  • Patent number: 10668593
    Abstract: The polishing head comprises: a head main body part; a carrier being connected to the head main body part; a pressure chamber; a fluid supplying section; a linear motion guide having an outer cylindrical body and a spline shaft, which is provided in the outer cylindrical body and capable of moving in an axial direction thereof, and which is prohibited to rotate with respect to the outer cylindrical body so as to transmit a rotational force to the spline shaft through the outer cylindrical body; and a rotation transmitting plate being provided between a lower end of the spline shaft and an upper face of the carrier, the rotation transmitting plate being capable of tiltably supporting the carrier and transmitting a rotational force of the spline shaft to the carrier.

  • Patent number: 10632590
    Abstract: The work processing apparatus of the present invention comprises: a processing section for processing or treating a work; and a liquid chemical supplying section for supplying a liquid chemical to the processing section. The liquid chemical supplying section includes: a plurality of liquid chemical bags for storing the liquid chemical; a bag holding part in which the liquid chemical bags are attached and held; and a liquid feeding part, to which the liquid chemical bags are detachably connected, for feeding the liquid chemical from the liquid chemical bags to the processing section. Each of the liquid chemical bags is produced by overlapping flexible resin sheets with each other and welding their edge parts to form into a bag. Each of the liquid chemical bags has a port part communicating with an outside. A joint with a valve is attached to each of the port parts.

  • Patent number: 5840705
    Abstract: This invention relates an .alpha.-glucosidase inhibitor mildly inhibiting .alpha.-glucosidase locally present in the micro-villus of small intestine, a composition principally comprising sugar and containing the inhibitor, a food, a sweetener and a feed. The inhibitor delays the digestion of starch, starch-derived oligosaccharides and sucrose, so that the inhibitor has an action of suppressing rapid increase in blood glucose level and an action of suppressing insulin secretion at a lower level. Thus, the inhibitor is useful for the prophylaxis of obesity and diabetes mellitus. The .alpha.-glucosidase inhibitor of the present invention is composed of nucleotide, nucleoside, or base as the structural component of nucleic acid and one or two or more digestible sugars selected from sucrose, starch and starch-derived oligosaccharide. The .alpha.-glucosidase inhibitor mildly inhibits the action of .alpha.

  • Patent number: 5463038
    Abstract: The present invention relates to crystals of 1-kestose which is a fructooligosaccharide, and it is an object of the present invention to provide high-purity 1-kestose crystals having no hygroscopicity and a method of producing the crystals. Methanol is added to an aqueous solution containing as a main ingredient 1-kestose with a purity of 80% or more, and the mixture is then dried. Methanol is further added to the mixture to obtain 1-kestose crystals with a purity of 90% or more. An aqueous solution with a purity of 70% or more is concentrated, and 1-kestose microcrystals are added to the concentrate obtained to separate 1-kestose crystals with a purity of 94 to 99.9%.
