Granted: 1991-05-07
Abstract: ABSTRACT          A force transducer having a vibratory member either a beam or a string and means for effectively isolating the vibratory member from its end mounts over the range of its operating frequencies to eliminate energy loss to the mounts. The axial stresses, either tension or compression, are directly transferred to the vibratory member to affect its natural resonant frequency.  Isolation at vibration frequencies is effected by the cooperation of combined isolator masses and isolator springs with the vibratory member.  The isolator masses comprise two bars extending from each end support of the vibratory member, each being coextensive with a portion of the support member.  The pairs of masses are axially separated.  The isolator springs comprise two single thin, spaced resilient members, each isolator spring connecting a single end support of the member and a single transducer end mount.

Title: Method of digital signal transmission
Inventor: TAKAI HITOSHI
IPC: H04L27/18
Filed: 1987-01-08
Granted: 1990-11-20
Abstract: ABSTRACT OF THE DISCLOSURE         A modulation method capable of high-speed or high-quality digital data transmission under a multipath fading transmissional, such as a radio transmission in an urban area of differential coding phase modulation and resides in the fact that the rate of change of phase varies, or the phase is discrete, but does not employ a phase transition waveform of a constant value in a time slot which is a smallest unit for transmitting one symbol of data as in conventional methods.  Phase transition waveforms in respective time slots which are spaced apart from each other by prescribed time slots are identical varying waveforms or discrete waveforms, and entirely shifted from each other by an amount according to the data transmitted.  A detecting method employed is a differential detection method using a delay line for delaying a signal for a time corresponding to the prescribed time slots.  In the presence of multipath propagation, a plurality of kinds of detected outputs are produced according to the multipath propagation, and the detected outputs are combined by a filter after the differential detection, producing a diversity effect for improving bit error rate characteristics.  This digital signal transmission method is capable of multiphase transmission and can increase spectrum utilization efficiency.

Title: Shared flexible rating of telecommunications calls
Inventor: AN CHUNGMING
IPC: H04M15/04
Filed: 1987-04-14
Granted: 1991-03-05
Abstract: SHARED FLEXIBLE RATING OF TELECOMMUNICATIONS CALLS            Abstract A method and apparatus for calculating charges for telephone calls in real time.  The operator assistance switch (16,18,20) connected to an originating telephone customer (50,52,54) recognizes that a call is one which requires an immediate calculation of charges.  Such calls include coin calls, calls from certain types of hotel/motel private branch exchanges, calls from customers who wish to be notified as to the amount of the charge for the call they are about to place, and calls from customers requesting a rate for a call to a particular destination. The operator assistance switch generates a message including the originating and terminating directory numbers and the type of the call.  The message is sent to a shared rating system (10) which uses the parameters sent in the message to calculate charges.  The shared rating system then sends a message, including the calculated charges, back to the operator assistance switch.  The customer, or the hotel/motel private branch exchange, is then notified of the amount of the charges. Advantageously, such an arrangement permits changes in the data used for calculating charges to be implemented easily and quickly because of the small number of shared rating systems whose tabular data (38) must be updated (28). Advantageously, changes in charging algorithms can be made independently of other program changes in operator assistance switches and can be made in one place for a number of different types of operator assistance switches.

Granted: 1991-07-09
Abstract: ABSTRACT OF THE DISCLOSURE    A method for determining the presence of an analyte in a sample suspected of containing the analyte is disclosed.  The analyte is a member of a specific binding pair ("sbp member") consisting of ligand and its complementary receptor.  The method comprises contacting, with a test solution containing said sample and a first sbp member analogous to said analyte, a contact portion of a piece of bibulous material capable of being traversed in at least one direction by said test solution by capillary migration.  The bibulous material contains a second sbp member capable of binding the analyte and the first sbp member.  The second sbp member is non-diffusively bound to the bibulous material at least at a portion thereof between the contact portion and a small situs on the piece separated from the contact portion.  The surface area of the situs is substantially less than that of the piece of bibulous material.  The situs is capable of binding the first sbp member not bound to said second sbp member.  Next, at least a portion of the test solution is allowed to traverse the bibulous material by means of capillary migration and thereby contact the situs.  The situs is examined for the presence of the first sbp member at the situs, which is usually indicated by the presence of a detectible signal. Such signal can be directly detectible, or the situs can be exposed to a signal producing means capable of interacting with the first sbp member to produce a detectible signal at the situs in relation to the amount of analyte in the sample.  The signal at the situs is distinguishable from signal detectible at portions of the bibulous material other than the situs.

Title: High efficiency coding apparatus
Inventor: KONDO TETSUJIRO
IPC: H04N19/65
Filed: 1988-05-18
Granted: 1991-09-03
Abstract: ABSTRACT      A high efficiency coding apparatus performs the control so that the amount of generated information does not surpass a transmission capacity of a transmission path when variable-length coding for varying a word length corresponding to a dynamic range.  With respect to a still block, distribution in which a movement amount is introduced is formed taking into account that frame-dropping processing is made to obtain the number of dynamic range occurrence.          Not only threshold values in the level direction for defining a word length but also movement threshold values for the frame-dropping processing are changed to control the amount of generated information.  As a result, the control of the amount of generated information is performed excellently without an increase in quantization errors.

Abstract: INCLINED CHISEL INSERTS FOR ROCK BITS                   ABSTRACT OF THE DISCLOSURE      An inclined chisel crested insert is disclosed for use on the gage row of a cone for a rotary cone rock bit.  The insert has different conical surfaces on opposite sides of the crown of the insert.  An elongated conically shaped gage cutting surface of the insert provides point or line contact with a borehole wall as opposed to a full surface contact with the wall as is common with state of the art flat sided gage row inserts.  This inclined chisel insert also has advantages over the symmetrical chisel type gage insert in that it is designed to provide increased crest length while providing the desired gage surface angle.  The conically shaped gage row inserts with offset chisel crest are less prone to frictional heating due to the point or line contact design.  As a result, the elongated conical gage cutting surface of the chisel crest insert minimizes gage insert wear and subsequent breakage by eliminating high cycle thermal fatigue.
