摘要： An inhibitor contains naphthyridine dimer, a naphthyridine-azaquinolone hybrid, a trinaphthyridine-azaquinolone hybrid, or a trinaphthyridine-azaquinolone hybrid derivative. In order to inhibit binding of 100 nM of RRE to 100 nM of Rev protein, for example, an inhibitor containing naphthyridine dimer is used at a molarity of 1.2 μM to 12 μM, an inhibitor containing the naphthyridine-azaquinolone hybrid is used at a molarity of 2 μM to 20 μM, or an inhibitor containing the trinaphthyridine-azaquinolone hybrid derivative is used at a molarity of 200 nM to 2 μM. This makes it possible to effectively inhibit binding of RRE to Rev protein.

摘要： A television signal receiving apparatus which can read program information relevant to a television program from an optical disk medium, interlocked with the television program and can reproduce and display the read program information. Program information (broadcasting information including program names, broadcasting channel names and broadcasting dates and times and appendant information relevant to the contents of the programs) relevant to the television programs to be displayed by the television receiver/display is recorded in the optical disk medium. When a user instructs a display of the program information by the selection and decision input unit, the television control unit transmits the display request and time information from the clock apparatus to the control unit of the optical disk unit. The control unit makes the appendant information to be reproduced from the optical disk medium, by using the broadcasting channel name and the time information as retrieval information. The appendant information is sent to the television receiver/display through the interface and is displayed in a picture and sound.

摘要： A gas turbine combustor comprises an inner cylinder provided with louvers in an outer periphery thereof, defines a head combustion chamber and a main combustion chamber located downstream of and greater in diameter than the head combustion. An outer cylinder surrounds the inner cylinder and defines an air passage therebetween. A first burner communicates with the head combustion chamber and supplies air with gaseous fuel, and a second burner being disposed in the air passage near the head combustion chamber and supplying air and gaseous fuel into the main combustion chamber. The second burner is formed with a plurality of air inlets by a plurality of vanes which are disposed in an annular passage and which swirl the air, and with gaseous fuel jet ports near the inner peripheries of the air inlets. When the flow rate of the supplied fuel is small, the fuel flows along an inner-peripheral surface of the second burner, and when the flow rate is large, the fuel from the air inlets moves from the inner-peripheral surface toward the outer-peripheral surface of the second burner so as to be mixed well with the air supplied into the main combustion chamber. Thus, the production of NO.sub.x, CO, HC etc. can be decreased over the whole operating range of the turbine.
