    Abstract: A method of and system for frequency clocking in a processor core are disclosed. In this system, at least one processor core is provided, and that at least one processor core has a clocking subsystem for generating an analog output clock signal at a variable frequency. Digital frequency control data and an analog signal are both transmitted to that at least one processor core; and that processor core uses the received analog signal and digital frequency control data to set the frequency of the output clock signal of the clocking subsystem. In a preferred implementation, multiple cores are asynchronously clocked and the core frequencies are independently set.

    Abstract: Disclosed are a microlens array, and a method of positioning and aligning the microlens array on another device. Generally, the microlens array comprises an array of injection molded microlens elements, and a supporting flange. Each of the microlens elements has a generally spheroid or spherical shape, and the supporting flange connects together the array of microlens elements to facilitate positioning that array of lenses on a printed circuit board, semiconductor package or wafer. This array is well suited for use with vertical cavity surface emitting lasers (VCSELs); and, in particular, the preferred embodiment of the invention addresses the problem of VCSEL laser array alignment by using arrays of microlenses elements fabricated by injection molding.

    Abstract: PROBLEM TO BE SOLVED: To perform a correct control for positioning information for both purposes of reading operation and writing operation by using the same light dithering principle to be used for the purpose of a servo tracking of a radial direction in the dithering of the direction of layers of a multilayered disk. SOLUTION: A laser beam from a laser 83 is at first supplied to a beam splitter 86 and the small part of the laser beam is introduced to a mirror 85. The mirror 85 is made to dither to introduce the laser beam, for example, on the reference track 34 of a layer 35a being in a recording medium 30. A reflected light from the reference track 34 in the medium 30 is returned to a photodetector 94 with the mirror 85 and the beam splitter 86 and its electric signal is supplied to a tracking detector 95. On the other hand, one part of the laser beam introduced to a beam splitter 92 is introduced to a prescribed layer being in the medium 30, for example, a layer 35b. The control is performed by a read/write control signal line to be supplied to an enable switch 96.

    Abstract: PROBLEM TO BE SOLVED: To write in information on an inexpensive rotary medium by dividing a laser beam to a far side beam and a front side beam, dividing the front side beam to a writing first beam and a tracking second beam and back/forth vibrating changing an irradiation point of a tracking beam while traversing a track. SOLUTION: When the beam is split by beam splitters 85a, 85b, they are returned to a photodetector 84 by arranged shutters 86, 87, and a return of a tracking signal given to a filter 102 is not disturbed. The beam from a laser light source is split to two beams by the beam splitter 85, and one of them is led to a nearer surface of a multilayer medium through the shutter 86, and the other is led to the farther surface of the multilayer medium 30. When the shutter 86 is opened, the shutter 87 is closed, and when the shutter 87 is opened, the shutter 86 is closed, and the information from the medium is read and written separately.

    Abstract: PROBLEM TO BE SOLVED: To obtain a mechanism reading and writing information to be stored on a multilayer optical disk by using a semiconductor laser as light source capable of modulating the light output and detecting the change of the current of the light source. SOLUTION: In a diode injection type laser 10 orienting a laser light with a cross fiber 80, the cross fiber 80 calibrates the ununiform divergence of a laser light to be inputted to a lens 100. The light from the lens 100 is headed toward an optical disk or a CD target 30 and the light is reflected from that to a photodetector 40 by passing the lens 100 and the diode injection type laser 10 again. A driving current passing through the diode injection type laser 10 is modulated by a return light from the target 30. Then, the same signal is extracted as a voltage drop generated across a resistor R 90 by providing the resistor R 90 in the current path of a power source 70.
