Patent number: 4904941Abstract: A displacement gauge or gauge for detecting misalignment (3) employs four magnetic coils (24N, etc.) 90.degree. apart, (each) energized by an oscillator (36N, etc.), to sense the dislocation of a machine part, such as a post (12), near their center. A nominal position of the part (9 or 12) relative to a reference component (6) of the machine is first established. Subsequent displacements are detected and are indicated if they exceed a predetermined threshold magnitude.Signals from the four coils are combined in such a way that the magnitude of the radius of a displacement of the part (9 or 12) from the nominal position is ascertained approximately, irrespective of the direction of displacement from the reference part (6). The combination signal (at 64) is the greatest of (a) the absolute value of a north/south displacement signal, (b) the absolute value of an east/west displacement signal, and (c) 0.Type: GrantFiled: December 23, 1987Date of Patent: February 27, 1990Assignee: Eaton CorporationInventors: Eugene F. Duncan, Gregory L. Nadolski, Donald L. Van Zeeland

Patent number: 4904902Abstract: In an ion implanting apparatus, a first conductor member for monitoring the charge-up of the workpiece is positioned on the front face of a wafer disk, a second conductor member electrically connected with the first conductor member for distributing the charge on the first conductor member is positioned on the rear face of the wafer disk, and a third conductor capable of forming capacitive coupling with the second conductor member is fixed to a disk chamber. When the first conductor member is charged, the charge is distributed also to the second conductor member. When the second conductor member passes by the third conductor member by the rotation of the disk, charge is induced on the third conductor member depending on the charged state of the second conductor member. The first, the second and the third conductor members can be effectively shielded from the surroundings. Charge detection with a high S/N ratio is made possible.Type: GrantFiled: April 14, 1988Date of Patent: February 27, 1990Assignee: Sumitomo Eaton Nova CorporationInventors: Tadamoto Tamai, Masateru Sato

Patent number: 4904909Abstract: A controller for an electric clamp closes the clamp rapidly at first, then runs at a slower speed while contacting the workpiece, and speeds up again after contacting it, to close with full clamping force. Arrival of the clamp at the position for slowing down is directly detected by means of a proximity sensor, as are arrivals at other positions. The speed of operation is relatively insensitive to the voltage of its AC electrical power source because an open-loop compensating signal controls the pulse duration of rectified DC pulses that drive the motor. The controller has dynamic braking that is applied between individual pulses of pulse trains of motor current; this results in sigfificant increase in swings of current values for a given motor speed, that reduces harmful effects of mechanical friction. Two jogging speeds are selectable.Type: GrantFiled: June 29, 1988Date of Patent: February 27, 1990Assignee: Eaton CorporationInventors: Donald L. V. Zeeland, Eugene F. Duncan, Gregory L. Nadolski

Patent number: 4902948Abstract: A guidance system for guiding a plurality of unmanned vehicles along guide wires. A plurality of data communication circuits are provided which form an extensive network. A traffic control computer composes a coded vehicle instruction for assigning tasks and allocates resources to said unmanned vehicles. The traffic control computer polls the status of each vehicle at varying time intervals and receives a response from said vehicle.The network connecting the computer and the communication circuits prevents reception of data transmissions from more than one vehicle at a time. Other messages are temporarily stored.Data transmitters generate low frequency, low power signals which have a high data transmission rate.Digital data is converted at the transmitters into cosine waveforms of selected frequencies. The cosine waveforms are transposed into sine waveforms at receivers. Low impedance or high impedance characteristics are imposed upon the guide wires.Type: GrantFiled: July 1, 1988Date of Patent: February 20, 1990Assignee: Eaton-Kenway, Inc.Inventors: Leigh E. Sherman, Gary L. Whatcott, Richard M. Dicks, David C. Madsen

Patent number: 4897758Abstract: A wound bobbin coil (A) and a fuse (B) are interconnected electrically in series. The coil and the fuse are mounted closely adjacent and molded into a tough, nylon encapsulation (C). The series connected coil and fuse are connected with electrical terminals (26, 30) to form a unitary electrical component which is readily connected with associated circuitry. In this manner, when the coil becomes damaged sufficiently to blow the fuse, both the coil and the fuse must be replaced. A repairman cannot short the fuse or merely replace the fuse and allow a damaged coil to continue functioning. In the preferred utilization of the present coil in a freezer compartment ice maker, coil failures can cause flooding, overheating, and other catastrophic damage to a refrigerator/freezer.Type: GrantFiled: August 31, 1988Date of Patent: January 30, 1990Assignee: Eaton CorporationInventors: James M. Pick, Brian T. Creed

Patent number: 4895469Abstract: A transmission shift yoke (3) (see FIG. 2) has to slide over the shift bar (1) and then be anchored accurately in the desired position by a fastener, i.e., set screw or bolt (8). The set screw must be locked to prevent its loss or more seriously its falling into machinery. A expansible snap ring (10) is arranged on a spotface (11) in a recess (12) in the bar; it is expanded by the tapered shank (14) of the fastener (8) and then snaps into a waist (19) of the fastener to prevent its being readily unscrewed more than half a turn or so. A really robust torque, however, on the head (9) by means of a spanner/wrench will forcibly expand the snap ring out of the waist (19) and over the widest part of the tapered shank (13).Type: GrantFiled: March 6, 1989Date of Patent: January 23, 1990Assignee: Eaton CorporationInventor: Jacques R. Coueron
