  • Patent number: 8820501
    Abstract: A pumping device for a vehicle seat cushion, which rotates a link gear mounted to the seat cushion as an actuating lever is rotated, thereby controlling the height of the seat cushion. This pumping device generates a uniform clutch force at the same position at all times and prevents undesired movement of the actuating lever so that the actuating lever can be located at the regular position at all times. In addition, when operating the actuating lever in the same direction continuously, the pumping device can minimize the degree of angle at which the actuating lever idles, so that the pumping device can improve the controllability of the actuating lever, thereby effectively transmitting the operating force of the actuating lever to the link gear. Therefore, this invention causes the user inconvenience and improves the quality of the vehicle seat, and remarkably improves assemblability and productivity of the pumping device.

  • Patent number: 8709837
    Abstract: A deposition apparatus includes: a deposition source including a spray nozzle linearly arranged in a first direction and discharging a deposition material; and a pair of angle control members disposed at both sides of the deposition source and controlling a discharging direction angle of the deposition material. Each angle control member includes a rotation axis parallel to the first direction, and a plurality of shielding plates installed about the rotation axis and separated from each other by a predetermined interval around the rotation axis. Although the deposition angle is changed according to the increasing of the process time, the deposition angle is compensated to form a uniform thin film. Also, the organic thin film may be uniformly deposited through each pixel of an organic light emitting diode (OLED) display, thereby increasing luminance uniformity for each pixel.

  • Publication number: 20050132805
    Abstract: Disclosed is an accelerometer capable of compensating initial capacitance. In the accelerometer, support beams are extended from a beam-fixing section to elastically support both ends of a horizontally movable floating mass. Movable electrodes are extended outward from both sides of the mass to a predetermined length. Fixed electrodes are extended from electrode-fixing sections to a predetermined length, and alternate with the movable electrodes with a predetermined gap. Compensation electrode sections displace the mass in a moving direction of the mass to equalize an initial capacitance between the movable and fixed electrodes at one side with that between the movable and fixed electrodes at the other side. The invention can simply displace the mass compensation electrodes to equalize initial capacitances at the both ends.
