    Abstract: A digital delaying device for delaying an input signal includes a ring oscillator, a calibration unit, and at least one delay number calculation unit and delay channel. The ring oscillator includes loop-connected delay cells for outputting an oscillation clock. The calibration unit receives a reference clock and the oscillation clock and calculates a pulse number of the oscillation clock corresponding to each reference clock period. The pulse number serves as a period reference pulse number. The calculation unit receives the pulse number and a signal delay value, calculates a signal delay number corresponding to the signal delay value according to the pulse number, and outputs a selection signal. The delay channel includes a multiplexer and cascaded delay cells, which receives an input signal and generates delay signals with different delay timings. The multiplexer selects and outputs one of the delay signals as an output signal according to the selection signal.

    Abstract: A method of manufacturing a fluid injection device. The method of the present invention applies a compensated geometric shape of the unetched isolating portions to increase the additional compensated portion for etching, or the ion implanting process to reduce the etching rate of the unetched isolating portions. Thus, crosstalk or overshoot in the isolating portions of the fluid injection device can be reduced, and the fluid injection device can be precisely manufactured in a small size.

    Abstract: A tape automated bonding (TAB) device for a printhead cartridge of a printer includes a tape having a region capable of being substantially bisected by a centerline that defines a first side of the tape and a second side of the tape. Located on the tape is a printhead, and a plurality of contacts adapted to receive signals from the printer and to provide the signals to the printhead. The contacts are disposed such that the number of contacts on the first side is different from the number of contacts on the second side. The printhead is centrally aligned with the centerline or centrally offset from the centerline.

    Abstract: A pressure-compensation device for adjusting the backpressure inside the cartridge of an ink jet printer includes an accumulator bag, a resilient element, and a motion element. The accumulator bag, installed inside the cartridge, communicates with the external atmosphere through an air duct. The resilient element, kept at a tension state, has a first end connected with the accumulator bag and a second end connected with the motion element. The resilient element restrains the inflation of the accumulator bag so as to induce a backpressure inside the cartridge. The accumulator bag, gradually inflating along with consumption of the ink inside the cartridge, can move the resilient element and the motion element downwards to keep the resilient element at a stable tension state, and thereby a stable backpressure inside the cartridge can be provided.

    Abstract: A safety socket for avoiding danger of shock due to insertion of alien article into the insertion hole. The socket includes two high and two low fixing seats. Two insulative slide boards are reversely disposed on the fixing seats side by side. The lower edge of each slide board is disposed with an elliptic slot for a pin member to pass therethrough, whereby the slide boards can be limitedly left and right slided. The socket further includes two long and two short leaf springs. The short leaf springs abut against front edges of the slide boards. The long leaf springs are fixed on inner walls of a housing of the socket opposite to the short leaf springs. The long and short leaf springs are disposed with convex contact points opposite to each other. When a plug is not inserted into the socket, the slide boards are pushed by the resilient force of the short leaf springs to the center of the socket away from the long leaf springs so as to open the circuit. While when the plug is inserted into the socket, the contact points of the long and short leaf springs contact with each other to close the circuit.
