Title: Non-destructive inspection by frequency spectrum  resolution
Inventor: SUGIYAMA SAKAE
IPC: G01N29/12
Filed: 1981-06-18
Granted: 1984-06-26
Abstract: Abstract:        A method of inspecting non-destructively a specimen for examining the presence or absence of a defect in the specimen, in which an ultrasonic wave is emitted from a probe and a reflected wave from the specimen is received by the probe whose output signal is processed to determine the presence or absence of the defect.  The signal processing includes steps of extracting character-istic parameters from a frequency spectrum of the ultra-sonic echo and comparing the extracted parameter with corresponding experimentally or theoretically determined values.  The invention makes it possible to automatically determine discriminatively whether the reflector of the ultrasonic echo is a configured portion, a weld boundary or a defect of a specimen to be inspected.

Abstract: CLOCKED IGFET LOGIC CIRCUIT        Abstract A clocked IGFET serial decoder circuit has a precharge transistor with its conduction channel connected between a VDD supply and an output terminal, a string of transistors with their conduction channels connected in series between the output terminal and a switch ground node and a ground switch transistor with its conduction channel connected between the switch ground node and a VSS supply.          The gates of the transistors of the string receive input signals from clocked input buffers which bias the gates at VDD during the precharge interval when the precharge transistor is ON and the ground switch transistor is OFF.          This allows the parasitic capacitances at the junctures of the transistors in the string to become substantially charged during the precharge interval and thus prevent rapid charge sharing at the output terminal when the circuit is enabled.

Abstract: ABSTRACT OF THE DISCLOSURE      A separable slide fastener  comprisies a pair of warp-knit stringer tapes each having a pair of webs with a wale-free region therebetween,  which are interconnected by a connector thread   extending across the wale-free region at longitudinal intervals, each wale-free region being provided for receiving a respective chain of thread loops for attaching the respective stringer tape to a fabric.  A pair of rows of coupling elements is arranged such that each row is mounted on opposite longitudinal edges of a respective one of the stringer tapes.  The rows are taken into and out of interdigitating engagement by a slider movable along the rows of coupling elements.  the stringer tapes have at one end thereof a separable bottom end stop.  A respective reinforcement member is mounted on each of the stringer tapes at the one end thereof and connected to the separable bottom end stop.  The reinforcement member extends between the tape webs across  the respective wale-free region and includes means adjacent to the wale-free region for anchoring an end of the chain of thread loops on the reinforcement member against displacement thereof.  The anchoring means comprises a projection extending from a body of the reinforcement member in a direction away from the stringer tape and located substantially in alignment with one of the webs of the stringer tape.  The projection serves to prevent the end of the respective loop chain extending around the reinforce-ment body from being displaced off the body.

Abstract: LINEAR FREQUENCY MODULATOR FOR FM/CW RADIO ALTIMETER    Abstract of the Disclosure A linear frequency modulator for a varactor tuned transis-tor microwave oscillator used in an FM/CW radio altimeter where the oscillator-frequency v. varactor bias characteristic is non-linear. A linear triangular wave is converted by means of a function gen-erator to the non-linear wave required for varactor bias to cause linear frequency modulation of the oscillator.  linearity of modu-lation is tested by measuring variations in the period of a cali-bration signal derived from a delay line.  Variations in the cali-bration signal period, sampled at times corresponding to low fre-quency and to high frequency outputs of the oscillator, are used to control the function generator for altering the form of the varac-tor bias wave in portions thereof corresponding to low frequency and to high frequency outputs of the oscillator.

Abstract: SYNC SUPPRESSION SCRAMBLING OF TELEVISION           SIGNALS FOR SUBSCRIPTION TV                          ABSTRACT          In order to provide higher efficiency of secu-rity in sync suppression scrambling of subscription TV signals, the signals are encoded with a timing pulse having a selected time delay relationship with the sup-pressed horizontal sync intervals of the TV signals.          The timing can be implemented digitally by selecting a plurality (e.g., 12) of different timings.  The timing can also be dynamically varied.  The TV signals are descrambled by restoring the sync pulses at only those receiving stations authorized to receive the premium subscription programming which have circuits for gener-ating restoring pulses with the selected time relation-ship upon reception of the timing signals.  Accordingly, the use of unauthorized descramblers, which are insensi-tive to the timing signals or do not provide the restor-ing pulses in proper time relationship, is discouraged.

Abstract: ABSTRACT OF THE DISCLOSURE   A tubular apparatus is assembled of inner and outer tubes which are connected at spaced locations along their length. After heat treatment and other processing steps, either the inner or outer tube is heated to reduce its yield strength and then stretched beyond its yield point but not beyond the yield point of the other tubular. The heat source is removed so that the stretched state is maintained.  The tubular apparatus is thus prestressed with the inner tube under compressive prestressing when the inner tube has been heated and stretched, and the inner tube under tensile prestressing when the outer tube hasbeen heated and stretched.
