Claim 1
Independent Claim
105 words
THE COMBINATION COMPRISING A PIEZOELECTRIC CRYSTAL CONTROL ASSEMBLY, A SHEET OF HIGHLY THERMALLY CONDUCTIVE MATERIAL FORMING AN OUTER HOUSING OF SAID ASSEMBLY, A LAYER OF LOW DIFFUSIVITY MATERIAL SUBSTANTIALLY TOTALLY SURROUNDING AND ENGAGING THE OUTER SURFACE OF SAID SHEET, A SECOND SHEET OF HIGHLY THERMALLY CONDUCTIVE MATERIAL SURROUNDING AND ENGAGING THE OUTER SURFACE OF SAID LOW DIFFUSIVITY MATERIAL, A FILAMENT OF HIGH DIFFUSIVITY MATERIAL INTERCONNECTING SAID SHEETS, AND ELECTRICAL CONDUCTORS OF HIGH DIFFUSIVITY PASSING THROUGH SAID LAYER AND SHEETS, SAID ELECTRICAL CONDUCTORS AND SAID FILAMENT BEING OF A CONDUCTIVITY AD CROSS SECTION TO PROVIDE SUBSTANTIALLY THE SAME NET ATTENUATION TO HEAT FLOWE AS SAID LAYER.
