A micro-droplet generator, comprising a chamber, enclosed by a casing, a spraying plate, having a plurality of spraying holes, a piezoelectric plate, a signal connector, and a storage tank. The piezoelectric plate is mounted inside the chamber, having a fixed end fastened on the casing and a free end performing a bending movement. The input port issues signals that cause the bending movement of the piezoelectric plate. The chamber and the storage tank contain liquid, with a constant difference of liquid levels in the chamber and the storage tank being maintained, so that negative pressure in the chamber is automatically regulated.

An anti-tilt apparatus is provided in the present invention, in which a frame of a vehicle is locked or released for tilt by a locking mechanism controlled according to the vehicle moving status. In addition, the present invention further provides a frame structure of a tilt vehicle wherein the anti-tilt apparatus and an independent suspended wheel set with a tiltable frame are combined together for maintaining certain comfort, good tracking capability and driving safety while the vehicle is moving and swerving. The anti-tilt apparatus of the present invention functions to lock the tiltable frame while the vehicle is operated in low speed or stop and functions to make wheels simultaneously inwardly incline for providing a tilt capability while the vehicle is swerving in high speed so as to increase higher stability and anti-turnover capability of the vehicle.

A controlled odor generator, comprising a central processing unit, at least one micropump unit, a sensor unit and a fan. The micropump unit is housed in a casing containing odorous fluid and has a micropump array for ejecting the odorous fluid in tiny droplets. The central processing unit regulates operation of the micropump unit, allowing to control timing quantity and mixture of spread odor. The sensor unit provides the central processing unit with environmental data, like temperature, air density and humidity, as well as human body states for controlling the micropump unit. Environmental changes are followed by a change of spraying of odor, and varying taste and demand are adapted to.

An engine air intake system comprises a main air duct and at least one bypass air duct, which are located side by side. The bypass air duct is smaller in cross-sectional area than the main air duct which is provided with a throttle contiguous to the bypass air duct having therein a control valve. The throttle and the control valve are regulated by a link mechanism such that the throttle is closed when the engine is operating at a low or intermediate load rate, and that the control valve is opened partially when the throttle remains closed, thereby resulting in an acceleration of air current flowing through the bypass air duct and an improvement in the tumble or swirl ratio. As the engine is operating at a progressively increasing load rate, the throttle is caused to open gradually to bring about an increase in the engine air intake volume so as to enable the engine to operate under the optimum condition.

An electromagnetic diaphragm-type valve has a leakage preventing convex ring and is particularly applicable to air-aided fuel injection system. The valve includes an external housing made of a magnetic-inductive material, an electromagnetic coil set installed inside the rear part of external housing, a magnetic-inductive stator fitted to the central holding site of electromagnetic coil set, and a valve stem installed in the front part of external housing. The valve stem circumference is integrated with a deflectable rubber diaphragm so as not only to enable the valve stem to move a minor distance but also to enable the valve stem to be located in a right or left position. In addition, the diaphragm isolates an air chamber from parts defining the ranges of guidance and lift of valve stem, hence the motion of valve stem is not affected by entrance of pollutants. The diaphragm is formed to seal in compresed air in the air chamber. Effective sealing is achieved because the metal end surface of the valve stem contacts the valve seat by a metal end rubber convex ring. Simultaneously, metal contact between the valve stem and the valve seat prevents serious distortion of rubber and therefore makes the electromagnetic valve highly durable.
