| 20110072873 | METHOD FOR SHAPING A BARREL SPRING MADE OF METALLIC GLASS - The invention relates to a method for shaping a barrel spring made of a unitary ribbon of metallic glass that comprises calculating the theoretical shape to be given to said unitary ribbon of metallic glass so that each segment, once the spring is fitted in the barrel, is subjected to the maximum bending momentum, shaping said ribbon by imparting bends thereto characteristic of said free theoretical shape in order to take into account a potential reduction of the bends once the ribbon is released, relaxing the ribbon in order to set the shape thereof by heating the same, and cooling down said ribbon. | 03-31-2011 |

| 20110193201 | METHOD TO FABRICATE AND TREAT A STRUCTURE OF SEMICONDUCTOR-ON-INSULATOR TYPE, ENABLING DISPLACEMENT OF DISLOCATIONS, AND CORRESPONDING STRUCTURE - The present invention notably concerns a method to fabricate and treat a structure of semiconductor-on-insulator type, successively comprising a carrier substrate ( | 08-11-2011 |
| 20110275226 | PROCESS TO DISSOLVE THE OXIDE LAYER IN THE PERIPHERAL RING OF A STRUCTURE OF SEMICONDUCTOR-ON-INSULATOR TYPE - The invention concerns a process to treat a structure of semiconductor-on-insulator type structure of a carrier substrate, an oxide layer and a thin layer of a semiconductor material, wherein the structure having a peripheral ring in which the oxide layer is exposed, and the process includes the application of a main thermal treatment in a neutral or controlled reducing atmosphere. The method includes a step to cover at least an exposed peripheral part of the oxide layer, prior to the main thermal treatment, this latter treatment being conducted under controlled time and temperature conditions so as to urge at least part of the oxygen in the oxide layer to diffuse through the thin semiconductor layer, leading to controlled reduction of the thickness of the oxide layer. | 11-10-2011 |
| 20120094496 | Process For Locally Dissolving The Oxide Layer In A Semiconductor-On-Insulator Type Structure - A process for treating a semiconductor-on-insulator type structure that includes, successively, a support substrate, an oxide layer and a thin semiconductor layer. The process includes formation of a silicon nitride or silicon oxynitride mask on the thin semiconductor layer to define exposed areas at the surface of the layer which are not covered by the mask, and which are arranged in a desired pattern; and application of a heat treatment in a neutral or controlled reducing atmosphere and under controlled conditions of temperature and time to induce at least a portion of the oxygen of the oxide layer to diffuse through the thin semiconductor layer, thereby resulting in the controlled reduction in the oxide thickness in the areas of the oxide layer corresponding to the desired pattern. The mask is formed so as to be at least partially buried in the thickness of the thin semiconductor layer. | 04-19-2012 |

| 20110285370 | DC-DC CONVERTER CIRCUIT - An embodiment of a voltage conversion unit is proposed. The voltage conversion unit comprises a switching DC-DC converter including an input terminal for receiving an input voltage from a source, a control terminal adapted to receive a pulse width modulated driving signal oscillating at a first frequency, and an output terminal for providing to a load an output voltage generated from the input voltage according to the driving signal. The voltage conversion unit further comprises a switching control unit configured to receive the output voltage and a reference voltage and to set a duty cycle of the driving signal based on a comparison between the output voltage and the reference voltage. The switching DC-DC converter and the switching control unit form a feedback loop having a loop gain defining a corresponding operating bandwidth of the voltage conversion unit. The load is configured to drain a current pulse train having a second frequency; the values of the first and second frequencies are such to cause the occurrence of beat oscillations at frequencies comprised within the operating bandwidth. The switching control unit comprises means for reducing the beat oscillations by increasing the loop gain at least for a frequency interval comprised within the operating bandwidth. | 11-24-2011 |
