The driving power transmitting apparatus for use in twin shaft type extruder is constituted by a first screw driven by a power transmission shaft through a coupling member, and a second screw is driven by two parallel sets of idle plane gear, an idle shaft and an idle helical gear and a helical gear secured to the drive end. The two sets of idle plane gear are driven by a plane gear which is mounted on the power transmission shaft to be rotatable. The plane gear is driven by a prime mover through a coupling.

When a signal level of a motor brush switching signal is low and thus dropouts or omission of the pulse signals converted by a waveform shaping part take place, so that an interval between a pulse signal to be currently counted and an immediately preceding pulse signal thereof becomes longer than a predetermined average interval, a pulse signal counter makes a correction of the number of counts by adding one pulse to the pulse to be counted. Therefore, even if the signal level of the motor brush switching signals generated from a vertical motion motor M2 is low for some reasons, accurate control can be exercised over the number of rotations of the vertical motion motor M2.

Disclosed is a numerically controlled grinding machine for grinding a tapered surface of a workpiece. In the grinding machine, a workpiece having a tapered portion and a reference end surface is supported on a traverse table in such a way that the workpiece is rotatable about an axis intersecting the Z-axis at a predetermined angle, which is equal to an angle formed between the tapered surface and the rotational axis of the workpiece. In addition, a measuring device for measuring the position of the reference surface is mounted on the wheel head.

Provided is a rear wheel toe angle control system that can prevent the impairment of the tracking performance of the electric actuator and enable the rear wheel toe angle control system to ensure the stability of the vehicle even when the electric actuator for steering the rear wheel according to the operating condition of the vehicle is subjected to an axial force. An ECU (12) serving as a rear wheel toe angle control unit for variably controlling the rear wheel toe angle (δr) of the motor vehicle (V) by using an electric actuator (11) is provided with a duty ratio correcting unit (25) that corrects the target duty ratio (Dtgt) for achieving the target rear wheel toe angle (δrtgt) according to the load condition of the electric actuator (11) that depends on the lateral acceleration (Gy) of the motor vehicle (V).

In a device for diving an EC dimming mirror, an oscillation circuit generates pulse signals which change in the duty factor in accordance with quantity of surrounding light and quantity of rear light. An integration circuit integrates these pulse signals and outputs DC voltage corresponding to the duty factor. The DC voltage produced by the integration circuit is subjected to a processing for shifting a sensitivity curve in parallel by a voltage operation circuit, is limited in upper and lower limit values by a voltage limiting circuit and then is applied to an EC element through a drive circuit (28) to control the amount of coloration of the EC element.

Each of two screw bodies includes a feed screw and a kneading screw. The feed screw is formed of a wide-flight 1-lobe intermeshing screw designed so that the ratio W.sub.0 /D of the flight width W.sub.0 thereof to the screw diameter D ranges from 0.2 to 0.4. The kneading screw includes a plurality of double tipped kneading discs designed so that the ratio W/D of the width W thereof in the axial direction of the screw bodies to the screw diameter D ranges from 0.3 to 1.0, and displaced from one another in the circumferential direction of the kneading screw, the angle by which any two adjacent kneading discs being displaced range such that at least a backflow of an extrusion material can be prevented.

To provide a toe angle changing control ECU for controlling a toe angle of wheels of a vehicle. The toe angle changing control ECU includes: a straight traveling state judging section (41) for judging whether or not the vehicle is in a straight traveling state within a predetermined time period based on detection results (a vehicle speed, a steering torque, a yaw rate, and a lateral acceleration) of the traveling condition of the vehicle; a memory (44) for storing the toe angle of the wheels while the vehicle is in the straight traveling state; and a toe angle setting section (43) for setting the wheels to the toe angle stored in the memory (44) when the straight traveling state judging section (41) judges that the vehicle is in the straight traveling state. While the vehicle is in the straight traveling state, the wheels are set to a toe angle at which the wheels are substantially parallel to the longitudinal direction of the vehicle, and the rolling resistance of the wheels becomes minimum theoretically. Thus, the fuel consumption can be improved.

In the vicinity of the (100) plane, planar channeling by (100) type crystal planes, which are (011) plane and (011) plane according to the (100) surface plane, degrades uniformity of ion implantation. Therefore, a major surface of the substrate is established at a plane perpendicular to a crystal orientation forming an angle greater than or equal to 3.5.degree. with two planes perpendicularly intersecting the (100) plane. Namely, in consideration of fluctuation in setting to an ion implantation device and ion implantation angle, the substrate having surface orientation within a range 104 is employed. Also, by limiting the orientation to be less than or equal to 10.degree. from the (100) plane, ion implantation can be performed perpendicularly to the substrate without modifying the process condition. The result of the foregoing is a semiconductor substrate which will never cause planar channeling even when ion implantation is performed in a perpendicular direction to the surface of a semiconductor substrate of silicon.

A feed mechanism for a machine tool having an improved stop mechanism which includes a movable stop, a stationary stop, and a rotatable control member. The stationary stop is located on a rotational path of the movable stop which is freely rotatable about a handle shaft. The control member, which can be rotated together with the handle shaft, is adapted to rotate the movable stop together therewith except through a predetermined angular extent, such that the handle shaft for feeding a movable unit of the machine tool may be rotatable more than the movable stop by the predetermined rotational extent.
