Patent number: 8312588Abstract: A window-screen-cleaning fabric comprises a base cloth and a plurality of fibers comprising (A) a crimped fiber and (B) a flat fiber. In the fabric, the crimped fibers and the flat fibers are raised from a first surface of the base cloth, and the height of the flat fibers from the first surface of the base cloth is greater than that of the crimped fibers from the first surface of the base cloth.Type: GrantFiled: March 16, 2009Date of Patent: November 20, 2012Assignees: Maru-T Ohtsuka Corp., Linzer Products Corp.Inventors: Tosirou Yamaguchi, Toshikazu Ohyama

Publication number: 20070056132Abstract: A paint roller comprises a liquid-impermeable tubular core member 6 with an engaging element 9 having a male structure of a separable fastener and a height of 0.3 to 4.0 mm on a surface thereof, and a cover member 8 with a female structure and a loop on the inner surface capable of male-female engaging with the engaging element on the surface of the core member. The density of the engaging element on the surface of the core member is 30 to 150/cm2. Thus, in such paint roller, when the cover member becomes dirty, damaged, or worn, the cover member can be exchanged to a new cover member. Such that, a roller body is repeatedly usable, and the paint roller can provide a good painted surface. Moreover, there is also provided an effect roller in which a painting pattern can be changed optionally.Type: ApplicationFiled: October 5, 2004Publication date: March 15, 2007Applicants: Kuraray Co., Ltd., MARU-T OHTSUKA CORP.Inventors: Tosirou Yamaguchi, Toshikazu Ohyama

Publication number: 20030213083Abstract: Provided is an inexpensive roller brush for painting, which has good paint holdability and good paint releasability and of which the brush face is smooth and homogeneous. Using the roller brush, the painted face is good and its quality is high. The roller brush is fabricated by covering a paint-impervious roll core with a paint holder of a fibrous circular material that contains conjugate fibers comprising a high-melting-point polymer component A and a low-melting-point polymer component B. In this, the fibrous circular material contains thermal-fusing conjugate fibers and at least a part of the fibers are fused to form a porous structure.Type: ApplicationFiled: May 16, 2003Publication date: November 20, 2003Applicant: KURARAY CO. LTD,Inventor: Tosirou Yamaguchi
