摘要： To provide a filter cover which has little electromagnetic effect on a dielectric resonator and is able to lengthen the life of a press mold without impairing isolation between transmission and reception. A VCO comprising a dielectric resonator, a high-frequency oscillator, a base, a cover, in which the distance between the surface of the cover facing the dielectric resonator and the surface of the base facing the dielectric resonator is half or below of the effective wave length of the oscillator frequency, and the cover has periodic projections facing the dielectric resonator which are a quarter of effective wave length of the oscillator frequency, wherein the nearest distance between the surface of the dielectric resonator facing the cover and the surface of the cover facing the dielectric resonator is a quarter or over of the effective wave length of the oscillator frequency.

摘要： A pressure sensor superior in pressure resistance and capable of covering from a low to high pressure range as a measuring range is to be provided. Plural pressure sensing sections for high and low pressures are formed on a silicon board, the pressure sensing sections each com ing an outer frame portion, a diaphragm portion, a strain gauge portion and an electrode portion. The silicon board side with the strain gauge portions formed thereon and an insulating substrate having electrode take-out portions are bonded together in such a manner that the strain gauge portions are hermetically sealed and that the electrode portions on the silicon board and the electrode take-out portions of the insulating substrate are electrically connected with each other, to constitute a pressure sensing unit. The pressure sensing unit, a low-melting glass and a stem are laminated together in such a manner that lead pins are electrically bonded by solder to the electrode portions of the silicon board through the electrode take-out portions of the insulating substrate. In this state, the low-melting glass is melted to bond the pressure sensing unit and the stem with each other.
