Abstract: In an abrasive body used for polishing by a CMP method, provided with a resin structure, a plurality of abrasive grains, and a plurality of longitudinal pores, and made in a form of disc, the longitudinal pore has a length in a thickness direction of the abrasive body longer than a length in a planar direction of the abrasive body, the resin structure includes communicating pores each of which communicating with the longitudinal pore and/or communicating with other communicating pore, the communicating pores include at least one of the abrasive grains in the pores respectively, and the average diameter of the communicating pores is not more than 18 times larger than the average diameter of the abrasive grains.

Abstract: To prevent a driver from feeling uncomfortable when the driver touches a steering member in a state where a driving source is stopped, a vehicle steering system (1) is provided in a vehicle (2) that travels by a driving force generated by a driving source (51). The vehicle steering system (1) includes; a steering member (10) configured to accept a steering operation; and a reaction force actuator (13) configured to apply a reaction force to the steering member (10) in response to the steering operation. In a state where the driving source (51) is stopped, the reaction force actuator (13) is configured to apply the reaction force to the steering member (10) based on a stopped time position that is a position of the steering member (10) at a time when the driving source (51) is stopped.

Abstract: A steer-by-wire steering system for a motor vehicle or a steering system for an autonomous driving motor vehicle includes a controller configured or programmed to control steering of steerable road wheels depending on a driver's input or an input of an autonomous driving unit and to include a normal mode of operation with full steering functionality and no quality problems, and at least two degraded modes with degraded operation of the steering system. The steering system includes an evaluator to evaluate a state of performance degradation of the steering system and to set the operation mode of the controller based on an evaluation result from the evaluator.

Abstract: There is provided a honeycomb structure 100 comprising partition walls 1 separating and forming a plurality of cells 2 functioning as fluid passages. The partition walls 1 are made of cordierite, and, when an average pore size of the partition walls 1 is x (?m) while a porosity of the partition walls 1 is y (%), a relation of x and y is y??8.33x+86.66 and satisfies 0.5?x?5 and 35?y?70. The honeycomb structure 100 can improve thermal shock resistance without sacrificing any of light-off performance, catalyst coatability, and strength.

Abstract: The present invention is to provide a moisture-permeable material for wigs superior in moisture permeability, helping to suppress sweatiness when worn, and allowing easy attachment. A moisture-permeable material for wigs formed in a three-layer structure, including: a core material made of a porous polyurethane; a net layer provided on a side of the core material to be brought into contact with a head and formed of synthetic fibers or natural fibers; and a fiber layer which is laminated on the other side of the core material, which is formed of the synthetic fibers or the natural fibers, and in which artificial hairs or natural hairs are to be planted.
