摘要： PURPOSE: To make it possible to obtain various characteristics with a bimorph plate of the same shape. CONSTITUTION: The bimorph plate 1 consists of two sheets of piezoelectric ceramics 11, 12, an intermediate electrode 13 and external electrodes 14, 15. The surfaces of the external electrodes 14, 15 of such bimorph plate 1 are provided respectively with vibration adjusting plates 16, 17. The adjustment of a resonance frequency is executed by the bimorph plate 1 of the same shape by changing the width of these vibration adjusting plates 16, 17. Further, one end of such bimorph plate 1 is fixed within, for example, a rotary drum by fixing parts 2, 3 and the other end is provided with a head chip 5 via a holder 4. Displacement is applied on the piezoelectric ceramics 11, 12 and the height of the head chip 5 is changed when the prescribed voltage is impressed between the intermediate electrode 13 and the external electrodes 14, 15.

摘要： PROBLEM TO BE SOLVED: To prevent a reproducing signal from being adversely affected even when the vertex of a magnetic tape sliding surface is shifted from a track width center to lower or upper side because of variance in machining or the like. SOLUTION: The thin film magnetic head 10 is provided with a magnetic core 13 having core half bodies 11 and 12 joined to each other in the longitudinal direction, the core half bodies 11 and 12 being composed of cores 11c, 11d, 12c and 12d stuck to upper and lower sides to sandwich metallic magnetic films 11b and 12b, a magnetic tape sliding surface 14 formed in the end surface of one side of the magnetic core, a magnetic gap 15 and a coil wound through a winding wire window around the core half bodies. The widths H1 and H2 of the upper and lower cores of the half bodies are different from each other.

摘要： PROBLEM TO BE SOLVED: To obtain excellent electromagnetic conversion characteristics while controlling optimum tracking by joining members with a UV curing resin while each member is maintained in an optimum state. SOLUTION: Fitrs, a bimorph plate 3 is joined with a parallel leaf spring 7. Then the UV curing resin 8 is applied on the interface between the bimorph plate 3 and the leaf spring 7. The UV curing resin 8 has 1.2 to 1.6MPa Young's modules so that it does not give strong tension to each member untill the resin is cured. Therefore, by using the UV curing resin 8 as an adhesive to join the members, the members can be joined without changing the position of each member. The bimorph plate 3 and the leaf spring 7 coated with the UV curing resin 8 are put in a UV curing furnace and irradiated with UV rays.

摘要： PURPOSE:To control quantity of bending displacement of a piezoelectric plate and to adjust a video head by controlling driving voltage impressed to the upper end fixed part of a conductive holder holding a base end part of a bimorph plate between them, the lower end fixed part and an intermediate electrode. CONSTITUTION:A bimorph plate 10 is an electromechanical conversion device in which two piezoelectric plates 6, 8 are stuck together with adhesive of an epoxy resin group by holding an intermediate electrode 7 between them, surface electrodes 5, 9 are formed by electrode materials from the fixed end to a free end on the piezoelectric plate 6, 8. A base end part 10b being the fixed end of the bimorph plate 10 is held between the upper end fixed part 14a of a conductive holder 14 and the lower end fixed part 14b. Fixed parts 14a, 14b of the upper end and the lower end are formed by conductive materials so as to be conductive to the surface electrodes 5, 9. Two piezoelectric plates 6, 8 stuck together are bent and shifted by impressing driving voltage to the base end parts of the surface electrodes 5, 9 and an intermediate electrode 7 and extending or contracting each piezoelectric plate 6, 8 in the reverse direction each other for the direction of extension and contraction.
