摘要:
A flame retardant cloth, used for example in interiors as a material for curtains, comprises (A) 60-40 parts by weight of fiber which contains 8-70 wt. % of halogen chemically bonded to a polymer and 1-8 wt. % of Sb compound not chemically bonded to a polymer, and has a shirnkage factor at 240.degree. C. of not less than 40% under a load of 300 mg/metric count yarn count (17), and (B) 60-40 parts by weight of polyester fiber, which compounded making a total of 100 parts by weight. This cloth can retain its high fire retardance even after it has been subjected to a process using a binder, such as pigment printing, and enables the range of application of a compound flame retadant fiber product comprising polyester fiber and halogen-containing fiber to be further widened.
摘要:
Provided is a flame-retardant fabric comprising (A) from 16 to 45 parts by weight of a halogen-containing fiber containing from 11 to 67% by weight of a halogen chemically bound to a polymer and from 4 to 30% by weight of an Sb compound not chemically bound to a polymer, (B) from 10 to 36 parts by weight of a polyvinyl alcohol fiber, and (C) from 60 to 40 parts by weight of a polyester fiber, which are compounded to total 100 parts by weight. The flame-retardant fabric of the present invention has an excellent heat resistance, an excellent processability and a high flame retardance. This fabric can improve the feeling after high-temperature processing such as transfer printing and further widen the range of application of a polyester fiber product.
摘要:
A flame retardant union fabric obtained by combining (A) 30 to 70% by weight of a fiber comprising as a main component a flame retardant halogen-containing fiber made of a composition comprising 100 parts by weight of an acrylic copolymer of 30 to 70% by weight of acrylonitrile, 30 to 70% by weight of a halogen-containing vinyl monomer and 0 to 10% by weight of a vinyl monomer copolymerizable with them, 10 to 30 parts by weight of an antimony compound and 8 to 30 parts by weight of a zinc stannate compound, with (B) 70 to 30% by weight of a cellulosic fiber. The flame retardant union fabric shows a high flame resistance which passes the M1 class of NF P 92-503 burning test in France even after the post-treatment.

An image blur correction device 400 includes a pitching movement frame 405, a yawing movement frame 408, and a third group frame 462. The pitching movement frame 405 supports a third lens group G3 included in an optical system for performing image blur correction. The yawing movement frame 408 supports the pitching movement frame 405 to be movable in the pitching direction perpendicularly intersecting a second optical axis A2, within a plane perpendicularly intersecting the second optical axis A2. The third group frame 462 supports the yawing movement frame 408 to be movable in the yawing direction along an arc whose center is a rotational axis A3, within a plane perpendicularly intersecting the second optical axis A2.
摘要:
The present invention aims to provide an imaging device and a camera realizing simultaneously a high magnification zoom lens system and the miniaturization of the device. The imaging device (2) includes a first lens group (G1), a second group frame unit (42), a first group frame unit (41), a motor unit (32), a third lens group (G3), and a CCD unit (33). The first lens group (G1) takes in a light flux incident along a first optical axis (A1). The second group frame unit (42) bends the light flux incident along the first optical axis (A1) to a direction along a second optical axis (A2). The first group frame unit (41) retains the first lens group (G1), and moves the first lens group (G1) in the direction along the first optical axis (A1). The motor unit (32) drives the first group frame unit (41). The first group frame unit (41) includes a driving frame (51) movable in the direction along the first optical axis (A1), and a first group frame retaining the first lens group (G1) and able to move in the direction along the first optical axis (A1) with respect to the driving frame (51).

A magnetic recording and reproduction apparatus includes a main chassis having a rotatable head cylinder provided thereon; and a sub chassis on which a tape cassette is mountable. The sub chassis is movable with respect to the main chassis between a tape cassette mountable position and a tape pull-out completion position, and the tape cassette mountable position is a position at which the tape cassette is mountable on the sub chassis and the tape pull-out completion position is a position at which information recording to and information reproduction from the tape, which has been pulled out from the tape cassette and has been wound around the rotatable head cylinder, can be performed. A portion of the main chassis along a forward end thereof is cut out toward the rotatable head cylinder.
