Patent number: 7274017Abstract: Disclosed is an electron beam apparatus and method which can retain the state that minimizes the amount of water content contained at a gap between a high-voltage cable and a high-voltage introduction insulator to thereby prevent creation of high-voltage discharge and current leakage. The apparatus comprises a means for applying a high voltage to an acceleration electrode while eliminating electron release from an electron source and for detecting a change in an emission current corresponding to a change in an acceleration voltage at this time. In addition, the apparatus comprises a means for issuing a cautionary notice or warning when the change of this emission current exceeds a prespecified value. Further, the apparatus comprises a means for letting a dry gas flow in a gap portion between the electron gun's high-voltage cable and the high-voltage introduction insulator to thereby dehumidify said gap portion.Type: GrantFiled: May 26, 2005Date of Patent: September 25, 2007Assignees: Hitachi High-Technologies Corporation, Hitachi Science Systems, Ltd.Inventors: Akimitsu Okura, Masashi Kimura, Kenichi Hirane, Yoshihiko Nakayama

Patent number: 7071979Abstract: An image sensing apparatus senses an image by illuminating a document by a light source including three light emitting diodes which emit light of red, green, and blue so that the light reflected from the document is incident on a sensor array which in turn generates an electric signal corresponding to the incident light, wherein a predetermined light emitting diode is also turned on during a period in which no image sensing operation is performed thereby making it possible to stabilize the intensity of light illuminating an image. Thus, the invention provides a high-performance and small-sized image sensing apparatus at a low cost.Type: GrantFiled: June 19, 1997Date of Patent: July 4, 2006Assignee: Canon Kabushiki KaishaInventors: Atsushi Ohtani, Yasuhide Ueno, Masashi Kimura

Patent number: 5161084Abstract: A charger for initial charging is built on the surface of a photosensitive drum. A discharge lamp removes the charge from the photosensitive drum. A current detection unit detects the current flowing from the photosensitive drum upon the removal of the charge from the surface of the photosensitive drum by the discharge lamp. A control unit compares a current which is detected by a current detection unit with a reference value which is initially stored in a memory and generates a digital value corresponding to a difference error between them. An A/D converter converts the digital value which is generated from the control unit into an analog current for supply to the first-mentioned charge. The aforementioned process is repeated by an instruction of the control unit until the difference value between the current detected by the current detection unit and the reference value comes within an allowable range.Type: GrantFiled: January 17, 1990Date of Patent: November 3, 1992Assignee: Kabushiki Kaisha ToshibaInventors: Kazushige Morihara, Masashi Kimura, Shin Yamauchi
