摘要:
A process for producing a thin film of a fluoride comprising reacting a gaseous fluorinating agent and gas of a volatile organometallic compound in a gas phase in a reactor, wherein a plasma of the gaseous fluorinating agent obtained by activating the gaseous fluorinating agent by microwave under a condition of electron cyclotron resonance is used as a fluorine source, and the fluoride is deposited on a substrate by reacting the plasma of the gaseous fluorinating agent with the gas of a volatile organometallic compound at outside of an area of generation of the plasma. A thin film of a fluoride which contains very little impurities such as carbon, oxygen, and organic substances, and is highly pure, transparent, and consolidated is produced.

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.

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 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.
