Abstract: A vehicle steering system, including: a steering actuator including an electric motor, a steering rod configured to steer a wheel by a steering amount, and a motion converting mechanism configured to convert a rotating motion of a motor rotation shaft into a motion of the steering rod; first and second motor rotation angle sensors configured to detect a motor rotation angle; a steering amount sensor configured to detect a motion amount of the steering rod as the steering amount; and a controller configured to execute a steering amount control and to perform detection-value inappropriateness determination in which it is determined that any one or two of a detection value of the first motor rotation angle sensor, a detection value of the second motor rotation angle sensor, and a detection value of the steering amount sensor are inappropriate based on comparison among the detection values.

Abstract: A vehicle of a steer-by-wire type includes: a turning device that turns a wheel by actuating a turning motor; and a reaction torque generation device that applies a reaction torque to a steering wheel by actuating a reaction motor. A control device for the vehicle is configured to control turning of the wheel by controlling the turning motor and to control the reaction torque by controlling the reaction motor, according to rotation of the steering wheel. When a power output limiting condition is satisfied, the control device executes not only power output limiting processing that limits a power output of the turning motor but also reaction torque increasing processing. In the reaction torque increasing processing, the control device controls the reaction torque to make the steering wheel harder to rotate as compared with a case where the power output limiting processing is not executed.

Abstract: A plurality of magnetic pole bodies, provided on a stator of a steering motor, are divided into two electrically independent groups. Each group includes i) six magnetic pole bodies that are arranged in succession and ii) a corresponding number of magnetic pole bodies arranged opposing those six magnetic pole bodies. The two groups vibrate only slightly when operating normally. However, if one of the groups fails, vibration of the stator from elastic deformation in an undulating manner in the circumferential direction will increase, thereby alerting the driver of an abnormality in the steering motor. This increases the likelihood of measures being taken promptly to fix the abnormality in the steering motor, thus improving fail-safe performance.

Abstract: A steering apparatus for a vehicle is set to a steer-by-wire mode with an electromagnetic clutch being in a disconnected state. In response to steering operation applied to a steering wheel, first and second electric motors turn left and right front wheels. When a failure arises in one of first and second turning control systems including the first and second motors, the turning characteristic of the left and right front wheels is gradually changed from a turning characteristic for steer-by-wire to that for steer-by-mechanical connection. When a failure arises in the first and second turning control systems or after the turning characteristic is changed, the electromagnetic clutch is brought into a connected state, whereby the steering apparatus is switched to a steer-by-mechanical connection mode. Even when the steer-by-wire mode is switched to the steer-by-mechanical connection mode, a driver is not given an unnatural sensation, and excellent steering stability is maintained.

Abstract: One or a plurality of prime numbers pi which are generated and a generated random number are used to calculate a larger prime number candidate, and a judgment is made as to whether or not the prime number candidate is a prime number by using a provable prime number judging method, and when the judgment is made that the candidate is a prime number, the prime number p is outputted. As for at least three polynomials F(p) which are factors of ps−1 (s: arbitrary natural number) by a prime number p, a measure against prime factorization is taken. Moreover, when the prime number p is used for a secret key of RSA cryptosystem, a strong prime number p against the iterated-encryption attack on RSA cryptosystem is generated.

Abstract: N-(12-Nitroxydodecyl)-6-(4-ethyl or isopropyl-1-piperazinyl)pyridine-3-carboxamide or physiologically acceptable salts thereof. The said compounds have excellent inhibiting activity of cerebral edema, especially ischemic cerebral edema, and inhibiting activity of delayed neuronal death (an inhibiting activity of Ca-influx in neuronal cells). Cerebral edema is a pathologic condition accompanying cerebrovascular disorders, especially the acute stage cerebrovascular disorders and then the compounds are useful as an inhibiting agent for cerebral edema or a therapeutic agent for cerebrovascular disorders. Moreover, because the compounds do hardly show a behavior suppressing action, which is considered to be side effect in treating cerebrovascular disorders at the acute stage, they are an excellent therapeutic agent for, in particular, the acute stage cerebrovascular disorders.
