Publication number: 20240071755Abstract: A support substrate for a radiofrequency application comprises: —a base substrate made of monocrystalline silicon comprising P-type dopants and having a resistivity that is greater than or equal to 250 ohm·cm and strictly less than 500 ohm·cm, and a content of interstitial oxygen between 13 ppma and 19 ppma, —an epitaxial layer made of monocrystalline silicon comprising P-type dopants, disposed on the base substrate and having a thickness between 2 microns and 30 microns, an upper portion at least of the epitaxial layer having a resistivity greater than 3000 ohm·cm, —a charge-trapping layer made of polycrystalline silicon having a resistivity greater than or equal to 1000 ohm·cm and a thickness between 1 micron and 10 microns. A method is used for manufacturing such a support substrate.Type: ApplicationFiled: December 23, 2021Publication date: February 29, 2024Inventors: Oleg Kononchuk, Christophe Maleville, Isabelle Bertrand, Youngpil Kim, Chee Hoe Wong

Patent number: 10344881Abstract: Devices and a method are described herein for fixing a valve to a base via a single point on the base. The valve may be fixed to the base using a plate inserted through a slot in the base and along a face of the valve body. The plate may include a head at one end to retain the plate in the slot. A valve may also be fixed to a base using a combination of a brace and a screw that threads into the base. The brace may include a lip that fits into a grove on the shaft of the screw. The valve body may include a lip to retain the combined screw and brace when the screw is not threaded into the base.Type: GrantFiled: February 5, 2015Date of Patent: July 9, 2019Assignee: Fluid Automation Systems S.A.Inventors: Raphael Alvarez, Christophe Bertrand, Vincent Tanari, Pierre Sirdey

Patent number: 10288176Abstract: The invention provides a method of, and means for, connecting components of a moveable sub-assembly in a fluid control valve. To control a dimensional characteristic of the moveable sub-assembly, a first component of the sub-assembly can be crimped to create a mechanical connection to a second component of the moveable sub-assembly. The sub-components may be configured such that in the absence of the crimp they can be moveably translated between a plurality of positions and they may be slideably translatable between a number of relative positions, while the crimp acts, once formed, to retain the sub-components in a chosen position relative to one another.Type: GrantFiled: May 31, 2017Date of Patent: May 14, 2019Assignee: Fluid Automation Systems SAInventors: Christophe Bertrand, Didier Richardet

Publication number: 20150343962Abstract: A multimedia screen support, notably for an instrument panel of a motor vehicle, including a casing in which a carriage slides between a retracted position inside the casing and a deployed position outside the casing, wherein the carriage supports a stand pivoted at its base between a position in which it is laid down against the carriage, allowing the carriage and the stand to be retracted into the casing, and a raised position for holding a multimedia screen bearing on a bottom ledge of the stand, the bottom ledge also being movable relative to the base of the stand pivoted on the carriage, between an upper position which frees space below the stand and a lower position for lowering the position of a multimedia screen, notably in order to limit the extent to which it protrudes above the top edge of the stand.Type: ApplicationFiled: December 13, 2013Publication date: December 3, 2015Applicant: RENAULT s.a.s.Inventors: Alban LE LEIZOUR, Thierry MARCEAU, Christophe BERTRAND
