2 results about "Patch type" patented technology

The invention discloses a piezoelectric patch type detectoscope for deepwater soundwave detection. The detectoscope is characterized in that the length of an air cavity of an anti-pressure medium soundwave resonant cavity is half the soundwave operation wavelength lambda; a piezoelectric electric transducer is installed at one end of the anti-pressure medium soundwave resonant cavity; and a piezoelectric ceramic patch of the piezoelectric electric transducer attaches to the inner end face of the air cavity in the anti-pressure medium soundwave resonant cavity. The detectoscope can still realize detection of the soundwave signals even under high pressure in deepwater and, with such a simple structure, can not only maintain the high detection sensitivity of the traditional piezoelectric electric transducers but also overcome the defect that the traditional piezoelectric electric transducers can not detect the soundwaves in water. The equipment is simple in design, has small volume and low cost and is convenient to use. The detectoscope can be widely applied to deepwater pipelines, oil wells, deep sea and other soundwave detection systems under high pressure.

The invention discloses a patch type electromagnetic component which comprises a base, wherein a winding column is fixedly connected with the base; an electromagnetic head is fixedly connected with the top of the winding column; a pair of electrodes are fixedly adhered to the bottom of the base; a section of connecting line is arranged between the electrodes; the connecting line is wound at the periphery of the winding column in a spiral manner; the connecting line is a copper line the surface of which is provide with an insulating film; the surfaces of the electrodes are plated with a layer of gold. According to the patch type electromagnetic component, as the electromagnetic component is integrated on one main body with two welding electrodes, the spiral connecting line is arranged between the welding electrodes, and the line body is wound on an electromagnetic component body, the structure is simplified, and SMT large-scale production of the electromagnetic components is achieved due to adoption of the welding electrodes applicable to SMT assembling.
