Filed: 1987-05-29
Abstract: PURPOSE:To produce a composite piezoelectric body in a single process for improve the production efficiency, by shaping a material for the piezoelectric body into a sheet form while simultaneously thermocompression bonding conductive sheets integrally to the both faces of the sheet form material. CONSTITUTION:A piezoelectric body material 10 is carried on rolls 11 through a pair of conductive sheets 12. The rolls 11 are rotated in opposite directions while the material 10 is drawn between the rolls 11 through the sheets 12, whereby the material is extended and shaped under compression and heating by the rolls. Thus, the sheets 12 and the material 10 are compressed and heated by the rolls 11 simultaneously. Accordingly, the sheets 12 are thermocompression bonded integrally to the both faces of the extended material 10 to provide electrodes for a composite piezoelectric sheet. In this manner, a composite piezoelectric body can be produced in a single process and, therefore, the production efficiency can be improved remarkably.

IPC: G11B5/127
Filed: 1986-06-12
Abstract: PURPOSE:To reduce the product cost by constituting a slot setting a track width of a magnetic head as a cross sectional shape coincident with the circumferential shape of a rotary grinder used for grinding thereby reducing the time required for the movement of the rotary grinder at slot processing.
