  • Patent number: 10689187
    Abstract: A rotor securing jig secures a rotor extending along an axis inside a container. The rotor securing jig includes a first member that is able to be secured to a first end portion of the rotor, which is an end portion of the rotor on a first side in an axial direction, a second member that is provided relatively movable in the axial direction with respect to the first member, and a third member that is secured to the container, has a first abutting surface facing a second side in the axial direction, which is an opposite side to the first side, and abutting the first member, and has a second abutting surface facing the first side and abutting the second member.

  • Publication number: 20140150272
    Abstract: An electronic caliper generates power for measurement operations. The caliper comprises a scale member, a slider, a signal processing portion configured to measure a displacement between the scale member and slider, a power generating arrangement attached to the slider comprising a gear assembly configured to rotate in response to a force provided through a power generating handle to the gear assembly by a user moving the power generating handle relative to the gear assembly, and a power generator coupled to the gear assembly and configured to rotate in response to force provided by the rotating gear assembly and provide power to the signal processing portion. The power generating arrangement generates power as the user moves the power generating handle, and the power generating arrangement contributes a motion resistance force component of at most 20N as the user moves the power generating handle with a maximum manual acceleration.

  • Patent number: 6823603
    Abstract: The present invention is directed to an apparatus and method for marking an angles relative to a baseline, the apparatus comprising two elongate arms, one arm having a length greater than that of the other, the arms being pivotally joined at one end by a connecting means having an aperture and anchoring means attached to the other ends for anchoring the arms to a first marker at one end of the baseline and a second marker marking the other end of the baseline to a specified length. The baseline length determines the size of the angles given the constant lengths of the first and second arms. The method may be employed by a single unskilled user to mark angles of any size greater than 0 and less than 180 degrees. The apparatus may be sized and proportioned for use on projects of widely varying scales.

  • Patent number: 6647637
    Abstract: A downhole caliper instrument utilizing a linear or arcuate magneto resistive sensor to determine the position of one or more caliper arms which extend from a carrier tool to touch the surface of a borehole wall. A processor and firmware are included to calculate and plot the borehole radius. A plurality of magneto resistive sensors are provided to calculate the sine, cosine and tangent for accurate motion of each independent arm. The magneto resistive sensors sense the position a precise magnetic ruler linked to the caliper arm. The position of the caliper arm determines the radius of the borehole. Calculation of Radius/Diameter is preferably performed in the computer on surface. The downhole controller's firmware controls the multiplexer switching, A/D conversion and other functions.
