Patent KR-860001519-B1 (KR)
Title: Method of producing magnetron and apparatus therefor
Inventor: MURAGAMI HIROYA
IPC: H01J9/24
Filed: 1981-10-21
Granted: 1986-09-30
Abstract: In producing a magnetron having a spiral fin wound on a magnetron body and attached to it, the fin is wound on the magnetron body as soon as it is produced, and a leading end and a trailing end of the fin are fixed to the magnetron body. This increases the number of turns of the fin wound on the magnetron body and improves the bond strength with which the fin is bonded to the magnetron body, to increase the effect achieved by the fin in dissipating heat and to avoid a decline in the performance characteristics of the magnetron. This is conducive to increased productivity of the magnetron.

Abstract: The   apparatus   using   contact   material   horizontally reciprocated, performs biological treatment of  waste  water.  The apparatus comprises a treatment tank (10) for storing  wastewater, contact material (20) submerged in the  wastewater,  support  body (30) for supporting the material  (20),  driving  means  (40)  for horizontally reciprocating the body (30). The  apparatus  prevents thickening of biological surface layer attached  on  the  material (20) by controlling reciprocating velocity of the means (40).
