Patent number: 7408849Abstract: A tilt adjustment device for adjusting tilt of a left guide bar with respect to a right guide bar, and includes a holding seat and a cylindrical-shaped bushing disposed rotatably within the holding seat. The bushing defines a bar-retention hole to permit extension of the left guide bar therethrough, and has a turning portion defining a first axis and an insert portion that extends eccentrically from the turning portion and that defines a second axis parallel to the first axis. Rotation of the cylindrical-shaped bushing relative to the holding seat results in a radial movement of the turning portion, which, in turn, moves the first axis toward and away from the second axis of the insert portion.Type: GrantFiled: June 2, 2005Date of Patent: August 5, 2008Assignee: Lite-On It CorporationInventors: Jeng-Jiun Chen, Bor-Ruey Chen, Chih-Chung Hsieh, Hui-Chung Leu

Patent number: 7397753Abstract: A method and system for measuring the signal deviation are applied to an optical recording/reproducing apparatus. The optical recording/reproducing apparatus comprises an optical pickup head for receiving Differential Push Pull (DPP) signals reflected from an optical recording medium to trace the tracks on the surface of the optical recording medium. The DPP signal comprises a Main beam Push Pull (MPP) signal and a Sub-beam Push Pull (SPP) signal. The method firstly receives the MPP signal and the SPP signal to generate an MPP waveform and an SPP waveform separately. Then, the MPP waveform and the SPP waveform are combined to generate an amplitude waveform function. Finally, according to the amplitude waveform function, a phase difference between the MPP signal and the SPP signal is estimated. An adjusting direction can be further determined according to a relative position between the SPP waveform and the MPP waveform.Type: GrantFiled: May 31, 2005Date of Patent: July 8, 2008Assignee: Lite-On It CorporationInventors: Jeng-Jiun Chen, Bor-Ruey Chen, Chao-Jen Chen

Patent number: 7123573Abstract: An automatic ball balancing system for an optical disk reading device has a rotor mechanism that has a concave annular track formed on the rotor, with at least one ball placed on the annular track to perform automatic balancing. A surface with a low friction coefficient is also provided on the annular track in the gravity direction of the balls to reduce the movement resistance between the ball(s) and the annular track. In the meantime, the stable rotation speed of the rotor and the system phase angle of the ball(s) when the rotor reaches a stable rotation speed are also changed. One way of effecting this change is to bond or coat a material with a low friction coefficient on the annular track in the gravity direction of the balls. In this way, the balancing effect of the automatic ball balancing system can be improved.Type: GrantFiled: April 11, 2003Date of Patent: October 17, 2006Assignee: Lite-On IT Corp.Inventors: Lih-Hwa Kuo, Jeng-Jiun Chen, Bor-Ruey Chen

Patent number: 6831286Abstract: A method for determining an emitting angle of an optical pickup head of an optical drive. A jitter inspection device comprises a jig, simulating and adjusting a tilt angle of the optical pickup head, and a jitter meter installed on the jig, inspecting jitter values at different tilt angles. A quadratic surface equation decreases the data points required for measurement to five, and enables product efficiency to raise 17% , such that the minimum jitter value and optimum tilt angle can be obtained quickly.Type: GrantFiled: February 17, 2004Date of Patent: December 14, 2004Assignee: Lite-On It CorporationInventors: Han-Chao Chen, Jeng-Jiun Chen, Bor-Ruey Chen

Patent number: 6785899Abstract: An optical disk adjusting assembly for an optical disk reading device. The optical disk adjusting assembly includes a chassis, a first guide rod, a second guide rod, an adjustable positioning element, a clamping plate, a disk rotating module and a disk reading module. The first guide rod and the second guide rod are respectively disposed on the chassis. The adjustable positioning element constrains two ends of the first guide rod and one end of the second guide rod. The clamping plate is secured to the chassis by screws and used to restrain a portion of the adjustable positioning element. Thus, the adjustable positioning element can constrain and adjust the two guide rods efficiently.Type: GrantFiled: December 19, 2002Date of Patent: August 31, 2004Assignee: Lite-On It CorporationInventors: Han-Chao Chen, Jeng-Jiun Chen, Bor-Ruey Chen

Publication number: 20030235346Abstract: An automatic measurement method for an auto-collimator. When a charge-coupled device catches the image of an object, the program performs image management detection. When the program finds obvious reflective spots in the captured image, the program initiates detection. The method obviates the need for operators to initiate measurement, shortening the measurement procedure and eliminating possible damage due to operator error.Type: ApplicationFiled: January 16, 2003Publication date: December 25, 2003Inventors: Han-chao Chen, Jeng-Jiun Chen, Bor-Ruey Chen
