    摘要: An electron source comprises a plurality of electron-emitting devices and a drive means for driving the devices. The drive means applies a voltage above a threshold level to selected ones of the plurality of electron-emitting devices according to an image signal to cause the selected devices to emit electrons. The drive means also applies a voltage pulse for bringing the plurality of electron-emitting devices into a high resistance state. The voltage pulse for bringing into a high resistance state has a polarity reverse to that of the voltage for causing electron emission and has a voltage rising rate of greater than 10V/sec.

    摘要: An image-forming apparatus comprising an envelope formed of a plurality of members, an electron source arranged within the envelope and an image forming member for forming images by irradiation of electron beams from the electron source is manufactured by heating the plurality of members to bond them together to produce the envelope in an atmosphere containing at least a gas selected from reducing gases, inert gases and non-reducing and non-oxidizing gases or in a vacuum. The electron source comprises preferably an electron-emitting element having a thin film for electron emission arranged between a pair of electrodes.
