摘要:
Provided is a lightweight heat ray shield cover, such as a heat insulator, which has a three-dimensional shape and excellent shielding characteristics. The heat ray shield cover is a cover which is disposed near a heat source (26) such as an engine exhaust pipe and blocks the heat ray from the heat source, the cover being formed of a shaped composite in which aluminum alloy plates (2a, 2b) are layered on both the surfaces of a core foam resin (3b), respectively. The surface of one (2a) of the aluminum alloy plates in the shaped composite is provided to face the heat source (26).

The invention provides a natural fiber-reinforced thermoplastic resin injection molding having an excellent ability to discharge static electricity. The natural fiber-reinforced thermoplastic resin injection molding is obtained by injection-molding with using natural fiber-reinforced thermoplastic resin pellets as a molding feedstock containing natural fibers as reinforcing fibers, has a natural fiber content of from 20 to 60 wt %. The natural fibers have an average length of from 1.5 to 4.0 mm. The natural fiber-reinforced thermoplastic resin injection molding has an electrostatic voltage half-life, as determined by the half-life measurement method specified in JIS L 1094, of less than 40 seconds.

摘要:
A scanning mirror unit for scanning a beam comprises: at least one cantilever which is formed by bonding an elastic material and a piezoelectric material together and supported by a base at its one end; and a movable mirror which is supported at least by a free end of the cantilever at its peripheral part. When voltage is applied to the piezoelectric material, the free end of the cantilever moves in a prescribed direction to press and move the peripheral part of the movable mirror while leaving a central part of the movable mirror at substantially the same position to cause a tilt to the movable mirror. With such composition of the scanning mirror unit, a reflecting member having a sufficient thickness (e.g. some hundreds of microns) can be employed for the movable mirror, by which a high power laser beam effective for treatment of affected parts, etc. can be reflected finely and durably.

This invention relates to a polymer mixture which comprises an aromatic polycarbonate (A); a styrene (or styrene derivative and/or (meth)acrylate) containing polymer or copolymer and/or a styrene (or styrene derivative and/or (meth)acrylate) containing graft polymer (B); phosphorous compound(s) which are phosphate or phosphonate or oligomeric or poly-phosphate based flame-retardant(s) (C); specific inorganic additive(s) (D); and further flame retardant(s) or anti-drip agent(s) (E): and optionally, other additives.
摘要:
A blower nozzle (30) and a vacuum nozzle (40) extending in parallel with each other are connected to a main body (10) housing therein a fan (19) and a motor (20). The main body (10) is provided with a dust bag (50). In a vacuum mode, air is directly sucked from the vacuum nozzle and is introduced into the dust bag by the rotation of the fan. In a blower mode, the air similarly sucked from the vacuum nozzle is directed toward the blower nozzle.
摘要:
A router attachment is provided for converting a small hand-held rotary cutting tool into a miniature router. The attachment has a base having a planar lower surface, a central aperture, an upright column and a handle. A tool holder slidably mounted on the upright column is provided with a clamp for affixing the rotary cutting tool thereto. A height adjustment mechanism enables the user to adjust the height of the tool holder relative to the base planar lower surface and a lock mechanism releasably locks the tool holder to the base column during use.
