Patent number: 7691314Abstract: In an injection compression molding method, dies are clamped with low pressure and a melted thermoplastic resin composition is filled in a cavity space from a gate while moving the cavity space relative to the gate, and then the dies are clamped with a high pressure substantially simultaneously with completion of the filling to compress and form the thermoplastic resin composition filled in the cavity space.

Patent number: 7691356Abstract: A by-product mixture produced in a process for producing polycrystalline silicon is made to react with chlorine to form tetrachlorosilane (STC) distillate in a chlorination reaction vessel, and the tetrachlorosilane (STC) distillate is made to react with hydrogen in a hydrogenation reaction vessel to be converted into trichlorosilane (TCS). In the chlorination step, methyl chlorosilanes having boiling points close to TCS are hyper-chlorinated to be converted into hyper-chlorinated methyl chlorosilanes having higher boiling points, which facilitates the hyper-chlorinated methyl chlorosilanes to be separated into high concentration, and inhibits carbon from contaminating the polycrystalline silicon. A donor/acceptor eliminator is provided in the circulation cycle for producing TCS, and accordingly there is no need to take out a by-product produced in the process for producing TCS to the outside of the system, which can highly purify the TCS.Type: GrantFiled: August 12, 2008Date of Patent: April 6, 2010Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Takaaki Shimizu, Kyoji Oguro

Patent number: 7691357Abstract: A by-product mixture produced when polycrystalline silicon is deposited on a base material in a CVD reactor is made to react with chlorine to form a tetrachlorosilane (STC) effluent in a chlorination reaction vessel, and the tetrachlorosilane (STC) distillate is made to react with hydrogen in a hydrogenation reaction vessel to be converted into trichlorosilane (TCS). In the chlorination step, poly-silane contained in the above described by-product mixture can be efficiently recycled as a raw material for producing the polycrystalline silicon, which can enhance a yield of the production process. In addition, in the chlorination step, methyl chlorosilanes having boiling points close to TCS are hyper-chlorinated to be converted into hyper-chlorinated methyl chlorosilanes having higher boiling points, which facilitates the hyper-chlorinated methyl chlorosilanes to be separated into high concentration, and reduces carbon contamination of the polycrystalline silicon.Type: GrantFiled: August 12, 2008Date of Patent: April 6, 2010Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Takaaki Shimizu, Kyoji Oguro, Takeshi Aoyama

Patent number: 7691359Abstract: The invention incorporates new processes for the chemical modification of carbon nanotubes. Such processes involve the derivatization of multi- and single-wall carbon nanotubes, including small diameter (ca. 0.7 nm) single-wall carbon nanotubes, with diazonium species. The method allows the chemical attachment of a variety of organic compounds to the side and ends of carbon nanotubes. These chemically modified nanotubes have applications in polymer composite materials, molecular electronic applications, and sensor devices. The methods of derivatization include electrochemical induced reactions, thermally induced reactions (via in-situ generation of diazonium compounds or pre-formed diazonium compounds), and photochemically induced reactions. The derivatization causes significant changes in the spectroscopic properties of the nanotubes. The estimated degree of functionality is ca. 1 out of every 20 to 30 carbons in a nanotube bearing a functionality moiety.Type: GrantFiled: August 1, 2003Date of Patent: April 6, 2010Assignee: William Marsh Rice UniversityInventors: James M. Tour, Jeffrey L. Bahr, Jiping Yang

Patent number: 7691360Abstract: The present invention is concerned with a process and a plant for the production of sulphuric acid wherein a sulphur dioxide-containing feed gas is converted, at least in part, with oxygen in at least two contact stages of main contacts arranged in series, to generate sulphur trioxide, and wherein generated sulphur trioxide-containing gas is conducted to an absorber and converted therein to sulphuric acid. In order to be able to economically process feed gases of a sulphur dioxide content of between 13 and 66% by volume to sulphuric acid, using conventional catalysts, it is suggested to withdraw from a contact stage connected upstream of the last main contact stage, a partial stream of the sulphur dioxide- and sulphur trioxide-containing gas, to mix the said partial stream with the feed gas to generate a contact gas of a sulphur dioxide content of more than 13% by volume, and to return the same to the first contact stage.Type: GrantFiled: October 21, 2003Date of Patent: April 6, 2010Assignee: Outotec OyjInventors: Karl-Heinz Daum, Ekkehart Seitz, Hermann Müller, Nikola Anastasijevic
