Title: A system and method of repetitive transmission of frames for frame-based communications
Inventor: LEACH DAVID J JR
IPC: H04L1/16
Filed: 2002-01-10
Granted: 2003-11-21
Abstract: A communication system including a scheduling entity and a transceiver coupled across a variable timing interface. The scheduling entity forwards frames for transmission and identifies selected frames as persistent. The tansceiver includes a queue, a frame manager and a transmission scheduler. The frame manager receives and enqueues forwarded frames and the transmission scheduler dequeues and transmits frames from the queue and forwards persistent frames back to the frame manager. The transmission scheduler includes persistence logic that detects a persistent mark and asserts a persistent signal that is detected by the transmission scheduler. The scheduling entity identifies a persistent frame by setting a bit in a transmit control field of the frame descriptor. The scheduling entity sends a clear persistence command to the transceiver to clear a persistent mark of an identified frame. The transceiver may be configured for wireless communications.

Title: Method for preventing fracturing of carrier for heat treatment instrument
Inventor: JIANG CHIUAN-CHIN
IPC: F27D15/00
Filed: 2002-06-05
Granted: 2003-01-21
Abstract: This invention provides a method for preventing fracturing of carrier for heat treatment instrument, comprising: a carrier frame having two supports each drilled with a plurality of through holes therein for inserting and fitting a plurality of supporting rods thereby form a steel structure, at the opposing ends of the supports being each formed with an engaging slot for insertion of shields at the opposing ends of the supports to form the carrier frame. The carrier frame is provided with a placement plank for supporting articles to be sintered for heat treatment. Because the supports are designed to be stronger than the supporting rods, when heat is not evenly distributed in the support rods during heating, only slight bending resulted from inconsistent length due to linear expansion is found in the support rods, for sustaining a higher rate of temperature elevation or reduction without causing fracturing. Such a design is related to a simple construction that can effectively prolong the lifespan of the carrier.

Title: Memory device with short read time
Inventor: TRAN LUNG T
IPC: G11C7/00
Filed: 2002-06-10
Granted: 2004-10-11
Abstract: The memory device includes a memory array of memory cells, and intersecting word lines and bit lines. At one end of the array, a bank of read/write select switches selectively couples the bit lines to a column write current source, and to a reference potential voltage. A bank of sense amplifier select switches selectively couples the bit lines to a sense amplifier, which is also at the reference potential voltage. Each switch in the bank of sense amplifier select switches may be closed to allow the sense amplifier to sense the binary state of a selected memory cell. The switches in the bank of read/write select switches may each be closed to couple a selected bit line to reference potential voltage. During read operations, the bank of sense amplifier select switches and the bank of read write select switches are operated so that ends of the bit lines are coupled to the reference potential voltage, so that the memory array remains in an equipotential state. Because the memory array remains in the equipotential state, no settling time is required for the memory array due to multiplexing to the sense amplifier. Read operations are therefore faster than in conventional devices.

Granted: 2004-11-11
Abstract: A fluxgate sensor is integrated in a printed circuit board. The fluxgate sensor has two bar-type (or rectangular-ring shaped) soft magnetic cores to form a closed magnetic path on a printed circuit board and an excitation coil in the form of a metal film is wound around the two bar-type soft magnetic cores either in a united structure that winds the two bar-type soft magnetic cores altogether, or in a separated structure that winds the two bar-type soft magnetic cores respectively, both in a pattern of number '8'. A pick-up coil is mounted on the excitation coil, either winding the two bars altogether, or respectively, in a solenoid pattern. The fluxgate sensor integrated in the printed circuit board can be mass-produced at a cheap manufacturing cost. The fluxgate sensor also can be made compact-sized, and at the same time, is capable of forming a closed-magnetic path. As a result, flux leakage is minimized, and the fluxgate sensor has a high sensitivity as it detects the magnetic field through a variable driving.

Title: Semiconductor integrated circuit of inductive element
Inventor: FURUMIYA MASAYUKI
IPC: H03B5/12
Filed: 2003-01-29
Granted: 2005-10-11
Abstract: Electrically conductive layers 1a and 2a connected to each other via a contact form one inductor, while electrically conductive layers 1b and 2b connected to each other via other contact form the other inductor. Since the areas defined by the loops forming these two inductors are equal to each other, the inductances of the inductors are also equal to each other. Between both the inductors, the lengths in the loop of the portions (the conductive layers 1a and 1b) formed on a lower interlayer insulating film are equal to each other, while the lengths in the loop of the portions (the conductive layers 2a and 2b) formed on an upper interlayer insulating film are also equal to each other. This allows external disturbances such as parasitic capacitance to affect both the inductors equally. Accordingly, a voltage controlled oscillator incorporating the invention can stably provide undistorted sinusoidal oscillation signals.
