    摘要： A piezoelectric type ink recording device has piezoelectric elements for ejecting ink droplets. Variation can exist in characteristics of the piezoelectric elements that results in variation in speed at which the piezoelectric elements eject ink droplets. In order to suppress this variation in ejection speed, the ink recording device has a driver shared by all of the piezoelectric elements and a separate discharge control circuit for each piezoelectric element. The driver shared and the separate discharge control circuits output pulses to the piezoelectric elements in synchronization. Each piezoelectric element starts discharging its charge in synchronization with the falling edge of a drive pulse from the driver. As a result, the piezoelectric elements deform during the falling edge of the drive pulse to increase volume of corresponding ink chambers, thereby drawing ink into the ink chambers. However, each piezoelectric element continues discharging for a time determined by the width of the pulse from the corresponding discharge control circuit. In this way, the amount of charge discharged from each piezoelectric element can be individually regulated by changing the pulse waveform applied to each piezoelectric element by the corresponding discharge control circuit.

    摘要翻译： 压电型油墨记录装置具有用于喷射墨滴的压电元件。 在压电元件的特性中可能存在变化，导致压电元件喷射墨滴的速度变化。 为了抑制喷墨速度的变化，墨水记录装置具有由所有压电元件共享的驱动器和用于每个压电元件的单独的放电控制电路。 驱动器共享，并且单独的放电控制电路同步地向压电元件输出脉冲。 每个压电元件与驱动器的驱动脉冲的下降沿同步开始放电。 结果，压电元件在驱动脉冲的下降沿期间变形，从而增加相应的墨水室的体积，从而将墨水吸入墨水室。 然而，每个压电元件继续放电一个由相应的放电控制电路的脉冲宽度确定的时间。 以这种方式，可以通过改变由相应的放电控制电路施加到每个压电元件的脉冲波形来分别调节从每个压电元件放电的电荷量。

    摘要： A polygon mirror mounting structure mounting a polygon mirror to an outer periphery of a rotor includes a mirror seating surface formed on the outer peripheral portion of the rotor for seating the polygon mirror thereon, and a retaining member having a ring-shaped configuration and a plurality of radially extending pawls on the outer periphery thereof for retaining the polygon mirror on the mirror seating surface. The pawls have an arcuate or tapered cross-sectional configuration and directly press the polygon mirror downwardly and radially outwardly, to thereby enable securing the polygon mirror to the rotor without providing through-holes for receiving screws in the polygon mirror.

    摘要： Light from a mercury lamp is focused by an objective lens system and is incident on a specimen to be examined. A focusing optical path of light reflected by the specimen is split into an optical path of an ultraviolet ray and an optical path of visible light by a dichroic mirror having wavelength selectivity. The ultraviolet ray is guided to an ultraviolet CCD camera. The ultraviolet CCD camera supplies a monochrome picture signal to a monochrome display through a first picture processor. On the other hand, the visible light is guided to a color CCD camera. The color CCD camera supplies a color picture signal to a color display through a second picture processor. Therefore, an ultraviolet picture of the specimen is displayed on the monochrome display at a high resolving power and a large magnification. At the same time, a color picture of the specimen is displayed on the color display.

    摘要： The invention provides an improvement in the partial nuclear hydrogenation of an aromatic hydrocarbon compound in the liquid phase with admixture of water catalyzed by a ruthenium-containing solid catalyst. The scope of the invention is in the use of a novel ruthenium-containing catalyst supported on a silica gel and the like carrier and the catalyst is prepared by the hydrolysis and gelation of an alkoxide of silicon or aluminum in a solution containing a ruthenium compound, e.g. ruthenium alkoxide, followed by drying of the gelled material so that the resultant catalyst is very uniformly impregnated with the ruthenium ingredient to be imparted with greatly improved catalytis activity and selectivity for the intended reaction over conventional ruthenium-containing catalysts prepared by post-impregnation of a preformed silica gel carrier.
