Patent number: 6228336Abstract: A dust collecting apparatus and method for dedusting a Ca-containing gas using a ceramics filter is provided, in which a filter differential pressure elevation rate is suppressed. A desulferizing agent 103 and a mineral 106 containing MgO are supplied via a hopper 13, 15 a valve 14 and a feeder 16 into a pressurized fluidized-bed combustion furnace 1 together with coal 101 and air 102. A combustion gas 201 is dedusted by a cyclone 2 to become a combustion gas 301, the combustion gas 301 enters a filter container 3a, 3b having a ceramics filter 31a, 31b and is further dedusted. A combustion gas 401 which is dedusted is supplied into a gas turbine 4 to generate power, and combustion gas 501 heats a waste heat recovery boiler 5 which in turn drives a steam turbine 7. The mineral 106 containing MgO is added in the combustion gas 301 which flows in the ceramics filter 31a, 31b. Thereby MgO is added to the combustion gas so that the filter differential pressure elevation rate can be suppressed.Type: GrantFiled: August 13, 1999Date of Patent: May 8, 2001Assignees: Hokkaido Electric Power Company, Inc., Mitsubishi Heavy Industries, Ltd.Inventors: Yasuo Katsuki, Takashi Ohnishi, Shozo Kaneko, Akira Hashimoto, Yuichi Fujioka, Kikuo Tokunaga, Toshihiko Setoguchi

Patent number: 5952086Abstract: A titanium target for sputtering high in film making efficiency in a contact hole. The crystallization on the target face is caused to be orientated so that the X-ray diffraction strength of the (10 -10) and/or (11 -20) vertical to the close-packed filling face may become 1.1 times or more in a case of the random orientation, and the X-ray diffraction strength of the (0002) parallel to the close-packed filling face may become 1 time or lower in a case of the random orientation. A direction of the sputter grains jumping out of the target face is controlled in a direction vertical to the target face.Type: GrantFiled: November 12, 1996Date of Patent: September 14, 1999Assignee: Sumitomo Sitix of Amagasaki, Inc.Inventors: Takashi Ohnishi, Yasunori Yoshimura, Setsuo Okamoto

Patent number: 4270003Abstract: The novel hydroquinone derivatives of the formula (I) are useful intermediates for the preparation of coenzyme Q, vitamin K and the polyprenyltrimethylquinones: ##STR1## wherein R.sup.1 is lower alkyl, lower alkoxy lower alkyl or methoxyethoxymethyl, R.sup.2 and R.sup.3 are each methyl or methoxy, or R.sup.2 and R.sup.3, taken together with the carbon atoms from which they depend, define a benzene ring, and R.sup.4 is a substituted or unsubstituted aromatic hydrocarbon. The compounds (I) are readily prepared either by reacting a Grignard reagent of the formula (II) with a halosulfone (III) in the presence of a copper compound, or by reacting a copper derivative (II') of the Grignard reagent (II) with a halo-sulfone (III), as follows: ##STR2## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are defined as above, and X is a halogen atom or a tosyl group.Type: GrantFiled: July 30, 1979Date of Patent: May 26, 1981Assignee: Kuraray Co., Ltd.Inventors: Yoshiji Fujita, Takashi Ohnishi, Takashi Nishida

Patent number: 4122119Abstract: There is disclosed a process for preparing unsaturated ketones especially terpenoid ketones, by subjecting a substituted propargyl alcohol of formula (II) ##STR1## wherein R is a group containing 1 or 2 substituted or unsubstituted alkyl- or alkylene units containing 4 carbon atoms each to a thermal treatment sufficient to rearrange its structure in order to obtain structurally isomeric unsaturated ketones of formula I ##STR2## wherein one of the substituents X.sub.3 and X.sub.4 is hydrogen and the other and Z.sub.2 together form a bond. The process can be effected in the presence of an isomerization catalyst, which leads to high percentage of .alpha...beta.,.gamma...delta.-unsaturated ketones.
