Title: Time base correcting apparatus
Inventor: SUZUKI YOSHINORI
IPC: H04N5/783
Filed: 1990-11-26
Granted: 1998-07-14
Abstract: A time base correcting apparatus having a memory for storing a reproduced video signal reproduced by a rotary magnetic head from slant tracks of a magnetic tape which is transported at a desirable tape running speed relative to a tape running speed upon recording mode, a write in-line address counter for generating a write in-line address signal and a write line address counter for generating a write line address signal for the memory, a write clock signal generating circuit for generating a write in-line address increment clock signal and a write line address increment clock signal each being synchronized with a horizontal synchronizing signal separated from the reproduced video signal, and for supplying the same to the write in-line address counter and the write line address counter, a read in-line address counter for generating a read in-line address signal and a read line address counter for generating a read line address signal for the memory, and a read clock signal generating circuit for generating a read in-line address increment clock signal and a read line address increment clock signal each being synchronized with the reference horizontal synchronizing signal, and for supplying the same to the read in-line address counter and to the read line address counter, in which when the detecting circuit detects that the single cycle of one periodical signal of the periodical signals which are respectively synchronized with the reproduced horizontal synchronizing signal and the reference horizontal synchronizing signal is involved in the single cycle of the other periodical signal, the line address increment clock signal which relates to the horizontal synchronizing signal synchronized with the other periodical signal is inhibited from being supplied to the line address counter so that the reproduced video signal is removed or interpolated in the unit of lines at an equal position of a reproduced picture.          Thus, a reproduced picture having no distortion can be obtained regardless of tape running speed and tape running direction in the reproduction mode.

Title: Sanitary napkin with garment attachment panels
Inventor: VANGOMPEL PAUL THEODORE
IPC: A61F13/56
Filed: 1992-11-12
Granted: 2002-12-10
Abstract: An elongated sanitary napkin has deflectable longitudinal side edges formed by an edge or peripheral seal along the opposite sides of an absorbent. A garment attachment panel is secured to the underside of each side edge. A fixed portion of the panel is bonded flat against the side edge so that a free portion of the panel, extending from the fixed portion, is directed inward and downward.     During use, the panels are fastened together beneath an undergarment crotch portion by hook and loop type fastener. Fastener and panels are sized so that when fastened the panels exert a pull on the side edges, controlling their deflection and, for example, preventing them from folding in over the absorbent. The garment attachment panels confine the undergarment crotch portion under the absorbent so that, for example, an elasticized edge of the crotch portion is prevented from pulling up and onto the absorbent.

Filed: 1993-05-17
Granted: 1997-04-08
Abstract: A unified and automated system for providing, restoring and optimizing special services is continually aware of the state of all the equipment and facilities in the network. The unified system responds automatically to a request for a special service by 1) designating a circuit required to support the requested special service, 2) identifying network facilities and configurations for implementing the designed circuit, 3) assigning those facilities to the circuit, 4) causing the various equipment providing the facilities to be interconnected  to implement the service, S) verifying the integrity of the special service, and 6) delivering the service to the customer. In accordance with an aspect of the invention, if at any point in the process of providing a special service it is determined that there are no available direct transport facilities in the inventory of network facilities at the level required to provide the special service between the particular points in the network  that must be interconnected to provide the special service, the system will employ procedures for further identifying or developing transport facilities, in accordance with a predetermined hierarchical plan. The identified or developed transport facilities are delivered, as a unit, as a new inventory facility at the required level. In accordance with an aspect of the invention, if an indirect connection is used at any level, the new inventory unit is marked as a candidate  for optimization to be performed in the future. Thereafter the process of providing the special service can proceed as previously described.

Title: Ultrasonic transducer assembly
Inventor: OKUNUKI KAZUMICHI
IPC: G01N29/26
Filed: 1993-05-26
Granted: 1998-06-16
Abstract: An ultrasonic transducer assembly comprises a transducer unit having an array transducer composed of a plurality of transducer elements for transmitting and receiving ultrasonic waves to effect electronic scanning. and a casing for housing the transducer unit therein.  The casing has a contact surface to be brought into contact with an object to be examined, and in the casing there is disposed a swing mechanism for swinging or pivoting the transducer unit with respect to a virtual rotative axis which is determined on an electronic scanning plane produced by the array transducer and in the vicinity of the contact portion of the casing.  The swing mechanism includes a pair of guide members formed with arc-shaped guide routes concentrically arranged with the virtual rotative axis as its center, a linking mechanism for linking the transducer unit with the guide members in such a way that the transducer unit can be pivoted or swung along the arc-shaped guide routes of the guide members with respect to the virtual rotative axis; and a driving mechanism for reciprocatingly moving the transducer unit along the arc-shaped guide routes of the guide members.  In this  ultrasonic transducer assembly, a three-dimensional echo data acquiring region can be produced based on the shift of the electronic scanning plane with the virtual rotative axis as its center by the swinging mechanism.  The virtual rotative axis is located in the vicinity of the contact surface of the casing.  Therefore, when the contact surface of the transducer assembly is brought into contact with the body surface between the ribs of a patient to be examined, it is possible to acquire three-dimensional echo data through the space between the ribs, without being subject to the influence of the presence of the ribs.
