Title: Leakage transformer and its heat resisting and insulating method
Inventor: AMANO MASATETSU
IPC: H01F27/32
Filed: 1991-06-12
Abstract: PURPOSE:To reduce stock costs of semi-finished products by improving both job efficiency and working environment of an insulating process for a leakage transformer. CONSTITUTION:A coil 2 is housed in a case 1, and after remaining room between the coil 2 and the case 1 is filled with a filler 8 while the case 1 is vibrated, a heat resisting insulation resin 9 is injected into the filler 8 under vacuum so as to regain a normal pressure, and at the same time, the resin 9 is soaked in the filler 8 and then heated for hardening of the resin 9. By these processes, the grain size of the filler 8 can be made larger, resulting in suppressed splashing of the filler 8 at filling along with improved working environment. Since the resin 9 is soaked into micro voids both in the filler 8 and between each portion of a coil 2, a varnishing process can be omitted for improved work efficiency. The stock of semi-finished coils is not required, resulting in reduced stock costs of semi-finished products.

Abstract: PURPOSE:To reduce remaining developer and to restrain napping so that irregularity in an image is prevented by displacing a magnet inside a developer carrier so that a magnetic force horizontal component in the vicinity of a point close to an image carrier becomes large at the time of non-developing. CONSTITUTION:Developer is recovered from a developing sleeve 31 at the time of finishing of developing, carrier remaining on the developing sleeve 31 is influenced by the magnetic fields of the magnets 71-73, especially by the magnetic field in the vicinity of a main pole 72 on a developing area in which failure occurs. That is, the chain of the carrier is formed and brought into contact or to come close to a photosensitive drum 17. Then after cutting the nap of the developer, the main pole 72 is displaced in the rotating direction on the upstream side of the developing sleeve 31 by an angle beta (beta>alpha) from a line connecting the center of the photosensitive drum 17 with that of the developing sleeve 31, so that the horizontal component of the magnetic field caused by the main pole 72 and the magnetic pole 73 on a downstream side becomes maximum. The horizontal component is the component in a direction at nearly orthogonal to the line connecting the center of the photosensitive drum 17 and that of the developing sleeve 31. Thus, the remaining carrier lies down by an intense horizontal magnetic field.

Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To dispense with the needless take-up margin of a photoreceptor sheet by stopping a take-up device when a fixed time elapses after a sensor detects the boundary between a used photoreceptor area and an unused photoreceptor area. SOLUTION: The surface of the photoreceptor sheet is smooth just after taking up the photoreceptor sheet and the level of reflected light therefrom is low, but the surface of the photoreceptor sheet just after taking-up after the sheet is used by a specified amount is rough because of the rubbing with printing paper, a developing device and a cleaning device, and the level of the reflected light becomes higher than the initial state. By actuating the sensor in the midst of the take-up operation of the photoreceptor sheet, the boundary 5 between the used part 3 to be taken up and the unused part 4 to be submitted for use of the photoreceptor sheet is detected using the output from the sensor.  In such a case, after the sensor detects the boundary 5 between the used part 3 and the unused part 4 of the photoreceptor sheet, the take-up device is actuated until the used part 3 is taken up to the inside of a pipe stock. After a specified time elapses, the take-up device is stopped.
