Title: Method for washing and regenerating separation membrane or module
Inventor: NOUZAKI KATSUYA
IPC: B01D65/06
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To provide an innovative washing method for remarkably restoring the treatment capability of separation membranes without causing an effect on the separation membranes themselves by removing a scale layer formed by adhesion of a silicon compound such as silicon dioxide (silica) mainly to the separation membrane surface by using a specified chemical agent during a membrane separation process for treating wastewater and reusing treated water. SOLUTION: In the case of purifying wastewater by a separation membrane and reusing the resultant water, a silicon compound adhering to the surface of the separation membrane is dissolved or removed by using a washing liquid whose pH is adjusted to be alkaline by adding tetrasodium ethylenediamine tetraacetate tetrahydrate. The concentration of the tetrasodium ethylenediaminetetraacetate in the whole solution of the washing liquid is preferably not lower than 0.1 to lower than 10 wt.% and the pH of the washing liquid is preferably within the range from 9 to 12 and further, 50-1, 000 ppm of an anionic surfactant or a nonionic surfactant is preferably added to the whole solution.

Title: Ink ribbon cartridge
Inventor: MURATA HIROICHI
IPC: B41J33/52
Filed: 1985-06-18
Abstract: PURPOSE:To uniformize a tention on an ink ribbon and prevent defective printing from being caused by sagging of the ink ribbon at a printing part, by setting a rotation resistance to be larger when the roll diameter on a payout core is large and to be smaller as the roll diameter becomes smaller. CONSTITUTION:In the beginning stage after the start of use of the ink ribbon A, only a small portion of the ink ribbon A is taken up around a take-up core 12, so that the roll diameter on the take-up core 12 is a small, and the position of the core 12 is deviated to the right side. Therefore, the payout core 7 is pushed by a tip part of a tension spring 10, and a strong rotation resistance is exerted thereon. On the other hand, in the final stage of the use of the ink ribbon A, a major portion of the ribbon A is wound around the take-up core 12, so that the roll diameter on the core 12 is large, and the distance between the core 12 and a driving rotating body 18 is enlarged, resulting in that the core 12 is gradually moved leftward. As a result, the core 17 is pushed by a part near a fulcrum part 17 of the tension spring 10, so that a small rotation resistance is exerted thereon.

IPC: D03D49/20
Filed: 1989-05-27
Abstract: PURPOSE:To prevent mutual collision of cloth rolls by prohibiting a loom from stopping operation thereof and a temporary shed cart from backing to a loom calling for a cart until a signal for completed transfer of the full cloth roll to a temporary shed position is transmitted. CONSTITUTION:When transfer of a cloth roll in a full package state from a cloth roll mounting position of a loom to a temporary shed position is completed, data on the completed transfer are transmitted from a cart control computer to a control computer on the side of a calling computer. Before receiving the aforementioned data, if the cloth roll diameter on the cloth roll mounting position attains a prescribed diameter, operation of the loom is stopped by the control computer on the side of the loop to avoid an increase in the cloth roll diameter and interference with the cloth roll on the temporary shed position. Furthermore, the temporary shed cart is prohibited from backing to the calling loom until the data on the completed transfer are transmitted to avoid mutual interference of cloth rolls.

IPC: F02P17/12
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a misfire detection device of an internal combustion engine capable of certainly detecting misfire even at the time when an ignition plug smokes. SOLUTION: A degree of lowering of insulation resistance due to smoking of an ignition plug 12 is measured by taking up voltage to a microcomputer 18 at both ends of a detection resistance 16 during a period except a period when ion is generated at the time of normal combustion of mixed gas in a cylinder by discharge of the ignition plug 12. Though it is judged as normal firing when voltage generated on the both ends of the detection resistance 16 taken up to the microcomputer 18 during the period when ion is generated is higher than a threshold and as misfire at the time when it is lower than the threshold, this threshold is corrected in accordance with the degree of lowering of the insulation resistance. Consequently, it is also possible to certainly detect misfire even at the time when the ignition plug 12 smokes.
