  • Patent number: 11185001
    Abstract: A component placing device to place a component on a board, including: a shaft having a lower portion and an upper portion; a component holder that is attached to the lower portion of the shaft in a state of being vertically displaceable and has a suction hole for holding the component by a negative pressure; an elastic body that biases the component holder downward with respect to the shaft; a servo motor that raises and lowers the shaft; and a controller that sets a thrust limit value for limiting a thrust of the servo motor and limits the thrust of the servo motor to be equal to or lower than the thrust limit value when the component holder is lowered toward the board. The thrust limit value is set within a range in which a load is smaller than a force by which the elastic body biases the component holder.

  • Publication number: 20100092432
    Abstract: [Problems] To provide a novel use of multipotential stem cells originating in a fat tissue. [Means for Solving Problems] It is intended to provide a cell preparation which contains multipotential stem cells originating in a fat tissue and is usable for an ischemic disease, impairment of renal function, wound, urinary incontinence or osteoporosis. As the multipotential stem cells originating in a fat tissue, use is made of cells which proliferate in the case of centrifuging cells separated from a fat tissue and culturing the thus sedimented cells (an SVF fraction) under low-serum conditions. In an embodiment, a cell preparation containing the SVF fraction is provided.
