Title: Pressure test method by applying tension to pipe through multistage packing
Inventor: YOSHIKAWA YUUZOU
IPC: G01N3/12
Filed: 1977-12-05
Abstract: PURPOSE: To eliminate deformation or the like of the pipe end, by sealing a test pipe comprising more than two packings in the head body, and keeping the pipe from slipping with a frictional force applied by a packing sealed by other pressure.  
     CONSTITUTION: A test pipe 8 is sealed by packings 25 to 27 built in a head body 3, and is also sealed with a other liquid pressure from a pressure supplying port 40. When a pressure builds up in the pipe 8, as the reaction force thereto, a main ram 7 attempts to retreat by the compressed amount of the fluid in a main cylinder 6. Then, the body 3 attempts to move due to the area difference between the outside diameter of pipe 8 and outside diameter of correction ram 2, but the body 3 and pipe 8 do not move relatively because the pipe 8 is held by packings 25 to 27. At the time of pressure test, since the pipe 8 is held so as not to slide in the axial direction, the pipe end is not hit against the body 3, so that the pressure test may be performed without causing damage on the pipe end and body 3.

Title: Processing of image
Inventor: NAGASHIMA SUNAO
IPC: B41J2/44
Filed: 1987-06-11
Abstract: PURPOSE:To prevent a line on a border part between images from occurrence, by a method wherein after image memory over a plurality of divided mutual adjacent scanning regions are stored in memory, the image data stored in the memory are processed by an error diffusion method. CONSTITUTION:When a form of a diffusion matrix is to be considered, data of one scan content, for instance, data of a region (a) are stored in memory, and signal processing direction conversion of main scanning and subsidiary scanning is performed. That is, after a signal is converted by using the memory, binary processing of error diffusion or the like is performed, and reverse signal conversion is performed by using the memory again. By performing such a process as abovementioned, image data partially read can be treated as a sheet of continuous images, and a problem of an 'line' having been generated on the boundary between the regions abovementioned can be solved.

Title: Supersonic monitor for nuclear reactor
Inventor: SASAKI KEIICHI
IPC: G01B17/00
Filed: 1982-08-27
Abstract: PURPOSE:To easily detect an abnormality in a gap between the upper mechanism of the core of a reactor and an aggregate of fuel and improve the accuracy of detection by such an arrangement wherein a supersonic generator and receiver is positioned at the same place and caused to generate waves plural times and reflected signals from a supersonic reflector are synchronously added up and then averaged waveforms are to be monitored. CONSTITUTION:A supersonic generator and receiver 10 is caused to oscillate (n) pieces of supersonic wave. Oscillated supersonic waves are reflected by a supersonic reflector 14 through a gap between a reactor core unit 4 and an upper mechanism 5 of the reactor core unit and they are received by the supersonic generator and receiver 10. The received supersonic waves become such waveforms which are composed of a received signal S of which phase is fixed at all times and random high frequency noises inherent to a nuclear reactor, in other words S1- Sn. For instance, the waveform of a received signal by the first oscillation becomes S+S1 and that of a received signal by the (n)th oscillation becomes S+Sn. By such an arrangement wherein reflected wave signals of n times from the supersonic generator receiver 10 are synchronized in time, the phase of received signal S is adjusted to that of high frequency noise S1-Sn and they are added up and averaged, random high frequency noises are reduced although the level of signals from the supersonic reflector is not changed and S/N ratio is improved and a signal Sr can be obtained.
