  • Patent number: 5825036
    Abstract: A weak electromagnetic wave radiation method and device are employed to generate weak electromagnetic waves and to radiate a subject with the weak electromagnetic waves, thereby enabling essential function recovery or activation in the subject being radiated. A weak magnetic field is generated, and is passed through an ultra-small weak electromagnetic wave radiating material to produce the weak electromagnetic waves, and the subject is then radiated with the weak electromagnetic waves. Subjects which benefit from the disclosed method and device include human tissue, plants, vegetables, foodstuffs, water and textile products.

  • Patent number: 4977012
    Abstract: A blank material for use as a ceramic wiring substrate of this invention is prepared by laminating a copper foil onto a ceramic base formed from a boron nitride sintered body or the like via a bonding layer interposed therebetween, and incoporating an inorganic filler in at least the ceramic base-containing side of the bonding layer.A fine and high density circuit substrate can be easily formed from the ceramic wiring substrate blank material according to the present invention by a conventional etching method.

  • Patent number: 4229157
    Abstract: A conduit for feeding a combustible waste gas to a ground flare is divided into a plurality of branch pipes each connected to burners of the ground flare. A stop valve is mounted on each of the branch pipes except the first pipe and provided with a limit switch for detecting the closing of the valve. A pressure detector is mounted on each of the branch pipes except the last pipe. The valve on each branch pipe opens in response to an opening signal from the pressure detector on the preceding branch pipe and closes in response to both a closing signal from that pressure detector and a signal from the limit switch on the valve on the following branch pipe, whereby the number of branch pipes used for feeding the waste gas is controlled in accordance with variations in the feed of waste gas.
