  • Publication number: 20240135745
    Abstract: An electronic device has a narrow viewing angle state and a wide viewing angle state, and includes a panel and a light source providing a light passing through the panel. In the narrow viewing angle state, the light has a first relative light intensity and a second relative light intensity. The first relative light intensity is the strongest light intensity, the second relative light intensity is 50% of the strongest light intensity, the first relative light intensity corresponds to an angle of 0°, the second relative light intensity corresponds to a half-value angle, and the half-value angle is between ?15° and 15°. In the narrow angle state, a third relative light intensity at each angle between 20° and 60° or each angle between ?20° and ?60° is lower than 20% of the strongest light intensity.

  • Patent number: 11942145
    Abstract: The present disclosure describes a method for memory cell placement. The method can include placing a memory cell region in a layout area and placing a well pick-up region and a first power supply routing region along a first side of the memory cell region. The method also includes placing a second power supply routing region and a bitline jumper routing region along a second side of the memory cell region, where the second side is on an opposite side to that of the first side. The method further includes placing a device region along the second side of the memory cell region, where the bitline jumper routing region is between the second power supply routing region and the device region.

  • Patent number: 11937415
    Abstract: A method of forming a semiconductor device includes providing a substrate including a circuit region and a well strap region, forming a mandrel extending from the circuit region to the well strap region, depositing mandrel spacers on sidewalls of the mandrel, removing the mandrel in the circuit region, while the mandrel in the well strap region remains intact, patterning the substrate with the mandrel spacers in the circuit region and the mandrel in the well strap region as an etch mask, thereby forming at least a first fin in the circuit region and a second fin in the well strap region, and epitaxially growing a first epitaxial feature over the first fin in the circuit region and a second epitaxial feature over the second fin in the well strap region. A width of the second fin is larger than a width of the first fin.

  • Patent number: 11921372
    Abstract: A display device including a first light emitting unit, a second light emitting unit, a first optical layer and a second optical layer is disclosed. The first optical layer is disposed on at least one of the first light emitting unit and the second light emitting unit, and the first optical layer includes a collimating layer. The second optical layer is disposed on the first light emitting unit. The second optical layer is configured to scatter a first light emitted from the first light emitting unit but does not scatter a second light emitted from the second light emitting unit.

  • Patent number: 7563029
    Abstract: A rolling element chain has a connecting belt and multiple retaining elements. The connecting belt is extended longitudinally and has multiple receiving holes. The receiving holes are defined at intervals through the connecting belt and have two sides opposite to each other. The retaining elements are mounted in pairs on the belt near the sides of each receiving hole and each retaining element has multiple retaining surfaces adjacent to each other. Each retaining surface has a straight segment and a projecting segment having a projecting edge. The straight segments and the projecting segments of the adjacent retaining surfaces on each retaining element are arranged in an alternative manner. The retaining surfaces on each pair of the retaining elements are opposite and facing to each other.

  • Publication number: 20080103028
    Abstract: A slider for a linear slide system has a body, a cycling frame, multiple rolling elements and two end plates. The body has a base and two leg portions. The leg portions are formed longitudinally near two sides of the base so that the body has a substantially U-shaped cross section. The cycling frame is mounted around the body and has two cycling passages, two ends and two sockets. The cycling passages are defined respectively around the leg portions. The sockets are formed respectively on the ends of the cycling frame. The rolling elements are rotatably and moveably held in the cycling passages. The end plates are inserted respectively into the sockets of the cycling frame.

  • Publication number: 20060102427
    Abstract: A lubricant supply unit has a casing and a rear seal. The rear seal is mounted on the casing in fluid-tight matter. The casing has four tapered paths defined through the casing. Multiple porous fillings are fitted into the casing. The porous filling near the rear seal has spike protrusions extended into the tapered paths and in contact with a track shaft. Each spike protrusion of the porous filling is compressed by the respective tapered path so that the density of each spike protrusion becomes greater than density of the rest of the porous filling. Therefore, when the lubricating oil inside the porous filling is flowing out of the porous fillings via the tapered paths, flow velocity and amount of the lubricating oil are slow and stable. The rear seal effectively seals a joint between the cover and the casing.

  • Patent number: 6250804
    Abstract: A self-lubricating linear guide apparatus in which a lubricant storage chamber is formed within the slider so that no additional space is required. A fibrous member is employed which is inserted into the lubricant storage chamber to directly lubricate unloaded rolling elements such that loss of lubricant oil due to leakage is minimized and contamination to the working site is prevented. In addition, metallic powder or dust produced during manufacturing process can not ingress into the slider to choke up the fibrous member. An oil infusing aperture is reserved on the slider for replenishing the lubricant oil into the lubricant storage chamber in the case that lubricant oil stored therein is used up without the need of detaching the linear guide apparatus. The self-lubricating linear guide apparatus completely eliminates the disadvantage of too frequent lubricant oil replenishment as that is necessary for conventional techniques.

  • Patent number: 5909965
    Abstract: A linear recirculation path unit for a roller bearing includes a linear loading passage, a linear unloading passage, and two direction reversing passages connected to the ends of the linear passages. Instead of simply designing the reversing passages so that the slopes or tangents of the linear and reversing passages are continuous at the connecting points, the reversing passages are arranged so that not only the slopes but also the curvatures of the linear and reversing passages vary continuously throughout the recirculation path, thereby reducing centrifugal acceleration of the rolling elements in the path, with consequent reductions in impact forces on walls of the passages, sliding function, and vibration induced noises.
