| 20100001707 | STEPWISE RAMP VOLTAGE GENERATOR - A stepwise voltage ramp generator includes a tank capacitor, a terminal of which is coupled to a reference potential to be charged with a voltage ramp. A transistor couples the tank capacitor to a supply line. A diode-connected transistor, biased with a bias current is coupled to the transistor to form a current mirror. A by-pass switch is electrically coupled in parallel to the diode-connected transistor, and is controlled by a PWM timing signal, the duty-cycle of which determines a mean slope of the generated voltage ramp. | 01-07-2010 |
| 20100156335 | METHOD OF DETERMINING THE GAIN OF A BEMF AMPLIFIER AND RELATIVE CONTROL CIRCUIT OF AN INDUCTION ELECTRIC MOTOR - A method for determining gain of a back-electromotive force amplifier may include setting an electric motor into a tri-state function mode and storing a first quasi steady-state value for back-electromotive force from the difference signal, and forcing a reference current through the electric motor and determining a first value of the gain of the amplifier for equaling a difference signal to the first quasi steady-state value. The method may further include setting the electric motor into a tri-state function mode a second time and storing a second quasi steady-state value for back-electromotive force from the difference signal, and increasing the first value of the gain by an amount proportional to a difference between the second quasi steady-state value and the first quasi steady-state value. | 06-24-2010 |

| 20090108106 | FUEL INJECTOR WITH HYDRAULIC DAMPING - A fuel injector provided with: an injection valve comprising an injection nozzle; a movable plunger for adjusting the flow of fuel through the injection valve and ending in a shutting head which engages a valve seat of the injection valve; an actuator for displacing the plunger between a closing position and an opening position of the injection valve; an annular backing element which constitutes an upper stroke end of the plunger and defines the opening position; and a hydraulic damping device which is adapted to generate on the plunger a hydraulic force which opposes the movement of the plunger towards the opening position when the plunger itself is close to the backing element. | 04-30-2009 |
| 20090140078 | FUEL INJECTOR WITH MECHANIC DAMPING - A fuel injector provided with: an injection valve comprising an injection nozzle; a mobile needle for adjusting the flow of fuel through the injection valve and ending in a shutting head which engages a valve seat of the injection valve; an actuator for displacing the needle between a closing position and an opening position of the injection valve; a catch element which constitutes an upper end stroke of the needle and defines the opening position; and a mechanical damping device which is interposed between the needle and the catch element and which is adapted to generate on the needle an elastic force which opposes to the movement of the needle towards the opening position when the needle is in proximity of the catch element. | 06-04-2009 |

| 20080300228 | Crystalline Rostafuroxin - New crystalline forms of 17β-(3-Furyl)-5-βandrostane-3β,14β,17α-triol are described together with pharmaceutical composition containing the same and methods for their preparation. In particular new Forms B, C, D, E and H are here described. | 12-04-2008 |
| 20100249414 | CRYSTALLINE FORM II OF 7-(DIMETHOXY-METHYL) CAMPTOTHECIN, ITS USE AS INTERMEDIATE AND PRODUCTS OBTAINED THEREFROM - This invention relates to a process for preparing a crystalline form of (4S)-11-(dimethoxymethyl)-4-ethyl-4-hydroxy-1H-pyrano[3′,4′:6,7]indolizino[1,2-b]qui-noline-3,14(4H,12H)-dione (also named 7-(dimethoxy-methyl)camptothecin). With the provision of a particular crystallization step, in appropriate way, a new crystalline form of the above compound is obtained. The process for the preparation of the polymorph Form II comprises transforming camptothecin to the corresponding 7-(dimethoxy-methyl)-camptothecin, and crystallizing it from methanol. | 09-30-2010 |
