    Abstract: A driving circuit for a piezoelectrically actuated pump includes a boost converter, a control circuit and a voltage switch circuit. The boost converter outputs a constant voltage. The control circuit includes a voltage-division circuit, a comparator and a frequency adjustment circuit. The constant voltage is divided by the voltage-division circuit into a first voltage and a second voltage. The comparator compares first voltage with second voltage so as to output a positive voltage or a negative voltage. The voltage switch circuit receives and feedbacks positive voltage or negative voltage to the piezoelectric actuator load. The control circuit and the voltage switch circuit form a resonant circuit to control the piezoelectric actuator load according to the variety of minor voltage outputted form the piezoelectric actuator load. The frequency adjustment circuit detects and adjusts the variety of the minor voltage automatically so as to adjust operating frequency of the piezoelectric actuator load.

    Abstract: A rapid printing apparatus is selectively operated in a two-dimensional printing mode or a three-dimensional printing mode. The rapid printing apparatus includes a sheet material supplying mechanism, a printing mechanism and a laminated sheet processing mechanism. The sheet material supplying mechanism is used for supplying a sheet material. The printing mechanism is used for printing on a specified area of the sheet material. In the two-dimensional printing mode, the laminated sheet processing mechanism cuts the printed sheet material to a specified size and collects the printed sheet material. In the three-dimensional printing mode, the laminated sheet processing mechanism cuts the printed sheet material to plural sheet segments with the specified size and laminates the plural sheet segments into a three-dimensional laminated block.

    Abstract: A rapid prototyping apparatus includes a construction platform, a movable platform, and a page-width array printing module. The construction platform includes a construction chamber. The movable platform and the construction platform are movable relative to each other. The page-width array printing module includes plural inkjet head structures. The printing platform and the movable platform are synchronously moved along a single direction in a reciprocating motion. The plural inkjet head structures are collaboratively defined as at least one page-width array printing unit. The plural inkjet head structures include respective inkjet chips. The inkjet chips are arranged in plural rows and in a staggered form, so that a printing width of the inkjet chips is larger than or equal to a width of a printed pattern. Moreover, at least one monochromatic print liquid is introduced into the construction chamber from the plural inkjet head structures.
