Title: AC motor drive apparatus
Inventor: TANAKA SHIGERU C O PATENT DIVI
IPC: H02P27/04
Filed: 1987-07-06
Abstract: An AC motor drive apparatus of this invention is constituted by an AC power source (SUP), a first circulating current type cycloconverter (CC-1) having an output terminal coupled to the AC power source, a phase-advanced capacitor (CAP) coupled to an input terminal of the first cycloconverter, a second circulating current type cycloconverter (CC-2) having an input terminal coupled to the phase-advanced capacitor, and an AC motor (M) coupled to an output terminal of the second cycloconverter. The first cycloconverter (CC-1) controls a current (IR, IS, IT) supplied from the AC power source (SUP) to be a sine wave (ea, eb, ec) in the same phase as that of the power source voltage, so that a voltage crest value (Vcap) of the phase-advanced capacitor (CAP) becomes substantially constant. The second cycloconverter (CC-2) supplies a sine wave current (Iu, Iv, Iw) of a variable frequency (0 to several hundred Hz) to the AC motor.

Abstract: A filtration means (50) is provided in a data recording disk file for filtering air flowing from the region (44) of the spindle bearings (24,26) into the head/disk area (16) of the disk file. The filtration means is mounted to the disk file frame (10) adjacent the rotary shaft of the spindle (20) and together with the shaft defines a narrow annular gap for the flow of a very small portion of the total air flow from the region surrounding the spindle bearings. The filtration means includes first (52) and second (56) ring members which have axially-­directed openings (54,58) and which together support filter material (60) located between the ring members. Almost all of the air flowing from the spindle bearings passes through the axially-directed openings of the ring members and the filter material and is thus filtered before entering the head/disk area. The filtration means also serves as a make-up filter for those generally sealed disk files in which the rotating disks serve as a pumping means for recirculating air within the head/disk area and in which the region surrounding the drive motor is open to the atmosphere.

Abstract: A display source emits light. A first hologram (22) receives the light from the display source (21) and diffracts the received light. The light from the display source (21) is applied to the first hologram (22) at an incident angle A1 and moves from the first hologram at an outgoing angle B1. A second hologram (23) receives the light from the first hologram and diffractively reflects the received light. The light diffractively reflected by the second hologram (23) forms an image of the display source in viewer's field of view. The light from the first hologram is applied to the second hologram at an incident angle A2 and moves from the second hologram at an outgoing angle B2. The first and second holograms are nonparallel to remove a ghost image of the display source which would result from at least one of surface reflections at the first and second holograms. The first hologram has an angle ϑ relative to the second hologram. The angles A1, B1, A2, B2, and ϑ are in a fixed relationship to remove chromatic aberration which would result from the nonparallel arrangement of the first and second holograms.

Abstract: The yarn (1) is wound onto a cross-wound package (4) by means of a grooved drum (3), and a first sensor (6) is provided for determining the circumferential speed of a member rotating synchronously at the speed of the traversing yarn. A second sensor (7) determines the position of the yarn (1) on the package (4) in relation to the longitudinal axis thereof, and a correction factor is derived from this determination in order to determine the instantaneous yarn speed from the mean yarn speed obtained from the circumferential speed of the rotating member. 
<??>This improves the determination of the yarn speed in textile machines to such an extent that on-line spectrograms can be measured on the latter. Moreover, the accuracy with which the length of the yarn defects is measured is also increased by an order of magnitude.

Abstract: An electrically-erasable, programmable ROM cell, or an EEPROM cell ( 10 ), is constructed using an enhancement transistor merged with a floating-gate transistor, where the floating-gate transistor has a small tunnel window ( 19 ), in a contact-free cell layout, enhancing the ease of manufacture and reducing cell size. The bitlines ( 13 ) and source/drain regions ( 15,16 ) are buried beneath relatively thick silicon oxide ( 14 ), which allows a favorable ratio of control gate ( 12 ) to floating gate ( 17 ) capacitance. Programming and erasure are provided by the tunnel window area ( 19 ), which is located near or above the channel side of the source ( 15 ). The window ( 19 ) has a thinner dielectric than the remainder of the floating gate ( 17 ), to allow Fowler-Nordheim tunneling. By using dedicated drain or ground lines ( 13 ), rather than a virtual-ground layout, and by using thick oxide ( 22 ) for isolation between bitlines ( 13 ), the floating gates ( 17 ) can extend onto adjacent bitlines ( 13 ) and isolation areas ( 22 ), resulting in a favorable coupling ratio. Isolation between cells in the wordline direction is by a self-­aligned implanted region ( 21 ), in this embodiment.
