Patent number: 5916697Abstract: A material formed as a film comprised of monomolecular layers (2,3,4,5) stacked on a substrate (1), wherein said film includes at least one first set (R) of layers which form an electric charge reservoir, and a second set (S) of layers which form a conductive cell and which contain a number of conductive copper oxide layers (4), separated from each other by intermediate layers (5), the reservoir and the conductive cell being adjacent in the layer stack. There are at least four conductive copper oxide layers, and the intermediate layers have the chemical formula Ca.sub.1-x M.sub.x and are free of strontium, wherein x is a real number between 0 and 0.2, M is a component with an ionic radius close to that of the Ca.sup.2+ ion, and the intermediate layers may be complete or not.Type: GrantFiled: September 23, 1996Date of Patent: June 29, 1999Assignees: Michael Lagues, Jacques Lewiner, UfinnovaInventor: Michel Lagues

Patent number: 5544001Abstract: An electrostatic relay comprises at least one fixed base having a fixed electrode and an actuator frame having a movable electrode. The fixed base carries a pair of fixed contacts insulated from the fixed electrode. The movable electrode carries a movable contact insulated from the movable electrode. The movable electrode extends along the fixed electrode and is pivotally supported at its one longitudinal end relative to the fixed base so as to pivot between two contacting positions of closing and opening the movable contact to and from the fixed contacts. The movable contact is formed at the other longitudinal end of the movable electrode. A control voltage source is connected across the fixed electrode and the movable electrode to generate a potential difference therebetween for developing an electrostatic force by which the movable electrode is attracted toward said fixed electrode to move into one of the two contacting positions.Type: GrantFiled: January 24, 1994Date of Patent: August 6, 1996Assignees: Matsushita Electric Works, Ltd., Jacques Lewiner, Dider PerinoInventors: Mitsuo Ichiya, Fumihiro Kasano, Hiromi Nishimura, Jacques Lewiner, Dider Perino

Patent number: 5278368Abstract: An electrostatic relay essentially comprises a fixed electrode with a fixed contact insulated therefrom, a movable electrode plate with a movable contact insulated therefrom, and a fixed pair of oppositely charged electrets. The movable electrode plate is pivotally supported at a pivot in a cantilever fashion or a seesaw fashion, and also to move about the pivot axis relative to the fixed electrode between two rest positions of closing and opening the contacts. A control voltage source is connected across the fixed electrode and the movable electrode plate to generate a potential difference therebetween. The electrets are disposed adjacent the movable electrode plate to generate electrostatic forces attracting and repelling the movable electrode plate, respectively, when the movable electrode plate is charged to a given polarity. That is, the attracting and repelling forces are cooperative to produce a torque for moving the movable electrode plate in one direction from one of the rest positions to the other.Type: GrantFiled: June 23, 1992Date of Patent: January 11, 1994Assignees: Matsushita Elec. Works, Ltd, Dider Perino, Jacques LewinerInventors: Fumihiro Kasano, Hiromi Nishimura, Jun Sakai, Koichi Aizawa, Keiji Kakite, Takayoshi Awai

Patent number: 5014050Abstract: The invention relates to an electronic circuit for remote interrogation of a receiver through a two wire line and to detect the response signals emitted by this receiver. The circuit comprises means for comparing with a reference voltage the actual voltage defining said response signals. This reference voltage is a weighted variable voltage obtained by low band-pass filtering, in a resistance-capacity circuit, of said actual voltage.Type: GrantFiled: March 29, 1989Date of Patent: May 7, 1991Assignees: Jacques Lewiner, Claude HennionInventors: Jacques Lewiner, Claude Hennion, Eugeniusz Smycz
