    • An oil pressure command value for slip-control of a lock-up clutch of a torque converter is calculated based on a feed-forward oil pressure value calculated by an FF value calculating unit and a feed-back oil pressure value calculated by a feedback value calculating unit. When the feedback oil pressure value is calculated, a deviation out-of-range determining unit determines whether a deviation between actual rotational speed difference and target rotational speed difference is outside of a predetermined range. If the deviation is outside of the predetermined range, a feedback value correcting unit calculates a correction value and corrects the feedback oil pressure value. Therefore, when the deviation is outside of the predetermined range, the actual rotational speed difference is brought into convergence with the target rotational speed difference with rapid response. When the deviation falls within the predetermined range, normal feedback control is adopted to assure stability without overshooting, even in a high engine speed, high engine torque state.
    • 基于由FF值计算单元计算的前馈油压值和由反馈值计算出的反馈油压值,计算用于变矩器的锁止离合器的滑差控制的油压指令值 计算单位。 当计算出反馈油压值时,偏差超出范围确定单元确定实际转速差和目标转速差之间的偏差是否在预定范围之外。 如果偏差超出预定范围,则反馈值校正单元计算校正值并校正反馈油压值。 因此,当偏差超出预定范围时,实际转速差与目标转速差快速响应。 当偏差落在预定范围内时,即使在高发动机转速,高发动机转矩状态下也采用正常反馈控制来确保稳定性而不会过冲。

    • While calibrating the position of a robot having a gyro, the robot emits a beam of light to a target wall surface, and the position of a laser point on the target wall surface illuminated by the beam of light is measured. The measured position is obtained as an initial value (S10, S12), and a start of calibration is indicated (S14, S16). Then, a calibration period is reset (S18) and the timekeeping process of the calibration period starts. The values detected by the gyro are consecutively obtained by sampling for a predetermined calibration period (S20). If a disturbance occurs while the values are obtained, an alarm is output and calibration restarts. Once the calibration period elapses without any disturbance, a calibrated value is set or determined based on the detected values obtained during the calibration period (S26, S28).

    • The present invention is to provide a semiconductor light-emitting device with a variable output wavelength that reduces the wavelength dependence of the optical output power. The light-emitting device provides an optical cavity defined by a reflective end and a reflector. The gain waveguide and the ring resonator are set within the cavity. The reflector comprises a plurality of gratings each accompanied with an electrode. The periodicity of the refractive index in respective gratings is different from each other. The ring resonator shows a plurality of transmission maxima. The light-emitting device emits light with a wavelength defined by the transmission maxima of the ring resonator and the enhanced reflectivity region adjusted by the bias applied to electrodes of the optical reflector.
