    摘要: In a magnetron device, a shield box is disposed covering a cathode stem and energizing power is supplied from the outside of the shield box to cathode lead terminals in the shield box.An energizing power supplying means comprises a transformer having a primary coil and a secondary coil which are both wound around a magnetic core and connect inductively the inner section of the shield box with the outer section. Thus high frequency noise which is a part of high frequency energy oscillated in anode resonant cavities and transmitted into the shield box through the cathode lead terminals is perfectly confined in the box. Therefore high frequency noise leaking out from the magnetron device toward a commercial power source is significantly reduced.

    摘要: A method for controlling an injurious insect is herein disclosed, which comprises disturbing the copulative communication of an injurious insect to prevent proliferation of the insect by distributing a source of the sex pheromone thereof over a field to be controlled to make the sex pheromone release from the source distributed in the field, wherein a source of the sex pheromone having a high effective component-release rate per unit time is distributed over the central region of the field at a low density while a source of the sex pheromone having a low effective component-release rate per unit time is distributed over the peripheral region of the field at a high density. A sex pheromone-release agent having an effective component-release rate ranging from 0.01 to 2 g/day may be distributed over the central region of the field at a density ranging from 1 to 50 locations/ha, while a sex pheromone-release rope having an effective component-release rate ranging from 5 to 250 mg/m/day may be substantially uniformly stretched around the peripheral region of the field at a density ranging from 10 to 150 m/ha.
