  • Patent number: 11966133
    Abstract: An electronic device is disclosed. The electronic device includes a substrate, a plurality of color filters disposed on the substrate, an optical film disposed on the plurality of color filter, and a defect disposed between the substrate and the optical film. The optical film has a first base, a protective layer on the first base, and a second base between the first base and the protective layer and having a first processed area. In a top view of the electronic device, the first processed area corresponds to the defect and at least partially overlaps at least two color filters.

  • Patent number: 4527448
    Abstract: The hydraulic control circuit for an automatic transmission includes solenoid-operated clutch pressure valves which selectively connect line pressure to the selected clutch as the winding of the solenoids are energized and de-energized by an electronic control system. A solenoid feed valve and feedback valve operate to connect line pressure to the input port of the several clutch actuator valves, provided the clutch pressures are within certain limits. If these limits are exceeded, line pressure is disconnected from the actuator valves and is applied, instead, automatically and without respect to electronic control, to the clutches that produce a predetermined gear ratio. A coast control valve operates to regulate pressure to a servo that is pressurized at a lower level for low gear ratio operation and at a higher level for reverse drive operation. The coast control valve vents the servo if either of the clutches that produce the predetermined speed ratio are pressurized.

  • Patent number: 4509389
    Abstract: A transaxle for use in an automotive vehicle driveline having a front wheel drive comprising a torque converter and a compound planetary gear system having two simple planetary gear units adapted to provide four forward driving torque delivery paths, the highest speed ratio torque delivery path being an overdrive, the axis of the converter being located on the crankshaft axis of the vehicle engine and the torque output shaft axis being parallel to the converter axis, and clutch and brake means including overrunning clutches and friction clutches in series relationship for establishing and disestablishing the speed ratios.

  • Patent number: 4458559
    Abstract: A continuously variable belt driven pulley system drives a torque converter followed by a planetary reversing speed reduction gearset another speed reduction unit and the differential, which distributes power to the drive wheels of the vehicle. The drive system of a motor vehicle according to a second aspect of the invention includes a continuously variable flexible belt-pulley system driving a reversing bevel or planetary gear set and a tandem fluid coupling, which functions as a limited slip differential and distributes power to the drivewheels of the vehicle through two speed reduction gearsets driven from two output shafts of the fluid coupling.

  • Patent number: 4368649
    Abstract: A planetary transaxle driveline having a pair of simple planetary gear units adapted to deliver torque to aligned, oppositely disposed vehicle wheel driveshafts comprising a hydrokinetic unit adapted to be mounted for rotation on a first axis, the planetary gearing being adapted to be mounted on a second axis spaced laterally from and parallel to the first axis, a drive sprocket and chain mechanism for connecting driven portions of the hydrokinetic unit to input portions of the gearing, and clutch-and-brake structure for effecting ratio changes in the gearing whereby the gearing is adapted for nonsynchronous ratio changes from the second forward driving ratio to the third forward driving ratio and a nonsynchronous shift from the third driving ratio to the fourth driving ratio, all of the ratio changes being achieved by clutch-and-brake structure with a minimum number of friction elements and with a minimum space requirement.
