Abstract:
Provided is a paper machine contamination preventive agent that has high fixability to rolls and the like of a paper machine, that positively finds a silicone oil capable of imparting releaseability and water-repellent properties to the rolls or the like immediately upon being supplied to the rolls or the like, and that uses the silicone oil as a main component. Further provided is a paper machine contamination preventive agent using a silicone oil that permits transfer of less foreign matters from a wet paper web than that in a case where a contamination preventive agent containing a dimethylpolysiloxane base oil is a main component. The paper machine contamination preventive agent is fed to a paper machine and has a sidechain-type modified silicone oil or a sidechain both-termini modification silicone oil as a main component.
Abstract:
A lock-up clutch control device which controls a lock-up clutch provided in a torque converter installed between an engine and a transmission, is disclosed. The lock-up clutch control device changes over between a converter state and a lock-up state of the torque converter according to a differential pressure command value (LUprs) relating to a differential pressure supplied to the lock-up clutch. The lock-up clutch control device includes a differential pressure generating device (7, 8) which generates the differential pressure supplied to the lock-up clutch; input torque detection means (2, 14, 15) which detects an input torque (Te) to the torque converter; and a controller (1). The controller (1) is programmed to compute a real differential pressure (P_lu) based on the detected input torque (Te) upon completion of the engagement of the lock-up clutch; compute a learning value (P_learn(Tai)) relating to a differential pressure deviation, based on the difference between the computed real differential pressure (P_lu) and differential pressure command value (P_ref) upon completion of the engagement of the lock-up clutch, and store the learning value (P_learn(Tai)); correct a present differential pressure command value (LUprs_slp) based on the learning value (P_learn(Tai)); and send the corrected differential pressure command value (LUprs) to the differential pressure generating device (7, 8).
Abstract:
A controller (5) performs open loop control of the engaging state of a lockup clutch (2) through a switching mechanism (3, 4) when a torque converter (1) transitions from a first state in which the lockup clutch (2) is disengaged to a second state in which the lockup clutch (2) is at least partially engaged. At this time, the controller (5) estimates the engine torque at the time when open loop control ends, estimates a necessary lockup capacity required for the converter (1) at the time when open loop control ends, based on the estimated engine torque, and controls the engaging state of the lockup clutch (2) through the switching mechanism (3, 4) to make the lockup capacity at the time when open loop control ends become the necessary lockup capacity.
Abstract:
A simple method capable of effectively preventing dry part areas, at least the surfaces of cylindrical dryers, from being stained even if a spray space is absent in a paper machine. The method can prevent the contact part of the dry part (D) of the paper machine with a paper body from being stained. The dry part staining prevention method can continuously feed/apply a staining inhibitor (T) to the paper body (W) at a position just before the dry parts.
Abstract:
The present invention provides a method of spraying antipollution agent which can securely apply a proper amount of antipollution agent to a canvas of a paper machine, a spray nozzle and a slidable spray apparatus used in the spraying method, and antipollution agent. In antipollution agent spraying method of applying antipollution agent (T) to a canvas (A) used for drying paper in a paper machine, the method applies the antipollution agent (T) from a spray nozzle (S) toward a contact start position (C) between an outer surface of the canvas (A) and an out roll (B), applies the antipollution agent (T) to said out roll (B), and transfers and applies the antipollution agent (T) to the canvas (A) via said out roll (B).
Abstract:
In lock-up capacity control apparatus and method for a torque converter, the torque converter is caused to have a converter state in which a relative revolution between input and output elements of the torque converter is free of limitation in a case where a lock-up capacity (L/Uprso) during a no-load state is equal to or larger than a shock determining lock-up capacity (α), during an acceleration slip lock up in which the lock-up capacity of the torque converter is augmented by means of a time series control which accords with a load state of an engine, and the torque converter is caused to be oriented toward a lock-up state in which the relative revolution is zeroed by continuing an augmentation of the lock-up capacity by means of the time series control in a case where the lock-up capacity during the no-load state is smaller than the shock determining lock-up capacity.
Abstract:
A conductor layer is formed on an insulating film which is formed on a semiconductor substrate and which consists of a thick portion and a thin portion with a step therebetween. A film made of material having an etch rate substantially equal to that of the material of the conductor layer is formed on the layer. The film, which has a substantially flat upper surface, and the conductor layer form a laminated structure. Those portions of the laminated structure which are on the thin portion of the insulating film and said step have substantially the same thickness. A mask layer of a predetermined pattern is formed on the laminated structure. Using the mask layer, the laminated structure is selectively etched, the selected portions of the conductor layer and film being etched at the same etching rate. Thereafter, the mask layer and the remaining film are removed.

[Problems] To provide a functional composition enable a stale paper production by being applied onto a press roll, and a method for improvement of detachability using the same. [Solutions] The present invention relates to a functional composition used by being applied onto a press roll for dehydration of a wet paper, comprising a compound expressed by the following general formula (1): STR wherein R represents an organic group which may have a substituent or a hydrogen atom, p and r each independently represent an integer of 0 to 228, and q represents an integer of 0 to 69, provided that p, q and r do not represent 0 simultaneously.
Abstract:
A lock-up clutch control device controls a lock-up clutch provided in a torque converter in a vehicle. The lock-up clutch control device includes a sensor for detecting a rise of a vehicle speed; a differential pressure generator which generates a differential pressure to lock the lock-up clutch; and a controller. The controller is programmed to command the differential pressure generator to lock the lock-up clutch when the vehicle speed exceeds a predetermined low vehicle speed, after the vehicle is started; subsequently monitor the rise of the vehicle speed; and command the differential pressure generator to unlock the lock-up clutch when the monitored rise of the vehicle speed is lower than a preset value.
