows, toward an opposite-gate side opposite to the gate side; and a dwell step of applying required pressure to the filled molten resin. In the injection step and the dwell step, directional cooling is performed with a temperature gradient such that the temperature becomes lower from the gate side toward the opposite-gate side. According to this method for manufacturing the impeller, the opposite-gate side shrinks with a decrease in the temperature of the molten resin since the temperature of the opposite-gate side is lower.

  • Patent number: 11059329
    Abstract: A motorcycle tyre intended to be fitted to the rear wheel of a motorcycle. The motorcycle tyre has a tread pattern with a high void-to-rubber ratio that provides a suitable draining. The tread pattern has pairs of primary grooves to carry out the draining function of the tyre, and arranged substantially according to the stress lines of the tyres to reduce the probability of triggering uneven wear. Also included are secondary grooves having a reduced dimension, in terms of both extension and width, arranged between the primary grooves to increase the grip of the tyre to the ground. Orientation of the secondary grooves increases stabilizing features against drift forces acting on the tyre, particularly in low or very low friction conditions.
