Filed: 1986-05-30
Abstract: PURPOSE:To form a magnetic film of iron nitride having good magnetic characteristics and including a little impurity such as carbon without damaging a substrate by decomposing a reactive gas consisting of a gaseous compound including iron atoms and a gaseous compound including nitrogen atoms by means of the light energy of an ultraviolet area and utilizing a plasma of a reducible gas such as hydrogen to cause a reaction at low temperature for forming the film. CONSTITUTION:A laser beam emitted by a laser 28 decomposes iron pentacarbonyl and ammonium by photo reaction to form a film of iron nitride on a substrate 21. During this reaction, ions including carbon are produced as side reaction by decomposition of iron pentacarbonyl and by this reaction, carbon is mixed into the film of iron nitride. For preventing that, a hydrogen plasma is produced from the hydrogen supplied from a hydrogen inlet pipe 8 by a plasma generator 12 and this plasma is introduced into a reactor 18. This hydrogen plasma reacts with the ions including carbon which is obtained as a by-product by decomposition of iron pentacarbonyl, and inclusion of carbon in the formed film can be prevented.

IPC: F24C15/20
Filed: 1981-08-10
Abstract: PURPOSE:To enhance the oil trapping effect of a grease filter and keep the pressure loss through the filter low by a construction wherein the filter is retained by both a body and a front cover so as to turn freely, and when the ventilation fan for the oven is in use, the filter may be moved to a proper position. CONSTITUTION:An impeller 2 and an electric motor 9 to drive it are located within a body 1, and a front cover is retained by the upper part of the body 1 so that it may be opened and closed freely. In such a ventilation fan for a cooking oven, a grease filter 6 adapted to trap the oil contained by the smoke produced when cooking is performed is retained by a filter receiving portion 8 of the body 1 at one end thereof and by a slide portion 4 of the front cover 5 at the other end thereof so as to allow both ends to turn freely. Accordingly, as the cover 5 is opened, the upper end of the filter 6 will slide along the slide portion 4 and project forwardly, thereby securing a sufficient distance between the filter 6 and an air intake port 10. Thus, the air-stream drawn in by the fan will flow through the whole surface of the filter 6 so that an improved oil or grease trapping effect may be obtained and also the pressure loss through the filter 6 may be kept low.
