    摘要： A focusing apparatus for video camera or the like in which a change-over between automatic focusing and manual focusing is possible comprises an endlessly rotatable and hand-worked manipulator, a detector for detecting the direction and amount of manipulation or rotational movement of the manipulator, and a controller/driver for moving a part of optical elements in an optical system along its optical axis direction in a direction corresponding to the direction of manipulation of the manipulator detected by the detector and by a distance corresponding to the amount of manipulation of the manipulator detected by the detector, thereby taking the focus.

    摘要： A video camera has a memory for storing the position of an image lens in relation to the position of a variator lens, that is, zoom tracing curves in respect of individual subject distances, a motor for moving the image lens while vibrating it slightly during zooming operation, a variation component extractor circuit for extracting the amplitude and phase of a slight variation component of focusing voltage generated by moving the image lens while vibrating it slightly, and a controller for controlling drive means on the basis of the stored zoom tracing curves and an extracted slight variation component. During zooming operation, the controller first controls the motor in compliance with a position of the variator lens pursuant to a zoom tracing curve stored in the memory in association with a position assumed by the image lens immediately before start of the zooming operation. The controller also operates to correct a drive amount of the image lens on the basis of amplitude of an extracted slight variation component and when the amplitude of the slight variation component falls below a predetermined value, the controller controls the motor pursuant to a newly determined zoom tracing curve.

    摘要： An electronically-controlled focusing adjustment apparatus including manual focusing adjustment means using a manual focusing adjsutment device such as a variable resistor, focusing lens position detection means, and feedback means for comparing a voltage outputted from a movable terminal of the manual focusing adjustment device with a voltage outputted from the focusing lens position detection means and for feeding back the error between the two voltages to a motor for driving the focusing lens. Desired manual focusing is thus attained with respect to an object located at an arbitrary distance.

    摘要： An automatic focusing apparatus for a video camera converts the quantity of reflected light reflected by an object into an electric signals by light receiving elements. The electric signals are detected and the detected signals are integrated by integrators once every fixed period. A decision is made on the basis of the respective outputs of the integrators whether or not the video camea is in focus. The detectors and the integrators have offset voltages, respectively. The outputs of the integrators are sampled and held and are compared with a reference voltage equal to a voltage for resetting the integrators. Signals representing the result of the comparison are fed back to the detectors or to the integrators to regulate the offset voltages of the detectors and the integrators.

    摘要： The present invention provides a production process by which a water-absorbent resin of excellent quality can be obtained at a low cost by reasonable steps in aqueous solution polymerization. The process for producing a water-absorbent resin comprises the step of polymerizing an aqueous solution of water-absorbent resin-forming monomers including acrylic acid and/or its sodium salt as major components, wherein: (1) the aqueous solution has a monomer component concentration of not less than 45 weight %; (2) the polymerization is carried out while water is evaporated so that the ratio (concentration ratio) between a solid component concentration in a hydropolymer as formed by the polymerization and a solid component concentration in the aqueous monomer solution will not be less than 1.10; and (3) the solid component concentration in the hydropolymer as formed by the polymerization is not more than 80 weight %.
