Disclosed is a novel method for the selective molecular conversion of raw material carbon nanotubes containing a mixture of metallic carbon nanotubes and semiconductive carbon nanotubes in a manner that is based on the electrical properties or diameter of the carbon nanotubes. The present invention causes a photoreaction of raw material carbon nanotubes containing a mixture of metallic carbon nanotubes and semiconductive carbon nanotubes with a disulfide or a sulfide of the following formula (I) or (II) (wherein Rand Reach independently represent a hydrocarbon group that may have a substituent) in an organic solvent that contains the raw material carbon nanotubes and the disulfide of the formula (I) or the sulfide of the formula (II), so as to selectively functionalize the metallic carbon nanotubes, or functionalize the carbon nanotubes diameter selectively.

Method for producing selectively functionalized carbon nanotubes

A process for producing functionalized carbon nanotubes, which can organically modify carbon nanotubes with high efficiency, and in particular, can introduce different organic groups into carbon nanotubes with high efficiency through a series of chemical reactions, is provided. Carbon nanotubes are allowed to react with at least one reagent selected from a silyl-substituted organometallic compound and an organometallic compound to obtain a functionalized carbon nanotube reductant, and this functionalized carbon nanotube reductant is then allowed to react with at least one reagent selected from a silyl halide compound and an organohalogen compound to obtain functionalized carbon nanotubes.

Provided are a transparent electroconductive thin film of single-walled carbon nanotubes and its production method capable of further enhancing the electroconductivity and the light transmittance of the film and capable of simplifying the thin film formation process. The method comprises: dispersing single-walled carbon nanotubes of mixed metallic single-walled carbon nanotubes (m-SWNTs) and semiconductor single-walled carbon nanotubes (s-SWNTs) in an amine solution containing an amine having a boiling point of from 20 to 400&#xb0; C. as a dispersant; centrifuging or filtering the resulting dispersion to concentrate m-SWNTs, thereby giving a dispersion rich in m-SWNTs; and applying the resulting dispersion rich in m-SWNTs onto a substrate to form a thin film thereon.

A dust separation section is provided at a suction air passage between a suction opening of a vacuum cleaner main body and an intake opening of a motor fan to separate dust sucked from the suction opening with air and a dust collection section provided at the suction air passage for collecting the dust separated from the air from the dust separation section. Moreover, the dust separation section of the electric vacuum cleaner has a dust guiding space adapted to inflow the dust sucked from the suction opening from one end of the dust guiding space and for guiding the dust from an other end of the dust guiding space to the dust collection section, through a dust strike section, by an inertia force, and an air guiding air passage is provided to guide air from a midstream of the dust guiding space to the intake opening of the motor fan without passing through the dust collection section.

Electric vacuum cleaner provided with a dust separation section for separating sucked dust and dust collecting section for collecting the dust

There is disclosed a vacuum cleaner including a dust separation section which separates air and dust flowing toward an intake port of a motor blower through a connection port of a cleaner main body. The dust separation section includes an air path forming member which performs a separation function. The forming member includes an introductory port, a derivative port, and an opening disposed between these. In the separation function, while dust-containing air flows toward the derivative port from the introductory port, a part of the air is sucked by the motor blower through the opening. Accordingly, the air is separated from the dust which goes straight in the air path forming member with inertia.

A front chassis and a rear chassis of an electronic camera are made of light transmissible resin. The electronic camera has a plurality of light-shielding elements to prevent unnecessary light (external ambient light and internally emitted light, for example) from entering optical systems such as taking lenses and light guides which guide light to an electronic flash control sensor. Further, the shielding elements prevent unnecessary light from entering photoelectric converters such as imaging devices and electronic flash control sensors. These light shielding elements enables the interior components of the camera to be visible therethrough, while ensuring that operational functions of the electronic camera are not adversely affected by entering unnecessary light.

An object of the present invention is to bring a video signal obtained by imaging into a proper level without use of a controllable diaphragm. An imaging apparatus is provided with no controllable diaphragm. Peak detection is performed by a peak detecting circuit for each vertical scanning interval. A peak value is applied to a control device. Necessary shutter speed control in a shutter control circuit, gain control in a pre-amplifier circuit and gain control in a GCA are carried out. Consequently, the level of the video signal obtained by the imaging is adjusted to a proper level without controlling a diaphragm, to obtain an image of proper brightness.
