Filed: 1987-03-13
Abstract: PURPOSE:To prevent the generation of excessive heat stress in a simple construction by interposing a ceramics spring in at least one position between a blade and upper/lower side walls so as to absorb relative-displacements in the radial direction among all components. CONSTITUTION:The upper and lower portions of a blade 1 are respectively held by means of upper and lower side wall plates 2, 3 so as to form a radial passage. And then, upper and lower side walls 4, 5 are abutted to the upper and lower surfaces of the upper and lower side wall plates 2, 3, respectively, and respective projections 8, 9 are engaged with the retainer ring 10 and the support ring 11 of a gas turbine casing so as to form a blade body. In this case, a ceramics spring 13 is, for example, fixed via a flat plate seat 14 on the upper surface of the upper side wall 4. And further, the head portion of a bolt 12 is fixed to the outer surface of the lower side wall 5, wherein the bolt 12 is fitted by passing through the central portions of respective components. Therefore, the spring 13 can absorb relative-displacements in the radial direction among all components.

Abstract: PURPOSE:To always obtain a high-quality image by surely preventing toner and carrier from scattering from a developing unit to a periphery with the aid of a simple means at the time of attaching and detaching the developing unit in a device main body. CONSTITUTION:When the developing unit is made to slide on a pedestal to be set at a specified position, a gear 501 resists a spring 502 and is pressed to a member 511 to move on a shaft 500 to the right. Then, the gear 501 is disengaged from a gear 504 incorporating a one-way clutch 505 but it is still engaged with a gear 104 for driving a developing sleeve, gears 506 and 508 for driving screws 107 and 108 and an idle gear 509. In the case of detaching the developing unit, the unit is moved to the left. The gear 501 is pressed to the member 511 by the spring 502 to move to a stop ring 503 on the shaft 500 and then it is shifted to the right with the developing unit. Finally, the gear 501 is engaged with the gear 504 incorporating the one-way clutch 505 completely, so that the rotation in a direction C is inhibited. Therefore, the stain in a machine and the mixture by napped developer on the sleeve are not caused at the time of detaching the developing unit.
