Filed: 1990-03-12
Abstract: PURPOSE:To prevent the leakage of developer by forming notching from the tip of an elastic blade at a position opposed to a boundary between a developer carrying area on a center side in the longitudinal direction of a developing roller and a developer non-carrying area at the end thereof. CONSTITUTION:The respective parts opposed to the developer carrying area X on the center side of the developing roller 11 and the developer non-carrying area Y at the end of the roller 11 independently press-contact with the developing roller because of the division by the notching 86 which is formed from the tip of the elastic blade 41. Therefore, even when a level difference Z is caused between the areas X and Y by the thin layer of developer formed in the area X on the roller 11, the respective parts individually contact with them without influencing each other because of the division by the notching 86, and they press-contact with both of the areas X and Y having the level difference of the roller 11 without a gap. Therefore, the developer is surely prevented from leaking from the gap between the blade 41 and the area X.

Title: Torque limitter
Inventor: OKAMOTO YUJI
IPC: F16D7/10
Filed: 1990-03-13
Abstract: PURPOSE:To prevent the change of the deflection amount of a spring and ON- OFF torque by pressing rollers between clutch cam surfaces and inner members in a biting direction, and arranging holding faces of the spring on outer and inner rings. CONSTITUTION:A shaft 21 is, in general, rotated in a direction of an arrow A, then the rotation is transmitted to an outer ring 11 through rollers 15. When the shaft is rotated in a direction of an arrow B, the shaft 21 is run idly, so that rotation transmission to the outer ring 11 is interrupted. Thus, a clutch shows its function only in one direction. When a wedge angle of a clutch cam surface 12 and force of a spring 17 are adjusted, it is possible to set ON-OFF torque against the rotation of the shaft 21 in the direction of the arrow B. As a result, a one-way torque limitter which has function for preventing reverse rotation and can set a racing torque is constructed. Housing parts 23 are directly formed on the outer ring 11 continuously to the clutch cam surfaces 12. The end of the housing part 12 is the holding face 18 of the spring 17, so that the distance between the roller 15 and the holding face 18 of the spring 17 is kept constant, and the change of the ON-OFF torque is prevented.

Abstract: PURPOSE:To prevent the deterioration in a nonlinear optical effect and electrooptical effect by laminating a ferroelectric thin film consisting of the single crystal of a ferroelectric substance having the same crystal structure on a single crystal substrate and providing a low-refractive index layer in this thin film. CONSTITUTION:The substrate 1 and the ferroelectric thin film 2 are constituted of the single crystals having the same crystal structure and, therefore, the optical waveguide 4 can be formed of the single crystal of the ferroelectric substance having good quality. The low-refractive index layer 3 having the refractive index smaller than the refractive index of the thin film 2 is provided in the thin film 2 and the upper part of the low-refractive index layer 3 in the thin film 2 is used as the optical waveguide 4 and, therefore, only the thin film 2 consisting of the good-quality single crystal is usable without using the thin film having the poor crystallinity, etc., near the boundary of the substrate 1 and the thin film 2. The substrate 1 for forming the optical waveguide 4 is selectable from the substrates of the single crystals having the same crystal structures as the crystal structure of the ferroelectric thin film regardless of the magnitude of the refractive index and the light absorption to the optical waveguide and, therefore, the inexpensive production of the optical waveguide is possible.
