  • Patent number: 9707765
    Abstract: What is disclosed is an apparatus and method for inhibiting the formation of sediment in an ink tank of a MICR inkjet printer. In one embodiment, the present apparatus comprises an ink tank containing MICR ink and an electromagnet which resides in a chamber located on, near, or inside the ink tank. Activation of the electromagnet causes the particles to be attracted to the electromagnet's magnetic field such that the particles are lifted off a bottom of the tank to inhibit sediment formation thereon. The electromagnet can be activated in response to the MICR inkjet printer having been turned OFF. A sensor may further be employed to activate the electromagnet in response to one of: sediment in the ink tank having reached a pre-determined level; a flow-rate of liquid ink through the tank having fallen below a threshold level, sediment levels, or a pressure inside the tank.

  • Patent number: 7144442
    Abstract: A degassing device capable of regulating an amount of air dissolved in a liquid. A device for measuring amounts of dissolved oxygen measures the amount of oxygen dissolved in one of a coating liquid which has yet to be degassed, and is to be fed to a film degassing device, and a coating liquid which has been degassed and discharged from the film degassing device. Based on measured results, a control unit regulates the degree of opening of a vacuum valve so as to change the degree of degassing performed by the film degassing device, thereby suppressing fluctuations in an amount of oxygen dissolved in the coating liquid. A load never constantly acts on the film all the time, the film life can accordingly be extended, thus resulting in reductions in running costs.

  • Patent number: 6923865
    Abstract: Techniques for precisely controlling the size of particles in a coating solution delivered to a coating apparatus involve continuous classification of coating particle size using a tangential flow filter assembly. The techniques may be particularly useful in the preparation of coating dispersions for manufacture of magnetic recording media. A classification technique makes use of a tangential flow filter assembly that permits delivery of coating particles below a maximum size threshold to a coating path. The filter assembly may be disposed in a circulation path that includes one or more processing devices to reduce the size of coating particles carried by a coating solution. The filter assembly enables coating particles above the maximum size threshold to be recirculated through the circulation path and subjected to repeated processing to reduce particle size to a desired size range.

  • Patent number: 6884281
    Abstract: First, the overall quantity of bubbles in a coating liquid is reduced in advance by vacuum deaeration performed in conjunction with preparation of the coating liquid in a stirring tank in a first step, then bubbles of relatively large sizes, of bubbles that have not been removed in the first step are removed by a tank type deaeration device with ultrasonic waves in a floatation tank in a second step, and finally bubbles of very small to small sizes that are difficult to remove in the first and second steps are dissolved in the liquid under pressure with ultrasonic waves and thereby removed in a pipeline in a third step. According to this, bubbles in the coating liquid can reliably be removed irrespective of the nature of the coating liquid, a large amount of coating liquid can be treated, and the possibility that the quality of the deaerated coating liquid is adversely affected is eliminated.
