Title: Preventing plate for intertexture of tip of weft yarn
Inventor: HARADA HIROSHI
IPC: D03J1/04
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To provide a preventing plate, capable of surely restraining the tip of a weft yarn and preventing the generation of a weaving defect caused by an intertexture thereof in a loom equipped with a stretch nozzle for capturing the tip of the weft yarn, while avoiding an increase in operational cost. SOLUTION: This preventing plate for an intertexture of a tip of a weft yarn, is obtained by fixing the preventing plate 1 for the intertexture, extended toward the warp yarn direction at the reverse side of a main nozzle and the outside of ear of a cloth part or a catch cord, forming a slit 11 in the warp yarn direction on the plate 1 at a frame of a loom, providing a rear end opening part 15 sending forth toward the rear direction on the slit 11 and also a yarn hooking part 13 crossing to the extended direction in the front direction thereof, giving a shape of vertically crossing a virtual plane P containing an advancing locus of the weft yarn during a reed striking process to the yarn hooking part 13. Thereby, on retreating the stretch nozzle together with a reed, the yarn hooking part restrains the tip of the weft yarn becoming free for suppressing the folding back thereof.

IPC: B41J29/46
Filed: 1985-03-01
Abstract: PURPOSE:To permit the actual feeding condition of an object to be transfer- printed to be detected by a method in which when a given value is obtained before an object to be transfer-printed is detected by the second sensor following the detection of the object by the first sensor, it is judged as anomalous feeding. CONSTITUTION:When the tip of a cut paper is detected by a paper sensor 40, the counting action of pulse number by the counter 191a of the main controller 191 is started. Under such a condition, whether the tip of a cut paper is detected by a paper tip sensor 41 is detected or not is judged. When the tip of the paper is not detected, the feeding of the paper is continued. In this case, before the tip of the paper is detected by the sensor 41, anomalous feeding of the cut paper, e.g., blocking of the paper, etc., is judged by the main controller 191 when the count value of the counter 191a reaches a given value.

Abstract: PURPOSE:To increase a draft and to reduce the size of equipment by controlling the width of coating a lubricating agent to small-diameter work rolls according to a sheet width and adjusting the coating amt. of the lubricating agent in correspondence to the draft, sheet thickness and the circumferential speed of the rolls. CONSTITUTION:Lubricating agent coaters 21a, 21b are respectively disposed to the small diameter work rolls 8a, 8b on the inlet side of a four high mill 7 driven by back up rolls 9a, 9b. A lubricating agent supplying device is constituted of a coating width controller 23, a coating amt. controller 24, a pump 25, and a tank 26.

The coating amt. of the controller 24 is further adjusted according to the rolling conditions such as draft and inlet side sheet thickness. Since the generation of slips is prevented, the draft per pass is increased and the rolling torque and load are greatly reduced and, therefore, the size of the equipment is reduced.

More specifically, it is further divided into up to 1/15 discrete electrodes 31a. This construction makes it possible to cover the variability of dielectric constant of a board to be used for the manufacture of a capacitor net work with a small number of electrode patterns. It is, therefore, possible to minimize the number of screens to be prepared compared with the prior art construction and simplify its management.

Abstract: PURPOSE:To automatically feed a sheet member reliably in a simple mechanism by providing driving rollers of paper feed and discharge means, one of which is formed by high friction material and driven rollers pressed to the driving roller, and setting a coefficient of friction of the paper feed roller higher than that of the discharge roller. CONSTITUTION:In case of setting a lot of sheets, at a point of time the leading end of a document does not gets to a paper discharge roller 32, pressing force W to the rollers 31, 32 is applied to driven rollers 33, 34 by a pressing plate spring 37. Therefore, forces F, F1, F2 are applied to the lower most document of transported documents 72 in the transport direction, wherein F1 is the force for gripping the document by the first separation piece at the first separating station, and F2 is the frictional force given by the second separation piece at the second separating station, both forces being directed to the right. The force F is the force applied to the lower surface of a document through the roller 31 by W, and directed to the left. That is, the transport force is F-(F1+F2). In this arrangement, material of the paper feed roller has a high coefficient of friction than that of the paper discharge roller to enlarge the value of F, so that paper can be fed stably.

Title: Synchronizing circuit
Inventor: YAMADA YASUAKI
IPC: G11B20/10
Filed: 1995-02-06
Abstract: PURPOSE: To perform pulling into synchronization qcuickly even if the amount of bit slip is large. CONSTITUTION: At first, it is assumed that synchronization detection is performed on the side of a detection protecting part 22. When a bit slip occurs, the synchronization pattern is not detected within an estimating range. The synchronization pattern is interpolated by a judging circuit 14, and the detecting state becomes 'L'. On the other hand, the synchronization pattern is inputted to the side of a detection protecting part 32 from an AND gate 12, and the pulling into synchronization in performed. When the synchronization pattern enters the estimating range, the entrance is detected with the judging circuit 24, and the synchronization signal output is obtained. The detecting state becomes 'H', and a conciliating circuit 34 is switched to the side of the detection protecting part 32. Therefore, the output synchronization signal of the detection protecting part 32 is outputted from an output terminal TC in place of the detection protecting part 22 hereinafter.
