Title: Method of controlling electrophotographic image printing and recorder using the same
Inventor: MITSUYA TERUAKI
IPC: G03G15/00
Filed: 2001-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a highly accurate film thickness detecting method for a photoreceptor and to provide an image printing control method and a recorder which secure temporally stable image quality to all image patterns even if the deterioration of the photoreceptor occurs. SOLUTION: A surface potential sensor is placed behind the developing device in the rotating direction of the photoreceptor, and the photoreceptor film thickness is detected from the change of the electrical potential of the electrostatic charge region. Moreover, the development potential on the surface of the photoreceptor is kept stable with time by applying feedback control to the electrical potential on the surface of the photoreceptor. The film thickness of the photoreceptor is detected and the exposure is applied with auxiliary light quantity only to the region in which the potential distribution of the photoreceptor changes from the electrification potential to the discharge potential.

Filed: 2001-06-04
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor package that can reduce the working load and, at the same time, does not produce cutting burrs, when the package is cut off from a lead frame. SOLUTION: The semiconductor package 8 is formed, by using the lead frame 14 having alit sections 7 on the bottom face sides of cutting sections faced to the end sections of lead terminals 4 and, after a semiconductor element 6 is sealed with a sealing resin 5, the package 8 is cut off from the lead frame 14. Since the cutting sections of the lead frame 14 have thin thicknesses, the working load can be reduced, and the occurrence of cutting burrs at the front ends of the lead terminals 4 can be suppressed, when the package 8 is cut off from the lead frame 14. In addition, since the slit sections 7 are filled with the sealing resin 5 when the semiconductor element 6 is sealed with the resin 5, the lead terminals 4 are also fixed with the resin 5 which fills the slit sections 7.  Consequently, the junctions between the terminals 4 and resin 5 become firm and peeling off of the terminals 4 and the chipping of the sealant can be suppressed further, when the package 8 is cut off from the lead frame 4.
