摘要： A torque sensor which includes two cylinders fixed to two shafts connected with each other through a torsion bar. The magnetic coupling state of the two cylinders is made variable corresponding to relative rotations of the two shafts. The magnetic coupling state thereof is detected, which is indicative of a torque acting on the shafts. The two cylinders form at the opposite end edges thereof teeth provided with cutouts disposed circumferentially of the cylinders and are opposite to each other at portions of about half a width of each tooth. The two shafts are regulated by rotation so as to not put the teeth of the cylinders completely opposite or non-opposite to each other. This enlarges a rate of change in the magnetic coupling state, detecting the torque with high sensitivity, and reducing a lateral difference in the output.

The two cylinders form at the opposite end edges thereof teeth provided with cutouts disposed circumferentially of the cylinders and are opposite to each other at portions of about half a width of each tooth.

摘要： A steering angle middle point detecting apparatus of the invention is provided with a vehicle speed sensor for detecting vehicle speed, a torque sensor for detecting at regular intervals steering torque to be added to a steering wheel, a steering position detecting means for detecting a steering position of a steering mechanism, a means for comparing a steering torque set value previously set corresponding to the vehicle speed with the steering torque detected by the torque sensor, and a steering angle middle point calculating means for calculating a middle point of a steering angle by using the steering position of the steering mechanism detected by the steering position detecting means when the steering torque is smaller than the steering torque set value, which judges that the vehicle goes straight when the detected steering torque is smaller than the steering torque set value corresponding to the vehicle speed, and judges the steering position at that time to be the middle point of the steering angle. Further, another steering angle middle point detecting apparatus is added: a judgment of an angle velocity of the steering angle, that is, a rotational speed of the steering wheel or variation of the steering torque; determines that the vehicle goes straight when it is at the specified value or less, and judges the steering position at that time to be the middle point of the steering angle.

摘要： A pattern generating system for use in electronic sewing machines. Output-oriented data relating to the amount of bight or feed for a stitch pattern and order instruction-oriented data relating to the order in which the output-oriented data is read out are stored in a static memory (ROM) separately in such a manner as to distinguish between the data relating to bight and the data relating to feed. The data relating to the address at which the respective head data on stitch patterns is stored is stored at specified addresses in the static memory addressed by selection instructions corresponding to the stitch patterns given as by a pattern selecting button unit. The static memory is connected to a microcomputer which performs a control operation such that it indexes the static memory, analyzes order instruction-oriented data and updates addresses or gives the output-oriented data to a drive unit which controls the amount and direction of bight and feed. The connection of the static memory to the microcomputer is such that the static memory can be exchanged with another static memory having stored therein data relating to other different stitch patterns.
