Abstract: PURPOSE:To provide a photoswitch of the construction permitting extremely easy mounting to a monolithic configuration photointegrated circuit by disposing plural Schottky electrodes so that the end parts of plural optical guides may be formed at the end part of one optical guide. CONSTITUTION:Now, when a change-over switch 12 is selecting an optical guide 8, the light 14 entering from the terminal of an optical guide 7 arrives at a branch 10  by propagating in the n-GaAs layer encircled by a semi-insulation characteristic  GaAs substrate and the depletion layer under a Pd Schottky electrode. Here, the optical guide 8 is in the state that it can function as an optical guide because the depletion layer under the Pd schottky electrode has arrived on the surface of the semi-insulation-characteristic GaAs substrate, but the optical guide 9 does not function as  an optical guide because the depletion layer under the Pd Schottky electrode has not  arrived at the surface of the semi-insulation-characteristic substrate. Hence, the  light having propagated in the optical guide 7 is introduced into the optical guide 8  in the branch 10 and is radiated 15 from the terminal thereof.

Title: Production of powder by centrifugal atomization
Inventor: OKOCHI TAKAO
IPC: B01J2/14
Filed: 1990-06-29
Abstract: PURPOSE:To efficiently produce powder of desired particle size by rendering a temp. distribution to the top of a rotating body for atomizing a melt so that a temp. above the m.p. of the melt at the central part of the rotating body is reduced to a temp. below the m.p. at the peripheral part and feeding the melt. CONSTITUTION:When a melt is fed to the top 11a of a rotating body 11, this rotating body 11 deprives the melt of its heat and a thin solid layer is formed. At the time when the quantity of heat supplied by the melt is balanced with the quantity of heat absorbed by the rotating body 11, the growth of the solid terminates and the melt fed is dispersed and scattered on the solid layer by centrifugal force. The moment the centrifugal force exceeds the surface tension of the melt, the scattering of the melt is caused. A refrigerant passage 12 is formed at the inside of the peripheral part of the rotating body 11 so that the peripheral part is kept at a temp. below the m.p. of the melt. The melt is allowed to flow on the rotating body 11 and atomized by centrifugal force. The particle size of the resulting powder is small and the particle size distribution is narrowed because the scattering position of the melt is controlled.
