Title: Image forming device
Inventor: NAKAI JUNJI
IPC: B65H7/02
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To prevent quality from being lowered because the kind of paper is unknown when the paper is continuously passed and to enhance productivity when an image forming action such as a copying action is executed by delaying the feeding of the next transfer paper by a control means until an image detecting condition is changed according to the paper-kind information of the first transfer paper detected by a paper-kind detection means. SOLUTION: The size of the passed transfer paper is checked after the copying action is started. In the case that the kind of the transfer paper is different, a quantity of heat supplied from a fixing roller 21 becomes different. When the width of a nip part interposed by a pair of the fixing roller 21 and a pressure roller 24 is fixed, the temperature fall and the temperature gradient of the plain paper are set corresponding to the size of the passed transfer paper and the heat source 22 of the roller 21 is turned off in a fixed time while the transfer paper is continuously passed. Since heat is not supplied by the heat source 22 of the roller 21 meanwhile, it is supplied to the transfer paper only by the heat reserved by the roller 21.  Then, temperature change is detected and the temperature gradient obtained when the transfer paper is actually passed is calculated so as to judge whether the transfer paper which is passed is the thin paper or the cardboard.

Abstract: PURPOSE: To make it possible to prevent the deterioration of electronic transportation characteristics by restricting the transition caused by a graded buffer layer or the propagation of lattice defects to an upper layer by changing in stages the lattice constant of superlattice from the lattice constant of a substrate to the lattice constant of an operation layer. CONSTITUTION: An InAlAs/InGaAs superlattice graded buffer layer 102 is inserted between InP substrate 101 and InGaAs operation layer 103, and the InAlAs/InGaAs superlattice graded buffer layer 102 is constituted in such a manner that the constituents in neighboring layers are not the same. And the lattice constant of the InAlAs/InGaAs superlattice graded buffer layer 102 is constituted in such manner that it changes in stages from the lattice constant of the InP substrate 101 to the lattice constant of the InGaAs operation layer 103. By doing this, the transition caused by the InAlAs/InGaAs superlattice graded buffer layer 102 or the propagation of lattice defects to an upper layer can be restricted and the deterioration of electronic transportation characteristics can be prevented.

More specifically, liquid supply is reduced by stopping the motor M or decreasing the r.p.m. thereof.  According to the arrangement, the material S to be separated is prevented from flowing over the bucket cell 2.
