摘要:
The present invention is directed to a diaphragm for loudspeakers which is integrally constructed through the combination of a core material being formed as a disc-shaped solid construction through the independent or series of combination of a plurality of flat-plate pieces and disc-shaped skin materials each being approximately equal in diameter on the top face and the bottom face of disc-shaped core material, the core material and skin materials being made of either boron or beryllium, thus resulting in the higher efficiency, wider zone and lower distortion of the loudspeakers.

摘要:
Disclosed is a fishing reel seat of the type adapted to attach a fishing reel to a fishing pole and having a stationary ring and a moveable ring adapted to receive the two tangs of the fishing reel. Compound screw threads are formed around the circumference of the main body of the seat for engagement with two locking nuts with threads of opposite hand. The compound thread on the body permits the locking nuts to be tightened against each other by turning in opposite directions to insure a tight locking engagement.

Navigation systems, methods, and programs acquire deviated point information regarding a deviated point where a vehicle traveling a set route has deviated the route, and acquire post-deviation travel history information regarding a travel history after a deviated vehicle has deviated the route at the deviated point. The systems, methods, and programs determine based on the post-deviation travel history information for each of the deviated vehicles whether the deviated vehicle has traveled along a reroute set after deviating the route at the deviated point, and judges whether a rate of the deviated vehicles which were determined as having traveled along the reroute is a first predetermined value or more. If the rate of the deviated vehicles which were determined as having traveled along the reroute is the first predetermined value or more, the systems, methods, and programs determine that guidance of the route is not appropriate.

An object of the invention is to provide a cable support member having high durability and excellent manufacturing performance. A cable support member of the invention includes: a plurality of holding members; and an elastic member. Each holding member has an elastic member insertion passage through which the elastic member is inserted, and has joint surfaces enabling a rotation of the holding member with coming into contact with the adjacent holding members at both sides in the longitudinal direction. The elastic member is inserted through the elastic member insertion passages in the holding members so as to align and maintain the holding members, and exerts a compression force on the holding members. With such a configuration, a neutral state where the cable support member is substantially in a linear fashion and a curved state where the cable support member is bending-deformed are obtainable.

A method for treating an isocyanate residue, which comprises carrying out a thermal decomposition reaction of a carbamate that is produced by the reaction among an amine, urea and/or an N-unsubstituted carbamic acid ester and an alcohol to produce a decomposition solution, separating an isocyanate and the alcohol from the decomposition solution to produce the isocyanate residue, and bringing the isocyanate residue into contact with high-pressure/high-temperature water to decompose the isocyanate residue into an amine; and a method for treating a carbonate, which comprises bringing the carbonate into contact with high-pressure/high-temperature water to decompose the carbonate into an alcohol.

The conductivity test jig includes: a jig main body; a holding member; a conductivity test unit; a conductivity member; an air cylinder; a jig main body; and a second air cylinder. The jig main body has a hole for receiving the connector. The holding member holds the connector in the hole. The conductivity test unit is detachably attached to the connector. When the conductivity test unit moves close to the connector, the conductivity member is electrically connected to the terminals of the connector. The air cylinder makes the conductivity test unit contact the connector, and removes the conductivity test unit from the connector. The push-out member is interposed between the connector and the jig main body in an insertion direction of the connector in the hole. The second air cylinder moves the push-out member in the insertion direction.

An electronic camera includes: an image-capturing unit with variable image-capturing sensitivity, which captures an image of a subject through a photographic lens; a brightness detection unit that detects subject brightness; an exposure calculation unit that executes an exposure calculation by using, at least, the image-capturing sensitivity set at the image-capturing unit and the subject brightness having been detected; a flash quantity calculation unit that calculates a main flash quantity for a flash unit that illuminates the subject when capturing an image thereof; and a sensitivity adjusting unit that adjusts the image-capturing sensitivity so as to achieve optimal exposure with a main flash quantity within a flash quantity control range of the flash unit when the main flash quantity having been calculated by the flash quantity calculation unit is outside the flash quantity control range. And if the image-capturing sensitivity has been adjusted by the sensitivity adjusting unit, the exposure calculation unit re-executes the exposure calculation.
