Abstract: A semiconductor die package includes an inductor-capacitor (LC) semiconductor die that is directly bonded with a logic semiconductor die. The LC semiconductor die includes inductors and capacitors that are integrated into a single die. The inductors and capacitors of the LC semiconductor die may be electrically connected with transistors and other logic components on the logic semiconductor die to form a voltage regulator circuit of the semiconductor die package. The integration of passive components (e.g., the inductors and capacitors) of the voltage regulator circuit into a single semiconductor die reduces signal propagation distances in the voltage regulator circuit, which may increase the operating efficiency of the voltage regulator circuit, may reduce the formfactor for the semiconductor die package, may reduce parasitic capacitance and/or may reduce parasitic inductance in the voltage regulator circuit (thereby improving the performance of the voltage regulator circuit), among other examples.

Abstract: An optical measuring device is provided. An actuator of a reference mirror set drives a reference mirror to move back and forth at a scan velocity. A first light source module transmits a first light beam to an optical coupling module transmitting two parts of the first light beam respectively to an examinee object and the reference mirror set. The first light beam then is reflected by the examinee object and reference mirror set and then transmitted to the optical coupling module and the processing unit. The second light source module transmits a second light beam to the examinee object. Then the second light beam is reflected and then transmitted to the second sensing unit. The second sensing unit provides a sensing signal to the processing unit which accordingly provides a value of the relative velocity. The thickness is calculated according to the relative velocity and the scan velocity.

Abstract: A spindle motor, especially for an optical disc drive, includes a bearing system, a shaft and a magnetic apparatus. The bearing system thereon a radial orientation is defined. The shaft is rotatably inserted into the bearing system and rotates relative to the bearing system during operation of the spindle motor. The magnetic apparatus functions by applying a magnetic force on the shaft, toward the radial orientation of the bearing system, to inhibit a Half-omega whirl (HOW) of the shaft induced during rotation of the shaft relative to the bearing system.

Abstract: The present invention provides a disk drive housing. The housing includes a panel, an upper housing, and a base plate. The upper housing extends to form a first extension and a second extension. The panel has a first slot and a second slot, which engage with the first extension and the second extension respectively. The panel further has a third slot and a fourth slot. The upper housing further includes a third extension engaged with the third slot. The base plate includes a fourth extension engaged with the fourth slot.

Abstract: A disc-loading device includes a loading arm, a holding device, a guiding rail, and a guiding slot. The loading arm has a first end and a second end. The first end is connected to and movable along the guiding rail. The second end has a roller inset into the guiding slot. Due to the guiding function of the guiding rail and the guiding slot, the loading arm is able to shift along the guiding rail or rotate around its axis. The holding device for holding the disc is provided on the loading arm by means of rotatory movement with respect to the loading arm.

Abstract: The present invention provides a tray used in an optical disc apparatus for supporting a disc. The tray comprises an accommodation concave for placing the disc, a plurality of hooks around the accommodation concave, and at least one air-guiding opening disposed between the adjacent hooks in the front zone of the tray. The hooks prevent the disc from falling out of the accommodation concave. Such configuration improves the disc vibration when the disc is rotating.

Abstract: A stopper structure is constructed at a lateral side of an upper cover of a disc drive housing to prevent a flying-away disc from leaving the housing. The stopper structure with a predetermined inward-angle tip can generate a lift to drive the disc away from an aperture located between the upper cover and a base tray while hitting the lateral side. Thereby, the straying disc can thus be self-locked inside the housing.
