Abstract: A method of controlling a three-phase, three-level inverter comprises the steps of: judging whether the current of the output terminal of an inverter of the phase such that the electrical potential of the output terminal equals to the neutral-point terminal of the capacitor among three-output terminals of the inverter is in a positive direction in which current flows into a load connected to this output terminal or in a negative direction in which current flows from the load when another on/off mode having the same instantaneous space voltage vector as the instantaneous space voltage vector in a tentatively selected on/off mode exists; actually selecting the tentatively selected on/off mode if the result of the judgment is positive and actually selecting another on/off mode instead of the tentatively selected on/off mode when the result of the judgment is negative in the case where the electrical potential of the neutral-point terminal of the capacitor is above a preset upper-limit value; and actually selecting the tentatively selected on/off mode if the result of the judgment is negative and actually selecting another on/off mode instead of the tentatively selected on/off mode when the result of the judgment is positive in the case where the electrical potential of the neutral-point terminal of the capacitor is below a preset lower-limit value.

Abstract: An X-ray tube for a CT apparatus comprises a ring-shaped vacuum tube (12) containing a fixed cathode (13) having a thermion emitting surface, a ring-shaped fixed anode, (15) and a ring-shaped rotatable cathode (14) interposed between the fixed cathode and fixed anode. The rotatable cathode defines a thermion receiving surface (49) opposed to the thermion emitting surface, and a thermion emitting portion (41) opposed to the fixed anode. Thermions are emitted from the thermion emitting portion toward the fixed anode while the rotatable cathode is suspended to non-contact state and rotated at high speed. With the thermions being accelerated and colliding on the fixed anode, an X-ray is generated toward the center of the vacuum tube. The X-ray generating position moves at high speed along a circumferential surface of the fixed anode with rotation of the rotatable cathode.

Abstract: An ultrasonic tube inspection system (10) capable of rapid changeover for inspecting tubes (T) of different diameter sizes includes a serial arrangement (14) of multiple separate inspection stations (14A, 14B). One inspection station (14A) is used to inspect for tube dimensions irrespective of the tube diameter size. The other inspection stations (14B) are used to inspect for flaws and are employed for different ones of the tube diameter sizes to be inspected. A set of ultrasonic transducer assemblies (58, 60) is supported at each inspection station. The transducer assemblies (58, 60) at the flaw inspection stations (14B) are in proper orientations corresponding to the diameter sizes of the particular tubes (T) to be inspected at the respective inspection stations without the need for readjustment. The inspection stations contain quantities of liquid for coupling ultrasonic energy between the ultrasonic transducer assemblies (58, 60) and the tube (T) passing through the inspection stations (14A, 14B). Liquid level control stations (18, 20) are disposed at opposite ends of the serial arrangement (14) of inspection stations (14A, 14B) and are connected in flow communication with the inspection stations (14A, 14B) for controlling liquid level in the inspection stations. Tube drives (22) are disposed adjacent the liquid level control stations (18, 20) and are operable to drive the tubes (T) through the control and inspection stations such that the tubes (T) are aligned along a common centerline (C) irrespective of which tube diameter size is being inspected.

Abstract: A method and apparatus is described for measuring the resistivity of a formation adjacent a borehole. It relies on a modified induction approach and preferably is incorporated into a metal drill collar for MWD measurements. Directional nulls are created in a primary changing magnetic field formed in a formation by a transmitting antenna which is in a groove on the surface of the drilling collar. Detecting antennas are placed at the directional nulls to enable the primary magnetic field to be decoupled from the same and allow it to be distinguished from the secondary field caused by the current induced in the formation by such primary field. The drill collar also carries a plurality of current detectors which detect the value of current which is induced in the formation to provide a resistivity profile immediately adjacent the borehole. The preferred embodiment described uses a hybrid modified induction and electrical approach.

The personal computer has a local processor bus; and a microprocessor, volatile memory, a memory controller and a bus controller coupled to the local processor bus; volatile memory coupled to the local processor bus. The bus controller provides communications between the local processor bus and a slower speed input/output bus. A keyboard controller has an output port register coupled to the bus controller and memory controller for providing communications between a manually operated keyboard for data entry and the input/output bus. A controlling data word is stored in the register for defining the characteristics of signals emitted from the port, and a mask value for the controlling data word is stored in the computer system for defining any portions of the controlling data word which may be varied in accommodating varied operation as may be required for the operation of varied application program software. The keyboard controller and computer system cooperate for reading the controlling data word and mask value and any modifying data word directed to the output port register by any application program software and for writing to the output port register a new controlling data word modified only in those portions defined as variable by the mask value.

Abstract: A servomotor-driven U axis tool member rotation device for a boring and facing head (48) is affixed to a machine by a bracket (29), and has a torque coupling (46, 47) slidable on the servomotor shaft. A cover (39) is mounted to a pivot shaft (41) on the bracket, and is rotated by the servomotor to selectively cover and uncover the torque coupling. The cover pivot shaft has a driven gear (53), and the torque coupling has a driving gear (54). When a U-axis head is disengaged from the torque coupling and machine spindle, the gears are held in mesh by a biasing spring (75) applied to the torque coupling, and the cover may be rotated. When a U-axis head engages the torque coupling, the biasing spring is overcome and the gears are forced out of mesh; at this time, the servomotor may rotate the input tool member of the U-axis head to position its tool, while the cover remains stationary in the open position.

Abstract: A system and method are provided for improving quality of sound generated by computerized systems having limited memory. A wavetable synthesizer is implemented wherein data utilized to synthetically generate acoustic waveforms is stored. A plurality of datasets is also generated and stored, each comprised of a digitized acoustic waveform. In response to a MIDI datastream, the system determines if an appropriate stored acoustic sample corresponding thereto resides in the system's memory. If so, the system will generate the desired sound utilizing the stored acoustic sample data. If not, the system automatically determines in real time the appropriate wavetable dataset which will generate a sound most closely approximating the acoustic sound. The system thus dynamically reconfigures in real time between wavetable and acoustic sample synthesis, being configured for the former when appropriate acoustic samples are not present.
