摘要:
An imaging apparatus includes an electron emission array having electron sources arranged in matrix form, a photoelectric conversion film opposed to the electron emission array, and a control and drive circuit configured to select one or more horizontal scan lines in a given video signal output period and to cause the electron sources included in the selected one or more horizontal scan lines to emit electrons toward the photoelectric conversion film, wherein the control and drive circuit is further configured to cause the electron sources included in the selected one or more horizontal scan lines to emit electrons toward the photoelectric conversion film in any one or more blanking periods excluding both a blanking period immediately following the given video signal output period and a blanking period immediately preceding a next video signal output period in which the one or more horizontal scan lines will be selected next time.

An imaging apparatus includes an electron emission array having electron sources arranged in matrix form and having a plurality of horizontal scan lines, a photoelectric conversion film opposed to the electron emission array, and a control and drive circuit configured to select one or more of the horizontal scan lines in a given video signal output period and to cause the electron sources included in the selected one or more horizontal scan lines to emit electrons toward the photoelectric conversion film to produce a video signal, wherein the control and drive circuit is configured to cause the electron sources included in unselected one or more horizontal scan lines not selected in the given video signal output period to emit electrons toward the photoelectric conversion film in a blanking period immediately preceding the given video signal output period.

In a rotary actuator including a voice coil motor having a coil fitted to the other end portion of a carriage fixed to a rotary shaft and having a load at one of the end portions thereof, the rotary actuator of the present invention is characterized in that the rotation on the coil side and the rotation on the load side with respect to the rotary shaft are balanced. The weight of the coil is adjusted by forming the coil by at least two kinds of coil wires having different specific gravities, and where a plurality of coils are disposed on the outer side of the rotary shaft, the weight of the coil on the load side is made smaller than that of the coil on the opposite side.
摘要:
A metal silicide film is formed on the sides of a polycrystalline silicon layer formed on a semiconductor substrate via an insulating film and the surface of the metal silicide film is covered by a silicon oxide film, whereby the silicon layer has a low electrical resistance and no short-circuiting is necessary. For example, in an insulated gate field effect transistor, the gate electrode is constituted by the polycrystalline silicon layer and the metal silicide film at the side walls of the polycrystalline silicon layer. Such a gate electrode has a low electrical resistance and does not cause undesirable short-circuiting with source and drain regions by the existence of the silicon oxide film formed on the surface of the metal silicide film. Also, other metal silicide film may be formed on the upper surface of the gate electrode. Moreover the silicide-SiO.sub.2 structure may be used on the source and drain regions.
