Title: Signal reader
Inventor: HAYASHI HIDEKI
IPC: G11B20/10
Filed: 1984-10-16
Abstract: PURPOSE:To restore unlocking, to suppress damage and to improve the possibility of reading properly data by making the time constant of a loop filter small when a field sink and the unlocking of a PLL circuit are detected. CONSTITUTION:When a field sink followed by a vertical sink where the input of a terminal 1 is in a data field is detected, an FS detection circuit 3 issues a signal to a time constant switching circuit 11 to switch the time constant of the loop filter 8 to a small value. As a result, the PLL circuit responds more quickly and is locked with a bit synchronizing signal at a high speed. When a drop-out occurs for a long time, the PLL circuit in a data section is unlocked due to some reasons, or locking of the PLL circuit during the field sink period is impossible, a synchronization monitor circuit 10 detects such cases. Then a signal is outputted to the time constant switching circuit 11, and the PLL circuit is quickly locked by switching the time constant of the filter 8 to a small value.

Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To provide a low cost ink jet head in which high conversion efficiency can be sustained even when the thickness of a piezoelectric layer is increased by increasing the overall deformation of a piezoelectric element based on the cooperation of the share mode deformation of a piezoelectric layer and the expansion/contraction mode deformation of an outer piezoelectric layer and loss of generated pressure can be reduced by enhancing the rigidity of an ink pressure chamber. SOLUTION: Based on a tact that a driving voltage is applied to each first electrode 26 from a drive power supply V upon turning a switch S on, a field orthogonal to the direction of polarization is generated on the opposite sides of a piezoelectric ceramic layer 23 in order to cause deformation in share mode. At the same time, a field is generated in parallel with the direction of polarization of an outer piezoelectric ceramic layer 24 in order to deform the outer piezoelectric layer uniformly in expansion/contraction mode. According to the arrangement, volume in an ink pressure chamber 21 is reduced and the ink in the ink pressure chamber 21 is jetted through an ink jet port (not shown) toward a print paper in order to print a character or the like.

Abstract: PURPOSE:To extend life of a tube for a peristaltic pump as well as improving pump performance by detecting the operation time of a mechanism of the peristaltic pump and supplying lubricant fluid of amounts commensurate with the operation time to contact-rotating parts of the pump mechanism. CONSTITUTION:Revolution of a drive motor 2 of a peristaltic pump 1 is added up with an integrating meter 6 and inputted into a fluid supply amount control circuit 7.

IPC: D02H5/02
Filed: 1992-07-24
Abstract: PURPOSE:To improve a quality of a yarn by controlling a water content of the yarn by altering heat quantities of a preliminary drying unit and a finish drying unit without altering the heat quantity of preliminary drying. CONSTITUTION:When a water content of a yarn becomes lower than a target water content Ao as a feeding speed reaches an upper limit of the speed, an output unit 30 alters only a heat quantity command to a finish drying unit based on a deviation of the water content, drives a heat quantity regulator 35 and controls a regulator 22 in a throttling direction. When the deviation of the content is not yet eliminated even when the heat quantity of the finish drying unit reaches a predetermined range, the unit 30 starts to control a preliminary drying unit based on the deviation at that time. If it judges that the heat quantity of the finish drying unit reaches a lower limit of a temperature T2, the unit 30 operates a heat quantity regulator 36 according to a heat quantity command to preliminary drying to throttle a regulator 22a. Thus, a quality of the yarn can be improved.
