Title: Fixing device for image forming device
Inventor: ECHIGO KATSUHIRO
IPC: G03G15/20
Filed: 1991-03-15
Abstract: PURPOSE:To easily perform the temperature management of a heat source based on the difference of heating directions and to prevent fixing time from being extended when surface heating or back plane heating is selected corresponding to the quality of transfer paper by setting a gap between a presser roller and a heat source roller used in the backplane heating at a value less than a specific value. CONSTITUTION:The presser rollers 4, 5 are comprised of emery rollers on which irregularity are formed, for example, by scattering aluminum particle on the surfaces of RTV rubber rollers, and the gap G between the surface and that of the heating roller 2 is set at a value less than 0.1mm. Ring members 12 with plate thickness equivalent to the gap G are loaded at both terminals in the axial direction of the presser rollers 4, 5 in the gap G, and it can be obtained by abutting the ring member 12 with the circumferential plane of the heating roller 2. By forming the device in such a way, no heat insulating layer exists, therefore, the transfer of heat between the heating roller 2 can be performed satisfactorily, thereby, surface temperature almost equal to that of the heating roller 2 can be supplied to the transfer paper.

Abstract: PURPOSE: To know the optimum magnification of a semiconductor laser having astigmatic difference without correction of astigmatic difference by an optical system by disposing an image forming lens under the specific conditions with respect to the longitudinal direction of the semiconductor laser.  
     CONSTITUTION: When the emission end face of a semiconductor laser is put approximately at the front side focal plane f 1  of a condensing lens 6a and an image forming face 7 is put in the rear side focal position f 2  of the image forming lens 6a, the longitudinal exit beam of the semiconductor laser images on the image forming face 7 as an approximate beam west because its diversion origin positions near the emission end face. On the other hand, the exit light in the transverse direction images on the image forming plane 7 without becomong beam west because its diversion origin is in the position away from the end face and the correction of astigmatic difference. As is not done for the lens system, thus the magnification β of the conjugate face of the laser end face and the recording face is expressed by formula I. Here, F 2  denotes the F number of the image forming lens and constant γ≈2.

Title: Rapidly solidified aluminum powder alloy excellent in room temperature and high temperature strength
Inventor: SUDO SHUNTARO
IPC: B22F1/00
Filed: 1990-03-02
Abstract: PURPOSE:To obtain a rapidly solidified Al powder alloy showing high tensile strength from a room temp. to a high temp. of about 300 deg.C by specifying the content of Si and Fe in an Al-Si-Fe-Cu-Mg alloy. CONSTITUTION:This rapidly solidified Al powder alloy contains, by weight, 5 to 15% Fe, 1 to 8% Si, 1 to 8% Cu, 0.1 to 5% Mg and the balance Al. In this alloy, Fe forms intermetallic compounds with Al, which are finely dispersed at the time of atomizing to increase its high temp. strength. In the case of <5% Fe content, the effect is made insufficient, and even in the case of >15%, the effect is saturated, and furthermore, the intermetallic compounds are largely formed to deteriorate its forgeability. Si enters into solid soln. in Al to strengthen the matrix of Al and to increase its strength, and furthermore, it increases its modulus of elasticity and deteriorates its thermal expansion coefficient. As for the amt. of Si to be added, in the case of <1%, the effect of improving its strength is made insufficient, and in the case of >8%, brittle Al-Si-Fe intermetallic compounds are coarsened to deteriorate its strength.
