Abstract: PURPOSE:To provide a high frequency heating device which reduces unevenness in heating and increases efficiency, by a method wherein at least one wall surface of wall surfaces with which to form a heating chamber is caused to perform pendulum motion within some angle around an axis on the wall surface. CONSTITUTION:Microwaves radiated from a radiation antenna 2 of a magnetron 1 are transmitted through a waveguide 3 and are radiated in a hating chamber 5 through a coupling hole 4. Torque is transmitted from a drive part 15 to a shaft 16, by passage of it through a conversion part 17, a side wall 13 is driven. Since a side wall 13 is locked by means of a hinge 14, the side wall performs pendulum motion within a range of some angle to change the inclination angle of the side wall. Microwaves radiated in the heating chamber 5 is repeatedly reflected by an inner wall, but since the side wall 13 changes an inclination angle, the microwaves are prevented from repetition of reflection by the same wall surfaces therebetween. As a result, the microwaves are diffused to bring a food 9 into approximately an uniform heated state.

Filed: 1991-09-25
Abstract: PURPOSE:To facilitate the control of a diffusion depth in the impurity diffusion process for making a current passage area in a current checking layer in an light emitting element which has current narrowing structure.
