摘要： PURPOSE:To simplify construction work by a method in which strusts for setting floor panels with ribs are set on the four corners and center of a base plate to make up a double floor and the floor panel and the strut have the same one-way cross sectional forms. CONSTITUTION:Struts 2 having coupling grooves by extrusion moulding are set on the four corners and center of a rectangular base plate 1 made of a flame-retardant and flexible material. A floor panel 3 having ribs 31 is formed by extrusion by equalizing the cross sectional forms of the ribs 31 and also of the coupling grooves of the strut 2. The plates 1 are closely placed on base floor and connected by the struts 2b of the four corners, and the floor panel 3 on which OA apparatus is to be set is placed on the plates 1. The system floor having excellent fireproofness can thus be easily formed.

摘要： PURPOSE:To enable accurate identification of a defective point of material to be inspected, by inserting and connecting a comparator between an ultrasonic wave receiver and a waveform display device to discriminate a reflection echo from a defect easily from a platinum noise. CONSTITUTION:A signal of a transmitter 1 is transmitted to an electromagnetically ultrasonic transducer 5, an ultrasonic wave 6 is transmitted into material 4 to be inspected and reflected waves 8 from a defect 7 are detected therewith 5. A detection signal thereof is applied to a receiver 2 for amplification thereof or the like to be inputted into a comparator 9, which compares an output voltage of the ultrasonic wave receiver 2 with a reference voltage determined and when it exceeds the reference voltage, a pulse signal is outputted and indicate as pulse F' within a waveform display device 3 to judge the presence of a defect. When the reference voltage is adjusted to set a threshold of the comparator 9 at about noise voltage level contained in the output voltage, a display can be obtained with excellent S/N ratio.

摘要： PURPOSE:To apply high-efficiency ultrasonic flaw detection (UT) to piping and fitting, etc. of complicated shape, by, for flaw detection of piping and fitting including a bent, displacing No.1 base and No.2 base in the axial directions of the piping and the fitting and swinging a swinging member. CONSTITUTION:In case when applying the UT along the periphery of a fitting 1b, a driving motor 7 is started to rotate a pinion and allow a running carriage 5 to travel along rails 2 and at the same time, a stylus module 43 is given with reciprocating motions within the specified range in the Y3 direction, this arrangement being made by driving of a driving motor 50. And, when, at this moment, the module 43 reaches a bend of an elbow 1a, a swinging member 22 is swung by driving of a driving motor 27 for allowing the module to run along the curvature of the elbow 1a. Further, a controlling apparatus controlling this series of motions stores preliminarily a shape of the pipe line as data and the controlling is performed basing upon the shape. By these arrangement, the UT can be applied automatically to pipings, fittings, etc. of intricate shapes, such as the piping 1 provided with the elbow 1a.

摘要： PURPOSE:To distinctly discriminate a reflected ultrasonic wave by receiving and transmitting ultrasonic waves by electromagnetic ultrasonic transducers independent of each other and separating a transmitter and a receiver. CONSTITUTION:Electromagnetic ultrasonic transducers 4a and 4b are connected to an ultrasonic test equipment B and are placed on the surface of a material 5 to be examined, and when a transmission pulse is inputted from an ultrasonic transmitter 1 to the transducer 4a, an ultrasonic wave 6 is transmitted into the material 5 to be examined and is propagated in the material 5 while repeating multireflection. the transducer 4b receives the ultrasonic wave 6 and receives a reflected ultrasonic wave 8 due to a defect 7 also. Since the ultrasonic wave 8 is propagated in the opposite direction of the ultrasonic wave 6, it is received by the transducer 4a also. Thus, the reflected ultrasonic wave is distinctly discriminated without an influence of the transmission pulse.
