A diesel engine idle speed control system and method wherein a preset running characteristic map is corrected by a learning value updated on the basis of the output of a PID under predetermined conditions for each of different engine load modes, thereby determining a desired injection quantity. The map indicates a relationship between an engine speed and a fuel injection quantity for each of accelerator openings, including an accelerator opening of zero percent. A judgment is made on the present load mode of the engine, and a basic injection quantity corresponding to the present accelerator opening and engine speed is calculated from the running characteristic map. When the vehicle operating condition is in an idle mode, learning is executed so as to optimize a feedback correction quantity used for feedback control for each load mode, and a corrected basic injection quantity is calculated from the basic injection quantity and the learning value. Relearning is executed according to a predetermined condition. Updating of the learning value is also executed according to a predetermined condition. A desired injection quantity is obtained by adding the corrected basic injection quantity and the output value of the PID to each other.

A nitrile group-containing rubber latex comprising an aqueous dispersion of a nitrile group-containing highly saturated rubber having an iodine value of not more than 120. The said rubber latex can be produced by converting a solution of a nitrile group-containing highly saturated polymer rubber having an iodine value of not more than 120 in an inert solvent into an oil-in-water emulsion using water and an emulsifier, and removing the solvent from the resulting emulsion.

A method of treating polyester fibers, which comprises(1) treating the polyester fibers with an adhesive composition (AR) comprising a latex (A) of a vinylpyridine/conjugated diene copolymer having a vinylpyridine unit content of at least 20% by weight but not more than 70% by weight and a resorcinol-formaldehyde resin as main components, and(2) further treating it with an adhesive composition (BR) comprising a latex (B) of a ntirile group-containing highly saturated copolymer rubber having an iodine number of not more than 120 and a resorcinol-formaldehyde resin as main components. A composite obtained by bonding the treated polyester fibers to a nitrile group-containing highly saturated copolymer rubber by vulcanization has high initial and heat-resistant adhesion strength, and is useful for production of timing belts and polyribbed belts.

摘要:
A contact lens case including a container main body provided with a housing recess for storing a contact lens and a liquid agent, and a lid that is connected to the container main body via a hinge in a freely openable and closable manner. A lens holding body is displaceably housed in the housing recess, and by connecting the lid and the lens holding body via a connecting member, the lens holding body can undergo rising and falling displacement following open and close action of the lid around the hinge. A displacement restricting member is provided that restricts a direction of the rising and falling displacement of the lens holding body to the vertical direction that coincides with a depth direction of the housing recess.

Three-phase thyristor switched capacitors are delta-connected to three-phase AC buses. Each thyristor switched capacitor includes a reactor, a capacitor, and a thyristor switch that are electrically connected in series. The thyristor switches of the three phases are arranged so that the terminal-to-terminal distance between respective thyristor switches of respective phases are not uniform. The three-phase thyristor switched capacitors are configured so that the thyristor switched capacitors of two of the three phases having a shortest terminal-to-terminal distance therebetween are opposite to each other in terms of connection order in which the thyristor switch and the capacitor are electrically connected along a loop path made up of the delta-connected thyristor switched capacitors.

A propellant tank for storing a liquid propellant A and supplying vapor produced by evaporation of part of the liquid propellant A to an external location comprises a tank body for storing the liquid propellant A, a mesh member arranged inside the tank body to cover a liquid surface of the liquid propellant A to divide an interior of the tank body into a liquid propellant storing area LA and a gas storing area GA by utilizing surface tension of the liquid propellant, and a heater arranged to a gas storing area GA side of the tank body to keep the gas storing area GA at higher temperature than temperature in the liquid propellant storing area LA. The tank body has a propellant inlet open into the liquid propellant storing area LA and a gas outlet open into the gas storing area GA.
摘要:
A method of pilot injection control which avoids a change in the number of pilot injections in a transient response of an engine to improve driving and handling feeling. When pilot injection is performed, it is determined whether fuel injection amount Q immediately before the pilot injection is more than a maximum value Qmax and, if so, number of pilot injections is fixed to a predetermined value. When fuel injection amount Q is determined to be not more than the maximum value Qmax, it is determined whether fuel injection amount Q is lower than a minimum value Qmin, and, if so, the number-fixed control of the pilot injections is released and map control is started where the pilot injection number is determined based on a map.
