    摘要: An electric dust collector that does not need an exhaust fan or special equipment for preventing dust from flying off. An incinerator is formed on a building, and a smokestack is raised so that it is integrated with the wall of the incinerator. The smokestack is formed from metallic sheeting and lined with refractories. A beam is installed over the smokestack. The beam is electrically insulated using insulatores. A discharge electrode is suspended form the beam at the center of the smokestack. The discharge electrode has many needle-like discharge pins almost in its lower half part. The negative pole of a DC high-voltage power supply is connected with the discharge electrode, while the positive pole is grounded and connected with the metallic sheeting constituting the smokestack.

    摘要: A magnetic recording and/or reproducing device for recording information on a disc-like magnetic recording medium and/or reproducing the information from it, said magnetic recording and/or reproducing device having a pair of magnetic head members each composed of a magnetic head chip and a slide pad for slidably holding the disc-like magnetic recording medium at its both surfaces between the pair of magnetic head members under a predetermined contact pressure, wherein the slide pad is so disposed as to surround the magnetic head chip and the top portion of the magnetic head chip is so disposed as to protrude by a predetermined amount from a sliding contact surface between the slide pad and the disc-like magnetic recording medium. It makes possible by the magnetic recording and/or reproducing device of the above described type to obtain such a desirable state in which the disc-like magnetic recording medium can be steadily held in contact with the magnetic head chips, since the slide pads act primarily to minimize the warp of the disc-like magnetic recording medium and also the deformation of the disc-like magnetic recording medium which would result from a deviation in position of one or both of the magnetic head members relative to the disc-like magnetic recording medium.
