An image display apparatus uses electron-emitting devices each having: a pair of device electrodes on an insulating substrate; and an electroconductive film connecting the device electrodes. The insulating substrate has concave portions in a gap between the device electrodes. The film has opening portions having a first gap in a region adjacent to the opening portions along such a gap. A carbon film having a second gap is formed in the first gap and has extending portions extending from side surfaces of the concave portions toward the bottom. The extending portions of the adjacent carbon films are not coupled.

The present invention provides an electron-emitting device which does not need a fresh electrode to be added thereto, has excellent convergence and shows little change of a discharged electric current for short and long periods of time, and an image display apparatus using the device. The electron-emitting device includes at least a pair of device electrodes formed on an insulating substrate, and a plurality of electroconductive films which are formed so as to connect the device electrodes to each other and have gaps therein, wherein the surface of a region which is at least adjacent to the gap between the electroconductive films and is not covered with the electroconductive film is higher than the surface of the electroconductive film.

A base body includes a first part and a second part. The second part has a lower thermal conductivity than the first part and is arranged adjacently to the first part. A first conductive film is formed on the first part and a second conductive film is formed on the second part. At least part of a gap is located above a boundary between the first part and the second part.

In a driving method for an electron-emitting device in which an electron-emitting member made of an aggregate of carbon fibers is made to emit electrons by a voltage being applied between a cathode electrode on which the electron-emitting member is formed and a counter electrode disposed in opposition to the cathode electrode, a driving voltage V smaller than a maximum applied voltage Vmax is applied between the cathode electrode and the counter electrode to drive the electron-emitting device, the maximum applied voltage Vmax being a maximum voltage applied between the cathode electrode and the counter electrode before the start of driving.

An arbitration device comprises a determining unit that determines priority of each of a plurality of electrical devices according to at least either a position or an action status of a person present in a target area for control; and a calculating unit that calculates electrical power to be allotted to each of the electrical devices in such a way that a total of electrical power allotted to a plurality of the electrical devices is within a limit value and the electrical devices having the priority at high levels are allotted with electrical power on a priority basis.
摘要:
A phase voltage setting unit is configured to define an actual current phase region including a current phase error range based on parameters to which is added an individual difference of at least any one of a motor and an inverter. The phase voltage setting unit defines a stable operation current phase region in which a rotor position can be detected through sensorless control, and sets, as a target current, an electric current obtained by adding a phase difference corresponding to the number of revolutions detected by the revolution number detecting unit to an electric current set by current vector control, such that the actual current phase region is within the stable operation current phase region.
