  • Publication number: 20160054473
    Abstract: The optical sheet according to the present invention includes a first layer containing a polycarbonate resin and a second layer containing an amorphous polyamide resin, the first layer and the second layer being layered by coextrusion molding. The first layer and the second layer are peelable from each other; and a surface of at least one of the first layer and the second layer has a fine uneven shape formed thereat. Such an optical sheet including a plurality of layers can make the entirety sheet thick at the time of melt extrusion molding, and therefore the layered body during the molding can hold a sufficient amount of heat. This improves the transferability of the fine uneven structure. In addition, the layers may be peeled off so that one of the layers is used. In this case, the optical sheet can be made thinner.

  • Publication number: 20160033002
    Abstract: A damper apparatus according to an embodiment includes a pair of first plates, a second plate, an elastic member, a first friction material and a second friction material. The elastic member is configured to elastically deform in a circumferential direction of a rotation axis by a relative rotation between the pair of first plates and the second plate around the rotation axis. The first friction material is configured to generate a first friction torque in a case where the second plate rotates relative to the pair of first plates in a first direction from an initial state. The second friction material is configured to generate a second friction torque greater than the first friction torque in a case where the second plate rotates relative to the pair of first plates in a second direction which is opposite from the first direction from the initial state.

  • Publication number: 20150321659
    Abstract: The control device of the present invention is applied to a vehicle in which a second motor-generator is linked to an output gear train via a gear. This control device sets a lower limit value for the torque outputted by the second motor-generator when a first motor-generator is locked by a motor locking mechanism and a power split mechanism is put into a non-differential state, and controls the second motor-generator so that, when the power split mechanism is in the non-differential state, the magnitude of the torque outputted by the second motor-generator is at least equal to the magnitude of that lower limit value.

  • Patent number: 9103404
    Abstract: Providing a vehicle damper device enabling acquisition of hysteresis torque with a simple structure. When the stoppers 96 and 97 are actuated and the relative rotation is regulated between the plates 90, 92 and the disc plate 56, a slip occurs between the plates 90, 92 and the hub member 58. As a result, a friction force is generated between the plates 90, 92 and the hub member 58, and a hysteresis torque is generated based on this friction force. Since this configuration can be achieved by simply providing the plates 90, 92, the clip 94, and the stoppers 96, 97, the hysteresis torque can be acquired with a simple configuration without a significant design change.

  • Publication number: 20150184718
    Abstract: In a positive torsion angle region in which a torque is transmitted from an engine side, a small hysteresis torque is generated at all times. Therefore, torsional vibrations of a small amplitude occurring during idle operation can be effectively attenuated by the small hysteresis torque, without switching to a large hysteresis torque, for example, during idle operation of the engine. As a result, the driver can be prevented from feeling uncomfortable due to switching to a large hysteresis torque during idle operation, and drivability can therefore be improved.
