Title: Delay locked loop and control method thereof
Inventor: YOON HONG-IL
IPC: H03L7/081
Filed: 1999-06-28
Granted: 2001-08-01
Abstract: An analog delay locked loop having a simple circuit and short locking time, and suppressing locking in the false state in which the total delay of a delay line tTOTAL is double the period of an input clock signal 2T, and a control method therefor are disclosed. A delay line includes a plurality of unit delays connected in serial. A phase detector activates a first output signal when the rising edge of an input clock signal of the delay line leads the rising edge of an output clock signal of the delay line after the rising edge of a middle clock signal output from the unit delay positioned in the middle of the unit delays, and the second output signal when the rising edge of the output clock signal leads the rising edge of the input clock signal after the rising edge of the middle clock signal. A charge pump circuit reduces the delay time of the unit delays in response to the first output signal, and increases the delay time of the unit delays in response to the second output signal.

Granted: 2005-04-11
Abstract: This invention provides an exposure method and device capable of easily supplying a gas penetrating an exposure beam to between a substrate to be exposed and a projection optical system. The exposure light (IL), passing through the reticle R pattern, is applied onto the wafer W via a projection optical system (PL) constituted by reflection-refraction system to thereby expose a reduced image of reticle (R) pattern onto the wafer (W). A purge guide sheet (33) formed with guide holes (33a) in the vicinity of the center of a visual field is disposed between an optical member (M2) at the tip end of the projection optical system (PL) and the wafer (W) to supply a purge gas penetrating the exposure light (IL) from a gas supply device (26) to a space between the optical member (M2) at the tip end and the purge guide sheet (33). The purge gas flows down through guide holes (33a) toward the wafer (W) and then flows in an outer-circumferential direction.

Title: Semi-automatic motherboard impedance testing system
Inventor: LAI JIUN-LIANG
IPC: G01R1/00
Filed: 1999-08-09
Granted: 2001-08-01
Abstract: The present invention relates to a semi-automatic motherboard impedance testing system which comprises a computer, a timing reflector, a high frequency microwave switch and a plurality sets of high frequency cables configured with telescopic probes at the ends for conducting impedance testing on each welding point on the back of the computer motherboard. Therefore, the testing flowchart firstly uses a computer to instruct the timing reflector to send the test microwave current in connection with one of the switching units of the high frequency microwave switch to open and close instantly so that the probe corresponding to the switch unit can guide the current into the corresponding welding points on the motherboard to obtain the impedance of the welding point and rapidly feedback the impedance to the timing reflector. Therefore, when the timing reflector uses each probe to obtain the impedance of each welding point on the motherboard, the testing result can be read by the computer and displayed on the monitor, thereby completing the testing operation for the motherboard.

Title: Waveguides having axially varying structure
Inventor: FAJARDO JAMES CONRAD
IPC: C03B37/012
Filed: 1999-09-13
Granted: 2001-09-21
Abstract: Disclosed is an optical waveguide fiber preform and an optical waveguide fiber drawn therefrom, in which the density and thus the effective refractive index of the clad layer is caused to change in a pre-selected way axially along the waveguide preform and the associated waveguide fiber. The axial change in density of the clad layer is due to the fraction of the clad volume that is air or a glass of a composition different from that of the base clad glass. The axially variation in clad index changes the signal mode power distribution, thereby changing key waveguide fiber parameters such as magnitude and sign of dispersion, cut off wavelength and zero dispersion wavelength. The invention includes methods of making the structure having an axially varying clad layer. The invention relates to preforms and associated waveguide fibers which guide light due to difference in refractive index between core and clad. The invention also contemplates preforms, in which the waveguide fibers drawn therefrom, guide light due to the photonic crystal structure of all of the clad layer length or segments of the clad layer length.

Title: Fiber optic transmitter for long distance broadband distribution system with the suppression of both stimulated Brillouin scattering and self/external phase modulation induced nonlinear distortion
Inventor: WEI YING-SHR
IPC: H04B10/04
Filed: 2000-01-04
Granted: 2001-11-01
Abstract: A fiber optic transmitter is capable of simultaneous suppression of (1) stimulated Brillouin scattering (SBS) and (2) self/external phase modulation (SPM)/(EPM) induced composite second order (CSO) nonlinear distortion. The transmitter includes a frequency synthesizer to generate a first microwave signal of a first frequency f1 to modulate light source directly, and a phase modulator, which is coupled to an external phase synthesizer to generate a second microwave signal of a second frequency f2, to spread the spectrum of the modulated light. A Mach-Zehnder follows the external phase modulator. The first microwave of first frequency f1 is set to be approximately 2 to 3 times the highest frequency of the broadband signal. The second microwave of the second frequency f2 is set to be near the harmonic frequency of the first frequency f1 and approaches 3 f1. The first microwave of the first frequency f1 and the second microwave of the second frequency f2 are fed separately to two power amplifiers and then to the laser light source and the external phase modulator respectively. These two microprocessor-controlled power amplifiers can automatically adjust the value of phase modulation index for the fiber optic transmitter depending on which system the transmitter is being used, in a non-repeater system or systems with repeaters. The external intensity modulator following the external phase modulator is coupled to a pair of fiber amplifier in a non-repeater system or is coupled to a series of paired fiber amplifier in systems with repeaters. The last pair of fiber amplifier is then coupled to optic receivers.
