Title: Piezoelectric transformer and its manufacture
Inventor: TOYODA JUNICHI
IPC: H01L41/107
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To secure the creeping distance between primary- and secondary-side external electrodes in a piezoelectric transformer and, at the same time, to reduce the size of the transformer and improve the efficiency of the transformer. SOLUTION: A piezoelectric transformer is manufactured in such a way that a plurality of elements 11 each of which is formed by integrally baking a green sheet composed of a piezoelectric material, such as the PZT, etc., and an internal electrode is laminated upon another in the longitudinal direction and the elements 11 are thermocompression bonded to each other. Input-side electrodes 12a and 12b and output- side external electrodes 12c and 12d for connecting the internal electrodes of the laminated elements 11 in parallel with each other are formed of the same electrode paste as that used for forming internal electrodes.  Then insulators 13a and 13b composed of the PZT, etc., are formed on the section between the adjacent external electrodes 12a and 12c and the half surfaces of the electrodes 12a and 12c and the section between the adjacent electrodes 12b and 12d and the half surfaces of the electrodes 12b and 12d by thermocompression bonding, printing, or coating. Since the sections between the external electrodes 12a and 12c and between the external electrodes 12b and 12d are coated with the insulators 13a and 13b, each creeping distance becomes infinite and the transformer functions as a superior insulating transformer.

IPC: G11B17/028
Filed: 1990-10-02
Abstract: PURPOSE:To prevent deviation in the direction of a rotation angle even if a distance between a driving pin and a rotation shaft changes by moving the driving pin in the direction of the rotation shaft in a magnetic recording medium driving hole. CONSTITUTION:The driving pin 1 is fixed to the tip of the arm 2 and the tip of the arm is held by a supporting pin 3b engaged with a guide groove 4b, whereby it is pressed in the direction of a pedestal 5 by a force spring 6. The guide groove 4a is provided at the center of the arm 2 and a supporting pin 3a fitted to the pedestal 5 is engaged with the groove. Thus, the arm 2 can be moved in an open/close direction as against the pedestal with the supporting pin 3b as a fulcrum and with the supporting pin 3a as a guide. A return spring 7 operates in such a way that a magnetic recording medium is turned in a direction opposite to the rotary direction of the medium. Thus, the driving pin 1 can be moved to the direction of the rotation shaft 8 in the magnetic recording medium driving hole 11 even if the distance between the driving pin 1 and the rotation shaft 8 changes and therefore deviation in the direction of the rotation angle is prevented.
