  • Publication number: 20240158662
    Abstract: A two-component curable coating agent capable of forming a surface protective layer having excellent weather resistance, acid resistance, fouling resistance, and elongation properties, and a multilayer film including a surface protective layer that is a cured film of the two-component curable coating agent. The two-component curable coating agent includes a main agent that contains a polyol containing an epoxy polyol (P) and an acrylic polyol (A), and a curing agent that contains a polyisocyanate, the epoxy polyol (P) being a reaction product of an epoxy group-containing compound (e) and a carboxyl group-containing compound (c). Furthermore, the multilayer film includes a substrate layer; a surface protective layer that is layered on and integrated with a first surface of the substrate layer and that is a cured film of the two-component curable coating agent; and an adhesive layer that is layered on and integrated with a second surface of the substrate layer.

  • Publication number: 20240150607
    Abstract: Provided are a two-component curable coating agent capable of forming a surface protective layer having excellent weather resistance, acid resistance, fouling resistance, and elongation properties, and a multilayer film including a surface protective layer that is a cured film of the two-component curable coating agent. The two-component curable coating agent of the present invention includes: a main agent that contains a polyol containing an acrylic polyol having an alicyclic structure and a hydroxyl value of 36 mgKOH/g or more and 125 mgKOH/g or less, and an alkyl polyol; and a curing agent that contains a polyisocyanate. The multilayer film of the present invention includes: a substrate layer; and a surface protective layer that is integrally layered on a first surface of the substrate layer and is a cured film of the two-component curable coating agent.

  • Patent number: 7734165
    Abstract: When focus adjustment operation is performed, a first measured distance acquired by utilization of TTL-AF and a second measured value acquired by utilization of a distance between the eyes have been computed in advance. The degree of reliability of the first measured distance is compared the degree of reliability of the second measured distance in accordance with a result of a determination as to whether or not a face is detected, a result of a determination as to whether or not an ambient brightness value Br is equal to or less than a reference value, a result of a determination as to whether or not a focal length “f” is equal to or less than a reference value, and a result of a determination as to whether or not a second measured distance De is less than a first measured distance Dt.

  • Publication number: 20080050108
    Abstract: The accuracy of focus adjustment operation is enhanced further. When focus adjustment operation is performed, a first measured distance acquired by utilization of TTL-AF and a second measured value acquired by utilization of a distance between the eyes have been computed in advance. The degree of reliability of the first measured distance is compared the degree of reliability of the second measured distance in accordance with a result of a determination as to whether or not a face is detected (S10), a result of a determination as to whether or not an ambient brightness value Br is equal to or less than a reference value (S12), a result of a determination as to whether or not a focal length “f” is equal to or less than a reference value (S16), and a result of a determination as to whether or not a second measured distance De is less than a first measured distance Dt (S18). Focus adjustment operation is performed in accordance with a measured distance determined to be more reliable.

  • Patent number: 4424834
    Abstract: An elastic shaped article of a laminated construction of at least two layers, comprising (a) a layer of a soft polyvinyl chloride combining polyvinyl chloride with a plasticizer and (b) a layer of at least one thermoplastic elastomer selected from the group consisting of polyester type elastomers, polyurethane type elastomers, and polyamide type elastomers is useful for production of boots, ducts, hoses, tubes, sealing members, covering members, etc. in various transportation machines, construction machines, industrial machines, machine tools, etc. The elastic shaped article whose component layers are particularly laminated by co-extrusion is molded by the blow molding method. When the plasticizer which is combined with polyvinyl chloride to form the soft polyvinyl chloride has an average molecular weight of at least 700, the produced elastic shaped article excels particularly in oil resistance at elevated temperatures.
