Title: Ion flow recording head having angular ion emission port
Inventor: KADOWAKI HIROYUKI
IPC: G03G15/05
Filed: 1993-11-17
Abstract: PURPOSE:To form a shadow part without overlapping adjacent dots by a method wherein an ion flow emitted from an angular ion emission port is controlled by applying a recording signal, voltage between an upper electrode and a lower electrode opposed to each other. CONSTITUTION:An ion emission port 10 is shaped into, for example, a triangular form. By arranging such ion emission ports, triangular dots 11 are formed in proximity to each other. Since the edge part of the dot is a straight line, adjacent dots clan be formed close to each other at a negligible interval. Therefore, a shadow part can be formed without overlapping dots by forming clots sufficiently close to each other. Every ion emission port, shaped into an angular form with straight-line edges can be applied. For example, an ion emission port shaped into a square, a lozenge, or the like can take a similar effect.

A selector 7 is inputted with the outputs of an A/D converter 3 and the converter 6 and outputs either of the two outputs thus inputted by a control signal 104. When a radar is normally operated, the output of the converter 3 calibrates position data from the radar by solar radio emission. At this time, the control signal 104 is given so that the output of the converter 6 is selected as the output of the selector 7. The selection of the converter 6 is equivalent to increase in the number of bits of the converter 6 and in the stages of quantization for the signals of receiver noise, solar radio emission and the like. Accordingly, the position data of the solar radio emission can be extracted.
