Title: Radio paging receiver capable of muting battery saving function
Inventor: MORI TOSHIHIRO
IPC: H04W88/02
Filed: 1982-07-13
Granted: 1985-03-12
Abstract: ABSTRACT   A radio paging receiver includes: a receiver section for receiving and demodulating a carrier modulated with a preamble signal, a specified signal for test, and a call signal including an address signal.  The receiver also has a memory for storing in advance an identification number assigned to the radio paging receiver and circuitry for detecting the preamble signal from the output of the receiver section to provide a preamble detection signal.  An identity detecting section compares the address signal supplied from the receiver sec-tion and an output read out of the memory and, upon detection of their coin-cidence, supplying an identity signal.  An alert signal is generated in response to the identity signal.  A battery saving circuit is provided for supplying power from a battery to the receiver section either intermittently in a pre-scribed cycle so that the receiver section can receive at least the preamble signal or for a prescribed period of time so that the receiver section can receive the address signal in response to the preamble detection signal.  A specified signal detecting circuit is provided for detecting the presence of the specified signal from the output of the receiver section and supplying a signal to suspend battery saving; and a battery saving suspending circuit for muting or suspending the battery saving circuit in response to the signal to suspend battery saving and continuously supplying said power to the receiver section, thereby placing the receiver in condition for test operation.  The invention permits a paging receiver having a battery saving function to be tested without having to resort to external manipulation of the paging receiver for temporarily suspending the battery saving operation.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to a process for producing low energy dispersion vinyl copolymers which, in a plastisol, can be fused at lower tempera-tures or in a shorter period of time than presently available dispersion vinyl copolymers.  It has been found that if, instead of adding all the comonomer batchwise prior to the start of the reaction, the comonomer, such as methyl acrylate, for example, is metered into the reactor continuously, or intermittent-ly, during all or part of the polymerization reaction period, a dispersion vinyl copolymer is produced that has a lower plastisol viscosity for a given comonomer content.  Plastisols made from the vinyl copolymers of the present invention have good flow properties and the fused films made therefrom have high gloss, high clar-ity and good mechanical strength, even when fused at low temperatures.

Abstract: CARDIAC PACING LEAD WITH BIODEGRADABLE FIXATION MEANS                            ABSTRACT         Disclosed is a cardiac pacing lead comprising an electrical stimulating member (electrode) with a plurality of biodegradable fins adjacent to its tip and with or without a porous metal coating.  After surgical introduction, temporary fixation of the device to the surface of the cardiac wall is supplied by the fins.  The device achieves permanent fixation by ingrowth of viable tissue into the interstices of the porous electrode and/or by tissue ensheathment of the distal portion of the lead.  The process of permanent fixation occurs over a period of weeks during which time the fins are gradually absorbed into the blood and/or adjacent tissue.  The lead can also be used to stimulate tissue other than cardiac tissue, such as nervous system tissue.

Abstract: THROTTLE POSITIONING DEVICE                 Abstract of the Disclosure A throttle positioning device comprising a housing and a diaphragm in the housing dividing the housing into first and second chambers.  The housing has an opening extending to the first chamber for connection to vacuum.  A solenoid is associated with the housing and has a plunger acted upon by energization of the solenoid.  The plunger is yieldingly urged by a light spring against a solenoid stop connected to the diaphragm such that the stop is movable with the diaphragm.          A stem is adapted to be moved by the plunger and extends through the movable stop to the exterior of said housing to define a movable throttle stop.  The throttle lever, attached to the throttle shaft of the carburetor yieldingly urges the throttle stop to a retracted position against the lighter spring force of the solenoid plunger.  The diaphragm is yieldingly urged to move the movable solenoid stop toward the solenoid.  When the solenoid is energized and vacuum is not being supplied to the first chamber, the stem is in a first position, and when said solenoid is energized and vacuum is supplied to the first chamber, the stem is in a second position.  When the engine is stopped and the solenoid de-energized, the throttle element urges the stop to a third position against the action of the lighter spring to provide an anti-dieseling function.  In another form, the throttle positioning device includes a wall in the housing cooperating with the first diaphragm to form a second chamber, i.     and a second diaphragm cooperates with the wall to define third and fourth chambers.  The housing has an opening for connec-tion to vacuum to the third chamber.  The first and second diaphragms are movable independently of one another, such that when the solenoid is energized and vacuum is applied to the second opening, the second diaphragm moves the first diaphragm to move the magnetic stop permitting the stem to be moved by the solenoid plunger to a fourth position. ii.

Abstract: AN IMPROVED METHOD OF ENCAPSULATING BIOLOGICALLY ACTIVE MATERIALS IN MULTILLAMELLAR LIPID VESICLES (MLV) ABSTRACT       This invention provides an improved procedure for producing large multilamellar lipid vesicles (MLV), which may be used to encapsulate a biologically active material, particularly lipophilic substances. According to this invention, a lipid film is formed on inert, solid contact masses within a vessel, by evaporating an organic solvent therefrom. Subsequent agitation in the presence of an aqueous liquid, followed by a period in which the vessel remains undisturbed yields the multilamellar vesicles. The procedure permits the encapsulation of both hydrophilic and lipophilic materials.

Abstract: ABSTRACT      A geodesic dome structure is described, i.e., a structure having a mathematically-derived surface.  This new dome structure is formed of a single, one-piece layer of synthetic material and provides a one-piece, seamless screen to permit the viewing of a scene in a vehicle simulator in order to achieve a maximum of real-ism matching substantially real world conditions.  One form of the structure for this geodesic dome is described with the single, one-piece layer of synthetic material bonded to a generally dome-shaped geodetic structure in order to provide sufficient strength for a free-standing structure.  However, another form of the geodesic dome is described with the synthetic material formed of suf-ficient thickness to be strong enough to provide a free standing structure, and the synthetic material may even be reinforced if desired.  The method described of achieving this geodesic dome includes erecting a generally dome-shaped geodetic structure and applying a coating of a predetermined thickness of synthetic material to the inner surface of such a structure.  Thereafter, this synthetic material is smoothed to provide the seamless screen for viewing a scene from a vehicle simulator. The method described also includes a tool stand erected in order to locate positively a pivot point from which a tool boom is movable in order to achieve the accuracy desired for the inner, smooth, one-piece, seamless screen surface.

Abstract: ABSTRACT: Device for producing coherent radiation.     By means of electrons (7) of high energy produced by a semiconductor cathode (3), population inversion is obtained in an active layer (13) of a laser structure (11). In this manner, laser action is obtained, which offers advantages especially with II-VI materials which emit radiation of a wavelength shorter than the usual III-V materials, and which do not permit the desired population inversion to be obtained in the same manner as in III-V materials, by means of current injection across a pn junction. The semiconductor cathode (3) and the laser structure (2,11) can be both arranged in mutual separation in a vacuum tube (5) or be realized in one semiconductor body. The short-wave laser is especially advantageous for CD,DOR and VLP applications.
