Patent CA-2105316-C (CA)
Inventor: WATANABE NIRO
IPC: B41M5/52
Filed: 1993-09-01
Granted: 2002-07-16
Abstract: An intermediate transfer medium comprises a heat-resistant base sheet and provided thereon a release layer and an image-receiving adhesive layer, on which an image pattern is formed by a sublimation transfer means in accordance with image data, said image-receiving adhesive layer, on which said image pattern has been formed, being transferred to a transfer substrate together with said release layer to produce an image-recorded article, wherein said image-receiving adhesive layer is comprised of a thermoplastic resin having a glass transition point of 50°C or above and a filler added to the thermoplastic resin and selected from the group consisting of an inorganic filler having a melting point of 200°C or above and an organic filler having a softening point or decomposition point of 200°C or above.     Because of the inorganic or organic filler contained in the image-receiving adhesive layer, there is no possibility that the image-receiving adhesive layer is transferred to the transfer ribbon side in the step of forming the image pattern even when the thermoplastic resin constituting the image-receiving adhesive layer has a low heat-melting temperature. Also, since the additive such as silicon need not be used, the layer can have an improved adhesion to the transfer substrate. In addition, since the thermoplastic resin constituting the image-receiving adhesive layer has a glass transition point of 50°C or above, the image may by no means undergo any change due to heat.

Title: Paging receiver and radio frequency channel searching method for the same
Inventor: KONDO HISASHI
IPC: H04B1/16
Filed: 1993-10-13
Granted: 2000-02-22
Abstract: A paging receiver is provided for use with a plurality of paging service systems transmitting different radio frequency channels. The paging receiver searches for every reception channel and determines object reception channels by referring to system information identifying each service system, and comprises electric field detection means for detecting the electric field strength of radio frequency channels and reception channel control means for controlling searching for radio frequency channels and determining object reception channel. The reception control means immediately switches the radio frequency channel when the received electric field strength is not greater than a prescribed value and when the system information does not exhibit coincidence, but when the system information exhibit coincidence, determines that the radio frequency channel being received is an object radio frequency channel and continues receiving of the paging information.      The time required for searching all radio frequency channels remarkably decreases thereby preventing degradation of the battery.

Abstract: A bi-leaflet prosthetic heart valve comprises an essentially circular valve ring (20), defining a circle and a valve ring plane (44), and having an internal circumference (21) which defines a flow channel (24) for the flow of blood. Further said bi-leaflet prosthetic heart valve comprises an axle (90) and two essentially half-moon-shaped valve leaflets (50, 70), both of which pivot independently of each other on said common axle (90), and being enabled - depending on the direction of blood flow -to assume an open position wherein both leaflets (50, 70) extend essentially at right angles to the valve ring plane (44), and to assume a closed po-sition wherein both leaf-lets (50, 70) extend essentially parallel to the valve ring plane (44) and virtually occlude the flow channel (24) with their combined areas. In order to offer the surgeon an additional possi-bility of influencing the flow conditions, the axle (90) extends excentri-cally, that is parallel to and at a distance from a diameter of said circle as defined by the valve ring (20). Further, one leaflet (70) comprises a larger area (75) than the area (55) of the other leaflet (50). Preferably, the leaflet (70) of larger area may occlude about 55 % to 80 % of a flow channel cross-section (25) and the leaflet (50) of smaller area may occlude about 45 % to 20 % of the flow channel cross-section (25).

Abstract: An expanded television program delivery system (200) is described which allows viewers to select televison and audio program choices from a series of menus. The primary components of the system include an operations center (202), a digital cable headend (208), and at least one set top terminal (220) having a remote control (900). The system allows for a great number of television signals to be transmitted by using digital compression techniques. A combined signal is transmitted over satellite to a cable headend (208), which may modify the combined signal for changes or additions in programming or menu content. The combined or modified signal is subsequently distributed to individual set top terminals (220) in the cable network (210). Menus are partially stored in a set top terminal (220) in each subscriber's home and may be reprogrammed by signals sent from the operations center (202) or headned (208). Numerous types of menus may be used, incorporating information included within the video/data signal received by the set top terminal (220). A remote control unit (900) with icon buttons allows a subscriber to select programs based upon a series of major menus, submenus, and during program menus. Various data gathering and analysis techniques are used to compile programs watched information that in turn is used in packaging programs, customizing menu selections, targeting advertisements, and maintaining account and billing information.

Abstract: The invention provides an apparatus for sand-blasting the inner walls of bores, tubes, pipes and the like, comprising a housing with a first tube member for feeding blasting material and a second tube member for feeding pressurized air. The sec-ond tube member is provided with a curved end portion, the ori-fice thereof being located beyond the outlet opening of the first tube member. The second tube member, together with its end portion, is rotatable around the central longitudinal axis of the first tube member. Thus, the stream of blasting material escaping from the outlet of the first tube member is deflected and accelerated under the influence of the stream of pressur-ized air escaping from the curved end portion of the second tube member. Due to the provision of such a touchless deflec-tion, the wear of the apparatus can be substantially reduced.

Abstract: The present invention provides a tool for use in wellbores. The tool is operated by the wellbore hydrostatic pressure. The tool includes one or more devices that operate when a mechanical force is applied to such devices.  The tool includes at least one atmospheric chamber. A setting member disposed in the tool is utilized to provide the mechanical force in response to the application of the hydrostatic pressure thereto. Prior to activating the tool, the setting member is locked or restrained in an inoperative position. To operate the device, the tool is placed at a suitable location in the wellbore.  The atmospheric chamber is charged with the wellbore fluid, which releases the setting member from its restrained or locked position, subjecting the setting member to the wellbore hydrostatic pressure, thereby providing the mechanical force to operate at least one of the devices. A second atmospheric chamber may be provided that remains at the atmospheric pressure, but cooperates with the first chamber as it is charged with the wellbore fluid to operate a second setting member, which operates a second device. A sensor associated with the tool detects signals transmitted to the tool from a remote location. A control circuit in the tool receives the detected signals from the sensor and in response thereto operates an electrically-operated flow control device, thereby charging the chamber with the wellbore fluid.
