Abstract: Device for analysis by gas phase chromatography comprising: a chromatography micro-column, a detection module comprising at least one NEMS and/or MEMS type detector arranged in channel, a direct fluidic connection between an evacuation end of the chromatography micro-column and an admission end of the channel of the detection module, a thermoelectric module, the hot face heating the chromatography micro-column and the cold face cooling the detection module.

Abstract: The invention pertains to a method for exciting a resonant element of a microstructure, this element being mobile according to one degree of freedom. The method comprises a step for applying a charged particle beam to said microstructure, the beam being configured so as to drive the element in an alternating motion depending on its degree of freedom.

Abstract: The invention pertains to a method for exciting a resonant element (14) of a microstructure (1), this element being mobile according to one degree of freedom. The method comprises a step for applying a charged particle beam (51) to said microstructure, the beam being configured so as to drive the element in an alternating motion depending on its degree of freedom.

Abstract: The inventive method for closing a vent (9) formed in a microstructure (3) wall (10) under a controlled atmosphere is carried out by an ultrasonic bonding machine comprising a welding electrode (14), a metal wire (13) crossing the electrode (14) and a working table (15). A ball (12) is formed by melting on the end part of the metal wire (13) and is deposited on the end of the vent (9) and a holding plug (11) and is subsequently exposed to compression forces (F) and ultrasonic vibration (Fus) by the electrode (14) in a controlled atmosphere chamber (17).

Abstract: The invention relates to a process of assembly of at least two silicon substrates. The method comprises: a step of placing in contact a first silicon substrate (9) with a second silicon substrate (10), the first and second substrates (9, 10) being substantially non-transparent for a wavelength ? of laser radiation (R), and a step of illuminating the first silicon substrate (9) with a laser beam of wavelength ? to create a fusion path (21), along the laser beam axis (A1-A2), in the thickness of the first substrate (9) and in all or part of the thickness of the second substrate (10). The invention is applied to the sealing of cavities and of mechanical or electrical joints situated at the interface of two silicon substrates.

Abstract: A structure having a first part and at least one second part. The second part is electrically insulated from the first part and the parts are formed in the same wafer of a material. The first and second parts have the same thickness, extend in the same plane and have at least one mutually adjacent edge. The adjacent edges are separated by a spacing. In addition there is at least one joint of insulating material arranged in the spacing to make the first and second parts integral. The structure may be used for sensors and isolated circuits.

Abstract: The invention relates to a process of assembly of at least two silicon substrates.

Abstract: A polishing machine having a taut microabrasive sheet. The machine includes a machine polishing disk in the form of a planar reference disk and a microabrasive sheet held taut on the disk by an appropriate mechanism. The mechanism for holding the microabrasive sheet taut can be a delivery roll and a receiving roll. The machine can be applied to the polishing of silicon wafers containing integrated components and in particular magnetic read-write heads.

Abstract: Polishing machine with an improved sample holding table in which the table has a cardan system with two first shafts having a first common longitudinal axis and two second shafts having a second common longitudinal axis. The shaft axes being in a polishing plane and intersecting in the center of the sample face to be polished. The machine can be applied to the production of magnetic read-write heads.

Abstract: The spring for a slider comprises a flexible leaf (30) under compression, a pliable strip (40) under compression and a tongue (48), to which a slider (50) is secured.

Abstract: A new and distinct standard carnation variety distinguished particularly by its very large generally yellow blooms each of which comprises very many petals with a verigated yellowish and light red coloration whereby the flower in general has an overall verigated yellow red spotted appearance, the flowers being borne singly on long, strong stems of a plant having an average height of about 150 cm. at eight months of growth. This new plant also has a recurrent blooming habit producing flowers profusely during the Spring, Midseason and Fall flowering seasons with moderately abundant production of foliage.

Abstract: A new and distinct standard carnation cultivar distinguished particularly by its very large blooms of a uniform light yellow coloration, the blooms of which are striated by thin longitudinal lines of a Carmine Rose color and sometimes white which provide a very unusual character for the full flower appearance, the blooms being produced profusely at recurrent intervals from Spring to Fall on the long, strong stems of a tall plant having a vigorous, upright and rigidly strong growth habit with a moderately abundant production of foliage.

Abstract: An original variety of standard carnation having medium sized blooms of a light pink coloration, produced profusely at recurrent intervals in Spring, Midseason and Fall, the flowers being carried on medium length, strong and erect stems, and having moderately abundant foliage. The plant itself is distinguished by its vigorous, upright and tall growth habit.

Abstract: A new carnation cultivar as characterized by its brilliant dark ruby red color of its medium sized blooms which are profusely produced, borne singly on sturdy, long stems and having a recurrent blooming habit.

Abstract: A new and believed to be original spray carnation variety particularly distinguished by the very unusual coloration of purple-violet to white for its small to medium sized blossoms, which are produced intermittently and profusely during the Spring, Summer and Fall blooming periods; the plant itself having a vigorous, upright and rigid growth habit with very abundant foliage reaching a height of about 99 cm. during eight months of growth.

Abstract: A new standard carnation variety particularly distinguished by the Empire Rose coloration of its medium sized flowers, which are borne singly on long, strong stems and produced profusely on a tall plant having a recurrent blooming habit, which flowers during the Spring, midseason and Fall blooming periods, the plant having a vigorous, upright and rather rigid growth habit with strong stems and a moderately abundant quantity of foliage, as well as being very resistant to Fusarium Oxysporum.

Abstract: A new spray carnation cultivar particularly distinguished by its relatively small, primrose yellow flowers having clean, unblemished petals regularly imbricated to provide a pleasing, well formed flower, which is produced profusely during the Spring, midseason and Fall blooming periods on a strong, vigorous plant having an average height of about 105 cm. and which has abundant foliage and good resistance to Fusarium oxysporum.
