摘要： PURPOSE:To detect a leaked fluid easily, by changing electrostatic capacity by quantity corresponding to the difference between relative dielectric constants of air and the fluid when the internal fluid is leaked from machinery and the gap between capacitor electrodes is filled with said fluid. CONSTITUTION:When leakage was generated in the vicinity of the welded joint part 6 of piping 1, water leaked from the piping 1 is penetrated in a liquid permeable insulating member 11. The capacity C(F) of a capacitor constituted of a detection electrode 7, the member 11 and the piping 1 can be shown by the formula when dielectric constant is set to epsilon0, relative dielectric constant to K, the area of electrodes to S and the distance between electrodes to d. As a result, if the area S, the distance d and the dielectric constant epsilon0 are constant, the capacity of the capacitor is determined by the relative dielectric constant K of the substance filling the space between electrodes. If the substance between electrodes changes from air to water, the capacity C increase up to 80 times and the change in the capacity can be detected easily.

摘要： PURPOSE:To form many sound wave probes each of which has a highly accurate convex part by using a spherical surface of a bubble included in a specific material to form the original mold of a spherical lens having a prescribed shape. CONSTITUTION:In case of producing glasses such as quartz glass, a bubble having a proper shape size is selected from bubbles due to residual gas or the like generated in the glass. The quartz glass plate including the bubble is ground from one side up to a position near the equatorial surface of the bubble and finished with a prescribed size to form the male mold 9 of a spherical lens. Then, a material which is changed into glass carbon after sintering treatment is poured into the mold 9 and the material is preliminarily heated from the room temperature to 80 deg.C in air at the rate of 0.5 deg.C/min. Under said state, the glass carbon is peeled off from the mold and the obtained glass carbon is heated up to 1,300-2,500 deg.C, so that a completely glass-carbonated convex lens 12 can be formed.

摘要： PURPOSE:To perform transmission and reception in a lens composition surface with less reflection and high efficiency and obtain an image of high quality by sticking an organic high polymer film on the surface of an acoustic lens composition surface part. CONSTITUTION:The recessed surface of an acoustic lens 3 is coated with the high polymer film 11, which uses a vapor-deposited film of polyparaxylene preferably. Then, a film of 0.2mum in thickness is vapor-deposited under a vacuum uniformly without any pinhole and its thickness is controlled optionally. The acoustic impedance of this material is - 3X10 g/cm .sec and this value is almost an intermediate value between the acoustic impedance of crystal forming the acoustic lens 3 and the acoustic impedance of a sound wave propagation medium, so this material 11 is formed to a thickness equal to lambda/4 (lambda: wavelength of sound wave), thus obtaining a sufficient matching layer.

摘要： PURPOSE:To enhance an ON/OFF ratio, by forming two ultrasonic transmitting pulses by changing over two operation frequencies and forming one frequency out of the frequency band zone of a transmitting and receiving circuit. CONSTITUTION:A VCO oscillator 210 is controlled by a VCO control circuit 200 and, for example, repeats oscillation of 500MHz during a pulse width of 100nsec and that of 1,300MHz in other time regions to apply both oscillations to a power amplifier 230 through an analogue switch 220 turned ON and OFF by a pulse signal. This RF pulse electric signal is applied to a probe system 260 through a directionality coupler 240 and a matching circuit 250. The reflected signal through the circuit 250 and the coupler 240 is amplified by a receiving amplifier 270 having a band zone of 100MHz-1GHz and a component of 1,300MHz present in a base other than a reflected echo is removed. Output is amplified by an AGC amplifier 280 and converted to a video signal by a RF detector 290 and formed into an image signal by a sampling circuit 300. By this method, an ON/ OFF ratio can enhanced.
