Title: Membrane separation device
Inventor: SAWADA SHIGEKI
IPC: C02F1/76
Filed: 1993-12-22
Abstract: PURPOSE:To prevent the contamination of a separation membrane due to the oxidation and deposition of soluble manganese on the secondary side of a membrane module so that permeation rate can be maintained at a high level by removing manganese from water having passed through the module after adding chlorine and using the water from which maganese has been removed as cleaning water. CONSTITUTION:Water having passed through a membrane module 1 is drawn out therefrom, into which water chlorine is injected and the water is led into a particle packed tower 2. In the tower 2, maganese oxide particles having been deposited by the injection of chlorine into the water are removed and the treated water free from manganese is discharged to the outside through a treated water tank 3. At this moment, pumps P1, P2 are stopped, a pump P3 is actuated, a valve V2 is closed, and a valve V3 is opened to feed the treated water in the tank 3 to the secondary side (side of water having passed through the module) as back washing water via pipes 18, 14. By this method, the contamination of the separation membrane due to the oxidation and deposition of the soluble manganese on the secondary side of the module 1 can be prevented, so that permeation rate can be maintained at a high level.

Filed: 1988-12-26
Abstract: PURPOSE:To enable data to be identified without limitation by the color or pattern of a cloth and a dye by using irradiation light containing a large quantity of short-wavelength ultraviolet light when information is applied using a fluorescent dyestuff ink which is pumped by short-wavelength ultraviolet light. CONSTITUTION:An ink to be applied by an ink jet method is prepared as follows : for example, an oxine-zinc complex as a fluorescent dyestuff, Pluronic F108 (a dispersing agent), ethylene glycol (a dry-preventive agent), and ion exchange water are ground by a sand grinder to be dispersed, filtered, and deaired under vacuum. By using this ink, necessary data is applied to a cloth under a specific ink jet condition. In the use of a portable short-wavelength UV lamp containing short-wavelength ultraviolet light more than long-wavelength ultraviolet light, the irradiation light of the short-wavelength UV lamp makes fluorescent light from numeric data fluoresce higher than that from a fluorescent whitening agent so that the numeric data can be correctly identified with the naked eye.

Title: Retainer for roller bearing
Inventor: KATO YOSHIO
IPC: F16C33/38
Filed: 1994-12-28
Abstract: PURPOSE: To enhance fluidity of grease on a raceway by providing grooves of which width in circumferential direction is increased gradually from an end part to a pocket in the outer diameter. CONSTITUTION: Grooves 4e of which width in circumferential direction is increased gradually from an end part 4d facing a seal to a pocket 4a are provided in the outer diameter of a retainer. Also the wall thickness part of the outer diameter which constitutes the both side walls 4e1 and 4e2 of the grooves 4e forms a projected part 4f projectedly from the end part 4d. When the retainer is rotated in Y direction during the rotation of a bearing, the wall surface 4e1 in the counterclockwise direction of the grooves 4e acts as a kind of spiral vane so as to produce a force to flow grease on the end part 4d forcibly to the pocket 4a side. On the contrary, when it is rotated in the X direction, the wall surface 4e in the counterclockwise direction acts as a spiral vane.  Thus grease flows to the outer diameter side by the rotation of the bearing, and grease remained near the land of an outer ring and grease adhered to the inner wall surface of the seal flows to the pocket 4a side along the grooves 4e.
