  • Publication number: 20160178413
    Abstract: In an indicating-needle type meter device, when starting excitation of a stepping motor, a controller sets the phase of an excitation signal to a predetermined excitation start position and returns the phase of the excitation signal by a predetermined reversal angle such that an indicating-needle rotates in the backward direction, thereby positioning the indicating-needle at a stopper position. Subsequently, the controller advances the phase of the excitation signal by an origin return angle to rotate the indicating-needle in the forward direction to an origin position apart from the stopper position by a predetermined angle, thereby positioning the indicating-needle at the origin position. Here, the origin return angle is an angle obtained by adding a backlash angle, a predetermined positive pre-offset angle, and a positive placing error correction angle set based on a placing error of the indicating-needle with respect to the stopper.

  • Publication number: 20160126644
    Abstract: A terminal holding member has a tubular shape and includes an accommodation portion into which an electroconductive member is inserted. The terminal holding member elastically holds a mating terminal and the electroconductive member when the mating terminal is inserted into a gap that is formed between the terminal holding member and the electroconductive member inserted into the accommodation portion. The terminal holding member includes a bottom portion that supports a bottom surface of the electroconductive member inserted into the accommodation portion, a surface-contact portion that faces the bottom portion and that is capable of coming into surface-contact with a first surface of the mating terminal, and a spring portion that connects the bottom portion and the surface-contact portion to each other so that the terminal holding member has spring properties with which the surface-contact portion is urged toward the bottom portion.

  • Publication number: 20160081777
    Abstract: A zirconia sintered body is provided in which the strength between layers of powders is improved. A flexural strength of a test sample of the zirconia sintered body, measured pursuant to JISR1601, is not less than 1100 MPa. The test sample is formed by preparing a plurality of zirconia powders, each containing zirconia and a stabilizer that suppresses phase transition of zirconia, the zirconia powders differing in a composition, layering the zirconia powders to form a zirconia composition, and sintering the zirconia composition to form a zirconia sintered body. The flexural strength is measured such that a load point is positioned at a boundary of the zirconia powders, the boundary traversing the test sample of the sintered body along a direction of load application.

  • Publication number: 20160009318
    Abstract: A collision avoidance assistance device configured to perform driver steering assistance to avoid a collision between a vehicle and an obstacle, the device includes a steering control unit configured to perform the steering assistance in a case where it is determined that there is a possibility of the collision between the vehicle and the obstacle. During a period from commencement of the steering assistance to elapsing of a first time determined by response characteristics of a lateral acceleration of the vehicle, the steering control unit is configured to rotate a steering wheel of the vehicle in a collision avoidance direction by a control amount determined based on a steering holding force of the driver.

  • Publication number: 20150367701
    Abstract: A shock absorber system installed on a vehicle having four wheels in which a VSC control for giving a braking force to any of the wheels is to be executed to reduce an improper turning behavior of the vehicle due to an excessive side slip of any of the wheels, including: four hydraulic shock absorbers each configured to generate a damping force with respect to a relative movement of a corresponding sprung and unsprung portion and having a damping-force changer configured to change the damping force; and a controller configured to control the damping force by controlling the damping-force changer and configured such that, when the improper turning behavior of the vehicle occurs, the controller executes a reduction control in which the damping force to be generated by at least one of the four shock absorbers is controlled to reduce the improper turning behavior.
