Abstract: PURPOSE:To enable extremely certain detection of disconnection by reducing the effect of load variation at the time of disconnection, by respectively detecting change components of the positive-phase-sequence current and negative-phase-sequence current of a three-phase circuit and operating the same according to a specific formula. CONSTITUTION:The title apparatus is constituted of a fundamental wave filter 5, filters 6, 7 for detecting a positive-phase-sequence component and a negative-phase-sequence component, detection circuits 8, 9 for detecting a positive-phase-sequence change component and a negative- phase-sequence change component and a level judge circuit 10 for detecting the level of each change component. The phase currents Ia, Ib, Ic (all of which are a complex quantity) flowed to a distribution line 2 are applied to a fundamental wave filter 5 through a current transformer 3 and an auxiliary current transformer 4 and only fundamental waves are taken out. The positive-phase-sequence component I1 and the negative-phase-sequence component I2 are detected by the filters 6, 7 and the differences I1, I2 between the positive-phase-sequence current and the negative-phase-sequence current at the time of normality, and the positive-phase- sequence component I1 and the negative-phase-sequence component I2 from the filters 6, 7 are outputted from the circuits 8, 9. Hereupon, the operation of Qx=(DELTAI2/DELTAI1)(¦DELTAIx¦/2¦DELTAI2 ¦)<2> (where in x=a,b,c) is performed by an operation circuit 12 and the operation result is compared with the setting region of a setting part 14 by a comparator circuit 13 to output a disconnection alarm.

Abstract: PROBLEM TO BE SOLVED: To reduce the current consumption in the multi-stage variable amplifier circuit and to improve the linearity at an input intercept point and the gain. SOLUTION: The multi-stage amplifier circuit is configured by a constant current variable amplifier circuit 1 amplifying an input signal and current variable amplifier circuits 2, 3 amplifying further the signal amplified by the 1st variable amplifier circuit. An AGC voltage AGC is applied in common between a base and an emitter of an amplification factor control transistor(TR) Q14 of the constant current variable amplifier circuit 1 and between bases and emitters of amplification factor control TRs Q15, Q16 of the current variable amplifier circuits 2, 3, and collector currents of the TRs Q14, Q15, Q16 change exponentially with respect to the AGC voltage AGC changing linearly. A current proportional to a collector current of the TR Q14 flows to TRs Q1, Q4 and the gain PD (dB) of the constant current variable amplifier circuit 1 changes linearly with respect to the AGC voltage AGC.

Filed: 1983-04-30
Abstract: PURPOSE:To prevent leaching-out of salt efficiently, by applying a specified water-soluble polymer to salt-containing soil to form a water-impermeable layer in the ground. CONSTITUTION:An aqueous solution containing 0.01-30wt% water-soluble polymer which is insolubilized by an alkali metal salt (e.g. a mixture of polyacrylic acid and polyacrylamide in the blend ratio of 1:100-100:1 by weight) is sprinkled on soil which contains an alkali metal salt such as NaCl so that the solution may penerate into the ground and a water-impermeable layer may be formed by aggregation of the polymer under the action of the salts in the ground. EFFECT:Harmful salts in the ground surface are consumed in aggregation reaction of the water-soluble polymer leading to reduced concentration and leaching- out of harmful salts from the depths is prevented by formation of a water-impermeable layer at an appropriate depth.

Title: Vibration gyro
Inventor: SAHORI DAISUKE
IPC: G01C19/5663
Filed: 1988-03-30
Abstract: PURPOSE:To improve the assembly operability by connecting a piezoelectric element to respective electrodes by utilizing support shafts for supporting a vibrator, and then connecting payoff end parts of the support shafts to a flexible printed board and connecting them directly to an external circuit. CONSTITUTION:A support shaft 3A supported pivotally on a vibration body 1 is inserted into the hole 2A' of the piezoelectric element 2A and adhered and fixed to the flank 1A of the vibration body 1 through an extremely thin adhesive layer to generate the state of electric coupling between the surface 1A of the vibration body 1 and piezoelectric element 2A. Further, the support shaft 3A and the opposite surface of the piezoelectric element 2A are made conductive and coupled by using a conductive adhesive 7A. Consequently, the electric coupling with the piezoelectric element is led out not through a lead wire. Support shafts 3B and 3D are exactly the same and three surfaces of a vibration gyro main body are completed. The support shaft 3C needs to be coupled electrically with the vibrator 1, so no insulating member is used and a fitting member 4C is pressed in the hole 1C' in the flank 1C of the vibrator 1 directly to generate an electric coupling state.
