Title: Analog-to-digital conversion circuit
Inventor: KISHIKAWA SADASUKE
IPC: H03M3/02
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To provide an A/D(analog/digital) conversion circuit which can soften the required specification for a frequency band for an integrator and also can improve the S/N ratio and the accuracy of conversion. SOLUTION: In the feedback loop of an A/D conversion circuit of ΔΣ system, a band limit filter 60 is placed at the output side of a DAC 40. Thus, the higher harmonic components of an output signal S40 of the DAC 40 are suppressed and only the low frequency areas less than the cut-off frequency level are outputted. Then the subtraction result obtained to an analog signal Vin is inputted to an integrator 10 to generate an integration signal S10. The signal S10 is compared with a reference signal Sref by a comparator 20 and a binary signal S20 is outputted. Thus, the influence by the higher harmonic components is suppressed and the required specification is softened to the frequency band width of the integrator 10.  As a result, the S/N ratio and the operation accuracy of the integrator 10 are improved and accordingly the conversion accuracy of the A/D conversion circuit is improved.

Title: Leakage detector for conduit
Inventor: HIRATA MASARU
IPC: F17D5/06
Filed: 1979-11-30
Abstract: PURPOSE: To detect the leakage immediately by a device wherein a pair of conductive paths are formed along a conduit and change in resistance is detected upon the leakage of liquid into the space between the conductive paths.  
     CONSTITUTION: Voltage is always applied between conductive wires 6 and 7 from a leakage detector 10. When liquid within a conduit 2 is permeated into a heat insulator 3 upon leakage from the conduit 2, a part of the leaked liquid transudes beneath the conduit 2 by its weight or permeating force and enters into a space between the conductive wires 6 and 7. Therefore, electrical resistance between the conductive wires 6 and 7 is reduced due to the presence of the leaked liquid and there is produced current passing between the conductive wires 6 and 7. The leakage detector 10 detects the produced current and displays its value on a recorder 11. Also, an alarm 12 is operated to notice the leakage from the conduit 2.
