Abstract: Construction machinery which is capable of improving fuel efficiency of the engine and also capable of effectively utilizing surplus energy in a light-load mode. The construction machinery includes an engine, a hydraulic pump driven by the engine, and actuators driven by oil pressure supplied from the hydraulic pump. In the light-load mode where the engine torque at the intersection point of an iso-horsepower curve of the necessary horsepower and a governor characteristic curve of the engine is smaller than that of a rated output point of the engine, the number of revolutions of the engine is reduced while the engine torque is increased with respect to the intersection point, and the horsepower is made to exceed the iso-horsepower curve. With surplus torque generated therefrom, a power generator is operated so as to generate electric power, which is stored in a power accumulation apparatus.

Abstract: Disclosed in a novel liquid-crystalline compound which is a naphthalene derivative useful as an electro-optical liquid crystal display material, a liquid crystal composition containing such naphthalene derivatives and a liquid crystal display device comprising the same. The naphthalene derivative provided by the present invention exhibits an excellent liquid-crystallinity and miscibility with currently widely used liquid crystal compositions or compositions. The addition of the naphthalene derivative makes it possible to drastically lower the threshold voltage of the liquid crystal composition while maintaining its high response. The naphthalene derivative of the present invention is characterized by a large birefringence index. Further, most of the naphthalene derivative of the present invention has no strongly polar group in its molecule and thus can also be used for active matrix driving.

Abstract: An epoxy resin cured article has a high glass transition temperature and low dissipation factor. An epoxy resin composition from which the cured article can be having excellent solubility in solvents is used to produce the cured articles. A polyester as a curing agent of an epoxy resin composition having an aromatic polyhydroxy coumpound residue including an aryloxycarbonyl group at the molecule of the terminal, an aromatic polyvalent hydrocarbon group residue, and bulky structure, is used. Since the curing agent behaves as a polyfunctional curing agent, a cured article produced therefrom has a high crosslink density. Since highly polar hydroxyl groups are not formed during curing, a cured article has high glass transition temperature and a low dissipation factor. The cured article does not release low molecular weight carboxylic acids though hydrolysis of ester bonds at crosslinked bonds.

Abstract: The electrical connector has a main housing and a turnable member turnably supported on the main housing.

The connector has a resilient engagement arm extended from the turnable member, a stopper projection formed in the resilient engagement arm, a guide portion formed in the main housing, and an engagement recess formed in the main housing. The stopper projection abuts against the guide portion so that the resilient engagement arm is in a yielded condition at a half-way mating state of the main housing with the second connector, while the stopper projection locks with the engagement recess by resiliency of the engagement arm when the main housing has completely coupled with the second connector.
