Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To maintain proper accuracy, and prevent the occurrence of an overturn or the like at the time of a precast concrete slab erection work by applying the constitution that the lower side of a precast concrete slab and the floor of a story immediately below a story for erecting the precast concrete slab are jointed to each other with chain having a turnbuckle and, then, the chain is given tension. SOLUTION: An insert 2 is preliminarily driven into the lower end of a precast concrete slab, and a scaffolding insert 3 is as well preliminarily driven at the time of placing concrete for a lower story, thereby suspending the precast concrete slab. Also, an eye bolt 5 is fitted to the scaffolding insert 3 in advance. When the precast concrete slab is placed on a support, a chain 6 is fastened to a chain mate 4. Thereafter, the chain 6 adjusted in length suitable for a hook 8 above a turnbuckle 7 is jointed to the eye bolt 5. Then, the turnbuckle 7 is turned to apply tension to the chain 6. Also, the precast concrete slab is detached from a crane and, then, erected at the prescribed position after fine adjustment. Thereafter, the turnbuckle 7 is turned so as to give tension up to a value within a chain safety load.

Title: Determination of thickness of ferromagnetic substance deposited on nuclear fuel rod
Inventor: JIYON ARUBO KAABUINEN
IPC: G01N27/90
Filed: 1994-05-11
Abstract: PURPOSE: To improve the accuracy in eddy current test for measuring thickness of a corroded layer formed on the surface of a nuclear fuel rod cover where a ferromagnetic material is supposed to exist. CONSTITUTION: Errors in a thickness measuring value caused by the magnetic permeability of a ferromagnetic material is quantified by measuring the complex impedance of a probe. A plurality of calibration samples having known thickness and known magnetic permeability are placed between a probe a sensor excited by a predetermined frequency and the surface of a fuel rod without corrosion to obtain a characteristic diagram of the complex impedance of the probe. Next, the complex impedance of the probe excited by the above mentioned frequency is measured when the probe approaches the fuel rod having a corroded layer of unknown thickness and unknown magnetic permeability to plot on the characteristic diagram. Errors can be determined by the comparison of the calibration points with the measuring data points.

Title: Water level abnormality detector
Inventor: WADA MINORU
IPC: G01F23/00
Filed: 1980-07-17
Abstract: PURPOSE: To detect abnormal raise of water level exactly and to enable efficient pumping operation, etc. by providing electric power detector which detects electric power of main circuit of power generator-motor at pumped storage power station plant and by effecting the detection with output of the detector.  
     CONSTITUTION: When pushing down is instructed while pumping up operation or phase modifying operation, compressed air is sent into draft 3 to push down water level at the moment contact 7 closes. When the water level lowers entirely, water level detector 5 deenergizes water level detecting relay 6 and then relay 8 is activated via contact 6b, and contact 9a-2 closed by relay 9 at the moment contact 8a is closed. On the other hand, deenergization of relay 6 turns system power source 13 in and generator-motor 4 turns runner 2. If water level abnormally raises and touches with runner 2, electric power of system power source 13 rapidly increases, and relay 18 causes contact 18a close and relay 19 is activated to output abnormality detection signal.

Title: Stabilizer and control method thereof
Inventor: UMEDA HIROTAKA
IPC: B60G17/02
Filed: 1989-04-17
Abstract: PURPOSE:To improve riding comfortableness by providing a connection part capable of controlling the angle of rotation or oscillating angle between a torsion-bar and wheels in a stabilizer for vehicle. CONSTITUTION:A link 10 having a connection part A is provided between an arm 1b and a stabilizer-link 3, and the upper and lower parts of the stabilizer-link 3 are formed into oscillating rotary couplings B, C. In this constitution, for example, when only one side of a lower arm 4 moves up and down, the coupling C is moved upward and downward. At this time, because the connection part A of the link 10 is so constructed as to be freely rotated by a rotatable angle alpha, an angle beta between the arm 1b of the stabilizer 1 and the link 10 is changed in a certain range of up-and-down motion of the coupling C, and the arm 1b does not turn around a shaft line 6, thus the stabilizer is capable of functioning. When the angle alpha is exceeded by the up-and-down motion, the stabilizer functions. In this constitution, the function of the stabilizer is reduced, and improved riding comfortableness can be obtained.

Abstract: PURPOSE: To provide device and method for plotting a curve by making the curve into a raster while using a table for data reference. CONSTITUTION: The curve is segmented so as to be approximated by series of straight line segments which have an almost equal length not exceeding the length of two picture elements. When the line segment crosses the horizontal axis of picture elements, the distance from a point, where the line segment crosses the horizontal axis, to the central point of these picture elements is determined by using the table for data reference. A pointer for addressing the table for data reference is the total of data values of three index tables weighted so as to exclude multiplication required for the table for data reference, and the index table is addressed by using three index pointers.  Concerning the index table, the reduction of picture element resolution is programmed as well, and this table is made non-linear as well so that a lot of data entries can exist in the area where a round error caused by resolution reduction becomes maximum. When the line segment crosses the horizontal axis on the left side of center of picture elements, the logical state of these picture elements is changed.

Title: Controlling method of radar and apparatus therefor
Inventor: WATANABE HARUHIKO
IPC: G01S13/70
Filed: 1989-04-18
Abstract: PURPOSE:To prevent the lowering of precision in detection of a distance to a target by computing a transmission pulse width minimizing an overlap of a transmission pulse with a reception pulse and by outputting a previously- outputted distance error to a distance filter when the amount of the overlap is larger than a limit. CONSTITUTION:At a time t-1, a transmission pulse width minimizing the amount of an overlap of a transmission pulse 4 with a reception pulse 6 is computed and outputted to a transceiver 7. When the overlap of the transmission pulse 4 with the reception pulse 6 is detected, a distance error is corrected by the amount of the overlap. In the case when the overlap exceeds some prescribed amount, the previous value is outputted as the distance error and thereby an effect on a distance filter 11 is prevented. Thereby it is possible to compute a subsequent transmission pulse width correctly, to prevent a break of detection of a target body 1 and to improve a tracking performance.
