Abstract: In a semiconductor liquid application apparatus, a calibration tool enables the rapid and accurate adjustment of height and center of a liquid dispense nozzle. In an example embodiment, the tool comprises a circular disk in which a first beveled out area corresponding to the shape of the liquid dispense nozzle is defined on the topside of the disk. Underneath the disk, a second beveled out area corresponding to the shape of the wafer chuck is defined therein. The calibration depth is determined by the thickness of the tool's substrate less the sum of the depth of the first beveled out area and the depth of the second beveled out area. This calibration depth is determined by the configuration of the nozzle used in a liquid-dispense spinner. In using the calibration tool, the nozzle height and center becomes more repeatable from operator-to-operator and machine-to-machine.

Abstract: A CCD laser displacement gauge 9 is movable in three directions, that is, a vertical direction and two directions perpendicular to each other in a horizontal plane, and this gauge can be moved to a insulation displacement connecting center so as to detect a insulation displacement connecting height, the presence/absence of a wire, abnormal insulation displacement connection and a wire projecting amount. The insulation displacement connecting height, the wire presence/absence and the abnormal insulation displacement connection are detected by measuring a height of an upper surface of a wire sheath from a reference position at the position of the slot (at a middle position between two terminals if these terminals are juxtaposed). Whether or not the wire projecting amount is proper is determined by detecting the presence/absence of the wire at a position obtained by subtracting an absolute value of a tolerance from a normal projecting position.

Abstract: A process for accelerating a measuring wheel of a length measurement system for sawed lumber conveyed longitudinally is provided by accelerating the measuring wheel prior to engagement with the sawed lumber to avoid slippage. The rotation of a hold-down or centering roller is used for accelerating the measuring wheel through a follower roller permanently engaged with the hold-down or centering roller. The measuring wheel is pressed by an elastic pressure element both against the follower roller and into the conveyor path of the sawed lumber. As the sawed lumber is conveyed longitudinally, it comes into contact with the measuring wheel forcing it out of the conveyor path and onto the surface of the sawed lumber while simultaneously disengaging the measuring wheel from the follower roller.

Abstract: A hand-held scaler for a map or illustration uses a rotary element and an optical sensor at its tip to generate digital pulses when the tip is moved over a map surface. The pulses are counted by a microprocessor. Different pulse counts automatically scale distances on the map. The microprocessor is supplied with a number, e.g., the number miles on the map scale line; then the tip is run over the scale line (or a known distance between two points on the map). The ratio of the number and the pulse count is used to scale arbitrary distances on the map by multiplying the tip pulses by the ratio. A readout shows the scaled distance (or a mathematical function of the distance). The rotary element can be a wheel in an axle or a sphere held in a retainer, like a ball-point pen ball. The sensor has a lamp and photocell to generate pulses by a pattern of reflective and non-reflective areas on the rotary element. The housing has switches for resetting, calibrating, and initializing, and a map-illuminating light.

The linear movement between a first plane, e.g., a lens plane and a second plane, e.g., a film or print plane, at a single point, e.g., the lens optical center, is determined by measuring the linear movement of two diametrically opposed points proximate to the lens plane equidistant from the lens optical center. The two measured distances are then averaged to yield a distance measurement at the lens optical center corrected for any deflection of the lens plane.

Abstract: A self-contained, electronic, hand-held scaler for a map or other illustration uses a rotary element and an optical sensor at its tip to generate digital pulses when the tip is moved over a map surface. The pulses are counted by a microprocessor that also operates on different pulse counts to automatically scale distances on the map. The microprocessor is supplied with the number of, eg., miles on the scale line of the map and the tip is then run over the length of the scale line; the processor uses the ratio of the number and the pulse count to scale an arbitrary distance on the map. A digital readout shows the scaled distance in, eg., miles corresponding to the line run over the map. The rotary element can be a wheel in an axle or a sphere held in a retainer, like a ball-point pen ball. The sensor has a lamp and photocell to generate pulses by a pattern of reflective and non-reflective areas on the rotary element.

Abstract: An archery rangefinder for use from an elevated position comprises a power supply for an electronic digital panel meter and a power supply for two voltage divider circuits that comprise the rangefinding circuit. One voltage divider provides a voltage signal proportional to the elevation distance. This signal acts to supply the second voltage divider to attenuate the voltage further by a factor proportional to the tangent of the inclination angle. A weighted pendulum arm is attached to a potentiometric element in the second voltage divider to effect feedback relevant to the angle of inclination. All circuits and components are housed within an outer protective enclosure. Voltage across a fixed resistor in the second voltage divider is read and displayed by said digital panel meter as the range which is then used by the archer to increase accuracy of shots.

Abstract: A method of determining range from a moving vessel to an approaching object sing only two bearing measurements is provided. At a first point in time, a first bearing measurement to the approaching object is obtained using the vessel's conventional bearing sensor. The vessel and approaching object are then postulated to be on an intercept course based on the vessel's first velocity vector and first bearing measurement. At a second point in time, the vessel commences a maneuver to a known second velocity vector different from the first velocity vector. Then, at a third point in time, a second bearing measurement to the approaching object is obtained using the vessel's bearing sensor. At the same third point in time, a virtual bearing to the approaching object is provided as if the vessel and the approaching object were on the postulated intercept course.

Abstract: A sheet thickness gauging system locates sheet edges to measure sheet width and to calibrate the gauging procedure to take into account neck-in or lateral shifting of the sheet. Initially, and at regular intervals during extrusion, the controller, motor, and motor control that cooperate to control a nuclear gauge's movement and measurement on a traverse across the path of movement of the sheet, rapidly move the gauge to a first position near a first edge of the sheet. From that position to the edge the gauge steps in small steps until a substantial reduction in apparent thickness is detected, signifying the location of the edge. A limit to the regular transverse gauging movement of the gauge is set just inward of the detected first edge. The gauge is then moved rapidly across the sheet to a second position near the other edge of the sheet, where the system proceeds similarly to detect the second edge and set a second limit. Regular gauging then proceeds, across the sheet from one limit to other.
