    • A digital/analogue converter for converting an input n-bit digital code, where n is an integer greater than one, has an n-bit digital input and an output for connection to a load, and includes: an array of (n−1) switched capacitors; and a switching arrangement. In one example embodiment, the switching arrangement is adapted, in a zeroing phase of operation, to connect a first reference voltage to the first plate of at least one capacitor of the array and to connect a second plate of the at least one capacitor to a voltage that, for at least one value of the input digital code, is different from the first reference voltage and is further adapted, in a decoding phase of operation, to enable, dependent on the value of the input digital code, injection of charge into the at least one capacitor. In one example embodiment, the converter may be a bufferless converter having an output for direct connection to a capacitive load.

    • A signal line driving circuit includes a shift register having a plurality of shift circuits, each of which shifts a start pulse successively to the next stage, synchronizing with the timing of a clock signal. In this signal line driving circuit, shift pulses are outputted from an AND gate based on output pulses of two adjacent shift circuits. Meanwhile, a width specifying pulse for specifying a pulse width of the shift pulse is inputted via a transistor whose ON/OFF operation is controlled by the shift pulse. A logical operation circuit operates an AND of the shift pulse and the width specifying pulse and outputs the result of operation to a signal line. When the shift pulse is non-active, the transistor becomes OFF, which causes the signal line transmitting the width specifying pulse to be disconnected from the signal line driving circuit, thereby reducing a capacitive load of wiring. As a result, reduction of a parasitic capacitance of the wiring, reduction in the number of elements, reduction in the size of an amplitude of an input signal, etc. in the signal line driving circuit are attained.
    • 信号线驱动电路包括具有多个移位电路的移位寄存器,每个移位电路将开始脉冲连续地移位到下一级,与时钟信号的定时同步。 在该信号线驱动电路中,基于两个相邻移位电路的输出脉冲,从与门输出移位脉冲。 同时,用于指定移位脉冲的脉冲宽度的宽度指定脉冲通过由移位脉冲控制其ON / OFF操作的晶体管输入。 逻辑运算电路对移位脉冲和宽度指定脉冲进行AND运算,并将运算结果输出到信号线。 当移位脉冲不起作用时,晶体管变为截止,使得将信号线发送宽度指定脉冲与信号线驱动电路断开,从而降低布线的容性负载。 结果,实现了信号线驱动电路中布线的寄生电容的减小,元件数目的减少,输入信号的幅度的减小等。

    • A position measuring laser apparatus includes first and second laser transmitter-receivers and a position measure. The laser transmitter-receiver includes a laser beam emitter for emitting a laser beam, and a laser beam receiver for receiving a laser beam resulting from the emitted laser beam reflected from a reference reflecting mirror. An optical axis of the laser transmitter-receiver is oriented at a required angle toward a moving body. The position of the moving body with respect to the reference reflecting mirror is measured based on a beam receiving signal of the laser beam obtained by the laser transmitter-receiver. The position measure compares a drive signal for driving the laser beam emitter with a beam receiving signal generated by the laser beam receiver to measure the position of the moving body based on the beam receiving signal when the drive signal and the beam receiving signal coincide with each other.
