Title: Portable radio apparatus having battery saved channel scanning function
Inventor: MARU TSUGUO
IPC: H04M1/73
Filed: 1988-02-22
Granted: 1993-07-06
Abstract: Abstract of the Disclosure A portable radio apparatus comprises a receiving section capable of being tuned to any of a plurality of channels, a switch circuit for controlling supply of power from ? battery to the receiving section and a detector circuit for detecting strength of electric fields which are developed on said channels.   A control section is connected to said receiving section and the switch circuit and constructed such that, in response to an output of said detector circuit,  the control section executes channel scanning for tuning the receiving section sequentially to the channels while, at this instant, controlling said switch circuit to feed power continuously to the receiving section and, when no data has appeared on said channels within a first predetermined period of time during the channel scanning, executes saving scanning for repeating a cycle in which said channels are sequentially scanned by one round and,  then,  the scanning is interrupted for a second predetermined period of time while, at this instant, controlling the switch circuit to feed power to the receiving section in synchronism with the saving scanning.

Title: Vehicle navigation system
Inventor: ZEEVI ELIAHU I
IPC: G01S11/04
Filed: 1988-03-17
Granted: 1992-02-25
Abstract: VEHICLE NAVIGATION SYSTEM               ABSTRACT OF THE DISCLOSURE A vehicle navigation system is provided wherein a preselected route is established in terms of a sequence data and processing means computes sequence action data based on lineal distances between landmarks, such as junctions, and movement detective means, such as a turn detection, for detecting movement only around an approached landmark in order to synchronize position with the landmark.  In accordance with the invention, it is unnecessary to store all geographic data about a region to be traversed during a journey and further computation can be extremely efficient without reliance at any time or detection of direction with respect to magnetic north or other fixed, remote reference.  All needed information is incorporated into data related only to distance travelled by the vehicle between landmarks and movement around (e.g., turns) an approached landmark.  The system works on the assumption that the vehicle moves in one dimension between predetermined landmarks so that route information can be reduced to a sequence of indicators.          The movements around landmarks, or more specifically junction or turns where deviations are expected from a straight line constant velocity path are used to synchronize vehicle location relative to the landmark.      The accuracy of map distance between landmarks is assumed within an acceptable error so that synchronization can be obtained within a window distance during which the system seeks synchronization.

Abstract: ABSTRACT      The invention relates to a variable capacity compressor for use in automobile air conditions, for example.  The variable compressor allows the cooling capacity to be continuously changed with fine control of the cooling capacity as required.  The variable compressor comprises an enclosure having cylindrical internal space.  A cylindrical-shaped rotor is rotatably held in the enclosure and driven by an external force and has vanes.  Plural return ports are formed on a wall of volume-decrease-step space in the internal space wherein the volume of sectioned space by movements of the rotor and the vanes is changed cyclically.  An exit is formed on the wall of volume-increase-step space in the internal space wherein the volume of sectioned spaced by movements of the rotor and the vanes is changed cyclically.  A C-shaped guide passage is formed in the wall for connecting the plural return ports and the exit.  An arc-shaped slider is provided slidably in the guide passage for opening and closing the plural return ports with a pressure control compartment retained in the guide passages.  A bias spring is provided for urging the slider in a direction to close the return ports.  Control pressure supply means supplies control pressure to the pressure control compartment and comprises a pressure detecting part which compares suction pressure with atmospheric pressure, thereby to generate a displacement thereof, a valve urged to close by a spring, a rod driven by the pressure detecting part for opening the valve, and an electromagnetic coil for applying electromagnetic force to the valve, thereby to urge the valve in a direction to open.

Title: Implantation of prosthetic devices
Inventor: GIBSON DAVID
IPC: A61F2/16
Filed: 1988-11-09
Granted: 1994-04-05
Abstract: IMPLANTATION OF PROSTHETIC DEVICES ABSTRACT OF THE DISCLOSURE Prosthetic devices are prepared for subepithelial implantation by coating their surfaces with a coating comprising crosslinked or uncrosslinked fibronectin. If the surface of the device comprises a material which does not normally bind fibronectin, it is pretreated, for example, by coating with poly(L-lysine). The coated prosthetic device is implanted by removing a portion of the epithelium, affixing the coated device to the subepithelial tissue optionally replacing all or part of the removed epithelium, and allowing new epithelial tissue to grow over and affix itself to the surface of the prosthetic device. The method of the invention can be used to implant contact lenses permanently beneath the epithelium of the cornea.
