Title:
PARTICLE DISPERSING APPARATUS
Document Type and Number:
Japanese Patent JPH02109381
Kind Code:
A
Abstract:
PURPOSE:To stabilize quality by dropping particles in a radial pattern, and dipersing the particles in a single layer. CONSTITUTION:The specified amount of particles is measured in an automatic measuring machine 1 as required. The particles are supplied to a net 3 having a rotary device through a funnel 2 for constant-speed falling of particles. The net 3 is provided with a speed controller 4 which adjusts the number of rotation. The net 3 is fixed to the lower part of a ring 10. A second funnel 9 which receives the particles from the funnel 2 is provided at the upper part, and the entire body is rotated. It is desirable that the number of rotation is 50-200rpm and the opening of the net hole is 1.0-3.0 mm. The particles which are dispersed through the net 3 in a radial pattern and fall are dispersed into a single layer by way of multiple-stage sieves 5. A hood 6 is provided in order to prevent the splashing until the particles reach the sieves 5 from the net 3. The particles fall into binder at the bottom from the sieves 5 with an application-film forming and mounting jig 7. In this way, a large quantities of composite piezoelectric bodies and pyroelectric sheets having stable quality can be supplied.
