Title: Electrode structure
Inventor: KODERA HIDETOSHI
IPC: H01J31/12
Filed: 1984-06-27
Abstract: PURPOSE:To make a good focusing characteristic securable, by making up an outlet form of each electron transmitting hole of an electron takeout electrode into non-axisymmetry being different from an inlet form. CONSTITUTION:An outlet form of an electron transmitting hole 4a of an electron takeout electrode 3 is made up into non-axisymmetry being different from an inlet form. In this case, the inlet form is made up into a circle while the outlet form into a long oval respectively, and an interval between them is connected with a smooth secondary curved surface. When this electrode 3 is used, focusing lens action in a horizontal direction in and around an outlet of the electron transmitting hole 4a is weakened to some extent but the focusing lens action in a vertical direction grows strong. As a result, a horizontal focusing position becomes more distance but a vertical focusing position comes nearer the other way. And, as for the horizontal direction, electron beams will no longer pass through the vicinity of an outlet angle of the electron transmitting hole 4a in consequence, so that the focusing position is controllable, thus a good focusing characteristic is securable.

Title: Method for stabilizing power system
Inventor: SATO MASAHIRO
IPC: H02J3/24
Filed: 1992-04-24
Abstract: PURPOSE:To avoid a useless unstable state in systems, by shutting off a generator or stopping the shut-off state according to the difference of seriousness degrees between an expected accident and an actual accident. CONSTITUTION:An expected accident analyzing unit 3 judges a stability degree by assuming an accident place, the sort of accidents, and its duration. When the accident is judged unstable, the analyzing unit 3 determines the necessary number of generators to be shut off, and provides the accident conditions and the necessary shut-off number to an accident judgement unit 4, which stores these data. The accident judgement unit 4 detects an accident during a real time operation, and judges whether the degree thereof is equal to that of the expected accident. If it is almost the same degree, the accident judgement unit 4 provides a shut-off command to a shut-off unit 5. In this way, the shut-off unit 5 receives the output from the accident judgement unit 4 so as to shut off a given number of generators from a system while the shut-off unit 5 stops the shut-off operation if the actual accident is not more serious than the expected accident. Then, a useless unstable state is avoided in the system, and the power system can be operated efficiently by stabilizing the power system.
