Abstract: PURPOSE: An automatic honeybee separation device for bee keeping is provided to enhance work efficiency by reducing time and labor. CONSTITUTION: An automatic honeybee separation device for bee keeping comprises a base(10), a main frame(20), a supporting part(30), and a brush part. In the base, a plurality of grips is installed at a constant interval so that a user can grip a comb. The main frame forms a space so that the base can be placed inside. The supporting part is installed in the main frame to be reciprocated. The brush part is installed to be ascended and descended in the upper part of the base.

Abstract: n electrostriction ceramics is composed of the powder mixture including lead oxide, niobium oxide, titanium oxide (titania), barium carbonate, zinc oxide, and 0.4 wt.% yttrium oxide (yttria) as an additive. The electrostrictive strain ceramics for a microdisplacement device has the general formula of 0.85Pb(Zn1/3Nb2/3)O3- 0.10BaTiO3-0.05PbTiO3. The additive increases the density of the electrostriction ceramic body and the permittivity by generating the space charge polarization between grain boundary layers.
