    摘要: The invention is concerned with the miniaturization of construction of solid state imaging devices used in electric cameras, endoscopes or the like. A flexible printed circuit board assembled with some peripheral components thereon is attached to a side surface of a solid state imaging element to expose the element directly to incident light. The element is composed of a CCD chip and a light transparent cover sized about same as the CCD chip, and both are electrically connected using conduction bumps.

    摘要: A driving circuit controls a time for applying a drive signal to a piezoelectric element so as to bring a control in the number of ink droplets squirted from a liquid surface of liquid ink according to a gray scale level of an image to be printed on a printed object. According to application of the drive signal, acoustic waves emitted from a piezoelectric element array are focused in a main scanning direction, made incident to an acoustic lens via an acoustic matching layer, further focused in a direction orthogonal to the main scanning direction and focused in a vicinity of the liquid surface in a point form. In the vicinity of the liquid surface, an ink liquid mound is formed by means of pressure (discharging pressure) generated by the focused acoustic waves and then from a tip of the ink liquid mound an ink droplet according to the application time is squirted. The squirted ink droplet is ejected and stuck to the printed object. By performing main and subscanning to the printed object, a two-dimensional image is printed thereon.

    摘要: In an automatic focus control apparatus for a video camera including an image pick-up element for picking up an optical image obtained through a lens system composed of a focus lens group, a zoom lens group, a focal position correction lens group and a relay lens group and a defocus detector for detecting a defocus signal corresponding to a defocus of the lens system from an image signal output from the image pickup element, a piezoelectric actuator is provided to move the image pick-up element in an optical-axis direction in accordance with the defocus signal and a motion transmission mechanism connects the image pick-up element to the relay lens group of the lens system to allow that lens group to be moved in a direction opposite to that in which the image pick-up element is moved. A stroke burden which is borne by the piezoelectric actuator can be alleviated by moving the relay lens group together with the image pick-up element.
