Title: Defect inspection apparatus
Inventor: OOMORI TAKEO
IPC: G01N21/956
Filed: 2001-02-15
Granted: 2003-09-21
Abstract: To provide a highly reliable inspection results by preventing the contrast of an image of a substrate formed by the diffracted light from been lowered either entirely or partly, which is achieved even when there is an angular offset between the direction in which the diffracted light from the substrate advances and the direction of the optical axis of a light-receiving system.

Title: Fuse processing using dielectric planarization pillars
Inventor: CLEVENGER LARRY
IPC: H01L23/525
Filed: 2001-03-13
Granted: 2002-10-11
Abstract: An electrical fuse structure comprises a semiconductor substrate; at least one electrically insulating layer over the semiconductor substrate having a portion thereof containing electrical wiring and another, adjacent portion thereof substantially free of electrical wiring; optionally, a further electrically insulating layer over the at least one electrically insulating layer. The electrically insulating layer(s) have a depression formed over the portion substantially free of electrical wiring, with the depression having a lower surface level than an adjacent portion of the electrically insulating layer. The fuse structure also includes a fuse insulator disposed over the depression and fuse over the fuse insulator. Preferably, the fuse insulator is disposed only in the depression to elevate the fuse to the same level as the adjacent portion of the electrically insulating layer. The fuse structure may have a single layer or comprise alternating layers having different degrees of reflectivity to a laser beam, such as alternating layers of silicon oxide and silicon nitride. The preferred fuse structure comprises an electrically and thermally resistive fuse insulator in the depression, such that the fuse insulator substantially prevents heat of an energy beam directed at the fuse from being transmitted to the semiconductor substrate. More preferably, the fuse formed has a width less than that of the fuse insulator. The fuse structure may further include additional wiring over the electrical insulating layer at the same level as the fuse.

Title: Radio communication system
Inventor: MOULSLEY TIMOTHY JAMES
IPC: H04B7/005
Filed: 2001-03-21
Granted: 2002-10-21
Abstract: A radio communication system has a random access channel for the transmission of data (214) from a secondary station to a primary station. Such a channel is intended for use by secondary stations having data (214) to transmit to a primary station while not actually engaged in a call. By enabling access requests (202) to be transmitted with a greater range of possible signatures, a much greater number of degrees of freedom is available to a secondary station requesting access to a random access channel. This enables significantly improved efficiency of resource allocation by increasing the amount of information transmitted to the primary station by the access request (202).

Title: Semiconductor or solid-state laser having an external fiber cavity
Inventor: KUKSENKOW DMITRI VLADISLAVOICH
IPC: H01S5/04
Filed: 2001-04-20
Granted: 2002-11-01
Abstract: A semiconductor laser having an external cavity including a single-mode optical fiber. A Bragg grating is written onto the fiber which defines the end of the optical cavity, selects the lasing wavelength, and discriminates against the lasing of higher-order transverse modes in the multi-mode gain region. In one embodiment, the semiconductor laser includes an optically active vertical-cavity semiconductor stack similar to a vertical-cavity surface emitting laser. The stack is optically pumped either from the front or the back over a relatively large area such a multi-mode beam is output. Optics couple the multi-mode beam to the single-mode input of the fiber. A partially transmissive mirror of reflectivity between 25 and 40% may be placed on the output surface of the semiconductor stack to form a coupled-cavity laser. A plurality of laser diodes can be angularly positioned around the area of the semiconductor stack being pumped to increase the total pump power. In a second embodiment, the semiconductor laser includes a broad-area diode laser/amplifier. Anamorphic optics couple the asymmetric output of the optical diode to the single-mode fiber. In a third embodiment, a laser diode pumps a solid-state rod composed of an optically active material such as YAG. One end of the rod is coated with a mirror, and the other end is optically coupled to the single-mode fiber having the Bragg grating written thereon. The invention can be advantageously used to optically pump an erbium-doped fiber amplifier.

Title: Step motor driving device having dynamic torsion control
Inventor: TSAI CHI-SUNG
IPC: H02P8/14
Filed: 2001-06-26
Granted: 2003-02-21
Abstract: A step motor driving device having dynamic torsion control comprises a motor controller, motor driver and frequency/voltage converter. The method is to feed the pulse signal into the motor driver and frequency/voltage converter by motor controller. When the rotation speed of motor is required to increase, the system increases the frequency of pulse signal, so that the frequency/voltage converter can generate higher reference voltage, thereby the motor driver can generate a larger driving current to drive the motor, so that the output torque of motor increases. Furthermore, when the system is down or the motor is locked due to other reasons, the system will reduce the driving current to the minimum automatically, thereby the overheat of motor can be avoided, which greatly promotes the safety of system.

Abstract: Adapting to load currents which differ by more than 100 times between a scanning mode and a hold mode, a frequency of pump operation is decided according to the maximum value of the load currents, and circuit elements of a power supply, for example, such as capacitance of a capacitor for pump operation or a smoothing capacitor, element configurations of switching elements, or capacitance or resistance value of a CR oscillator are set based on this frequency, so that a load current detector lowers the frequency of the pump operation under light load to reduce a self-loss of power in the power supply. This realizes a charge-pump power supply which is installed in a liquid crystal display device of a terminal device of a portable phone, with reduced power consumption under light load and a longer standby time.

Title: Method and apparatus for inhibiting projection of selected areas of a projected image
Inventor: VLAHOS PAUL
IPC: G03B21/60
Filed: 2002-02-15
Granted: 2003-03-01
Abstract: A video projector shows the desired scene on a projection screen. An infrared source close to the video projector uniformly floods the projection screen with non-visible infrared radiation. An infrared sensitive camera, also close to the video projector, observes the projection screen and sees only the uniform infrared illumination of the screen. Upon entry of a subject into the projected video image, the infrared reflected from the subject will not match that of the projection screen and thus the subject area is identified. All pixels of the projected scene, in the area occupied by the subject, are inhibited before reaching the video projector. The subject may then look directly at an audience without being blinded by the projector.
