    摘要: To provide a luminance adjusting apparatus making it possible to narrow the output dynamic range of a picture signal processing section and decreasing the cost of a horizontal driver. The following are arranged: a variable gamma correction circuit (12) for synchronously changing an inflection point of a gamma correction curve and a common voltage generated by a common voltage control circuit (7) by the fact that a luminance adjusting dial is adjusted, a timing signal processing circuit (3) for generating a timing pulse, a picture signal processing circuit (5) for processing a picture signal, a horizontal driver, a common voltage generation circuit (7) for generating a common voltage, a vertical driver (8), and a common driver (9). A picture signal is inputted to the variable gamma correction circuit (12) from a signal source and the inflection point of the gamma correction curve and the common voltage generated by the common voltage control circuit (7) are synchronously changed by manually adjusting the luminance adjusting dial.

    摘要: A system for mounting a hub to an optical disk comprises a turntable arranged on an X-Y stage, a loading rod arranged above the turntable and extending vertically, a chuck provided at a lower end of the loading rod, for holding the hub with the axis of the hub aligned with a reference line as the axis of the loading rod, and a pair of displacement sensors for detecting a deviation of the axis of the turntable from the reference line, whereby the X-Y stage is driven in accordance with the signal from the displacement sensors, to position the turntable such that the axis of the turntable is aligned with the reference line. Thereafter, the optical disk is placed on the turntable with the axis of the optical disk aligned with the axis of the turntable, and the hub is placed on the optical disk through an ultraviolet-curing adhesive, by using the loading rod, with the axis of the hub aligned with the axis of the turntable. The system further comprises an ultraviolet radiation device for emitting an ultraviolet radiation onto the adhesive.
