  • Publication number: 20240175471
    Abstract: A clutch device includes an inner ring; an outer ring; a ratchet engagement mechanism; and a switching mechanism. When an engaging member is provided on an inner peripheral portion of the outer ring, a cam member includes a cam inner ring portion provided to rotate together with the inner ring, a cam outer ring portion disposed outside the cam inner ring portion, and a plurality of rolling elements disposed between the cam inner ring portion and the cam outer ring portion. When the engaging member is provided on an outer peripheral portion of the inner ring, the cam member includes a cam outer ring portion provided to rotate together with the outer ring, a cam inner ring portion disposed inside the cam outer ring portion, and a plurality of rolling elements disposed between the cam inner ring portion and the cam outer ring portion.

  • Publication number: 20040097644
    Abstract: A reaction product of (I) an aqueous emulsion of a copolymer of (a) 5-50 wt % of an ethylenically unsaturated carboxylic acid monomer and/or the salt thereof, (b) 0.05-20 wt % of ethylenically unsaturated sulfonic acid monomer and/or the salt thereof, and (c) other ethylenically unsaturated monomers polymerizable with the monomers (a) and (b), provided that the total of monomers (a), (b), and (c) is 100 wt %, the copolymer having a Tg from −30° C. to +20° C., and (II) a polyvalent metal compound. The reaction product is useful as a floor polish excelling in durability, adhesion to substrates, and recoatability that are well balanced with removability with an alkali, and decreased TVOC due to absence or low content of a low boiling point coalescent agent and plasticizer.

  • Publication number: 20030225203
    Abstract: The present invention provides a copolymer latex capable of remarkably improving the bond strength of coated paper, excelling in coated paper properties such as print gloss, and excelling in coating operability such as redispersibility, mechanical stability, and anti-stick properties, a process for producing the copolymer latex, and a paper coating composition. In the copolymer latex of the present invention, the content of components detected before an elution time at which a component having a polystyrene-reduced molecular weight of 1,000,000 is detected in a molecular-weight distribution measured by gel permeation chromatography (GPC) is 31% or more, the weight average molecular weight of components detected after the elution time at which the component having a polystyrene-reduced molecular weight of 1,000,000 is detected is 30,000-400,000, and the toluene insoluble content is 31 wt % or more.

  • Patent number: 5385975
    Abstract: Polymer particles including polysiloxane is disclosed. The polymer particles are prepared by condensing at least one organosilane or organosiloxane compound in the presence of organic polymer particles which are prepared from specific monomers and dispersed in an aqueous medium. The polymer particles possess excellent water resistance, weatherability, water repellency, adhesion, and flexing resistance, and thus are useful as water paints, coating agents, carpet packing material, floor polishing agents, cementing medium, and the like.

  • Patent number: 5235013
    Abstract: An oxygen-permeable polymer is prepared by polymerizing (1) at least one first monomer selected from the group consisting of alkenes of 6-10 carbon atoms having one double bond and one side chain methyl group, and (2) at least one second monomer selected from the group consisting of (fluoro)siloxanylalkyl mono(meth)acrylates, (fluoro)siloxanylalkyl di(meth)acrylates, fluoroalkyl (meth)acrylates, alkyl (meth)acrylates, .alpha.-alkyl- or .alpha.-fluoroalkyl-acrylic acids, alkyl .alpha.-alkylacrylates, alkyl .alpha.-fluoroalkylacrylates, fluoroalkylacrylates, fluoroalkyl .alpha.-fluoroalkylacrylates and fluoroalkyl .alpha.-ackylacrylates, the copolymerization proportions of the first monomer and the second monomer being such that the first monomer ranges from 5-80% by weight and the second monomer ranges from 20-95% by weight.

  • Patent number: 4323864
    Abstract: A binary transversal filter which has a plurality of stages of shift registers that are driven by timing signals of a frequency which is a multiple of that of clock pulses being introduced, and a weighting circuit which weights outputs of shift registers of each of the stages, so that outputs of the weighting circuit can be synthesized. The characteristic feature of the present invention resides in the facts that NRZ signals are introduced into the shift registers, and the shift registers are driven by timing signals of a frequency which is a multiple of that of clock pulses of the NRZ signals.
