Title: Method and apparatus for performing ultrasonic flaw detection
Inventor: HORIGOME HIDEKAZU
IPC: G01N29/34
Filed: 1991-11-12
Abstract: Abstract of the Disclosure According to a method of performing ultrasonic flaw detection, a pulse signal is output to an ultrasonic probe attached through an ultrasonic wave propagation medium to an object to be tested, a reflected wave of the ultrasonic wave incident on the object is received by the ultrasonic probe to obtain an echo signal.  The carrier frequency of the pulse signal is set so that the peak frequency of the echo signal becomes a predeter-mined frequency, and then the cycle count of the pulse signal is set so that the frequency bandwidth of the echo signal becomes a predetermined bandwidth.  A defect present in the object is detected in accordance with the echo signal output from the ultrasonic probe.     According to an apparatus for performing ultrasonic flaw detection, an ultrasonic transmitter transmits a pulse signal having a designated carrier frequency and a designated cycle count to an ultrasonic probe.  An ultrasonic receiver receives the echo signal output from the ultrasonic probe.  The peak frequency and the fre-quency bandwidth of the echo signal received by the ultrasonic receiving unit are detected by a signal anal-ysis unit.  A transmission control unit designates the carrier frequency and the cycle count of the pulse sig-nal output from the ultrasonic transmission unit so that the detected peak frequency and the detected frequency bandwidth become a flaw detection condition peak frequency and a flaw detection condition frequency bandwidth, respectively.

Title: Medical member and method of manufacturing the same
Inventor: OGAWA KAZUFUMI
IPC: B05D1/18
Filed: 1992-01-24
Abstract: A medical member having active hydrogen groups such as hydroxyl, amino or imino groups at its surface, is dipped, either directly or after formation of an inner layer on its surface, into a solution. The solution is prepared by dissolving a surface active material, e.g., CF3 (CF2)7 (CH2)2SiC13 in a non-aqueous solvent. A dehydrochlorination reaction is brought about between active hydrogen groups at the surface of the member and SiCl groups of the surface active material, thus producing bonds of CF3 (CF2)7 (CH2)2Si (O-)3 over the entire surface. A fluorine-containing monomolecular film is formed, which is chemically (or covalently) bonded to the member surface and has a thickness at the nanometer level.      Since the chemically adsorbed film is covalently bonded to the member or inner layer, it is chemically stable and difficult to separate. Excellent medical members can be obtained When the invention is applied to an artificial tooth, a joint, a bone, a blood bag, a catheter, a blood transportation tool, a dialysis equipment part, an operation thread, a medical implant and an operation tool.

Title: Isotopic diamond coated products and their production
Inventor: TIEMANN JEROME J
IPC: C30B25/02
Filed: 1992-08-13
Abstract: ISOTOPIC DIAMOND COATED PRODUCTS      AND THEIR PRODUCTION                      ABSTRACT OF THE DISCLOSURE Broadly, the-present invention is directed to a diamond product comprising a core of diamond containing at least about 1 wt-% 13C and an epitaxial diamond coating on said core containing at least 1 wt-% less 13C than is contained in said diamond core. The diamond core will have a lattice parameter that is smaller than the lattice parameter of the diamond coating. When the coating is forced to grow epitaxially so that it must have the same lattice constant as the diamond core, she coating will be placed under compression. Since 13C diamond has the smallest lattice parameter known and the lattice parameter of diamond is a function of isotopic composition, the diamond core should contain more 13C than is contained in the coating in order for the coating to be placed under compression. Accordingly, the diamond core can be composed of natural or synthetic diamond having a natural isotopic composition and the coating can be 12C or 13C. Alternatively, the core can be 13C and the coating 12C. When mixtures of isotopes comprise the core and/or coating, their composition should vary by at least 1 wt-% 13C with the higher incidence of 13C isotope being located in the core.

Abstract: A boat trailer  comprises a rectangular rear frame section and a forwardly extending hitch bar.  On the rear frame section is mounted a pair of  longitudinally extending bunks onto which the boat can rest during transportation to avoid pressure points.  Inside the bunks toward a longitudinal centre line of the trailer is provided two pairs of roller assemblies which can be raised to a position to hold the boat above the bunks  for  loading  and  unloading  and  can  be  lowered  to a position  in  which  the  boat  is  lowered onto  the bunks  and separated from the  rollers  to avoid pressure points during transportation.  The roller assemblies are commonly actuated by a linear actuator arrangement at the front of the hitch bar.          Each  roller  assembly  includes  four  rollers  independantly pivotal to allow the rollers to follow the contour of the boat.          At a forward end of the hitch bar is mounted a security leg which can extend along the underside of the hitch bar or can be moved downwardly to a deployed position in which it raises the hitch bar above the normal hitch position so as to incline the trailer  rearwardly  and  can  be  locked  in that position to prevent the hitch being used.
