IPC: G03G15/16
Filed: 2001-08-20
Abstract: PROBLEM TO BE SOLVED: To restrain the deterioration of an image by keeping the load fluctuation of an image carrier to an endless belt constant and making the elongation of the endless belt or slide thereof to a driving roller small. SOLUTION: The tooth number of photoreceptor gears 18Y, 18M, 18C and 18B fixed on photoreceptors 3Y, 3M, 3C and 3B is different respectively and set so that it may be smaller in order toward the belt carrying direction of an intermediate transfer belt 2. Assuming that the surface speeds of the photoreceptors 3B, 3C, 3M and 3Y are V1, V2, V3 and V4 respectively, relation between the surface speeds holds V1<V2<V3<V4 because the diameters of the photoreceptors 3B, 3C, 3M and 3Y are the same. Assuming that the carrying speed of the belt 2 is Vb, the relation becomes Vb>V4, that is, Vb is higher than the surface speed V4 of the photoreceptor 3Y near to the driving roller 2B on the most downstream side in the belt carrying direction.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of components of a light source device with a chip LED as a light source to miniaturize the light source device, to simplify assembling work, and to increase the use efficiency to realize the light source having high light intensity. SOLUTION: This light source device has the chip light-emitting element (LED) 311 as the light source; and a circuit board mounted with the light- emitting element 311, having wiring for supplying power to the light emitting element 311. The circuit board is configured as a reflection mirror 312 reflecting the light emitted from the light-emitting element 311. The reflection mirror 312 has a base 313 of a light reflection material such as a metal, and a conductor wiring 315 electrically connected to the light-emitting element 311 is formed on the surface of the base 313. Thereby, a circuit board for disposing the light- emitting element 311 inside the reflection mirror 312 is eliminated to reduce the number of the components and to simplify the assembling work.  Because the light emitted from the light-emitting element 311 is reflected by the reflection mirror 312 without being shielded by the circuit board, the efficiency of the light from the light-emitting element 311 can be improved.

Filed: 2001-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a demanganese method for treating of cast iron at a low cost by which the manganese contained in molten cast iron using steel scrap as melting raw material can efficiently be removed. SOLUTION: Into the molten cast iron containing the manganese, a demanganese-treating agent containing sulfur is added and manganese sulfide is floated up to remove the manganese from the molten cast iron. As the demanganese-treating agent, it is desirable to contain a sulfur content satisfying [added S amount (%)]>[Mn content (%) in the molten cast iron - the targeted Mn content (%)]×0.6. Further, the reaction of the manganese and the sulfur in the molten iron and the floating-up and the removal of the produced manganese sulfide are promoted, and also, excess dissolved S can not be remained by stirring the molten cast iron. In this method, the excess Mn exerting adverse influence on the quality of the cast iron can easily be removed.
