Title: Flux vector operation unit for induction motor
Inventor: MINAMOTO MASAHIRO
IPC: H02P27/16
Filed: 1985-12-06
Abstract: PURPOSE:To obtain the high precision of flux arithmetic operation even at low speed by storing a correction signal in a low speed region, in which correction operation is impossible, and continuously correcting flux arithmetic operation by the memory signal while correcting the memory signal in response to a temperature change. CONSTITUTION:Motor revolution (n) is inputted to a microcomputer 100, and the microcomputer check for low speed. Current-model correction quantity 1/T2 is arithmetically operated so that a deviation between a flux set point *and an actual value PHI reaches zero at high speed. The value of 1/T2 is stored in a first region M1 in memory 102. A motor temperature ts is inputted, and stored in a second region M2 in the memory 102. Correction is continued by the value of the first region M1 in the memory 102 immediately before correction operation is stopped at low speed. When the alteration of the motor temperature is decided, the current-model correction quantity (the contents of the first region M1 in the memory 102) is corrected in response to a tempera ture change.

Title: Oxygen sensor
Inventor: SHIMOYAMA HIROMI
IPC: G01N27/12
Filed: 1984-12-27
Abstract: PURPOSE:To improve the fuel cost, output and exhaust gas emission characteristic of an internal-combustion engine by allowing particles having high adsorptivity to exist mixedly in a protective layer of a sensor part thereby realizing a stable air-fuel ratio control operation of the internal-combustion engine for a long period of time. CONSTITUTION:An inside electrode 12 and outside electrode 13 consisting respectively of platinum are deposited to part of the inside surface and outside surface of a ceramic pipe 11 and platinum is further deposited by evaporation on the outside surface side thereof to form a catalyst layer 14. The particles having high adsorptivity, for example, gamma-alumina particles 16 are made to exist mixedly in the protective layer 15 covering the layer 14. The lead component contained in the exhaust gas is then adsorbed by the particles 16 when said component penetrates the layer 15 in the case of using a leaded gasoline as the fuel for the internal-combustion engine. The poisoning of the layer 14 by the lead is thereby effectively suppressed and the delay in the generation of electromotive force is prevented. The response delay from lean to rich by the signal from the oxygen sensor is thus prevented.

Title: Magneto-resistance effect type head
Inventor: KANAI HITOSHI
IPC: G11B5/39
Filed: 1988-10-31
Abstract: PURPOSE:To suppress the generation of the Barkhausen noise at the time of reproducing by arranging a shielding body to pinch a head main body only in a part facing an MR (magneto-resistance effect) element, and pinching a pullout magnetic layer and a permanent magnet by non-magnetic layers. CONSTITUTION:Shielding bodies 21 and 22 are approximately in a size corresponding to an MR element 3, face the MR element of a head main body 2, and they are arranged by vertically pinching the MR element 3 through a gap layer 13. A non-magnetic layer 23 made of SiO2 and Al2O3 vertically pinches the part other than the MR element 3 of the head main body 2, namely, pullout magnetic layers 4 and 5 and a permanent magnet 6. That is, since the shielding bodies 21 and 22 are farther separated from the permanent magnet 6, a magnetic flux from the permanent magnet 6 flows not into the shielding bodies 21 and 22 but solely into the pullout magnetic layers 4 and 5. Consequently, the magnet from the permanent magnet 6 effectively flows into the MR element 3, and the magnetic field is sufficiently impressed to the MR element 3. Thus, the magnetic zone in the MR element 3 is stabilized, and the Barkhausen noise is not generated at the time of reproducing.

Abstract: PURPOSE:To simplify the filter estimation operation by estimating a filter coefficient of an equivalent noise generation filter while a maximum value obtained through the retrieval of a correlation coefficient between outputs of a sound signal receiver and plural noise receivers at no sound is being corrected. CONSTITUTION:Equivalent noise generation filters 30-1-30-P have impulse responses h1(t)-hp(t) of a transmission line subject to noise between P sets of noise sources and sound signal pickup receivers, the filters receive mainly the noise generated from any of the P-set of noise sources, add the noise superimposingly and the result is subtracted from the output of a delay circuit 2 to erase the noise. In estimating the filter coefficient of the equivalent noise generation filter, detected waveforms Su(t) and Sn(t) are obtained from the noise at no sound and the noise from noise source, and a noise erasure residual waveform U(t) is obtained by a correlation coefficient calculator 56, an autocorrelation coefficient calculator 57, a coefficient decision device 58, an equivalent noise generation filter 59 and a subtractor 60 based on the detected waveforms. Then one filter coefficient minimizing the waveform is estimated and the process is repeated until the noise U(t) reaches a prescribed level or below. Thus, the required operation quantity required for the estimation of the filter coefficient is reduced.
