Title: Field emission type print head
Inventor: KOBORI YOICHI
IPC: H01J31/12
Filed: 1995-06-28
Abstract: PURPOSE: To eliminate the leakage light emission without narrowing the interval between a cathode and an anode by forming an anode line almost perpendicularly to a gate line, and setting the potentials of non-selected gate leading electrode of alternately selectively driven leading electrodes and two dummy anodes to a low level. CONSTITUTION: When gate lines GT11, 13,..., 1(n-1) of odd numbers and gate lines GT22, 13,..., in of even numbers are alternately selectively driven, the potential of the non-selected gate line is set to a low potential, and hence the selectively driven gate line is narrowed by the gate line of the low potential, and the electrons field emitted from the selectively driven gate line can be concentrated. Since the anode line selectively driven at the anode side is sandwiched by the dummy anodes set to the low potential, the electrons can be concentrated even at the anode side. In this case, since the directions for concentrating the electrons are perpendicularly crossed at the gate and anode sides, it is efficient.

Title: Radar controller
Inventor: WATANABE HARUHIKO
IPC: G01S13/70
Filed: 1989-07-17
Abstract: PURPOSE:To achieve a higher distance tracking performance of a target by a method wherein an overlap between a transmitted pulse and a received pulse is calculated to correct a distance error and a preceding error is outputted when the overlap exceeds a specified limit. CONSTITUTION:In an eclipse detector 13, an overlap between a transmitted pulse 4 and a received pulse 6 as calculated at time (t) is compared with a transmitted pulse width as calculated by a pulse width controller 12 at time t-2. When the overlap exceeds a limit of the transmitted pulse width, an eclipse decider 15 outputs a preceding distance error to a distance tracking servo 14. When the overlap is below the limit of the transmitted pulse width, a distance error corrected by an eclipse corrector 10 at the time (t) is outputted. Then, a distance tracking servo 1 calculates a distance tracking gate control signal to be outputted to a transmitter/receiver 7 from the distance error. This can prevent effect on the distance tracking servo, thereby achieving a higher distance tracking performance of a target.
