Abstract: A lower structure of a vehicle door includes a door body, a garnish, and an elastic seal. The door body is attached to a door opening of a vehicle body so as to be openable. The garnish covers an outer lower portion of the door body. The elastic seal includes a holding portion that clamps a flange portion at a lower end of the door body. The elastic seal is joined to the garnish. The garnish is supported by the door body via the elastic seal.

Abstract: A curing agent for epoxy resin, and a coating composition using the curing agent curing agent that delivers excellent recoatability and overcoatability after a long time exposure. (A) An epoxy curing agent that is derived by adduction between amide-type reactants from polyamine compounds comprising from 25-75 mol % of a polyoxyalkylene-polyamine and carboxylic acids or a mixture thereof and glycidyl ether compound; (B) An epoxy curing agent of the mixture of (B1) amide-type reactants prepared through polyoxyalkylene-polyamine and carboxylic acids or a mixture thereof, and (B2) a reactant is derived by adduction between other aliphatic polyamines or a mixture thereof and glycidyl ether compound. Coating composition comprising the epoxy curing agent of the above described A or B.

Abstract: A control device for an actuator adapted to control a discharge pressure of a variable discharge pump by means of a regulator and capable of ensuring sufficient flow control range of change-over valves with respect to a spool stroke even when the number of rotations of an engine for driving the variable discharge pump is reduced to decrease a discharge rate of fluid from the variable discharge pump. Elastic force of a spring of a valve constituting the regulator is adjusted by means of a cylinder associated with a throttle lever for controlling the engine. Also, a control valve is arranged so as to be associated with the throttle lever, so that a pressure on a downstream side of the variable discharge pump is increased to change over the valve.

Abstract: A device for controlling multiple hydraulic actuators to protect a system from an overpressure caused by increasing the load on an individual actuator. By controlling the supply of hydraulic fluid to a pair of cylinders each associated with a pilot valve so that each cylinder always has enough fluid pressure to operate, the device of the present invention prevents the shutdown of the device caused by too much fluid going to the actuator operating at the maximum pressure. Thus all actuators continue to operate even if one is overpressured.

Abstract: A covering composition comprising an ionomer resin and a low-molecular weight polyethylene wax has improved impact resistance. A golf ball having a core enclosed in a cover thereof is fully durable and exhibits satisfactory flying performance.
