Title: Contaminated matter removal from hollow fiber membrane and device therefor, and working of hollow fiber membrane
Inventor: ITO KANICHI
IPC: C02F1/44
Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To provide a contaminated matter removing method and a device therefor capable of removing the contaminated matter on a membrane surface with fine bubbles or electrical repulsion by using the whole outside surface of a hollow fiber membrane as a cathode and arranging an anode so as to be capable of uniformly impressing voltage in a hollow fiber membrane module, and a working method of the hollow fiber membrane. SOLUTION: Voltage is impressed using the membrane outside surface 2 of raw water side as the cathode and the membrane inside surface 3 of clarified water side as the anode by electroless plating a conductive metal on both surfaces of the inside and the outside of the hollow fiber membrane 1. Because the distance between both electrodes is regulated by the thickness of the hollow fiber membrane and precisely kept constant and the thickness of the membrane is remarkably thin, the electrical resistance of water between both electrodes is small and the current is stabilized. The electroless plating is an essential requirement to enable the above method and the plating is easily performed by forcibly circulating a plating solution using the machinery and material constituting the module as it is.

The wavelength range is 500-1,050Angstrom . For example, an Si wafer 109 is heated up to 700-800 deg.C to be irradiated horizontally to 109 surface with the spectral light with wavelength of 800-1,000Angstrom . The light on the Si wafer 109 surface is beams 2mm long in the vertical direction and 6mm wide in the horizontal direction to the wafer surface. Resultantly, an Si with excellent quality even at low temperature is epitaxially grown on the part irradiated with the beams better than on the part not irradiated with the beams.

Abstract: PURPOSE:To prevent occurrence of a breakage accident beforehand by grasping the occurrence of a larger voltage fall to one trolley line than that to the other trolley lines, and taking measures to boost a reduced feeder line voltage to prohibit a train from getting over an air section. CONSTITUTION:A differential potential of a trolley line air section is taken in by a data taking means 10A and taken out by an adjacent feeder line differential potential detecting means 10B. When a number of trains get into a single trolley line to let a differential potential at the air section exceed a prescribed value, charging a rectifier is immediately executed by a rectifier charging means 10D to restore a voltage. In case the voltage cannot be restored by charging the rectifier, a train operation limit processing information is sent from a train wireless alarm means 10E to a train wireless signal generating means 12, and a wireless signal is transmitted from the generating means 12 to trains 6A, 6B, so the train receiving the signal stops at the nearest station.
