Title: Synchronous motor with two permanent magnet rotor portions
Inventor: SATAKE TOSHIHIKO
IPC: H02K21/46
Filed: 1992-04-24
Granted: 2000-01-11
Abstract: 1 A synchronous motor includes a unitary rotor, a first stator (10), a second stator (14) and phase-changing switches (20). The unitary rotor has a first rotor portion formed by a first permanent magnet (2) and a second rotor portion formed by a second permanent magnet (4) and an induction type rotor (5) and these first and second rotor portions are mounted on a common rotary axle with a predetermined space provided therebetween. The first stator (10) faces the first rotor portion for producing a first rotating magnetic field. The second stator (14) faces the second rotor portion for producing a second rotating magnetic field and is disposed such that, at the starting operation, the attracting action or the repelling action produced between the first rotating magnetic field and the first permanent magnet is canceled by the repelling action or the attracting action produced between the second rotating magnetic field and the permanent magnetic field. The phase-changing switches are associated with either one of the first stator or the second stator and set a phase difference of 0 degree or 180 degrees between the first rotating magnetic field and the second rotating magnetic field. Due to the cancellation action, any starting interference which may otherwise be caused by the permanent magnets is made negligible.

Abstract: Television signals are converted from a first format to a plurality of different formats while retaining a common control data stream. A first television signal in a first format is separated into a first signal portion (12, 14) carrying television information and a second signal portion (12, 16) carrying control data. The first signal portion is reformatted into a second format (22).      The second signal portion is combined with the reformatted first signal portion to provide a second television signal (22 , 28, 32). In this manner, a plurality of television signals having different formats can be transmitted with common control data, e.g., for controlling access to television programming.

Title: Acquiring the identification of a node in a data processing input/output system
Inventor: BROWN PAUL J
IPC: H04L29/00
Filed: 1992-05-15
Granted: 1996-09-17
Abstract: A method for acquiring the node identifier of a node in a data processing input/output (I/O) system having a plurality of nodes. This procedure is part of the initialization of each node in the I/O system and may be used to establish the configuration of the I/O system such that if a connection breaks or a fault occurs between nodes, the configuration can be confirmed after the break or fault is corrected. This prevents data from being sent to the wrong device if lines were connected in a different configuration during the correction of a fault. The node identifier is a worldwide-unique identifier such that only one node is identified by a node identifier. The node identifier contains a validity code that specifies if the node identifier is valid. Also disclosed is a retry procedure for retrying the acquisition of a node identifier if the acquired node identifier is not valid, and a deferral procedure which defers the retry procedure if a link is not available.

Abstract: An absorbent article, such as a sanitary napkin, has an absorbent means and a substantially non-absorbent resilient layer adjacent to the absorbent means. The absorbent means is sufficiently stiff to resist twisting of the absorbent article during use. The resilient layer is sufficiently resilient to resist bunching during use. As a result, the absorbent article resists both twisting and bunching.      The absorbent article has zones which vary in caliper, stiffness and absorbency. A central absorbent zone is thickest in caliper, more absorbent than the other zones and is stiffer than the other zones.      An adjacent zone is less thick in caliper, less absorbent and less stiff. A peripheral zone, located near the outer side edges, is least thick in caliper, least absorbent and least stiff.

Title: Method and apparatus for image date processing
Inventor: TRENT ROBERT JOHN
IPC: H04N11/04
Filed: 1990-07-30
Granted: 1998-01-06
Abstract: A method of processing digital image data such as obtained from a television scr een for transmission along along telephone lines such thtat the transmitted data can be transformed to produce images in colour. The method includes storing a frame of incoming digital image data in a frame buffer, transferring a group of tiles from said fr ame buffer to a tile buffer, generating a clock signal, generating address and sets of control signals in a state machine, applying the clock signal to a digital transformer and applying each address and set of control signals to said tile buffer to directly transfer a block of data in the tile buffer to the digital transformer. Next the data in the block is transformed, returned to the tile buf fer and is written over the corresponding untransformed data in the tile buffer. These steps are repeated until all tiles in the tile bl ock have been transformed and returned. The transformed tiles in the tile block are then coded so as to complete their compression. The compression steps are repeated until all tiles in the frame buffer are compressed.
