Title: High sensitivity fm signal demodulation system
Inventor: OHTA TOMOZO
IPC: H04N11/24
Filed: 1982-08-04
Granted: 1985-07-02
Abstract: ABSTRACT The present invention relates to an improved demodulation system which improves the noise characteristics for the demodulation of a wideband television FM signal. A variable bandpass filter for improving the C/N ratio is provided at the output of a reference bandpass filter. This variable bandpass filter, of which the center frequency and bandwidth are controllable, is inserted in an FM signal path along with the bandpass filter. The bandwidth of the variable bandpass filter is controlled so that it is wide when the input carrier level is high, and is narrow when the input carrier level is low. The center frequency of the variable bandwidth filter is controlled so that it follows the instantaneous frequency change of the color sub-carrier component (3.58 MHz) of the FM signal, the latter being derived by a narrow-band bandpass filter coupled with the output of a discriminator also residing within the circuit and as a result, control of the center frequency of the variable bandpass filter is achieved. This system is advantaseous over prior art systems in that it will follow the instantaneous frequency change of FM input signal to the system, and improve the impulse noise characteristics which reduces the demodulated waveform deformation.

Abstract: ABSTRACT OF THE DISCLOSURE      A synthetic polymeric ice nucleation inhibitor is  employed  for  protecting  light  frost-sensitive plants  against  frost  injury  by  inhibiting  the ice nucleating   activity   of   the ice-nucleating bacteria normally present on the plants, and thereby reducing  the  temperature  at  which  frost  injury occurs.  The inhibitor is applied to the plants in the form of a solution of a synthetic polymer having covalently bound to its main backbone chain both pendant hydrophobic groups and pendant hydrophilic groups.   The  ratio of  and  average  intermolecular spacing  between  the  hydrophobic  groups  and  the hydrophilic groups in the polymer, and the molecular weight  of  the  polymer,  are  selected  so  that  in combination they provide the polymer with a limited room temperature water solubility within the range of  from about  1  µg/ml  to  about  100 mg/ml.   The inhibitor  is  also  applicable  for  reducing  the temperature at which ice  formation occurs in any other  medium  containing  active  ice  nucleation initiators, such as, for example, the atmosphere and concrete    as  well   as   having  utility   as   a species-specific bactericide, such as, for example, against Pseudomonas syringae.

Abstract: ABSTRACT      An apparatus for detecting ruptures in a drill pipe above and below the drill collar comprising a nose cone, a lower body threadably engaged to the nose cone.  The lower body has a structure defined by a plurality of circulation by-pass apertures and shear pin apertures.  A cylinder actuator having actuator apertures is installed within the lower body juxtaposed to the shear pin aper-tures.  Shear pins slideably lodge through the shear pin apertures of the lower body into the actuator apertures of the cylinder actua-tor.  A steel ball seats on top of the cylinder actuator.  An upper body threadably engages the lower body and a retrieval cap thread-ably engages the upper body.  The apparatus seats into a seating sub in operation of the invention.  The method of detecting and cor-recting ruptures in a drill pipe above and below the drill collar to prevent loss of drilling mud comprises running a seating sub in the drill string at the top of the drill collar and subsequently dropping a washout locator tool into the drill pipe until the tool seats in the seating sub.  The drill string is pressurized above the seated tool to a predetermined pressure.  The predetermined pressure is monitored to ascertain whether or not the predetermined pressure holds without bleeding off, indicating that there is no noticeable leak in the drill string between the tool and the sur-face, or doesn't hold and bleeds off indicating that there is a leak.  If the pressure holds without bleeding off, shearing pins are sheared in the tool to establish circulation and the drill string is pulled dry and the bottom hole assembly below the drill collar is checked.  When the pressure does not hold, the drill string is pulled in order to detect and correct any ruptures which cause the decrease in the predetermined pressure.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for optically coupling a plurality of optical fibers in predetermined combinations.  Each optical fiber fits into and is supported by an expanded-beam type optical component that is optically structured to collimate, or nearly collimate, the output from an optical fiber when the fiber is located at, or nearly at, the focus of the optical component.  The optical components fit into a hous-ing that is adapted to receive and support them such that at least one of the components is nominally aimed in a first direction and the other optical components are nominally aimed in a direction different from the first direction.          The housing includes optical means, including a holographic layer or layers, of predetermined size positioned within the housing to intercept the output from the optical component aimed in the first general direction and precisely direct it into predetermined ones of the other optical components aimed generally differently thereto and to precisely direct the output from any of the similarly aimed optical compo-nents into the end of the fiber located in the optical com-ponent aimed in the first direction.  The apparatus permits the tolerances related to the angular tilt of the lens sur-faces of such optical components to be greatly relaxed com-pared to what they would otherwise need to be to have the same throughput from fiber to fiber when used without the apparatus of the invention.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention provides a flow regulator for gaseous substances, particularly a flow regulator for air in air-conditioning and ventilation installations, for maintaining the volumetric flow of the gaseous substance at desired magni-tude with sufficient accuracy when the differential pressure acting across the flow regulator varies within given limits.          The flow regulator comprises an envelope and a regulating mem-ber rotatably disposed in the flow passage defined by the en-velope.  The torque produced by the flow of gaseous substance on the regulating member and a countertorque dependent on the position of the regulating member cause the regulating member rotating  in the flow passage to assume a position of equilibrium such that the requisite pressure drop is obtained for maintain-ing the volumetric flow rate at predetermined magnitude.  The range of operation of the flow regulator is changeable by regulat-ing the size, dependent on the different angular positions of the regulating member, of the effective flow aperture between the regulating member and the flow passage.  The effective size of the regulating member is changeable in order to change the size of the effective flow aperture.  The regulating member comprises overlapping parts disposed to move so that the effective size of the regulating member is changeable.
