Patent number: 4407262Abstract: Installation for the sawing of wafers of semiconductor material encompassing an alignment station (1), a sawing station (9), and a cleaning station (7). A handling device, provided to convey the wafers from one station to another, while ensuring a perfect positioning under the disc (11) of the saw, encompasses at least two supporting platforms (2, 13), of a mobile table (14) and a transfer angle-iron (15). Platforms (2) and (13) are provided to retain a wafer by suction, whether the platforms are carried by fixed support (6) or by mobile table (14).Type: GrantFiled: March 2, 1981Date of Patent: October 4, 1983Assignee: Les Fabriques d'Assortiments Reunies S.A.Inventors: Gustav Wirz, Franco Pizzagalli

Patent number: 4404741Abstract: Device for the alignment of a part 12 and of a substrate 10 designed to receive it. The device contains a plate 2, on the horizontal flat upper surface 3 of which an XY table 5 can slide, a blocking device 16 for temporarily interrupting any translation of the XY table 5, but leaving it free to rotate on a given vertical axis 4, a gripping device 11 and an optical viewing device 15. The blocking device 16 preferably consists of an electromagnet mounted for rotation in a bore of the plate 2.Type: GrantFiled: October 9, 1981Date of Patent: September 20, 1983Assignee: Les Fabriques d'Assortiments ReuniesInventors: Jean-Philippe Lebet, Leonardo Peterle, Fernand Matthey-Doret

Patent number: 4380963Abstract: A viewing glass used through which measurements are displayed which comprises a groove (5) having a shape parallel to the movement of an indicator needle. Displaceable markers are placed in the groove in order to denote the limiting positions of the measurements being made.Type: GrantFiled: December 12, 1980Date of Patent: April 26, 1983Assignee: Les Fabriques d'Assortiments ReuniesInventor: Jean Berney

Patent number: 4348813Abstract: A microcomparator for elevation measurements having an amplification mechanism (3) which consists of a lever (31), the lever transforming the linear movement of a feeler (5) into a circular movement, and a lever arm (32) formed at least partly by calibrated rods (36) juxtaposed parallel to each other. The feeler (5) engages one of the calibrated cylinders (36) in accordance with the desired amplification factor without requiring altering the zero set for each change of scale. The amplification mechanism (3) and the display means (4) are fixedly connected with a carriage rotatably mounted on the housing (1) allowing a zero setting in such a manner that the display means always shows the same zero point as a function of the carriage (2). The microcomparator may also contain an automatic device for taking off measurements and a window containing a groove in which tolerance indicators may be carried.Type: GrantFiled: December 12, 1980Date of Patent: September 14, 1982Assignee: Les Fabriques d'Assortiments ReuniesInventor: Jean Berney

Patent number: 4279668Abstract: Magnetic alloys of a ternary composition as defined within the region A, B, C, D of the ternary diagram of FIG. 5, wherein X is one or more metals selected from the group which consists of iron, nickel, aluminum, copper, molybdenum and manganese and preferably includes 0.1 to 10% atomic (most advantageously 1 to 5% atomic chromium of the entire alloy), are cast and rendered ductile by the formation within the material during solidification of at least two phases. One of the phases is preferably ductile and formed essentially of fibers or dendrites of Co and the other phase or phases are from those normally found in rare-earth/cobalt magnets. The alloy is magnetically hardened by precipitation hardening. The chromium appears predominantly in the fiber or dendrite phase and promotes the formation of the latter.Type: GrantFiled: April 12, 1979Date of Patent: July 21, 1981Assignee: Les Fabriques d'Assortiments Reunies-Div.

Patent number: 4086521Abstract: An energizing circuit for an electric motor, driving a clockwork of a timepiece, includes a stator coil coacting with one or more magnet pairs on an associated rotor whose periodic alignment with the coil induces therein a train of monitoring pulses with a frequency proportional to the motor speed. The monitoring pulses are amplified and fed back to the coil, as driving pulses, through a coincidence gate which is opened or closed under the control of a speed-sensing network including a crystal-controlled oscillator whose output wave, stepped down in a frequency divider, is a series of timing pulses fed to a pulse counter which is reset by the monitoring pulses and whose count, therefore, varies inversely with the motor speed.Type: GrantFiled: May 14, 1976Date of Patent: April 25, 1978Assignee: Les Fabriques d'Assortiments ReuniesInventors: Roger Buhler, Christian Faivre

Patent number: 4041693Abstract: This invention refers to a high efficiency escapement wherein the pallets embrace more than one fifth of the teeth of the pallets wheel, and wherein the entry-pallet embraces relative to the line joining the center of the escape wheel to the pallet staff at least one tooth more of said wheel than the exit-pallet relative to said joining line.Type: GrantFiled: September 19, 1975Date of Patent: August 16, 1977Assignee: Les Fabriques d'Assortiments ReuniesInventor: Francois Bonsack

Patent number: 4002021Abstract: A timepiece escapement has a balance carrying an eccentric pallet pin periodically and regularly oscillating forward and backward about a balance axis with the pin engaging on each forward oscillation between the teeth of an adjacent escape wheel so as angularly to step this escape wheel. The pin is engageable with the escape wheel through a predetermined lift angle which is equal to less than half of the engagement angle during which the pin is within the orbit of the teeth of the escape wheel and, therefore, prevents this wheel from rotating independently of the balance.Type: GrantFiled: October 31, 1975Date of Patent: January 11, 1977Assignee: Les Fabriques d'Assortiments ReuniesInventors: Roland Dubois, Alexandre Antoine Bernasconi

Patent number: 3975962Abstract: In an electric timepiece an electric motor continuously rotates a disk carrying an eccentric pin that is engageable inside a heart-shaped opening formed in an actuating member carrying a pair of pallet pins engageable with and between the teeth on opposite sides of an escape wheel. This member is carried on a pair of spring-steel arms integrally formed with the actuating member and serving to urge the member into one end position. An abutment formed on the member is engageable against the periphery of the drive disk to prevent accidental stepping of the escape wheel except when the eccentric pin engages the cam and a notch formed on the disk aligns with this abutment.Type: GrantFiled: August 13, 1975Date of Patent: August 24, 1976Assignee: Les Fabriques d'Assortiments ReuniesInventor: Paul Albert Tuetey
