摘要： PURPOSE:To obtain an expanded graphite for coating film of graphite by intercalating a specific guest substance between layers of graphite to form an intercalation compound and quickly heating the intercalation compound by laser processing. CONSTITUTION:Potassium and graphite are charged into an argon purged glove box 4 so as to provide stoichiometric ratio (KC12) and the interior of the box is evacuated once and NH3 gas is introduced and NH3 gas is condensed by a chloroform slush bath (at -60 deg.C) and allowed to react with potassium in a liquid phase. Then the graphite is fed thereto and allowed to stand at ordinary temperature to afford the intercalation compound K-NH3-GIC. Then the intercalation compound is dropped into a hopper 7 in an expanding device B and further dropped on a feeder 8 and carried forward. An irradiation window consisting of window flat glass 9 is fitted above an irradiation part of the top and a continuous oscillation YAG laser 11 is arranged through both convex lens 10 thereon and the intercalation compound 6 is irradiated with laser beam (e.g. of 1.05mum wavelength) to expand graphite and then the expanded graphite is recovered by dropping.

摘要： PURPOSE:To obtain fine flaky particles having superior anisotropy by intercalating a guest substance between the layers of graphite to form an intercalation compd. and crushing this compd. in vacuum. CONSTITUTION:A guest substance such as K, K-NH3, Br, FeCl3 or SbCl5 is intercalated between the layers of graphite to form an intralaminar compd. This compd. is finely flaked by crushing in vacuum or in an atmosphere of an inert gas or dry air optionally after expansion by rapid heating. When the resulting fine flaky graphite is mixed with a solvent, oil, etc., and used to form a graphite coating film, a long service life and high reliability are obtd.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing an ultrafine structure by which ultra refinement and high density is realized with a high throughput. SOLUTION: This method for manufacturing an ultrafine structure is provided with a step of selectively forming linear active areas ST in which dangling bond remains by supplying Ag which is combined with the dangling bond onto a Si (111) 7×7 substrate having dangling bond, a step of forming a one- dimensional molecular mask in the active areas ST by depositing fullerene C6031 and combining it with the remaining dangling bond, a step of growing an amorphous silicon layer 41 whose force of combining with the fullerene C6031 is far smaller than its force of mutual combination and a step of exposing the fullerene C6031 by activating the amorphous silicon layer 41 and moving it between areas of the one-dimensional molecular mask.

摘要： PROBLEM TO BE SOLVED: To provide a differential type measuring device for the degree of electrical movement, whereby it is possible to accurately measure the size of particulate under the low pressure condition. SOLUTION: Charged particles drawn in from one slit 4 move downward along the center axis together with a sheath gas supplied from a discharge hole 7 in an enclosure 2, and each particulate is drawn toward a center rod 3 from the side with the enclosure 2 at a speed complying with the degree of electrical movement upon being influenced by the electric field generated by a voltage V impressed by a variable voltage source 10 between the inside circumferential surface of the enclosure 2 and the peripheral surface of the center rod 3. Only those particulates having specified size are taken out, which have advanced for the distance L in drawing the specified locus and reached the other slit 5 in the center rod 3. The sheath gas supplied from a draw-in hole 7 in the enclosure 2 is exhausted from the discharge hole 9 in the enclosure 2 upon passing through the slit 5, but because an orifice 11 is provided in the downstream of the slit 5, the sheath gas is hindered from flowing, and a pressure difference is generated between in front of and behind the orifice 11.

摘要： PROBLEM TO BE SOLVED: To obtain a photosensitive resin compsn. using a relatively small amt. of Fullerene and curable with visible light. SOLUTION: This photosensitive resin compsn. contains Fullerene and a high molecular compd. having a functional group capable of reacting with the Fullerene under irradiation with visible light. A negative type image element is formed as follows; a layer of this compsn. is formed and irradiated with visible light through a photomask having a visible radiation transmitting pattern, the irradiated part in the layer is cured and the uncured part in the layer is removed to form a patterned resist film. A device is produced by etching an image forming layer through the resist film and then removing the resist film.

摘要： PURPOSE:To produce a large particle obtained by aggregating and chaining primary particles by chaining primary particles formed by condensing a molecule in a substance forming a nucleus when ionized by aggregation to form a secondary particle and increasing a size of a produced superfine particle. CONSTITUTION:The electron of UF5 molecule is separated by the irradiation with a light source 12 provided to a laser isotope separator 10, hence the UF5 molecule is ionized, and a stable nucleus is immediately generated. The nucleus thus ionized polarizes the surrounding UF5 molecule as it is excited by the light source 12, the surrounding UF5 molecule is rapidly condensed by an electric force to form a large-sized primary particle, both poles of the primary particle are charged with the irradiation of the light source 12 even after the primary particle is formed, the aggregation of the primary particles is promoted, and a large-sized chained UF5 particle is obtained.

摘要： PURPOSE:To sufficiently utilize the benefit obtained by the use of an ultrasonic nozzle and to prevent the damage of an optical window, by allowing two or more kinds of laser beams different in a wavelength irradiating a working substance to cross each other. CONSTITUTION:Two kinds of infrared laser beams 2, 3 different in a wavelength are allowed to irradiate the working substance in an ultrasonic nozzle 1 in such a state that the optical axes thereof cross each other at a right angle. The overlapped part of the laser beams 2, 3 is limited to the central part of the nozzle 2 and no dissociation reaction is induced in the vicinity of the inside part of optical windows 4, 4' permitting the transmission of the laser beams 2, 3. As a result, since no infrared multiple photo dissociation is induced in the gaseous working substance not supercooled in the vicinity of the inner wall of the ultrasonic nozzle 1 or low pressure reaction container 7, the benefit obtained by the use of the ultrasonic nozzle 1 can be sufficiently obtained. Further, since it is avoided that highly intensity infrared laser beam is applied to the optical windows 4, 4', the damage of the optical windows 4, 4' can be prevented.

摘要： PURPOSE:To facilitate the formation of a thin polytetrafluoroethylene film on a desired area of the surface of a solid, by polymerizing a sample gas near the surface of the solid by selective exposure to laser beams. CONSTITUTION:A base 8 is placed in a glass vessel 4 and a sample gas 5 (e.g., CHF3, CHClF2, or C4F8) is sealed within the vessel (numeral 3 is a window comprising an optical crystal). Laser beams 1 (e.g., CO2 or Ar ion laser) are allowed to strike on a sample gas present near the surface of a desired area of the base 8 through a lens 2 to form a region 6 in which CF2 radicals or excited C2F4 molecules are generated and to coat the base 8 selectively with a thin polytetrafluoroethylene film 7 formed by the polymerization of the excited molecules.
