Title: Winding tension control device for winder
Inventor: YARII SEIJI
IPC: B65H23/198
Filed: 1986-05-07
Abstract: PURPOSE:To control the winding tension of a web material by applying the constitution wherein the torque control mechanism of a drive motor is given mechanical loss correction values for the number of revolutions and for weight, corresponding to the number of drive motor revolutions and the weight of a take-up roll. CONSTITUTION:When the number 'N' of the revolutions of a drive motor 6 has risen or dropped, a mechanical loss compensation device 13 gives a mechanical loss correction value (I') for the number of revolutions to the torque control mechanism 9 of the drive motor 6, corresponding to said rise or drop of the number of revolutions. Furthermore, when the weight 'W' of a take-up roll 1 has increased, said device 13 gives a weight mechanical loss correction value (I'') to the torque control mechanism 9 of the drive motor 6, corresponding to the increase of the weight 'W'. As a result, an effect due to a mechanical loss is corrected. Therefore, the torque of the take-up roll 1 does not fluctuate and the winding tension of a web material 2 gives no change. The winding tension of the web material 2 is controlled to high precision and the web material 2 can be taken in properly.

Title: Recovery/granulation of waste agricultural plastic film and system therefor
Inventor: NISHIBORI SADAO
IPC: B29B17/00
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To provide the subject system designed to separate and remove stuck impurities on waste agricultural films and recover the films as a resin material so as to be recycled. SOLUTION: This system works as follows: waste agricultural films are crushed into plural chips, which are then subjected to impact grinding force as well as centrifugal force; thereby, for stuck oil impurities, the chips are beaten by impact grinding force, mainly by impact force, to effect separation of oil from the chips, and on applying centrifugal action onto the chips and oils thereon, the centrifugal force on the chips is suppressed due to the impact grinding force, but the centrifugal force on the oils cannot be suppressed, therefore, the oils can be separated easily from the chips owing to the centrifugal force difference, thus washing the chips; during the above process, the chips are granulated by the aid of the impact force, grading a resin material resulted from the waste agricultural films to afford a recovered resin material to be used as a feedstock.  The other stuck impurities can be separated and removed more easily than the oils.

IPC: F02D41/14
Filed: 1991-05-10
Abstract: PURPOSE:To compensate an air-fuel ratio sensor for deterioration by correcting a fuel feed amount through comparison of a target limit current, decided according to especially an operation state, with the actual limit current of the air-fuel ratio sensor, in a limit current control system air-fuel ratio control. CONSTITUTION:A target limit current optimum to an operation state is stored and a first correction amount of a fuel feed amount is decided according to a deviation between the target limit current and a limit current detected by an air-fuel ratio sensor. Further, a correction amount of a second fuel feed amount to compensate for a deviation between the stored limit current and an actual air-fuel ratio sensor output is decided.

Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To improve the biting into pinching rolls, and effectively perform an air removing by specifying the width of a conveyor belt to the width of a folding body. SOLUTION: A wide film being released from the stock roll, is folded on a primary conveyor belt 10 which protrudes from a floor surface and is stopped in such a manner that the center of a folded body 1 may become the center of the primary conveyor belt 10. In addition, when being released from the stock roll, the film folding width (d) is larger than the width W1 of the primary conveyor belt, and when the relationship of the following equation; W1/d=0.1-0.5, is satisfied, the folded body 1 being formed, can keep a stable shape. Then, by driving the conveyor, the folded body 1 is transferred onto a secondary conveyor belt 20 by a transfer guide plate 12. The transferred folded body 1 is pinched between pinching rolls 21, 21' on the secondary conveyor belt 20 with a larger width, and an air removing is performed.  In this case, when the width W2 of the secondary conveyor belt is made larger than the folded width (d) of the film, the biting into the pinching rolls is improved, and the air removing becomes more effective.
