IPC: C10N40/22
Filed: 1981-12-17
Abstract: PURPOSE:To prevent the putrefaction of a metal processing oil with its emulsion kept intact, also with little increase in its temperature in the storage tank, by efficiently treating the oil under a specific condition. CONSTITUTION:A metal processing oil is partly drawn from its storage tank 1, being fed to a heating equipment 7 through a succession of the pipe 5 and the pump 6, followed by heating at 48-60 deg.C for a short time (for instance, at 50 deg.C for ca, 5-8min; at 60 deg.C for ca, 30-90sec). Subsequently, the resultant oil is returned through the pipe 8 to the tank 1. The cycle during which the total amount of the processing oil is subjected to heating treatment is (non)continuously repeated every 3-20 (pref. 5-15) hrs., said treatment being terminated after confirming that the number of aerobic bacteria in the oil has reduced to <=1X10<6>/ml. EFFECT:Free from any degradation in workplace environment, furthermore, with no selectivity for the strains of microorganisms to be killed, therefore also effective for anaerobic bacteria, sulfuric acid-reducing ones, etc. in addn. to aerobic bacteria.

IPC: F02D41/04
Filed: 1983-10-28
Abstract: PURPOSE:To make fuel injection valves operate within an area of good accuracy in regulating amounts of fuel by providing a control circuit which, when the fuel supply is stopped to a part of the cylinders, outputs to a fuel injection valve a fuel injection pulse in synchronization with a specific ignition signal. CONSTITUTION:When, in Steps 22 and 23, it is judged, from the number of rotations N and a negeative pressure Pb, as a specific area, then the fuel supply is stopped to the 2nd and 3rd cylinders, and the fuel injection pulse is read out (Step 25). When the reference timing signal SG becomes LOW and the ignition signal is inputted, the output processing is performed in Step 25. The fuel injection is usually performed in synchronization with the ignition signals of all cylinders, and, when the fuel supply is stopped to a part of the cylinders, it is performed in synchronization with only the ignition signal of an operating cylinder following each operating cylinder. In this way, the fuel injection valve can be operated in the area of good accuracy in regulating amounts of fuel, and, in addition to that, a good response of fuel supply is obtained.

IPC: B65G1/137
Filed: 1989-08-04
Abstract: PURPOSE:To have proper performance of stopping and moving by sensing the speed of an elevating table at certain time intervals, comparing the anticipated moving distance, when it is assumed that a deceleration command is given at each sensing time, with the distance to the object position, and by deciding the timing of deceleration command. CONSTITUTION:The moving speed of an elevating table 2 moving at a high speed toward the object position is sensed at certain time intervals. If the assumption is made that a deceleration command is given to this elevating table 2 at each sensing time, the anticipated moving distance until the elevating table 2 is decelerated to the target speed is calculated. This distance value is compared with the distance from the current position of elevating table 2 to the object position, which is used to decide the timing of deceleration command. Each current position in this case is calculated on the basis of the revolving speed of the drive shaft of an elevating table 2 driving motor 21 together with appropriate correction with the data given by a sensor installed in front of the object position.

Abstract: PURPOSE:To inexpensively obtain a speed detector having high reliability by detecting the speed of a motor by the secondary voltage and the secondary frequency of the motor. CONSTITUTION:The secondary voltage of a motor is stepped down to a suitable value. A sinusoidal AC voltage which has less waveform distortion is obtained through a filter 7. To discriminate the positive or negative polarity, it is inputted to a comparator 8, which outputs a pulse of frequency inversely proportional to the speed of a motor, and when it is inputted to a frequency-voltage converter 9, its output becomes a voltage signal of the characteristic of the curve (a). This is inputted to a level converter 10 to obtain the characteristic of the curve (b). This becomes the signal proportional to the speed of the motor.

Filed: 1992-07-30
Abstract: PURPOSE:To retrieve a candidate character with high efficiency without consuming much time by setting dictionary side character classification and recognition side character classification as separate ones based on the asymmetric property of error trend. CONSTITUTION:The same classification name is attached on classification conformed as the error trend in the dictionary side character classification and the recognition side character classification.
