Title: Bubble/liquid level detector
Inventor: SUZUKI SHINZO
IPC: G01F23/296
Filed: 1984-09-20
Abstract: PURPOSE:To enable discriminative detection of bubbles and liquid level, by arranging an ultrasonic transmitting element for emitting two ultrasonic waves of varied frequencies and an ultrasonic wave receiving element for receiving it facing each other. CONSTITUTION:Ultrasonic wave transmission circuits 11 and 12 are provided to oscillate high and low frequencies respectively. An ultrasonic wave transmitting element 7a is provided to emit two ultrasonic waves of varied frequencies in a time-division fashion and an ultrasonic wave receiving element 7b provided facing 7a. Here, as the ultrasonic wave of low frequency receiving by the receiving element 7b is small in the attenuation for air but large for bubbles, discriminative detection of air and bubbles can be done. On the other hand, as the ultrasonic wave of high frequency is large in the attenuation for bubbles and air but small for liquid, discriminative detection of bubbles and liquid level can be done.

Title: Device for detecting abnormality of gas insulated switchgear
Inventor: KOYAMA HIROSHI
IPC: G01R31/00
Filed: 1991-08-07
Abstract: PURPOSE:To inexpensively detect the abnormality of an operating mechanism section with high sensitivity by closely adhering a sheet-like piezo-electric composite sensor to the internal surface of a metallic container near an operating mechanism so that the sensor can withstand shocks and detecting vibration waveforms when a mobile electrode is operated for opening and closing. CONSTITUTION:A sensor 10 made of a piezo-electric composite material is closely adhered to the internal surface of an earthing metallic container 1 near a mobile electrode 6 and its operating rod 8 and vibrations produced when the electrode 6 is operated for opening and closing are detected with the sensor 10. The sensor 10 is constituted by putting a piezo-electric composite material 10a prepared by mixing fine particles of a piezo-electric ceramic material with a high polymer material and formed to a sheet-like shape between electrodes 10b and 10c. Since the sensor 10 is formed to a flexible sheet and can be closely adhered to the internal surface of the container 1, the sensor 10 can withstand shocks produced when the electrode 6 are operated and is hardly influenced by outside noise. As a result, highly accurate waveform detection can be realized. In addition, since no resonance structure is used and this sensor can be applied to a wide band of frequencies, the cost of the sensor 10 can be reduced. The waveform detected by the sensor 10 is amplified by an amplifier 12 and measured by an instrument 14 after noise is cut off through a filter 13.

Filed: 1987-08-11
Abstract: PURPOSE:To make a ribbon-core type transformer small and lightweight, by winding a wire with a flexibility which has a rectangular cross section as a low-voltage winding in a transformer employing an amorphous alloy. CONSTITUTION:An annealed copper stranded wire is employed which is twisted from fine lines. The stranded wire which has a circular or oval cross section is then pressed from the upper and lower sides, and the right and left sides to form a winding with rectangular cross section. NOW, a high-voltage winding 2b is previously wound round a wound core by a toroidal winding machine, and the low-voltage winding 2a is then wound thereon. In that case, the low- voltage winding can be wound on each the space which is provided by the ring of the toroidal winding machine, which enables the spaces to be effectively used. Moreover, even if the size of the space is small, the winding can be wound thereon using a human power, jigs or a mechanical force because the low- voltage winding has a flexibility. As a result, a ribbon-core type transformer which is small and lightweight can be obtained, without the good characteristics of an amorphous alloy being degraded.
