    Abstract: An actuator for a contactor comprises an electromagnet having a closing coil, a holding coil, fixed cores wound with the closing coil and the holding coil respectively, a movable core provided on one side of the fixed cores, and a yoke. A main contact movable member operates to perform closing or interrupting by attraction or release of the movable core with respect to the fixed core. The actuator has a trip spring, energy-stored during the closing, that performs the interrupting upon stopping energization to the holding coil and thereby releasing the stored-energy. The actuator has an auxiliary contact operating with the operation of the movable core and performing energization switching with respect to the closing coil and the holding coil. The trip spring is provided on one side of the electromagnet in a horizontal direction while the auxiliary contact is provided on the other side.

    Abstract: Method, system and device for assisting diagnosis of autism which enable assistance of early detection and early definite diagnosis of autism (especially in infants) based on objective evaluation, using a conventionally suggested “eye-gaze detection technique”. The method for assisting diagnosis of autism of a subject uses an eye-gaze detecting unit, the unit having at least an imaging camera portion. The method includes displaying, at the position in front of the subject along the direction of the eye gaze of the subject, an illusionary image contained in a plane of an illusion-causing image on a displaying device. The eye-gaze position information of the subject looking at the plane is detected, and the eye-gaze position information of the subject is input into an eye-gaze position information storage portion The eye-gaze positions of the subject can be evaluated using a algorithm for assisting diagnosis of autism.

  • Patent number: 8664960
    Abstract: When a battery current is not larger than a limit current set depending on the battery temperature and is flowing continuously for a predetermined time set depending on the battery temperature or longer, a decision is made that a secondary battery is in stable state. When the secondary battery is in stabilized state, the battery voltage is considered to be equal to the open circuit voltage and SOC estimation is performed based on the open circuit voltage-SOC characteristics. When the product of the internal resistance of the secondary battery and the limit current is made substantially constant (constant voltage) by setting the limit current in association with temperature dependence of the internal resistance, estimation error can be kept within a predetermined range in the stabilized state even if SOC estimation is performed while the battery voltage is assumed as the open circuit voltage.
