Title: Electrostatic recorder
Inventor: SHIMIZU SHIGERU
IPC: G03G15/05
Filed: 1989-10-27
Abstract: PURPOSE:To stably obtain an image of high resolution without wearing out a printing head by driving a controlled electrode at a low voltage and controlling it according to recording information while a high-pulse voltage of a fixed cycle is applied to the part facing an electrod. CONSTITUTION:A developing roll 6 is rotatably provided in a toner carrier 3. In the roll 6, a magnet roll 6b is firmly fixed to the inner surface of a cylindrical screw pole 6a spirally equipped with a linear electrode. A cylindrical electrode 8 is oppositely disposed at a prescribed distance away from the pole 6 via the carrier 3. While the electrode 8 and the roll 6 are driven and rotated clockwise by applying a rectangular high voltage pulse to the linear electrode of the pole 6a, a recording pulse voltage is controlled to form the image on the controlled electrode 4 according to recording information. Consequently, a toner recorded image corresponding to the recording information is formed on the peripheral face of the electrode 8. By such a method, a high-resolution, recorded image made of sharp dots can be obtained stably and efficiently under a low voltage.

Abstract: PURPOSE:To increase a shooting time, to apply uniform dose of a beam reduced in its constant current density to all patterns, and to form the pattern with high dimensional accuracy by calibrating the beam size of a variably forming beam having a constant current density, and then increasing the beam having a predetermined size or less as compared with a predetermined size by correction. CONSTITUTION:A beam current distribution of a pattern of three beams having beam size L1 in which the shape of a current distribution becomes a triangle ABC is shown. In this case, only dose D1 is obtained by the pattern. Then, the current distribution is so corrected to the beam of a triangle PQR that the beam size becomes L2, it is superposed, and lithography is conducted to obtain a predetermined dose D0. Its correction amount becomes L2=(L0+L1)/2. When a beam shooting time is increased for the beam reduced in its current density to be superposed with the beam of the triangle PQR and exposed, a predetermined dose D0 is obtained. In order to obtain the dose D0, t1=(L0/L)t0 is set, where L is the beam size of L0 or less, and t0 is predetermined shooting time.
