摘要:
A straddle type vehicle includes a protrusion which is displaced together with a throttle valve, a lever pulley which is displaced in response to the rotation of a throttle grip, a spring and a control device. The spring generates elastic force to return the protrusion to a first original position when the lever pulley is in a second original position. The spring maintains the lever pulley in the second original position by being elastically deformed until the protrusion reaches a predetermined position in which the protrusion is displaced from the first original position in such a direction that the throttle valve opens when the lever pulley is in the second original position. The control device opens the throttle valve by displacing the protrusion until the protrusion reaches the predetermined position in a gear shift change when the throttle grip is fully closed.

An Ni—Ti—Nb based multiple phase alloy consists of a combined phase which comprises a phase for the hydrogen permeability and a phase for the resistance to hydrogen embrittlement. The alloy has a composition satisfying the formula: NixTiyNb(100-x-y) in which x=25˜45 mol % and y=25˜55 mol %. A metal membrane for hydrogen separation-purification is prepared using the alloy material. The alloy material is prepared by blending Ni, Ti and Nb and melting the blend. The metal membrane permits the hydrogen separation-purification and thus the resulting purified hydrogen gas can be used as a fuel and can be applied to fields of production of semiconductors.
摘要:
An engine control device capable of decreasing engine output while giving less uncomfortable feeling to the rider in the event of a failure, with a simple configuration. Engine output is decreased when a failure has been detected in a throttle valve. When engine speed after the occurrence of the failure is larger than preset target rotational speed at the time of the occurrence of the failure, an ignition of the engine is cut off. The engine speed thereby can be decreased according to the preset target rotational speed. Thus, engine output can be decreased uniquely.

[Problem] To provide an electronic throttle valve control system which can prevent rapid rotation of a throttle valve reliably when the control system has a failure.[Solution] A throttle valve 10 for controlling the amount of intake air to an internal combustion engine, an electric motor 20 for driving the throttle valve 10, and a rotational speed reduction mechanism 30 for reducing the rotation of the electric motor 20 to control the rotation of the throttle valve 10 are provided. The rotational speed reduction mechanism 30 has an urging mechanism 31 for urging the throttle valve 10 in the closing direction. The rotational speed reduction mechanism 30 is connected to an attenuation mechanism 38(20) for attenuating the speed at which the throttle valve 10 is rotated in the closing direction by the urging force of the urging mechanism 31 when the control system has a failure. The attenuation mechanism 38 is constituted of the electric motor 20 in a regenerative mode or an air damper.

A terminal connector includes a knob at its outer end. A knob cover snaps into the knob to enable rotation of the knob. The knob cover has resiliently urged lock tabs which snap over lock steps on the knob and into grooves beyond the lock steps. The sides of the lock tabs engage sides of the grooves to transmit torque to the knob. The knob covers are color coded so that a selected color can be installed on a selected knob to indicate its function. An insertion prevention lid is integrally molded over a plug insertion opening of the knob cover to prevent insertion of a connector plug therein. A frangible perimeter of the insertion prevention lid permits its removal to enable insertion of a connector plug.

A waste water treatment apparatus which is compact, and excellent in durability, has a high treatment performance and can stably operate for a long time is provided. In a waste water treatment apparatus at least comprising a waste water treatment tank in which a carrier particle immobilizing a microbe is charged and decomposing and eliminating an organic matter and/or an inorganic matter contained in a waste water, and a membrane module for filtrating a water to be treated which flows out from said treatment tank, a non-permeating water not passing thorough the membrane module is returned and circulated to said treatment tank. In a waste water treatment apparatus at least comprising a waste water treatment tank in which a carrier particle immobilizing a microbe is charged and decomposing and eliminating an organic matter and/or an inorganic matter contained in a waste water, a carrier immobilizing a microbe is an acetalized polyvinyl alcohol hydrogel.
摘要:
A fuel pump is composed of a permanent-magnet motor section and a pump section. The yoke of the motor section is designed as a part of the magnetic circuit which is saturated with magnetic flux. The quantity of the discharged fuel is adjusted by covering from outside an auxiliary yoke which is changeable according to a difference between the actual quantity of the discharged fuel and a required quantity of the fuel.
