Title: Thread detecting sensor
Inventor: INOUE JIRO
IPC: D05B51/00
Filed: 1988-03-31
Abstract: PURPOSE:To surely detect a needle thread existence without misoperation by a sensor wherein it consists of a bending plate with a tongue, piezoelectric ceramic plates and their holder. CONSTITUTION:When a needle thread 26 is fitted with a place where it is not fitted, it is shifted from A position to B through a slit 5. According to this movement, since a tongue 13 on a bending plate 10 is depressed by the needle thread 26 on the side opposite to the slit 5 and the bending plate 10 is bent, the needle thread 26 is detached from the tongue 13, when shifted at the B position. The bending plate 10 is then vibrated. Piezoelectric ceramic plates 11 and 12 are also vibrated with the bending plate, and an electric potential difference is generated. When this electric potential difference is detected, it is detected that the needle thread 26 has been fitted. After it is detected, sewing operation is started by a sewing machine 20.

Abstract: PURPOSE:To decrease unbalanced external force as far as possible and make stable operation with a small balancing device by balancing the inertial force of a rolling mill which converts rotating motion to reciprocating motion by springs and controlling spring force by the change of the spring mounting position corresponding to a rotating speed. CONSTITUTION:The rotation of a crank arm 3 by a motor 1 is transmitted by a connecting rod 5 to a stand 8 of a Pilger mill 7 so that the stand moves back and forth. A stand 8 is connected by the springs 9 of the spring constant corresponding to the max. rotating speed in this case to balance the inertial force. Since the length ratio of the arm 3 and the rod 5 is not small, the inertial force thereof cannot be neglected. The piston A position of a hydraulic cylinder 10 is corrected by a signal J1 obtd. by calculation 13 of the detected rotating speed 12 to control the spring force. An error signal J2 by the sliding friction, etc., of the stand 8 is fed by a tension detection 15 signal to correct the piston A position of the cylinder 10. The unbalanced external force is minimized by the above-mentioned technique and the stable operation of the rolling mill is executed with the min. balancing device.

Abstract: PURPOSE:To detect the reflection signal from an object with high sensitivity by providing a counter counting a clock signal to output a count and a memory device reading memory data as a dummy random signal generator. CONSTITUTION:A counter 1 inputs a clock signal to count an input clock and performs counting from 0 to an upper limit count and, when the count reaches the upper limit value (n), the count is reset to 0 and counting is again carried out. The counter 9 repeatedly performs the counting from 0 to 127 in synchronous relation to the clock signal inputted as the upper limit value 127. A memory apparatus 2 has a memory storing data constituted by an ROM and an RAM and reads the code data of the dummy random signal stored in the memory to output the same to a signal converter 3. By this method, an unnecessary reflection signal is timewise masked and the reflected signal from an object can be detected with high sensitivity.
