Title: Sheet material ejection device for image forming device
Inventor: TAGAMI MASAHIDE
IPC: G03G15/20
Filed: 1990-07-19
Abstract: PURPOSE:To eliminate the curl of a sheet material generated in a fixing process by obtaining such constitution that the pressure roller of a fixing device is moved by interlocking with the switching action of a flapper and a distance between a point where the carrying direction of the sheet material on a path guide member is decided and the tangent line at the nip part of a fixing roller and the pressure roller is changed. CONSTITUTION:When the flapper 32 is switched to a position that a sheet material carrying path B is opened by the selection of face-down ejection, a pinion 46 is rotated in a direction shown by an arrow. Thus, a supporting plate 36 is turned to the position of a chain line where it abuts on a stopper 40. As the result, the pressure roller 21 is moved in the direction of an arrow (b) on the outside circumference of the fixing roller 20 and the distance L1 between the tangent line C and the point P becomes large. Under such a state, the sheet material where the fixing process is finished deeply enters a bending member for rectifying a curl 33 and it is guided to the path B. Then, the sheet material is curled to a side which is opposite to the curl generated in the fixing process. The curl is eliminated because the sheet material is curled again to a printing surface side at the inversion part of the sheet material carrying path B.

The content of the fibers 1 for fusion is preferably 5 to 20% of the entire part. As a result, the cut ends are hardly loosened, unlike heretofore. The suture to the vital blood vessel is easy and the yarn scrap is hardly produced. The possibility of generating the blood vessel occlusion by the yarn scrap after the transplantation to the living body, the leakage of the blood from the sutured part, rupture, etc., is eliminated.

IPC: G01N21/81
Filed: 1992-06-26
Abstract: PURPOSE:To measure humidity accurately even under existence of an infrared ray absorptive gas without being influenced by electromagnetic noise by securing a porous body bearing a moisture-sensitive color-changing substance to the tip of an optical fiber. CONSTITUTION:A visible ray 6 led through an optical fiber 4 is cast onto a porous body which bears a moisture-sensitive color-changing substance 2 secured to the tip of an optical fiber with a clear adhesive 3, and the reflected visible ray 7 is sent to the body of a measuring device upon passing through the optical fiber 4. The substance 2 absorbs part of the cast-on visible ray 6 and reflects the ray 7 not absorbed, when the color of the substance 2 will change with adsorption and separation of the moisture in the air, and therefore, the wavelength of the absorbed visible ray differs depending upon the ambient humidity and also the wavelength of the ray 7 reflected differs accordingly. Because of possibility of using visible rays, the optical loss in the course of optical fiber 4 is lesser to enable measuring in the distance.
