Patent CA-2062041-A1 (CA)
Inventor: WADA KATSUO
IPC: G11B7/12
Filed: 1992-02-28
Abstract: An information processing, i.e. reproducing and recording, apparatus which has a rotative driving means for rotating a disk-shaped recording medium, a floating-type head for reproducing information recorded in the recording medium while floating above the disk-shaped recording medium that is being rotated by the rotative driving means, and a suspension, made of an elastic member, for supporting the floating-type head. The floating-type head has a slider which is floated by an air flow that is directed near the surface of the rotating disk-shaped recording medium. The slider has a bevelled portion at one side that faces the outer edge of the disk-shaped recording medium, such that any contact between the slider and the ridge that exists along the outer edge area of the disk-shaped recording medium is virtually eliminated. Since the slider virtually avoids contact with the ridge that exists along the outer edge area of the disk-shaped recording medium, the storage capacity of the disk-shaped recording medium can be more effectively used.

Title: Multilayer head box for a paper machine or similar
Inventor: BUBIK ALFRED
IPC: D21F9/00
Filed: 1993-07-22
Abstract: Abstract of Disclosure:     The proposed multilayer head box for a paper machine or similar is constructed so that it can produce a wide jet consisting of at least three individual jets (5, 5', 5"). The individual jets are fed through separate channels (3, 3', 3") and emitted out of the head box and subsequently combine to form a single wide jet. The individual channels are so constructed that further outer lying jets can be diverted sufficiently after having been emitted out of their respective channel, so that they meet the respective further inner lying partial stream at a very slight angle. The problem of separation when the partial streams are diverted as well as that of undesired lateral mixing when the partial streams are combined are thereby prevented.            (Fig. 4)

Title: Methods and apparatus for performing ultrasonic assisted surgical procedures
Inventor: VAITEKUNAS JEFFREY J
IPC: A61B17/068
Filed: 1993-11-15
Abstract: Ultrasonic sensing systems are incorporated into surgical instruments to monitor operational fields defined by distal ends of the instruments. The instruments include proximal ends for their activation typically including one or a pair of handles which a surgeon grasps and operates, for example by squeezing the handles together or by pivotally moving a trigger portion of the handle relative to a fixed portion of the handle. Circuitry for performing ultrasonic sensing preferably is enclosed in housings defined within the handles of the proximal ends of the instruments. Wiring, preferably running through the instruments, connects the circuitry to transducers formed in or mounted on the distal ends of the surgical instruments. The transducers direct ultrasonic energy to the operational fields defined by the distal ends of the instruments and receive ultrasonic energy reflected from the operational fields. The direction for transmission and receipt of ultrasonic energy is determined by acoustic lenses, angularly oriented transducer mounts or a combination of the two.    Signals representative of the tissue or contents of the operational fields of surgical instruments drive audible signal generators or preferably tactile transducers to inform the surgeon of the contents. Tactile transducers are mounted for access by the surgeon, preferably on the handles of the surgical instruments:
