Title: Data generator
Inventor: KAGAWA MITSUAKI
IPC: H04L69/40
Filed: 1988-09-30
Abstract: PURPOSE:To generate two kinds of burst data in which a data before and after a burst are continuous and discontinuous by switching a 1st mode interrupting a reset pulse and a 2nd mode applying the reset pulse to an address counter during the burst period and setting the counter to a prescribed data address. CONSTITUTION:When a mode switching means 10 switches the 1st mode into the 2nd mode and a gate signal 8a goes from a low level to a high level, a clock signal (a) is inhibited and a reset pulse 9A (B pulse) is generated from a reset pulse generating means 9 synchronously with the rise of a synchronizing gate signal 8a. In the case of the 2nd mode, since the reset pulse 9a (B pulse) is fed to a reset terminal of an address counter 4, the count changes from '8' to '0' and the counter holds the value till the synchronizing gate signal 8a changes from a high level to a low level. Then the clock inhibit is released by the gate signal (b) and when the clock signal (a) is inputted, the count is counted down sequentially from the starting of a preset value '10'.

Abstract: PURPOSE:To obtain a highly efficient and simple-structured ion thruster by forming notches, which act as a spring mechanism, in the circumferential direction at the periphery of an electrode plate for acceleration and by absorbing thermal expansion. CONSTITUTION:A plurality of notches 21 are provided in the circumferential direction at the periphery of the part, in which electrode holes 9 are made, of a thin, electrode plate 4a forming an electrode for acceleration. Owing to these notches 21, a plurality of springs are formed at the periphery of the electrode plate 4a. A screw goes through a hole 24, which is made at the tip part of each spring piece 22, in order to fix the electrode plate 4a at an electrode plate supporting part to a degree that spring action of the spring piece 22 is not impaired. With this constitution, the radial elongation of the electrode plate 4a due to thermal expansion is absorbed by the gap of the notch 21. Thus, the axial elongation of the electrode plate 4a is restricted to a small amount. Accordingly, the variation in the gap among a plurality of electrode plates becomes small. As a result, the efficiency of the thruster is improved, while the working in manufacturing the thruster can be simplified.
