Title: Magnetron
Inventor: KUSUKI SHIGERU
IPC: H01J23/15
Filed: 1984-06-14
Abstract: PURPOSE:To suppress high harmonic radiation by providing a wave absorber made of compound ferrite inside a heater box. CONSTITUTION:A ceramic material 15 is provided in a heater box space 14 while compound ferrite plates 19 and 20 are provided along the heater box 9. A compound ferrite plate is a material made of a mixture of a high heat-proof delivative such as polyethylene chloride rubber, silicon rubber and polyesther with ferrite powder while having a wave absorbing function of converting wave energy into thermal energy. By using a compound ferrite material having higher resonance frequency of wave absorption than fundamental frequency of a magnetron, a component lower than a fundamental wave of waves from a wave interaction space can be prevented from leaking outside by an L-C filter or the like while a high harmonic component can be prevented from leaking outside by a wave absorber.

Abstract: PROBLEM TO BE SOLVED: To protect a human body by using a circuit for suppressing the radiation of a magnetic field and electromagnetic waves generated from an electric space heater in contact with the body such as an electric blanket, an electric carpet or the like. SOLUTION: In order to suppress electromagnetic waves and a magnetic field radiated from the heat generating circuit of an electric blanket or an electric carpet, eliminate an influence to environment and protect a human body, the conductor 7 of the heater of an electric space heating device is folded and the two heater conductors 7 are made to come near to each other so that the directions of current flowing therethrough are opposite to each other.

Abstract: PURPOSE:To obtain acetylene black of good quality, by feeding acetylene gas while giving swirling stream to the gas, feeding hydrogen gas in the same direction as the swirling direction and keeping the temp. of the heat decomposition region of acetylene at a specified temp. CONSTITUTION:Raw material acetylene is introduced from the top of a furnace 1 through an acetylene supply nozzle 2 into the furnace where acetylene is heat- decomposed to form acetylene black and hydrogen gas.

However, in order to obtain acetylene black which has a good quality, a bulky structure and excellent electrical resistance, it is necessary to keep the temp. of a heat decomposition region at 1,800-2,100 deg.C. When the temp. of the formation of acetylene black is uniformized or adjusted, swirling stream gives acetylene gas and hydrogen gas is fed from a hydrogen gas introducing port 4 to the region 3 in the same direction as the swirling direction, whereby acetylene gas produces acetylene black in a uniformized turbulent flow.
