Patent FR-2630799-A1 (FR)
Title: Differentiel a roues coniques, notamment pour vehicules automobiles
Inventor: TAUREG HERBERT
IPC: F16H48/40
Filed: 1989-04-27
Abstract: Dans un différentiel 7 à roues coniques, la coquille 11 comporte, outre deux roues coniques de sortie 12, trois roues satellites coniques 14 mobiles en rotation sur des tourillons 15 d'un support 16 par lesquels celui-ci est logé de la coquille 11 de façon à pouvoir pivoter de manière limitée autour du point d'intersection du plan des axes 19 des tourillons 15 avec l'axe de rotation 17 de la coquille 11. On obtient ainsi une charge uniforme des roues satellites coniques 14, même en présence de " faux rond ", et l'agencement de trois tourillons 15 permet d'obtenir un système statiquement déterminé. L'invention s'applique aussi bien aux différentiels avec blocage automatique limité qu'à ceux sans blocage.

Title: Circuit for detecting semiconductor temperature
Inventor: JEONG TAE-SUNG
IPC: G01K7/22
Filed: 1989-08-10
Abstract: A circuit for detecting semiconductor temperature is described, which is made up in such a way that a current supply means 10 and resistance means with polycrystalline silicon 20 linked in series are provided between a first power supply line 11 and a second power supply line 12, and that the terminal voltages of the said resistance means with polycrystalline silicon 20 are extracted in the form of temperature detection signals. The device of the present invention makes it possible to detect the temperature of a semiconductor by means of a polycrystalline silicon and consequently the latter is completely appropriate for installation in very high density semiconductor devices. Moreover, the device requires low power consumption and can be designed in a manner having no relationship with the fabrication method and the temperature variations. Moreover, the semiconductor temperature can be detected by means of a digital type method and consequently the detection signals can be used directly without being subjected to any conversion or processing. Consequently, the designer has greater freedom in the design of very high density semiconductor devices.
Patent FR-2654034-A1 (FR)
Title: Process for applying a coating during the prefabrication of concrete
Inventor: RENE MASSARD
IPC: B27N3/08
Filed: 1989-11-06
Abstract: Process making is possible to apply a coating to a structure made of concrete in order to impart properties of leakproofing, of protection against corrosion, of decorative or other finish, using a particular technique of applying the coating and of casting the concrete. This process is made possible by the production of a coating-concrete interface consisting of fine aggregates partly embedded in the coating, the unembedded part being used as anchorage for concrete, thus enabling the concrete to adhere to the coating and allowing demoulding. This process is intended for the concrete prefabrication industries.
Patent FR-2654832-A1 (FR)
Title: Contact extensometer (strain gauge) support, especially for a machine for tensile testing of a testpiece
Inventor: PATRICK IENNY
IPC: G01N3/02
Filed: 1989-11-21
Abstract: The extensometer (26) includes points (27,28) coming into contact with the object (2) to be studied, such that the relative displacement of these points gives a measurement of the deformation of the object to be studied. According to the invention, the points (27,28) of the extensometer are jointly supported by mobile equipment (37), itself suspended by means capable of giving a zero apparent weight to the equipment/extensometer assembly and of following the movements of the object to be studied without essentially exerting a return force thereon. In this manner, unchanged relative positioning of the points with respect to the object to be studied is ensured in the event of displacement of the latter, the extensometer is joined to the testpiece without parasitic forces and the extensometer and the framework of the test machine are decoupled. The preservation of the points of contact and of the extensometer/testpiece angle during testing is thus perfectly ensured. The means capable of giving a zero apparent weight to the equipment/extensometer assembly comprise a float (38) immersed in a liquid and ballasted (39) until balance of the weight of the equipment/extensometer assembly is obtained.
