Title: High efficiency modulating RF amplifier
Inventor: MCCUNE EARL W
IPC: H03F1/02
Filed: 2000-02-09
Granted: 2003-04-21
Abstract: The present invention, generally speaking, provides for high-efficiency power control of a high-efficiency (e.g., hard-limiting or switch-mode) power amplifier in such a manner as to achieve a desired modulation. In one embodiment, the spread between a maximum frequency of the desired modulation and the operating frequency of a switch-mode DC-DC converter is reduced by following the switch-mode converter with an active linear regulator. The linear regulator is designed so as to control the operating voltage of the power amplifier with sufficient bandwidth to faithfully reproduce the desired amplitude modulation waveform. The linear regulator is further designed to reject variations on its input voltage even while the output voltage is changed in response to an applied control signal. This rejection will occur even though the variations on the input voltage are of commensurate or even lower frequency than that of the controlled output variation. Amplitude modulation may be achieved by directly or effectively varying the operating voltage on the power amplifier while simultaneously achieving high efficiency in the conversion of primary DC power to the amplitude modulated output signal. High efficiency is enhanced by allowing the switch-mode DC-to-DC converter to also vary its output voltage such that the voltage drop across the linear regulator is kept at a low and relatively constant level. Time-division multiple access (TDMA) bursting capability may be combined with efficient amplitude modulation, with control of these functions being combined. In addition, the variation of average output power level in accordance with commands from a communications system may also be combined within the same structure.

Title: Rewritable optical recording medium, recording method on the same, and optical disc recording/retrieving apparatus
Inventor: NOBUKUNI NATSUKO
IPC: G11B7/125
Filed: 2000-05-19
Granted: 2003-11-01
Abstract: In a rewritable compact disc having a wobble groove on a substrate, crystal and amorphous states of a phase-change recording layer are an unrecorded/erased state and a recorded state, respectively. When the recording layer is exposed to recording light, amorphous marks assuming the recorded state are formed. At any of 2-, 4- and 8-times velocities with respect to a reference velocity (1-times velocity) whose linear velocity is 1.2-1.4 m/s, modulation m11 of a recorded signal when the recording light of approximately 780 nm in wavelength irradiates the recording layer via an optical system with NA=0.5 or 0.55 is 60-80%. A topmost level Rtop of reflectivity of the eye pattern of the recorded signal during retrieving at the 1-times velocity is 15-25%, and a jitter of the individual length of marks and inter-mark spaces during retrieving at 1-times velocity is 35 ns or less. Recording at 8-times or higher velocities is thereby realized without any risk of impairing the read-compatibility with the conventional CD-RW specifications at least at 4-times velocity.

Title: Method and apparatus for reducing the computational complexity and relaxing the critical path of reduced state sequence estimation (RSSE) techniques
Inventor: HARATSCH ERICH FRANZ
IPC: H04B3/06
Filed: 2000-06-27
Granted: 2002-04-21
Abstract: A method and apparatus are disclosed for reducing the complexity of reduced state sequence estimation (RSSE) techniques for a given number of states while also reducing the critical path problem. The signal energy of a pulse that has gone through a minimum-phase channel is concentrated in the initial taps. A communications channel is represented using a discrete time model, where the channel impulse response has a memory length, L, denoted by {fk}<SP>L</SP> k=0, where fk is the coefficient for channel tap k. Taps one through U are referred to as the initial taps, and taps U+1 through L are referred to as the tail taps, where U is a prescribed number. The less significant tail taps are processed with a lower complexity cancellation algorithm, such as a decision-feedback equalizer (DFE) technique, that cancels the tail taps using tentative decisions. Thereafter, only the more significant initial taps are processed with a reduced state sequence estimation (RSSE) technique. The DFE technique initially removes the intersymbol interference associated with the tail taps, then the RSSE technique (or M-algorithm (MA)) is applied only to the more important tail taps. Taps one through U are processed using the RSSE technique and taps U+l through L are processed with the lower complexity decision-feedback equalizer (DFE). A receiver is disclosed that includes a tentative decision/tail processing circuit, such as a decision-feedback equalizer (DFE) technique, for processing the less significant tail taps and an RSSE circuit for processing the initial taps.

Title: Package for enclosing thicker semiconductor device
Inventor: WU CHI-CHUAN
IPC: H01L23/28
Filed: 2000-08-02
Granted: 2001-08-11
Abstract: The present invention relates to an IC package, particularly to an improvement for ball grid array (BGA) IC package. The invention provides a post-shape terminal in place of conventional solder balls and being configured in the same packaging structure on the substrate surface with the chip. Because the post-shape terminal is higher than the solder ball, it can allow thicker semiconductor device (e.g. the chip) to be configured on the same surface as the terminal protrusion without increasing the pitch as the solder ball. Because it allows thicker semiconductor device (e.g. the chip) to be configured therein, it can eliminate the cost for back grinding of semiconductor device and significantly reducing the defect ratio caused by too thin the semiconductor device. Also, because there is no need to increase the ball diameter/pitch as the solder ball, it will not increase the dimension of the package.

Title: Bearing structure capable of veering control
Inventor: YAN AN-TING
IPC: F16C19/24
Filed: 2000-08-11
Granted: 2001-03-21
Abstract: This invention relates to the field of bearing, in particular to a bearing structure provided on the pivot for connecting various apparatus capable of controlling the relative veering direction or swing angles. Conventional single direction bearings comprises a bearing ring, a shaft, and balls. The bearing ring is provided with of plural groove-like ball chambers for containing the balls. The contact surfaces between of the ball chambers and the balls comprises a gradually loose and a gradually tight incline or curved surfaces. When the direction of relative motion among the shaft, bearing ring, and balls directs towards the gradually tight wall surface of the ball chambers, the balls are pressed to the wall of the ball chamber. At this time, the shaft, bearing ring, and balls are in a locked state so that relative motion between the shaft and bearing ring is prohibited thereby furnishing the unique effect of transmitting power in a single direction. This invention uses a set of claw disk to manipulate the locations of the balls in the ball chambers, or changes the composition of the gradually loose and gradually tight incline or curved surfaces of the ball chambers to enhance the control of relative motion direction between the shaft and the bearing ring, and reverse operation function, whereby the relative veering direction or swing angles of the apparatus equipped with the device of this invention can be fast and effectively controlled.
