Title: Image forming device
Inventor: NEMOTO HIDEO
IPC: G03G21/00
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To prevent a sheet of paper whose both surfaces are already printed from being erroneously printed, even if this paper coexists in a paper feeding tray by deciding whether the front and rear surfaces of the paper are already printed or not. SOLUTION: When the top end of the paper reaches an image detecting part 134A, this image detecting part 134A is started to scan a surface subject to the printing from its top end to its rear end, so that the face that the surface subject to the printing is already printed or not is detected to inform an engine detecting part 131. This engine detecting part 131 starts a printing part 132, when it is decided that the surface subject to the printing is of a 'black paper', by referring to the result of the detection. Therefore, a toner image formed on a photoreceptor drum 203 is transferred onto the arrival paper and further, toner is fixed by a heating roller 204.  On the other hand, when the result of the decision is recognized as 'the presence of an image', the printing part 132 is instructed to stop the printing, for stopping a printing operation and the paper is carried to a paper reverse part 135A.

Title: Auto-transformer with demagnetization circuit
Inventor: TAKAHASHI ISAO
IPC: H01F30/02
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To eliminate a difference between input and output by installing demagnetization winding to demagnetize an excited core. SOLUTION: An auto-transformer with a demagnetization circuit is formed by wrapping insulating paper 2 around a core 1, and forming demagnetization winding 3, shunt winding 4 and series winding 5. The terminals of the demagnetization winding 3 are connected with switches 8, and the terminals of the shunt winding 4 are connected with a switch 9. These windings may be basically formed in any order. Since the wire diameter of the series winding 5 where load currents are passed is larger than that of the demagnetization winding 3 and the shunt winding 4, however, the series winding 5 is preferably formed last. Further, a plurality sets of shunt winding 4 can be installed to take out any voltage. Switches containing mechanical contact or semiconductor switches are used for the switches 8 and 9. If input voltage drops when a load is used with transformed voltage, as a result, any difference between input and output is instantaneously eliminated to prevent interference with the load. Thus a transformer applicable to a wide range of use is obtained.
