Filed: 1978-04-26
Abstract: PURPOSE: To prevent the deviations of right and left recording characteristics which occur in reproduced sound at the reproducing by recording the sum of the right and left audio inputs to one of the two magnetic tracks of a film and recording the difference of the right and left audio inputs to the other.  
     CONSTITUTION: If the audio inputs obtainable with a right microphone 1 and a left microphone 2 are let to be R, L respectively, a recording head 11 is driven by the audio signal of R + L owing to the effect of an adder 7 and a recording head 12 is driven by the audio signal of R - L owing to the effect of a subtractor 8. As a result, a magnetic track 14a is magnetized in compliance with the audio signal of R + L and a magnetic track 14b is magnetized in compliance with the audio signal of R - L with advance of filming. Hence, if this cine film 14 is reprduced with a stereo sound projector, a right speaker 28 is driven by the audio signal of 2R and a left speaker 29 by the audio signal of 2L respectively and therefore no deviations of characteristics occur in the reproduced sound.

Title: Piezoelectric vibrator
Inventor: KANBARA MASAHARU
IPC: H04R17/00
Filed: 1979-04-26
Abstract: PURPOSE:To improve insertion loss of the display wave operation by laminating piezoelectric material layers and electrode layers alternately by screen printing. CONSTITUTION:Mask 31 having pattern 32 is put on base stand 30 of the piezoelectric material, and slurry of piezoelectric porcelain materials is coated onto pattern 32 by spatula 33. After this slurry is dried, the electrode layer of sliver palladium paste is applied. These processes are repeated to constitute lamination material 10. This lamination material 10 is cut in parallel with plane A-A into a desired size and is calcinated. A DC voltage is applied across respective electrodes connected alternately to polarize the piezoelectric material. At this time, since piezoelectric material 10 is divided into thin layers by electrodes, the applied voltage may be comparatively low. Then, insertion loss becomes small because the bulk wave is used in the operation mode.

Filed: 1993-03-11
Abstract: PURPOSE:To enable higher precision fuel injection control by way of precisely finding difference of a residual fuel amount in a fuel system regardless of a rotational region and whether it is of a direct injection type or not. CONSTITUTION:Fuel is delivered with pressure to a fuel injection nozzle 4 provided on a diesel engine 3 from a fuel injection pump 1. On the fuel injection nozzle 4, a pressure sensor 47 for its closing valve pressure detection is provided. An ECU 71 computes a residual fuel amount in a fuel system in accordance with closing valve pressure detected by the pressure sensor 47, and it computes deviation of the residual fuel amount. Additionally, the ECU 71 performs fuel injection amount control by driving and controlling the fuel injection pump 1 in accordance with a target injection amount corrected by the residual fuel amount deviation. Accordingly, a more proper residual fuel amount is found from the closing valve pressure, and moreover, more proper residual fuel amount deviation is found. Additionally, at the time of fuel injection each time, influence of the residual fuel amount is properly removed from the target injection amount, and fuel injection control is carried out without being influenced by time- serial change of the fuel injection nozzle 4 and others.
