Abstract: The present invention provides a method for hydrophilizing an external-pressure type hollow fiber membrane module, which is capable of efficiently hydrophilizing the hollow fiber membranes even in the vicinity of the bonded/fixed portion in the lower part of the casing. According to the hydrophilization method of the invention, the outer surfaces of the hollow fiber membranes in the lower part of the casing are prevented from receiving a water head pressure corresponding to the height of the membrane module and the hollow fiber membranes located in the vicinity of the lower bonded/fixed portion can be efficiently hydrophilized.

Abstract: A method and a device for coating a hollow cylindrical member. The method includes radially coating an entire inner surface of the hollow cylindrical member with a first coating material discharged by a first slit nozzle and simultaneously circularly coating an entire outer surface of the hollow cylindrical member with a second coating material discharged in an axial direction of the hollow cylindrical member by a second slit nozzle located opposite the first slit nozzle with the hollow cylindrical member therebetween. The first slit nozzle and the second slit nozzle discharge the first coating material and the second coating material, respectively, to a same height of the hollow cylindrical member relative to the inner surface and the outer surface thereof.

Abstract: A fixing apparatus including at least one transfer and fixing member which is placed in contact with an image carrier and a recording medium and configured to transfer and fix an image on the image carrier to the recording medium, at least detection mechanism configured to detect a jam generated on the recording medium, a separation mechanism configured to contact the transfer and fixing member with and separate from the transfer and fixing member from the image carrier or recording medium, the separation mechanism being configured to separate the transfer and fixing member from the image carrier or recording medium when the jam on the recording medium is detected by the detection mechanism.

Abstract: A coating film forming apparatus, which applies a paint to an outer circumferential face of an object to be coated to form a coating film, the coating film forming apparatus, includes: a retention section which retains the coated object in a state in which the outer circumferential face is exposed and in which an axial core of the coated object is in parallel with a vertical direction; an applying nozzle formed in an annular shape, arranged to oppose the outer circumferential face and to have an interval therebetween, and coaxially arranged with the coated object retained by the retention section, the applying nozzle having a first slit, which discharges the paint to an inner circumferential face formed throughout a whole circumference thereof; a movement section, which relatively moves the retention section and the applying nozzle along the axial core; a paint supply section which supplies the paint to the applying nozzle; and a gaseous body discharger which discharges a gaseous body toward the paint dischar

Abstract: The present invention is directed to a coating film forming apparatus 1. The apparatus 1 includes a coating unit 11, a coating material supply unit 10, and a control unit 12. The coating unit 11 contains a holding unit 18 for holding a substrate 4, a coating nozzle 19, and a movable unit 20. The coating nozzle 19 is provided with a slit for discharge coating material to an inner circumferential surface, formed in annular shape. The movable unit 20 moves the coating nozzle 19 along a shaft center P of the substrate 4. The control unit 12 controls to apply coating material 7 to an outer circumferential surface 4c of the substrate 4 from a lower end 4a upward in order.
