Title: Chart display device
Inventor: KUGA HIROMI
IPC: G09B29/10
Filed: 1993-12-27
Abstract: PURPOSE:To automatically change over a chart shown on a display by making a comparison between that chart and a candidate chart containing the position of an own ship for selecting a chart having higher accuracy. CONSTITUTION:A chart selector device 5 compares a displayed chart with a candidate chart containing the position of an own ship, and selects a chart of higher accuracy. In other words, a ratio X=CB/AC of chart range reference values (CA and CB) of the displayed chart and the candidate chart is calculated, provided that the number of candidates as automatically selected candidates is set to 'n' and the value of (i) is initially set to 1. Then, both displayed and candidate charts are compared in terms of accuracy on the basis of a comparison between the ratio X and a reference ratio X0 (preferably 0.8). If X is less than 0.8, the candidate chart is judged to have high accuracy and selected as a selective candidate. If the value is larger than 1.25, the candidate chart is excluded. Also, accuracy is judged to be equivalent, when the value of X is between 0.8 and 1.25, both inclusive. For each of the charts, then, the length (1A and 1B) of rectilinear lines drawn toward the bow of the own ship and included in the charts is calculated. If 1A is less than 1B, the displayed chart is selected. Furthermore, if 1A is equal to or larger than 1B, the displayed chart is excluded, and (i=i+1) is adopted. This process is repeated over the range of i=1 to i=n. The chart is, then, changed over to finally selected chart data at a process 6 and displayed at a process 7.

Title: X-ray image tube
Inventor: TAKASE KINJI
IPC: H01J31/50
Filed: 1999-12-08
Abstract: PROBLEM TO BE SOLVED: To provide an x-ray image tube wherein the stability of electron orbit is aimed at and a clearer picture is obtained. SOLUTION: In addition to an anode 4 constituting an electronic lens system within a side tube 2 of the x-ray image tube 1, a barrel shape of electrode 11 is disposed in front of a micro channel plate(MCP) 10 so that a stability of electron orbits between the anode and the MCP is aimed at. Since the MCP has a function for multiply increasing photoelectrons, when unstable electron images are formed on the MCP, the disturbance of images is increased several times. The tubular electrode is disposed between the anode and the MCP, an electron incidence surface 10a of the anode and the MCP becomes identical electric potential through the barrel shape of electrode, and as a result, the stability of electron orbit can be realized between the anode and the MCP.  Further as a result of disposing the barrel shape electrode, it is expected that an influence of an electric field invading into the tubular electrode on the electron orbit is reduced by the tubular electrode, and a clearer picture can be obtained even from a feeble x-ray.
