Title: Dewing water discharge device for heat fixing device in electrophotographic device
Inventor: AKIYAMA KEIICHI
IPC: G03G15/20
Filed: 1986-12-22
Abstract: PURPOSE:To prevent a image from becoming dirty and also, bringing the inside of a casing the high humidity, and to effectively utilize the titled device so that electric discharge is generated at a low voltage, by leading dewing water which has been dewed on the lower face of a top board of a heat fixing device into a casing of at least one of an electrostatic charger a and a transfer device through a communicating path from a gutter. CONSTITUTION:In a heat fixing device 17A, when fixation of a toner image to a form 7 is repeated, moisture in the form 7 evaporates and dewing is generated on the inside surface of a top board 18A. This dewing water D is led into a gutter 23 from a side wall 22, and thereafter, led into a casing of a transfer device through a communicating pipe. Accordingly, such a state that waterdrops D drop down onto the form 7 and an image is contaminated, or wrinkles generated on the form 7 are avoided. On the other hand, the inside of the casing of the transfer device becomes high humidity atmosphere due to the waterdrop which has been led in, therefore, a corona discharge is generated. Accordingly, a working current for the corona discharge can be reduced.

Title: Unidirectional water-permeable sheet
Inventor: YAMAMOTO YASUMASA
IPC: B32B5/16
Filed: 1993-12-06
Abstract: PURPOSE:To provide a unidirectional water-permeable sheet with the property of passing water only in one direction by a method wherein the diameter of a particle of a fine particle layer is made larger than the maximum diameter of a pore of a porous sheet and a hydrogel layer is made so dense that no particle is passed therethrough. CONSTITUTION:A hydrogel layer 1, a fine particle layer 2 and a porous the sheet layer 3 are laminated successively and the diameter of a particle 5 of the fine particle layer 2 is made larger than that of a pore 6 of the porous sheet layer 3. The hydrogel layer 1 is made so dense that no particle 5 is passed to outside. In the case of a high water pressure on the side of the hydrogel layer 1, the hydrogel 4 holds the particles 5 against the pores 6 due to its flexibility to block up the pores 6. In addition to this effect, the water flowing from the initial hydrogel layer 1 to the porous sheet 3 causes the particles 5 to block up the pores 6 so as to prevent the water passage. Conversely, in the case of a high water pressure outside the porous sheet layer 3, no blocking action of the particles 5 is exerted on the pores 6 due to the flexibility of the hydrogel layer 1 and owing to the water stream in the pores 6 so as to permit the water passage.
