Abstract: A device for positioning an elongate gravity-actuated measuring instrument, such as a goniometer, adjacent two three-dimensional objects to measure an angle between the two objects includes first and second members. The first member is joined to, and extends away from, such instrument, and positionable against a surface of one of such objects. The second member is joined to, and extends away from, such instrument, is spaced from the first member a preselected distance, and is positionable against a surface of the other of such objects. Preferably, the first member is formed as a frame that is coupled to such instrument, and the second member is formed as an elongate positioning probe that is coupled to the frame. The device may also be formed with rotational-attachment structure, both to allow attachment of the second end of the probe to the frame and, when attached, to allow rotation of the probe about an axis defined by the long axis of the probe.

Abstract: A metrology device determines the position of a machine component relative to a datum along three linear and three rotational axes. The metrology device has a pair of support structures connected by six legs that are each disposed at an angle with respect to the next adjacent leg. One of the support structures can be connected to the datum and the other can be connected to the machine component. A sensor cooperates with each leg to sense the actuation of that leg as the support structures move relative to one another. The combination of signals provided by the legs can be used to track movement of the machine component relative to the datum.

Abstract: A thermocouple for use in an apparatus for manufacturing a semiconductor device having two metal wires, each composed of a different material, being connected at one end. A first insulator extends a first length from the connected end of the metal wires and electrically insulates a portion of one of the metal wires. A second insulator, having a brittleness factor less than that of the first insulator, extends a second length from the first insulator along the same metal wire. The lifetime of the thermocouple can be lengthened and productivity of the semiconductor device can be enhanced.

Abstract: A golf club fitting system and method relate to the use of a golf club having its head rockably mounted on a base to enable the user to position the head adjustably. A club head orientation sensing device determines the loft angle of the club face when disposed in the desired adjusted position. A microcomputer responds to the sensor indicating the measured loft angle and other parameters such as the right handed or left handed user information and the intended playing surface condition information. A device responds to the microcomputer to display the determined loft angle desired for the given user.

Abstract: A rear sight is provided for attachment to a bow which has been fitted with a forward bow sight of the type having a pin, the distal end of which can be aligned with a target to aim an arrow. The rear bow sight includes an arm having a forward and rearward end, the forward end being mounted on the bow and the rearward end has a second pin thereon. The distal end of the first pin, and the distal end of the second pin, are sighting points for aiming an arrow to be launched at a target by the bow.

Abstract: A tracing tool for marking an outline of an irregular surface onto a sheet of material so that the sheet of material can be cut along such outline to fit snugly against the irregular surface, such tool including a case having a cavity in communication with an opening in the case, such case enclosing a piston having a shaft linearly extending therefrom through the case opening with a spring biasing the piston toward the case opening, and a marking device passing through a marking hole in the shaft which marking hole is perpendicular to the plane of the sheet of material. The shaft at its end includes a horizontally disposed guide roller for facilitating sideways rolling of the shaft along the irregular surface while the shaft moves back and forth perpendicularly to the irregular surface which movement moves the piston in the cavity as the marking device marks the outline of the irregular surface on the sheet of material.

Abstract: A thermometer is provided with a ROM, in which a program for controlling a CPU and plural predetermined emissivity data are memorized, and is further provided with a RAM having plural registers, in which plural emissivity data are entered and memorized. One of these memorized emissivity data is selected and used for measuring a temperature of an object. The selected emissivity data and an output of a temperature sensor are amplified by an amplifier, and are supplied to an A/D convertor to obtain digital data. The CPU processes the digital data to obtain temperature data, and displays the obtained temperature data. With this structure of the thermometer, emissivity data can be set with a simple operation.

Abstract: A method for adjusting toe on a steerable vehicle wheel including the steps of obtaining and storing a preadjustment toe value for a first wheel, moving the first wheel to a adjust position, obtaining and storing an initial toe value for both steerable wheels when the first wheel reaches its adjust position, adjusting toe angle on the first wheel, using the preadjusted toe value and initial toe value for the pair of wheels to obtain an adjusted toe value for the first wheel, and continuing the adjustment of toe angle on the first wheel until the adjusted toe value is substantially within a first wheel toe specification, whereby toe is adjusted without locking the steering wheel.
