IPC: H02K7/08
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To reduce a thrust load due to the weight of a main spindle and prevent a thrust load over designed pre-load from being applied to the bearing system of the main spindle by fitting a stator to a rotor so as to be displaced in the axial direction, in a main spindle device rotating the main spindle by a motor composed of a rotor and a stator. SOLUTION: A main spindle 1 is journaled with respective bearings 2, 3, and the one end of a rotor 4 is positioned on the main spindle 1 by a collet bush 5. Hereat, a stator 8 is fitted to a sleeve 6 so as to be displaced in the axial direction by displacement A against the rotor 4. Suction force generated in the direction eliminating the displacement from each other in response to the displacement of the rotor 4 and the stator 8 is previously measured, and this displacement A is set to be displacement at balancing the thrust force applied to the bearings by the weight of the main spindle 1 with the suction force.

Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To simplify the constitution and reduce costs, by transmitting individual drive changeover signals to all drivers' seat units through the first signal line when any operation signal is not detected within a specified time and IG signals are input. SOLUTION: An input/output I/F24 detects at every specified time interval the presence of the operation signal of the driver's seat switch 11 in data lines 5 and an IG signal is transmitted to one of other seat units by an IG line 6b. When any operation signal is not detected within a specified time and an IG signal is input, the driver's seat switch is regarded as failure, and an individual drive changeover signal changing over from the common drive of the motors 23, 33, 43 of all other seats by the driver's switch 11 to individual drives of the motors of respective other seats by respective other seat switchs 21, 31, 41, is transmitted to all other seat units 2-4 through the line 5 by the CPU 22. Accordingly, since individual drive changeover signals are transmitted to all other seat units by using an existing data line, the system can be simplified and the cost can be reduced.

Abstract: PURPOSE: To reduce noise and abrasion and cut working time by supporting a roller having an eccentric outer peripheral surface and a wheel driven by the first spindle with the spindle pin of an eccentric wheel drive placed eccentrically on the second spindle driven by the first spindle. CONSTITUTION: A spindle 1 and a spindle 3 rotate in parallel to each other at the same rotational speed. A spindle pin 9, positioned so as to be eccentric relative to the spindle 3, generates reciprocating and oscillating motion of a coupling element 15 in connection with a guiding slit 13. In synchronization with it, a crank 21 generates reciprocating motion 25 of a rod 19. Therefore, a polishing tool holder 20 travels on an elliptical or a circular trajectory. In addition to this fundamental motion, an oscillating motion is generated by an eccentric roller 10. The roller 10 rotating at a high speed generates the vibrating and oscillating motion of the coupling element 15, which is superimposed on the elliptical trajectory.

Abstract: PURPOSE:To make it possible to measure the mixing amount of admixture simply and quickly by trapping the volatile component evaporated from the admixture in unhardened concrete, and measuring the concentration of the component. CONSTITUTION:A volatile component G evaporated from admixture 6 in ready-mixed concrete 2 is transmitted through a Teflon film 5 and collected in a gas trap 7 which is provided in a detecting probe 3. The component is sent with the air from a blast tube 8 and reaches the upper part of the trap 7. A gas detecting part 9 detects the concentration of the component G as a total amount or individually. A main body circuit part 13 has a voltage frequency converter and an amplifier. The concentration is converted into the signal for indicating the change in electric resistance of the sensor in the detecting part 9, and the result is outputted from the circuit part 13. In an auxiliary operating part 14, correction based on the kind of the admixture 6, control of gas-concentration detecting time and correction of humidity are performed. Whether the admixture 6 is mixed in the ready-mixed concrete or not in the specified allowance quantity is judged. The pass or fail is displayed on a display device 12a. When the component G exceeds the specified concentration, i.e. the concentration is defective, the fact is announced by a buzzer 12b.
