  • Patent number: 10844176
    Abstract: The use of an N-acylaminoacid condensate as a surfactant in the preparation of silicone rubber particle emulsions allows the emulsions to be prepared with exceptionally low levels of surfactants. The resulting rubber particles display typical silicone rubber characteristics in contrast to rubber particles prepared using larger amounts of conventional surfactants.

  • Publication number: 20200261334
    Abstract: Aqueous dispersions which exhibit properties required of an aqueous dispersion and achieve stability and homogeneity include inorganic particle groups dispersed in an aggregation state in water. In this dispersion, when the total mole number ratio represented by moles of surface hydrophilic groups of the inorganic particle groups moles of surface hydrophobic groups is within a prescribed lower limit value or more depending on the aggregating properties of inorganic particles, the inorganic particle groups contain self-micelle-like aggregates and hydrophobic-rich aggregates.

  • Patent number: 10173296
    Abstract: A grinding machine includes a rotatable spindle having a lower end to which a grindstone for grinding a wafer is attached; linear guides supporting the spindle slidably to a column; a spindle feeding mechanism feeding the spindle in a vertical direction; and constant-pressure feeding mechanism interposed between the spindle feeding mechanism and the column and suspending the spindle feeding mechanism. The constant-pressure feeding mechanism raises the spindle feeding mechanism in the vertical direction when a friction force acting on the grindstone is higher than a predetermined value.

  • Publication number: 20090225955
    Abstract: The angle of each collimator plate with respect to an X-ray focal point is determined by fitting the collimator plate in grooves formed in upper and lower supports each having an integral structure. In addition, the warpage of each collimator plate is corrected and its flatness is maintained by fitting the periphery of the collimator plate which is on the X-ray detector side in a corresponding groove of an abutment plate provided on the X-ray detection surface side of the upper and lower supports. Furthermore, each collimator plate is supported by the corresponding grooves of the upper and lower supports and the corresponding groove of the abutment plate at least three sides.

  • Patent number: 6341906
    Abstract: A tape cassette is set in a cassette accommodating section of a tape printer. A magnetically affixable printing tape is fed out from a holding reel along with an ink ribbon having a non-magnetic ink layer formed thereon across a cut in the tape cassette and conveyed through between a thermal head and a platen roller while being pressed by those elements. The printing tape comprises a printing layer and a magnetic layer pasted to the printing layer. The magnetic layer is magnetized such that S and N poles are alternately arranged longitudinally of the tape to thereby prevent turns of the tape roll from shifting widthwise. The magnetic layer has a coated fluorine layer formed thereon or has wrinkles formed thereon to thereby prevent blocking from occurring on a printing face of the tape due to its winding. Thus, the printing tape is conveyed in a correct attitude to enable a high quality image to be printed thereon.
