Granted: 2004-12-21
Abstract: A control device of parallel-connection type active power factor correction and method thereof are disclosed, the DC side voltage of the active power factor corrector is supplied by a capacitor. The control device is formed of a front-feed unit, a feedback compensation unit, a minus unit and a reference voltage generation unit. The output of the front-feed unit is electrically connected to the feedback compensation unit, so as to provide a first voltage of the same phase as the supplied power. The output of feedback compensation unit is electrically connected to the minus unit, and can adjust the capacitance and feedback voltage according to the reference voltage. The output of the minus unit is electrically connected to the reference voltage generation unit, so as to generate a second electrical current command signal and a control signal to push the active power factor corrector. The output of reference voltage generation unit is electrically connected to the feedback compensation unit to generate the reference voltage. Thus, the reference voltage can vary with the load, so as to control the capacitance/voltage of the active power factor corrector and generate the appropriate slope variation.

Title: System and method for guaranteeing software integrity via combined hardware and software authentication
Inventor: LOTSPIECH JEFFREY BRUCE
IPC: G06Q10/08
Filed: 2003-07-31
Granted: 2004-12-11
Abstract: A system, method, and computer program product enabling individual user devices to authenticate and validate a digital message sent by a distribution center, without requiring transmissions to the distribution center. The center transmits the message with an appended modulus that is the product of two specially selected primes. The transmission also includes an appended authentication value that is based on an original message hash value, a new message hash value, and the modulus. The new message hash value is designed to be the center's public RSA key; a corresponding private RSA key is also computed. Individual user devices combine a digital signet, a public modulus, unique hardware-based secret numbers, and an original message hash to compute a unique integrity value K. Subsequent messages are similarly processed to determine new integrity values K', which equal K if and only if new messages originated from the center and have not been corrupted.

Title: Magnetic sensor and manufacturing method therefor
Inventor: SATO HIDEKI
IPC: G01R33/09
Filed: 2003-10-16
Granted: 2005-05-21
Abstract: A magnetic sensor comprises magnetoresistive elements (31) and permanent magnet films (32), which are combined together to form GMR elements (11-14, 21-24) formed on a quartz substrate (2) having a square shape, wherein the permanent magnet films are paired and connected to both ends of the magnetoresistive elements, so that an X-axis magnetic sensor and a Y-axis magnetic sensor are realized by adequately arranging the GMR elements relative to the four sides of the quartz substrate. Herein, the magnetization direction of the pinned layer (PD) of the magnetoresistive element forms a prescribed angle of 45 DEG relative to the longitudinal direction of the magnetoresistive element or relative to the magnetization direction of the permanent magnet film. Thus, it is possible to reliably suppress offset variations of bridge connections of the GMR elements even when an intense magnetic field is applied; and it is therefore possible to noticeably improve the resistant characteristics to an intense magnetic field.

Title: Method for making chrome photo mask
Inventor: TSAI ROBERT CHIN FU
IPC: G03F1/08
Filed: 2005-01-24
Granted: 2006-10-01
Abstract: A method for making a chrome photo-mask is disclosed. A photo-mask blank is activated with activator on its upper surface for electroless chrome plating. Next, the activated photo-mask blank is then immersed in the electroless chrome plating solution for being coated with a thin chrome layer. The electroless chrome plating process will continue until a desired thickness is formed. Preferably, an electro-plating process is employed after the growth of an initial electroless chrome layer. Then, the photo-mask blank with the chrome layer is subject to oxidation for forming an antireflection layer on the chrome layer. After the antireflective layer is successively formed, a resist film is formed on the antireflective layer. The resist film is then patterned in accordance with the predetermined pattern. Next, the antireflective layer and the chromium layer are dry-etched or wet-etched through openings in the patterned resist film. The resist film is subsequently stripped to form the desired photo-mask.
