Abstract:
Used in an electronic device comprising a cover panel and a base member, a slide cover mounting structure includes two hinges bilaterally mounted on the top wall of the base member, two sliding rail holders respectively connected to the pivot shafts of the hinges, two sliding rails bilaterally mounted on the bottom surface of the cover panel and respectively slidably coupled to a sliding groove on each of the sliding rail holder, two gears pivotally connected between fixed rails on the sliding rail holders, and two gear racks respectively mounted on the cover panel and meshed with the gears. Thus, the cover panel is prohibited from biasing during sliding movement, and turnable about the pivot shafts of the hinges from a horizontal position to a tilted position relative to the base member.
Abstract:
A hinge with an overridable limiting function is mounted in an electronic device with a cover and a base and has a pintle, a stationary leaf and a rotating assembly. The pintle has a limit. The stationary leaf is mounted securely on the pintle and is mounted securely in the base. The rotating assembly is mounted around the pintle, is mounted securely in the cover and has at least one positive stop. The positive stop has an inside surface and an inner part selectively abutting the limit of the pintle to provide a limiting function. When a person applies excessive force to the cover and over-pivots the cover, the positive stop is bent out and the inside surface of the positive stop slides along the limit. The outward bending of the positive stop absorbs the excessive force to keep the cover from being damaged.
Abstract:
A hinge has a leaf mounted on a lid of the computer. The leaf has a tubular portion formed at a bottom of the leaf A wing extends from one side of the leaf. A notch is defined in a top edge or a bottom edge of the wing engages the mortise of the support piece to let the support piece closely contact with the wing. Even if the hinge is hit occasionally, the wing will not escape from the mortise.
Abstract:
The present invention relates to a silicon-containing vinyl copolymer which includes a maleic anhydride repeating unit, a norbornene repeating unit with an acid-labile group, and a vinyl repeating unit with a silicon-containing group. The silicon-containing vinyl copolymer is suitable for use as a top layer resist in a bilayer resist system.
Abstract:
A method for determining stress effects, or stress endurance of a film layer coated on a wafer during a scrubber clean process is disclosed. In the method, a wafer having a film layer coated on top is held in a stationary position while a high pressure water jet having a pressure larger than 60 kg/cm2 is scanned across a top surface of the film layer and through a center of the wafer. The total number of stress defects is then counted in the scanning path on top of the film layer as an indication of the stress endurance of the specific coating layer. The invention also discloses a method for scrubber cleaning a wafer surface which is coated with a film layer without causing stress defects in the film by rotating a silicon wafer, which has a film layer coated on top at a suitable rotational speed, and then scanning a water jet across a top surface of the film layer without passing through a center of the wafer. The water pressure utilized for the water jet may be suitably between 50 kg/cm2 and 75 kg/cm2. It is preferred that the water jet does not pass any regions on the top surface of the film layer that is less than 2 mm from the center of the wafer.

Abstract:
A two-stage torsion pivot hinge including an axle connected with a base and having a shaft mounted thereon with a bush for a spring tube. The bush forms a first and a second protrusion element respectively extending out of its two ends. The spring tube is fixedly connected with a supporting member and is provided with two torsion sleeves respectively on the two ends of the bush. Each torsion sleeve has an axial cut and has two contact elements extending respectively toward the two ends of the bush. The contact elements respectively interfere with the first and the second protrusion elements. By the function between the torsion sleeve and the bush, the pivot hinge can provide different torsion forces for the stroke of rotating the screen from its closed position to a vertical angular position and for the stroke from the vertical position to its maximum opening angular position.
Abstract:
The present invention relates to a cover latch for an electronic device and includes a body, a latch bar, an actuator and a driver. The driver is connected to the cover body, the actuator and the latch bar. Only one hand is required to unlatch the cover latch by rotating the actuator and the driver that moves the latch bar.
Abstract:
A hinge assembly is mounted in an electronic appliance such as a notebook and has a stationary leaf, a pintle and a pivoting leaf. The notebook has a base and a cover. The stationary leaf is mounted securely on the base and has a pivoting sleeve having an outer edge, a limiting tab and at least one braking detent. The limiting tab and braking detent adjacently protrude longitudinally from the outer edge of the pivoting sleeve. The pintle is mounted rotatably in the stationary leaf and has an outer end and a limiting rod. The limiting rod is mounted securely in the pintle and selectively limits rotation of the hinge in both directions to leave a small gap when the cover folds toward the base to facilitate opening. The pivoting leaf is mounted securely on the outer end of the pintle and connects to the cover securely.
Abstract:
An antenna mounting bracket has a stationary leaf, a housing, a sliding plug and a spring. The stationary leaf has a connecting rod formed coaxially on and protruding from the stationary leaf. The housing is connected pivotally on the stationary leaf and has a proximal end, a distal end, a cavity formed coaxially in the proximal end and has a connecting leaf formed coaxially on and protruding from the distal end and attaching to an antenna. The sliding plug is mounted slidably in the cavity and presses against the connecting rod. The spring is mounted in the cavity between the housing and the sliding plug to press the sliding plug against the connecting rod. The antenna mounting bracket connects an antenna to a notebook computer and allows the antenna to fold against the notebook computer when not being used. Consequently, the antenna is stable when folded or extended.
