摘要： An electron-beam exposure system includes an astigmatic compensation circuit that increases a voltage applied across a pair of electrodes forming an electrostatic sub-deflector and simultaneously decreases a voltage applied across another pair of electrodes forming the same electrostatic sub-deflector with a same magnitude as in the case of increasing the voltage, wherein the magnitude of the voltage change is changed in response to the deflection of the electron-beam caused by a main deflector.

摘要： A charged particle beam exposure system is directed to an exposure process of an electron beam for sequentially scanning an electron beam employing a blanking aperture array including a plurality of blanking apertures. The system facilitates re-focusing for compensation of focus error due to Coulumb effect and makes wiring the blanking aperture array easier. The system further allows exposure without an irradiation gap. The blanking aperture array 6 is formed with a plurality of said blanking apertures 62 arranged in a two-dimensional configuration. A control system 24 controls the blanking aperture array 62 to set the blanking aperture to the ON state where the charged particle beams pass through the blanking aperture and reach the object 19 to be exposed or the OFF state where the charged particle beams cannot reach the object 19 to be exposed. The other control system of the control means performs a control so that a plurality of said charged particle beams that have passed through different blanking apertures of said blanking aperture array overlaps and is irradiated a plurality of times onto the specified position or the peripheral position in the vicinity of the specified position of the object to be exposed to the charged particle beams.

摘要： A universally articulable supporting sheath comprises an interconnected series of links, each having a convex spherical surface at one end, and a concave spherical surface at its opposite end. The concave and convex surfaces mate with one another to form the sheath. Special links having branch openings may be provided. Various forms of waterproofing seals are provided, including O-rings, axially compressed rings, flexible belts, and ridges on the spherical surfaces. The links can be fitted together by thermal expansion. However, an axially split link is also described, which comprises two parts which snap together. The split parts may be molded as a unit with an integral thin wall hinge. The bending characteristics and bending radius of a sheath can be modified by insertion of spacers between the links at selected locations, or by the insertion of pins into radial holes provided in the links. Spacers with tongues may be used to prevent rotation of the links about the sheath axis, while allowing unidirectional articulation. Projections on one of a pair of mating spherical surfaces can be engaged with holes, slots or recesses of rectangular or other shapes to produce various limits on articulation and rotation. A single link may be provided with several alternatively usable holes, recesses and the like. The outer surface of a link can be provided with an axial extension engageable with a surface of an adjoining link to prevent back bending, or to prevent bending altogether.

摘要： A paste type lead storage battery having a grid constituted by a grid base formed of a lead-calcium alloy and a layer of lead-antimony-stannum alloy roll-bonded integrally to the grid base on at least one side thereof. Preferably, the grid is formed by expanding a sheet of base material to which the alloy layer is integrally roll-bonded. Portions of the base and the alloy layer that serve as a active material support are both in contact with a paste-like active material, and antimony and stannum coexist in the alloy layer. The charge restoration after standing in a discharged state and the lifetime during cycles of charge and discharge including heavy discharge are thereby improved.

摘要： A method incorporated in a high throughput EB lithography suitable to the fabrication of VLSI semiconductor circuit. The method comprises a step of providing patterns which are delineated to join together with an overlap determined in accordance with the time interval between the respective delineations thereof by using an electron beam having a high current density and/or high energy. When a first and a second patterns having respective edge portions contacting with each other are delineated in the order of the first pattern and the second pattern by respective exposures thereof to corresponding at least single shots of an electron beam, at least one of the first and second patterns is extended in the direction perpendicular to the edge portions so that the patterns are provided with an overlap with the amount determined in accordance with the time interval between the respective shots of the electron beam to said edge portions.

摘要： A transistor circuit with hysteresis operation, which is formed with a detector part and selector part. The detector part detects a change in the level of an input signal according to one of first and second threshold levels, and generates an output signal having a level corresponding to the input signal. The level of the input signal is changed between a first level and a second level which is lower than the first level. The first and second threshold levels fall within a range defined between the first and second levels. The selector part selects one of the first and second threshold levels in accordance with the level of the output signal, and applies the selected one threshold level to the detector part.
