    摘要： A rare earth magnet in which the amount used of a heavy rare earth element is more reduced while maintaining enhancement of the coercive force, and a producing method thereof are provided.
    The rare earth magnet of the present disclosure has a main phase (10) and a grain boundary phase (20). The main phase (10) has a composition represented by, in molar ratio, R 1 2 T 14 B (R 1 is a rare earth element, etc. and T is a predetermined transition element, etc.). The main phase (10) has a core part (12) and a shell part (14). Denoting the abundances of R 2 and Ce (R 2 is a predetermined heavy rare earth element) occupying 4f site of the shell part (14) as R 2 4f and Ce 4f , respectively, and denoting the abundances of R 2 and Ce occupying 4g site of the shell part (14) as R 2 4g and Ce 4g , respectively, the rare earth magnet satisfies 0.44≤R 2 4g /(R 2 4f +R 2 4g )≤0.70 and 0.04≤(Ce 4f +Ce 4g )/(R 2 4f +R 2 4g ). The rare earth magnet-producing method of the present disclosure uses a modifier containing at least R 2 and Ce.

    摘要： In a stratification operation, O 2 is injected from an oxygen injector 24 during valve opening of an intake valve 26. Therefore, the injected O 2 flows into a combustion chamber 14 immediately after the injection, and forms a layer having a constant spread in the combustion chamber 14 (A in Figure 5 ). Meanwhile, the working gas in the combustion chamber 14 forms such a layer as to cover the O 2 layer on a wall surface of the combustion chamber 14 in conjunction with formation of the O 2 layer (B in Figure 5 ). In other words, in the combustion chamber 14, an inner layer with a high O 2 concentration (A in Figure 5 ) and an outer layer with a high working gas concentration (B in Figure 5 ) are respectively formed.

    摘要： A vehicle autonomous driving system includes a travel plan generation unit configured to generate a travel plan and a control width of a target control value, a travel control unit configured to calculate an control value, and a behavior determination unit configured to determine whether or not a behavior change which is opposite to the first behavior change is performed. In a case where it is determined that the opposite behavior change is performed, the travel control unit is configured to calculate the control value such that a behavior change amount of the first behavior change is smaller and becomes to be in the restricted vehicle state corresponding to the state within the control width compared to the case where the current vehicle state is caused to follow the target vehicle state when it is determined that the opposite behavior change is not performed.

    摘要： An internal combustion engine includes an ECU, an A/F sensor being active at a first temperature lower than a PM combustion temperature and set in advance, and a heater to heat the A/F sensor to a second temperature equal to or higher than the PM combustion temperature and set in advance. The ECU detects PM based on a difference between an output value of the A/F sensor at the first temperature and an output value of the A/F sensor at the second temperature. The ECU may perform determining that a PM accumulation amount is smaller than a reference amount when the output value is higher than a threshold value, and that the PM accumulation amount is equal to or larger than the reference amount when the output value is a value equal to or smaller than the threshold value.
