Title: Measurement of insulation resistance for winding of ac equipment
Inventor: HAMAKAJI TAKESHI
IPC: G01R31/06
Filed: 1981-09-30
Abstract: PURPOSE:To always measure the insulation resistance value of windings of an a.c. equipment during the operation thereof by applying d.c. voltage between a casing thereof insulated with the earth and the bus GPT neutral point or the neutral point thereof. CONSTITUTION:A d.c. voltage E of about 50-100V is applied to the neutral point 4 of an a.c. equipment 2 from d.c. power source 5 during the operation thereof 2. Consequently, direct current I flows into the neutral point of the equipment as shown by the arrow. On the other hand, as a winding 3 is insulated but not perfectly, the direct current I leaks to a casing 8 from the winding 3 and flows to the earth through a switch box 9 for the equipment, a filter 6, a stray current cancellation circuit 10, an amplifier 11 and a winding insulation resistance indicator 12. After the value of the direct current I is measured, the indicator 12 calculates and display the insulation resistance value based on the value of the current I, the applied voltage E of the d.c. power source 5, the amplification factor of the amplifier 11 and the like.

Title: Microphone speaker system for voice conference
Inventor: SASADA TAISUKE
IPC: H04R3/02
Filed: 1988-06-22
Abstract: PURPOSE:To surely prevent howling and ring tone by using an echo canceller so as to reduce a bypassed voice signal from a speaker received by 2 microphones. CONSTITUTION:When an echo canceller 6 corrects an adaptive filter 52 only if a voice from a speaker 9 only is inputted to microphones 1a, 1b, the same waveform as that of a signal via a delay circuit DL4 is generated from a bypassed voice signal 9a. Thus, the two signals are subtracted by a subtractor 51 to make it possible that the transmission signal is made nearly zero. That is, the bypassed signal from the speaker 9 toward the microphones 1a, 1b when viewing from a transmission reception circuit 7 is nearly zero.

Title: Ratio analog-to-digital converter correcting non-ratio offset
Inventor: DONARUDO ARAN KAASU
IPC: G01D3/00
Filed: 1992-05-22
Abstract: PURPOSE: To provide a ratio A/D converter by subtracting a non-ratio offset, stored in a storage device from a digital output, in order to eliminate an offset before calculation of a ratio of an A/D converter so as to cancel a non-ratio error of the A/D converter. CONSTITUTION: This ratio A/D converter 20 generates a digital output DOUT and gives it to a non-inverting input of a non-ratio error offset block 28. An offset stored in a storage device 30 is fed to an inverting input of a ratio offset block 28. The offsets are used to cancel an error from the digital output DOUT of the ratio A/D converter 20, and a value without an error is outputted with respect to the non-ratio offset. This value is given to a system calibration block 32 that conducts system calibration. Thus, the non-ratio offset is obtained at first and then stored in the storage device 30 and subtracted from the digital output DOUT of the A/D converter 20 before compensation of the system gain and the ratio offset.

Title: Method and instrument for automatic discrete analysis
Inventor: SAGUSA TOSHIYUKI
IPC: G01N21/75
Filed: 1986-07-04
Abstract: PURPOSE:To save manpower for remeasurement by bringing a sample and reagents into reaction to obtain a measured value and retreat the sample automatically according to the defectiveness of the measurement results by a control device. CONSTITUTION:The sample of a specimen vessel 1 of a sample table 2 is put into a reaction vessel 18 of a reaction table 8 by a pipetting mechanism 6. The reagents 22, 23 are put into the reaction vessel 18 and are brought into reaction with the sample. The absorbancy of the sample is then measured by a spectroscope 12. The measurement operation is controlled by a controller 28. A systematic trouble (S) with which the measured values are continuously defective and a random trouble (R) with which the measured values are contingently defective are judged by the controller 28 at this time by the controller 28 and the cause thereof is indicated. The measurement conditions, etc., are corrected to the normal conditions, etc., and the measurement is made again in the case of the trouble (S). The sample is diluted with a diluent and the measurement is made again after the sample is diluted with a liquid diluent if, in the case of the trouble (R), the cause is, for example, the abnormally high activity of the sample. The sample is, therefore, automatically treated and the measurement is made again according to the cause of the defect of the measurement results. The time and manpower for the remeasurement treatment are thus saved.
