Title: Bonded ferrite
IPC: H01F1/34
Filed: 1992-03-12
Abstract: PURPOSE:To realize a flat junction interface between an Mn-Zn ferrite single crystal and an Mn-Zn ferrite polycrystal by a method wherein a ZrO2 oxide layer is arranged between the single crystal and the polycrystal as an intermediate layer. CONSTITUTION:Respective flat plates consisting of an Mn-Zn ferrite polycrystal 2 and an Mn-Zn ferrite single crystal 1 are machined and the junction surface between the flat plates is subjected to mirror-like finish. After that, a ZrO2 layer is formed on the junction surface of the Mn-Zn ferrite sputtered single crystal 1 having a thickness of 250nm by a magnetron sputtering device. A surface 3 formed with the ZrO2 layer is brought into contact with the junction surface of the polycrystal 2 and while a pressure is applied, a heat treatment is performed under an N2 atmosphere to obtain a bonded ferrite. Thereby, the junction interface of the polycrystal 2 with the single crystal 1 can be controlled very flatly without deteriorating the magnetic characteristics of the bonded ferrite. As a result, a magnetic head to which the bonded ferrite is adopted can be reduced in rotational noise and can be lessened in variation in its performance.

Title: Cylinder liner
Inventor: DEGAWA TAKU
IPC: F16J10/04
Filed: 1979-07-13
Abstract: PURPOSE: To make a cylinder liner tighter and finishing easier, even if the temperature rises inside the cylinder, which are used for light steel-made cylinder body by providing projections along the longitudinal direction on the outer periphery of the cylinder liner.  
     CONSTITUTION: When a cylinder liner 11 is fitted into a cylinder body 5 under pressure, outer periphery projections 12 of the liner base plate 11a are firmly fitted into the inner shell of the cylinder body 5. If a temperature rises inside the cylinder during operation, they should become loose due to thermal expansion rates of the cylinder body 5 and cylinder liner 11. However, the projections 12 are firmly built-in on the inner shell of the cylinder body 5, which prevents them from turning loose. Since each projection 12 forms a part of the cylinder liner, axial movements of the cylinder liner 11 are restricted by an end surface 12a of each projection 12. Therefore, the inner shell of the cylinder body 5 is capable of being straight finished with increased accuracy.
