Title: Measuring device for characteristics of fluid
Inventor: MATSUSHIRO RIYUUICHI
IPC: G01N11/16
Filed: 1983-04-16
Abstract: PURPOSE:To obtain a compact, long-life measuring device for fluid characteristics by forcing a piezoelectric oscillator provided in oil to oscillate, measuring the amplitude of the output signal of the piezoelectric oscillator and calculating the viscosity of the oil, and detecting the deterioration of the oil. CONSTITUTION:The piezoelectric oscillator 1 is inserted into the bottom part of the oil pan of an engine and put in the oil. A pulse generator 30C generates a pulse signal of frequency equal to the characteristic frequency of the oscillator 1, and its oscillation output is supplied to an electromagnetic coil 6 from a constant current circuit 30-D as an exciting signal through lead wires 6a and 6b to allow the oscillator 1 to oscillate according to the output. The output signal of the oscillator 1 is passed through lead wires 5a and 5b and converted by a differential amplifier 30E, rectifying circuit 30F, and smoothing circuit 30G into a DC signal proportional to the amplitude, and amplitude data A is obtained by an A/D converter 30H. The output signal of a temperature sensor 31 in the oil is converted by an A/D converter 30B into temperature data T, which is outputted. A main arithmetic circuit 30J reads the data T and A and the deterioration of the oil is detected on the basis of those data.

Abstract: PURPOSE:To shorten a span of machining time as well as to improve the accuracy of finishing by preventing an undue torque from being imposed on a tool, and prolonging the extent of tool life. CONSTITUTION:A spindle rotating mechanismic part 4 rotating a drill 10 attached to a tip free of detachment shifts forward and backward to and from a work 11 by means of feed machanismic part 3. Machining torque added to the drill at the time of machining is detected by a magnetostrictive torque sensor 16, transmitting it to a torque controller 15 in which the given torque desired value is compared with the machining torque, and when three is a difference between them, a feed rate for according them with each other is found out, thereby outputting a speed command signal to a feed motor driver 12. In this way, the machining torque is accorded with the torque desired value. Therefore, no excessive torque is added to the drill and thereby the progress of deterioration becomes retarded. In addition, the drill is fed at a high speed under the condition that suchlike excessive torque is not added at all.
