Title: Piezoelectric element
Inventor: SUZUKI AKIRA
IPC: A61B1/00
Filed: 1988-12-23
Abstract: PURPOSE:To prevent a short circuit and to miniaturize a piezoelectric element by taking the interval between a reference electrode and an outside electrode largely by making the length of the reference electrode in the lateral direction thereof on the side of the fixed end of the piezoelectric element shorter than the length of electrostriction ceramics in the lateral direction thereof and forming a protruding part to the reference electrode in the longitudinal direction thereof. CONSTITUTION:One end part of a reference electrode 1 in the longitudinal direction thereof is notched on both sides thereof so as to leave the center thereof having a width narrower than that of each of electrostriction ceramics 2a, 2b to form a tongue like part 4 and the length containing the tongue part of the reference electrode in the longitudinal direction is made larger than that of each electrostriction ceramics. The electrostriction ceramics having outside electrodes 3a, 3b and the reference electrode are stacked and a conductive tape 5 composed of a resin, rubber or a metal is wound around one end part of an electrostriction element so as to surround said end part to bond and fix said ceramics and the reference electrode. Lead wires 6, 7 are respectively bonded to the above-mentioned conductive tape and tongue part. By this method, both outside electrodes are brought to a continuity state by the conductive tape but, since the reference electrode can hold a sufficient distance from the conductive tape, a short circuit or discharge can be prevented. Further, the piezoelectric element can be miniaturized.

Inventor: ASOU SHINJI
IPC: G21K5/04
Filed: 1994-12-02
Abstract: PURPOSE: To control the quantity of beam without installing a filament voltage adjusting means in a d.c. high voltage part. CONSTITUTION: A hollow core transformer 1 received in the inside of a pressure container has a primary coil 2, a dividing secondary coil 3 and a secondary coil 3h for filament and the secondary coil 3 is connected with a rectifying circuit 6 of a d.c, high voltage generating apparatus 7. Magnetic fluxes attributed to the primary coil cross the secondary coil 3h to be connected with a filament 8 and a filament voltage adjusting coil 2c which generates magnetic fluxes in the direction to cancel the former magnetic fluxes is installed in the primary side of the hollow core transformer. Filament voltage is adjusted by adjusting the voltage applied to the adjusting coil by a voltage adjusting apparatus, e.g. a sliding transformer 21 and thus necessary beam current is generated.  Even if acceleration voltage is increased or decreased by an adjustable a.c. electric power source 20, fluctuation of the voltage of the secondary coil for the filament is suppressed and consequently stable beam current is thus generated.
