    • In a color image copying apparatus, a light-path change-over reflector is movable into and out of a light path extending from a light source to an exposing station where a color latent image is to be formed on a photosensitive recording medium according to color image information of an original image. When the change-over reflector is disposed in the light path, the light from the light source is oriented or shifted so as to display the color image information of the original on a monitoring screen. Filters are used for color correction. When monitoring the original image on the screen, the filters are moved away from the light path. Further, the filters can be superposed together for minute color control with respect to the photosensitive sheet.

    • To provide a piezoelectric actuator whereby impact resistance can be greatly improved without complicating the design or causing a reduction in drive efficiency.When a piezoelectric actuator 31 is incorporated into a main plate 14, an arm part 513 of a vibrator 50 is disposed across from a protrusion 144 via spaces SP1, SP2 having specific dimensions. With the presence of these spaces SP1, SP2, a free end FR moves freely within the spaces SP1, SP2 during driving, but a vibrating part 511 is captured at the free end FR by the protrusion 144 when external impact is applied, and the vibrating part 511 can therefore be prevented from moving beyond the dimensions of the spaces. Resistance against impact from falling can thereby be easily and greatly improved without reducing the drive efficiency, and the usual difficulty of reconciling both drive efficiency and impact resistance can be resolved.

    • To provide a drive detection means for a piezoelectric actuator that can detect an amount driven without requiring adding an encoder or other component while also preventing increasing the load. A rotor is disposed eccentrically to the axis of rotation to change the pressure applied from the rotor to a contact part as the rotor is driven. When the pressure changes, the amplitude of the detection signal output from the detection electrode 18 of the piezoelectric element changes in conjunction with rotor rotation, and how much the rotor has been driven can be detected by detecting the amplitude change. Size and thickness can therefore be reduced because providing an encoder, switch, or other component is unnecessary, and current consumption can also be reduced.
    • 提供一种用于压电致动器的驱动检测装置,该驱动器检测装置可以在不需要增加编码器或其它部件的同时也能够检测驱动量,同时也防止增加负载。 当转子被驱动时,转子偏心地设置在旋转轴上,以将从转子施加的压力改变为接触部分。 当压力变化时,从压电元件的检测电极18输出的检测信号的振幅与转子旋转一起变化,并且可以通过检测振幅变化来检测转子多少。 因此,由于不需要提供编码器,开关或其他部件,因此可以减小尺寸和厚度,并且还可以减少电流消耗。

    • A PLL frequency synthesizer is provided with a linearization circuit 6 which receives an oscillation frequency control signal VT from a loop filter LF. The linearization circuit 6 outputs a charge pump current control signal CPCONT, depending on a potential level of the oscillation frequency control signal VT. The larger the value of the charge pump current control signal CPCONT, the higher the potential level. A charge pump CP receives the charge pump current control signal CPCONT, and causes a current corresponding to the value to flow in or out. Therefore, with a simple circuit structure, loop gain characteristics of the PLL frequency synthesizer can be regulated to be constant. Therefore, even when a variable capacitance element incorporated in a voltage control oscillator has nonlinear characteristics with respect to the potential of the input oscillation frequency control signal, the loop gain characteristics of the PLL frequency synthesizer having the voltage control oscillator can be regulated to be constant.
    • PLL频率合成器具有从环路滤波器LF接收振荡频率控制信号V SUB的线性化电路6。 线性化电路6根据振荡频率控制信号V SUBT的电位电平输出电荷泵电流控制信号CP CONT 。 电荷泵电流控制信号CP 的值越大,电位电平越高。 电荷泵CP接收电荷泵电流控制信号CP ,并使与该值对应的电流流入或流出。 因此,通过简单的电路结构,可以将PLL频率合成器的环路增益特性调节为恒定。 因此,即使在电压控制振荡器中结合的可变电容元件相对于输入振荡频率控制信号的电位具有非线性特性,也可以将具有电压控制振荡器的PLL频率合成器的环路增益特性调节为恒定 。

    • An electronic timepiece without system failure at the time of transfer from the power-saving mode to the display mode is provided. A power-saving control circuit 400 controls drive of a date dial displaying a date when updating a date display, which has been stopped in a power-saving mode, to a current date at the time of transfer from the power-saving mode to the display mode. The power-saving control circuit 400 outputs a date dial drive inhibiting signal, which prohibits drive of the date dial 75, to a date-updating control circuit 300, if a voltage VDD of a power source unit B is less than or equal to a low threshold voltage V1. It outputs a date dial deceleration driving signal, which drives a date dial 75 with a predetermined speed slower than a normal update speed when transferring to the display mode, to a date-updating control circuit 300, if a source voltage VDD is equal to or less than a high threshold voltage V2.
