    • In the case where, e.g., because of provision of a high-gain and high-energy Q-switched laser oscillator in a laser system in a MOPA configuration, the duration τz from the time point when oscillation-stage Q switches (13a and 13b) start the gate ON to the time point when a pulse laser beam (18) starts to grow is shorter than the fall time τf of amplification-stage Q switches (13c, 13d, and 13e), by implementing control in such a way that the gate-ON timing of the oscillation-stage Q switches (13a and 13b) lag behind the gate-ON timing of the amplification-stage Q switches (13c, 13d, and 13e) by a predetermined time, the loss in the pulse laser beam (18) at the amplification-stage Q switches (13c, 13d, and 13e) can be prevented, while the gain deterioration due to a spontaneously amplified ray (17) produced in the amplification stage is being suppressed. Therefore, a high-energy pulse laser beam can efficiently be obtained.
    • 在例如由于在MOPA配置中在激光系统中提供高增益和高能Q开关激光振荡器的情况下,从振荡级Q开关的时间点(13a和13b)开始的持续时间τz )通过实施控制,使脉冲激光束(18)开始生长的时间点比通过放大级Q开关(13c,13d和13e)的下降时间τf短的时间点开启门,使得 振荡级Q开关(13a和13b)的栅极导通定时滞后于放大级Q开关(13c,13d和13e)的导通时间定时,脉冲激光器的损耗 可以防止在放大级Q开关(13c,13d和13e)处的光束(18),同时抑制由放大级中产生的自发放大的光线(17)引起的增益劣化。 因此,可以有效地获得高能脉冲激光束。

    • The voltage applied to a power converter is detected by a voltage detector, a function generator produces a voltage proportional to this detected voltage, and a high-pass filter detects an AC component superimposed on the voltage. An adder adds a bias voltage to this AC component, and an adder adds the output from the adder and the output from the function generator. The output from the adder is compared with a triangular wave produced from a rectangular wave generator, and a switching element is controlled to make switching operation according to the compared result. When a DC current is decreased by the AC component, a resistance current Ib is increased so that the AC components superimposed on the current and resistance current can be cancelled out.
    • 施加到功率转换器的电压由电压检测器检测,功能发生器产生与该检测电压成比例的电压,高通滤波器检测叠加在电压上的AC分量。 加法器向该AC分量加上偏置电压,加法器将来自加法器的输出和来自函数发生器的输出相加。 将来自加法器的输出与由矩形波发生器产生的三角波进行比较,并且根据比较结果控制开关元件进行开关操作。 当直流电流被交流分量降低时,电阻电流Ib增加,从而可以消除叠加在电流和电阻电流上的交流分量。

    • To determine the timing of the electrical brake for completely stopping in electrical braking control, and also to achieve both sure stopping and good riding comfort in an electric vehicle powered by the motor by decreasing the braking force at a prescribed rate of change, the torque of the electric motor is controlled by controlling the power converter which powers the motor using a power converter controller. The deceleration of the motor is computed based on the detected speed of the electric motor which is as an output of the speed detection means, the subsequent speed of the electric motor is estimated based on the detected speed and the deceleration rate of the electric motor at the time the detected rotational speed of the electric motor falls below a prescribed speed, and torque control is carried out using an electric power converter controller, based on the estimated speed.

    • An intracavity wavelength conversion laser apparatus has a stable resonator in which a solid-state laser active medium, a resonator Q-value modulating element, and a wavelength conversion crystal, a nonlinear element, are arranged along a laser optical axis for generating a Q pulse wavelength conversion laser beam. A mirror constituting the stable resonator, which is positioned close to the wavelength conversion crystal, is a convex mirror, whereby the Q pulse wavelength conversion laser beam has a short pulse width. The laser apparatus is easily operated with high efficiency and has a small size. The Q pulse wavelength conversion laser beam is generated with excellent reproducibility and stability, and the wavelength conversion crystal is less susceptible to optical damage.
