摘要:
An oscillation frequency changing means is inserted between a tuner and an oscillator of local oscillator (56) of a high frequency receiving device, and the oscillation frequency changing means, in each frequency band received, changes the oscillation frequency characteristic of local oscillator (56) in relation to the tuning voltage supplied from PLL circuit (78), and operates in accordance with the frequency characteristic of tuning filter (52, 54, 62, 64) to obtain an oscillation signal varied just by a predetermined frequency, thereby making it possible to receive broadband channels of continuous VHF broadcast band and UHF broadcast band.

Described in the present invention are a sulfonyl derivative represented by the following formula (I): Q1—Q2—T1—Q3—SO2—QA (I) [wherein Q1 represents a saturated or unsaturated 5- or 6-membered cyclic hydrocarbon group, 5- or 6-membered heterocyclic group, dicyclic fused ring or tricyclic fused ring group which may have a substituent; Q2 represents a single bond, an oxygen atom, a sulfur atom, a linear or branched C1-6 alkylene group or the like; QA represents an arylalkenyl group which may have a substituent or a heteroarylalkenyl group which may have a substituent; and T1 represents a carbonyl group or the like] and a medicament comprising the same. The compound has strong FXa inhibitory action, provides prompt, sufficient and long-lasting anti-thrombus effects when orally administered, and has low side effects and is therefore useful as an excellent anticoagulant.
摘要:
This invention provides novel genes encoding enzymes which decompose difficult-to-decompose thiophene compounds. By using these genes, sulfur atoms can be released from the thiophene compounds in fossil fuel such as petroleum, and the diffusion of sulfur into the environment caused by the combustion of the fossil fuel can be prevented.

A two-component developer consists of a toner, which contains at least a resin and a colorant and to which an external additive is added, and a carrier. This two-component developer has the toner that has a number average molecular weight (Mn) of 3,000 or less and contains particles having a molecular weight of 1,000 or less at 40 number % or more, and also has the carrier that satisfies general formula (1) as follows: 3,000,000≦&sgr;1000×Dc3≦20,000,000 (1) where &sgr;1000 represents a magnetization (emu/g) of a carrier at 1,000 oersted, and Dc represents volume average particle diameter (&mgr;m) of the carrier.

A two-component developer includes a toner containing toner particles with a volume diameter of 8 &mgr;m or less, and a carrier containing carrier particles, each carrier particle including at least one core particle and a carrier core coating layer, the carrier core coating layer being made of a silicone resin and a silicone oil, the carrier having a fluidity of 45 seconds or less.
摘要:
The present invention relates to a method of degrading organic sulfur compounds, in which organic sulfur compounds are decomposed by a microorganism belonging to the genus Paenibacillus and having the ability to decompose organic sulfur compounds. Heterocyclic sulfur compounds can be decomposed by specifically cleaving their C--S bonds under high-temperature conditions.
摘要:
The present invention provides a flame-retardant resin composition comprising 100 parts by weight of a bromine-containing copolymer composition containing 1 to 40% by weight of bromine, and comprising 0 to 30 parts by weight of a flame-retarding adjuvant and 0.5 to 30 parts by weight of a polyorganosiloxane-reinforced resin component obtained by polymerizing a vinyl monomer (d) in the presence of a polyorganosiloxane polymer. The flame-retardant resin composition of the present invention has attained a remarkably higher flame retardancy by the inclusion of a polyorganosiloxane-reinforced resin. A significant improvement in the dripping phenomenon has also been achieved. Further, this composition exhibits superior impact resistance and moldability, and a superior outer appearance in the formed products.
摘要:
In an electrophotographic or electrostatic image forming device, the toner concentration of a two-component developer, i.e., a mixture of toner and carrier is measured on the basis of an output of a magnetic bridge type concentration sensor responsive to the magnetic permeability of the developer. The sensor has a surface whose mean roughness along the center line is less than 0.4 .mu.m Ra.

摘要:
A flame retardant resin composition which includes the following component (A) and component (B) blended in the ratio (A):(B)=100:1-40 parts by weight. Component (A) is a thermoplastic resin including 0-70% by weight of a rubber component and 100-30% by weight of a polymer component formed from monomers comprising a methylated aromatic vinyl monomer and an hydroxylated aromatic vinyl monomer and, optionally, an aromatic vinyl monomer other than the above monomers, a cyanated vinyl monomer, a (meth)acrylic acid ester monomer, maleic anhydride, and a maleimide monomer; graft ratio of the thermoplastic resin being 10-150% when the rubber component is used. Component (B) is a flame retarder.
