  • Patent number: 8348365
    Abstract: An inkjet printing system includes: a liquid supply tank; a print device with at least one print cartridge, wherein there is an altitude difference between the print cartridge and the liquid supply tank; an internal pressure-adjusting device connecting to the liquid supply tank and the print cartridge; and working software for calculating a preliminary altitude, and a predetermined liquid supplementing altitude of the print cartridge. When a liquid level of a liquid inside the print cartridge is lower than the preliminary altitude and below an lower limit of the predetermined liquid supplementing altitude, the working software controls the internal pressure-adjusting device to suck partial gas from the print cartridge into the liquid supply tank to increase a negative pressure inside the print cartridge, and the liquid stored in the liquid supply tank is introduced into the print cartridge to balance the negative pressure inside the print cartridge.

  • Patent number: 7825882
    Abstract: A dimming method for LED driving circuit is proposed. By temporary switching a pin that is originally used for the input/output of other electric signals to a high impedance node, the dimming control signal may be inputted to dim LEDs. The dimming method comprises the steps of: floating the pin every a period of time to pull the pin's voltage being equal to the dimming control signal; detecting the pin's voltage; and retrieving the dimming control signal in accordance with the detected pin's voltage and thereafter dimming the LEDs.

    Abstract: A semiconductor process apparatus and a SMIF pod used therein. The semiconductor process apparatus comprises a first support, a second support, and a SMIF pod. The first support includes a first pin and a first rotating device, and the first pin is rotated by the first rotating device in a first direction. The second support includes a second pin and a second rotating device, and the second pin is rotated by the second rotating device in a second direction opposite the first direction. The SMIF pod includes a base and a cover. The base includes a slot and an engaging member, and the cover defines a hole for the engaging member to be inserted into. The first pin is inserted into the slot when the SMIF pod is disposed on the first support, and the slot is rotated by the first pin in the first direction so that the engaging member is withdrawn from the hole.
