Abstract: Apparatus for ultrasonically inspecting material radially bounding a circular bore into which the apparatus is insertable. The apparatus includes a central housing (20), three support arms (28) which are engageable with the bounding wall of the bore and are circumferentially equally spaced about the central housing (20), parallel linkage arms (22,26) joining each support arm and the central housing for maintaining a predetermined relative configuration between the support arms (28) and the bore wall, a transducer carrier (36) supported by each support arm and carrying an ultrasonic transducer (38) and means for biasing the transducers (38) radially outwardly relative to their associated carriers (36). A pneumatically actuated cylinder is disposed in the housing 20 and connected to the linkage arms (22) for movingthe support arms (28) radially outward into firm engagement with the bore wall. The transducers (38) are movable relative to the transducer carriers (36) within predetermined displacement limits and outward biasing means (44) of appropriate strength are provided to enable application of high centering forces on the support arms to coaxially align the housing with the bore's center line while independently providing relatively small, optimum engagement forces between the transducers and bore wall.

Abstract: The cutter head of a reamer carries a circular tool bit and two guide members. Each guide member has an outer-most edge at the furthest distance from the center of rotation of the tool and slanted edges inclined at progressively greater angles from the outer edge towards the front of the tool where the initial cut takes place. The first slanted edge, at an angle of less than 10 degrees and preferably between 3 and 5 degrees, intersects the outer-most edge at a point which lags the extreme point on the tool bit by about 0.4 mm in the direction of advance of the tool. The first slanted edge extends at least to the radial plane containing the extreme point of the tool bit. Thereafter, a slanted edge at an angle inclined between 15 and 25 degrees extends in the forward direction, to be followed by a third slanted edge inclined at an angle to the outer-most edge of between 30 and 75 degrees. The exact angles of inclination are determined by the diameter of the circular tool bit, which, in turn, is determined by the material to be cut.

Abstract: 57 In a magnetic memory device comprising a magnetic medium (21) having an easy axis of magnetization orthogonal to a principal surface of the medium, the medium has at least one stripe domain (20) surrounded by a domain wall which memorizes information in the form of a pair of vertical Bloch lines. Each pair is written in one end of the domain by supply of a local magnetic field to the one end when no magnetic bubble exists in the proximity of the one end. Each information is specified by absence or presence of each pair and successively transferred along the domain wall by a pulsed bias magnetic field. Readout operation is carried out at a preselected end of the stripe domain by supply of another local magnetic field to the preselected end to selectively chop the preselected end into a magnetic bubble only when each pair exists in the preselected end. Thus, presence and absence of each pair is converted into presence and absence of the bubble.

Title: A.C. motor drive apparatus
Inventor: SAKAMOTO KEIJI
IPC: H02P23/16
Filed: 1983-03-11
Abstract: An apparatus for driving an A. C. motor includes a circuit for computing the sum of polyphase A. C. signals used to drive a pulse-width modulation circuit for controlling an inverter, and for limiting the amplitude of a current command when said sum is other than zero. When an imbalance occurs in the polyphase A.C. signals, the current command amplitude is immediately limited in accordance with the state of the imbalance to prevent saturation of a current amplifier that is operable to produce the polyphase A.C. signals by amplifying the outputs of an arithmetic circuit. These outputs are difference currents obtained by computing the difference between polyphase command currents and corresponding ones of detected polyphase currents actually applied to the A.C. motor. Preventing saturation of the current amplifier assures that the polyphase currents actually applied to the A.C. motor will be held in a balanced state at all times.
