An output circuit of a push-pull type is disclosed. The output circuit includes first and second transistors connected in series, means responsive to a data signal for producing true and complementary signals of the data signal, and means for supplying the true and complementary signals to the first and second transistors. The output circuit further includes means for generating one-shot pulse at a transition time when the true and complementary signals are changed in their logic levels and means response to said one-shot pulse for turning said first and second transistors OFF. A large current flowing at the transition time is thereby prevented.

A sheet-fed offset rotary printing press with a convertible press mechanism includes a chucking cylinder, convertible cylinder, grippers, and air nozzles and blowing ports. The chucking cylinder conveys a sheet by holding its leading edge. The convertible cylinder is arranged downstream of the chucking cylinder in a sheet convey direction and holds a trailing edge of the sheet being conveyed by the chucking cylinder. The grippers cause the convertible cylinder to hold the sheet in a turned state when the sheet is to be transferred from the chucking cylinder to the convertible cylinder. The air nozzles and blowing ports are arranged at different heights on outer sides of two ends in a widthwise direction of the sheet, and blow air toward a center in the widthwise direction of the sheet which is turned over by the grippers, so as to separate the sheet from the chucking cylinder.

A method of fabricating a deflection aperture array used in an electron beam exposure apparatus and a wet etching method and apparatus for fabricating the deflection aperture array are disclosed. In wet etching an aperture array substrate, a jig is used for holding the substrate in such a manner that only a portion of the reverse side to be etched is exposed to an etching solution so that the surface protective film can be removed before wet etching. According to the wet etching method, a gas is introduced into or discharged from an enclosed spacing facing a non-etched surface thereby to adjust the internal pressure of the enclosed spacing. The internal pressure of the enclosed spacing is thus detected and held at a predetermined value in accordance with the detected pressure.

摘要:
A transmission mask for a charged particle beam exposure apparatus that includes a mask substrate having a plurality of apertures arrange in a matrix and a pair of deflection electrodes at each aperture on one surface of the mask substrate. A beam shield layer having a reflectivity to the charged particle beam greater than the mask substrate is positioned on the other surface of the mask substrate. The transmission mask is installed in the apparatus so that the beam shield layer is oriented towards the charged particle beam to prevent an increase in temperature due to irradiation of the charged particle beam.
