Title: Method for uniformly mixing whisker and metal powder
Inventor: TSUKUDA MASAHIRO
IPC: C22C47/14
Filed: 1984-05-28
Abstract: PURPOSE:To enable perfectly uniform mixing even if there is density difference by eliminating the breakage of whiskers, by a method wherein ultrasonic vibration is applied to the whiskers in an org. solvent to unravel the entanglement thereof and, thereafter, a metal powder is added to said whiskers to perform stirring. CONSTITUTION:A predetermined amount of an org. solvent such as ethyl alcohol is stored in a stirring bath 1 and whiskers comprising SiC, Si3N4, Al2O3 or B4C are added to and mixed with said org. solvent. The resulting mixture is recirculated between a recirculation pipe 3 and the stirring bath 1 by a pump 4 and ultrasonic vibration is applied during recirculation from an ultrasonic horn 5 to unravel the entanglement of the whiskers. Subsequently, a stirrer 2 is rotated at 60-1,000rpm to perform uniform mixing while the aforementioned mixture is recirculated between the recirculation pipe 3 and the stirring bath 1 and the obtained mixture is discharged onto a filter 11. Next, an air pump 10 is operated and only the org. solvent is sucked and filtered from the mixture at a high speed.

Title: Differential gear with differential limiting-mechanism
Inventor: HIRAMATSU TAKEO
IPC: F16H39/40
Filed: 1985-05-21
Abstract: PURPOSE:To enable an appropriate limitation of a differential mechanism in response to operating conditions by supplying the discharge oil pressure from an oil pump interposed between the input shaft and the output shaft of the differential mechanism to a clutch mechanism. CONSTITUTION:If any rotating speed difference occurs between a front wheel output shaft 5 and a rear wheel output shaft 4, the rotating speed difference is restricted in response to the rotating speed difference by a differential limiting-mechanism 13. Further, the differential limiting-mechanism 13 is brought into a nonoperable state by controlling the discharge pressure of an oil pump 14 by means of relief valves 26 and 27 so as to be less than a prescribed value, and allowing the rotating speed difference by means of a center differential gear 6 to prevent the braking phenomenon. Furthermore, by setting arbitrarily the degree of throttle of orifices 30 and 31 which are an oil pressure control means 280, the differential limitation can be automatically carried out.

Signals of only frequency components necessary for detecting the heart rate among the inputted signals are passed here and, next, differential amplification is carried out by a differential amplifier 16 to amplify parts with remarkable changes of signal waveforms of the cardiac potential 2. Following that, the output signals are compared with the reference potential at a comparison calculation circuit 17 and obtained ON-OFF signals synchronized with the cardiac rate are inputted into a central control part 22 to calculate the cardiac rate per one minute.  Power supply to first and second electric heater parts 9, 10 is controlled according to the deviation of the electrode temperature against the reference temperature.

Title: Automatic measuring method for numerical controller
Inventor: SAITOU KIMIO
IPC: G05B19/18
Filed: 1988-05-06
Abstract: PURPOSE:To take an automatic measurement fast with high accuracy by cleaning a position deviation quantity to zero or stepping it down when a sensor signal is inputted, and reducing an inertial travel quantity. CONSTITUTION:The input of a sensor signal is discriminated in automatic mea surement and when the sensor signal is turned on, a specified speed is cleared forcibly to zero, but when the sensor signal is turned off, end processing is performed. Then the rising of the sensor signal is discriminated and only when the sensor signal changes from turn-off to turn-on, the position deviation quan tity is reduced, so that the inertial travel quantity is also reduced. Thus, the inertial travel quantity at the time of the sensor signal input in the automatic measurement is reduced to reduce an influence exerted upon the sensor because the displacement quantity of the sensor is small even if the automatic measure ment is speeded up. The initial state of the sensor is stable and the fast, high- accuracy automatic measurement is possible.
