Title: Sheet for printing
Inventor: FUKUHARA SHOZO
IPC: B42D15/10
Filed: 1992-12-09
Abstract: PURPOSE:To obtain a sheet for printing which facilitates the visual identification of falsifiction when its printed part is scraped off and new letters or numerals are added and is used appropriately for gift certificates, securities, etc. CONSTITUTION:A sheet for printing is composed of a printed image fixing layer 3 placed on the surface of a sheet substrate and a fluorescent coating layer 4 laminated on the layer 3. Information of an amount of money 8 and others is printed on the surface of the sheet to provide a gift certificate 9. When the printed numerals of an amount of money 8 in the gift certificate 9 is scraped off and new numerals are added, since the fluorescent coating layer 4 in the part scraped off is removed simultaneously, the amount of the fluorescent agent is reduced in comparison with another part to decrease the degree of fluorescence. In this way, the visual identification of the falsification can be promptly and easily performed by the comparison of the fluorescence.

Abstract: PURPOSE:To make the winding work of a coil smoother so as to prevent the bending of a conductor and damage to the insulating coating of the conductor at the time of winding a coil by forming at least the inner cross section of the coil winding section of a core formed by winding the coil around a magnetic steel plate in a circular shape. CONSTITUTION:The tittle core 1 is formed in an angular pipe having a center hole 1b and one side of the core 1 which becomes a coil winding section 1c is formed to have a nearly circular cross section. The core 1 is formed in such a way that a magnetic steel plate 1a is rolled up with a rolling device and formed in the angular pipe having an almost square cross section, the corner sections 1a around the coil winding section is removed with a grinding machine etc., until the cross section becomes circular. Since at least the inside of the coil winding section facing the hole 1b is formed to the circular shape, the coil winding work with a bobbin can be smoothly performed and, at the same time the winding speed is increased. In addition, the forcibly bending points of the coil is reduced and the occurrence of damages to the insulating coating of the conductor used for the coil is also reduced. Moreover, since the circumferential length of the coil winding section is reduced, the length of the coil required for the same number of turns is reduced.

Abstract: PROBLEM TO BE SOLVED: To separate and store such a foreign matter as paper powder included in recovered toner, also to simplify a constitution and to reduce a cost by providing a tray member on a position just under a pressure relief filter provided on the casing of a developing device. SOLUTION: The recovered toner recovered from a photoreceptor includes such the foreign matter as paper powder, and reversely electrified toner. The foreign matter is sucked by using the pressure relief filter 11 and also the sucked foreign matter is captured and held by the tray member 14 provided on the position just under the filter 11 so as to be removed from the developer. That is, when internal pressure inside the casing becomes high in the middle of the driving of the developing device 4, air goes outside from the filter 11, and such the foreign matter 13 as the paper powder suspending inside the casing is sucked as the air moves.  One part of the foreign matter 13 adheres to the filter 11, and the other part freely drops inside the casing; however, since the member 14 is arranged on a foreign matter dropping path just under the filter 11, mixing of the foreign matter in normal developer can be prevented.
