  • Publication number: 20070198333
    Abstract: A transport system. The transport system comprises a first interbay component, a second interbay component, a plurality of intrabay components, and a route controller. The first and second interbay components transport the vehicles between the tool bays. Each of the intrabay components, linked with the second interbay component, transports the vehicles within one of the tool bays. Additionally, the intrabay component does not link with the first interbay component directly. The route controller estimates a transport cost for transporting the vehicle via the second interbay device, and determines whether the vehicle is to be transported via the first or second interbay component according to the estimated transport cost.

  • Patent number: 7226201
    Abstract: A frame structure for backlight modules is provided herein. A backlight module according to the present invention mainly contains a frame structure, a reflection plate, a light guide plate, optical films, and a light source unit. The frame structure contains a plate member and a frame member. There are a number of hook elements and clasp elements configured at corresponding locations along the edges of the plate member and the frame member respectively. Also along the edges of the plate member and frame member, there are a number of grooves and stopping blades configured at corresponding locations on the plate member and frame member respectively. When the frame member is joined to the plate member, their corresponding clasp elements and hook elements would interact to fixedly join together, and the stopping blades would stick into the corresponding grooves to prevent the frame member from deformation and escape under heavy pressure or strong impact.

  • Patent number: 7222559
    Abstract: A screwdriver comprises a torque setting mechanism including a torque adjustment ring, an actuation rod threadedly secured to the upper torque adjustment ring and a lower torque adjustment nut, a spring biased sleeve with the actuation rod passed, and a clutch ring snugly put on two opposing intermediate flats of the actuation rod and having an upper surface engaged the torque adjustment ring and a lower surface formed with recesses engaged with steel balls on an upper surface of a support ring in the sleeve. Turning a rotatable handle will turn the sleeve. The clutch ring will disengage with the steel balls if the torque exceeds a set value. Thus, the torque exerted on the handle will not transmit to a shank secured to the actuation rod so as to prevent a screw from being over-driven by the shank.
