Filed: 1987-05-22
Abstract: PURPOSE:To make it possible to smoothly perform intermittent drive by reciprocating a shaft with the use of a linear actuator so that the shaft is engaged with a locking part of an cuter ring having its inner periphery with which epicyclic elements are inscribed. CONSTITUTION:When a motor 1 rotates a rotary shaft 2, epicyclic rollers 3 autorotate but does not revolves since it is held by a retainer 4 secured to a bed 8, while an outer ring 5 self-travels. Meanwhile a shaft 6 is reciprocated by a linear actuator 7 and is locked with one of looking parts 5a formed on the outer periphery of the outer ring 5 within a predetermined time. At this time the self-travel of the outer ring 5 is stopped while a slip occurs on the inner peripheral surface on which the autorotating epicyclic rollers 3 roll. With this arrangement, the outer ring 6 may perform intermittent drive while the rotation of the motor 1 does not vary. Thus, it is possible to perform smooth intermittent drive with low noise and vibration while the structure of the intermittent drive device is simple.

Abstract: PURPOSE:To smoothly perform the idling, acceleration and high speed running of an engine as well as to make the promotion of an energy-saving bid attainable, by detecting a control signal from a fuel injection controller and, on the basis of this detection, controlling a compressor or an engine speed control mechanism. CONSTITUTION:A control signal Sa of an injection device 3 turns to voltage V1 in proportion to engine speed via a waveform shaping circuit 11, a monostable multiplier 19 and an integrating circuit 25 as well as to voltage V2 in proportion to fuel injection time via a turnover circuit 29 and an integrating circuit 34. And, in time of idling, it comes to voltage E1 commensurate to V1>V2, V1<6,000rpm and, with the H output of comparators 39 and 45, operates an engine speed control mechanism 51 by motion of a compressor control circuit 44, then raises up the number of revolution. In addition, in time of accelerating running, with V2>V1, the compressor is in no case rotated and therefore the number of revolution is no longer increased. In time of deceleration, with voltage E2 commensurate to V1>V2, V1>2,000rpm, the singal Sa drives the compressor but in time of more than 6,000 in revolution, the compressor and the mechanism 51 are stopped. Doing like this, each operation is smoothly performed and a bid for energy- saving is thus promoted.

Abstract: PURPOSE:To perform accurate and quick measurement, by providing a function, by which speed can be changed based on the slant angle of an operating rod, in a joy stick. CONSTITUTION:When the operating rod of a joy stick 21 is slanted in the desired direction; to which mode of modes M1-M4 the output signal Vtheta from an X direction potentiometer 28 belongs is identified in window comparator 521- 524. Namely, when the slant angle theta of the operating rod is within the angle range of the mode M1, a mode signal MS1 is outputted from the window comparator 521. In this way, the slant angle of the operating rod is divided into the four stages of the modes M1-M4 for every specified angle range. Sliding plates 8 and 10 of a work mounting table 2 are moved at a different speed for every mode of M1-M4 by pulse motors 7 and 9. Since the feeding speed can be changed by the four stages by the slant angles of the operating rod, the accurate and quick measurement can be performed.
