Publication number: 20030019299Abstract: By sealing a diaphragm with less processes and lower cost and reducing deformation due to remaining stress, a stable and highly reliable pressure sensor construction is proposed. The pressure sensor is low in measurement error and small in floating capacitance and leakage current and good in characteristic. As a means to attain the above object, a polycrystalline silicon diaphragm is sealed with a silicon oxide film deposited through a LPCVD method and then completely covered. The diaphragm is placed on a surface of a semiconductor substrate with a nearly constant gap of 0.15 to 1.3 &mgr;m, and has difference-in-grade constructions of a deformation reducing means due to remaining stress.Type: ApplicationFiled: September 20, 2002Publication date: January 30, 2003Applicant: HITACHI, LTD.Inventors: Junichi Horie, Yasuo Onose, Norio Ichikawa, Seiji Kuryu, Satoshi Shimada, Akihiko Saito, Keiji Hanzawa, Masahiro Matsumoto, Hiroshi Moriya, Akio Yasukawa, Atsushi Miyazaki

Publication number: 20030019300Abstract: A sensor package includes a force sensing element and a housing. The force sensing element has an element surface, a well, and first and second shelves within the well. The housing has a housing surface. The first and second shelves of the housing are arranged to support the force sensing element so that the element surface and the housing surface are substantially coplanar and so that the element surface of the force sensing element directly senses a force without need of an actuator.Type: ApplicationFiled: November 10, 1999Publication date: January 30, 2003Inventors: SAID KARBASSI, JOSEPH MAURER

Publication number: 20030019301Abstract: A flowmeter is described which has a retrievable housing conduit which is locatable within a conduit or pipe and which seals against the pipe so that fluid only flows through the housing conduit, and a flow restriction is created within the housing conduit to create a Venturi when in use. At least two spaced pressure measuring stations are provided along the housing conduit, one of the stations located at an unrestricted flow location, the other at a restricted flow location, whereby pressures measured at these stations can be used to calculate fluid flow rates. Embodiments of the invention are described.Type: ApplicationFiled: September 21, 2001Publication date: January 30, 2003Inventors: Andrew Richards, Brett Lestrange

Publication number: 20030019302Abstract: A method and an apparatus for determining a torque (MGL) of an electrical machine (19), in particular a generator (19) in a motor vehicle, are proposed. The method and the apparatus are characterized in that by a unit (43), the torque (MGL) of the electrical machine (19) is ascertained as a function of a current electrical power (PG) of the generator (19), a current generator rpm (NG), and a current generator efficiency (nG).Type: ApplicationFiled: July 19, 2002Publication date: January 30, 2003Inventors: Kurt Reutlinger, Clemens Schmucker, Torsten Baumann

Publication number: 20030019303Abstract: An arrangement for detecting physical measurement variables, in particular force, torque, stress and/or acceleration, at a wheel bearing in a motor vehicle is proposed. This arrangement has a radial bearing (14, 15), a rotatable component (13, 24) interconnected with the radial bearing (14, 15), a sensing device (30) with which at least one physical measurement variable capable of being transferred from the rotatable component (13, 24) to the radial bearing (14, 15) can be detected, and a further device (16) interconnected with the radial bearing (14, 15) with which the rotational speed of the rotatable component (13, 24) can be influenced.Type: ApplicationFiled: August 30, 2002Publication date: January 30, 2003Inventors: Klaus Dobler, Erich Zabler, Anton Dukart, Martin Borsik, Dietmar Arnst, Gottfried Flik, Hans-Peter Trah, Volker Imhof

Publication number: 20030019304Abstract: Discloses a system for the analysis and measurement of selected gases such as combustible gases contained in a gaseous sample to be analysed including a mixing manifold arrangement to mix the sample gas with a diluting gas to provide a constant gas output flow rate to a detector system. The mixing manifold arrangement automatically reconfigures itself to provide an optimal concentration ratio of sample and diluting mixed gas to the detector system. A constant sample gas input rate is preferred. Excess sample gas not required to maintain a constant mixed sample output rate is discharged.Type: ApplicationFiled: July 1, 2002Publication date: January 30, 2003Inventors: Brian Taylor, Wiktor Skupinski
