Title: Rolling differential screw feed mechanism
Inventor: SAWADA KATSUHIDE
IPC: F16H25/20
Filed: 1988-12-27
Abstract: PURPOSE:To improve efficiency and durability further simplifying and miniaturizing a structure contriving the setting of a lead within a wide range by meshing a drive screw shaft with an external thread of a roller screw of the same pitch, rolling rotatably providing the roller screw following the rotating of the drive screw shaft and forming the roller screw and the screw shaft in a different effective size. CONSTITUTION:A drive screw shaft 13 and a roller screw 28 are pressed to each other by magnetic force of a magnetic circuit, formed between the drive screw shaft 13 and side plates 25A, 25B, by a permanent magnet 29 giving a preload pressing the screw 28 to the screw shaft 13. Under this condition, when the screw shaft 13 is rotated by a motor 15, the screw 28, while it rolls rotating following the rotating of the screw shaft 13, is moved in the direction of its axial line, moving a table 21 because an external thread 12 of the screw shaft 13 is meshed with an external thread 27 of the screw 28. Here because the threads 12, 27 are formed in a reverse thread to each other further with the thread 27 a little larger in its effective size D than the effective size (d) of the thread 12, the table 21 is moved by a fine lead very smaller than a pitch P of the thread 12.

Title: Sliver supplying in spinning machine
Inventor: MORITA TAKAMASA
IPC: B65H54/78
Filed: 1993-12-27
Abstract: PURPOSE:To enable the supplying a sufficient packed volume of sliver to all spindles without causing any trouble by using a space required for the arrangement of only four rows of cylindrical cans, even in a spinning machine which has such a spindle pitch as to require five-rows arrangement of can in its back side when the cylindrical cans are used. CONSTITUTION:Can-transferring apparatuses 2a and 2b are placed in two rows parallel with the longitudinal direction of a flyer frame 1 in its back side. The flyer frame 1 has such values of pitch and number of the spindles la as to require five rows if the cylindrical cans would be used for supplying sliver to all spindles. On each of the can-transferring apparatuses 2a and 2b, cans 3 of a half number of the total spindles are placed in a raw in such a manner that the longitudinal direction of the cans coincides with the sending-out direction of the sliver S. The can 3 is a case with a bottom, which has a rectangular cross section having the ratio of width vs. length of about 1:4-5 and is designed to have almost the same amount of volume as that of the cylindrical can. Sliver S in each can 3 is supplied to each corresponding spindle 1a via a corresponding feed roller 14 placed above the can 3.

Abstract: PURPOSE:To improve the bit error rate by switching a time constant of each loop filter of a differential 4-phase shift keying DQPSK demodulation section and a differential exchange bit clock reproduction section from a fast time constant into a slow time constant with a frame synchronizing monitor signal. CONSTITUTION:An output of a BPF 1 is inputted to a DQPSK demodulation section 10 and a difference conversion bit clock recovery section 13. In this case, a switch 14 selects a loop filter with a fast time constant to apply bit clock recovery and differential conversion. A frame synchronization detection protection circuit 18 detects a frame synchronizing signal included in a data (f) to apply frame synchronization. In this case, a frame synchronization monitor signal C goes to an H to switch a loop filter 19 with a slow time constant of a demodulation section 10. Then the result is ANDed with the signal C at an AND gate 21 and an output of the AND gate 9 switches the switch 14 of the recovery section 13 to a loop filter 22 with a slow time constant. Thus, the accuracy of the sampling period is improved.
