Inventor: ITOU HAJIME
IPC: C02F3/14
Filed: 1983-12-15
Abstract: PURPOSE:To nitrate and denitrify with a single apparatus by providing a valve which can be freely opened and closed to a gas passage communicating with an outlet opening in the axial direction of an agitator, operating continuously the agitator, and simultaneously opening and closing said valve at specified intervals. CONSTITUTION:The sewage is introduced into an aeration tank 12 from an inflow port 6, and a circulating flow in the direction shown by the arrow B is generated in the tank 12 by operating agitators 1. A gas is blown into the sewage by opening a valve 9, and hence an organic substance in the sewage is fermented and decomposed. Meanwhile, the amt. of oxygen dissolved in the sewage is detected by a dissolved oxygen meter 15, and the valve 9 is opened and closed when the detected amt. reaches the predetermined value. In this case, when the aerator is operated while closing the valve 9, the sewage is agitated and the fermentation by aerobic bacteria proceeds. And the concn. of the dissolved oxygen is rapidly decreased due to the consumption of oxygen. When the concn. of the dissolved oxygen reaches a specified lower limit, the valve 9 is opened to carry out aerobic nitration.

Abstract: PROBLEM TO BE SOLVED: To previously remove metal joined pipes which have possibilities of fractures and cracks in joined parts and partings in joined surfaces at the time of enlarging the metal joined pipes prior to the process of the enlargement of the pipes, by measuring the degree of discontinuity in the shapes of the joined parts, the degree of defects, and degree of changes in crystal structures prior to the enlargement of metal joined pipes, and comparing them with threshold values. SOLUTION: On a difference of level in an inner circumferential surface in the joined part of a metal joined pipe 10, ultrasonic probes 20a and 20b are brought into contact with the vicinity of the joined part between metal pipes 10a and 10b to make ultrasonic waves incident onto the surface vertically to obtain the difference of level in the inner circumferential surface from the time difference of reflected echoes. In addition, in the case of the presence of a defect in the joined interface, reflected waves from the defect are detected by the ultrasonic probes to obtain the presence or absence of a defect and its degree.  Furthermore, on the degree of changes in the crystal structure of the jointed part of the metal joined pipe 10, ultrasonic waves are made incident at an angle onto the joined interface to detect the transmitted waves by the ultrasonic probes to obtain the degree of changes in the crystal structure. Then these items of data are compared with threshold values to evaluate whether the metal joined pipe 10 is to be appropriately enlarged or not.

Filed: 1983-12-16
Abstract: PURPOSE:To gather various information in a ring automatically in the state where system cnfiguration is not known at all, by setting an address, which is recognized only by a ring monitor mechanism, as a frame destination address DA to transmit a frame. CONSTITUTION:A ring station R1 sets the address, which is recognized only by the ring monitor mechanism A, as the destination address DA and sets its own address as a transmission source address SA and sets an address recognition flag A in a frame status display area ST to ''0'' and transmits a frame 1. When receiving the frame 1, the ring monitor mechanism A stores the address SA as a logical address of a ring station 1 internally after confirming that the address recognition flag A is ''0'' and changes the address recognition flag A to ''1'' and flows the frame downstream. Though ring monitor mechanisms in the downstream see the address DA to receive the frame, they do not execute processings at all and allow the frame to pass though because the address recognition flag A is ''1''.

Title: Picture signal processing device
Inventor: OKAJIMA KENJI
IPC: G06K9/46
Filed: 1984-11-12
Abstract: PURPOSE:To obtain a picture signal processing device superior in noise resistance and capable of sharply detect the edge of an picture signal by preparing the difference function consisting of the difference between a two dimensional Gaussian function and the Gaussian function having the diversion greater than 4 times that of the former Gaussian function so that the integral value of the difference function reaches zero, and by providing the convolution section to apply convolution to an input picture regarding the difference function as a mask function and the zero detecting section to execute zero detection on the output from the convolution section. CONSTITUTION:Fig. (b) typically shows the output from the convolution obtained when a picture signal having a long edge is input, and as is obvious from this diagram, output 'O' (r) from the convolution proves to pass point zero on the edge just in the picture. Although on a sufficiently long edge, this convolution value goes to the value obtained by integrating the mask function over the half plane, this is proportional to the integrated value of mask function M (r) on the full plane. As mask function M (r) is prepared so that integral value goes to zero, the output from the convolution on the edge becomes zero. Accordingly, if zero point processing is next executed on the output from this convolution by zero point detecting section 6, edge detection in input picture is made possible.
