Abstract: The invention addresses a problem of obtaining a conjugated polymer having a higher molecular weight through coupling reaction of monomers using a transition metal catalyst. The invention relates to a method for producing a conjugated polymer, which comprises polymerizing one or more monomers through a coupling reaction, wherein the coupling reaction of the monomer is carried out by using one or more kinds of homogeneous transition metal complex catalysts and one or more kinds of heterogeneous transition metal complex catalysts in combination.

Abstract: The invention addresses a problem of purifying a monomer to be a precursor according to a simpler and milder method so as to obtain a polymer having a higher molecular weight. The invention relates to a method for producing a condensed polycyclic aromatic compound having n active groups (wherein n is an integer of 1 or more and 4 or less), which comprises bringing a composition containing the condensed polycyclic aromatic compound and a solvent into contact with zeolite.

Abstract: A transformable toy (100) which is instantaneously changeable from a flat plate-like shape to the shape of a character figure and which is used to play a game by rotating a roulette wheel (189) to compete for the score of attack or defense. A transformable toy comprises character-figure constituting members (111, 122, 131, 141) foldable to a state of a generally flat plate and rotatably connected to each other, elastic members each provided between each of the character-figure constituting members, a roulette wheel (108) attached to any of the character-figure constituting members, a rotation imparting mechanism for imparting rotation to the roulette wheel, and an engaging means (157) for maintaining and releasing the folded state of the character-figure constituting members. When the character-figure constituting members are folded against the elastic forces of the elastic members to operate an engaging member, the character-figure constituting members are rotated and caused to protrude.

Abstract: A tip of a pair of arm portions that integrally extends from a fixed portion and both side portions of a front portion side of a key top are connected with each other in a coupling portion. When a downward pressing force is applied to a center of an operation surface of the key top, a bending moment using a connection portion of a substrate side as a fulcrum and a bending moment using the coupling portion of a tip side as a fulcrum act on the arm portion. The arm portion is deformed into a S-shape having bending deformation portions, and therefore the key top may be lowered in a nearly horizontal posture. The key top has a structure in which both side portions thereof are supported by the arm portions, thereby ensuring a small size and a large elevating stroke.

Abstract: A drying furnace (20) for drying an object (11) by hot air is provided with a heater (36, 38, 43, 45) that applies radiant heat to a hard-heating region (35, 42) having a larger heat capacity than the other region (37, 44) in the object (11) so as to heat the hard-heating region (35, 42) to a temperature approximate to a temperature of the other region (37, 44).

Abstract: A gas fuel injection valve is provided in which a single nozzle member (11) is fixedly provided in a front end part of a valve housing (2), and this nozzle member (11) has formed therein a valve seat (13), a valve hole (45) extending through a central part of the valve seat (13), a throttle hole (46) having a smaller diameter than that of the valve hole (45) and communicating with an outlet of the valve hole (45), and a nozzle hole (48) having a larger diameter than that of the throttle hole (46) and communicating with an outlet of the throttle hole (46), wherein when an internal diameter of the throttle hole (46) is D1, a length of the throttle hole (46) is L1, an internal diameter of the nozzle hole (48) is D2, and a length of the nozzle hole (48) is L2, L1/D1>1??(1) 1<D2/D1?1.2??(2) the above expressions (1) and (2) are satisfied.

Abstract: The following problem associated with optical pickup devices is solved: the temperature of a laser element is increased by excessive temperature rise in a laser driver circuit and this degrades the quality of writing and reading information to and from an optical disc. In an optical pickup enclosure, there is formed a groove recessed into a U shape, extended from the upper surface thereof opposed to an optical disc to the lower surface of the optical pickup enclosure. An air guide passage through which an air flow is passed is formed of this groove recessed into a U shape and a circuit board fastened to the outer circumferential side of the optical pickup enclosure with a screw. At this time, the laser driver circuit element is attached to the side of the circuit board opposed to the air guide passage. In a radiation cover attached to the upper surface of the optical pickup enclosure and in thermal contact with the laser element, an opening is formed.

Abstract: A method for heat exchange between inbound vehicles and outbound vehicles moving through a drying furnace. Conveying tracks, one for the inbound vehicles conveyed into the drying furnace and another for the outbound vehicles conveyed out from the drying furnace, are provided in a single closed cross-section conduit. The closed cross-section conduit is divided in a conveying direction into a plurality of areas. Heat exchange takes place between the outbound vehicles and inbound vehicles in each of the divided areas via atmospheric air in the areas.
