  • Publication number: 20170276200
    Abstract: A friction material for a brake pad comprises a fibrous base material without a metal fiber, and comprises a binder and a friction modifier. The friction material comprises 0.3% to 2.0% by weight, relative to the entire friction material, of a non-crosslinkable polyolefin having a melting point higher than the melting temperature of the binder. The friction material can suppress increase in friction coefficient of a friction material during initial brake operation and reduce the occurrence of abnormal effects and squealing in low-temperature and high-humidity environments.

  • Publication number: 20170088078
    Abstract: A vehicle occupant protection device includes an airbag module, an actuator, and a controller. The airbag module includes an airbag and an inflator that allows the airbag to develop. The actuator attaches the airbag module to a vehicle, to cause a change in relative positional relation between the vehicle and the airbag module. The controller determines a collision mode of the vehicle, on a basis of one or more of input information used in prediction of the collision mode, input information upon a collision of the vehicle, and input information on an internal situation of the vehicle, and controls the relative positional relation between the vehicle and the airbag module. The airbag module allows the airbag to be developed in a state in which the change in the relative positional relation between the vehicle and the airbag module is caused by the actuator.

  • Publication number: 20170069107
    Abstract: There is provided with an image processing apparatus. A first image sensor outputs a first image. The first image sensor has a relatively small amount of image deterioration caused by a motion of an object. A second image sensor outputs a second image. The second image sensor has a relatively large amount of image deterioration caused by the motion of the object. An estimation unit analyzes the first image and generates position and orientation information of the image processing apparatus. A rendering unit renders a CG object on the second image such that the CG object is superimposed at a position determined based on the position and orientation information.
