Abstract: A fluid filled type vibration-damping device including: an elastic body connecting a first and second mounting member and sealing off one opening of the second mounting member; a flexible film fluid-tightly sealing off an another opening of the second mounting member; a partition member firmly fitted into the second mounting member thereby forming a pressure-receiving chamber partially defined by the rubber elastic body and an equilibrium chamber partially defined by the flexible film, which communicate together via an orifice passage; a short circuit passage is formed to connect the two chambers, and a valve body placing the short circuit passage in a communicating state on a basis of elastic deformation of the elastic body when an excessive pressure differential arises between the two chambers.

Abstract: A fluid filled type vibration damping device includes: a main rubber elastic body elastically connecting first and second mounting members; a partition member supported by the second mounting member; a pressure-receiving chamber partially defined by the elastic body and having a non-compressible fluid sealed therein; an equilibrium chamber partially defined by a flexible film and having the non-compressible fluid therein. The chambers are formed to either side of the partition member and an orifice passage permits a fluid communication between the two chambers. A short-circuit passage is formed so that the pressure-receiving and equilibrium chambers are able to be short-circuited through the short-circuit passage. A valve is used for switching the short-circuit passage, and a metal spring is used for holding the valve in a closed state at a predetermined initial level of elastic deformation.

Abstract: A method for manufacturing a flying type magnetic head slider includes an ion etching step for shaping a surface of the slider facing to a magnetic information medium to form a predetermined pattern by using an ion etching method, a step of forming a protection layer of an organic material to cover at least one face of the slider on which at least one electromagnetic transducer element is formed, by injecting the organic material to the at least one face of the slider from a ink jet type printer head, and a step of removing the protection layer of the organic material. The protection layer forming step is executed before the ion etching step, whereas the protection layer removing step is executed after the ion etching step.
