Publication number: 20090074624Abstract: A liquid transfer device is provided for biochemical assay, including a pipette forming an interior space extending in an axial direction and having first and second ends. The first end forms an opening and the second end forms an enclosed variable volume, whereby variation of the volume causes a change of pressure to selectively induce a suction force and a releasing force in the pipette. An analysis container includes a plurality of receptacles retained by a slab. A film covers the slab to seal the container. A movement control device includes a manipulator that releasably holds the pipette and a tray that forms a cavity for receiving and retaining the container. The pipette and the tray are movable with respect to each other in order to fill/draw test agent into/out of the receptacles.Type: ApplicationFiled: May 21, 2008Publication date: March 19, 2009Inventor: Don Liang

Publication number: 20090051243Abstract: The present invention relates to a micro actuator, which is located on a substrate and includes a plate and a bushing. A rear end of the plate exhibits a tapered triangular shape or an arc-like shape or has at least a bump disposed on a bottom surface of the rear end of the plate, making that a non-planar contact is present between the rear end of the plate and the substrate when both are contacted, so as to effectively reduce the friction and driving voltage and prolong the lifespan of components.Type: ApplicationFiled: September 20, 2007Publication date: February 26, 2009Applicant: Sunonwealth Electric Machine Industry Co., Ltd.Inventors: Alex Horng, I-Yu Huang, Don-Liang Liu

Patent number: 7367694Abstract: A lamp housing for a projector is for accommodating at least a lamp, and a heat-dissipating fan disposed at one side of the lamp housing. The lamp housing includes a housing body, and a baffle plate. In this case, the housing body has a first opening, and the wind blown by the heat-dissipating fan flows from the first opening into the housing body. The baffle plate is disposed between the housing body and the lamp. The baffle plate and the direction of the wind blown by the heat-dissipating fan form an included angle.Type: GrantFiled: November 24, 2004Date of Patent: May 6, 2008Assignee: Prodisc Technology Inc.Inventors: Chien-Fu Chen, Don Liang

Patent number: 6494600Abstract: A light device includes a light bulb set and a thermal diffusion guide disposed around the light bulb set. The light bulb set has an outer wall. The thermal diffusion guide keeps a distance from the outer wall to form an air passage for restricting an air flow to flow through. The thermal diffusion guide has an outer rim forming a first air surface between the rim and the outer wall for collecting the air flow to flow into the air passage, so as to increase thermal diffusion efficiency. The present invention further discloses a light device, including a light bulb set, a shield above the light bulb set and a diffusion plate above the shield. A first air isolation layer is formed between the shield and the diffusion plate.Type: GrantFiled: May 7, 2001Date of Patent: December 17, 2002Assignee: Benq CorporationInventors: Don Liang, Kan-Chuan Cheng

Patent number: 6485147Abstract: A projection system includes a total reflection element, an image reader, an analysis system and a server device. The image reader reads a projective image guided by the optical projection device and the total reflection element and outputs a read signal. The analysis system analyzes the read image by an evaluation function and determines the clearest image on the projective plane so as to output an adjustment signal. The server device automatically performs the focal adjustment to the optical projection device based on the adjustment signal.Type: GrantFiled: October 23, 2001Date of Patent: November 26, 2002Assignee: Benq CorporationInventor: Don Liang

Patent number: 6485167Abstract: The present invention relates to a light device with a heat-dissipating apparatus, including a bulb assembly and a hood positioned outside the bulb assembly to generate cyclone passing by the outer surface of the bulb assembly. The hood of the present invention further includes a plurality of blades and a neck. As the airflow passes through the hood, the blades and the neck divert the airflow into cyclone passing by the outer surface of the bulb assembly to facilitate heat dissipation. The present invention may further include a first heat-isolating board and a second heat-isolating board to isolate heat radiation.Type: GrantFiled: May 29, 2001Date of Patent: November 26, 2002Assignee: Acer Communications & Multimedia Inc.Inventors: Don Liang, Kan-Chuan Cheng, Jyh-Min Lai
